Extraction plays a vital role in food processing industries where different types of extraction equipment can be found for processes like extraction of edible oil from oilseeds, extraction of coffee for soluble coffee production, decaffeination of coffee and tea, etc. Other processes include extraction of compounds such as proteins, pectins, vitamins, pigments, essential oils, aroma compounds, flavour compounds etc. from many different materials. The efficiency of the extraction process depends on the selectivity of the commonly used solvent such as typically water, organic solvents (e.g. hexane, methylene chloride, ethyl acetate), alcohol and supercritical CO2. We offer different types of SOLTEQ® extraction equipment as follows:
This SOLTEQ® Solid-Liquid Extraction Unit has been designed for students demonstration on the extraction process whereby components can be selectively extracted from solid mixtures using a suitable solvent.
This SOLTEQ® Solid-Liquid Extraction Unit is designed for student’s demonstration on the extraction process whereby components can be selectively extracted from solid mixtures using a suitable solvent.
This SOLTEQ® Liquid-Liquid Extraction Unit is designed to demonstrate the principles and operation of liquid-liquid extraction and solvent recovery processes. The mobile unit consists of an extraction system and a solvent recovery system.
This SOLTEQ® Liquid-Liquid Extraction Unit is designed for demonstration of liquid-liquid extraction.
This SOLTEQ® Extraction Process Training Skid (Model: BP68) is a lab-scale process skid capable of carrying out liquid-liquid extraction process on partially mixable components, with the choice of using a rotating disc contactor (RDC) column or a packed column with Raschig rings. This counter-current separation process will typically form an interface level which can be observed and set around a desired height in the column, with the help of a control valve. The unit operates on a single pass without a solvent recovery system.
This SOLTEQ® centrifugal extraction unit is suitable for teaching and research on purification of food products using liquid-liquid extraction. The unit consists of three sets of centrifugal separators that use centrifugal force to separate two immiscible liquids of different densities. The light phase and heavy phase liquids enter the separator counter currently from one stage to another. A heating circulation system is provided for pre-heating the liquid streams prior to entering the separator whenever required. Instruments are also provided with the unit for the purpose of process monitoring and control.
Supercritical Fluid Extraction (SFE) is the process of extracting component from powdered solid using supercritical fluids as the extracting solvent. SFE process, on a small or large scale, can be effectively used to either strip unwanted material from a product (e.g. decaffeination) or collect a desired product (e.g. essential oils). Carbon dioxide (CO2) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol. Extraction conditions for supercritical carbon dioxide are above the critical temperature of 31 °C and critical pressure of 74 bar. Our SOLTEQ® SFE unit comes with extraction vessel from 300 to 1,000 ml in size and operates between 100 to 500 bar pressure.
