Hawit S-Model Rice Color Sorter With 8 Chutes 504 Channels

8 Chutes · 504 Channels · Model HWT-GR8

High-Volume Precision for the Demanding Mill

A high-capacity sorter that does not sacrifice finesse for throughput.
The Hawit HWT-GR8 is an 8-chute rice color sorter engineered for mills that need serious sorting muscle — 5 to 6 tons per hour under typical contamination levels of 3%–5%.

It handles all major rice varieties, including Basmati, Parboiled, and Raw rice, while bringing a refined optical system to bear on a notoriously difficult contaminant: glass.

With a specialized 350mm glass sorting distance and dedicated detection algorithms, the GR8 identifies and removes glass shards that pose a genuine food safety hazard.

The machine is built around a Toshiba 5400-pixel full-color CCD camera, and customers can configure the ejector system to their preference — Hawit, SMC from Japan, or Matrix from Italy.

A spacious 15-inch true-color touchscreen anchors the user interface, while photo capture, shape sorting, reverse sorting, and remote operation capability from the factory in China round out the standard feature set.

1. The systems behind sustained high accuracy

Imaging that sets a high bar.
At the center of the GR8 is a Toshiba 5400-pixel full-color CCD camera. It scans grain at 16,000 times per second, picking out defects as small as 0.01 mm². The RGB tri-chromatic acquisition system renders colors with such precision that even subtle off-color grains — a faintly yellow kernel or a tiny black speck — are captured and acted upon immediately.

Processing that handles the load.
The DSP+FPGA architecture processes color and shape algorithms in parallel, delivering genuine “color selection + shape selection” in one pass. Through the one-key intelligent operation system, operators define what constitutes a reject, and the machine automatically deploys the optimal sorting scheme across all 504 channels. Multiple sorting modes can be saved and recalled as production needs change.

Lighting that adapts without intervention.
A unique cold shadowless LED source illuminates the sorting path evenly and efficiently. Advanced digital stepless dimming allows the system to automatically adjust brightness in response to material characteristics and environmental shifts. This keeps the image signal clean and consistent without requiring constant manual tuning.

Designed to stay clean and cool.
Precision dust collection is built into the sorting chamber, actively clearing the optical path of debris. This preserves high identification accuracy from the first batch to the last. An efficient heat dissipation system maintains all internal electronics at room temperature, improving the signal-to-noise ratio and extending the machine's overall service life.

Ejectors that perform under pressure.
High-frequency ejectors are rated for 5 to 10 billion cycles and operate with minimal air consumption. Their rapid response and precise timing deliver an impressive 50:1 rejection ratio, ensuring that good product stays where it belongs. The mechanical structure and tri-chromatic control system work together to guarantee 99.999% accuracy at every ejection point.

Model: HWT-SR4For the Small Mill That Refuses to Compromise You do not need a massive production line to demand top-tier sorting. The Hawit S4 is a compact, entry-level rice sorter that brings the same core technology found in our largest machines into a footprint that fits smaller mills and start-up operations. Designed to handle Basmati, Parboiled, and Raw rice at around 2 tons per hour, it proves that small capacity does not have to mean basic performance. What truly sets this model apart is its ability to tackle a problem that plagues many small mills: glass contamination. With a specialized 350mm glass sorting distance and dedicated algorithms, it identifies and removes glass fragments that ordinary sorters miss, protecting your brand and your customers. Add to that standard features like photo capture, shape sorting, reverse sorting, and remote operation — all managed through a crisp 15-inch display — and you have a machine that punches well above its weight.
