Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coffee bean back pressure, in particular to a coffee fruit non-peeling back pressure processing equipment. BACKGROUND

[0002] Coffee beans refer to plant fruits used to make coffee. For many years, Nestle and Starbucks have adopted the ordinary commodity bean procurement mode of bulk commodity bean procurement standards, which has prompted the processing mode of Yunnan coffee beans to generally adopt mechanical semi-water washing, which not only causes water pollution but also limits the improvement of Yunnan bean flavor. Under the dual pressures of price restriction due to flavor loss and environmental protection, many coffee companies in Yunnan are also trying to break through and have created some high-quality sun-dried beans, tightly processed beans and special flavor coffee beans through micro-batch anaerobic fermentation in recent years. The quality and price have been greatly improved, and the reputation of Yunnan coffee has also begun to be recognized by domestic coffee shops, but ultimately it is difficult to form a sustainable and stable supply chain due to the lack of scale.

[0003] At present, the existing back pressure processing equipment only uses a hot air blower to dry and back pressure the coffee beans in the drying pool when processing coffee beans, so that the coffee beans are heated and dried. However, since the existing equipment accumulates a large number of coffee beans together during back pressure processing of coffee beans, the hot air blower cannot uniformly heat and dry the coffee beans, resulting in some coffee beans becoming damp, which reduces the quality of the finished product. Moreover, the existing equipment does not have a sorting function for coffee beans and needs to be sorted after back pressure processing. In addition, during back pressure processing, the coffee bean skin dries and cracks, and most existing equipment does not have a skin collection device.

[0004] Therefore, it is necessary to design a new equipment to solve the above problems, specifically a coffee fruit non-peeling back pressure processing equipment. SUMMARY
