Coffee is a popular drink around the world, and fine coffee is even more sought after. However, choosing high quality coffee beans is a very important step in making a good cup of coffee. The quality and taste of coffee beans depends on many factors, such as the type of beans, origin, processing method, etc. Among these factors, the quality of coffee beans is the most important. Among these factors, the colour of the coffee beans is a very important indicator. Therefore, coffee factories commonly use coffee bean colour sorter equipment to screen and classify coffee beans. This article will introduce the process principle of coffee bean colour sorter equipment for coffee factories.

The necessity of coffee bean colour sorting

Colour is one of the most important indicators to judge the maturity and quality of coffee beans. Usually, the darker the colour of the coffee beans, the higher the quality. However, if the coffee beans are over-roasted or have quality problems, the colour shade is no longer the only measure of quality. Therefore, it is essential to screen and classify coffee beans by their colour.

Coffee bean colour sorters are used in coffee factories to sort coffee beans by colour and shape. These machines use high-tech technology for screening and sorting of coffee beans to produce high quality screening results.

Process Principle of Coffee Bean Colour Sorters

Coffee bean colour sorter machines use optical sensors to analyse the colour and shape of the coffee beans. As the coffee beans pass through the coffee bean colour sorter machine, light is shone on the coffee beans to pick out and separate those that do not meet the colour and shape criteria.

The optical sensor used in the coffee bean colour sorter machine equipment is a high precision optical detector. It reads the intensity of light and converts it into a digital signal. The coffee bean colour sorter machine will calculate and judge according to different criteria of colour, brightness, shape and size.

There are two types of colour criteria that can be set: brightness and colour difference. For example, a coffee bean colour sorter can sort coffee beans for colour differences to prevent inconsistencies in the colour of the surface of the beans. When performing colour sorting, the coffee bean colour sorter will use at least one of the RGB (Red, Green, Blue) colour models.

Coffee bean shape can be assessed by detecting three-dimensional shapes and surface defects in the beans. These detection results can improve the efficiency and accuracy of coffee bean screening.

Classification of coffee bean colour sorter equipment

Coffee bean colour sorters can be divided into two main categories: traditional type and intelligent type.

Traditional coffee bean colour sorters consist of basic and commonly used sensors, processors and inputs/outputs. They have good reliability and durability, but their performance is limited and cannot adapt to the development of market changes and coffee bean diversity.

Intelligent coffee bean colour sorters are high value-added, high-tech, advanced devices that integrate sensors, circuits, control panels, combination locks, network communications, human-machine interfaces and alarm systems. These features enable the coffee bean colour sorter to intelligently handle a range of complex issues such as detection, screening, counting, separation, sorting and transfer. Intelligent coffee bean colour sorters are also efficient, safe, easy to operate and easy to maintain, making them an essential part of modern coffee processing companies.

Advantages of coffee bean colour sorter application

The application of coffee bean colour sorter equipment brings great advantages, here are a few typical application scenarios:

Improve the quality of coffee beans

Coffee bean colour sorter equipment can help processors improve the quality of coffee beans. Because, with different colours and shapes, the quality, quality and value of coffee beans vary. And the coffee bean colour sorter equipment can quickly, efficiently and accurately judge the colour and shape of coffee beans, which can screen out the high quality coffee beans, thus improving the quality of coffee beans in the whole production line.

Improve processing efficiency

Coffee bean colour sorter equipment can also improve processing efficiency. The traditional screening method requires eye observation and manual screening, which is inefficient and imprecise. The coffee bean colour sorter can quickly screen and sort thousands of coffee beans, improving processing efficiency while ensuring processing quality and consistency.

Reduced operating costs

Coffee bean colour sorter equipment can reduce operating costs. The traditional coffee bean screening method requires a lot of manual involvement, which is very time-consuming and energy-consuming. While the coffee bean colour sorter equipment can automatically complete a large amount of work, reducing the burden of workers, while reducing the wage cost of employees.

Summary

Coffee bean colour sorter equipment plays a vital role in the coffee processing industry, bringing efficient, accurate and automated solutions for screening and sorting coffee beans. This article introduces the process principle, classification, application scenarios and advantages of coffee bean colour sorter equipment, hoping to give readers a deeper understanding of the equipment.
