Desolventiser Toaster

Desolventiser Toaster

Desolventiser Toaster

Capacity: 60 TPD to 1500 TPD

Desolventiser Toaster is designed for efficient desolventising of extracted meal.

Its is a cylindrical multistage vessel with bottom jacketed for desolventising and toasting the extracted meal, with the help of live steam following counter currently.

Mechanical/Pneumatic level controlling system maintains minimum bed height for complete desolventisation within short contact time.





Capacity: 60 TPD to 500TPD

Extractor is a horizontal model compromising articulated belt conveyor assembly, which transports the feed with a slow pre-determined speed, with an adjustable damper screw to maintain the bed height.

Series of solvent sprays through a distributor, sprays evenly throughout the bed height.




Heat Exchangers

Capacity: 30 M2 to 500 M2

These are normally shell and tube type of heat exchangers, either floating head type or fixed head type, depending upon the requirement.

Internal SS 304 tubes will be present, depending upon the heat transfer area.

Specifications of Pressure Leaf Filter:

The most economical type of pressure leaf filter is equipped with vertical rectangular filter leaves. These leaves are mounted vertically and connected to a filtrate manifold at bottom of the filter tank. Depending on the applications, this filter is equipped with a pneumatic vibrator or for dry cake discharge or oscillating spray header for wet cake discharge, or both.

Filter Leaves:

The filter leaf is the most important part of the filter. Every leaf has its own discharge nozzle, which is placed in the horizontally mounted manifold. As filtration takes place on both sides, a large filtration area is obtained in a relatively small housing.

Because of perfect combination, no deposit of the filter aid particles or impurities is possible inside frame. Provision 'o' ring ensure a perfect seal.

A filter leaf consists of several layers of mesh. The inner layer is a coarse mesh for discharge of the filtrate and the support of the outer layers. Several layers - five and above, are used for support of the gauge, depending upon individual needs.

A minimum pressure drop inside the leaves is guaranteed even at high filtration rates.

We can undertake fabrication supply of these filters with area from 2 sq. mtr. to 85 sq. mtr.
