Abstract: Aiming at Programmable Logic Controller (PLC) as main controller of treatment system of animals which suffer from animal-borne disease. The article introduces a kernel process which named treatment of high temperature and high pressure. It describes the system structure, a part of system flow chart. It provides some measures for improving produce safety. Based on fuzzy PID algorithm, the system possesses the advantages of
high control precision, good reliability and high automaticity. So, it performs excellently in the application and satisfies the needs of actual production.
Key words: auto control; PLC; high temperature and pressure; farming garbage processing
