Description

Technical Field

[0001] This utility model belongs to the field of walnut cleaning technology, specifically a walnut cleaning device for walnut powder processing. Background Technology

[0002] Walnuts, also known as Persian walnuts or walnuts, belong to the Juglandaceae family. Along with almonds, cashews, and hazelnuts, they are known as the world's four famous dried fruits. Walnut kernels are rich in nutrients, containing 15-20 grams of protein, a relatively high amount of fat, and 10 grams of carbohydrates per 100 grams. They also contain essential trace elements and minerals such as calcium, phosphorus, and iron, as well as various vitamins such as carotene and riboflavin. They are beneficial to the human body and are one of the most popular nuts among the general public.

[0003] The specific design and structure of walnut washing devices for walnut powder processing may vary depending on different manufacturers and application requirements, but generally they include the following key components: outer shell, washing tank, water pump, and water inlet pipe. The outer shell is the external casing of the device, which serves to house and protect the internal components. It is usually made of materials such as metal or plastic and has a certain degree of sealing to prevent water from splashing out during the washing process. The washing tank is divided into a horizontal section and a lifting section. The horizontal section is used for washing the walnuts, and the lifting section is used to transport the washed walnuts to the drying area. The front end of the washing tank is equipped with a feeding plate, and the rear end is equipped with a discharge plate to facilitate the loading and unloading of walnuts. The water pump draws water from the storage tank to the water inlet pipe, which is located directly below the conveying mechanism in the horizontal section of the washing tank, providing a water source for washing.

[0004] The existing walnut washing equipment for walnut powder processing has certain drawbacks. It can only clean walnuts once; if the cleaning is incomplete, they need to be put back into the equipment for another wash, increasing workload and time costs for walnut powder production. Furthermore, the washed walnuts may contain residual impurities, requiring separate sorting, which significantly impacts the production schedule. Additionally, the washed walnuts cannot be used directly for walnut powder production; they need to be air-dried separately to remove surface water, further affecting production progress.

[0005] To address the above problems, a walnut cleaning device for walnut powder processing is proposed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a walnut cleaning device for walnut powder processing.
