Non-abrasive coffee bean comminuter

Abstract

The invention discloses a non-abrasive coffee bean comminuter. The non-abrasive coffee bean comminuter comprises a conveying channel, a feed opening, a refrigeration system, a comminuting system and a separation screening system, wherein the refrigeration system is used for performing low temperature pretreatment on coffee beans; the comminuting system comprises an air flow blowing device communicated with the conveying channel, and a comminuting component which is arranged in the conveying channel, is positioned on the lower part of the air flow blowing device and is positioned in the center of the conveying channel; the coffee beans in the conveying channel bump to a windward side of the comminuting component along with the air flow and are comminuted into coffee granules or coffee powder which continuously flows to the lower part through a gap between the conveying channel and the comminuting component; and the separation screening system is used for classifying and collecting the coffee granules or the coffee powder. The non-abrasive coffee bean comminuter comminutes the coffee beans in a non-mechanical extrusion and friction mode, and can reduce the friction between the coffee beans and a metal part to avoid pollutions caused by metal scraps; besides, the coffee powder processed by the non-abrasive coffee bean comminuter can better keep the fragrance of the coffee beans.

Description

technical field [0001] The invention belongs to the field of industrial processing of coffee beans, in particular to an industrial non-grinding coffee bean crushing equipment. Background technique [0002] The process of industrially processing coffee beans is usually: fresh coffee beans are washed and dried first, then shelled, and then the coffee beans are roasted, and the roasted coffee beans are ground into powder by crushing equipment to make coffee powder or foam coffee etc. At present, most of the industrial equipment for crushing coffee beans still adopts the mechanical crushing method. For example, the existing coffee grinder uses the grinding center to mechanically squeeze the coffee beans under the action of external force to form powder. body. Due to the large amount of industrially processed coffee beans, the wear of the grinding center is serious, so the selection of the material for the grinding center of the bean grinder is critical, which directly affects ...

AI Technical Summary

Problems solved by technology

During the processing of the existing coffee grinder, the friction between the grinding core and the coffee beans generates serious heat, so the coffee beans are heated indirectly during the grinding process, causing the aroma powder to be released in advance, which affects the quality of the coffee after cooking. Fragrance, poor quality will obviously feel the temperature of coffee powder is higher

Based on these problems, many people have devoted themselves to the improvement of coffee bean grinding methods, which have improved the grinding efficiency to a certain extent, but they have always treated the symptoms but not the root cause.
