Color sorter price

Color sorters, as the name suggests, enable the sorting of items on a production line by color. A lot of color sorting machines nowadays use high-resolution optical sensors to identify items and expel unwanted impurities from the main line. Since the first use of color sorters decades ago, the sophistication of color sorting machines has been improved significantly with the use of technological innovations, which have enabled more accurate and efficient color sorting in production lines, saving time, labor, and money.

Color sorter applications

In the food industry, grain color sorters and rice color sorter machines are commonly used in agricultural products. The technology used in rice color sorters is according to the color differences of rice materials and uses a high-resolution CCD optical sensor to separate stones and unwanted items. Apart from grain color sorter machines, there are also tea color sorters and plastic color sorters. Color sorter machines are also used in the diamond industry. According to the transparency of diamonds, the color sorter can measure their purity and sort them accordingly. In the mining sorting industry, optical color sorters combine X-ray sorting technology and near-infrared spectrometry to pick out the impurities of ore, minerals, stone, and sand.

Types of color sorters

Color sorters can mainly be divided into chute-type or belt-type color sorters. Chute color sorting machinery is common in the food industry due to its lower costs and higher capacities. The design of a chute color sorter means that optical sensors installed on each side of the chute can be used simultaneously to detect impurities on both sides of a product. But one downside of chute color sorters is that individual items can be damaged on passage through the chute. Belt-type color sorter machines break less material, which is important for nuts, and the product stays relatively static in the transport process since it moves horizontally on the belt. The belt structure makes the transmission smooth and stable without breaking the material.
