Solvent Extraction Plant Manufacturer, Supplier & Exporter
Solvent Extraction Plant is the process of extracting oil from seeds and other oil containing material by addition of a solvent. Food Grade n-Hexane which is a by-product of Petroleum is used at various stages depending on the amount of oil the seeds hold. It can be coupled with an oil extraction and be used on the left over seed to ensure complete extraction of oil from the seed. Depending on the seed, Solvent Extraction method can be used on seen containing around 20% of oil.
The horizontally arranged extractor features a moving belt with controllable speed and height. The solvent is passed through the bed and the slow conveyor speed ensures proper percolation of the solvent. The process is followed by distillation of the along with washing off the solvent.
Solvent extraction consists of four main operations,
Extraction of oil from oil bearing seeds/cakes.
De-solventising of de-oiled seeds/cake.
Distillation, to separate the solvent from the Miscella.
Recover the solvent for reuse.
Salient Features of Solvent Extraction Plant:
- Continuous operation.
- Lower Solvent Losses.
- Low sediment in the final oil.
- Long Extraction time ensuring low residual oil.
- Simple, rugged design for low maintenance and reliable operator.
- Easy to transport and install.
Solvent Extraction Application:
Soya bean seed, Rice Bran and Sunflower seed cake, Castor seed cake, Mustard cake, Groundnut cake, Neem cake, Mahua cake, Palm fibre and other oilseed cake
Muez-Hest Process Of Solvent Extraction Comprises of:
- Preparatory Section
- Extraction unit
- Distillation unit
- Meal Toasting
- Recuperation unit
- Meal Finishing Section
- DTDC for large capacity plant
The prepared material from Preparatory section is received in the Feed Hopper through Rotary Valve/Plug Conveyor. The material in the hopper and the rotary valve / Plug Conveyor together constitute an effective vapour seal while the latter also serves to regulate the feed. The hopper is further provided with the special switches for high level and low level indications. The latter if energized stops the band conveyor of extractor while the high level indication, transmits an audio visual signal to Preparatory Section for preparatory operator to take corrective measures.
The MUEZ-HEST Extractor is long horizontal vessel, Rectangular in cross section in M.S. Construction. An articulated band conveyor inside the Extractor receives the material from Feed Hopper and transports it at a pre determined speed from the feed end to discharge end. The band conveyor moves over rails suitably located inside the Extractor and rides on specially constructed sprockets at either end. The speed of the band conveyor is easily adjustable within desired limits. An adjustable damper enables the regulation of height of bed of material on band conveyor.
A series of sprayers located above the band conveyor enable perfect spray of the solvent on the moving bed. Special spray breakers facilitate uniform distribution of solvent over the entire width of moving bed. Each spraying section is followed by a draining section.Fresh solvent is admitted into the Extractor near the discharge end of the moving bed of material and the full miscella is recovered from the initial stage; thus ensuring the perfect counter current flow of material and the solvent.
It is not merely a simple counter current flow. The miscella circulates in a closed circuit in each of the successive section by overflowing from each hopper of the Extractor after increasing gradually its oil content in each hopper. So in each section there is an equilibrium between the oil extracted from the seed in corresponding section and the difference in oil content of solvent overflowing the preceding hopper together with the solvent overflowing the following section.
The cleaning of the band conveyors is accomplished by high pressure jet spray of fresh solvent onto the return of band conveyor at discharge end which ensures perfect cleaning of mesh and eliminates completely the possibilities of choking of mesh and channeling.
