Hawit seven chute color sorter

Hawit G Model Rice Color Sorter with 7 Chutes 441 Channels

Model: HWT-GR7 ( 7 Chutes · 441 Channels )

High-Resolution Sorting for Medium-Scale Rice Mills

Purpose‑built for rice processors who need consistent quality at 4–5 tons per hour.

The Hawit HWT-GR7 handles the full spectrum of rice varieties — Basmati, Parboiled, and Raw rice — with a throughput of 4–5 tons per hour (at approximately 5% contamination).

Every machine ships with a Toshiba 5400‑pixel full‑color CCD camera, and customers can specify Hawit, SMC (Japan), or Matrix (Italy) ejectors.

Standard features include photo capture, online capacity calculation, mobile operation, and a high‑resolution sorting engine that delivers an excellent rejection ratio while keeping capacity stable.

Ⅰ. What keeps accuracy above 99.9% on every run

A camera that catches what the naked eye cannot.
The 5400‑pixel Toshiba CCD resolves defects as small as 0.04 mm². Black tips, light‑yellow grains, and subtle chalky spots are captured and acted on the instant they pass through the optical path.

Processing power that matches your line speed.
The ARM+FPGA architecture processes color and shape algorithms in parallel, so the sorter holds accuracy at ≥99.9% even when running at peak feed rates. There is no lag when the machine is asked to do more.

One‑key intelligence that makes changeovers painless.
Operators input the target color, shape, size, and defect tolerance just once. The sorter calculates the optimal scheme independently and applies it across all 441 channels. When switching from Parboiled to Raw rice, the transition is immediate — no manual fine‑tuning required.

Ⅱ. Designed to run cool, clean, and cost‑effective

Lighting that adapts to the grain in front of it.
The LED system uses stepless digital dimming. Brightness self‑calibrates as ambient conditions shift or product characteristics change, so the cameras always receive a clean, consistent image.

A self‑checking routine that removes the guesswork.
Cameras, control boards, and background panels are automatically verified at startup. There is no checklist to work through — the machine tells you it is ready.

Ejectors that prioritize longevity and air savings.
High‑frequency ejectors are rated for billions of cycles, with low air consumption and rapid response. Whether the customer opts for Hawit, SMC, or Matrix, the valve block is factory‑matched to the application.

Independent chute feeding.
Each of the 7 chutes works as a self‑contained sorting lane. Operators can group or isolate channels based on the contamination profile, which helps drive down both the rejection ratio and compressed‑air usage.

Thermal and dust control built into the structure.
An active heat‑dissipation design keeps internal electronics at room temperature, improving the signal‑to‑noise ratio. Precision dust collection maintains a clean optical chamber, preserving image clarity shift after shift.
