Design of Intelligent Circulation Ventilation Granary Based on PLC
In order to accelerate the intelligence and information of food storage,the loss of food in the storage process is minimized.Aiming at the problem of uneven ventilation of grain storage,a new type of circulating in-telligent grain storage bin and its control system are designed in this paper.The system mainly consists of two parts:circulation air duct and bottom longitudinal air duct.Through the PLC control sensor to detect the temper-ature and humidity in the warehouse,the fan start and stop,the valve switch and other functions,the circulation ventilation and longitudinal ventilation of the grain storage bin are controlled according to the grain situation,so as to ensure the equilibrium of grain temperature,reduce the grain dew,inhibit insects and mildew,etc.The re-search and development of this system provides a new method for the ventilation operation of grain storage.It provides a theoretical basis for grain storage and food security.
