Description

State of the art

The invention relates to a method of the type specified in the preamble of claim 1 and the type specified in the preamble of claim 3, as well as a method of the type specified in the preamble of claim 10 and a method of the type specified in the preamble of claim 13.

For filling liquid products, especially in the food and beverage industry, such as beverages, sauces or oils, filling devices are generally used which use a simple mass or volume-based measuring principle during filling in order to obtain a required, specified product mass and / or to fill a required predetermined product volume into a product container.

One disadvantage of known methods and devices for filling liquid products is that, under unfavorable or changing ambient conditions, too much or too little product is filled into the corresponding container, so that, for example, the container is too full and may overflow.

One of the consequences of this is that product is wasted and incorrectly filled or overfilled containers have to be sorted out. The filling device or the filling system can also be contaminated in an undesirable manner due to liquid leaking from an overfilled container.

task

It is therefore the object of the invention to provide and improve means for filling liquid or flowable products, in particular to improve, for example, the volume and / or mass accuracy with which liquid products, in particular in the food and beverage industry, can be filled into containers.

solution

This is achieved according to the invention by a method according to claim 1, a method according to claim 3, as well as by a device according to claim 10 and a device according to claim 13. Advantageous embodiments and developments are the subject of the subclaims.

  • Ein Messen der Temperatur des abzufüllenden flüssigen Produktes beim Abfüllvorgang, z.B. ein Messen der Abfülltemperatur,
  • Eine Berechnung der in das/ein Behältnis abzufüllenden Menge des abzufüllenden flüssigen Produktes auf Grundlage der gemessenen Temperatur des abzufüllenden flüssigen Produktes beim Abfüllvorgang und unter Berücksichtigung der bestimmten Beziehung zwischen der Dichte des abzufüllenden flüssigen Produktes in Abhängigkeit der Temperatur des abzufüllenden flüssigen Produktes,

An exemplary method for filling liquid products into a container, in particular liquid or flowable products in the food and beverage industry, can include one, some or all of the following steps:

• Determining a relationship between the density of a liquid product to be filled as a function of the temperature of the liquid product to be filled,
• A control of a filling system or filling device or filling machine for filling the liquid product into a / the container on the basis of the specific relationship between the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled, said controlling one, some or all of the following steps include:
  • Measuring the temperature of the liquid product to be filled during the filling process, e.g. measuring the filling temperature,
  • A calculation of the amount of the liquid product to be filled into the container on the basis of the measured temperature of the liquid product to be filled during the filling process and taking into account the specific relationship between the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled,
  • A filling of the liquid product with the calculated amount of the liquid product to be filled into the / a container.

The calculated amount to be filled of the product to be filled can be understood here in particular as a weight amount of the product that can be measured in mass units or a volume amount of the product that can be measured in volume units, which can be determined from the relationship or definition ρ = M / V, where ρ is the / is a certain density of the product, M is the product mass and V is the product volume. If, for example, a fill quantity requirement to be met is a weight quantity or a volume quantity, this relationship or definition can be used to determine if the density of the product is known / specific and if the volume is specified / to be achieved, e.g. a container volume, and / or if the density is known / specified / mass to be achieved, to calculate the corresponding weight or volume of the product to be filled.

As an alternative or in addition, said exemplary method for filling liquid products into a container can include measuring the density of the liquid product to be filled during the filling process, so that when calculating the amount of the liquid product to be filled into the container, the measured density of the liquid product to be filled is also included can be taken into account during the filling process.

It is therefore conceivable, for example, that at least two calculations of the amount of the liquid product to be filled into the container are carried out, which can be different and independent of one another. For example, a combination, e.g. a mean value, of the results for the amount to be filled of the liquid product to be filled from the said exemplary calculations for the amount of product to be filled or only one result for the amount of the liquid product to be filled from the said exemplary calculations could be used as the basis serve to fill the container with the calculated product quantity or product dosage quantity.

