The heat reflux extraction and enrichment unit is a combined unit for extraction and concentration. It uses water and other solvents to extract, concentrate, collect, penetrate, extract volatile oil, and recover alcohol from heat-sensitive materials such as plants, animals, Chinese medicine, and food additives. Widely used in the extraction of new drugs, the determination of new process technology parameters, the intermediate test, the development of new varieties, the extraction of precious herbs, and the concentration of liquid chemicals.
Heat reflux extraction and concentration equipment has the advantages of good adaptability, high paste collection rate, low energy consumption, and high degree of automation. GMP upgrades at domestic pharmaceutical companies show good adaptability and can reach higher production standards. . Compared with similar products, it has obvious advantages, so its development prospects in the domestic market are generally optimistic.
It is understood that the extraction and concentration equipment has obvious advantages in the production of Chinese medicine. According to relevant sources, as the hot solvent is continuously added to the drug surface during the extraction process, high-speed passage through the drug layer from top to bottom dissolves the solute in the drug substance, and the solute content in the drug substance and the solute content in the solvent maintain a high gradient. The solute in the medicinal material dissolves at a high speed until it dissolves completely, the effective ingredient extraction rate is high, so the rate of high paste collection and the content of active ingredients in the ointment are high. Compared with the multi-energy cans, the paste rate is increased by 10 to 15%, and the active ingredients contained in the ointment are more than 1 times higher, which reduces the loss of medicinal materials.
