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.

Known fishing vessels of the "trawler" type, which are, in their dimensions, and / or their general layout, and / or their purpose, analogues of the claimed specialized trawler (trawler-factory with an enzymatic method for processing aquatic biological resources), for example: "Fishing trawler, freezing and canning (supertrailer ) type "Pulkovo Meridian", 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, frosts of processed or unbroken fish, processing of non-food by-catch and fish processing waste into 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 "Reference book of typical vessels" Fleet of the fishing industry ", Edition 3, M, "Transport", 1990, p. 34-37).

The disadvantage of the analogue is that it does not fully comply with modern requirements regarding the use of a vessel of this class for the extraction of mass species of aquatic biological resources (FBG), primarily small mesopelagic fish and krill due to the impossibility of their efficient and waste-free processing by traditional methods in fishing conditions.

The closest technical solution to the declared for its purpose, adopted for the closest analogue (prototype) of the utility model, is "Mining vessel with an enzymatic method for processing hydrobionts" (see the description of the patent of the Russian Federation No. 49512 for utility model, priority from 2005.07.08 ,, class B63B 35/24, 38/00, publ. 2005.11.27) containing a hull with a cargo hold and a machine-boiler compartment, a propulsion and steering complex, field equipment and technological equipment made in the form of a single ship technological complex for the production of of a dry fish hydrolyzate, which (complex) includes a site for the reception and temporary storage of aquatic biological resources, a site for the production of a protein hydrolyzate from aquatic biological resources, a site for the production of fish oil and a site for the disposal of solid residues, such as bone residue and / or shell, and a site for the production of protein hydrolyzate contains interconnected device for the fermentation of aquatic biological resources, a device for dividing products into fractions, devices for drying the final product, and is intended one (vessel) for the enzymatic processing of FBG, mainly mesopelagic fish and krill.

The disadvantage of the closest analogue (prototype) is that the ship technological complex during operation has insufficient loading due to uneven filling of the fermentation device, which, ultimately, limits the production capabilities of the technological complex as a whole.

The proposed utility model is aimed at eliminating the disadvantage of the closest prototype analogue, including ensuring a more uniform technological loading of the ship processing complex during the processing in ship conditions of the most massive FBG species (small mesopelagic fish and krill) while improving the crew's production conditions in remote fishing conditions.

This is achieved by the fact that at the proposed trawler plant with an enzymatic method of processing FBG, comprising a hull with a cargo hold, a machine-boiler compartment and a propulsion-steering complex, fishing and technological equipment, and the technological equipment is made in the form of a single ship technological complex for enzymatic processing FBG, including a site for the reception and temporary storage of aquatic biological resources, a site for the production of protein hydrolyzate from FBG, a site for the production of fish oil and ok disposal of solid residues, such as bone residue and / or shell, while the protein hydrolyzate production section contains interconnected devices for FBG fermentation, a device for dividing products into fractions, devices for drying the final product, mainly from mesopelagic fish and krill, unlike from the closest analogue - the prototype, at the site of reception and temporary storage of aquatic biological resources, at least one storage hopper is placed, and at the site of production of protein hydrolyzate ust at least one bunker metering device connected to the storage bunker has been renewed, the bunker metering device being connected to a device for fermenting aquatic biological resources and having a volume not exceeding the volume of said apparatus for fermenting aquatic biological resources.

In addition, the storage hopper is configured to receive and cool - at least half the daily output of a device for fermenting aquatic biological resources and is equipped with cooling and circulating cooling water and vacuum pumping of aquatic biological resources.

One of the best options is a design in which the battery-hopper and the metering hopper are made sectional, and at least one chopper is installed between them.

In the conditions of mass production, the manufacture of the claimed design of the trawler plant with the enzymatic method of processing FBG is carried out using materials, equipment and technologies used in shipbuilding.

The essence of the utility model is illustrated by a drawing, in Fig. 1 of which a schematic longitudinal section of a trawler plant with an enzymatic method for processing FBG with "functionally" designated basic elements of its construction is schematically shown, in Fig. 2, a site for the production of a fish protein hydrolyzate (enlarged).