  • Ein Messen der Dichte des abzufüllenden flüssigen Produktes beim Abfüllvorgang,
  • Eine Berechnung der in das Behältnis abzufüllenden Menge des abzufüllenden flüssigen Produktes auf Grundlage der gemessenen Dichte des abzufüllenden flüssigen Produktes beim Abfüllvorgang,
  • Ein Abfüllen des flüssigen Produktes mit der berechneten abzufüllenden Menge des abzufüllenden flüssigen Produktes in das Behältnis.

Alternatively or additionally or optionally, an exemplary method for filling liquid or flowable products into a container, in particular liquid products in the food and beverage industry, is conceivable, which can include one, some or all of the following steps:

• Controlling a filling system for filling the liquid product into a container, comprising one, some or all of the following steps:
  • A measurement of the density of the liquid product to be filled during the filling process,
  • A calculation of the amount of the liquid product to be filled into the container on the basis of the measured density of the liquid product to be filled during the filling process,
  • A filling of the liquid product with the calculated amount of the liquid product to be filled into the container.

As already mentioned, said additional or alternative exemplary method for filling liquid products into a container can also comprise a / the determination of a / the relationship between the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled, and the calculation the in the container quantity of the liquid product to be filled can optionally, optionally or additionally take into account the / a certain relationship of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled.

The method steps and device features of a method and a device for filling liquid products into a container described here enable, in particular, an improvement in filling accuracy, since temperature-related fluctuations in the density of the products to be filled, e.g. in hot filling, and / or product-related fluctuations in the density of the products to be filled Products, e.g. from product batch to product batch, can be compensated during the filling process.

For example, compliance with the prescribed product fill quantity requirements can be made easier, as illustrated below.

For example, according to a prepackaging ordinance, an exemplary reference temperature or a reference temperature for checking the fill quantity requirement of 20 ° C. can be prescribed.

If the temperature of the product during the filling process, i.e. the filling temperature, deviates and fluctuates from said exemplary reference temperature, this has the consequence that the product density fluctuates depending on the filling temperature, especially when it is filled warm or hot and there is no product circulation for product-specific reasons can be used to keep the product in the filler hot.

Here z. B. when hot filling of sauces, temperature spreads of 70 ° C to 95 ° C occur, in which product is still filled, although, for example, the container to be filled is already overfilled.

For example, depending on the product, significant fluctuations in density, e.g. in a range of up to +/- 5%, can occur from batch to batch, in particular in the case of seasoned and ready-to-use sauces (e.g. ketchups, BBQ sauces, mayonnaise, etc.).

With both conventional mass-based and conventional volumetric filling systems, a corresponding volume deviation from the filling temperature to the reference temperature is to be expected, which, especially with product-specific density fluctuations and the filling system-related filling accuracy, drastically worsen the actual filling accuracy can and under certain circumstances reduce the saleability and increase the elimination rate in accordance with a specified prepackaging ordinance and thus lead to more product loss.

The method steps and device features of a method and device for filling liquid products into a container described here enable a significant improvement in the filling accuracy of a filling device by taking into account the temperature-related and / or product-related fluctuations in the density of the filling device, so that product losses and / or production interruptions can be minimized.

The process of measuring a density and / or a temperature of the liquid product to be filled during the filling process can be understood to mean, for example, a measurement immediately and directly during the filling process and / or a measurement in a product storage tank of the filling system and / or a measurement in the product supply to the filling system become.

For example, a corresponding measurement sensor system for measuring a density and / or a temperature of the liquid product to be filled can take place directly in an exemplary filling element / filling valve / filling valve node and / or in an exemplary product storage tank and / or an exemplary product supply line of the filling plant.

In other words, a method is conceivable, for example, which can optionally measure the density and / or the temperature of the liquid product to be filled before, during or during the filling process and, on this basis, calculate and dose the amount of the liquid product to be filled into the container can.

The exemplary optional measurement of the density and / or the temperature of the liquid product to be filled before, during or during the filling process can take place inline, as well as continuously or discontinuously, e.g. cycle-related, while the filling device or the filling system is in operation.

