Wheat Seed Coating Machine

Wheat Seed Coating Machine

Ensuring uniform application of protective treatments is critical to the performance of wheat seed in both planting and storage. Shijiazhuang Xinlu Technology Co., Ltd.’s Wheat Seed Coating Machine delivers precise, reproducible coatings—whether fungicidal, nutritional, or coloring agents—across varied seed volumes, supporting both small‑scale and industrial operations.

Design and Operation
Wheat seed enters a rotating coating drum outfitted with adjustable internal baffles. A metered pump system delivers liquid treatment agents into a spray manifold positioned at the drum inlet. As the drum rotates at a controlled speed (5–20 rpm), seeds tumble gently, and the spray nozzles ensure even distribution of the coating liquid. The drum tilt angle (0–5°) and rotational speed can be customized to manage dwell time and coverage. After coating, seed exits onto a perforated belt where warm air (30–50 °C) dries the applied film, ensuring adhesion without compromising seed viability.

Key Features

• Precision Dosing Pumps: Peristaltic or diaphragm pumps dispense treatment volumes from 0.2% to 3% weight‑by‑weight with ±0.05% accuracy.

• Variable‑Speed Drum: Electric motor with VFD control enables rapid adjustment of rotation speed to suit different seed sizes and coating viscosities.

• Modular Spray Manifold: Removable nozzle assemblies simplify cleaning and maintenance, while interchangeable nozzle types support a range of viscosities.

• Integrated Drying Conveyor: A multi‑zone heated belt with adjustable airflow and temperature ensures thorough drying in a compact footprint.

• Enclosed System: Dust‑tight housing and filtered vents reduce operator exposure to treatment agents and maintain environmental safety.

Performance Metrics
Laboratory and on‑site tests demonstrate uniform coating thickness across 99% of the seed surface area, with germination rates consistently above 95% post‑treatment. Typical capacities range from 1 t/h in pilot units to 10 t/h in industrial configurations. The drying conveyor’s temperature zones can be programmed to ramp gradually, preserving seed vigor while achieving a dry, non‑tacky finish.
