AI Technical Summary

Technical Problem

Cocoa beans tend to accumulate during the ultrafine grinding process, which prevents liquid nitrogen from making sufficient contact with the cocoa beans, resulting in uneven cooling and affecting the grinding effect.

Method used

A cocoa bean ultrafine grinding and powdering device was designed, including a feeding component, a pretreatment component, and a support component. The device uses liquid nitrogen vaporization to uniformly cool the cocoa beans and accelerates the feeding through vibration and hydraulic devices to ensure uniform contact and stable conveying of the cocoa beans with liquid nitrogen.

Benefits of technology

This method achieves uniform contact between cocoa beans and liquid nitrogen, ensuring a cooling effect, improving crushing efficiency and feeding speed, and enhancing the stability of the crushing process.
