Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain processing, in particular to a grain drying device. Background Art
[0002] Grain needs to be dried before storage. Grain usually contains a high amount of moisture, which is not only difficult to store, but also prone to mold and deterioration, thus affecting the quality and food safety of the grain. Drying can effectively reduce the moisture content of the grain to meet the standards for safe storage, while also helping to maintain the quality and taste of the grain.
[0003] The existing patent announcement number CN208026000U discloses a grain dehydration and drying device, which includes an exhaust spring and a push rod. First, the push rod is pushed to drive the bracket and the bottom plate to move, so as to drive the four groups of legs to move and the four groups of rollers to rotate, so as to drive the device to move to the position required by the user. The baffle cover is opened to place the food particles to be dehydrated and dried in the placement groove and the baffle cover is closed. The placement rack is pushed into the working chamber, the door panel is closed and the limit plate is rotated. The motor drives the transmission shaft and the rotating disk to rotate at the same time. The grain particles in the placement groove accelerate water loss under the action of centrifugal force. When the gas pressure in the working chamber is too large, the gas diffuses outward, driving the exhaust baffle to move longitudinally, so as to drive the exhaust spring to undergo elastic deformation, thereby discharging excess gas.
[0004] When the above device is drying grain, the grain needs to be taken out and dried repeatedly, which is time-consuming. In addition, it takes a long time to dry the grain piled together, which will cause the outer layer of the grain to be too dry while the moisture in the inner grain is not dry. In addition, some sand and gravel will be mixed in the grain, which is difficult to clean.
[0005] In view of the above problems, a grain drying device is proposed. Utility Model Content
