Vinasse

Vinasses: concentration and energy and agronomic recovery

Vinasses from sugar, yeast, chicory, or other agri-food production processes can be effectively concentrated by evaporation using technologies developed by FE.

Concentration by evaporation: reduction of volumes and separation of water

Evaporation separates water from the organic and mineral matter contained in vinasses:

• Water can be directed to a wastewater treatment plant (WWTP).
• Concentrated vinasses can be recycled for agricultural spreading, reducing transportation and storage costs.

Potassium crystallization: double recovery

Some potassium-rich vinasses can be treated by crystallization, allowing:

• The separation of potassium in the form of solid fertilizer (potash)
• The use of potash-free vinasses in animal feed

Low-energy technologies

Our solutions incorporate mechanical vapor Recompression (MVR), ensuring:

• Reduced energy consumption
• Excellent thermal efficiency
• Adaptability to variations in vinasse composition

Typical applications:

• Treatment of distillery or fermentation vinasses
• Agronomic and nutritional value
• Reduction in the volumes to be transported or processed.
