Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain drying, especially relates to a grain dryer with uniform drying. BACKGROUND

[0002] According to statistics, the loss of grain in the processes of threshing, airing, storage, transportation, processing and consumption is as high as about 18%, far exceeding the standard of 5% stipulated by the Food and Agriculture Organization of the United Nations, and the loss caused by mildew and germination due to the fact that the grain cannot be dried in time or does not reach the safe moisture content is as high as 5% every year, which is a huge waste. Therefore, drying the harvested grain and controlling its moisture content below the safe moisture content is an important measure to reduce the loss of grain.

[0003] Therefore, the grain usually needs to be dried by a dryer before storage, such as the grain dryer disclosed in the utility model with the announcement number CN211476575U, which comprises a shell assembly and a drying assembly. The shell assembly comprises a shell, a top cover, two feed hoppers, a collecting device and a control console. The top cover is installed on the top of the shell by bolts. The two feed hoppers are located on the top of the top cover. The collecting device is located on the inner wall bottom of the shell. The control console is located on the front surface of the shell. When the grain is dried by the grain dryer, the grain is fed into the shell from the feed hoppers. The telescopic cylinder is started to drive the top plate to rise and match with the baffle to form a closed space. The grain falls into the closed space. The three-phase asynchronous motor is started to drive the mixing frame to rotate slowly. At the same time, the external equipment generates hot air which is fed into the gas storage block from the air inlet and then is discharged by the air diffuser, so that the grain can be fully contacted with the hot air for drying.

[0004] However, when the hot air is transported by the air inlet in the above-mentioned application, the grain accumulated in the shell is heated from top to bottom, which is not uniform, resulting in poor drying effect and affecting the drying efficiency. Therefore, a grain dryer with uniform drying is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS
