New Subcritical Extraction Equipment

undertaking 5L-15000L 0.1t-200t per day

• The equipment can be used for projects of subcritical extraction such as oil refining project, plant protein powder, natural pigment, functional oils and fats, and Chinese medicine raw materials. 

• The main solvent is butane - we call it No.4 solvent, boiling point -0.5℃, the extraction process is under a certain low pressure ( 0.3Mpa~1.0 Mpa status to liquid ) and room temperature, comparing with the oil extraction technology hexane - No.6 solvent, the technology by No.4 solvent has some benefites such as little toxic, low energy consumption and less residual.

• We can also provide the subcritical lab test eqiupment CBE 0.5L to 200L.






















• Wheat germ focused the nourishment essence of wheat, while wheat germ oil is a kind of corn germ oil extracted fromwheat germ, which is rich in Vitamin E and phytosterol, linoleic acid, linolenic acid, 28 carbon alcohol and a variety of physiological active ingredients, theVe and phytosterol content is the highest in vegetable oils, and the unsaturated fatty acid content is up to 80%, with 50-60% of linoleic acid, has very high nutritional value, so called "crown of vegetable oil".

  Subcritical butane extraction process is the ideal way of wheat germ oil extraction method, and it has 15 years history in my company processing 100,000 tons of wheat germ material accumulated. The biggest advantage is that it'll not damage the heat sensitive ingredients in the material, and secondly, the product has less butane residual (below 1 PPM).

  In order to make this technology spread, Professor Qi Kun, the founder of subcritical butane extraction technology, is committed to the industrial research starting in 1989, more than 70 production lines have been constructed up to now, production areas involving vegetable oil, essential oil, natural pigment, plant protein, flower extract, natural spices, insect and animal oil, wood products processing, aquatic products processing, the original wool degreasing, tobacco, etc.

  The process principle of this technology is to use liquid subcritical extraction solvent counter-current to material at room temperature and under certain pressure (0.3Mpa to 1.0Mpa), extract liquor (liquid) decompress and evaporate at room temperature, making the solvent gasification and separating with the target component, then get the liquid products. Materials that were extracted (solids) decompress and evaporate the adsorption of solvent at room temperature, then get another product. Gasification of solvent is used by compression cycle with liquefaction. The whole extraction process can be carried out under room temperature or lower temperature.
