Grain drying machine with automatic classification function

Abstract

The invention belongs to the field of grain drying, and particularly discloses a grain drying machine with an automatic classification function. The grain drying machine comprises a feeding hopper, a measuring device, drying bins and a grain classifier. The feeding hopper comprises a storage hopper and a feeding pipe, the lower end of the storage hopper is connected with the feeding pipe, the measuring device is installed on the pipe wall of the feeding pipe, and the lower end of the feeding pipe is connected with the grain classifier; and the number of the drying bins is multiple, and the multiple drying bins are located below the grain classifier.

Description

technical field [0001] The invention belongs to the field of grain drying, in particular to an automatic sorting grain dryer. Background technique [0002] With the improvement of the degree of agricultural mechanization, in order to ensure the timely and effective drying of grain. Most of the grain is no longer dried by the traditional drying method, but is dried by a more convenient drying device. The dryers currently on the market can dry a large amount of grain at one time, and the drying process is more efficient than the traditional sun drying. [0003] However, due to the high drying efficiency, the grain will be dehydrated rapidly in a short period of time. If the drying time and temperature cannot be accurately controlled, it will easily lead to excessive dehydration and inactivation of the grain during drying. Moreover, due to the drying of large batches, the moisture content of the grain is different to a certain extent, but in the same environment, the dehydrat...

Problems solved by technology

[0003] However, due to the high drying efficiency, the grain will be dehydrated rapidly in a short period of time. If the drying time and the temperature cannot be accurately controlled, it will easily lead to excessive loss of water and inactivation of the grain during drying.

Moreover, due to the drying of large batches, the moisture content of the grain is different to a certain extent, but in the same environment, the dehydration speed of the grain is the same, and drying in large quantities will cause the moisture content of the dried grain to be different.
