Rationale for the design and technological parameters of the extruder for the production of sapropel and grain feed

It is reasonable to use extruded sapropelesern feed for increasing the productivity of farm animals. This feed supplements the animal’s body with minerals and vitamins as well as has good digestibility. It is well stored and has a low cost. The article shows the scheme of the extruder developed by the authors. It allows to prepare sapropel and grain feed. For the aim of being able to specify the necessary technological parameters of the extruder operation at the design stage, analytical dependences were deduced to determine the processing temperature of the mixture, extruder capacity and the power spent on the extrusion process. The mathematical dependences received theoretically were tested experimentally, and the maximum error does not outweigh 5%, corresponding to the required accuracy of the modelling. The article also determines the most rational modes of extruder operation.
