ON THE ISSUE OF PRELIMINARY DEHYDRATION OF CHICKEN MANURE DURING ITS EXTRUSION PROCESSING

Abstract

The technological validity and economic feasibility of processing chicken manure into organic fertilizer are determined by its quantity and humidity. The currently known technologies for processing chicken manure are applicable only to its litter variety, since they allow reducing the humidity of the processed raw materials by no more than half of the initial one in one processing cycle. An additional technological operation associated with the preliminary dewatering of this raw material is a prerequisite for the effective processing of bespodstyle manure by extrusion processing. The paper analyzes the technical means for performing this operation and proposes a design and technological scheme of the unit, which allows to regulate the intensity of pre-dehydration of raw materials processed into fertilizer.
