STUDY OF THE ENERGY SUPPLY SYSTEM OF THE DIGESTER WITH SMOOTH POWER REGULATION
It has been established on the basis of the results of information and patent research that there is a wide range of cooking gas-using boilers with a different level of automation of the process of thermal processing of the product and ensuring safety during operation. An analysis of power supply systems in digesters and heating boilers showed the feasibility of developing a new advanced power selfregulation scheme based on semiconductor thermoelements. The allowable voltage parameters of a thermoelectric battery for calculating the number of thermoelectric elements necessary for the operation of an existing experimental sample of a gas-using power supply system of a digester with self-regulation of power were determined, the minimum voltage is 0.7 V; maximum voltage 7 V. Research was carried out on the development of an energy-saving gas-using digester with gas flow control in proportion to the heat flux consumed in the process of preparing feed or food. Experimental studies have shown that the use of an energy supply system with gas burner power control in proportion to the consumed heat flow of the digester allows energy savings of up to 19.75%. At present, a promising system has been created for automatic control of gas flow according to the temperature difference that changes during heating - the temperature difference between the steam and the surface of the brewing vessel. Semiconductor elements are adopted as the main gas control unit, which control the gas valve actuator without an intermediate amplifier. Experimental studies have confirmed the promise of using digesters with proportional control of gas flow
