This high efficiency "Spectrum Coffee Huller" can be used for hulling both parchment and dry cherry coffee.
This hulling method is extremely efficient resulting in higher outputs with lower power consumption. The friction between the coffee beans is minimum and therefore there is no loss due to the generation of coffee dust or breakage of beans.
The Huller consists of a Cross Beater which rotates inside a perforated cylinder. The coffee to be hulled is fed into the hulling cylinder where the cross beater forces the coffee to pass through the perforated screen. This results in the complete separation of the husk from the coffee beans. The coffee beans and husk then pass through a powerful Aspirator which can be precisely adjusted for the perfect separation of husk and peels from the coffee beans.
An Oscillating Screen is also provided for the separation of un-hulled coffee from the clean hulled coffee beans by means of specific gravity. The Oscillating screen consists of a conical swinging sieve suspended by a universal joint. The frequency of oscillation can be adjusted by means of a step-less adjustable drive.
