[0002] The industrial chili grinding process includes raw material processing, grinding, post-processing, and packaging and storage. In the raw material processing stage, large quantities of chilies need to be processed industrially, so the equipment for washing, drying, and removing impurities is larger, such as drum washing machines and belt dryers. Then there's the grinding equipment; commonly used industrially include hammer mills and air jet mills. These machines are highly efficient and suitable for large-scale production. Applications of chili grinding include food processing, for producing chili sauce, instant noodle seasonings, hot pot bases, and pickled foods, where different products have different particle size requirements; and condiment manufacturing, where chilies are used as raw materials for independent seasonings or compound spices, with standardized grinding controlling the consistency of spiciness.

[0021] 3. The drive motor drives the processing grinding disc and the extrusion cam to rotate synchronously through the first sprocket, the transmission chain and the second sprocket, forming a power integrated system. The inclined surface design of the annular fixed grinding block and the processing grinding disc expands the grinding contact area, guides the raw material to gather towards the center and grind it fully, improves grinding efficiency, and ensures stable equipment operation and low energy consumption.
