Description

Coffee cherry crust breaker Technical Field The utility model belongs to the technical field of coffee processing equipment, and particularly relates to a coffee cherry shell breaking machine. Background In the coffee fruit processing flow, the shell breaking process is a key link for obtaining coffee beans, and the technical level of the process directly influences the quality and the production benefit of the coffee beans. Currently, small-scale coffee processing enterprises or traditional workshops mostly adopt a manual shell breaking mode. Manual operation can avoid damaging coffee beans to a certain extent through experience, but the production efficiency is extremely low, the number of coffee cherries processed per hour by each person is limited, and the requirement of large-scale industrial production is difficult to meet. Moreover, long-time repeated labor is easy to cause fatigue of workers, the risk of misoperation is increased, meanwhile, the labor cost is continuously increased, and the profit margin of enterprises is seriously compressed Some enterprises adopt mechanical shell breaking equipment, and common extrusion type shell breaking machines and impact type shell breaking machines. The extrusion type shell breaking machine applies pressure to the coffee cherries through the upper extrusion part and the lower extrusion part to realize shell breaking, however, because the coffee cherries have differences in size and shape, the extrusion force is difficult to accurately control, the situation that the coffee beans are damaged due to overlarge pressure and the shell breaking is not thorough due to overlarge pressure is easy to occur. The impact type shell breaking machine breaks the shell of the coffee fruit by utilizing impact force generated by the high-speed rotating part, but the high-speed impact is extremely easy to cause the surface damage and the internal tissue damage of the coffee beans, the flavor substances of the coffee beans are influenced to remain, and the quality of finished products is reduced. Meanwhile, in the process of breaking the shell, as the size and the shape of the coffee cherries are different, the shell breaking force is difficult to accurately control, the coffee beans are easy to damage, the shell breaking effect is uneven, and the difficulty in separating the coffee beans from the coffee shells is increased.
