Coffee beans can vary in color, size, shape and surface condition during harvesting and processing. Defective beans, immature beans, black beans, broken beans, insect-damaged beans and foreign materials can affect the quality and appearance of the final coffee product.
The OURSORT Coffee Bean Sorting Machine is designed to remove visibly defective coffee beans and foreign materials through optical sorting, helping coffee processors improve product consistency and reduce manual sorting work.
Coffee Bean Sorting Machine from OURSORT
The OURSORT coffee bean sorter is suitable for green coffee beans, roasted coffee beans and different coffee processing applications.
During operation, coffee beans are evenly fed into the sorting machine. The optical system detects differences in color and appearance as the beans pass through the sorting area. Defective beans are separated from qualified beans by high-speed air jets.
The machine operates continuously and can be used as part of a coffee cleaning and processing line.
What Can OURSORT Coffee Bean Sort?
Depending on the raw material and sorting requirements, the machine can help remove:
Black coffee beans
Discolored and abnormal-color beans
Immature or pale beans
Broken and damaged beans
Insect-damaged beans
Visibly defective or mold-affected beans
Stones and other foreign materials
Other coffee beans with obvious color differences
The actual sorting result depends on the characteristics of the coffee beans and the differences between good and defective materials.
Suitable Coffee Bean Applications
Green Coffee Beans
Green coffee beans may contain immature, black, damaged or discolored beans. The sorter can be used after cleaning and screening to remove defective beans before roasting.
Roasted Coffee Beans
After roasting, coffee beans can have different degrees of color caused by roasting conditions. Over-roasted, burnt or abnormal-color beans can be separated when there is a clear visual difference.
Specialty Coffee
For specialty coffee processing, consistent bean quality and appearance are important. Optical sorting can help remove defective beans and improve the uniformity of the finished product.
Where Can the Sorter Be Used?
The machine can be installed at different stages according to the customer's production process.
A typical coffee processing line may include:
Cleaning → Destoning → Screening → Color Sorting → Roasting → Cooling → Packaging
For green coffee, sorting is commonly considered before roasting. For roasted coffee, the sorter can be used after roasting and cooling to remove abnormal-color beans.
The actual position depends on the customer's material, production capacity and sorting requirements.
Is Optical Sorting Suitable for Your Coffee Beans?
Optical sorting works well when defective beans have visible differences in color or appearance.
For example, black, pale, burnt and severely discolored beans can be identified when there is a clear contrast with qualified beans. Defects that cannot be distinguished from the outside may require other inspection or processing methods.
The sorting solution should therefore be selected according to the actual coffee bean sample rather than standard specifications alone.
Material Testing by OURSORT
Coffee beans from different origins and processing methods can have different sizes, colors and defect characteristics. OURSORT provides material testing to help customers evaluate the suitability of optical sorting.
Customers can send coffee bean samples to our factory. Our team can test the material and check the sorting effect for the customer's target defects.
The test can help determine the suitable machine configuration and sorting settings before equipment selection.
