Humic preparations belong to natural growth regulators. Humic preparations eliminate the negative effects of factors unfavorable for the development of plants, normalize the processes of intracellular metabolism. Humic substances are adsorbed on the cell wall of the animal organism, increasing the elasticity of its membrane and increasing the surface of the cell, this leads to an increase in the amount of oxygen and metabolism entering it. With the introduction of humic substances in the diet of cattle, the average daily increase in live weight increases by 14.4%. When used as an additive in chickens feed, the average daily increase increases by 11.85%, the weight of the heart, liver, spleen, and gall bladder up to 20.7%. The average daily gain in sucking piglets is increased by 8.3%. A line with a vacuum evaporator was developed to increase the concentration of humic suspension. The installation consists of a heating chamber, a steam pipeline, a steam condenser, a condensate tank, a water-air ejector, a cooler, a water tank, a centrifugal pump, a hot water supply pipe to the heating jacket, a water drain pipe from the shirt, a working water pipe, a pressure gauge, vacuum gauges, a thermometer.
In agriculture, the use of humic preparations can increase the productivity, productivity of animals and poultry. The growth rate of consumption of humic preparations in 2021 … 2025 will be from 1 to 5% per year and the market capacity in Russia will be 1500 tons per reptile. Improvement of equipment for the production of humic preparations is urgent. The physical and mechanical properties of the humic suspension have been determined. In the production of humic preparations, medical centrifuges OS-6MC, a flow-through sedimentation centrifuge and a periodic vacuum evaporator (VVU) were used to increase the concentration of humic suspension. In terms of the energy of germination and germination of spring wheat, a rational method for increasing the concentration of humic suspension by evaporation has been substantiated. We have developed and patented a line with VVU to increase the concentration of humic suspension [21]. At the exhibition Golden Autumn - 2020 (Moscow) “For the production of highly efficient agricultural machinery and the introduction of advanced resource-saving technologies”: Kurgan State Agricultural Academy was awarded a bronze medal and a diploma: “For the development of a line for the production of a humic preparation.” When the time for the VVU to enter the operating mode is the sum of the heating time of the installation to the operating temperature and the time for the pressure drop in the installation from atmospheric to working. A method has been developed for calculating the time the vacuum evaporator reaches the operating mode at start-up. The heating time of the VVU with a tank of 50 liters from the initial installation temperature of 10 ° C to the boiler temperature of 85 ° C, and of the humic suspension to 60 ° C will be 30 minutes at a power source of 12 kW, which is confirmed by experiment. A method for calculating the parameters of the process of lowering the pressure in the VVU has been developed. Dependencies are obtained for studying the relationship between the design and technological parameters of the VVU when the pressure is reduced from atmospheric to working. The time of pressure reduction with a volume of 1 m3 of the vacuum system will be 5 … 6 minutes, which is confirmed by experiment.