Said exemplary relationship of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled can take into account, among other things, the specific density of the liquid product to be filled at a predetermined reference temperature.

Said exemplary predetermined reference temperature can be, for example, a legally prescribed or an operationally required norm or standard temperature, for example a standard room temperature, for example about 20 ° C., at which the product is to be stored or sold. Said reference temperature can therefore be, for example, a prescribed reference temperature for checking a fill quantity requirement.

Said exemplary relationship of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled can be determined empirically and / or theoretically.

For example, a relationship between density and temperature of the product can be derived or created from a large number of laboratory measurements of the density of a given product for a large number of different temperatures of the product, in the form of a table and / or a profile or a curve, for example a Density profile or a density curve of the product, which can describe the density of the product as a function of the temperature of the product.

Said exemplary relationship between density and temperature of the product can be normalized, for example, by a / the specific density of the product at / at said exemplary predetermined reference temperature.

Said derived exemplary density curve based on laboratory measurements can be modeled mathematically, for example on the basis of a polynomial formula to create an optimal (best-fit) model or a formula based on it at a measured temperature of the product, e.g. a filling temperature, the density of the product can be determined or calculated.

Alternatively or additionally, for example, the relationship between the density of the product as a function of the temperature of the product can also be derived and described solely or essentially by theoretical physical considerations. This exemplary relationship, derived from theoretical considerations, between the density of the product as a function of the temperature of the product can then in turn, for example, be compared with laboratory data and, if necessary, adjusted or calibrated.

Said exemplary empirically and / or theoretically determined relationship of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled can be described, for example, by means of at least one approximation equation or an approximation formula.

For example, said empirically and / or theoretically determined relationship of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled can be described with an approximation formula in the form of at least one polynomial formula, for example a polynomial formula of the first or higher degree.

The exemplary determination of the relationship between the density of a liquid product to be filled as a function of the temperature of the liquid product to be filled can be carried out for a large number of different product groups or different product types, said different product types including, for example, at least one of the following product types: aqueous solutions and / or Dispersions, oils, free-flowing fats, products with a predominant oil or fat content, oil-in-water emulsions, alcohol-in-water solutions.

To calculate or determine the density of the liquid product to be filled depending on the temperature of the liquid product to be filled, the following exemplary approximation equations or approximation formulas or polynomial formulas or references / algorithms for the relationship of the density of the liquid product to be filled depending on the temperature of the Liquid product to be filled can be used for different product groups or different product types.

For products that can be described as aqueous solutions, ie as a solution of a hydrophilic substance in water, and / or for products that can be described as dispersions, the following approximation formula (s) can be used, for example. $$\mathrm{\rho product}\left(\mathrm{T}\right)=\mathrm{\rho product}\left({\mathrm{T}}_{\mathrm{REF}}\right)/\left(\mathrm{\rho product}\left({\mathrm{T}}_{\mathrm{REF}}\right)+\mathrm{\rho water}\left({\mathrm{T}}_{\mathrm{REF}}\right)/\mathrm{\rho water}\left({\mathrm{T}}_{\mathrm{REF}}\right)\times \mathrm{1}-\mathrm{\rho product}\left({\mathrm{T}}_{\mathrm{REF}}\right)\right)$$

Here, pProduct (T) is the density of the product as a function of the temperature T of the product, ie pProduct (T) can be interpreted as the density curve of the product as a function of the temperature of the product, and dProduct (T _REF ) is the relative or specific density of the Product at a predetermined reference _temperature T REF, for example a legal one prescribed or an operational norm or standard temperature or reference temperature, e.g. T _REF = 20 ° C, to check a fill quantity requirement, and dWater (T _REF ) is the relative or specific density of water at said reference _{temperature T REF} , and pWater (T) is the density of water as a function of the temperature T of the water. The temperature T can for example be understood as the filling temperature.

The exemplary approximation formula (1) thus relates a measured specific or relative density of the product at a reference temperature with the density of water at the reference _temperature T REF and with the density of water at a filling temperature T in relation to the density of the product at a Filling temperature T.

