Abstract

Abstract:

Industrial production of edible fungi is the future development direction of China’s edible fungi industry. At present， the industrial production of edible fungi in China is dominated by wood-rotting fungi， and its production process includes bottling， sterilization and a series of links until the end of bottle digging. However， after bottle digging， the bottle cleaning still adopts manual cleaning， which leads to low washing efficiency and high labor costs. Based on analyzing the requirements of bottle washing in the industrial production of edible fungi， this paper introduces the working principle of bottle washing machines in the industrial production of edible fungi and designs the control system of bottle washing machines on this basis. Around the hardware and software system， this paper analyzes the functions and main model selection of the drive module， actuator module， sensor module， and designs the pneumatic drive system. According to the process of the bottle washing machine， using Guangyang SH-32R as a programmer， the electrical schematic diagram is drawn， and the control program of the bottle washing machine is written in level language. The trial production and test show that the bottle washing machine runs smoothly， the average pressure of the nozzle is 0.33 MPa， the water consumption of each bottle is 0.1 kg， and the single cleaning time is 10 s， which meets the requirements of industrial bottle washing.

Key words: edible fungi, factorization, control system, bottle washing machine, PLC
