MODERNIZATION OF THE EXPERIMENTAL TECHNOLOGICAL LINE FOR THE PRODUCTION OF ENZYME HYDROLYSATES OF DOWN AND FEATHER RAW MATERIAL

Abstract

At this stage of the work, a pilot line was prepared for the enzymatic splitting of down and feather primary products including a pre-treatment system for removing impurity inclusions from down and feather raw material, a press for pressing the feather, a transporter of down and feather raw material, a preliminary sterilization unit for down and feather raw material, and an experimental fermentative reactor. In order to optimize the process, the main parameters of the enzymatic splitting of down and feather raw material are selected in the pilot line: irrigation module-8; duration of fermentation-2 hours; the dose of protease enzymatic agent No. 6230/2256-15 unit/g of raw material; the dose of Protolad B enzymatic agent-30 unit/g of raw material. The testing of various variants of the equipment arrangement in the technological line was carried out, as a result of which three preproduction lots of enzymatic hydrolysates with a protein content of 87.5% to 97.6% were obtained. It is determined that all three tested equipment layouts in the pilot line lead to the production of enzymatic hydrolysates from down and feather raw material that meet the requirements of the current regulatory documentation according to physical, chemical, microbiological and safety indicators.
