Abstract Aiming at the problems of wolfberry quality and yield affected by wet weather in mature season, dual temperature
control system with solar and thermal steam are proposed which is based on S7-200 series PLC. Using experimental methods,
the system realized temperature control to wolfberry drying kiln model with better effect in the testing machine, and it can
achieve the purpose of improve product quality and energy saving
Key words wolfberry 57-200 PIC energy saving
