Solvent Extraction Plant
The prepared material is received into the OILTEK Extractor by an OILTEK Conveyor via an OILTEK Air seal in the raw material receiver section, which has an arrangement for controlling the level of material received by the Extractor.

The design of OILTEK Extractor is such that its speed is adjusted automatically depending upon the capacity being processed by means of level controllers coupled with variable frequency drive to its motor.

The Extractor chamber consists of a number of solvent sprayers which in uniform, sprays the solvent over the entire bed of raw material. The length and breadth is designed to give sufficient time for intimate contact, penetration and percolation of solvent into raw material. The Extractor is also designed with light and sight viewing glasses to view the spray distribution.

The material coming out of the spraying chamber is de-oiled material with solvent which is to be recovered in the Desolventising section where it is transported by means of a special OILTEK Solvent Seal Conveyor . The mixture of the oil and solvent called “Miscella” is collected in the Miscella tank from where it is pumped to distillation section.
Desolventising
The de-oiled meal contains about 20% - 35% solvent by weight depending on the material. The meal must be desolventised.

The basic principal involved in Desolventation is direct heating of material with steam to a temperature well above boiling point of the solvent and thus ensuring no solvent is left over in the material. Toasting is also heating the material with direct and indirect steam to remove the remaining hexane and as well toast the meal. 

Vapours of solvent are then sent to OILTEK Condensers via OILTEK Scrubber where the solvent vapour is washed, and particulars of fines are not carried to the condensers.

The OILTEK Air seals are provided at inlet and outlet of OILTEK Desolventisers to ensure an air tight arrangement. This is essential to keep the solvent loss figure down. The de-oiled and de-solventised meal thus obtained is then transported to Bagging Section.

Veendeep takes great care in designing and sizing the Desolventiser as to minimize the steam and power consumption.
