The Design for Fluctuating Pressure Curing Equipment Automatic Control System based on Single Chip Microcomputer

As a traditional food processing technology, pickling technology needs to be inherited in today’s society, but it also needs reform and innovation. So how to process food faster and better and save time and manpower to the greatest extent becomes an urgent problem to be solved. In this paper, the NKY-01 pulsating pressure pickling equipment is developed. The equipment adopts an automatic control system with PIC16F185 microcontroller as the control core, and monitors the pickling equipment through PIC16F1825 microcontroller and pressure sensors. In this way, the control of process parameters such as pressure, pulsation period, and atmospheric pressure ratio is realized. By combining automatic control and pulsating pressure, the system saves a lot of manpower, greatly improves work efficiency, and is easy to operate and control under the premise of ensuring food taste and quality. It can be widely used in food processing production lines.
