Hot reflux extraction concentrator

technical parameter

Equipment characteristics
The amount of material added is large, and the amount of medication extracted can be doubled compared to credit standard extraction. Good process adaptability, able to operate water extraction and alcohol extraction using atmospheric pressure, negative pressure, and positive pressure processes, especially for low-temperature extraction of thermosensitive materials. High concentration and paste yield. Due to the dynamic improvement of drugs. The high solute gradient between the drug and the solvent increases the leaching driving force and improves the paste yield. More than 5-20% increase compared to conventional methods. Save solvents. Fully enclosed cycle can save 30-50%. Save time. Extraction and concentration are completed in one step, and this unit uses a reflux rate twice that of conventional methods, with the entire process taking only 4-6 hours.

Reduced energy consumption. Due to the use of secondary steam as the heat source, extraction and concentration are carried out simultaneously, and the temperature of the reflux condensate is close to the boiling temperature inside the extraction tank; Moreover, polyurethane foam is used as the insulation layer, and the temperature and vacuum degree are randomly controlled. This unit can save more than 50% of steam. The quality of medicinal ingredients extracted has been improved. Due to the short extraction time and random temperature control, the quality of the extract has significantly improved. High degree of automation. Temperature, pressure, flow rate, liquid level, and concentration can all be set, and automatic control operation is convenient with stable performance. The instruments, execution components, and PLCs are all selected domestic and foreign brands for reliability. Accelerating the concentrator allows for simultaneous discharge and feeding, making it less prone to scaling and coking.

The specific gravity of the concentrated solution can reach 1 1-1.3. Special materials (prone to scaling and coking) can be converted from natural circulation to forced circulation systems. To meet the special material needs of customers. New technologies, new processes, and new materials are widely used, and the comprehensive process performance of the unit is good. All instruments, equipment, pipelines, and other materials that come into contact with drugs and solvents in this unit are made of high-quality stainless steel.

There are no dead corners inside, polished to a mirror finish, easy to clean; The sealing of the bottom cover has been changed to pneumatic sealing, which improves reliability; Replace the extraction tank with dual filter layers to prevent clogging; The extraction tank and separator are both equipped with double acting inertia demisters, and the heater adopts high smoothness thin-walled small-diameter seamless pipes with double tube pass, which has good heat transfer effect. The system is equipped with a thermostat, industrial computer and other configurations, making the process of this unit reliable and the stability of operation ahead of other similar units in China.
