During operation, coffee beans are evenly fed into the machine and pass through the optical detection area in a controlled material flow.

The sorting system analyzes the visible color and appearance of individual beans. When a defective or unwanted bean is detected, the corresponding air valve responds quickly and removes it from the qualified product flow.

Working Process

Feeding → Material Separation → Optical Detection → Intelligent Analysis → Air-Jet Ejection → Qualified Coffee Beans

The sorting parameters can be adjusted according to different coffee varieties, processing conditions, and quality requirements.

The K1 can be used after processes such as drying, hulling, cleaning, roasting, or grading, depending on the customer's production process and sorting objective.

The K1 is suitable for a wide range of coffee processing applications, including:

Green coffee bean sorting

Roasted coffee bean sorting

Specialty coffee processing

Coffee roasting plants

Coffee processing factories

Small and medium-sized coffee producers

Coffee cooperatives and collection centers

Final quality inspection before packaging

It can help coffee businesses remove visually defective beans and improve the consistency of coffee batches before further processing or packaging.

For specialty coffee producers, the K1 can also be used as an additional quality-control step to help maintain a more consistent appearance of the finished beans.

The K1 is designed to separate coffee beans according to visible differences in color and appearance.

Typical sorting targets include:

Good Coffee Beans

Normally colored and visually acceptable coffee beans are retained as the qualified product.

Discolored Beans

Beans with abnormal or inconsistent color can be identified and separated according to the customer's sorting requirements.

Defective Beans

Visually defective beans, including beans with obvious appearance differences, can be removed from the qualified product flow.

Foreign Materials

Unwanted materials that can be visually distinguished from coffee beans may also be separated.

The actual sorting performance depends on the coffee variety, bean size, moisture, surface condition, defect characteristics, and customer requirements. Sample testing is recommended before final machine selection.

The OURSORT K1 Coffee Bean Color Sorter provides a compact and practical solution for coffee businesses that want to improve product consistency and reduce dependence on manual sorting.

With 200 kg/h capacity, ≥99% sorting accuracy, compact dimensions, and low power consumption, the K1 is particularly suitable for small and medium-sized coffee processing operations.

From green coffee beans to roasted coffee beans, the K1 can become an important quality-control step in the production process, helping processors remove unwanted and visually defective beans before the next stage.
