Abstract


In this work, a control strategy for grain aeration system was proposed. Aeration is the process of forced movement of ambient temperature controlled air through a grain bulk, which will help to preserve or improve the physical conditions of the stored grain. This strategy was implemented using a microcontroller by relating a relative physical condition like temperature and humidity. The objectives of grain aeration are to maintain the temperatures inside the storage area, whenever the conditions inside the chamber deviate from the predefined value, to prevent the storage grain from contamination. This method was supposed to preserve grain over a long time without use of chemical agents or harmful substance. It has been receiving more attention among the local population as the small scale farmers where more benefited as it is cost efficient and also requires less maintenance compared to that of costly coolant chamber method. The results showed that the proposed strategy is efficient to achieve these objectives.
