Description

The utility model relates to the field of shipbuilding, and more specifically to the construction of specialized fishing (mining) vessels, mainly of the “feed trawler trawler” type, for example, large or medium displacement, equipped with special technological equipment for using the enzymatic method of processing raw materials, as well as holds and tanks for storage of special developed products, and can be used in the design and construction of new types of vessels of the fleet of the fishing industry.

There are known fishing (mining) vessels of the “trawler” type, which, by their dimensions, and / or their general layout, and / or their purpose, are analogues of the claimed specialized fishing vessel, for example: “Large freezing fishing trawler of the Ivan Bochkov type, pr.V-408 (see "Reference vessel of typical vessels" Fleet of the fishing industry ", edition 3, M," Transport ", 1990, pp. 38-41), intended for processing fish into frozen products in a split and undivided form.

The specified vessel is intended for the extraction and processing of traditional pelagic and bottom fish species with or without mechanical cutting and subsequent freezing in freezers and storage of frozen products in refrigerated holds.

The disadvantage of the analogue is the impossibility of its use for mass processing of small hydrobionts with special physico-chemical properties of their living tissue, for example, small mesopelagic fish and krill, excluding their mechanical processing.

The closest technical solution to the declared, according to its purpose, dimensions, design and general layout adopted for the closest analogue (prototype) of the utility model, is "Fishing

freezing and canning trawler (super trawler) of the Pulkovo Meridian type, pr.1288 with a stern slip arrangement, intended for fishing with bottom and deep trawls in remote areas of the World Ocean in the conditions of autonomous or expeditionary fishing, freezing of processed or uncut fish, processing of non-food by-catch and fish processing waste for fodder flour, preparation of canned fish, production of fish oil, storage of products and their delivery to transport vessels or transporting products to the port (see "Ref. reference book of model vessels "Fleet of the fishing industry", edition 3, M, "Transport", 1990, pp. 34-37).

The disadvantage of the closest analogue (prototype) is that it does not fully comply with modern requirements regarding the use of a vessel of this class for the production of mass species of small mesopelagic fish or krill due to the impossibility of their efficient and waste-free processing by traditional methods, as well as insufficient tank capacity for fat produced by catching the most massive mesopelagic fishing objects.

The proposed utility model is aimed at eliminating the shortcomings of the closest prototype analogue, including expanding its production and technological capabilities in relation to the extraction and processing of the most popular and until now unclaimed fishing objects (small mesopelagic fish and krill) while simultaneously obtaining new species from them in ship conditions high-quality products with high cost performance.

At the same time, the task of creating a highly profitable producing vessel with an enzymatic method for processing hydrobionts (catch) was solved, the design features of which, combined with the expanded fishing and production and technological capabilities incorporated in it, allow for stable and high-performance fishing of mass species of mesopelagic fish or krill with simultaneous significant

an increase in the total useful time the vessel was in the field and direct processing on site of all the catch into final products with high consumer properties through the implementation in a ship environment of a non-waste and environmentally friendly production method.

This is achieved by the fact that in the proposed production vessel with an enzymatic method for processing hydrobionts, mainly mesopelagic fish and / or krill, comprising a hull with a cargo hold and tanks for fat, a steering-steering complex, fishing and technological equipment, in contrast to the closest prototype analogue , technological equipment is made in the form of a single ship technological complex for the enzymatic processing of hydrobionts, including a site for the production of fish protein hydrolyzate, current production of fish oil and a site for the disposal of solid residues - bone residue and / or shell, while the site of production of fish protein hydrolyzate contains interconnected device for fermenting fish raw materials and other hydrobionts, a device for dividing products into fractions, devices for evaporation and drying of the final product, and the cargo hold is additionally equipped with ventilated refrigerated rooms for storing dry fish hydrolyzate and solid residues of its processing.

To increase the profitability of a vessel of this type and purpose, one of the most optimal embodiments of the utility model is a design in which the technological complex is made only of interconnected devices for fermentation, separation of products into fractions, evaporation, drying and devices (equipment) for transportation and packaging of final fish products, without placing on the vessel technological lines, devices and equipment for cutting fish, freezers and, accordingly, without troystv and equipment for the disposal of fish processing waste and off-spec materials.

In most cases, the ship's execution of the technological complex, it is additionally equipped with a section for receiving and short-term storage of the catch, including at least one storage hopper.

The storage hopper has a mainly sectional design.

In addition, to achieve these goals, including increasing the total useful time of the vessel in the field, tanks located in the vessel’s hull have an increased capacity and are designed to prevent fat oxidation and are additionally equipped with devices and systems for preventing fat oxidation, for example, an inert storage system gas.

