K2 Coffee Bean Color Sorter

The OURSORT K2 Coffee Bean Color Sorter is designed for automatic sorting and quality control of coffee beans. It helps coffee processors identify and remove discolored, defective, and unwanted beans, creating a cleaner and more consistent product for further processing or packaging.

With a processing capacity of up to 300 kg/h, the K2 is suitable for coffee processing plants, roasting businesses, coffee producers, and other operations that require reliable and continuous sorting.

The K2 combines optical detection, intelligent image analysis, and precise air-jet ejection technology to identify visible differences between qualified and defective coffee beans.

During operation, coffee beans pass through the detection area in a controlled flow. The system analyzes the color and appearance of each bean and activates the corresponding air valve when an unwanted material is detected.

With its compact design and 0.4 kW power consumption, the K2 provides a practical solution for businesses looking to introduce automated quality control without requiring a large production footprint.

Coffee beans are fed into the hopper and evenly distributed into the sorting channel. The optical detection system continuously scans the passing beans and identifies differences in color and visible appearance.

When defective beans or unwanted materials are detected, the intelligent control system activates the corresponding air-jet valve to remove them from the qualified product stream.

Working Process:

Feeding → Even Distribution → Optical Detection → Intelligent Analysis → Air-Jet Ejection → Qualified Coffee Beans

The sorting parameters can be adjusted according to the coffee variety, raw material condition, and customer's quality requirements.

The K2 can be used at different stages of coffee processing, depending on the production process, including green coffee bean processing, roasted coffee sorting, and final quality inspection.

The K2 is suitable for a variety of coffee processing applications:

Green coffee bean sorting

Roasted coffee bean sorting

Coffee processing plants

Coffee roasting factories

Specialty coffee producers

Coffee cooperatives and collection centers

Small and medium-sized coffee businesses

Quality inspection before packaging

For processors handling different coffee varieties, the sorting parameters can be adjusted according to the characteristics of the material.

The machine can also be evaluated for other seeds or granular agricultural products with similar physical characteristics.

The K2 is designed to separate coffee beans according to visible color and appearance differences.

Qualified Coffee Beans

Normally colored beans that meet the customer's quality requirements remain in the finished product.

Discolored Beans

Beans with abnormal or inconsistent colors can be detected and removed.

Defective Beans

Coffee beans with visible appearance defects can be separated from the qualified product.

Foreign Materials

Small stones, stems, dust, and other visually distinguishable unwanted materials can also be removed when suitable for optical sorting.

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

For coffee businesses, sorting is not only about removing defective beans. It is also an important part of maintaining batch consistency and product quality.

The K2 can help processors:

Reduce repetitive manual sorting work

Improve consistency between production batches

Remove visually defective coffee beans

Improve the cleanliness and appearance of finished products

Support continuous processing

Reduce space and energy requirements

Establish a more standardized quality-control process

For coffee roasters and processors, more consistent raw materials can also make subsequent roasting and packaging processes easier to manage.

Build a More Consistent Coffee Processing Process

From green coffee beans to roasted coffee, quality control plays an important role throughout the production process.

The OURSORT K2 Coffee Bean Color Sorter provides an automated sorting solution that combines precision detection with continuous operation. It is designed to help coffee processors reduce manual inspection, improve product consistency, and build a more efficient processing workflow.
