Continuous Solvent Extraction Plant

olvent Extraction Plants process mainly comprises of the following steps:
a. Preparation of Oil CakeSeeds suitable for Solvent Extraction Plants to remove oil and produce defatted meal.
b. Hexane Solvent Extraction Plants of the material obtained from Step-A by using food grade n-hexane as solvent.
The Extractor is a slow moving articulated band conveyor inside a totally enclosed chamber. The band conveyor is lined with perforated sheet, covered with stainless steel wire mesh for easy percolation of Miscella. The Band Conveyor moves on the rail provided inside the solvent extractor. A series of sprays are located above the band conveyor for spraying miscella and solvent on top of the moving material bed of the extractor. During the movement of the bed through the extractor it is washed continuously at various points with miscella of decreasing concentration and finally with a fresh solvent extraction plants in a counter current manner by means of sprays kept in a line over the meal bed. The miscella percolates through the meal bed, pass through bottom and collects in various hoppers kept below the bed which ultimately flows to the miscella holding tank. The extracted meal from the band conveyor falls into the discharge bin conveyed to the desolventising section by vapour seal chain conveyor.
