| Abstract: | Humidity of air and dehydrate rate of material were monitored in the drying process by humidity and gravity senses.Data of temperature,humidity and dehydrate rate were collected exactly and real-time.The process of drying was monitored by PLC based on drying character of agricultural material.The experimental results showed that the system could monitor and control drying process of agricultural material efficiently and improve drying quality significantly. |
