Alfa Laval supplies advanced solutions for heating raw juice, limed juices and other fluids containing fibres, heating clarified juice, heating and cooling syrups, molasses and other liquids with high viscosity, evaporation and condensation solutions.

Raw juice, limed juices and other fluids containing fibres 

Alfa Laval WideGap plate heat exchangers are a particularly effective solution for heating fluids containing fibres. Liquid, steam or low pressure vapour can be used as heating media. Pan vapour or vapour from the last evaporation effect are traditionally considered as waste heat, but a WideGap heat exchanger makes use of this energy. This saves the more valuable heat sources for other duties, such producing electricity that can be fed to the national grid.

Clarified juice

In sugar mills, standard Alfa Laval plate heat exchangers are a highly efficient way to heat the clarified juice, exploiting vapour bleed-offs and condensate from the evaporators as heat sources. This reduces energy consumption and maximizes the capacity of the evaporators.

Evaporation

In cane sugar mills, AlfaVap plate evaporators can be installed as complete evaporation effects or as boosters to existing Robert evaporators. The low weight, compactness and versatility of the AlfaVap design enable you to mount it virtually anywhere to extend the evaporation capacity of an existing installation.

Sugar mud from clarifier bottoms

Alfa Laval decanter centrifuges are an efficient alternative to a traditional rotary vacuum filter for dewatering sugar mud from the bottom of the sugar clarifier. This reduces energy consumption, gives a higher cake dryness and reduces sugar loss.

Syrups, molasses and other fluids with high viscosity

Alfa Laval standard plate heat exchangers provide efficient heating and cooling of high-viscosity liquids. We also supply rotary lobe pumps that are robust and durable even when handling abrasive media containing crystals.

Condensation

Ideal as a vacuum condenser, the AlfaCond plate condenser keeps the condensate separated from the cooling media. As legislation about wastewater treatment becomes increasingly stringent, this becomes an ideal option for installations where barometric condensers have been the traditional choice.
