USING A SINGLE-BOARD RASPBERRY PI COMPUTER TO CONTROL THE TEMPERATURE OF MILK FERMENTATION IN CHEESE PRODUCTION

Abstract

A study of the food industry has been carried out. A number of problems have been identified that are associated with the low technical level of enterprises and the use of manual labour, which affects the quality and efficiency of production. Particular attention is paid to the area of milk fermentation in cheese production, and the instability of the control system is identified. The methodology of automatic control theory with correction of system parameters was applied, which allowed to achieve system stability. To improve the quality indicators of the system, the use of a single chamber was considered, the necessary technical means of automation were selected, and an electrical circuit for temperature control during fermentation with a PID controller was developed. The transient characteristics are obtained and the system control time is determined.