For example, the temperature-dependent density of water, pwater (T), under normal pressure conditions, ie at a pressure equal to or close to 1013 mbar (1 atm), can be determined as a function of the temperature T using the following approximation equation. $$\mathrm{\rho water}\left(\mathrm{T}\right)\approx \mathrm{999},\mathrm{972}-\mathrm{7th}\times {\mathrm{10}}^{-\mathrm{3}}\times {\left(\mathrm{T}-\mathrm{4th}\right)}^{\mathrm{2}}$$

Based on comparisons between empirically measured density values in the laboratory of products with density values calculated according to the approximation formulas (1) and (2), it has surprisingly been shown that the approximation formula (1) is a good and sufficiently precise description for temperature-dependent changes in density of the Product represents.

Alternatively or additionally, the following approximation formula or the following relationship can be used to calculate or determine the density of the liquid product to be filled, pproduct (T), depending on the temperature T of the liquid product to be filled. $$\mathrm{\rho product}\left(\mathrm{T}\right)=\mathrm{\rho water}\left(\mathrm{T}\right)+\left(\mathrm{\rho product}\left({\mathrm{T}}_{\mathrm{REF}}\right)-\mathrm{\rho water}\left({\mathrm{T}}_{\mathrm{REF}}\right)\right)$$

Here again, as introduced above, the expression pproduct (T _REF ) denotes the specific density of the product at a given reference _{temperature T REF} , for example a statutory or operational norm or standard temperature or reference temperature, e.g. T _REF = 20 ° C, for testing a fill quantity requirement, and the expression pwater (T _REF ) denotes the specific density of water at said reference _{temperature T REF} .

The example approximation formula (3) assumes, for the sake of simplicity, that the product density as a function of the temperature is the sum of the water density as a function of the temperature and the difference between the specific product density and the water density at the reference temperature can be displayed.

The exemplary possible approximation formula (3) also provides sufficiently precise density values for a product of the type mentioned above, as was also confirmed by numerous laboratory measurements and comparisons. Sufficiently precise means, for example, +/- 10%, preferably +/- 5%.

For products that can be described as oils, flowable fats, products with a predominant oil or fat content, oil-in-water emulsions (e.g. mayonnaise), the following approximate formula can be used as the basis for the relationship between the density of the liquid product to be filled depending on the temperature of the liquid product to be filled. $$\mathrm{\Delta }\mathit{V}=V_a\cdot \lambda \cdot \mathrm{\Delta }\mathit{T}$$

Here, ΔV is the temperature-dependent differential volume of the product, V _{a is} the initial volume or reference volume of the product, λ is the product-specific coefficient of thermal expansion and ΔT is the temperature difference in relation to the initial temperature or a reference temperature.

The result is resolved according to the specific densities $$\mathrm{\rho product}\left(\mathrm{T}\right)={\mathrm{\rho T}}_{\mathrm{REF}}/(\mathrm{1}+\mathrm{\lambda }\left(\mathrm{T}-{\mathrm{T}}_{\mathrm{REF}}\right)$$

Here ρT _{REF is} the specific density of the oil at the reference _{temperature T REF} , λ the product-specific coefficient of thermal expansion, T the current product temperature and pProduct (T) the calculated temperature-dependent specific density of the oil

For products that can be described as alcohol-in-water solutions, it was found that it is easier and more advantageous to empirically measure the relationship between the density of a liquid product to be filled as a function of the temperature of the liquid product to be filled, using laboratory measurements , and based on the measurements, said relationship or a density curve by modeling the data of the measurements to be determined, for example by determining the model that best fits the data of the laboratory measurements, wherein the model can be based on a polynomial formula, for example.

The possible specific relationships described above by way of example between the density of a liquid product to be filled depending on the temperature of the liquid product to be filled for a large number of different product types or the specific density curves can then, for example, be stored in a local data or working memory of an intelligent electronic controller of a device can be stored in a container for filling liquid products.

