Wide application of single effect external circulation concentrator
Date: 2025-08-13Read: 32
The single effect external circulation concentrator, with its characteristics of low-temperature vacuum evaporation, high efficiency and energy saving, and strong adaptability, can be widely used in the following five core industry fields:
1、 Pharmaceutical industry
1. In the field of traditional Chinese medicine, it is used for low-temperature concentration of extracts and liquid extracts to reduce the damage of thermosensitive active ingredients.
2. In the field of Western medicine: Concentrate drug solutions to improve purity, recover organic solvents (such as ethanol), and residual amounts can be less than 10mg/ml.
3. Biopharmaceuticals: Concentrate fermentation broth to extract effective ingredients, supporting small-scale and multi variety production.
2、 Food industry
1. Juice and dairy products: Low temperature concentrated juice, milk, syrup, retain flavor and nutrition.
2. Condiments and additives: Processing jam, syrup, and food additive solutions for easy storage and transportation.
3、 Chemical industry
1. Solvent recovery: Efficiently recover organic solvents such as alcohol, with a recovery concentration of 70-85%.
2. Raw material concentration: processing organic compounds, inorganic salt solutions, and chemical by-products.
4、 Environmental protection field
1. Wastewater treatment: Concentrate industrial wastewater to reduce volume and facilitate subsequent purification treatment.
2. Pollution control: Recycling organic matter from exhaust gas to reduce environmental pollution.
5、 Other industries
1. Bioengineering: Concentration of fermentation broth and extraction of active ingredients.
2. Pilot seawater desalination: Reducing salt concentration through evaporation and condensation (niche application).
Summary of Core Advantages
1. Low temperature protection: Vacuum negative pressure evaporation (60-70 ℃) ensures the stability of thermosensitive materials.
2. Efficient and energy-saving: The external circulation structure improves the evaporation speed, reducing energy consumption by 30% compared to traditional equipment.
3. Flexible adaptation: suitable for small batch and multi variety production, with convenient operation and maintenance.
Note: In scenarios such as alcohol recovery and wastewater concentration, it is necessary to cooperate with an automated control system to monitor temperature, pressure, and flow parameters in real time to ensure process stability and safety.
