How Our Coffee Bean Cleaning Machinery Works:

For washed coffee beans, no need in dehulling and polishing. If the capacity is large, like 10 tons per hour or even more, we recommend buyers to set up a suitable silo. The first step is cleaning, which usually adopts two machines: vibration separator and destoner. Big and small size impurity will be sorted out from the vibration separator. The stones will be sorted out through the destoner. The working principle is utilizing the gravity difference of the material.

To reach export standard, we need grading (with sieves inside) according to the beans’ size. Usually we classify them into 4 grades. The best beans will come from the middle 2 layers, then will be processed in the gravity separator. This high quality machine will sort out the shriveled or insect bitten kernels. Then, different color beans will be rejected in this color sorter machine. Next, some buyers add the manual checking belt. The last step is weighing and packing.

For dry coffee beans, besides of what listed above, we add dehuller and polishing machine, which will form another complete processing plant.
