Description

The utility model relates to the field of biotechnology and fish processing, and more specifically to the design of devices (technological lines) for the integrated processing of krill and other crustaceans and the production of protein enzymatic hydrolysates and chitin, and can be used in fish, food and other industries for the production of food products , fodder and therapeutic purposes.

A known line for the production of biocompost from fish processing waste according to the patent of the Russian Federation No. 2111194, class. C05F 9/04, A22C 25/00, publ. 1998.05.20, containing a fish waste shredder, mixer, fermenter, dryer, as well as a device for determining the initial characteristics of shredded fish waste and an organic filler shredder with apparatus for its granulation and drying, designed for processing and disposal of fish waste into an organic fertilizer for rural households.

The disadvantage of this analogue line is the impossibility of its use for the processing of many widespread types of raw materials of marine origin, for example, crustaceans having a hard outer shell in the form of an armor, consisting of calcium and polysaccharide compounds, as well as excessive “saturation” of the line with additional equipment for preliminary grinding of the initial raw materials, for example, several types of grinders, and as a result, its increased cost and inability to use in ship conditions ..

The closest technical solution to the claimed one, taken as the closest analogue to the prototype of the utility model, is a line installed on a production vessel for implementing an enzymatic method for processing hydrobionts, mainly mesopelagic fish and / or krill, according to the RF patent for utility model No. 49512, class. B63B 35/24, 38/00, publ. 2005.11.27, containing interconnected chopper, hopper, fermenter (fermentolysis reactor), a device for separating solid waste, a device for recycling solid waste (as part of the dryer and mill), a grease separator, a vacuum evaporator and a spray dryer. A device for separating solid waste is made in the form of series-connected devices such as a screen and devices such as a suction filter, or a friend filter, or a press filter, and a device for grinding solid waste is in the form of parallel-mounted roller or hammer and finger mills.

The disadvantage of this prototype line is the limited possibilities for its use, including in ship conditions, for processing and obtaining (production) of protein enzymatic hydrolysates from hydrobionts containing solid outer coatings, for example, from krill and other crustaceans having a hard outer shell in the form of a shell, consisting of calcium compounds and polysaccharides, which is mainly due to limited technological capabilities and composition of technological equipment used in the line.

In addition, the disadvantage of the prototype is the almost mandatory use in the composition of the line of devices for preliminary grinding of the feedstock before it is directly loaded into the fermenter, which also limits the possibility of using the line in cramped ship conditions due to its increased weight and size characteristics.

The proposed utility model is aimed at eliminating the disadvantages of the prototype, including, first of all, expanding the production and technological capabilities of the line in relation to the simultaneous receipt, including in ship conditions, of a wider range of finished products and reducing the mass-dimensional characteristics of the line.

At the same time, the task of creating an optimally balanced in terms of its design features and a more compact and economical ship technological line - an interconnected set of equipment that allows in the ship to put into practice the method (ship technology) of complex waste-free processing of krill and other crustaceans and the production of dry protein enzymatic hydrolysates with the simultaneous receipt, including from their waste, of related target products with high consumer properties - chitin.

This is achieved by the fact that in the proposed marine processing line for krill processing, containing interconnected hopper-dispenser of the feedstock, fermenter, devices for separation and disposal of solid waste, a concentrator of liquid enzymatic hydrolyzate and a device for drying the finished fermentolizate, for example a spray dryer, differences from the closest analogue - the prototype, the device for separation and disposal of solid waste is made in the form of a decanter connected at the outlet of the liquid fraction with Tel'nykh set him hub enzymatic hydrolyzate, and the output solid fraction - is further provided with and mounted in series to the reactor followed by decalcification of the shell.

In the general case of shipboard layout, the reactor for decalcifying the shell at the outlet is connected to a chitin separation device, for example, a suction filter, and a chitin drying device, such as a drum dryer or flash dryer, in series.

