Need For Separation

It has always been difficult to separate Solid-Liquid mixtures. Separation processes are applied to extract valuable solids , which are used in the manufacture of Medicines, Vitamins, Various kinds of chemicals.

There are three basic processes used for separation of suspended solids from a liquid media

• Sedimentation
• Filtration
• Centrifugation

Sedimentation allows solid particles, which are heavier than the liquid media, to separate and sink to the bottom of a container under the influence of gravity.

Filtration incorporates the use of a filter media by virtue of its degree of porosity and regulates what may pass through it. Since the filter media collects suspended solids, the material progressively builds up and will eventually impair performance and require removal , cleaning, and /or replacement.

Multiply the power of gravitation by 2,000 times.

Centrifugation is a highly accelerate form of sedimentation. Introducing centrifugal force to solid/liquid media generating a force that can be 2000 times more powerful than gravity itself.

Centrifuge

A Centrifugal force is a force which acts on particles moving in a circular path away from the center of the circle. This principle is used in the separation of Solids and Liquids. When a Solid-Liquid mixture in container is made to rotate about a central axis.

A Centrifuge works by spinning a vessel containing the material to be separated at high speed. The centrifuge spins at high speeds and pushes the heavy particles usually the solids to the peripheral side of the vessel.

By swinging its contents around and using their inertias to make them separate. The various items in a centrifuge have different densities. Inertia tends make each item go straight while the centripetal force caused by revolutions tends to bend them inwards.

There is a tendency for the denser items in the centrifuge to travel straighter than less dense items. As a result denser items are found on the peripheral part of the circular path and less dense ones near the center.

Dryer System

The Dryer system used by Sukhras consists of a conical vessel fitted with a helical Agitator. The Dryer system ensures complete isolation of the cake from the centrifuge and gets transferred from it with the help of a Chute originating from the centrifuge . Thus any scope of contamination can be prevented.

The inner wall of the cone is connected to a heating arrangement and is insulated from the outer wall. The agitator picks up the wet/semi-wet cake from the center and pushes it to the periphery.
