Description
Technical Field
The invention belongs to the technical field of beverage preparation, and particularly relates to a portable quantitative drip filtration extraction device and method for preparing a beverage.
Background
In a home scenario, the method for making solid beverage (coffee, milk powder, tea, etc.) into beverage generally comprises the following steps: instant process, follicular process and cooking process. The instant dissolving method features that the solid hard material becomes the beverage component as much as possible, and is dissolved in water to form solution or suspension, and the powder or tablet is mixed with water to prepare the instant beverage. The key reason for the adoption of the filtering method is that some solid beverage residues cannot be part of the beverage, and a filtering device is needed to separate the solid beverage residues, so that the obtained solid extract is an effective component of the beverage. The cooking method comprises two characteristics of instant dissolution and filtering soaking, and is characterized in that the cooking vessel is used for heating or controlling the temperature of water, so that the cooking method is favorable for more sufficient dissolution and extraction, and the operation of 'tea soup separation' is judged according to the requirement of beverage preparation after dissolution.
The three solid beverage preparation methods have advantages and disadvantages, the instant method has relatively simple requirements on appliances, and is suitable for brewing in most scenes, however, because the instant solid beverage is prepared by deep processing of food, the addition of raw materials other than raw food materials is not increased in the processing process, and even if the additives are harmless to health, the additives deviate from the original flavor of the beverage. The cooking method has complex requirements on the appliances, and is inconvenient to carry and prepare quickly. Most of the current methods for brewing also require a support for the apparatus such as a filter device, and the difficulty of brewing beverages is how to control the concentration of the solution.
Generally, the filtering method is divided into a leaching type and a drip-filtering type, and patent 201172518Y discloses a filtering type coffee bag device, which is a bag device with a hanging ring, and has a simple structure, and only has the purpose of filtering filter residues, and can not control the soaking time and the soaking water quantity, so that the taste of beverages such as coffee, tea and the like which are filtered out can not be well controlled. Leaching requires soaking for a certain time at a certain water temperature to control the solution concentration, so a timer is needed to assist the soaking. The preparation method is stable in the scenes of specially making beverages in milk tea shops and the like, such as a disclosed patent 203424702U and a filtering foam coffee pot, is a filtering foam device which is complex to operate and is relatively special, but is often too thick or too thin in the ordinary home scenes because of not paying attention to control time. The drip filtration method is characterized in that under the action of natural gravity, water with a certain water temperature is passed through a filtering device for holding solids to be extracted, so as to obtain an extraction solution, and the main factor of controlling the solution concentration is the volume of the extraction solution. Because extraction is a time-continuous or piecewise continuous process, the solution concentration is typically controlled in such a way that the extraction cut-off point is controlled (i.e., the extraction is turned off at some point) to obtain the desired volume of solution. It is common practice at present to indicate that the cut-off point is reached by marking a scale on the receiving vessel or weighing the amount of water to be injected with an electronic scale. The graduated method, although allowing the precise determination of the solution volume, requires that the cup material be transparent, otherwise not suitable for viewing; the weighing method also allows precise control of the amount of water injected, but eventually there is a portion of water that remains in the solid material to be extracted, which also has some tolerance.

As shown in fig. 5, ice cubes 10 may be placed under the cup 1 in advance.
A portable quantitative drip extraction method of a brewed beverage based on a portable quantitative drip extraction device of the brewed beverage, comprising: according to the preparation requirements of different prepared beverages, filter bases 3 with different sizes are designed and clamped on the inner wall of the cup body 1, so that the volume of a nominal volume cavity formed by the filter base 3, the side wall of the cup body 1 and the bottom of the cup body 1 is consistent with the volume requirement of a brewing solution of the required prepared beverage.
When the beverage is required to be brewed and extracted, a user needs to operate to open the cup cover 5, take out the brewing filter container 2, uncover the plastic sealing films 4 at the two ends, install a base with nominal quantitative amount at the bottom, empty the rest ingredients in the cup, and put the base in the cup horizontally. Since a pre-calculated and machined base of fixed radius will clamp the whole filter device at a certain height of the cup 1, the space formed by the height and the lower part of the cup 1 is the nominal capacity of the base. At this time, water of a proper temperature is introduced into the filtering container 2 from above, and the extract flows into the space below the transparent base through the filtering means. As the extract increases, the page will float to the level of the transparent base and spill out of the base aperture, taking care to remove the base and filter from the cup when just flush with the base, cutting off the extraction. This gives a nominal volume of extract which, in combination with other ingredients, can be used to prepare a double tasty beverage.
