Description

Technical Field

[0001] The utility model relates to the technical field of seed drying equipment, in particular to a seed drying and dehydrating device. Background Art

[0002] Newly harvested seeds, especially those harvested on rainy days, have high water content, strong physiological functions, and release more heat through respiration, so they are prone to heat and mildew, and quickly lose their seed value. In order to ensure the safe storage of seeds and their vitality, they must be dried and dehydrated. The existing drying method is basically static drying, but the static drying method has the disadvantages of long drying time and low drying efficiency. When the existing drying equipment is used for drying, the wet seeds are directly dried, which takes a long time and wastes a lot of energy. Therefore, it needs to be improved. Utility Model Content
