[0002] Dehydrated vegetables, also known as rehydrated vegetables, are dried vegetables made by washing and drying fresh vegetables to remove most of their water content. The original color and nutritional components of the vegetables are basically preserved. They are easy to store and transport, and can effectively regulate the peak and off-peak seasons of vegetable production. When eating, they can be rehydrated by soaking them in clean water, while retaining their original color, nutrition and flavor. Drying is an essential step in the production of dehydrated vegetables, so we need hot air drying equipment for dehydrated vegetables.

[0003] Chinese patent application publication number CN213992372U discloses a hot air drying device for dehydrated vegetables. This hot air drying device for dehydrated vegetables, through the arrangement of a wind power mechanism and a heating mechanism, can generate a large amount of hot air to dry the vegetables, preventing poor drying results and achieving the desired drying effect.

[0004] Although the above-mentioned patented solution can use hot air to dry vegetables, the drying device in the above-mentioned patent is not convenient to adjust the air direction to dry vegetables from multiple angles. At present, most drying devices use a wind mechanism that is fixed at the bottom of the equipment, and the direction of the wind is fixed. There are spaces between vegetables that cannot be blown, resulting in low drying efficiency.

[0005] Therefore, a hot air drying device for dehydrated vegetables is proposed here. Utility Model Content
