Influence of technological modes on changes in the composition of beet pulp during its processing at the Borinsky sugar plant

The description of the technological scheme of the granulation site at the Borinsky sugar plant is given, with an analysis of the work of the main types of technological equipment to identify problem areas of production. It is established that the use of such a promising press as the one of the Babbinni company allows you to get pulp with a humidity of 68-76 %. To dry it in a drum dryer to a humidity of 11-13%, 170 m3 of natural gas is consumed per 1 ton of pulp. The technological process of obtaining granulated beet pulp includes pressing the initial beet pulp with an initial humidity of 85-90% to a humidity of 68-76 %; drying the pressed pulp with a heat carrier at a temperature of 110-140 °C for 90-120 minutes to a final humidity of 11-13 %; cleaning pellets from metal-magnetic impurities; granulating the pulp (the diameter of the pellets is 10 mm); cooling pellets to a temperature of 30-35 °C; fractionation of pellets into large and small fractions; weighing and shipping granulated beet pulp to the warehouse of finished products. The technological modes influence analysis of beet pulp pressing, drying and granulating processes at the Borinsky sugar plant showed the need to introduce a second stage of pressing to further reduce the moisture content in the pressed pulp. Obtaining pressed pulp with a lower moisture content will significantly reduce the energy consumption for moisture evaporation in the drum dryer. Reducing the duration of the heat drying process of pressed beet pulp in a drum dryer will significantly increase the nutritional value of the granulated beet pulp produced.
