Abstract
Description
Technical Field
[0001] This utility model relates to the field of walnut production and processing technology, and in particular to a walnut washing and drying device. Background Technology
[0002] Walnuts, also known as Persian walnuts or walnuts, are a plant of the Juglandaceae family. Along with almonds, cashews, and hazelnuts, they are considered one of the world's four most famous dried fruits. Walnut kernels are rich in nutrients, containing 15-20 grams of protein per 100 grams, a relatively high amount of fat, 10 grams of carbohydrates, and essential trace elements and minerals such as calcium, phosphorus, and iron, as well as various vitamins such as carotene and riboflavin, all beneficial to human health. They are one of the most popular nuts among the general public.
[0003] From harvesting to the final product sold on the market, walnuts currently undergo a process of selection, shelling, washing, dehydration, and drying. Because there is still juice residue on the walnuts after the green husk is removed, the walnuts need to be washed again after shelling. At the same time, the washed walnuts are initially dried and dehydrated. If there is a lot of moisture on the surface of the walnuts, black spots and discoloration are likely to appear on the surface of the walnuts after they are heated in the drying room, which will affect the quality of the walnuts. However, the walnut washing machines on the market only have the function of washing walnuts and do not have the function of initially drying and dehydrating the moisture on the surface of the walnuts.
