The disadvantages of processing certain types of waste are multi-operation, the complexity of creating waste-free production. A known method of complex processing of brewing waste: beer pellets, malt sprouts, alloy, grain waste, spent brewer's yeast, using heat treatment in a vacuum boiler for an hour at a temperature of 100 ° C, followed by drying in the same boiler to a moisture content of 8-10 % Patent RU No. 2086114, cl. C1.

The disadvantage of this method is the long duration of the process of high-temperature waste treatment, which can lead to protein denaturation. In addition, the named method does not reduce the high level of fiber, the product is released in milled form.

The purpose of the invention is the integrated processing of waste generated during the production of malt and beer with a high content of protein and vitamins and a low fiber content, obtaining the product in granular form.

This goal is achieved by the fact that the pellet is pre-mixed with protein sludge, subjected to dehydration to a moisture content of not less than 65%, followed by mixing with the alloy and drying at a temperature of no higher than 70 ° C to a moisture content of 10-13%. The dried pellet and alloy are subjected to grinding, malt sprouts and grain waste are also milled. Ground solid waste is mixed with liquid waste: residual yeast, camp sediment and, if necessary, with a suspension from dehydration of the pellet and protein sludge until a doughy mass is obtained with a moisture content of up to 55%, which is granulated and dried at a temperature not exceeding 70 ° C. The ratio between different types of waste corresponds to their normative formation in the production of malt and beer at the enterprise.

Example. All the main waste generated during the production of malt and beer: grain waste, sprouts, alloy, residual brewer's yeast, lager sediment, protein sludge, pellet, in the ratio according to the norms of their formation (Table 1) was subjected to complex processing. The average chemical composition of the processed waste is given in table 1.

Protein sludge was mixed with grains. The resulting mass was dehydrated to a moisture content of not more than 65% and mixed with an alloy of 30% humidity. The resulting mixture was dried at a temperature not exceeding 70 ° C to avoid protein denaturation. The dried mixture with a moisture content of 10-13% was mixed with grain waste and sprouts, ground and sieved on a sieve with a mesh size of not more than 0.5 mm. Oversize product was sent for re-grinding. The sublattice product was mixed with liquid residual yeast, camp sediments and part of the suspension from dehydration of the pellet to obtain a pasty mass with a moisture content of not more than 55%, granulated and dried at a temperature not exceeding 70 ° C. The obtained granular product with a moisture content of 8-10% had a protein content of 36.08% in a.s.w., which is 1.43-1.68 times higher compared to the prototype (table 2). The content of crude fiber in our product is 2.14-2.56 times less compared to the prototype, which allows it to be used for the preparation of feed for both livestock and poultry. A comparison of the contents of the remaining ingredients is given in Table 2. The analysis of the obtained feed product was carried out by the Perm State Agrochemical Service Center. The composition of vitamins in the resulting feed product mg / kg CB is given in table 3.
