Abstract
Due to the growing need to substitute expensive foreign-made feed products need for expanding food resources in the Russian market appears. The disadvantages of existing technological lines for the preparation of mineral feed additives are high specific energy consumption, low economic efficiency and inadequate conditions for environmental safety insuring. That is why energy-efficient production method for the feed additive based on zeolite and a technological line for its realization was developed at the Department of Technology of bread, pastry, pasta and grain processing industries in VSUET. Application of refrigeration unit operating in heat pump mode allows preparation of heat transfer agents with a maximum utilization of secondary heat sources. After drying the spent drying agent is fed to the preheating methioninate copper suspension through the regenerative heat exchange, then to the dehumidification into the evaporator of refrigeration unit and then it is returned to the first section of the two-part condenser in closed-loop mode. Feed fat is heated to 55 ... 60 ° C, by "hot water", heating of which takes place in the second section of the 11th condenser to the temperature of 70 ... 75 ° C and is fed into the jacket of fat melting device. Then it is returned to the second capacitor section to form a recirculation loop. We developed a feed additive with the following particle size distribution: a large fraction of 2.8%, the average fraction of 95.2%, the fine fraction of 2.0%, the residue on the sieve with a mesh № 1,2 of 2,0%, with a moisture content of 6.2%, the angle of repose of 42 deg., dispersibility of 6.9%, a bulk density of 385 kg / m3. The proposed method for the production of the feed additive based on zeolite ensures environmental safety of production due to closed recirculation circuits on material and energy flows, helps to reduce energy and resource consumption for the production of the feed additive, to obtain high quality product with high uniformity and low moisture content.
