Rice Color Sorter CS-7C (448channels)

Product Overview

Overview of the CS-7C Rice Color Sorter

The rice color sorter is a crucial piece of equipment in the grain processing industry. It can automatically sort particles with different colors based on the optical properties of rice, using photoelectric technology, thereby improving the quality of rice and removing impurities. During operation, rice enters from the top hopper and slides down along the channel through the vibration of the vibrator. In the observation area of the sorting chamber, the system drives the solenoid valve to blow out particles with different colors according to the changes in light intensity and color, while the good products fall into the finished product cavity. It has powerful functions, capable of efficiently removing streaked rice, moldy grains, broken rice, as well as impurities such as glass and plastic. It is not only suitable for sorting various types of rice, but also performs excellently in sorting grains like millet and black rice. Moreover, it can meet the color sorting needs of more than 7,000 types of materials, including beans and medicinal materials. Compared with manual sorting, it saves labor and time, features high efficiency and low cost, and can effectively improve product quality and economic benefits.

The CS-7C is engineered for rice processors who prioritize sorting precision over raw throughput. Its 448-channel configuration and AI deep learning algorithm are fine-tuned for premium-variety rice — including aromatic Thai jasmine, Japanese koshihikari, and organic varieties — where even minor color deviation or shape anomaly can disqualify a batch from premium-grade classification. The CS-7C's shape recognition technology and center-positioning algorithm work in tandem with CCD imaging to achieve an exceptionally low false-rejection rate, preserving valuable grains while reliably eliminating defectives.

Key Features and Technologies

• 448 channels optimized for 4–7 T/H premium and specialty rice varieties

• Shape + color dual recognition — catches cracked, chipped, and undersized grains

• Center-positioning algorithm reduces false positives — protects yield on high-value crops

• Suitable for jasmine rice, koshihikari, organic brown rice, and parboiled long-grain varieties

• Air-efficient solenoid valves reduce compressed air consumption by up to 20% vs. older designs

• 2828×1595×2040 mm footprint — fits compact processing spaces

Who This Machine Is For

The CS-7C is the preferred choice for premium rice brands, organic processors, and export-market suppliers where strict grading tolerances are non-negotiable. If your business sells jasmine, koshihikari, or certified organic rice where a single off-color grain in a retail bag damages your brand reputation, the CS-7C's dual shape-and-color recognition and low false-rejection rate make it the right investment to protect both quality and yield.
