Abstract

To address the challenges of low automation, insufficient precision in seed-powder-liquid ratio control, and suboptimal coating quality in current domestic small-sized forage grass seed pelletization coating equipment, this study designed and developed a fully automated pelletization coating system. The system employs a microcontroller unit (MCU) as the core controller, integrates an ATFC101 serial touchscreen for human-machine interaction, and combines programming and electronic control technologies to achieve precise regulation of material and liquid supply, enabling fully automated and quantized coating operations. The hardware of the feeding system adopts a bidirectional thyristor (Triac) circuit, while the software implements a dual-mode control strategy to ensure high precision and stable material delivery. Experimental trials using Caragana seeds and pelletization powder demonstrated that the integrated electro-control system achieved full automation, with seed dispensing deviation controlled within 1.2 g and powder deviation within 0.32 g, significantly improving dosing accuracy. This research provides critical theoretical and technical insights for optimizing automated pelletization coating equipment for small-sized forage grass seeds.