It is of course also conceivable that the said exemplary intelligent electronic control has access to certain / calculated relationships between the density of a liquid product to be filled depending on the temperature of the liquid product to be filled for a large number of different product types or to the specific density curves via an external data memory .

The exemplary intelligent electronic control can also be in communication with at least one measuring sensor system of the device for filling liquid products and receive a large number of data, parameters and parameter values via said exemplary measuring sensor system, in particular, for example, data or values for temperature and / or density of the product in different parts or components of the filling device.

Due to the relationships between the density of a liquid product to be filled as a function of the temperature of the liquid product to be filled for a large number of different product types or because of the specific density curves and because of the data obtained from the measuring sensors of the device for filling liquid products, for example the The temperature of the product in front of or at the filling system, e.g. at the filling element or at the filling valve, can then be used by the exemplary intelligent electronic control, for example via a digital processor, e.g. a central processing unit (CPU), which can calculate the product quantity to be filled into a container, for example. for filling the product quantity that corresponds to a / the desired product quantity at a / the specified reference temperature or the / a specified reference temperature to meet a specified filling quantity requirement.

An exemplary device for filling liquid products into a container can include dosing means via which the calculated amount of the liquid product to be filled can be dosed for filling, in particular for gravimetric and / or volumetric dosing or filling, in which the calculated amount to be filled Amount of the liquid product to be filled can be measured, dosed and filled in mass units (e.g. in kilograms, kg, grams, g, or milligrams, mg) and / or volume units (e.g. in liters, I or milliliters, ml).

The exemplary filling system or filling machine 1 can be designed as a rotating filling machine on the circumference of which a plurality of filling elements / filling valves 2 can be attached.

The exemplary filling vessel / product tank / product storage tank 101 can be filled with a product 102 to be filled via an exemplary product line 7 and a product feed 103.

The device 100 can also have at least one measuring sensor system 10, which can have numerous different measuring devices / measuring sensors 3, 4, 5, 8, and can be configured to measure the temperature and / or the density of the liquid product 102 to be filled during the filling process, for example the temperature of the product to be filled liquid product 102 in the product storage tank 101 and / or in a filling element / filling valve 2.

The device 100 can also have an electronic control 6 as described above, which via data lines and / or signal lines 9, identified here by way of example by a dot-dash designation, for the exchange or transmission of data and commands in communication with the at least one measuring sensor system 10 or the measuring devices / measuring sensors 3, 4, 5, 8 can stand.

The exemplary electronic control 6 can be configured to control the device or the filling system 1 for filling the liquid product into a container on the basis of a relationship, as described above, between the density of the liquid product 102 to be filled as a function of the measurement sensors 10, 3, 4, 5, 8 measured temperature of the liquid product 102 to be filled.

For this purpose, the exemplary electronic control 6 can have a computer processor.

As described above, the electronic control 6 can access a data memory in which empirically and / or theoretically certain relationships of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled can be stored, for example in the form of tables and / or Density curves, whereby, for example, as described above, the relationships between the density of the liquid product to be filled as a function of the temperature or the density curves can be described in the form of approximate equations.

The electronic control 6 can also be configured to meter or fill, for example gravimetric or volumetric filling, of the liquid product using the calculated amount of the liquid product to be filled into the container via the filling system / the filler / the filler 1 or via the filling elements / filling valves 2.

In the following, a possible specific arrangement / design of the measuring sensor system 10 or the measuring devices or measuring sensors 3, 4, 5, 8 will be described by way of example.

For example, each of the filling members / filling valves 2 of the filling machine 1 can be equipped with a volume or mass measuring device 3.

A level probe 4 and a temperature transmitter / temperature sensor 5 for detecting the product temperature can be integrated in the product storage tank 101 of the filling machine 1.

A measuring device 8 can be integrated in the product line 7 to the product storage tank 101 of the filling machine 1, which can transmit to the controller 6, for example, the parameters of product density, temperature and possibly also the flow rate, e.g. B. via a mass flow meter, and wherein the measuring device 8 can transmit the measured values to the controller 6 inline and in real time.

