Many seed industry practitioners have troubles when sowing small seeds. Seeds such as carrot, onion, celery, tobacco and medicinal herbs are tiny and irregular in shape. Manual broadcast sowing leads to uneven density, and traditional seeders can hardly achieve one seed per hole. It not only wastes precious seeds, but also causes uneven seedling emergence. A large amount of labor cost is needed for subsequent thinning. The KRT-480D automatic seed pelleting production line is seed processing equipment specially developed for these pain points, providing a mature solution for standardized precision sowing of small seeds.
The KRT-480D automatic seed pelleting production line has a wide range of adaptation. Small and irregular seeds including vegetable seeds like pepper, tomato, carrot, green onion, onion, celery, lettuce, as well as tobacco, forage and various medicinal herb seeds can be pelleted on this equipment. It can be used by seed companies, agricultural research institutes, agricultural universities, large farms, seedling bases and agricultural cooperatives, meeting the pelleting processing demands of entities of different scales.
The complete set of KRT-480D automatic seed pelleting production line is fully equipped, including a pelleting main machine, automatic feeding elevator, pulse dust collector and air pump. It adopts an integrated design with high integration. The machine body is made by integrated carbon steel sheet metal forming technology, equipped with mature centrifugal pelleting technology. The gap between the centrifugal disc and barrel wall can be adjusted from 0.1 mm to 0.15 mm, and the centrifugal rotation speed is adjustable in a wide range of 0–2800 r/min. Process parameters can be flexibly adjusted according to the characteristics of different seeds. It is not easy to jam or miss seeds when processing fine seeds, ensuring stable and smooth processing.
The KRT-480D automatic seed pelleting production line is equipped with multiple intelligent functional systems and features a high degree of automation. The intelligent control system adopts Siemens automatic control scheme, with built-in formula memory and storage function. Adjusted parameters can be saved, so repeated debugging is not required for repeated production. It is easy to operate and convenient for later maintenance. The liquid supply and atomization system uses medical-grade peristaltic pumps for water supply and layered atomized water adding, with accurately controllable flow rate. The precise powder supply system is equipped with a weighing and metering structure to deliver powder evenly and stably. Together with a stirring motor, it effectively prevents powder caking. The supporting automatic feeding elevator is made of stainless steel with corrosion resistance, and supports screw conveying for cyclic feeding and discharging. The pulse dust removal system works synchronously to reduce dust, keep the working environment clean, lower filter element loss and allow easy disassembly, assembly and maintenance.
The KRT-480D automatic seed pelleting production line has clear usage requirements and adapts to conventional workshop environments. The whole machine uses 380V three-phase power supply, and the total power of the main machine is 8.3 kW. It can be put into production when placed on a hardened and flat indoor site, occupying only 20–30 ㎡. The site height shall be ≥ 2.5 m, door width ≥ 2.2 m, with good ventilation.
Seed pelleting of fine seeds is a trend in the standardized development of modern seed industry. With stable mechanical structure, intelligent control system and reliable processing effect, the KRT-480D seed pelleting production line helps seed enterprises and seedling bases turn hard-to-sow small seeds into easy-to-sow pelleted seeds, reduce sowing labor costs, improve seedling quality, and support large-scale and standardized production of the seed industry.
