FIELD OF THE INVENTION The invention relates to a feed industry industry, namely, devices for the production of fish pellets.

The aim of the invention is to increase the quality of the pellets and the separation of shredding for its further use in the form of small fractions of feed for juvenile fish.

Since granulated feeds with a coating of granules of various compositions that form waterproof films are widely used for feeding fish, granules of various size fractions are needed. For example, starter feeds with a pellet size of 0.1–0.3 mm are used for feeding the fry, 0.3–0.8 mm for fry, etc. In the manufacture of pellets, a crumb is formed, which has dimensions 0 , 1-0.8 mm and using the proposed device can be used for feeding fry and juvenile fish. In addition, the proposed device allows it to be used in the production lines of granulated animal feed, working on waste-free technology to obtain pellets of all the required size fractions.

FIG. 1 shows the device, a general view; 2 is a section A-A in FIG. one; on fig.Z - section bb in figure 1.

The device contains drum 1 mounted obliquely on rollers 2 mounted on frame 3 and driven by rotation of drive 4, device for spraying film-forming substance, devices 5 and 6 for loading and unloading the product, respectively, deflectors 7, automatic control system (not shown) , feed systems of granules and film-forming substances (not shown).

The drum 1 on the loading side is made perforated and has rings 8 with an abrasive (corundum) coating installed inside it with a gap of 3 mm relative to each other.

but also has a drop-like shape, and its surface is coated with an anti-adhesive composition.

5. A device according to claim 1, characterized in that the nozzles in the tray are arranged in several rows, the nozzles of the upper row being installed horizontally, and the nozzles of the next rows so that their axes are tangential to the generator of the fairing.

Under the perforated area of the drum 1, a tray 9 is installed with a fairing 10 and equipment 11, which are connected to the film-forming substance supply system.

E; 1 to provide a finely dispersed fog; a device for spraying a film-forming substance is installed inside the drum coaxially with it,

equipped with a drive 12, giving it a rotation in the direction opposite to the rotation of the drum 1, and made in the form of a hollow shaft 13 with a partition 14, discharge windows 15, while the nozzle 16 (nozzle) is installed on the shaft 13.

In order to provide better forced transportation and movement of the granules during processing inside the drum, besides the deflectors 7, on the shaft 13 are fixed along the helix of the blade 17, the ends of which are attached, are ina with tape 18 made of elastic

material to form a spiral. Tape 18 may be made, for example, from sheet food polyethylene with a thickness of 2-3 mm.

To ensure more uniform

the distribution of granules (crocheting) over the cross section of the upper part of tray 9, as well as more efficient spraying of the film-forming substance and increasing the duration of its contact with the product, the fairing 10 is mounted on the joint 9

(Fig. 3), and the nozzles 11 in the tray 9 are arranged in several rows, with this, the nozzles of the upper row are installed horizontally, and the subsequent so that their axes are directed along the tangential to the forming fairing 10.

In order to preserve the passage area of the cross section of tray 9 and to avoid product lag in the tray, the fairing 10 has a drop-like shape. To prevent scale on the surface of the spinner 10 of the film-forming substance and the granules, its surface is coated with an anti-adhesive composition.

To unload the granules treated with the film-forming substance, the drum 1 is equipped with discharge ports 20, made with a diameter of at least 8 mm. A device 6 for unloading finished (processed) granules is located under windows 20.

The device works as follows.

When turning on the drive 4 of the drum 1 and the drive 12 of the hollow shaft 13, the drum 1 and the shaft 13 begin to rotate at the same speed, but in different directions. Through the loading devices 5 inside the hollow shaft 13, granules are delivered with chips, which are formed as a result of transportation. Through the window 15, in the hollow shaft 13, the granules and the crumb fall onto the inner surface of the drum I. In the perforated portion of the drum 1, the crumb separates and falls into the tray 9, and the granules are picked up with elastic tape 18 fixed to the blade x 17 and move along the corundum surface grinding rings 8. As a result of contact with the corundum surface of the rings 8, the surface of the granules is ground, and the crust forming through the perforated gaps between the grinding rings 8 enters the tray 9.

The rotation of the helix (belt 18) opposite to the direction of rotation of drum I contributes to the separation of the crumb and grinding of the pellets by moving and contacting the product with the inner surface of the rings 8. In addition, the belt 18 cleans the internal surfaces of the drum 1 and the rings 8 in case of sticking product particles.

The ground granules are moved to the area of the coating, where they are picked up by the deflectors 7, raised to a height of no

its radius of the drum 1 and fall down, being covered with a film-forming composition sprayed by nozzles 16, to which a film-forming composition is fed along the inner surface of the hollow shaft 3.

Gradually, moving under the weight of its own weight and the inclination of the drum 1 to the horizon, the granules through the unloading window 20 get into the special equipment, the first 6 times the discharge of the product. The chip entering tray 9 is covered with a film-forming composition using nozzles 11, creating an upward flow. In order for the tailpiece to be completely covered with film from all sides, a fairing 10 is pivotally mounted in the tray 9, around which the nozzles 11 are installed so that the sprayed film-forming substance is directed tangentially to the surface of the coating coated with anti-adhesive material. With such a relative arrangement of the nozzles and the fairing inside the tray 9, a fine mist of film-forming substance is formed, in which a gentle one soars, gradually lowering itself to the outlet of the tray 9.

The hinged attachment of the flap 0 allows it to move somewhat (vibrations, vibrations) relative to the vertical axis under the influence of directional jets of film-forming substance. Such a setting of the fairing contributes to more efficient spraying and application of the film-forming substance to the surface of the crumb of the granules.

After the shredding passes through the tray 9, small granules are formed, covered with film-forming composition, which, after sorting by size, are used as starter food for fry and juvenile fish.