As shown in fig. 7, a cup body 1 is provided, the inner diameter of the bottom of the cup is R1, the inner diameter of the cup mouth is R2, the oblique angle between the wall of the cup and the vertical direction is delta (delta > 0), and the height in the cup is H; a filtering container 2 is a cylinder (table), and the bottom diameter R is not more than the radius R of the cup bottom; the length is not more than H; one end (upper end) of the filter is provided with an opening for water injection, and the other end (lower end) is provided with a filter screen or a filter material, so that extraction liquid can be separated from solid particles through the filter screen or the filter material; the filter base 3 is a circular ring sheet, the hollowed-out circular inner diameter R1 is equal to the bottom radius R of the filter container 2, the filter container 2 can be positively matched with a central circular hole of the base, the outer circular radius of the base is R2, and R2 is larger than the inner diameter R1 of the cup bottom and smaller than the inner diameter R2 of the cup mouth. The annular surface of the circular ring is hollowed with a plurality of round holes, liquid can pass through, and the nominal volume of the solution is printed on the circular ring of the base. The two plastic packaging films 4 seal the two ends of the filter screen and the opening of the filter screen, so that the substances to be extracted in the extraction container are guaranteed and kept fresh. The radius of one cup cover 5 is R2, the cup cover 5 can be just covered on the cup opening of the cup body 1, and the cup cover 5 is provided with a drinking mouth, so that the cup cover can be covered to prevent spilling and can be directly drunk. Other ingredient packages 6 may be used as other ingredients to complete the preparation of the beverage.
The principle of the method and the device for quantifying the extraction liquid is that the volume of the extraction liquid is measured by a cavity formed by the plane of the filter base 3, the annular curved surface of the cup wall and the plane of the cup bottom. The inner diameter R1 of the bottom of the cup, the bevel angle delta of the wall of the cup, the radius of the filter base 3 is R2, and the volume of the cavity is as follows:the volume V obtained with this principle is taken as nominal volume of the filter base 3.
In order to increase the portability of the device, these components are designed in such a way that: the filtering container 2, the filtering base has been preserved and sealed with the plastic film 4 and is waited the extraction raw materials, other batching package 6, it is according to the design processing size requirement, can seal in the cavity between bowl cover 5 and cup 1 with bowl cover 5 from top to bottom, filtering base, filter and batching package 6 form cup 1's equipment order, in order to carry wholly.
In order to facilitate the control of the extraction cut-off point and the quantitative measurement of the volume of the solution by a user, the method and the device are realized in the following way: the filter base 3 can adopt the parameter combination for determining different R1, R2 and delta to obtain the required cup-shaped appearance and the extraction solution volume in the method for controlling the solution volume, and the volume is marked on the filter base 3. The control method for interrupting the extraction is that when the solution level visually seen through the transparent material is about to contact with the filter base 3 along with the increase of the volume of the extraction liquid and just overflows from the small holes of the base, the time for ending the extraction is the moment. It is only necessary to remove the entire filter holder 2 and filter base 3 from the bowl 1, the volume of solution remaining in the bowl being the nominal volume of the filter base 3.
In order to obtain a worry device capable of being combined into beverages with different formulas, the combination method is realized in such a way that the plastic sealing films 4 at the upper end and the lower end of the filter container 2 are firstly removed from the filter container 2 and the filter base 3, then the lower end of the filter container 2 and the filter base 3 are assembled into a filter device, and then the base is arranged in the cup body 1 with the lower opening facing upwards.
In order to prepare fancy beverages containing milk, sugar or chocolate and other solid or liquid ingredients, the preparation method of the beverage is realized by the following steps: the ingredient bag 6 can be solid, liquid or sol, and the extraction solution can be added into the ingredient bag 6 when the beverage is prepared, or the ingredient bag 6 can be added first and then extracted by a filtering device. In the second case, the space actually used for drip extraction needs to be added to the volume Vi of the content of the ingredient bag 6 (solids can be converted into volume by weight), so the space V '=v+vi in the cup is needed as a whole, and the values of R1, R2 and δ are chosen with the aim of obtaining V'.
In order to achieve a more diversified appearance of the device and meet the requirements of aesthetic appearance of users, the method has wide support for the appearance of the cup, and as long as the volume of the extraction liquid can be calculated or weighed by taking the cavity formed by the plane of the filter base 3, the annular curved surface of the cup wall and the plane of the cup bottom, the appearance can be designed into a cup in a round table form, but not limited to a cup in a round table form, and the cup with a known volume (the shape can be calculated by a geometric formula or the special shape can be measured) can be combined with the filter base 3.
