Henan Subcritical Biotechnology Co., Ltd.

Zanthoxylum bungeanum (scientific name:
- b
- .) Alias: Zanthoxylum bungeanum, big pepper,,, or. It is a deciduous shrub that can be planted alone or used as a protective thorn hedge. The peel can be used as seasoning, extract aromatic oil, and can be used as medicine. The seeds are edible and can be processed to make soap.
-r Subcritical fluids are mainly liquefied butane and propane. The boiling points of the components in this solvent are mostly below ℃. The boiling point of propane is -.℃. The boiling point of butane is -.℃. It is a gas at normal temperature and pressure and becomes a liquid after being pressurized. The basic principle of this process is: using subcritical fluid countercurrent extraction at room temperature and a certain pressure (. etc.) Then the solvent in the mixed oil and meal is decompressed and vaporized. The vaporized solvent gas is compressed, condensed, and liquefied by the compressor before being recycled. This technology has low raw material processing costs (the cost of solvent extraction is 1% lower than the cost of supercritical extraction) and large scale (kg tons per day). The quality-preserving extraction of fats and proteins from bulk vegetable oils is unmatched by other extraction technologies. This technology is widely used in the subcritical extraction of heat-sensitive materials to ensure that the active ingredients of the materials are not destroyed by temperature. It is a technological revolution in the production industry of precious vegetable oils, vegetable proteins, microbial oils, microalgae oil and astaxanthin.

-r Patented technology for subcritical oil extraction
Advantages:
-r () Normal temperature extraction, low temperature (less than ℃) desolvation and leaching, heat sensitivity in oil and meal The substance does not damage the extract, and the pigment yield is high and the color is bright. It is an ideal process for the quality-preserving extraction of precious oils, plant proteins and natural pigments;
-r () Low solvent consumption, less than 1 ton of raw materials, solvent consumption is less than 1 ton;
-r () No steam is needed, only ℃ hot water can save % of thermal energy compared to No. 6 solvent;
-r() There is no &; three wastes pollution in production and it is an environmental protection project;
-r() Investment Small, low production cost (relative to carbon dioxide extraction equipment);
-r() Equipment with low pressure and high safety (working pressure.&;.MPa);
-r() Large production scale for complete extraction One line of equipment can reach a processing capacity of . tons &; tons/day;
-r() technology has matured and many sets of production lines have been installed since the year and a large number of listed companies have been established.