In terms of mass production, the manufacture of the claimed design of the trawler is carried out using materials, equipment and technologies used in shipbuilding.

Each of the above individual functional sections of the complex of enzymatic processing of hydrobionts is additionally equipped with devices for packaging, packaging and transportation of the final product.

The essence of the utility model is illustrated by the drawing, which schematically depicts a longitudinal section of the vessel with the "functionally" designated basic structural elements.

An example of a specific implementation of the claimed utility model is the preliminary study of one of the options for a producing vessel with an enzymatic method for processing hydrobionts (mesopelagic fish or krill), carried out by Giprorybflot FSUE in support of the preliminary technical requirements developed by it for such a vessel in which (development) was first formulated new technical solutions, which, in turn, are the essence of the basic scientific and technical concept underlying the creation of new non-traditional types of mining

special purpose ships and embodied in the proposed utility model.

A production vessel with an enzymatic method for processing hydrobionts comprises a hull 1 with an engine room 2, a stern slip (not shown in the drawing), a propulsion and steering complex 3, in the middle of which (the hull) a refrigerated cargo hold 4 is provided for dry products, tanks for storage of fat 5, a technological complex made only as a part of interconnected devices for fermentation, separation of products into fractions, evaporation, drying (not shown in the drawing), devices for transportation and packaging and final fish (not shown), a temporary storage area of aquatic organisms, comprising a hopper 6 battery.

The fishing device of the vessel consists of two trawls with two autonomous trawl tracks provided, each of which allows to carry out all fishing operations without prejudice to work with the second trawl, while a slurry pipe and water separator can be provided from which the catch is pumped from the trawl by a fish pump and transported fish bins; fish pumps are located on-board in "pockets" in the area of the aft end of the vessel.

Work with the trawl on its descent, raising and casting of the catch is carried out in the usual way in the usual sequence, while in the case of a large catch, the latter is poured using a fish pump, and small catches are lifted along the slip and poured in the usual way.

The technological complex of the vessel is designed for processing small mesopelagic fish or krill into a protein hydrolyzate, bone residue or shell, fat.

In general, the technological complex of the vessel includes:

- a site for receiving and temporary storage of fish or krill as part of a four-section bunker-accumulator below deck 6 with a cooling system

and circulation of cooling water, vacuum pumping units for the production of hydrolysates, a water separator (not shown in the drawing);

- site for the production of fish protein hydrolyzate 7 in two or three lines (not shown in the drawing);

- site utilization of solid residue (bone residue and / or shell) 8;

- fat production site (technical, veterinary or food) 9.

Each of sections 7, 8 or 9 is equipped with the necessary vehicles and devices for packaging and packaging of finished products (not shown in the drawing).

The proposed design of the producing vessel during its practical operation is used as follows.

Fish or krill taken up on board the vessel are placed for cooling and temporary storage in the below-deck storage silos 6. The cooled catch by vacuum pumping or otherwise is fed to the slurry piping or conveyors, the main stream is directed to the fish choppers (located in section 7), which chop the fish, and pumped into the hopper-dispenser, and from it to the fermenter (placed on plot 7).

Krill goes directly to the metering hopper, bypassing the chopper from deck drawers (not shown in the drawing).

After loading the fermenter and diluting with water, stirring and heating are turned on. Upon reaching the set temperature, an enzyme is added, storage is carried out by means of a specially provided container (not shown in the drawing). The enzyme is prepared in the form of a solution in a special room and is pipetted into the fermenter through a piping system.

At the end of the fermentation process, the hydrolyzate is deodorized directly in the fermenter by steam boiling and discharged into a receiving tank (not shown in the drawing).

To remove solid residue (bone, scales or shell), the hydrolyzate is subjected to cleaning in a horizontal precipitation centrifuge (located in section 8), and then to separate the fat in a mud separator (located in section 9).

The solid residue is sent to a recycling line, which consists of interconnected dryers, mills and a block for the packaging of bone meal (or shell) in bags (placed in section 8, not shown in the drawing).

Fat is sent for cleaning to a fat separator and fortification (located in section 9).

The purified hydrolyzate is pumped to a vacuum evaporator, where it is evaporated to a dry matter content of 15-35%, then heated to 70-80 ° C, and then dried to a powder state with a moisture content of 5% and sent to the hold, where it is packaged in bags with polyethylene liners with a capacity of 50 kg (equipment is located on site 9).

The calculation shows that the fishing and production and technological capabilities of a producing vessel with an enzymatic method for processing hydrobionts of the proposed design for pelagic fishing of mesopelagic fish or krill with the subsequent waste-free processing of all catch into dry hydrolysates, solid residue and fat exceed the level of its analogues, including in relation to all known mining vessels, including trawlers, of the previous construction.
