Description

The utility model relates to the fishing industry, namely, equipment for salting small fish and fillets in circulating brine. The device for salting can be used both independently and as part of lines for the production of salted semi-finished products at coastal fish processing enterprises.

A device for salting fish in brine (AS USSR No. 296552, IPC A23b 3/01, application. 07.21.69; publ. 02.03.71), used in smoking production. The device comprises a salt bath, a pump, a nozzle for feeding brine, a device for moving and tilting fish located above the bath, made in the form of kinematically coupled eccentric pairs with mesh scallops (immersors) articulated on them, consisting of rods and mesh frames, mesh brine trap and filter. For the unloading of salted fish, a blade tilter is provided, and for loading fish - a receiving hopper. The drive is mounted on a platform located above the mechanisms.

The disadvantages of this device are the following:

- uneven salting of the fish layer;

- desalination of the upper layer of brine;

- difficulties in unloading the semi-finished product and its promotion along the bath.

Closest to the proposed technical essence is the mechanized bath of the taste ambassador of project 821 (Engineering and Technical Center Rybholodtekhnika, St. Petersburg, 1995). The bathtub is intended for continuous gustatory salting of small fish: herring, smelt, pieces of herring, cod, etc. The bathtub can work either as a separate unit or as part of a line. The main components of the bath

are frame, drive station, plate and scraper conveyors. The bathtub frame is a welded construction made of angle steel sheathed with stainless steel sheets. The drive station is mounted on the bathtub frame, consists of an electric motor, variator and gearbox. The plate conveyor is two traction chains connected by rods. Perforated stainless steel plates are pivotally attached to the bar. The scraper conveyor consists of two chains interconnected by scrapers.

However, this bath is intended only for flavoring salting, the salting time is 5-23 minutes. The resulting salted semi-finished product has a salt content of 1-3%, which is not enough for the preparation of smoked products with a low salt content. In addition, there is a non-uniformity of brine coverage of the lower and upper layers of fish. The top layer of brine is desalinated, as a result, the fish is salted unevenly over the thickness of the layer.

The technical result, which the utility model aims to achieve, consists in eliminating stagnant zones in brine and leveling brine density in the entire working volume of the bath, ensuring uniform salting of fish.

To achieve a technical result in a device for salting small fish and fillets, containing a salt-water bath with a scraper conveyor equipped with scrapers and a mesh conveyor located under the scraper conveyor, a salt-salt filter, a pump unit, a brine recirculation system, a brine recirculation system are provided nozzles for the supply of brine, the latter are located at the same distance from each other and have an exit below the surface of the brine, scrapers of the scraper conveyor are made from bong in the direction of movement of the conveyor. The distance between the nozzles for the supply of brine is 100 mm, the bending of the scrapers of the scraper conveyor is 35 °, and the output

the nozzles for the supply of brine below the surface level of the latter is 30 mm.

Distinctive features of the proposed cantilever bath are the supply of the brine recirculation system with nozzles for supplying the latter, arranged uniformly over the entire bath area at a distance of 100 mm and having an exit below the brine surface by 30 mm, making scrapers of the scraper conveyor with a bend at an angle of 35 in the direction conveyor movement.

Due to the presence of these features in the proposed device there are no stagnant zones in brine and the rate of diffusion of salt into fish is evened over the entire thickness of the salting layer, which ensures uniformity of salting.

The proposed device for salting small fish and fillets is illustrated by the drawings presented in figures 1, 2.

Figure 1 shows the proposed device, side view, figure 2 - the proposed device, top view.

The device contains the following main nodes (1, 2): a reinforced concrete canteen bath 1, a scraper conveyor 2, a drive station 3, a mesh conveyor 4, a pump unit 5 with a brine recirculation system, a salt-salt filter 6. Bath 1, a mesh conveyor 4 and the scraper conveyor 2, as well as the drives of the conveyors 2 and 4 are installed on the frame (not indicated). The mesh conveyor 4 is located under the scraper conveyor 2 (figure 1). The scraper conveyor 2 is equipped with scrapers (not shown) that are bent at an angle of 35 ° in the direction of movement of the conveyor. Through a flange pipe (not shown) to the bath 1 is connected a salt filter 6, a pump unit 5 and a recirculation system, including pipelines with nozzles for supplying brine (not shown). The nozzles for the brine feed are located at the same distance from each other, which is 100 mm. In this case, the nozzles for supplying brine have an output below the brine level by 30 mm.

The salt-filter 6 (figure 2) is a container, inside which there are partitions (not indicated), which serve for coarse and finer cleaning of the saline solution. The salt-solvent filter compartment 6 is designed to load the necessary salt to support the brine.

The operation of the device is as follows.

Fish intended for salting is loaded into the bath 1 on the canvas of the mesh conveyor 4. As the mesh conveyor 4 moves, the fish is between the last and the scraper conveyor 2. Moving the fish along the bath 1 is carried out by a scraper conveyor 2 with scrapers immersed in brine. At the end of the bath 1, the conveyor 2, leaving the bath 1, captures and unloads the fish. The speed of the scraper conveyor 2 is 4 times less than the speed of the mesh conveyor 4, so that the fish is unloaded from the bath evenly, in a small layer. Depending on the type of cutting and the size of the fish, the residence time of raw materials in brine is different and depends on the speed of the mesh conveyor 4. Changing the speed of the conveyors is carried out using a variator (not shown). When lowering the density of brine from the start button, turn on a centrifugal pump (not shown), which circulates brine in a closed system through a layer of salt: filter salt solvent 6 - bath 1 - filter salt solvent 6. From the pumping unit 5 through pipelines through the pipes reinforced brine enters bath 1, irrigating salted fish with a density of 4.2 · 10 ^-4 (m ³ / s) / m ² . This achieves that the conditions for salting the layer of fish in several rows are close to the conditions for salting in the brine of fish located in one row. Upon reaching the desired concentration of brine pump unit is turned off. The operating mode of the device is continuous. The average salinity of the resulting salted fish is 4.5 ± 0.5%. The salty product is of high quality.

The principle of operation of the device is similar to the work of most mechanized salt baths. However, in the proposed device recycle brine system allows you to maintain close to

optimal irrigation density of the product is 4.2 · 10 ^-4 (m ³ / s) / m ³ , which leads to equalization of the brine density throughout the volume of the bath and uniform salting out of the fish layer.

The model is small in size, the salting process is fully mechanized. The device can produce a salty product with a minimum "variegation" ± 0.5% of the salt content in the entire batch of the semi-finished product.

Using the claimed device for salting allows you to get a salty semi-finished product of high quality for the preparation of smoked products with a low salt content from small fish and fillets, ensuring the continuity of the process and high productivity.

The proposed device has the following advantages: high performance with small dimensions, ease of operation and regulation of salting time, low metal consumption, the possibility of using simple automation schemes, uniform salting of fish along the thickness of the layer.

Initial requirements were developed for the proposed device, which were transferred to the STC “Search” for the development of design documentation. The device was manufactured and passed successful industrial tests.
