Description

TECHNICAL FIELD

[0002] The drying device for food production is a very important equipment in the field of food processing, and its main function is to remove the excess moisture in food to achieve the purpose of prolonging the shelf life, improving the taste, facilitating storage and transportation.

[0003] The existing drying device generally rotates the stirring assembly to continuously turn the food in the drying cavity, thereby increasing the contact area and frequency of the food and hot air, improving the drying efficiency and effect. When processing conventional-shaped foods such as blocks and granules, this stirring type drying device can achieve relatively uniform drying and meet the production requirements. However, when facing the drying needs of long strip-shaped foods, due to the characteristics of long length and different flexibility of long strip-shaped foods, it is difficult to accurately control the stirring intensity and direction when the stirring assembly stirs them. If the stirring intensity is too large, it is easy to cause the long strip-shaped foods to be stirred off or broken, which seriously damages the morphological integrity of the foods. If the stirring intensity is too small, the foods cannot be fully contacted with the hot air, and the ideal drying effect cannot be achieved.

[0004] For some long strip-shaped foods with high requirements for morphological retention, such as beans and asparagus, the morphological integrity after drying directly affects the appearance quality, market value, and subsequent processing and sales of the products.
