Unit for vibro-impact dehydration of wastes of food production in the press-form
It is described the unit with hydropulse drive for a threestep vibroimpact dehydration of wastes of food production (distillery stillage, spent grains, beet pulp, barley coffee and sludge) in the closed mold. Made using the standprototype experimental verification of capabilities of the proposed facility showed that it could provide in comparison with the known machines for the mechanical dehydration of 10-60 % lower final moisture content of waste, compared with equipment for thermal and electrolytic dehydration in 270-920 times less power consumption, as compared with units for the implementation of chemical and biological methods - better performance of workflows. In addition, a comparison of the unit with previously developed by the author complex of multistage dehydration of four separate pieces of equipment, based on calculations, showed a higher efficiency of the first: 9,5 times better performance and 33 times lower power consumption of dehydration, proposed equipment has a lower consumption of materials and dimensions, high reliability and security for staff. The article also provides formulas for determining these indicators of economic efficiency of the vibroimpact systems for dehydration of wastes of food production in the closed mold.
