Description

Technical Field

[0001] The utility model relates to the technical field of cocoa powder processing, and belongs to a raw cocoa powder grinding device. Background Art

[0002] Cocoa powder is a powdery substance processed from cocoa beans taken from the fruits of cocoa trees through multiple processes. Cocoa powder has a strong cocoa aroma and can be used to make high-end chocolates, beverages, milk, ice creams, candies, pastries and other cocoa-containing foods. Cocoa powder contains ingredients such as caffeine, theobromine, dopamine and catechins, which have the effects of stimulating the central nervous system, improving alertness and attention, and reducing blood pressure.

[0003] During the production process of cocoa powder, grinding is a key process, which directly affects the quality and taste of cocoa powder. The common cocoa powder grinding equipment on the market generally adds cocoa beans directly into the grinding tank for grinding and refinement. However, this grinding method has low grinding efficiency, and the fineness and uniformity of the ground cocoa powder are poor, thus the taste and quality cannot be guaranteed. In addition, for common grinding devices, the grinding gap formed between the grinding disc and the grinding pad is inconvenient to adjust. In order to ensure the fineness of cocoa powder, the grinding disc and the grinding pad need to be close enough, which is not easy for granular cocoa beans to enter the grinding gap, resulting in a long grinding time. Therefore, in view of these problems, a raw cocoa powder grinding device is proposed. Summary of the Utility Model
