For small nurseries, family farms and seed laboratories, sowing tiny seeds has long been a tough challenge. Seeds such as celery, tobacco, carrot and lettuce are minute and irregularly shaped. Manual sowing can hardly achieve one seed per cell, which wastes plenty of seeds. Extra labor is also required for thinning seedlings afterwards, pushing up the overall nursery cost.
Traditional pelleting machines are expensive, large in footprint and have high operation barriers, making them unaffordable for small and medium seed processing projects. Many farmers and seed labs are searching for compact, stable and easy-to-maintain seed pelleting equipment with reliable pellet quality. Developed specifically for such demands, the KRT-330 seed pelleting machine balances processing precision and operating cost, ideal for small & medium batch seed pelleting.
The frame and centrifugal disc assembly of KRT-330 are fully made of stainless steel. The cabinet is 1.5mm thick, heat and corrosion resistant for longer service life. Compact in structure, it occupies little workshop space. One single operator can finish the whole workflow, perfectly suited for laboratories and family growers.
It processes 300–500g raw seeds per batch. Processing parameters can be flexibly adjusted according to seed varieties and pellet multiplication factors. The complete system includes the main pelleting host, two temperature-controlled drying barrels, a dust collector and an air pump, to finish seed pelleting, drying and dust collection in one integrated workflow.
Five core systems guarantee stable pellet quality for KRT-330:
- Centrifugal System: Equipped with a 1.5kW main spindle motor and Delta frequency converter, plus thickened 304 stainless steel centrifugal disc. Rotation speed ranges from 50 to 2800 rpm. Adjustable centrifugal speed fits various fine seeds like tobacco, celery and pepper.
- Liquid Supply System: Medical-grade peristaltic pump delivers liquid with continuously adjustable flow, ensuring even coating of liquid on seed surfaces.
- Powder Feeding System: Vertical screw feeding with electronic weight monitoring to track powder dosage in real time for accurate and stable powder supply. The powder hopper holds up to 4kg of pelleting powder.
- Drying System: Electric heating suspension drying with controllable temperature from ambient temperature to 40℃ for fast drying.
- Dust Collection System: Industrial vacuum cleaner for continuous dust removal with 1–6 adjustable power levels, keeping a clean working environment and lowering dust pollution.
KRT-330 delivers consistent pellet quality, with 99% pellet qualification rate, 99% single-seed rate and 99% uniformity. Smooth and well-shaped pellets enable easy one-seed-per-cell sowing in plug trays, greatly cutting seed-thinning labor and saving seeds.
Low investment, small footprint, simple operation and easy maintenance. Compatible with multiple seed types, it handles trial orders and small-batch production flexibly.
