High-quality development of the seed industry relies on upgraded seed pretreatment technologies. For tiny, irregular seeds such as tobacco and lettuce, direct sowing of raw seeds is difficult and seeding rates are hard to control. Seed pelletizing serves as the core solution to this pain point. The fully automatic KRT-480 seed pelletizing production line adopts centrifugal pelletizing technology, delivering stable and reliable seed pellet processing solutions for seed enterprises, research institutes and large planting bases.
The main frame and core centrifugal disc assembly of the KRT-480 seed pelletizer are built with thickened 304 stainless steel, offering great corrosion resistance and rust-proof performance for long-term continuous stable operation. The clearance between the centrifugal disc and drum wall is precisely controlled at only 0.1–0.15 mm. When processing extra-small seeds like tobacco seeds, it effectively prevents seed jamming, leakage and dropping. The centrifugal speed is adjustable to match different seed types and pellet multiplication requirements.
Equipped with a Siemens automatic control system, the KRT-480 seed pelletizer supports recipe memory and storage. You may preset and save processing parameters for various crop seeds. No repeated ratio adjustment is needed when switching seed varieties, lowering manual operation barriers. Featuring stable and accurate control logic, the machine is easy for new operators to master and simple to maintain.
The KRT-480 seed pelletizer consists of separate modules for liquid supply, powder feeding and dust collection, which work in coordination to complete pellet processing. The liquid supply system uses a medical-grade peristaltic pump for even atomization and adjustable liquid output. The powder feeding system adopts a gravimetric metering feeding structure with a horizontal screw for uniform powder delivery. A supporting industrial pulse dust collector captures dust throughout processing to keep the workshop clean and improve working conditions.
The KRT-480 operates on the centrifugal pelletizing principle. Seeds stay suspended and rolling inside the drum, while pellet powder and chemicals coat the seed surface evenly layer by layer. It uses a belt drive structure that delivers higher torque and stronger power for larger throughput per unit time.
The KRT-480 seed pelletizer fits a wide range of applications: seed companies, agricultural academies, research labs of agricultural universities, large-scale farms, seedling nurseries and agricultural cooperatives. Its batch capacity is flexible: raw seed loading ranges from 300 g to 3000 g per batch, with a processing cycle of 30–40 minutes. It meets both lab trial and mass production demands. Finished pellets feature stable pass rate, single-seed rate and uniformity. The processed pellet seeds are round and neat. When matched with precision seeders, they easily achieve one seed per hole, greatly cutting seed and labor costs.
From fine tobacco seeds to various vegetable seeds, the KRT-480 seed pelletizer turns irregular raw seeds into standard pellet seeds with consistent automated processes. It completes the refined seed treatment workflow, enables precision sowing and reduces costs while boosting efficiency.
