Extending the small type design to larger kernels, our Small Type Maize Seed Coating Machine offers seed companies, cooperatives, and research stations a specialized unit for treating maize seed in limited‑scale settings. This machine balances gentle handling with accurate treatment application for maize kernels weighing up to 1,200 g per liter.
Machine Description
The device consists of a 300 mm diameter horizontal drum mounted at a slight incline (2–4°). A low‑torque gearbox drives the drum at 3–12 rpm, maximizing seed turnover while preventing abrasion. A compact dosing pump delivers treatment solution into a spray manifold located just inside the drum inlet. Treated seed discharges onto a perforated conveyor belt, which passes under an adjustable-temperature heating duct for controlled drying.
Key Features
Kernel‑Friendly Design: Larger drum diameter and slower rotation prevent kernel bruising and maintain germination rates above 95%.
Precise Metering: Pump and manifold achieve ±0.1 mL/kg accuracy, supporting diverse treatment chemistries.
Modular Heating Module: A plug‑in electric heater can be bypassed for ambient drying in heat‑sensitive applications.
Compact Footprint: Occupies under 3 m², making it suitable for pilot plants or demonstration facilities.
Easy‑Clean Surfaces: Food‑grade stainless steel and quick‑release belt slats simplify cleaning between batches.
Performance Data
In validation trials, the small type maize coater achieved uniform coverage on ≥98% of kernel surfaces, with a cycle throughput of 200 kg per 30‑minute batch. Drying times of under 15 minutes are typical when using low‑temperature (≤40 °C) airflow, preserving seed vigor.
After‑Sales Support
