Abstract

PURPOSE:To prevent grains from becoming stuffy when temperature is high or absorbing moisture when temperature is low by a method wherein the operation and stopping of the ventilation of atmosphere and circulating flowing are controlled selectively in accordance with a comparision result of the detecting temperature of the grains with a set temperature, upon shifting the grains from a drying section into a cooling tank. CONSTITUTION:A grain drying device is constituted of a grain drying unit 4, provided with a burner 10 and the like, and a natural cooling tank 5, equipped with an elevator 15, a shifting screw trough 22 and the like on the upper surface thereof, which are built up ventically. Grains are supplied from a hopper 53 into the grain drying unit 4 through a charging conveyer 52, the elevator 15, a communication pipe 18 and a circulating and shifting trough 20. In this case, a grain temperature upon finishing drying is detected. When the detected temperature is higher than a first set value, the grains are circulated in the grain drying unit 4 and, thereafter, are shifted into the natural cooling tank 5. On the other hand, when the detected temperature is lower than the first set value and higher than a second set value, lower than the first set value, ventilating drying, effected only by atmosphere, is effected and, thereafter, the grains are shifted into the natural cooling tank 5. When the detected temperature is lower than the second set value, the ventilating operation is stopped.

The grain drying unit 4 is circulated for a predetermined time or a predetermined number of times (step 170). When the predetermined time or the predetermined number of times has been completed (step 180), the switching valve 17 is switched to the opening b side supply and the grain is transferred to the cooling tank 5 (step 190). As a result, when the grain temperature is high, ventilation is performed to promote drying, which in turn prevents overdrying.

When TG <B in step 200, the suction fan 9 is stopped (step 230) and immediately moved to the cooling tank 5. This is because if the grain temperature is low, moisture may be absorbed depending on the conditions of the outside air, and it is desirable to avoid ventilation. Grain cooling in the cooling tank 5 is performed in a stationary state, but the grain temperature is reduced and moisture unevenness is corrected, and when the temperature approaches room temperature, it is appropriately taken out and transferred to the hulling process. During the cooling process, the open / close panel plate 32 may be opened or a ceiling fan or the like outside the drawing may be driven to prevent stuffiness when necessary.

Is circulated in the grain dryer 3 and transferred to the post-cooling tank 5, and when the detected grain temperature is equal to or lower than the first predetermined value and equal to or higher than a second predetermined value B lower than the predetermined value, the outside air is blown for a predetermined time. A method of cooling in a grain drying device in which the grain is dried by ventilation and then transferred to the cooling tank 5, and when the detected grain temperature is not more than the second predetermined value B, the ventilation operation is stopped and the grain temperature is transferred to the cooling tank 5.
