ATFD has a Single Point Solution for all Drying Applications

Posted by SVAARProcess on November 10th, 2020

Agitated Thin Film Dryer (ATFD) for evaporation of water/solvents to make concentrated liquid to dry powder or flakes. Based on application either recovered solvent or dry product is important. Agitated Thin Film Dryer design is the ideal apparatus for continuous processing of concentrated material for drying. Agitated Thin Film Dryer consists of a cylindrical, vertical body with heating jacket and a rotor inside of the shell which is equipped with rows of pendulum blades all over the length of the dryer. The vapors make rise up, counter-concurrent the liquid and go through the Cyclone separator affixed on the ATFD vapor outlet. These vapors will be condensed in condenser and found as condensate. The system will be functioned under vacuum for temperature-sensitive products, and atmospheric status for the normal drying.

Agitated Thin Film Dryer(ATFD) for evaporation of water/solvents to make concentrated liquid to dry powder upto 5% moisture . Based on application either recovered solvent or dry product is important.Agitated Thin Film Dryer design is the ideal apparatus for continuous processing of concentrated material for drying. Agitated thin-film evaporation has been very successful with difficult-to-handle products. Simply stated, the method quickly separates the volatile from the less volatile components using indirect heat transfer and mechanical agitation of the following product film under controlled conditions.

Agitation of the following product film under controlled conditions

Agitated thin film evaporators are typically used for fluids which are difficult to handle due to higher sensitivity and viscosity. Such an evaporator consists of two key components: a jacketed shell and a rotor which rotates at high speed inside the shell. The feed is inserted into the mechanism at the top. Then, it is distributed along the shell via a distributor. After this, the rotor works to spread the feed into a thin film and agitate it further. The liquid is distributed in the form of a thin film on the heated wall where the heat transfer takes place.

BENEFITS