To implement the final stage of the technological process, the device for drying the finished fermentolizate and the device for drying chitin are connected to devices for separating the dry product from the gaseous coolant, respectively, made, for example, according to the type of cyclones.

All individual devices and types of equipment that make up the proposed line can be interconnected depending on the specific conditions and the processes occurring in them, either mechanically, hydraulically or pneumatically, for example by means of the corresponding type of pipelines.

Storage of the consumable enzyme preparation can be provided through additional equipment of the fermenter with weighing and volumetric dispensers (not shown in the drawing), for example by fixing them directly on its body.

Depending on the conditions of a particular production, the line may be equipped with a receiving and / or receiving and storage hopper for preliminary storage of raw materials installed in front of the metering hopper.

In the General case, the transportation of raw materials is carried out by mechanical means, for example using conveyor belts.

In comparison with the prototype, the pasteurizer of the enzymatic hydrolyzate and the separator-grease separator are excluded from the technological equipment, since krill contains the minimum amount of fat that does not affect the quality of the enzymatic hydrolyzate.

The essence of the utility model is illustrated by the drawing, which shows a schematic diagram of the ship line for the integrated processing of krill and other crustaceans and the production of protein enzymatic hydrolysates with the simultaneous production of chitin.

An example of a specific implementation of the claimed utility model is a ship line containing a feed conveyor 1, a hopper 2 connected to a fermenter (reactor for fermentolysis) 3, a decanter 4 for separating the fermentolizate from the carapace, connected at one outlet to the fermentolizate concentrator 5 and installed followed by a spray dryer 6, and at the other outlet, with a decalcification reactor for the shell 7 and the nutc filter 8 and a chitin dryer 9 installed behind it; a conveyor 10 connecting the hopper (2) to the fermenter (3), and a conveyor 11 connecting the decanter (4) to the shell decalcification reactor (7).

In ship's conditions, the implementation of the method (ship technology) of the processing of krill and other crustaceans with the simultaneous production of protein enzymatic hydrolysates and chitin using the proposed ship technological line is as follows.

Raw materials without preliminary grinding, for example krill through a hopper 2 using a conveyor 10 are fed into the reactor 3 for fermentolysis. Tap water with a mass of 1 \ 5-1 \ 3 of the mass of raw materials - krill is supplied there. By supplying the coolant to the jacket (not shown) of the reactor 3, the mixture is heated to 40-50 ° C. Then, an enzyme preparation, a protease, is introduced into the reactor, for example by means of a doser connected to it. Fermentolysis is carried out with constant stirring for 60-90 minutes.

At the end of the process, actually fermentolysis, the protein hydrolyzate together with the remains of the outer coating (shell) is discharged through the neck of the discharge device to decanter 4, because the raw material is krill or other hydrobionts with a hard outer coating, before being loaded into the fermenter, they are not subjected to traditional preliminary grinding.

Then the hydrolyzate with the help of decanter 4 is fed to the concentrator of the enzymatic hydrolyzate 5 to thicken it to a concentration of solids of at least 15%.

The condensed hydrolyzate is fed to a spray dryer 6 for drying. Drying is carried out at an inlet coolant temperature of 210 ° C and an outlet temperature of 85-90 ° C.

Solid components of the raw material, for example, the shell of krill or other crustaceans, separated on the decanter 4, is fed into the reactor for decalcification of the shell 7.

After decalcification of the shell with dilute hydrochloric acid and washing with tap water in a 3-5-fold volume relative to the mass of the shell, the chitin prepared at this stage through the suction filter 8 is fed to a dryer 9, for example, a drum-type dryer or a flash dryer. Drying is carried out at a temperature of 80-120 ° C for 10-15 minutes.

At the final stage of the technological process, the device for drying the finished fermentolysate 6 and the device for drying chitin 9 are connected to devices (not shown in the drawing) for separating the dry product from the gaseous coolant, respectively, made, for example, according to the type of cyclones (not shown in the drawing).
