The grains harvested in the field are appropriately supplied to the starting end of the pitching conveyor 51 and pitched into the tempering section 1 of one of the grain drying units ff1B. When the prescribed grain pitching is completed, the drying switch (not shown) is turned on. ONL, then move on to the drying process. #2 material is dried with hot air while flowing down through the ventilation drying section 3. The dried grains are lifted up by an elevator 15 and then returned to the tempering section 1 where they are tempered.

The drying process is repeated until a predetermined moisture level is reached, and the drying process is completed, but when discharging the drying material, it is possible to choose between discharging into a cooling tank or discharging onto a conveyor.
Normally, the grain is transferred to a cooling tank 5 in order to lower the grain temperature. In this case, the position of the switching valve 17 is switched from the first opening supply side to the second opening supply side.

During cooling, the feeding portion 27 transfer spiral 30, 30 is stopped, and when a predetermined cooling time has elapsed, the drive motor 46.46 is started. The grains in the cooling section 25 are fed out to one side by a transfer spiral 30°30 while flowing down inside the inner frame 29, which has an inclined surface formed on the front, right, left, and four corners toward the center, and is extended to one side @137. 37, and is dropped onto the discharge conveyor 50 surface via the downstream guide tubes 47 and 47 and discharged.

In the above work process, the bottom valves 31, 31 are maintained in the closed position, but when the amount of grain to be processed is large, the cooling tank 5 is used as a storage tank during receiving, and when the processing in the drying section 4 is completed, , the grains in the cooling tank 5 are transferred to the drying section 4
In this case, the bottom valves 31, 31 and the drive motors 33, 33 are rotated in the normal direction to open the feeding section 27, and the high moisture grains in the cooling section 25 are removed. The water is allowed to flow F into the thermal refining section 1 on the left side, and the process proceeds to a predetermined drying process.

The grain transferred by the discharge conveyor 5o is supplied into the storage hopper C by an attached elevator, and after waiting for the completion of the subsequent hulling process, it is supplied from the hopper C to the hulling device ff1D, and then to the finishing tank E. After being stored, it will be weighed using a weighing device ff1F, or it will be packed into lightweight bags using a small vertical sorting and weighing device G.

On the side of the extension connecting trough 37, the transfer helix 30 can be withdrawn together with the extension connecting trough 37 by removing the opposite bearing member 34.35;
．． 35 side, the extension connection gutter 37 and the bearing member 52 at its inner end. By removing the transmission pulley 53, it can be pulled out and removed from either the front or rear of the machine frame, making maintenance and inspection easy.

The cooling tank 5 has finished drying! In addition to storing the grain and lowering the grain temperature, it also functions as a tempering tank when there is a large amount of grain to be dried, as mentioned above. Preliminary drying can be carried out by horizontally installing intake frames 54, 54, . It's convenient. At this time, suction and
Providing a higher proportion of exhaust frames on the lower side is advantageous in that the removal of moisture that tends to accumulate in the lower part is facilitated, and in particular, it is possible to reduce stagnation of grain flow at the inclined guide wall portion of the feeding section 27.

The figure shows a case in which harvested grains are stored in a so-called flexible container bag 57, transported, and used for a work configuration in which they are introduced from pit A. In order to maintain the bag shape of this flexible container bag 57, a porous pipe material is formed inside the flexible container bag 57. By inserting the stand 58 that has been removed, the work effort is reduced.

Furthermore, a fan (not shown) capable of supplying compressed air may be connected to an appropriate position of the stand 58 to prevent the internal grain from suffocating.
