Description

Technical Field

[0001] The utility model relates to the technical field of drying treatment, in particular to a hot air drying machine for waxing the surface of fruits. Background Art

[0002] Fruit waxing is a common preservation method that aims to extend the shelf life and increase the value of the product by coating the surface of the fruit with a layer of wax. This technology can not only prevent the evaporation of water from the fruit, but also effectively block the invasion of external microorganisms and pollutants into the flesh, improving the storage and preservation effect. In addition, the surface of the waxed fruit needs to be dried with hot air. After the hot air drying, the surface of the fruit presents a bright luster, which significantly improves the appearance quality of the product. The wax layer can protect the fruit skin from external friction and scratches to a certain extent, reduce mechanical damage during transportation and storage, and the wax layer can be further fixed on the surface of the fruit to reduce water loss.

[0003] The existing hot air drying device for waxed fruit surface cannot evenly dry the waxed fruit surface with hot air, resulting in the wax layer falling off. Moreover, after the hot air dries the waxed fruit surface, it is directly discharged, causing waste and increasing production costs. Therefore, it is of great practical significance to develop a hot air drying machine that can evenly dry the wax layer on the fruit surface. Utility Model Content
