Description

Technical Field

[0001] This utility model relates to the field of oil pressing and grinding technology, and in particular to a grinding device for oil pressing. Background Technology

[0002] Traditional oil pressing emphasizes craftsmanship, which relies on accumulated experience. Each step of the traditional wooden oil press process is meticulously executed, with its own key techniques, such as controlling the heat, pressure, and time. Today, the complex process of traditional oil pressing has not disappeared with the passage of time; instead, it has undergone continuous improvement and refinement. Because it fully preserves the original aroma and nutritional components of the oil, it has become popular in the market and is deeply loved by consumers.

[0003] Traditional stone mills or mechanical grinding devices may require a large amount of power to drive, resulting in high energy consumption and increased production costs. Some devices, such as small stone mills, have low grinding efficiency, making it difficult to meet the needs of large-scale production and affecting the overall oil extraction efficiency. The particle size after grinding is inconsistent, which may lead to unstable oil yield or differences in oil quality during subsequent pressing. To address these issues, we propose a grinding device for oil extraction. Utility Model Content
