Coffee Beans Processing Machine

Introduction

Coffee Beans processing machine is used to clean the coffee beans. The process technology of coffee beans cleaning is integrated with sifting, de-stoning, magnetic separation, and other kinds of cleaning methods. This is the most advanced technology that can clean coffee beans thoroughly to get the pure coffee beans.

The coffee beans processing machine is mainly composed of the following machines:

Air screen cleaner: to remove the dust, leaf, light impurity, and then remove large, small impurity and small particles according to the difference in weight and density between the coffee beans and the impurities.

De-stoner: remove stones left in the material

Gravity separator: blighted seed, budding seed, damaged seed (by insect), rotten seed, deteriorated seed, moldy seed, non-viable seed, etc.

Magnetic machine: remove the iron impurities from the material.

Color Sorter: separate and remove seeds with different color to raise the quality of the coffee beans

Grading machine:  separate the beans to different size

Packing machine: automatic packing machine to save manpower

How Our Coffee Beans Cleaning Line Works:

For washed coffee beans, no need in hulling 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 de-stoner. Big and small size impurity will be sorted out from the vibration separator. The stones will be sorted out through the de-stoner. The working principle is utilizing the gravity difference of the material.

To reach export standard, grading is needed (with sieves inside) according to the size of the coffee beans. 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. Some buyers may add a belt conveyor for final manual checking. The last step is weighing and packing.
