Description

The utility model relates to equipment for producing protein concentrate from chitney-containing raw materials intended for use in the fishing industry and agriculture.

A known installation for the production of protein concentrate and chitin from crustaceans, containing containers for chemical reagents, reactors with a stirrer, centrifuge, separator and precipitator.

The disadvantages of the known installation are multi-stage and the duration of the process, the duration, the need to use a large number of chemicals and the insufficiently high quality of the resulting products.

The closest in technical essence and the achieved result to the claimed utility model is an integrated installation for producing protein concentrate, lipids and chitin from chitin-containing raw materials (Patent RU 2023399), containing a container connected by pipelines for the preparation of a concentrated aqueous salt solution, a reactor with a stirrer for preparing a suspension, a unit electrolyzers separated by diaphragms into cathode and anode chambers, a suspension heater connected to a block of cathode chambers, a centrifuge communicated with the input of the block of anode chambers and a separator, a device for washing the shell connected to the input of the block of anode chambers, a device for washing chitin, located at the output of the block of anode chambers. In this case, the reactor is connected to the output of the cathode block and the block of anode chambers.

However, the known device when using chitin-containing fouling materials as raw materials having a 5–7% higher chitin content compared to traditional raw materials obtained from crabs does not provide the required level of yield of chitin from chitin-containing raw materials with the retardation of the entire technological process.

The technical result, which is achieved by the claimed utility model, is to increase the efficiency of the device by including in its design an ultrasonic chamber for fine pretreatment of chitin-containing raw materials from fouling by separating them from the substrate on which they develop.

In FIG. schematically shows a plant for producing protein concentrate and chitin from chitin-containing fouling.

The apparatus for producing protein concentrate and chitin from chitin-containing fouling contains an ultrasonic chamber 1 connected by pipelines for fine cleaning of chitin-containing raw materials from foreign objects (for example, synthetic threads of hydrobiotechnical aquaculture structures), a tank 2 for preparing a concentrated aqueous salt solution, a reactor 3 with a stirrer for preparing a suspension is connected to the output of the block 4 of electrolyzers, divided into cathode and anode chambers, a suspension heater 5, connected to a cathode chamber lock, a centrifuge 6 connected to the input of the anode chamber block and the separator 7, a shell washing device 8 connected to the input of the anode chamber block, a chitin washing device 9 located at the output of the anode chamber block.

Installation for producing protein concentrate and chitin from chitin-containing fouling works as follows.

To obtain a protein concentrate, the crushed protein-containing raw material from chitin-containing fouling enters the ultrasonic chamber 1, where it is separated from foreign objects and sent to the reactor 3 with water and concentrated sodium chloride solution supplied from the tank 2, then the suspension enters the cathode chamber of the cell unit 4 where pH adjusted to optimal values, then the suspension is heated in the heater 5 to a temperature of not more than 85 ° C and maintained in it until the protein fraction is completely dissolved, after which blunt centrifuge 6 where deproteinirovanny shell is separated from the solution and the protein solution is supplied to the separator 7 to separate lipids and further neutralization to pH 6-8 to block the anode compartments of cells. Processing in the block of anode and cathode chambers of electrolyzers is carried out simultaneously in countercurrent mode.

To obtain chitin from the deproteinated carapace of chitin-containing fouling, the solid residue from the centrifuge 6 enters the washing device 8, then it is fed to the reactor 3, where it is mixed in a predetermined ratio with water and concentrated electrolyte solution, and fed to the block of anode electrolysis chambers for demineralization. Next, the obtained chitin enters the device 9 for washing.
