Description

one

The invention relates to the fishing industry, namely to devices for salting small herring fish, herring, salmon and small fish.

A device for salting fish in a circulating brine is known, comprising a salting container with horizontal perforated partitions for dividing it into sections and a brine circulation system. The fish is kept for a specified time in each regular section and is successively bypassed from the lower sections to the adjacent upper ones.

However, the main mass of the concentrated brine during circulation passes along the walls of the salt pans, and does not penetrate into the thickness of the fish. Extreme (top and bottom) fish in each layer have more contact with the brine, while in the thicker layer of the fish contact with a smaller amount of brine because the fish layer interferes with the natural circulation of the brine in the intervals of its bubbling. In addition, the penetrating tozluk is delayed in the lumen between the fish, and is absent in the places of their contact. This leads to uneven salting of fish depending on its location in the layer and affects the duration of salting.

The purpose of the invention is to intensify the process and provide a more uniform salting of fish.

5 This goal is achieved by the fact that in a device for salting fish in a circulating brine containing a salient container with horizontal perforated partitions for dividing it into sections and a circulation system of the brine, hollow perforated shells are attached to the underside of the perforated partitions.

Shells have the shape of a truncated cone, prism, or pyramid attached to a large base, or hemisphere, on the perforated partition.

Claims (2)

A device for salting fish in a circulating brine consists of a sectional salted container 1 with perforated partitions 2, a system of circulation of the brine with a bubbler 3 and drain 4 of the irrigated brine and a device for loading and unloading fish (not shown). Hollow perforated housings 5 having perforations 6 are attached to the underside of the perforated partitions 2. The partitions 2 have perforations 7 and 8, and the perforations 8 are located above the cases 5. The latter can be made in the form of truncated cones, prisms or pyramids attached large base to the perforated partition, or hemispheres. The height of the housings 5 may be equal to 3/4 thickness, according to the fish layer, since the lower part of the layer, equal to 1/4 of the height of the fish layer, already has good contact with the brine and does not require additional measures to improve circulation. In the lower part of the salting vessel 1 there is a false perforated bottom 9. The device operates as follows. Tuzluk from the salt concentrator (not shown) is fed to the salting tank 1, partially filling the lower section. Then a layer of fish (500 mm high) is loaded using a conveyor or tray and the lower perforated partition 2 is lowered. The next (upper) section is loaded in the same way: a litter is fed until a cushioning layer is formed in the upper section, then the upper part is lowered. After loading the salting container 1 with fish, the rest of the concentrated brine is fed from the bottom of the salt concentrator. Under the action of buoyancy force, the entire mass of fish fits snugly to the lower surfaces of the perforated partitions 2. The concentrated toilerate supplied from below passes between the fish and enters the perforated shells (Fig. 3). Due to the fact that the total area of the holes 6 on the body is larger than the area of the holes above the body, the barrel, lifting along the forming body, rushes into the perforation 7 of the partition 2 through the fish layer. Due to the different density of the brines, a weakened brine moves out of 9 THANKS of the fish adjacent to the body, upwards, and the concentrated ones - downwards. The dining brine from the salting vessel 1 is transferred by gravity through the drain 4 into the tank of the weakened brine (not shown). The fresh brine is fed every hour. After the salting process is completed, the fish is discharged from the salting container. For this, the partition of the upper section is raised, the litter is fed from the bottom and the fish and the brine are poured out of the salient vessel. Then the partition of the next section rises, and the emerging fish also unloads along with the brine. The unloaded fish with a brine falls on a net conveyor (not shown), is separated from the brine and is fed for further processing, and the brine is returned for cleaning and reuse to the salt concentrator. The use of the device shortens the duration of salting and, as a result of uniform salting of the fish, increases the quality of the final product, especially in smoked and smoked fish. The estimated economic effect from the introduction of the proposed device is about 60 thousand rubles. Claim 1. Arrangement for salting fish in circulating brine, containing a salting container with horizontal perforated partitions to divide it into sections and the circulation system of the brine, characterized in that, in order to intensify the process and ensure a more uniform salting of the fish, to the lower side of the perforated The dividers are attached in a staggered hollow perforated enclosure. 2. A device according to claim 1, characterized in that the bodies are in the shape of a truncated cone, a prism or a pyramid attached to a perforated partition with a large base, or a hemisphere.
