A comprehensive analysis of the technical characteristics and application value of small-scale Chinese herbal medicine extraction and concentration machines is as follows:

1、 Core Function Design

Multi functional integration

Small devices can simultaneously complete extraction, concentration, solvent recovery, and aromatic oil collection, supporting various processes such as water extraction and alcohol extraction, and compatible with the recycling of organic solvents such as acetone and methanol. Hot reflux technology achieves extraction and concentration linkage through a secondary steam cycle, reducing energy consumption by 30% -50% compared to traditional equipment.

Low temperature protection technology

By using vacuum negative pressure (0.05-0.08MPa) combined with external heating and natural circulation, the working temperature is controlled within the range of 30-100 ℃, effectively reducing the damage of thermosensitive components such as glycosides and volatile oils. Ultrasonic assisted extraction technology further accelerates cell wall rupture through cavitation effect, improving extraction efficiency in low-temperature environments.

Modular and flexible configuration

The equipment capacity covers 5L-500L and can be adapted for laboratory research and development or small and medium-sized trial production. The frame design supports dual mode switching of electric heating/steam heating, and the bottom casters are easy to move. The extraction tank and concentration unit can operate independently or be linked through an intelligent control system.

2、 Highlights of Technological Innovation

Intelligent control upgrade

The PLC system realizes automatic adjustment of parameters such as temperature and vacuum degree, with an error rate of less than 0.01%. Some equipment is equipped with AI visual detection and remote monitoring functions. The application of digital twin technology can simulate the entire production process and predict maintenance requirements.

Green process innovation

Nanofiltration membrane technology replaces traditional evaporation concentration and can selectively retain large molecule active ingredients (such as polysaccharides and proteins) while removing over 90% of water, avoiding component denaturation caused by high temperatures. The solvent recovery system increases the utilization rate of organic solvents by 5-10 times.

• Structural optimization design

The two-stage stirring device promotes full contact between the material and the solvent, and the special oil-water separator achieves efficient collection of volatile oil. Compact layout combined with polyurethane insulation layer reduces heat loss and lowers operational risks.

3、 Application scenario expansion

• Research and education fields

Universities and research institutes utilize their small batch and multi batch characteristics to conduct research on optimizing the extraction process of active ingredients in traditional Chinese medicine.

• Industrialization Frontier Applications

Suitable for small and medium-sized production of health products, plant pigments, etc., especially for the extraction and purification of high value-added components such as essential oils and flavonoids.

• Environmental compatibility

The fully sealed design eliminates exhaust emissions, and the stainless steel material that meets GMP standards ensures that the liquid medicine is not contaminated. Cleaning can be completed by simply opening the upper and lower covers of the heater.
