Minimizing defects in green and roasted coffee is crucial for specialty coffee roasters. This is because the Specialty Coffee Association’s green coffee standards state that defective coffee is by its nature not specialty.
For a coffee to even be considered specialty grade, the green must have zero primary defects and five or [fewer] secondary defects per 350 grams,Defects such as quakers and scorched or tipped beans can negatively affect the overall flavor experience.
While you can manually sort coffee beans, color sorter machines are both more consistent and quicker. This means they streamline roastery operations – which is more important than ever against a backdrop of rising coffee prices.
Our best-in-class technology sorts and grades green and roasted coffee beans with unrivaled accuracy. As well as removing foreign materials, our coffee bean sorters eject imperfect beans while minimizing waste of those that are good - so you can maximize yields, prevent recalls, and keep customers happy.

Coffee Bean Color Sorter is a machine that uses cameras and sensors to detect the color of coffee beans. The coffee beans are then sorted according to their color.
This is done by using a combination of light sources, optical filters, and image processing algorithms.
The light source illuminates the coffee beans and the optical filter allows only certain wavelengths of light to pass through.
This filtered light is then detected by an array of cameras which capture images of the coffee beans.
These images are then processed by an algorithm which determines the color of the coffee beans and sorts it accordingly.
1. Removing foreign materials and protecting equipment
Our coffee bean sorters eject foreign materials such as sticks and stones, extending the grinder lifespan and protect other downstream equipment.
2. Sorting green and roasted beans
WESORT's coffee bean sorting machines detect and eject beans with discoloration, mold, and insect bites, as well as unripened Quakers that won't brown. Arabica and Robusta
3. Arabica and Robusta
WESORT's machines sort accurately and maximize yields whether the beans are Arabica or the less homogeneous Robusta species.
4. Dependable in tough conditions
Our coffee bean sorters perform well, minimizing false rejects and rework, and maximizing yields, even in very dusty environments.
Do you want to improve the coffee quality by coffee bean sorting machine?
Don’t miss using this high-tech intelligent coffee bean sorting machine to improve the quality of your coffee beans, achieve perfect quality control with less effort, and ultra-high consistency.
Our industry-leading technologies in optical sorting achieve extremely low false reject rates, reducing rework, and optimizing yields.
At WEOSRT, we’ve been designing color sorter to support global specialty coffee since 2014.
WESORT coffee bean color sorter can provide models with different production capacities for small, medium and even large roasters and processing plants. After loading beans into the color sorter machine, roasters can easily navigate its user-friendly interface and smart operation features.
