Brand Name : RAJ PROCESS & EQUIPMENT PVT.LTD
Product Description

Our firm is acknowledged in the market as reliable manufacturer and supplier of the finest quality Agitated Thin Film Evaporator. Our offered evaporator is efficiently manufactured using superior grade components and advance technology in accordance with set market standards. The evaporator provided by us is basically used to separate a mixture of liquids having different boiling points. This evaporator is also used to increase the concentration of liquids. Beside this, we provide this Agitated Thin Film Evaporator in different models and technical specifications at nominal prices.

Features:

  • The heat transfer in 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 vacuum distillation and very short residence time the 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 horse powder requirements are very low

  • To reduce the pressure drop between the evaporator and condenser, the internal condensers can be provided to achieve short path distillation

  • The thin film evaporators are designed to handle various products with operating pressures up to O.1torr

  • Liquids with viscosity above 2,00,000cps can be handled in these evaporators.

Agitated Thin Film Evaporator

Thin film or wiped film evaporators are used to separate a mixture of liquids having different boiling points. It is also used to increase the concentration of liquids.

Principle of Operation

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 or the component with lower boiling point gets evaporated and is vacuumed out of the evaporator, while the component with higher boiling point flows down the wall and is collected at the bottom. The vapours are passed through a condenser and collected separately.

Operating Features

The heat transfer in 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 vacuum distillation and very short residence time the 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 horse powder requirements are very low. To reduce the pressure drop between the evaporator and condenser, the internal condensers can be provided to achieve short path distillation. The thin film evaporators are designed to handle various products with operating pressures up to O.1torr. Liquids with viscosities above 2,00,000cps can be handled in these evaporators.

Construction of ATFE

The Agitated Thin Film Evaporator 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 is mounted in the shell. Feed inlet is provided at the top side. Specially designed feed distributor is integral with the rotor at the top side. The rotor is also fitted with an entrainment separator. Generally the vapour outlet is provided on the top side of the shell. The different types of blade configurations available are:

  • Fixed blade rotor
  • Spring loaded rotor
  • Cylindrical wiper rotor
  • Centrifugal blade rotor

The construction of the evaporator is such that different types of rotors can be mounted in the same equipment for different products. The evaporators having surface area up to 50sq.m. can be supplied.
