Hot reflux extraction and concentration unitIt can be used for various process operations such as atmospheric pressure, water decoction, wet soaking, hot reflux, forced circulation infiltration, aromatic oil extraction, and organic solvent recovery in industries such as healthcare, coloring, food and beverage, animal and plant, and chemical.
Characteristics of hot reflux extraction and concentration unit equipment:
1. This equipment mainly consists of an extraction tank, an external circulation single effect concentrator, and other ancillary equipment. It has a compact structure, easy operation, and integrates extraction, concentration, and solvent recovery.
2. The equipment is fully functional and suitable for water extraction and alcohol extraction. It can perform atmospheric and negative pressure extraction and recover volatile oils. It is equipped with a vacuum converter and control box, and is easy to operate. It can achieve process requirements such as room temperature extraction and low-temperature concentration, room temperature extraction and low-temperature concentration, and low-temperature extraction and low-temperature concentration.
3. The oil-water separator consists of two glass cylinders, which prolong the oil-water separation time and improve the separation effect. It is made of glass material for easy observation.
4. At the same time of extraction, high-level gravity flow is used for concentration, and the evaporated distilled water is returned to the extraction tank for further extraction. The entire reflux process takes about 4-6 hours to reduce steam and volume loss, and shorten operation time.
5. The high concentration solvent recovered is directly sent to the alcohol preparation tank for use as a solvent in the alcohol precipitation tank or extraction tank, while the dilute concentration solvent is sent to the dilute alcohol storage tank. The solvent discharge is controlled by the control box to achieve automatic liquid discharge, reducing labor and improving solvent utilization.
6. The entire equipment is made of imported SUS304 stainless steel and produced in a fully sealed pipeline manner, which not only reduces environmental pollution but also eliminates the infiltration of heavy metals and bacteria, meeting GMP requirements.
