Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a pine nut grinding device. Background Art

[0002] In the field of nut processing, pine nuts, as a nutritious food, are deeply loved by consumers. However, during the process of picking, drying, and transportation, impurities such as dirt, dust, and branch and leaf fragments are often easily attached to the surface of pine nuts, which not only affects the appearance quality of pine nuts, but also may pose a potential threat to the health of consumers. Therefore, polishing and grinding pine nuts to remove surface impurities and improve the overall quality of pine nuts has become an important part of the nut processing industry.

[0003] Traditional pine nut polishing and grinding methods are mostly done manually or by simple mechanical methods. These methods have disadvantages such as low efficiency, uneven polishing effect, and easy damage to the surface of pine nuts. With the advancement of technology and the improvement of consumers' requirements for food quality, traditional polishing and grinding methods can no longer meet market demand. Therefore, the development of an efficient, uniform, and low-damage pine nut polishing and grinding device has become an urgent problem to be solved in the nut processing industry.

[0004] At present, although there are some pine nut polishing and grinding equipment on the market, these equipment still need to be improved in terms of polishing effect, processing speed, and ease of operation. For example, some equipment is prone to damage pine nuts during the polishing process, resulting in pine nuts breaking or surface scratches; other equipment has the problem of uneven polishing, resulting in impurities remaining on the surface of pine nuts. In addition, most equipment is complicated to operate and requires professional personnel to operate and maintain, which increases the cost of use.

[0005] Therefore, this patent aims to provide a pine nut polishing and grinding device, which can achieve efficient, uniform, and low-damage polishing and grinding treatment of the pine nut surface by optimizing the design and parameter setting of the polishing and grinding mechanism.
