Description
Summary:Further development of the human community depends on two main tasks to be performed, i.e. providing the population with high-grade food and preserving the environment due to the rational use of natural raw materials. In this regard, processing of secondary milk raw materials is considered a controlled impact on a complex biotechnological system. The impact was divided into preliminary treatment and final processing and is based on two principles; firstly, secondary dairy raw materials must be standardized before the initial stage of its deep processing, involving fractionation; and secondly, the first step of the baromembrane purification of secondary milk raw materials should ensure the purification of the permeate from proteins and milk fat. The purpose of the study was to theoretically substantiate and experimentally determine the optimal operating parameters of the baromembrane processes in the technology for obtaining highly purified whey permeate. The authors have experimentally established that the deep baromembrane purification of milk whey ensures the optimal values of the working pressure and circulation rate of the separated system that are P= 0.45-0.5 MPa and V=0.15-0.2 m/sec in the channel of the ultrafiltration apparatus and P=1.5-2.5 MPa and V=0.16-0.26 m/sec in the channel of the nanofiltration apparatus, respectively.
