The spiral conveyor 12 is connected to the humidity control tank 4 via an elevator, and is connected to the drying net 6 of the drying section 2.
a, 6b, 6c, and 6d are recirculating grain dryers whose widths are made smaller as they become closer to the inner side of the drying nets, and which are detachably attached to each other. ,6c,6c
can be easily removed and cleaned, and the rotary valves 10, 10... can also be cleaned.
After cleaning is completed, install the drying nets 6b, 6b, 6a, 6a in the reverse order from the small drying nets 6c, 6c with the smallest width, and finally attach the side plates 13, 13 to the drying section. Because it engages with 2,
It has the characteristic that it is easy to attach a drying net.