The filling quantity in mass or volume units can be determined by the controller 6 based on the (specific or relative) density determined by the measuring device 8 in the product line 7 for the current product temperature, as described above, on the basis of calculations of mathematical approximation equations for density determination become.

For example, after a longer standstill of the filling machine, the product in the product line 7 and in the product holding tank 101 can cool down at different rates and correspondingly Have density differences. These differences in density can be detected and taken into account when calculating the amount of product to be filled.

The Fig. 2 describes by way of example and schematically a possible further device 200 for filling liquid or flowable products into a container, which analogously to device 100, for example, is a filling system / a filling machine / a filler / a filler 1 with at least one filling vessel / product holding tank 101 and with at least one filling element / Filling valve 2 (shown here by way of example with two filling organs / filling valves).

The exemplary filling system or filling machine 1 can be designed as a rotating filling machine, analogously to the device 100, on the circumference of which a plurality of filling elements / filling valves 2 can be attached.

The exemplary filling vessel / product tank / product holding tank 101 can be filled with a product 102 to be filled, analogously to the device 100, via an exemplary product line 7 and a product feed 103.

The device 200 can also have an electronic controller 6, as described above, which via data lines and / or signal lines 9, identified here by way of example by a dot-dash designation, for the exchange or transmission of data and commands in communication with the at least one measuring sensor system 10 or the measuring devices / measuring sensors 3, 4, 5, 9 can stand.

The exemplary electronic control 6 can be configured to control the device or the filling system 1 for filling the liquid product into a container on the basis of a relationship, as described above, between the density of the liquid product 102 to be filled as a function of the measurement sensors 10, 3, 4, 5, 9 measured temperature of the liquid product 102 to be filled.

In particular, the exemplary electronic control 6, as described above, can calculate the amount to be filled into the container, e.g. a weight amount and / or a volume amount, of the liquid product to be filled on the basis of the measurement sensor system 10 or the measurement devices / measurement sensors 3 , 4, 5, 6, 9 measured temperature of the liquid product 102 to be filled during the filling process and taking into account the specific relationship between the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled. For this purpose, the exemplary electronic control 6 of the device 200 can have a computer processor.

As described above, the electronic control 6 can access a data memory in which empirically and / or theoretically certain relationships of the density of the liquid product to be filled as a function of the temperature of the liquid product to be filled can be stored, for example in the form of tables and / or Density curves, whereby, for example, as described above, the relationships between the density of the liquid product to be filled as a function of the temperature or the density curves can be described in the form of approximate equations.

The electronic control 6 can also be configured to meter or fill, for example gravimetric or volumetric filling, of the liquid product via the calculated amount of the liquid product to be filled into the container via the filling system / filler / filler 1 or via the filling elements / filling valves 2 to be controlled.

In contrast to device 100, however, there are no measuring devices in device 200 in the product line.

Instead, for example, product-specific data such as B. (specific or relative) density and the product at a reference temperature in the process side of the product preparation by suitable inline measuring devices 11, or in the laboratory 12 per product batch can be determined and either the controller 6 by signal exchange, or by input by the operator the control 6 are transmitted.

Analogously to the device 100 and as described above, in the device 200 using the specific data of the specific or relative density of the product at a reference temperature, that is, using a specific relationship between the density of a liquid product to be filled depending on the temperature, together with the z. B. in at least one filling element 2 by an integrated temperature sensor 5 determined actual temperature of the product and, as described above, using various mathematical algorithms (depending on the product type) the temperature-dependent density of the product in the controller 6 are calculated.

On the basis of this calculated / determined density, the electronic control can in turn calculate and set the target volume or target mass for the product to be filled, so that the filling quantities can be adjusted again based on a specified reference temperature.

This exemplary method can be particularly suitable for batch production, since it has been found that the specific density of the product is relatively constant within a batch and can only vary as a result of temperature changes.
