Seed coating machine with integrated dryer

Seed coating refers to the covering of seeds with external fluids, biologicals, chemicals, and solutions to protect the seeds, enhance germination and improve immunity. A common challenge for seed coating is that these materials may spill. Thus, in order to optimize the process, it is essential to use a machine that will reduce the workers’exposure.

Boost productivity by automatically coating and drying seeds

Designed by Seed Processing Holland , the RDC’s (800 – 500 and 300) are advanced seed film coaters with an integrated dryer. It simultaneously coats and dries agricultural and vegetable seeds, applying a higher percentage of liquid to allow direct packaging of the seeds once the process is completed. It further uses a high-grade film coating formula and pays special attention to the drying speed, film formation and coverage. To ensure an optimal coating process, the unit controls the seed temperature during the coating process. It also features a special rotating movement that helps achieve an equal and even seed coating.

Moreover, the air humidity and temperature of the airflow created during the coating process are adjustable, enabling operators to regulate and control the entire process. Since it’s a closed system, it’s also suitable for insecticides and fungicides applications.

The RDC 800 boasts a window and lighting in the cover, so you can control the process visually as well. Its modular design further makes it easy to clean, while its nickel-plated coating chamber protects it from excessive wear.

Lastly, the RDC-800 has a capacity between 20 and 52 litres of seed per batch and is ideal for vegetable seeds, grains, and flower seeds. Users can pack the seeds as soon as they are discharged.
