Detailed Product Description

Principle: The liquid feed is distributed on the heated wall of the evaporator to form a uniform thin film with the help of suitable configuration of blades. the volatile component with lower boiling point gets evaporated and is vaccumed out of the evaporator, while the component with higher boiling point flows down the wall and is collected at the bottom.

Operating Features:The heat transfer in the thin film evaporator is very quick and efficient, thus demanding lower surface area and heat input as compared to other types of evaporator.

due to high vaccum distillation and very short residence time thin film evaporator are suitable for handling wide range of heat sensitive, high boiling and viscous feeds. Due to low rotor speeds in the range of 100 to 150rpm, the HP requirements are very low.

Construction of ATFE: Its consists of a jacketed shell having a machined surface on the inner side. the rotor assembly consisting of different configuration of blades depending upon the nature of product mounted on the shell. Feed inlet is provided at the top side.

Different types of balde configurations:

1. Fixed blade rotor

2. Spring loaded rotor

3. Cylindrical wiper rotor

4. Centrifugal blade rotor
