Ready for transport ! Lactose drying: Lactose is a disaccharide. It is a sugar composed of galactose and glucose. Lactose makes up around 2–8% of milk (by weight). TEMA Process engineered, manufactured and installed several hygienic Fluid Bed Dryers for the drying of Lactose. The rapid heat and mass transfer rates between the product and the drying medium and rapid mixing of solids which leads to nearly isothermal conditions throughout the fluidized layer, makes the fluid bed dryer a ideal system to dry the lactose.
