A device for peeling coffee cherries using bionic principles

Abstract

The present invention provides a device for peeling coffee cherries by using a bionic principle, belongs to the field of environmental control of high-altitude characteristic agricultural production and processing processes and solves problems that a large amount of water is wasted in the coffee production and processing processes; the peeling rate of the coffee cherries is low; and the generatedwaste is difficult to be reused. The mature coffee cherries are put on a toothed conveyor belt with concave pits to be conveyed to a corresponding position of a bionic finger; the bionic finger simulates movement of human hands under actions of a cam and a spring to complete extrusion and peeling of the coffee cherries; the peeled coffee cherries are sent to a front collecting device; and coffee cherry peels are sent to the collecting device by the toothed conveyor belt for resource utilization. The device is used to peel the coffee cherry peels, can save a lot of rinsing water required by a traditional peeling method and also improves the peeling efficiency of the coffee. The peeled peels are convenient for resource utilization. The device realizes water saving in coffee harvesting and processing process, improves peeling efficiency of the coffee cherries, and realizes environmental friendliness and waste resource utilization.

Description

technical field [0001] The invention relates to a device for peeling coffee cherries by utilizing the bionic principle, and belongs to the field of environment control in characteristic agricultural production and processing processes. Background technique [0002] The production process of coffee beans is mainly composed of coffee cherries dehulling, coffee bean drying, grinding off glumes, cleaning and bagging. The large amount of wastewater generated by coffee cherries dehulling has become a major problem in the post-harvest processing of coffee cherries. [0003] At present, the methods of mechanical friction and extrusion are widely used for dehulling coffee cherries, and the coffee rinds and coffee beans are separated by mechanical force. Stay to achieve the separation of the peel from the coffee beans. [0004] In the process of mechanical separation, due to the uneven size of coffee cherries and unclean peeling, some coffee cherries have not been separated from the ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the above-mentioned defects in the prior art, and to provide a device that uses mechanical bionic finger movements to separate coffee beans and peels according to the principle of peeling off the peels of coffee peels with human fingers, which belongs to the precision agricultural technology. The separation of coffee beans and peels can be realized without water washing, which not only saves washing water but also improves the peeling rate, and simultaneously solves the environmental pollution caused by the washing water of peels in the coffee production process and the problem that the coffee peeling is not clean and affects the quality of coffee beans
