Color sorter can sorting a variety of grain. For example, brown rice, rice, wheat, oats, millet, etc.

We provide different solutions for different roles

Cleans and removes impurities, and divides grains into different grades. And it has a small color sorter for farms or individuals. When the system removes ergot, it can help you increase the wheat grade from feed to first. The sorter can remove wheat from barley, barley from rape, and ergot from wheat.

Grain Sorting

High-performance grain color sorter

Grain sorting plays a key role for the farm. The most important thing about grain sorting is accurate positioning. Line-scan Charge Coupled Device (CCD) is widely used in color sorting systems, and its processing algorithm is very complicated. Use multiple different wavelengths of visible light to detect extremely subtle color differences and greatly improve product quality.

Line scan sensors can be used well for imaging high-speed objects or webs, and they can work well for lighting at low speeds. With a single line of pixels, the line scan sensor establishes a continuous image resolution that is not limited to the vertical direction. For these reasons, line scan sensors are suitable for demanding real-time performance of machine vision systems.

The working process of the grain color sorter

1. The processed grains are automatically fed into the input hopper.

2. The grain is sent to the gravity chute through the feed vibrator. The surface of the chute is smooth enough to reduce the friction between the grain and the chute.

3. After the grain passes through the chute, it enters the optical inspection area. Here, the Line-scan Charge Coupled Device (CCD) will play its role. Here, the grain will be sorted, which is also the most important step.

4. The grains are sorted into different channels after sorting, and finally fall from the outlets of different channels, and the sorting is completed.

Why grain color sorter?

When the factory receives grains from farmers, if the grains contain impurities or dry grains, the quality and price of the overall grains will be lowered for the farmers. For factories, it takes more time and cost for grains to come out with excessive impurities. And in the subsequent processing process, foreign matter, such as sand, dust, sticks, string, rocks, part of the bag, etc., will inevitably be mixed. If some grains are mildewed, it will cause more grains to be contaminated and cause serious losses.


Therefore, these foreign objects must be removed from the grains before further grinding and processing. Especially grains harvested by machines such as wheat also contain seeds of other weeds. When these grains are finally processed into the market, the white rice is mixed with other small black seeds, and the wheat flour is not so pure. It is absolutely impossible for such a product to be first-class. In addition, these grains always contain damaged, such as peanuts, beans, customers will not always choose those options that contain broken grains when buying.

Therefore, the use of color sorters is necessary. It can be used from the initial grain sorting to the sorting of the processing process, which not only saves labour costs, but also improves product quality, increases income, and obtains more orders and trust. Almost all modern cereals today

Processing plants are using optical sorting technology to produce high-quality grains.
