Layered temperature and time control multi-layer mesh belt type camellia seed drying device

Abstract

The invention discloses a layered temperature and time control multi-layer mesh belt type camellia seed drying device, and belongs to the technical field of agriculture and forestry product drying equipment. The device mainly structurally comprises a box body, a camellia seed conveying mechanism, an air volume adjusting mechanism, a temperature layered compensation mechanism, a layered air supplypipeline, a variable-aperture porous box, a transmission mechanism and the like. The layered driving, temperature compensating and air volume adjusting mechanism is provided, the operation speed, thetemperature and the air volume can be independently adjusted and controlled in a layered mode, and control can be accurately conducted according to a camellia seed drying process curve; and the variable-aperture porous box supplies air from the side surface and discharges air from the top, so that the temperature and air speed distribution uniformity is ensured, the outlet speed is reduced, air isin full contact with materials, and the drying quality of camellia seeds can be ensured.

Description

technical field [0001] The invention relates to the technical field of drying equipment for agricultural and forestry products, in particular to a multi-layer mesh belt-type camellia seed drying device with layered temperature and time control. Background technique [0002] Drying is an important process in the post-treatment process of camellia oleifera seeds. After drying, camellia oleifera seeds have the advantages of easy storage and improved quality. There are two main forms of moisture in Camellia oleifera seeds: free water and bound water. In the drying process, the free water evaporates first, and the internal bound water migrates to the surface to evaporate. However, the temperature and time required for the free water and bound water to reach the evaporating conditions are different. Therefore, in the drying process, different temperatures are required. Intervals and drying times vary. [0003] At present, the equipment for the drying process of camellia oleifera...

Problems solved by technology

However, the multi-layer drying belt of this device is driven by a motor and moves at the same time, so the running speed of a single layer cannot be controlled, and because the air supply is uniform, the temperature of each layer cannot be independently controlled

[0006] The utility model patent with the publication number CN210569778 discloses a multi-layer belt dryer with partition control. The device divides the drying area into multiple areas by setting partitions, and changes the air volume by changing the diameter of the air pipe. This method can only Several air volumes can be changed, and the air duct needs to be disassembled, which cannot be changed at any time; a heater is installed in each area to control the temperature, which can only raise the low temperature to a high temperature, and cannot lower the high temperature to a low temperature; at the same time, when the device is running For synchronous movement, the speed of individual zones cannot be controlled
