In order to solve the problems of insufficient resource utilization of kitchen waste, high pollution of waste treatment and high energy consumption and inconvenient operation of waste treatment equipment, an intelligent kitchen waste treatment equipment control system was designed to improve the automation level of kitchen waste treatment. The system was mainly composed of STM32 main control system, motor drive system, weight control system, temperature control system, auxiliary control system, purification system and storage system. The interface of intelligent serial port screen was designed based on USART HMI software. The intelligent serial port screen communicated with STM32 through TTL serial port, which could complete the working parameters setting of kitchen waste treatment and displayed the operation status information of the control system to realize the accurate control of kitchen waste treatment equipment. The experimental hardware platform was built, the temperature range of the system and the ratio of kitchen waste and high temperature aerobic microbial strains were used as experimental factors. The weight-loss ratio and power consumption of kitchen waste were used as experimental indexes. The experimental results showed that the temperature range of the system and the ratio of kitchen waste and high temperature aerobic microbial strains had very significant effect on kitchen waste treatment; when the temperature range of the control system was 85~95℃, the ratio of kitchen waste and high temperature aerobic microbial strains was 15∶1, 30kg kitchen waste and 2kg bacteria were treated for 5h, the weight-loss ratio was 90.38%, the average power consumption was 1.96kW·h, and the treatment effect of kitchen waste was remarkable. The system realized the harmless treatment of kitchen waste. The organic matter after kitchen waste treatment was converted into humus by aerobic composting technology, which was used for field fertilization or animal feed production to improve the utilization rate of waste resources.
