GREEN COFFEE CLEANER / CRIPER SYSTEM ( Latest economic combined version )
Cleaner: sturdy and reliable machine, of limited dimensions and easy to place, it bases its operation on the difference of specific weight of different products, crossed by a flow of air properly dosed and directed.
Thus are separated: coffee, heavy bodies and dusty air.
The machine body in painted iron presents on the top the loading mouth of ø 120 mm. that introduces the product into the turbo disperser placed inside.
A suitable device and flow regulation valve contribute to optimize the calibration according to the desired degree of cleanliness. On the side, the suction fan takes the air rich in dust and sends it to more suitable areas. At the bottom, an exhaust outlet continuously sends the treated product to downstream equipment. The machine body is supported and bolted to an iron section truss, painted and normally sized in height to meet the specific needs of the plant.
Sifter: simple machine with limited overall dimensions, it allows the separation of coffee beans of two different grain sizes above and below the sample size. Therefore it also allows to separate broken beans from whole ones. Its operation is based on the constant feeding of coffee to a separating drum, equipped with appropriate holes and provided with suitable handling paddles, such as to allow the advancement and the passage or not of coffee.
The machine body, made of iron profiles and closed by bolted and painted panels, presents on one side the coffee loading mouth that directly enters the sieve placed inside. The height of the support feet is adjustable. Underneath there is a large hopper for the collection of minimum caliber beans. On the opposite side of the feeding there is the hopper for the unloading of the grains of superior caliber. The regulation of the hourly production and of the consequent separation capacity is given by the motion of this drum which is controlled by a strong variator motion equipped with adjustment through a knob (speed ratio 1:4).
Possibility of rapid insertion of other sieves of different calibre (optional).
Practically no maintenance.
