Cereal drying mechanism

Abstract

The invention discloses a cereal drying mechanism which comprises a drying part and a drying lower body. The drying part is composed of side plates and mesh plates. The mesh plates are spliced into a closed type tower-shaped structure and evenly inserted in the drying part along the side plates to divide the drying part into at least five semi-closed grooves. Through holes are evenly distributed in the mesh plates and are each of an elliptic or kidney-shaped structure. The open hole caliber of each through hole ranges from 1.5 mm to 2.5 mm. A hot air outlet is formed in one end of each side plate and provided with a splash prevention plate. After the structure is adopted, without changing the aperture ratio, it is avoided that cereals leak out of meshes to cause cracks and breakage; the universality of the drying part is enhanced, cereals can be effectively prevented from being sucked out, air volume is not influenced, impurity removal can not be influenced either, cereals are blocked by the prevention plates and can not be sucked out, and impurities of cereals can fall down to a lower body through the drying part and then be brought out.

Description

technical field [0001] The invention relates to a grain drying equipment, in particular to a drying mechanism in a material internal circulation dryer. Background technique [0002] At present, during the drying and circulation process of the low-temperature grain dryer, the grain is dried through the drying section. The mesh plate must not only ensure that the grain does not leak, but also ensure that the grain has a sufficient area to contact the hot air when passing through. The size of the opening And the opening rate is very important. The existing mesh size is ∮2-P3.5, and the entire mesh plate is distributed in an equilateral triangle. Generally, grains cannot pass through, but the long-grain grains in Guangdong and Guangxi in southern my country are special compared to varieties. , may pass through the mesh plate or generally pass through, resulting in leakage of rice or grains being cut off at the middle, increasing brokenness.

Problems solved by technology

[0002] At present, during the drying and circulation process of the low-temperature grain dryer, the grain is dried through the drying section. The mesh plate must not only ensure that the grain does not leak, but also ensure that the grain has a sufficient area to contact the hot air when passing through. The size of the opening And the opening rate is very important. The existing mesh size is ∮2-P3.5, and the entire mesh plate is distributed in an equilateral triangle. Generally, grains cannot pass through, but the long-grained grains in Guangdong and Guangxi in southern my country are special compared to varieties. , may pass through the screen or generally pass through, resulting in leakage of rice or grains being cut off at the middle, increasing brokenness. Due to the large variety of grains, the most common are original glutinous rice and long-grain rice. The difference is large, so the current mesh is not suitable for long-grain rice. Long-grain rice will drill out of the mesh, causing grain breakage and broken waist, which will affect the quality. Moreover, the existing hole position is round, which will easily cause mesh blockage and affect the quality of rice. Ventilation and drying effect

[0003] In addition, when the low-temperature grain type grain dryer is in the drying section, when the grain enters the drying section and reaches the lower body, some grains will be sucked out due to the fan, causing waste, and the screen cannot be directly screened at the bottom. If it is blocked, it will cause accumulation of impurities and insufficient air volume
