Description

TECHNICAL FIELD

[0001] The utility model relates to a drying machine more specifically, it relates to a mixed grain drying machine. BACKGROUND

[0002] The mechanization of grain drying is more important than that of field operation, and it is an important guarantee condition for high yield and high harvest of grain. Grain drying machine becomes the inevitable choice. In order to speed up the drying process, mixed grain drying will be carried out, that is, the process of drying multiple grains (such as rice, wheat, barley, corn, rapeseed, soybean, etc.) at the same time. Mixed drying can make full use of the capacity of the drying machine, reduce the drying batch, and improve the drying efficiency. Especially in large farms or grain processing plants.

[0003] The existing equipment with good hot drying effect is vertical hot air drying machine, which is dried by hot air when falling. Grains can be roughly divided into large grains, medium grains and small grains according to their length and width. Large grains include long grain rice (such as indica rice), because the grains are relatively long and wide. In addition, some varieties of wheat, corn and other grains may also be classified as large grains due to their large grains.

[0004] Medium grain (according to some classification standards, the length of the grain is between 5.51 and 6.6 mm, and the length-width ratio is between 2.1 and 3.0) includes medium-sized wheat, corn and other grains.

[0005] Small grain includes short grain rice (such as japonica rice, with shorter grain length and length-width ratio less than 2.0). In addition, millet, oat, barley and other grains.

[0006] Through implementation, excessive drying of grains will make the moisture content lower than the appropriate range for safe storage. This not only causes the grains to lose their original taste and nutritional value, but also increases the fragility of the grains, making them more susceptible to damage during subsequent processing and storage, and even cracking and bursting.

[0007] However, due to different weights, different moisture contents, different falling speeds and other factors, different sizes of grains will be affected by hot air to different extents. Therefore, the existing drying machine only has a single drying function, and cannot achieve targeted drying effect for different specifications of grains. CONTENT OF THE UTILITY MODEL
