The utility model relates to the food and fishing industry, and more specifically to equipment designed for processing waste from cutting hydrobionts.

A known installation, which for its purpose is an analogue of the claimed, for example, installation (see the description of the patent of the Russian Federation No. 2023399 for the invention "Installation for the production of dry fish protein concentrate from broth", CL A23L 1/325, publ. 11/30/1994 g .), designed to obtain the finished target product: dry fish protein concentrate from the broth. The specified analogue contains vehicles for feeding the broth, pumps, a storage tank with a heater, a rotary film apparatus connected to a vacuum system equipped with two consumable tanks connected to the output of the rotary film apparatus, a heater and a dryer with a vibro-boiling layer of inert bodies, and also communicated between a plasmolizer, a separator, an additional storage tank with a heater and a rotary film apparatus, a homogenizer located directly in front of the dryer, etc. and this plasmolizer is connected to the exits of the consumable tanks of the main rotary film apparatus, and the vacuum system contains two additional consumable tanks communicated with the output of the additional rotary film apparatus.

The disadvantage of this analogue is its low efficiency when conducting extraction from heterogeneous raw materials (fish waste).

Also known installation, which in its purpose and general layout is an analogue of the claimed, for example, installation (see the description of the patent of the Russian Federation No. 2059390 for the invention "Complex installation for protein concentrate, lipids and chitin from chitin-containing raw materials", class A23L 1 / 33, A23J 1/04, publ. 05/10/1996), intended for the preparation of target products: protein concentrate, lipids and chitin from chitin-containing raw materials. The specified analogue contains a container for preparing a concentrated water-salt solution, a reactor with a stirrer for producing a suspension, a block of electrolyzers divided into cathode and anode chambers, a centrifuge, a separator, a remote suspension heater, a shell washing device, a chitin washing device,

The disadvantage of this analogue is its low efficiency in the processing of fish waste and the increased duration of the process as a whole.

The closest technical solution to the claimed utility model and general layout adopted for the closest analogue (prototype) of the utility model is the installation (see the description of the RF patent No. 88514 for the utility model "Installation for the production of protein concentrate and chitin from chitin-containing fouling", class A23L 1/33, published on November 20, 2009), intended for the preparation of finished target products: protein concentrate and chitin from chitin-containing fouling agents. The specified closest analogue (prototype) contains a container for preparing a concentrated water-salt solution, a reactor with a stirrer for preparing a suspension, a block of electrolyzers divided into cathode and anode chambers, a suspension heater, a centrifuge, a separator, a shell washing device, a chitin washing device, and ultrasonic chamber for fine cleaning of chitin-containing raw materials from foreign objects.

The disadvantage of the closest analogue (prototype) is that it does not fully comply with modern technical requirements for ship installations for the electrochemical processing of waste from cutting hydrobionts, namely, the required level of protein concentrate yield, as well as the significant duration of the process, are not provided.

The proposed utility model is aimed at eliminating the shortcomings of the closest analogue (prototype), including increasing the efficiency of the ship's installation for electrochemical waste processing from cutting hydrobionts by reducing the time of the technological process while expanding its functionality by expanding the range of different types of processed raw materials (processing waste fish, crustacean processing waste, etc.), as well as environmental safety environment, fully meeting all modern technical requirements of international environmental agreements.

This is achieved by the fact that in the design of the proposed ship installation for the electrochemical processing of waste from cutting hydrobionts containing a container for the preparation of a water-salt solution, a block of electrolyzers, each of which is divided into a cathode and anode chamber, a reactor with a stirrer and a heater, in contrast to the analog (prototype), the installation is additionally equipped with at least one tank for grinding waste, as well as at least one separate tank for the target products with a filtration device on inlet, while the heater is placed in the reactor.

One of the most optimal from the point of view of the efficient operation of the ship's installation for the electrochemical processing of waste from cutting hydrobionts during its operation is the option in which it is equipped with an additional capacity for anolyte and an additional capacity for catholyte, with the capacity for the anolyte connected to the anode chamber and the capacity for catholyte is connected to the cathode chamber of each electrolyzer, respectively, and the capacity for catholyte is connected to the reactor.

The essence of the claimed utility model is illustrated by the drawing, in Fig.1 which schematically shows a structural diagram of a ship installation for electrochemical processing of waste from cutting hydrobionts.

An example of a specific implementation of the claimed utility model is one of the design options for a ship installation for the electrochemical processing of waste from cutting hydrobionts, developed by Giprorybflot OJSC.

The shipboard installation for the electrochemical processing of waste from the cutting of hydrobionts contains a container for grinding waste (a raw material shredder) 1, a container for preparing a concentrated water-salt solution 2, connected (2) to the inlet of an electrolytic cell 3, divided into cathode and anode chambers, anolyte 4 capacity connected to the inlet and outlet of the anode chambers of the electrolytic cells 3, the catholyte capacity 5 connected to the outlet of the cathode chambers of the electrolysers 3 and with the inlet of the reactor 6 with a stirrer (not shown). A heater 7 is placed in the reactor. The outlet of the reactor 6 is connected to the input of the filter 8, which is connected to a storage tank 9 (capacity for the target product) for accumulating protein concentrate and a hopper 10 for accumulating mineral residue (capacity for the target product).

All individual devices and types of equipment included in the proposed installation are interconnected hydraulically, for example, by means of the corresponding type of pipelines with manually controlled or automatic valves and pumps (not shown in the drawing).

Ship installation for electrochemical waste processing from cutting hydrobionts works as follows.

To obtain the desired target product - protein concentrate, as well as the mineral residue from the waste from the cutting of hydrobionts, for example, the waste from the cutting of fish is loaded into a container for grinding waste 1. In a container 2, a concentrated water-salt solution is prepared, which (solution) is sent to the electrolyzer block 3, in which (3) produce the time of catholyte to the desired pH value, for example, not less than 12.0. Then the catholyte is sent to the catholyte tank 5, from which (5) the catholyte is sent to the reactor 6 with a stirrer (not shown in the drawing) and a heater 7. From the tank 1, the crushed fish waste (raw materials) are sent to the reactor 6, in which (6) the raw materials are mixed with catholyte and heated with a heater 7 to the required temperature, for example, at least 60 ° C, then the raw materials are held for at least 15 minutes until the protein fraction is completely dissolved (until the protein is completely extracted), then the contents from the reactor 6 are sent to the filter device 8. In the device 8 They add a protein solution, which is sent to the storage tank 9, and the mineral residue is sent to the hopper 10.

The utility model allows to increase the efficiency of the ship's installation by reducing the time of the technological process while expanding its functional capabilities for the processing of waste of hydrobionts, as well as to fulfill the requirements for ensuring environmental safety of the environment.