The device also uses the method of prompting extraction cut-off point and controlling solution capacity to realize the control of solution concentration. The difference in the way of implementing the prior art lies in that the method of determining the volume using the geometric space of the cup and the filter envelope is used to "measure" a fixed volume of solution, the visual phenomenon of filling the overflow aperture with solution is used as a break point cue, and simultaneously, in order to take account of the different volumes of solution to be prepared for different beverages, different filter bases 3 can be pre-processed to change the volume "measured", so that the same cup can be used for preparing various beverages by combining different types and weights of raw materials through different combinations.
In the example of brewing a standard latte coffee using the apparatus and method of the present invention, we first propose a formulation of a latte coffee starting from 12g of coffee beans and 180ml of liquid milk, by extracting 90ml of coffee liquid from 12g of coffee powder using a filter device and mixing with 180ml of milk to form a latte coffee.
According to the principle of the formula and the preparation of the beverage, according to the method of the invention, a device is firstly selected, a 10 ounce cup paper cup is selected, the size of the cup paper cup is 90mm (height), 62mm (caliber of the cup bottom), 72mm (caliber of the cup opening), and the cup wall bevel angle is 3.18 degrees. 12g of cooked Abirac coffee beans are ground into a powder with proper thickness, filled into a cylindrical filter with a radius of 25mm and a height of 50mm, and two ports are closed by a plastic sealing film, one is a filter screen, and the other is a water injection opening. For preparing 90ml of coffee extract, the required radius of the outer circle of the filter is 32.6mm and the inner circle space is 25mm for matching the filter. In addition, 180ml of liquid milk is filled in a milk bag as a single ingredient bag 6, all the components are dispersed in a cup, a cup cover 5 is covered and coated to form a pre-packaged food, and the assembly schematic diagram is shown in figure 5.
When preparing latte coffee, firstly, the envelope and the cup cover 5 are opened, all parts are taken out from the cup, firstly, the upper and lower sealing films 4 of the filter are torn, then, one section of the filter screen is assembled with the filter base 3, and the filter screen is downward placed in the cup, so that the filter is assembled. Then extracting coffee liquid, placing the cup and the filter screen under the hot water port of the water dispenser (the heat preservation temperature is 85-90 ℃ and is proper for extracting coffee), and injecting hot water. The hot water passes through the coffee powder and the filter to dissolve the soluble substances in the coffee, becomes a coffee liquid, is injected into the cavity of the cup bottom, floats upwards along with the increase of the liquid until the water contacts the filter base 3 and just overflows from the small holes of the base, at the moment, the filter is removed from the cup, and the extraction is finished. The final step is to tamper with the ingredient bag 6 (liquid milk) and pour it into a cup to mix with 90ml of coffee extract already obtained, and then to cover the cap 5 to apply a standard brew of espresso.
Here, another "Ice American" procedure is exemplified, in which 12g of coffee powder as given in this example is extracted to obtain 90ml of coffee extract, and 180g of ice cubes 10 are added to obtain coffee. Since the ice cubes 10 used will after melting with hot coffee be folded into a volume of 180ml, in practice the cup will need to have 270ml of extraction space. Still with the 10 oz paper cup described above, it is desirable that the radius of the filter base 3 be selected to be 35.3mm. In fig. 6, a cup of cool American coffee is prepared by placing the solid ingredients in the cup, placing the assembled filter in the mouth of the cup, and extracting in the same manner as described above.
As another example, the method and apparatus of the present invention are equally applicable to a shaped container that is measurable in a space container.
As shown in fig. 6, a "torch cup" is illustrated in the shape of a cylinder (torch handle) 40mm in diameter by 50mm in height, plus a "torch bowl" of 50mm bottom diameter and 100mm top diameter, 30mm in height. The volume of the cylindrical portion was calculated by the geometric principle to be 62.8ml, and the upper bowl-shaped volume was calculated to be 122.5ml. For such a shape, the filter is set to a radius of 18mm and still 50mm high, and can be stored in a cup, if 160ml of American coffee is to be made, a base with a radius of 46.5mm is used, and during the extraction process, after the coffee liquid fills up 62.8ml of the space of the 'torch handle', 97.2ml of the space is obtained in the cavity formed by the 'torch bowl', 160ml of coffee extract is obtained in total, and a cup of American coffee can be made in a special-shaped container by the method of the invention.
Finally, declare again: although the method and apparatus of the present invention have been described by way of three examples, all changes and substitutions that do not depart from the spirit of the invention are intended to be within the scope of the invention as claimed.
