Vertical Seed Conditioner (VSC)

When preparing seeds for oil extraction, the seed needs to be heated and dried to the correct temperature and moisture. The Crown Vertical Seed Conditioner (VSC) is designed to heat and dry the seed slowly and efficiently, allowing it to be conditioned properly for additional processing.

The seed enters the Crown VSC through the inlet hopper, which provides a surge volume as the seeds flow slowly down through a series of heating sections and air sections. Contact with the tubes provides even and consistent heat transfer to the seed as the patented air system provides moisture removal for additional processing.

The residence time is very important when determining the temperature and moisture removal of the seed. The end user controls the residence time. As the seed rate is increased or decreased, the quantity of heating sections can be changed to control the effective residence time.
