China Corn Seed Processing Line

China Corn Seed Processing Line

Shijiazhuang Xinlu Technology Co., Ltd. introduces its China Corn Seed Processing Line, a comprehensive solution engineered to transform raw maize harvests into uniformly cleaned, graded, and condition‑ready seed lots suitable for planting or further treatment. This turnkey line combines multiple sequential modules—each optimized for reliability and ease of operation—into a continuous automated workflow.

Process Overview

1. Bulk Reception & Metering

• Corn seed is delivered via a hopper fitted with level sensors and a variable‑speed feeder that ensures a consistent and gentle flow into the cleaning modules.

2. Pre‑Cleaning Module

• A two‑deck vibrating screener removes large debris—cobs, stalk fragments, and clods—while an integrated aspirator draws off fines, dust, and lightweight foreign matter.

3. Magnetic & De‑Stoning Section

• A magnetic drum separator extracts ferrous particles. A precision de‑stoner then separates stones and earth clods through calibrated airflow and deck oscillation, protecting downstream equipment.

4. Size Grading

• Multi‑deck sieving units classify kernels into large, medium, and small fractions. Quick‑change frames allow mesh sizes to be swapped rapidly, accommodating different corn hybrids and certification requirements.

5. Density Separation

• Gravity separators stratify kernels by bulk density. Adjustable deck angle, stroke amplitude, and airflow rate enable removal of shriveled or immature seeds, yielding a high‑uniformity product.

6. Conditioning & Buffering

• Cleaned and graded seed is conveyed to buffer bins, where moisture sensors and optional dryers ensure seed moisture aligns with storage or treatment specifications.

Key Features

• Modular Construction: Each processing stage functions independently, enabling capacity expansion from 5 t/h up to 50 t/h without major layout changes.

• Centralized PLC Control: Touchscreen interface stores recipes for different corn varieties, simplifying changeovers and ensuring process repeatability.

• Food‑Grade Contact Surfaces: All seed‑touched components are crafted from stainless steel or FDA‑approved polymers to maintain hygiene standards.

• Energy‑Efficient Drives: Variable‑frequency motors on conveyors, fans, and screens optimize energy consumption by matching output to real‑time load.

• Enclosed Dust Collection: Integrated cyclonic separators and dust hoods minimize airborne particulates, ensuring a clean working environment.
