Description

The invention relates to the feed industry and can be used in the production lines of extruded feed.

The closest in technical essence and the achieved effect is the extruded compound feed production line, including a grain cleaning separator, a magnetic column, a hammer mill, a batcher, a mixer, a humidification unit, an extruder, a cooler, oil shaker [Chernyaev N.P. Combined feed production [Text]. - M .: Agropromizdat, 1989 .-- 224 p. S.179-180].

A disadvantage of the known line is the restriction of the processed product by the amount of fat, as well as a narrow range of products.

An object of the invention is to increase the technological capabilities of the line for the production of animal feed of a given nutritional value, as well as expanding the range of manufactured animal feed of high quality, i.e. obtaining a finished product enriched with fats and vitamins, adapted for various types of animals and fish.

The task is achieved in that in the production line of full-extruded extruded compound feeds, the new one is that it contains a hopper for starch-containing components having rotary batchers, a hopper for storing fat-containing components and a hopper for storing a mixture of protein-vitamin supplements and chalk, and the hopper for storage of starch-containing components communicated by means of a dispenser with a working chamber of the extruder, a hopper for storing fat-containing components communicated by means of a dispenser with ext with an additional oil separating nozzle connected to a container for stabilizing the fat mixture, both extruders are connected in series with a cake press and a granulator, the granulator is in communication with a device for applying stabilized vegetable oil, and the device for applying a stabilized vegetable oil is connected with a container for stabilization of the fat mixture and pelleting apparatus, pelleting apparatus communicated through a dispenser with a hopper for storing a mixture of protein-vitamin Doba ok and chalk, with a filling and packaging machine and oilseed squeezer, in addition, rotary dispensers are installed in the lower part of the hoppers, the tank for stabilizing the fat mixture is equipped with a rotating closed turbine mixer having the shape of a wheel with curved blades mounted on a vertical shaft, an apparatus for applying stabilized vegetable oil is a case inside which there is a conveyor belt, over which nozzles are installed for spraying vegetable oil over a layer of extruded granules ul located on the upper conveyor belt, and the coating drum is made inclined, placed in the housing and its unloading part is perforated to separate the product into fractions.

The drawing shows a General view of the production line of full extruded extruded animal feed.

The production line of full-extruded extruded compound feeds (drawing) contains silos for starch-containing components 1 (wheat, triticale, rye, etc.), silos for storing fat-containing components 2 (soy, rape, sorghum, etc.), storage silos mixtures of protein-vitamin supplements, premixes and chalk 3 with rotary dispensers installed in their lower part, extruder 4 with additional oil separating nozzle 13, extruder 5, cake press 6, press granulator 7, container for stabilizing the fat mixture 8, apparatus for applying st vegetable oil 9 with nozzles 10, panning drum 11 for applying a mixture of protein and vitamin supplements, premixes and chalk, filling and packaging machine 12. The tank for stabilizing the fat mixture 8 is equipped with a rotating closed turbine mixer 14, which has the shape of a wheel with curved blades, mounted on a vertical shaft 15. In this case, mainly radial fluid flows are created in the container 8. Along with the radial flow, a tangential (circular) flow of the mixture of vegetable oil and stabilizer and the formation of a funnel arise. In this case, reflective partitions are installed in the container 8. This ensures intensive mixing in the entire volume of the tank 8. The power consumed by a turbine mixer operating in a tank with reflective baffles, with a turbulent mixing mode, is practically independent of the viscosity of the medium. Therefore, agitators of this type can be used for mixtures whose viscosity changes during mixing. Closed turbine mixers create a more pronounced radial flow.

The apparatus for applying stabilized vegetable oil 9 is a housing inside which a belt conveyor 16 is placed. Above the belt conveyor 16 nozzles 10 are installed for spraying the stabilized vegetable oil coming from the tank 8 over a layer of extruded granules located on the upper conveyor belt.

The panning drum 11 for applying a mixture of protein-vitamin supplements, premixes and chalk is an inclined rotating drum located in the housing. The unloading part of the drum 11 is perforated for draining and subsequent removal of the small (passage) part of the granules into the confuser, as well as an excess of a mixture of protein-vitamin supplements and vegetable stabilized oil. Extruded granules with oil and a mixture of protein-vitamin supplements, premixes and chalk are also fed into the feed hopper 17 of drum 11.

The proposed line for the production of full extruded extruded feed works as follows (drawing).

The initial starch-containing components (various grain raw materials of a given fractional composition with an initial moisture content of 12 ... 14%) stored in the hopper 1 are supplied by the dispenser and through the loading nozzle enter the working chamber of the extruder 5. The drive is turned on and the rotating screw of the extruder 5 begins to capture and move a product that sequentially passes through the loading, mixing, homogenizing and dosing zones.

At the same time, the initial fat-containing components (various grain raw materials of a given fractional composition with an initial moisture content of 12 ... 14%) stored in the hopper 2 are supplied by the dispenser to the working chamber of the extruder 4. The drive is turned on and the rotating screw of the extruder 4 starts to capture and move the product into the matrix zone , where the oil separating nozzle is installed 13. The pressed vegetable oil enters the tank 8 to stabilize the fat mixture, where it is mixed with stabilizers supplied to it (fumaric, ascorbic acid, etc.).

The need to squeeze out the fat-containing components from various grain raw materials (soy, rapeseed, sorghum, etc.) and their subsequent application to the surface of the extruded granules is due to the fact that for the normal extrusion process the content of fat-containing components in the initial grain raw materials should not exceed 6% [ Ostrikov, A. N. Extrusion in food technology [Text]. / A.N. Ostrikov O.V. Abramov, A.S. Rudometkin. - St. Petersburg :. GIORD - 2004. - 288 p.]. Otherwise, the dissipation effect decreases sharply, i.e. conversion of mechanical energy into thermal energy due to friction forces, and grain raw materials are not subject to swelling.

Vegetable oil and stabilizers enter the tank 8 parallel to the axis of the shaft, the resulting mixture is discarded by the stirrer in the radial direction and is subjected to intensive mixing with emulsifying (grinding fat balls) effect.

The extruded starch-containing components from the extruder 5 and the cake from the extruder 4 are sent for grinding to the oil cake 6 and then to the press granulator 7, in which granules are formed from the mixture of components.

Then the granules are fed into the apparatus for applying stabilized vegetable oil 9, in which, moving along the surface of the conveyor, the granules are processed with stabilized fats coming from the tank 8 to stabilize the fat mixture through the nozzles 10.

Next, the processed granules are fed into a coating machine 11, which also receives a mixture of protein-vitamin additives, premixes and chalk from the hopper 3. Due to the good adhesion (surface adhesion forces), the mixture of protein-vitamin additives, premixes and chalk is evenly applied to the surface granules. Due to the fact that the unloading part of the coating drum 11 is perforated, it separates the product into fractions. The off-cut fraction is sent to the filling machine 12. The pass-through fraction (fine fractions) is sieved through a sieve and enters the confuser to collect fine fractions. Then it is sent to the oil cake 6 for their subsequent processing.

Thus, the use of the invention will allow:

- expand the range of multi-component feeds of a given nutritional value, adapted for various types of animals and fish;

- to increase the nutritional value of multicomponent feed by targeted regulation through the use of raw materials of various compositions.
