Dry yeasts production

Principle

Dry yeast production in 3 steps : 

  1. 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.
  2. Yeasts are thermally deactivated before being concentrated in two falling film evaporators.
  3. The cream of yeasts is dried to produce a 92-96% concentration, allowing an easy packaging in big-bag.
Specifications
  • Recovery of the dry yeasts for alcohol units of 600hl/d and beyond.
  • Treatment of fermented mash coming from molasses or juices
  • Indirect drying steam at 20 bars (natural gas or other fuels).
  • Stainless steel construction.
Benefits
  • Alcohol impregnating the yeasts is totally recovered and recycled.
  • Low DBO-DCP load of the wash.
  • Energy consumption minimized by the double effects concentration.
  • Low temperature : quality of the proteins is kept.
