Description

CO 4 00 Od 00 The invention devotes itself to the field of fodder production, in particular, the processing of granulated products from powdered mixtures and can be used in the production of granulated feed, mainly for fish farming. The purpose of the invention is to increase the uniformity of the granules. The method is carried out as follows. Example 1. A feed mixture powder prepared according to compound feed 111 No. 10 ukr 15 for growing carp in cages on warm waters, taken in an amount of 2 kg, when moving in a laboratory mixer type LM, 100 ml of 25% is sprayed over 1 hole an aqueous solution of sulphate-yeast brew. At the same time, the powder mixture is treated with live steam in the amount of 3% by weight of the powder mixture being granulated. After that, the mixture is placed in a vibrating granulator and granulated for 6 minutes at a vibration frequency of 50 Hz and a vibration amplitude of 1.5 mm when purged with air and spraying a 200% 25% aqueous sulphate yeast solution for the first 2 minutes. The system analysis of the forming granulate is shown in Table 1. Table 1

Example2. To feed the powder mixture prepared according to the formula 111 1 10 Ukr 154 to entrap carp in cages on warm waters, taken in an amount of 2 kg, sulfite-containing 25% aqueous solution was sprayed with a LMT type laboratory mixer through a nozzle: yeast brew. At the same time, the powder mixture is treated with direct steam in an amount of 4% by weight of granu80 4.0 Prototype
