Abstract

The performance of a fermenter of any design is determined by the totality of hydrodynamic, mass transfer, thermal, technological, and microbiological conditions. The latter two conditions refer to the quality of the initial raw materials, adherence to optimal parameters for conducting the technological process regarding the concentration of nutrient salts, microelements, the amount of spent mash returned to the fermenter, the state of the yeast culture, and so on.

Depending on the technological and microbiological factors, with identical hydrodynamic, mass transfer, and thermal conditions, the apparatus’s performance can fluctuate by more than twofold. Since technological and microbiological conditions are independent of the fermenter design, designers are primarily responsible for achieving the specified conditions regarding the intensity of mixing, mass transfer, and heat transfer within the apparatus. These intensities are determined by the correctness of the design calculations for the main structural elements and the operating modes of the fermenter. The modernization of these devices is the main direction both in improving the primary fermentation equipment for PVC production and in creating new highly efficient apparatus designs. Comparing normalized characteristics made it possible to identify promising technical avenues in the creation of fermenters for feed protein production. The correct choice of fermenter design and its performance largely determines the economic efficiency of any microbiological production.

The goal of the research is to increase the yield of PVC biomass through the development of scientific and methodological foundations for improving the technology and equipment used in the production of protein-vitamin concentrate. This article presents data on the development of a protein-vitamin concentrate intended to replenish the deficit of feed protein
