Falling film evaporator is an evaporator (evaporator), which used to be concentrated. (Concentration) increase the amount of solids
used in the food industry such as dairy products, fruit juice concentrates, such as powdered milk, sweet condensed milk, etc. The work of flim Evapoator Falling Falling Film evaporator tubes with a length of about 4-8 meters covered with steam jacket like liquid evaporates. being fed to the top Vertical movement Flows into a thin film (falling film) touches the surface heating pipe walls. In parallel with the steam. The purpose of the motion of a thin film. To increase the surface area for heat exchange between the moving water will evaporate the liquid vapor caused by heat exposure. Will be brought down with the liquid. The concentrated solution And vapor is separated below the evaporator Falling film evaporator is suitable for products with high viscosity. And because long products exposure along the pipeline will be very quick, just 2-3 seconds. Ideal for products that are not stable under heat, such as milk , juice evaporator may run consecutive series called multiple effect evaporator to optimize the use of water vapor (steam economy).
