Molasses pretreatment

Principle

The molasses pre-treatment process allows the reduction of bacterial pollution and impurities. It combines a thermal treatment and a purification by decantation.
C-Molasses epuration consist in a hot decanting with low pH of the diluted molasses before their fermentation. The precipitated solids are then washed to reduce sugar losses.

Specifications
  • Low consumption of low pressure steam
  • Double static decanters 85°C – pH 2-3
Benefits
  • Enhanced fermentation thanks to the decrease of osmotic stress on yeast
  • Reduction of initial bacterial contamination of molasses
  • Reduced clogging of downstream units, mainly vinasses concentration : increased production hours
  • In case of separation, the dried yeast recovery, richer in proteins, is eased.

Molasses pretreatment

Principle

The molasses pre-treatment process allows the reduction of bacterial pollution and impurities.  It combines a thermal treatment and a purification by decantation.

C-Molasses epuration consist in a hot decanting with low pH of the diluated molasses before their fermentation. The preciptated solids are then washed to reduce sugar losses.

Specifications

  • Low consumption of low pressure steam
  • Double static decanters 85°C – pH 2-3

Benefits

  • Enhanced fermentation thanks to the decrease of osmotic stress on yeats
  • Reduced clogging of downstream units, mainly vinasses concentration : increased production hours
  • In case of separation, the dired yeast recovery, richer in proteins, is eased.
