Vaccum Batch Extraction System
SSP's batch type extractors consists of a steam jacketed cylindrical pan with a top feed part for raw material loading. A hydraulically openable bottom to discharge the wet residue after extraction is also available. A vacuum condenser line from the top of the extractor recovers product aroma, organic solvents or essential oils.
01.High Pressure Extraction - Single or Multiple Columns (7-8 Stages)
Pre sized or crushed feed material is weighed and charged into SSP's stainless steel extractor columns which are connected in series. Extraction temperatures and the number of columns can be customized per the process requirement. This type of high pressure extraction columns are very useful for the products which requires leaching of soluble matters with greater degree of hydrolisation by pressure, temperature. The extractor is available as semi-automatic or a fully PLC controlled system.
02.Continuous Counter Current EXTRACTION System-Single Stage / Two Stages
In the continuous counter current type extraction system, the feed is transferred through a controlled screw feed conveyor. Pre sized herbs will be fed at the lower end of the extractor and hot water / organic solvent at the top end of the extractor. The residence time for solid liquid extraction can be controlled as required for different raw materials. The same extractor is also used for liquid-liquid extraction for separation of different active components in two liquid phases.
All the variables such as temperature of extraction, time required for extraction process, raw material feed rate and solvent media feed rate is controlled through the PLC program.
