Abstract

The invention discloses a self-circulation multi-layer slat dryer, which comprises a feeding and discharge device (1), a drying chamber (3) and a wind network system (4), wherein the wind network system (4) is used for supplying hot wind to the drying chamber (3) to heat materials. The self-circulation multi-layer slat dryer is characterized by further comprising a multi-layer flat conveyor device (2), a lifter (5) and a control system for controlling the dryer. In addition, the invention also discloses a self-circulation segmented drying method. The self-circulation multi-layer slat dryer and the self-circulation stepwise drying method have the advantages of realizing segmented temperature and humidity control, ensuring dehydration is performed according to the laws of a baking curve in a material drying process, ensuring the quality of dried products, ensuring the materials are uniformly heated because the multi-layer slat conveyor device is used in combination with the lifter to function in turning the materials over in the self-circulation process of the materials, meeting the materials of different characteristics, setting the temperature, humidity and time of each segment according to the characteristics of the materials and realizing discharge at any time, along with wide application range, high drying quality and capability of realizing automatic production.

Description

technical field

[0001] The invention relates to a self-circulating multi-layer flap dryer, which belongs to the field of drying machinery. In addition, the present invention also relates to a self-circulation segmental drying method. Background technique

[0002] The existing drying of fruits and vegetables mainly relies on natural drying, kiln drying and other methods, and the more advanced ones use tunnel dryers with drying cars or belt dryers.

[0003] It takes a long time to use natural drying, kiln drying, etc., which is labor-intensive and difficult to realize automation. However, it is difficult to realize segmented temperature and humidity control for belt dryers, and it is difficult to formulate different drying methods according to different material characteristics. , As a result, the quality of dried products is generally poor, the surface is severely wrinkled or even burnt, the taste is poor, and the nutritional loss is serious, making it difficult to enter the...
