Many raw seeds of vegetables, medicinal herbs and tobacco are tiny and irregular in shape. Direct sowing often leads to empty holes, multiple seeds per hole and uneven seeding. It not only costs plenty of manual labor, but also makes it hard to guarantee uniform seedling emergence. Seed pelletization is a process of coating fine seeds evenly with pellet powder. It turns seeds into round, uniform pellets that match precision sowing machines.
Developed by Hebei Kairuot, the 2RD-600 seed pellet machine is built for seed companies, agricultural research institutes, agricultural universities, large farms and seedling bases. It delivers stable and efficient seed pelletizing processing.
The 2RD-600 seed pellet machine processes 300–6000 grams of raw seeds per batch. One processing cycle takes 30–40 minutes. It achieves a finished product rate of 99%, single-seed rate of 99% and uniformity of 99%. Pelleted seeds have consistent sizes, ideal for follow-up automatic precision sowing. It greatly improves sowing accuracy for seedling raising, cuts seed waste and ensures even seedling emergence.
The 2RD-600 seed pellet machine adopts centrifugal granulation technology. Its core centrifugal disc is made of thickened 304 stainless steel, corrosion-resistant and long-lasting. The gap between the centrifugal disc and drum wall is only 0.1~0.15 mm. It avoids seed jamming and leakage even for ultra-fine seeds such as tobacco seeds. The centrifugal speed is adjustable from 50 to 1400 r/min. Operators can set parameters flexibly according to seed types and pellet multiple to meet pelletizing requirements of various crop seeds.
Equipped with Siemens automatic control system, the 2RD-600 seed pellet machine features accurate and stable control with built-in formula memory. Saved formulas for different seeds can be called directly for next batch, eliminating repeated parameter adjustment. It has high automation, easy operation and simple later maintenance.
Its liquid feeding system uses medical-grade peristaltic pump for liquid supply. The atomizing spray speed reaches 2800 r/min with fine and even atomization. Liquid flow is adjustable to realize layered coating. Every seed gets uniform powder coating without uneven thickness. It is fitted with an independent automatic lifting feeding and powder supply system. The vertical screw feeding structure delivers powder with precise metering and stable supply, ensuring consistent pellet forming.
The 2RD-600 seed pellet machine comes with an industrial pulse dust collection system. It removes dust throughout pelletizing to keep the workshop clean, lower dust pollution and improve working conditions.
It works steadily for vegetable seeds including lettuce, carrot and chili, as well as cash crop seeds such as tobacco. It turns hard-to-sow tiny seeds into standard uniform pellets, helping seed industry clients realize standardized and large-scale production.