An example of a specific implementation of the claimed utility model is the development of one of the options for a trawler plant with an enzymatic method of processing FBG (mesopelagic fish and krill), performed by Giprorybflot OJSC in support of the technical requirements developed by it for a vessel of this type.

A trawler plant with an enzymatic method of processing FBG contains a building 1 with a machine-boiler compartment 2, a stern slip (not shown in the drawing), a propulsion and steering complex 3, in the middle of which (the case), refrigerated cargo holds 4 are provided for dry products 5 fat storage tanks.

The technological complex of the trawler plant is designed for processing FBG (small mesopelagic fish or krill) into a protein hydrolyzate, bone residue or shell, fat, and is made up of:

- the reception and temporary storage area of the FBG, including a multi-section storage hopper 6 with a cooling system and cooling water circulation, a vacuum pumping unit for raw materials (vacuum pump), a water separator (not shown in the drawing);

- plot 7 for the production of fish protein hydrolyzate, including interconnected hopper-dispenser 8 (see figure 2), at least one fermenter (device for fermentation of aquatic biological resources) 9 (see figure 2), hydrolyzate purification device: for separating a solid residue (bones, scales or shell), for example, a horizontal sedimentation centrifuge, as well as a device for separating fat, for example, a mud separator (not shown in the drawing);

- section 10 of the drying of the hydrolyzate;

- section 11 utilization of solid residue (bone residue and / or shell) (not shown);

- plot 12 of the production of fat (technical, veterinary or food).

Each of sections 7, 10, 11 and 12 is equipped with the necessary vehicles and devices for packaging and packaging of finished products (not shown in the drawing).

The storage hopper 6 (see figure 2), in one embodiment, mainly when processing mesopelagic fish, is connected to the hopper-dispenser 8 by a pipe 13 through a grinder 14, for example, a knife chopper of the brand "Plasma 10I" (see figure 2) and pipeline 15. In another embodiment, mainly during the processing of krill, the storage hopper 6 is connected directly to the metering hopper 8 by a pipeline (not shown in the drawing). The hopper-dispenser 8 is connected to the fermenter 9 by a pipe 16.

The proposed design of the trawler plant during its operation is used as follows.

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.

Then, krill or fish lifted aboard the trawler plant are placed for cooling and temporary storage in storage hoppers 6. The cooled catch of krill by means of a vacuum pumping unit or otherwise is supplied through a pipeline (not shown) to the metering hopper 8.

Cooled catch of mesopelagic fish through the installation of a vacuum pumping or otherwise fed through a pipe 13 is sent to a chopper 14 (located in section 7), chopping fish, and then through a pipe 15 is pumped to a hopper 8 (placed in section 7), and from it (8) through the pipeline 16 to the fermenter 9 (placed on the plot 7). After loading the fermenter 9 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 piped (not shown) in a piping system into the fermenter 9.

At the end of the fermentation process, the hydrolyzate is deodorized directly in the fermenter 9 by steam skimping and discharged into a receiving tank (not shown in the drawing).

To remove the solid residue (bones, scales or shell), the hydrolyzate is subjected to cleaning in a horizontal precipitation centrifuge (not shown in the drawing), and then to separate the fat in a mud separator (not shown in the drawing).

The solid residue is sent to a disposal line (located in section 11), consisting of interconnected dryers, mills and a block for packaging bone meal (or shell) in bags (placed in section 11, not shown in the drawing).

The fat is sent for cleaning to a fat separator and fortification (located in section 12, not shown in the drawing).

The purified hydrolyzate by means of a pump (not shown in the drawing) enters a vacuum evaporation apparatus (not shown in the drawing), where it is evaporated to a solids content of 15-35%, then it is heated to 70-80 ° C (the hydrolyzate is pasteurized), and then it is dried to a powder state with a moisture content of 5% in a spray dryer (not shown in the drawing), hot air into which (dryer) is supplied through an air duct from an air heater (not shown in the drawing).

The resulting dry hydrolyzate is packaged in bags with polyethylene liners with a capacity of 50 kg and sent to hold 4 for storage.

Calculations show that the production and technological capabilities of a trawler plant with an enzymatic method for processing FBG 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 with respect to all known mining vessels, including trawlers, of the previous construction.
