This unit has been designed to produce a uniform quality of first parchment and total pulping of intake fruits. This pulping system comprises of the following features:

• It has an inbuilt feature that ensures that no stones are allowed to enter the pulper. A regulating door ensures that the feed can be varied.

• The primary pulping unit is 2, 3 or 4 disc type. A rigid type chop is fitted to cut down on maintenance. The pulping action takes place between the rubbing action of the bulbs on the disc and the lateral pulping bars on the chop rails. The gap between the surface of the bulb and the chop rail can be adjusted to allow for any clearance that may be required for the individual varieties and sizes of the coffee fruit being processed.

• The pregrader comprises a twin chamber tank with a wet grading progressive sized sieve mounted on an epileptic bearing to ensure the separation of the firsts, seconds, and lights. The firsts fall into the primary chamber and are discharged via a syphon pipe to the fermentation tanks. The pregrader produces a first grade of well pulped and uniform size parchment free from skins which results in making the final washing easier.
