Dry yeast production in 3 steps :
- Yeasts are removed from fermented mash before distillation. The extraction is carried out by two stages of centrifugal separators with an intermediate washing of the yeast cream.
- Yeasts are thermally deactivated before being concentrated in two falling film evaporators.
- The cream of yeasts is dried to produce a 92-96% concentration, allowing an easy packaging in big-bag.
