This paper introduces the operation guide of extraction and concentration equipment

　　The heat reflux concentration unit is a combined unit for extraction and concentration, which can be used for the new drug extraction, the determination of new technological parameters, intermediate test, the development of new varieties, the extraction of precious medicinal materials and the concentration of pharmaceutical solution.

　　The experimental equipment is suitable for the extraction and concentration of effective components of many plants, and can achieve solvent recovery and aromatic oil collection. It is especially suitable for pharmaceutical factories and scientific research institutes to develop new products and small batch production. Today, we will introduce the guide to the use of the extraction and concentration equipment.

　　1. the experimental extraction and concentration equipment has the advantages of small floor area, exquisite production, complete set and convenient operation. It is especially suitable for small batch and multi variety production.

　　2. the equipment is equipped with: vacuum pump, medicine pump, filter, receiving tank, control cabinet and other supporting accessories. The equipment can be divided into steam heating and electric heating. After the equipment is purchased, it can be used only after being connected with water, electricity or steam.

　　3. the equipment is fully functional and suitable for water and alcohol extraction, can be extracted under atmospheric pressure and negative pressure and can recover volatile oil. Equipped with vacuum converter and control box, it is easy to operate and can realize extraction at normal temperature and concentration at low temperature; Extraction at room temperature and concentration at room temperature; Low temperature extraction, low temperature concentration and other process requirements.

　　4. the electric heating structure is designed safely, heating and cooling are quick and even. The tank is equipped with a safety pressure relief device, which is safe to use.

　　5. it can realize the reflux extraction process, reduce the extraction concentration time and save the solvent.

　　6. unique oil-water separator design integrates vacuum conversion function, which makes oil-water separation effect better. Glass material is used for easy observation.
