Multi functional extraction and concentration unitIt is an efficient equipment that integrates extraction, concentration, aromatic oil recovery, and solvent recycling functions, widely used in fields such as Chinese herbal medicine, natural products, and food chemicals.
Core components: mainly including extraction tank, condensation recovery system, and intelligent control system. The extraction tank is equipped with a stirrer and a jacket heating device, which can achieve normal pressure, slight pressure, and dynamic countercurrent extraction. The condensation recovery system consists of a multi-stage spiral tube condenser combined with a vacuum pump group, which can effectively recover solvents. The intelligent control system integrates PLC and HMI human-machine interface, which can preset process parameter formulas and monitor temperature, vacuum degree and other indicators in real time.
Working principle: By penetrating the cell wall of medicinal materials with solvents such as ethanol and water, the target active ingredient is dissolved, and vacuum low-temperature extraction technology is used to protect thermosensitive substances. During the extraction process, the secondary steam condenses and flows back to the extraction tank, forming a solvent recycling system. For concentration, an external heating natural circulation concentrator is used in conjunction with vacuum negative pressure evaporation, and segmented temperature control is used to avoid thermal decomposition of active ingredients.
Multi functional extraction and concentration unitApplication areas:
1. Pharmaceutical manufacturing: used for extracting effective ingredients of traditional Chinese medicine, suitable for the production of injection, oral liquid and other dosage forms.
2. Food processing: can be used for extracting natural spices such as rose essential oil, with a purity of 99%, and can retain intact aromatic substances.
3. Environmental protection field: capable of treating heavy metal ions in industrial wastewater, with a large adsorption capacity and a recovery efficiency of ≥ 85% for metals such as copper and zinc.
