Prevac
Mechanically damaged seed can be separated through a process of PREVAC. The principle of PREVAC is that a liquid (normally water) under pressure enters the cracks in the seed coat of the damaged seed. Seed with cracks will lose the buoyancy, sink and separated from undamaged floating seed.
The BCC PREVAC is generally used in small-scale seed processing plants, R&D facilities or containerized nurseries that process their own seed.
