China Seed Coating Machine Factory

China Seed Coating Machine Manufacturers

Shijiazhuang Xinlu Technology Co., Ltd. is proud to be among the leading China seed coating machine manufacturers, offering a range of precision coating systems that meet the evolving requirements of modern seed treatment operations. Seed coating enhances seed handling, offers protection against pathogens, and supports uniform planting performance by applying a uniform layer of polymers, nutrients, or protective agents to individual seeds.

Advanced Coating Technology
Our seed coating machines employ a rotating drum design combined with airless spray nozzles to ensure even distribution of coating agents. Seeds enter the coating chamber via an adjustable feed auger, where they tumble gently on a perforated drum. Coating liquid is metered through precision flow controls and sprayed onto the moving seed mass. Simultaneously, a warm-air circulation system removes excess moisture, facilitating rapid drying without causing thermal stress to the seed embryo.

Key Design Elements

• Variable Drum Speed: Allows operators to fine-tune the residence time and coating thickness according to seed size and coating formula.

• Modular Spray System: Easily interchangeable nozzles and pump modules support a variety of coating viscosities and chemistries.

• Integrated Drying Zone: A segmented air-heating section provides staged temperature control to prevent clumping and ensure seed integrity.

• Closed-Loop Filtration: Captures overspray and recycles unused coating liquid, minimizing waste and reducing environmental impact.

• User-friendly HMI: Touchscreen controls store recipes for different seed types, simplifying changeovers and reducing setup time.

Operational Benefits
By using Shijiazhuang Xinlu’s coating machines, seed processors achieve consistent application rates (down to ±2 g per 1,000 seeds) and uniform seed appearance. The enhanced flowability of coated seeds reduces blockages in planters and seeders, while the applied film can incorporate fungicides, insecticides, or micronutrients in precisely measured doses. Batch capacities range from 500 kg/h for small-scale research facilities up to 5 t/h for high-volume production lines.

Service and Support
To support our customers, Shijiazhuang Xinlu Technology Co., Ltd. offers on-site commissioning, hands-on training, and preventative-maintenance packages. Detailed operation manuals and spare-parts kits ensure minimal downtime and sustained performance. Our engineering team works closely with each client to configure coating parameters and verify product quality before shipment.
