Subcritical Oil Refining Equipment

XI AN BIOLAND INSTRUMENT company leverages mature subcritical fluid technology to provide customized extraction equipment, including subcritical water extraction devices, alcohol extraction production lines, and multifunctional integrated extraction systems. 

The  Subcritical Oil Refining Equipment uses automated control and has the following features:
1. High energy efficiency: Optimized heat transfer and separation design to reduce energy consumption.
2. Safe and environmentally friendly: Closed operation, solvent can be recycled, meets green production standards.
3. Flexible customization: Adjust process parameters according to customer needs, suitable for different raw materials and production capacities.
In addition, the company offers laboratory-scale, pilot-scale, and process optimization services to help customers verify technological feasibility and shorten the industrialization cycle.

In addition  Subcritical Oil Refining Equipment using propane and butane solvents that are gases at room temperature and pressure, ethanol, acetone, n-hexane, petroleum ether and other organic solvents can also be used for extraction in the subcritical state. Subcritical water extraction can also be performed with water as a solvent, and entrainment agents can be added during the extraction process. The experimental equipment has a solvent replacement design, and the solvent replacement operation is simple. According to the content of the target ingredients of raw materials, a variety of extraction solvents and extraction methods can be flexibly selected, and the selective extraction of non-polar, weakly polar and strong polar active ingredients in natural products can be obtained from oils, polysaccharides, polyphenols, alkaloids, terpenes and other components in natural products.

In  Subcritical Oil Refining Equipment , there are also devices equipped with multiple solvent storage tanks, each of which can contain a different solvent. For the same sample, we can use different solvents for extraction to obtain different extracts, or we can sequentially use different solvents to extract the same sample one after another, obtaining different extracts separately.
(1) Extraction of the same sample with different solvents, for example: subcritical extraction of cinnamon, using tetrafluoroethane to obtain small molecule essential oils, propane to obtain a fluid oil, butane to obtain a paste, and dimethyl ether to obtain liquid oil and water.
(2) Sequential extraction of the same sample with different solvents, for example: using butane to extract Sichuan pepper to obtain Sichuan pepper oil, which itself does not have the numbing taste; the numbing taste remains in the defatted Sichuan pepper after extraction. After removing the butane from the material in the extraction tank, dimethyl ether is added for extraction to obtain Sichuan pepper oil with the numbing taste, and the Sichuan pepper after dimethyl ether extraction no longer has the numbing taste.

Sequentially extract the fat-soluble, alcohol-soluble, and water-soluble components of the sample using butane, ethanol, and water. For example: for the extraction of compound traditional Chinese medicine sample A, first crush sample A into 40 mesh powder and perform subcritical butane extraction to obtain the fat-soluble components; the extract is oily or in the form of a paste (extract 1). The remaining residue B is then subjected to subcritical ethanol (95%) extraction to obtain the alcohol-soluble components (extract paste 2). The remaining residue C is extracted with subcritical water to obtain the water-soluble components (extract paste 3). By consecutively using three different solvents on one sample, three different extracts are obtained. These extracts can be directly considered for use as food or health products, or they can be further separated and purified to obtain concentrated products enriched with target compounds.
