Description

Technical Field

[0001] The utility model relates to the technical field of cashew nut drying, in particular to a drying device for cashew nut production. Background Art

[0002] Cashew kernels are high in fat, approximately 47%. These fats are primarily unsaturated fatty acids, such as oleic acid and linoleic acid, which are beneficial to human health. Oleic acid helps lower blood cholesterol levels, while linoleic acid is an essential fatty acid that plays a role in maintaining the normal function of cell membranes and regulating physiological metabolism. Cashew nut drying is a key step in cashew processing.

[0003] At present, when cashew nuts are dried, they are spread on a conveyor belt and dried by hot air. However, during the drying process, the internal temperature of the drying chamber needs to be adjusted and alternated between hot and cold, which causes the conveyor belt to easily relax or tighten under the hot and cold conditions, thereby reducing the transmission efficiency. Secondly, when drying cashew nuts, hot air is mostly blown downward from the upper part, resulting in low drying efficiency. Therefore, it is necessary to improve a drying device for cashew nut production to solve the above problems. Utility Model Content
