FIELD: agriculture.SUBSTANCE: invention relates to fodder production, in particular, to processing of secondary products of brewing for production of fodder. Method provides for mechanical dehydration of brewing waste with separation of it into dehydrated waste and suspension received after dehydration of the waste, use of dehydrated grains suspension and residual beer yeast. Mechanical dehydration of brewing waste is performed till moisture content of not more than 60% by way of filtration with formation of sediment and by mechanical pressing of the sediment in the thin layer formed in the gap between two moving endless belts made of filtering material. During dehydration of waste by filtering, a finely dispersed suspension is obtained, which is mixed with residual beer yeast preliminarily subjected to conditioning for inactivation. Obtained mixed suspension undergoes centrifugation and centrate and paste-like fluid sediment are extricated from the mixed suspension. Before drying, the sediment is mixed with dehydrated waste and grain alloy, ensuring achievement of the mixture humidity of not more than 70 %. This mixture is used to create a vibrofluidized bed; drying is carried out at a temperature of not more than 80 °C using the convective technique with blowing of the heat carrier through the vibrofluidized bed. Obtained mixture of dry fodder products is additionally mixed with malt sprouts, aspiration, polishing and grain wastes and is granulated to produce a feed material.EFFECT: invention usage allows to produce highly nutritious protein fodder product.1 cl, 1 ex |
