In the coffee making process, the quality of coffee beans is a very critical factor. The intervention of modern industrial technology allows the coffee industry to maintain stable quality during the raw material selection stage. Using a color sorter is a common method for identifying and sorting different types of coffee beans. These machines use optical sensors and computer vision technology to quickly and accurately distinguish the color and appearance characteristics of coffee beans. The color sorter can function in the following two stages.

First， Removing impurities from coffee bean raw materials

In the first stage of coffee beans, a color sorter can be used to pick out foreign materials adulterated in the coffee beans. Removing foreign materials and protecting equipment, Our coffee bean sorters eject foreign materials such as sticks and stones, extending the grinder lifespan and protecting other downstream equipment.

You can also filter Sorting green and roasted beans

GroTech’s coffee bean sorting machines detect and eject beans with discoloration, mold, and insect bites, as well as unripened ones that won’t brown.

Second， Color sorting roasted coffee beans

Coffee beans in different roasting states have different colors, but during the roasting process, some dark roasted and light roasted coffee beans may be mixed. At this time, we can use a color sorter to select different types of coffee. beans. GroTech's machines sort accurately and maximize yields whether the beans are Arabica or the less homogeneous Robusta species. Or coffee beans from Yunnan, China.

Third， How to use the coffee color sorter

1. Adjust the parameters of the color sorter: Adjust the parameters of the color sorter according to the characteristics of the coffee beans and the required screening criteria. Relevant parameters have been preset in the system, and users can make customized fine-tuning according to their own needs.

2. Identify and classify coffee beans: The color sorter will identify and classify coffee beans based on preset parameters and standards. It can detect differences in color, size, and cosmetic defects.

Fourth，The benefits of using a color sorter to screen coffee beans

1. Improve work efficiency: The color sorter can quickly process a large number of coffee bean samples, which is faster and more accurate than manual screening. It can complete a large number of tasks in a short time and improve work efficiency.

2. Improve quality consistency: The color sorter can evaluate the consistency of coffee beans to ensure that the quality of coffee beans in each batch is similar. This helps maintain product quality stability and consistency.

3. Reduce human errors: Compared with manual screening, color sorters are more accurate and reduce the possibility of human errors. It can automatically screen based on preset parameters to avoid the impact of subjective judgment and individual differences on the screening results.

In general, using a color sorter can improve the screening efficiency of coffee beans and ensure the stability and consistency of product quality. This is very important for the production and processing aspects of the coffee industry.
