Multi Effect Evaporators (MEE)
Multiple effect evaporators are used to increase the solid concentration of milk from 4-6% to 44% through evaporation. Multiple effect evaporators are commonly used due to their higher energy efficiency.
Against design evaporators operate at much lower steam economy, productivity and outlet concentration due to steam system bottlenecks and conventional controls. Variations in steam pressure and flow, vacuum, inlet concentration, feed temperature, flow between effects, cooling water temperatures, among other factors hamper evaporation.
Our Solution:
Forbes Marshall provides a solution designed to enhance and manage evaporator performance. The control philosophy focuses on optimising the steam flow for each feed flow range in order to achieve optimal steam economy while ensuring desired evaporation, product specific gravity and consistent calendria levels.
