Subcritical Extractor（Closed loop extractor） BHO extractorThe RNF series closed-loop extractor uses subcritical fluid as the extractant. In a closed, oxygen-free, low-pressure pressure vessel, based on the principle of similar intermiscibility of organic substances, the extraction material and the extractant are molecularly diffused during the soaking process to achieve The fat-soluble components in the solid material are transferred to the liquid extractant, and then the extractant is separated from the target product through the process of vacuum evaporation, and finally a new type of extraction and separation technology for the target product is obtained.Compared with other separation methods, the closed-loop extractor has many advantages: non-toxic, harmless, environmentally friendly, non-polluting, non-thermal processing, retaining the active ingredients of the extract without damage or oxidation, large capacity, energy saving, low operating cost, easy to process The product is separated. Features1、Suitable for plant extraction2、Made of 304 stainless steel3、Good sealing performance4、Efficient extraction5、Real-time observation of materials6、All interfaces are connected by high-pressure clamps, which are pressure-resistant and easy to clean
