Multi functional extraction and concentration unit for traditional Chinese medicine: practical assistance for traditional Chinese medicine production
Date: 2025-10-14Read: 0
In the production of traditional Chinese medicine preparations, extraction and concentration are key steps in transforming the active ingredients of medicinal materials into finished products. The multifunctional extraction and concentration unit for traditional Chinese medicine integrates core functions such as extraction and concentration, eliminating the need for frequent material transfer and greatly improving production efficiency. It has become a commonly used equipment in traditional Chinese medicine factories and research institutions, providing stable support for the industrial production of traditional Chinese medicine.
1、 Core Structure: Key Components for Collaborative Work
1. Extraction tank: the "extraction space" for active ingredients
The extraction tank is the core area for the reaction between medicinal herbs and solvents. It is usually made of stainless steel material, which is corrosion-resistant and easy to clean. It can adapt to various extraction methods such as water extraction and alcohol extraction. The tank is equipped with a stirring device, which can fully contact the medicinal materials with the solvent and improve the efficiency of effective ingredient dissolution; At the same time, there is a sandwich heating structure that controls the temperature through steam or thermal oil to meet the extraction temperature requirements of different medicinal materials. Some models also have condensation reflux devices to reduce solvent evaporation losses.
2. Concentrator: the "concentration core" of materials
The concentrator is connected to the extraction tank and receives the extracted liquid for concentration operation. Common ones include single effect or double effect concentrators, which use vacuum low-temperature concentration technology to reduce the boiling point of the medicinal solution while avoiding high temperature damage to the thermosensitive active ingredients in the herbs. The heating tube or heating plate inside the concentrator can evenly transfer heat, accelerate water evaporation, and the concentration of the concentrated liquid can be observed through a mirror or monitored by a concentration meter to ensure that it meets production requirements.
3. Condensation recovery system: "circular guarantee" of resources
The condensation recovery system consists of a condenser and a solvent recovery tank. During the extraction and concentration process, the evaporated solvent vapor enters the condenser, is cooled and converted into a liquid state, and then flows into the recovery tank for storage, achieving the recycling of solvents and reducing production costs as well as exhaust emissions. The system has good sealing performance, which can effectively prevent solvent leakage and ensure the safety of the production environment.
4. Control system: the "operation center" of the equipment
The control system often adopts touch screen operation, which can set parameters such as extraction temperature, time, stirring speed, concentration vacuum degree, temperature, etc., making the operation intuitive and convenient. At the same time, it has automatic control and alarm functions. When the operating parameters of the equipment exceed the set range, an alarm will be automatically issued and adjusted. If the heating temperature is too high, it will automatically cool down to ensure stable operation of the equipment and reduce manual intervention.
2、 Core advantage: Adapting to the production needs of traditional Chinese medicine
1. Function integration to improve production efficiency
The unit integrates extraction and concentration functions, and the extracted liquid can directly enter the concentration process without manual transfer, reducing material loss and operation time. Taking the production of traditional Chinese medicine decoctions as an example, traditional equipment operation requires multiple transfers of materials, while the unit can achieve continuous operation of "extraction concentration", greatly shortening the production cycle.
2. Adapt to multiple processes to meet diverse needs
Whether it is root and stem medicinal materials, flower and leaf medicinal materials, or different extraction solvents (water, ethanol, etc.), the unit can be adapted by adjusting parameters. For example, when extracting root and stem medicinal herbs, the stirring speed and heating temperature can be increased; Extracting flower and leaf medicinal materials reduces temperature, protects active ingredients, and supports multiple processes such as dynamic and static extraction to meet the production needs of different traditional Chinese medicine preparations.
3. Ensure effective ingredients and improve product quality
The vacuum low-temperature concentration technology used can avoid the damage of high temperature to thermosensitive components in medicinal materials, such as polysaccharides and volatile oils, and largely retain the effective ingredients of medicinal materials. At the same time, the contact parts made of stainless steel material are not easily reacted with the drug solution, ensuring the purity of the drug solution and providing high-quality raw materials for subsequent formulation production.
4. Energy conservation and consumption reduction, reducing production costs
Compared to single effect concentrators, dual effect concentrators can utilize the heat from secondary steam and reduce steam consumption; The solvent recovery system can recover over 80% of the solvent, reducing procurement costs. In addition, automated control reduces manual input, and long-term use can significantly reduce production costs and improve economic efficiency for enterprises.
The multifunctional extraction and concentration unit for traditional Chinese medicine has become an important equipment in the production process of traditional Chinese medicine due to its advantages of functional integration, process adaptation, and quality assurance. It not only meets the efficiency requirements of industrial production of traditional Chinese medicine, but also ensures product quality, providing strong support for the modernization development of traditional Chinese medicine.
