Sorting and cleaning

An efficient cleaning system guarantees a constant quality level as well as giving an added value to the product. It can be made possible by eliminating the defects and impurities that could compromise the taste and the aroma of this special drink.
In common  green coffee bought from the market,  there may be several defects and impurities:
ferrous bodies, residues of soil, dust, stones, sticks, scraps, immature and defective beans and other foreign bodies.
These can be separated from the coffee using specific tools such as:
vibrating sieves combined with suction
densimetric tables/ gravity table machines
opto-electronic colour sorting machines
centralized filters for dust collecting

A cleaning plant is therefore an effective guarantee of a high quality of production and helps to preserve the integrity of the machinery in the next processing steps.
