Agitated Thin Film Evaporator By Raj Process Equipments & Systems Pvt Ltd

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.

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.
