The principle of the winnowing machine is gravity segregation based on the aerodynamic and vibration friction. Under the dual role of the wind and amplitude adjustment, the machine can achieve the goal of specific gravity separation. This machine not only can separate the coffee beans, but also can remove the proportion of light impurities such as unripe seeds, bud seeds, bug eat seeds, disease seeds in the wheat, corn, myotonin, paddy and other beans and grains.
LNF-1C shell peeled coffee machine is an efficient combination of coffee processing equipment. The machine is divided into the three processes of milling shell, peeling and separation. It can put coffee skin off in one pass. And the skin is separated with the roll of suction chaff blower. The machine has many virtues such as convenient to operate, stable and reliable performance, less broken beans and clean peeling. It is widely used in small and medium-sized coffee processing plant and specialized households. It is a relatively ideal coffee shell peeled equipment.
