Product Introduction
APEX Optical Rice Sorter Features
The R series rice color sorter is an entry-level vertical chute sorting machine, specially optimized for full-type rice purification and supporting small & medium-scale rice milling production lines. Different from general grain color sorters with universal multi-grain identification algorithms, this rice-exclusive model is fitted with industrial color CCD cameras that are calibrated according to rice’s unique particle texture, color spectrum and physical characteristics. It maintains steady targeted sorting performance for mainstream rice varieties: white rice, long grain rice, brown rice, parboiled rice, glutinous rice and broken rice. Designed to resolve basic impurity and defective grain sorting troubles in regular rice processing, it acts as a cost-effective fundamental device for routine rice quality improvement.
1. Rice-Tuned CCD Visual Recognition System
Custom optical imaging modules and exclusive recognition algorithms accurately screen out regular rice defects and heterochromatic contaminants, including yellow kernels, black speckled rice, mildewed grains, discolored particles, immature rice and stained rice grains, realizing stable primary purification of raw rice stock.
2. Stable Vertical Gravity Feeding Mechanism
Designed in line with the natural falling property of rice grains, the optimized vertical feeding layout guarantees even material spreading and seamless continuous running. It efficiently avoids material buildup, chute clogging and undetected grains, sustaining stable sorting precision during long-duration mass batch production.
3. Easy Operation & Low Maintenance Cost
Configured with a streamlined intelligent control system and one-click automatic parameter matching function, the equipment needs no professional commissioning work. It greatly cuts daily operation and maintenance expenses, perfectly matching the production demands of rural processing workshops, mini rice mills and individual rice processors.
4. Optional AI Deep Learning Fine Sorting Upgrade
The whole equipment platform reserves an expansion interface for rice-oriented AI deep learning algorithm upgrade. Once the AI function is activated, the system can identify tiny low-contrast subtle defects that pure CCD visual inspection cannot capture, further lifting the purity and commercial grade of final rice products.
With compact overall layout, low energy consumption and durable long-running stability, the standard R series rice color sorter is the preferred entry-level purification equipment for small-volume rice grading and purification tasks. It assists rice processors in unifying rice color uniformity, stripping conventional impurities and effectively raising the economic value of finished rice goods.
Working Principle-How does it work?

Step-by-Step Sorting Workflow:
- Raw mixed rice containing defective grains and impurities is fed into the sealed vertical feeding hopper.
- The precision vibratory feeder evenly disperses rice grains to form stable single-grain vertical free fall along the smooth chute channel.
- High-precision industrial color CCD cameras capture real-time color, texture and surface feature data of each individual rice kernel under uniform stable light sources.
- The built-in dedicated rice sorting processor compares collected imaging data against standard rice color libraries, accurately marking yellow rice, moldy grains, discolored particles and other defective rice impurities.
- High-speed solenoid nozzles eject the identified unqualified defective grains instantly through pulsed compressed air according to the analysis signal.
- Clean qualified rice grains naturally fall into the finished rice collection hopper to complete the whole automatic purification process.
