Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and in particular relates to a high-efficiency drying machine for dehydrated vegetables. Background Art

[0002] The processing of dehydrated vegetables generally involves washing, dehydration, peeling and seed removal (optional step), slicing or dicing, steaming, cooling, dehydration, and drying. In the dehydration process after washing, avoid squeezing, because vegetables that have not been steamed at high temperatures are generally brittle and easily damaged or broken by external forces, especially beans and peppers. Therefore, this process generally uses the height difference of the conveyor belt to allow the water to fall naturally during transportation. For leafy vegetables such as cabbage that are soaked in water, manual centrifugation can also be used to slightly dry the water. However, in the dehydration process after steaming and before drying, there is no need to worry about the problem of vegetable breakage. The vegetables become relatively soft after steaming and can withstand a certain amount of external force.

[0003] Existing vegetable dryers generally require the dehydrated vegetables to be clamped by vegetable net clips, and then the vegetable net clips are placed in the dryer for drying. After drying, the net clips are taken out and the dried vegetables are unloaded, which results in a waste of a lot of manpower, material resources and time, is not conducive to continuous production, and further affects the drying efficiency.

[0004] To this end, the applicant has conducted useful explorations and attempts and found solutions to the above problems. The technical solutions to be introduced below were produced in this context. Utility Model Content
