Ekstruduotųjų kombinuotųjų pašarų džiovinimo proceso tyrimai

Abstract

Steam and water, imposed during the extrusion process in combined fodder, must be evaporated. A dual-stage conveyor dryer is used for this purpose. It requires less space than a single-stage conveyor dryer, but the height is 0.3 - 0.6 meters bigger. The capital cost of multi-stage conveyor dryers is lower than of single-stage conveyor dryers. Following the studies in moisture changes of combined fodder production in different technological stages, was found out that the moisture of the product after extrusion process is 24%, whereas in realization stage the moisture is reduced to 10%, which corresponds to the standard. To obtain a combined fodder grains: wheat, corn, soybeans and others are mixed and crushed. Also, meat bone meal, salt, fat, and no doubt vitamin mineral substances are added, and then sent to extrusion system and then into the dryer to get the final product, giving it the required shape, size and moisture. The article examines moisture changes of combined fodder in the various stages of production. It was found that moisture of combined fodder after the drying process varied from 25% to 10%.
