1.We need to measure the initial moisture of grain that before drying, then put the grains with similar initial moisture together as a group, then we will adopt reasonable drying methods in line with the initial moisture of each batch.
2. According to the standard operating procedures, we need to setup the upper and lower limits of standard-setting instrument control.
3.Timely close the value of induced draft fan, then open induced draft fan. Then we can slowly open the valve until the fan has returned to normal.
4. After guaranteeing the smoothly running of fans of grain dryer, we will start the pre-cleaning cylindrical screen and bucket elevator, when the values of bucket elevator’s feed hopper are open to the appropriate location,we will start to put wet grains into pre-cleaning cylindrical screen, when there is food in the back to grain tube, we can stop feeding grains.
