Hand Selected Conveyor China

Hand Selected Conveyor China

Efficient manual inspection remains vital for high‑value seed lots where visual defect removal is required. Shijiazhuang Xinlu Technology Co., Ltd.’s Hand Selected Conveyor provides ergonomic, illumination‑optimized conveyors designed specifically for hand‑sorting applications in seed, grain, and specialty crop facilities.

System Configuration
The hand selected conveyor consists of a 2 m long, 400 mm wide flat‐bed belt, driven by a low‑speed motor (5–15 m/min). Overhead, an LED lighting array with adjustable intensity and color temperature illuminates the belt surface, enhancing contrast between healthy kernels and visual defects. An operator stand runs alongside the belt, with height adjustment to maintain ergonomic posture. Rejected seeds are directed into integrated side channels or bins via hand‑operated push bars.

Key Features

• Uniform Illumination: High‑CRI LED panels deliver 5,000–6,500 K light, reducing eye fatigue and improving defect detection.

• Adjustable Feed Rate: Variable‑frequency drive allows precise control of belt speed to match sorting pace.

• Ergonomic Design: Padded standing mats, adjustable handrails, and optional anti‑fatigue stools support operator comfort during long shifts.

• Modular Bins and Diverts: Side channels can be configured for multiple reject categories—broken, discolored, foreign materials—enabling detailed quality grading.

• Compact Footprint: Footprint under 4 m², suitable for small labs or inline integration in larger processing lines.

Operational Advantages

• Manual sorting reduces reliance on optical sorters for subtle defects, such as hairline cracks or discoloration not detected by cameras.

• Flexible design allows rapid reconfiguration for different seed types or grading schemes.

• Illumination system improves operator accuracy by up to 30% in defect recognition tests.

Maintenance and Training
Routine maintenance includes belt replacement, LED panel cleaning, and motor lubrication. Shijiazhuang Xinlu Technology Co., Ltd. provides assembly instructions, operator ergonomics training, and replacement parts kits to keep hand selected conveyors operating effectively.
