[0002] Sweet potato, also known as sweet potato, sweet potato, yam, etc., is a perennial twining vine of the Dioscoreaceae family and Dioscorea genus. Its tuber has many branches at the top, the stem is left-handed, with thorns at the base and T-shaped soft hairs; the leaves are heart-shaped, with T-shaped long soft hairs, especially on the back, and the petioles have thorns; the perianth is shallow cup-shaped and covered with soft hairs; the fruit is less mature and triangular. The flowering period is in early summer.

[0003] The drying of sweet potatoes has the beneficial effects of long-term preservation, not easy to be affected by moisture, and more convenient for storage and transportation. In addition, drying can effectively remove excess water in the sweet potatoes, so that the nutrients such as starch and protein in the sweet potatoes can be concentrated, thereby improving their nutritional value and taste. The dried sweet potatoes will have a richer taste and unique flavor. However, the conventional drying device blows hot air from the top to dry the sweet potatoes in the device. When only one layer of sweet potatoes is dried, the effect is very good. When drying multiple layers of sweet potatoes, it is easy to cause uneven drying effect. Only the sweet potatoes on the top layer have the best drying effect, which greatly reduces the drying efficiency. Utility Model Content

A new type of drying device for sweet potato processing is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
