Efficient and Energy-Saving Liquid Concentration for Starch Processing
Falling film evaporator is an advanced, highly efficient solution designed specifically for the starch industry. This vertical shell and tube heat exchanger optimises the concentration of liquids by vaporising a thin film that evenly flows along the inner walls of heated tubes. Pre-heated liquid is pumped to the top of the evaporator, where it forms a consistent film that descends under the influence of gravity and vapour flow, heated by steam on the shell side.
In the starch industry, maintaining optimal film thickness is crucial for superior heat transfer and energy efficiency. Our falling film evaporator ensures that the liquid film remains evenly distributed, preventing the lower sections of the tubes from excessive drying. This design feature guarantees consistent performance and effective separation of liquid and vapor in the calandria or a separate separator, while the condensed steam flows down the outer surfaces of the tubes.
Ideal for heat-sensitive starch products, this evaporator operates efficiently with minimal temperature differences between the steam and the liquid. It is perfect for both single and multiple effect evaporation processes, handling dilute liquids with low solid content and minimal deposit formation.
