METHOD OF PRODUCING SEMOLINA BY WET GRANULATION TECHNOLOGY USING PHOTOTROPHIC BIOMASS AND FUSA OF ORGANIC OILS AND PRODUCTION LINE TO THIS END

摘要

FIELD: process engineering.;SUBSTANCE: proposed invention may be used in production of semolina from animal feed by wet granulation technology. Proposed method comprises granulation of loose animal feed with addition of liquid component into press granulator, drying and cooling of granulated animal feed, crushing of obtained product and its fractionating into three fractions: large, medium and fine fractions. It includes also feeding large fraction for crusging and discharge of medium fraction as finished product. Said liquid component represents phototrophic biomass of micro seaweed added to animal feed in mixing in amount of 10…15%. Granulated animal feed is air dried at 70…80°C and with air flow rate of 2300…2700 m³/(h·t), and cooled by air at 7…10°C and with air low rate of 1200…1400 m³/(h·t). Medium fraction, prior to discharging it in the form of finished product, is dragged by vegetable oil fusa in amount of 10…12 wt % of medium fraction weight. Vegetable oil fusa is preheated to 60…70°C, enriched by anti-oxidising agents and fat-soluble ferments and filtered. Then obtained product is coated by fine fraction. Finished semolina is kept in ventilated hopper. Absorption refrigerator is used for recovery of cooling and hot air, as well as for heating water used for heating vegetable oil fusa. Proposed production line comprises animal feed hopper, press granulator, cooling column divided into drying and cooling zones, toll mill and two-sieve screening machine. Additionally, production line comprises site for seaweed growing, dragging site, vegetable oil fusa preparation site, finished semolina storage and absorption refrigerator.;EFFECT: expanded range of animal feed, increased biological value.;2 cl, 1 dwg
