Description

 The invention relates to agricultural production, namely to the processing of animal waste into feed.

 A known unit for the production of meat and bone meal, which contains a grinder, digester for cooking and sterilization of raw materials, a rotary strainer for separating broth and fat from the cooked raw materials, a dryer and a crusher of pulp [1].

 The known unit is inefficient due to the need for long cooking of raw materials, and the resulting meat and bone meal has low nutritional value due to the loss of easily digestible substances with secreted broth and fat. In addition, during the long cooking process, a number of valuable organic compounds are destroyed.

 The known line for the production of dry animal feed K7-FKE, the number of similar features and technical nature closest to the proposed line [2].

 The K7-FKE line includes a grinder for coarse and fine grinding, a dehydrator of raw materials, a dryer and conveyors.

 The disadvantages of the line should also include the low nutritional value of the finished product due to the removal of nutrients from the liquid separated from the raw materials on the dehydrator and also due to the destruction of a number of organic compounds when cooking raw materials in the dehydrator. The well-known line consumes a lot of energy going to the cooking of raw materials, as well as to heat the elevator, feeding the welded raw materials for drying.

 The purpose of the invention is improving the quality of feed and reducing energy consumption.

 The goal is achieved by the fact that the line is equipped with a cutting table with saws installed in front of the grinder for coarse grinding and a feeder of dry feed additives connected to the dehydrator, while the dehydrator is made in the form of a screw mixer, and the fine grinder is located between the coarse grinder and the screw mixer.

 The presence in the line of a cutting table with saws makes it possible to revise the supplied raw materials, which may be fallen animals and birds, slaughter, incubation and fish waste. During the audit, the raw material is divided into uniform pieces, which ensures uniform loading of the grinder for coarse grinding, increases its reliability and quality of grinding. The implementation of the dehydrator in the form of a screw mixer connected to a feeder of dry feed additives helps to prevent the release of liquid with nutrients that are redistributed between the liquid-absorbing dry additives mixed with raw materials. As dry additives, granular compound feeds, grass meal or dry meat and bone meal can be used. This prevents loss of nutrients, improves feed quality and reduces energy consumption.

 The drawing shows a diagram of a line for the production of dry animal feed.

 The line includes a stationary loader 2, a cutting table 3, a scraper conveyor 4, a grinder 5 for coarse grinding of raw materials, a reloading scraper conveyor 6, a grinder 7 for fine grinding, a dehydrator of raw materials in the form of a screw mixer 8 connected to a feeder 9 dry feed additives, and a dryer 10. The latter is made in the form of a two-way countercurrent drying drum 11 with a loading and unloading head, under which a conveyor is installed 12 unloading of finished products, communicated with the storage hopper 13 for collecting meat and bone meal and device 14 for packaging of finished products. The drum 11 is connected to the furnace 15 and connected in series with a scrubber 16, a fan 17 and a pipe 18 for discharging waste heat carrier.

 The line works as follows.

The loader 2 places the carcasses of the fallen animals on the cutting table 3, on which the carcasses are cut and revised. After that, the front side of the table 3 is lifted by a loader 2 and the carcass pieces are dumped onto the scraper conveyor 4, which feeds the raw material to the grinder 5 for coarse grinding of the raw material to a particle size of 20-30 mm. The crushed mass by the transfer conveyor 6 enters the grinder 7 for fine grinding, which can be used as an industrial meat grinder. In the grinder 7, the raw material is crushed to a particle size of 1 mm The resulting meat and bone forcemeat is fed into a screw mixer 8, where dry feed additives are introduced. As a result of the redistribution of fluid between the ingredients, the moisture content of the mixed mass is brought up to 70-75%. This mixture was dried in a dryer 10 in the flow of the drying medium having a temperature of ^about 650-700 C. The drying process lasts 40-45 min. Finished products - disinfected meat and bone meal, enriched with additives, is discharged into the storage hopper 13, and from it into the device 14 for filling.

 The line provides increased productivity and feed quality while reducing energy costs for their production. (56) 1. USSR author's certificate N 281146, cl. A 23 K 1/10, 1969.
