Abstract

Humic drugs have a wide range of biological activity, affecting the metabolic processes in the body of animals and humans. Humins play a vital role in protecting the intestine from infections and favorably affect its functions, have the potential to suppress mold and bacterial growth, and reduce the level of toxins. When goats received humic substances they had higher milk yields, while significantly reducing total blood cholesterol. Sodium humate administered to broiler chickens increases the live weight by an average of 5–7 % and the livability of poultry by 3–5 %. The influence of humic acid on the quality of laying and egg quality in Japanese quails has been studied. The implementation of socio-economic and environmental programs of the agro-industrial complex provides for the improvement of technologies and technical means for the production of compound feed and protein-mineral vitamin additives for farm animals and poultry. The purpose of the research was to select a vacuum evaporation plant to increase the concentration of humic gel. It has been found that to increase the concentration of humic gel, it is advisable to use a vacuum evaporation plant with an ejector and a steam condenser. Methods for calculating the parameters of the ejector and the pressure reduction process in a vacuum evaporation unit have been developed. The dependences obtained to study the correlation between the area and the diameter of the nozzle water-air ejector, mass flow inject air, water pressure before the working nozzle, pressure inject air, density of the working water, pressure after the ejector, pressure of saturated steam, working temperature of water, temperature inject air, pressure reduction time.
