source：www.sjbyj.com Release time：2026-10-13
1、 Characteristics of HCD vacuum low-temperature high concentration concentrator
1. Low temperature negative pressure evaporation to protect the effective components of materials
By relying on vacuum to lower the boiling point of the material, evaporation and concentration can be completed at lower temperatures, avoiding high temperatures that can cause thermal decomposition, oxidation, and coking of the material. It is suitable for heat sensitive chemical material liquids, extraction liquids, salt solutions, etc. The material has a short heating time and retains its original physicochemical properties.
2. Support high solid content concentration, less prone to scaling and pipe blockage
Adopting a thin film evaporation structure, the material liquid forms a flowing thin layer on the heat exchange surface, which can continuously concentrate the original liquid to a high concentration; The supporting scraping film structure reduces material adhesion and wall formation, solving the problem of dry heat exchange surface during high viscosity material concentration. The concentration ratio can be adjusted, and the material liquid concentration can be monitored online and automatically discharged.
3. The solvent is recyclable and operates in a closed environment
The steam generated by evaporation enters the condensation system to achieve the recovery and reuse of water or organic solvents; The whole machine operates under closed negative pressure, with no material volatilization or leakage, improving the production environment in the workshop and also suitable for handling volatile materials.
4. Continuous automated operation for easy process control
Can continuously feed and discharge concentrated liquid, equipped with vacuum, temperature, liquid level, and concentration online sensors, and PLC automatic control; CIP on-site cleaning can be set, with no cleaning dead corners, in compliance with clean production standards.
5. Strong material adaptability
The contact material part is made of corrosion-resistant stainless steel or PTFE lining, which can handle materials containing acid, alkali, and halogen salts, and is suitable for various corrosive materials such as chemical, new materials, and pharmaceutical industries.
2、 Characteristics of Flash Drying Unit
1. Instantaneous drying, short heating time
After entering the drying machine, the material stays in the high-speed swirling hot air field for only a few seconds. Although the temperature of the hot air is relatively high, the time for the material to come into contact with heat is extremely short, and the thermosensitive material is not easy to deteriorate. It can handle high viscosity slurry and filter cake after concentration.
2. Integrated crushing, drying, and grading
The bottom mixing device cuts and disperses the clumpy thick slurry into small particles; A grading ring is installed at the top of the drying chamber to intercept large particles that have not been completely dried and allow them to fall back for secondary crushing and drying. Only fine powder that meets the requirements of fineness and moisture content is collected with the airflow, producing finished powder at once, eliminating the need for separate crushing and screening processes.
3. Wide range of material adaptation
Can handle concentrated paste, slurry, and filter cake materials; By adjusting the hot air temperature, stirring speed, and grading ring parameters, the fineness and moisture content of the finished powder can be flexibly controlled.
4. Compact equipment, closed micro negative pressure operation
The whole machine occupies a small area; The system operates under micro negative pressure and is sealed, making it difficult for dust to escape and resulting in high product yield; Equipped with cyclone separator and bag filter, the exhaust emissions meet the standard. The host bearings are equipped with cooling and air seal protection to prevent high temperature wear and dust from entering the transmission components.
5. Continuous production with high heat utilization rate
Continuous feeding of concentrated slurry and continuous discharge of dry powder, suitable for large-scale production; Hot air and materials undergo turbulent heat exchange, resulting in high heat exchange efficiency.
3、 The synergistic advantage of the entire combined unit (concentration+drying line)
1. Concentrate first and then dry to reduce the water treatment load of the flash evaporation unit, significantly reduce the energy consumption of the drying section, and improve the production capacity of the entire production line.
2. The entire process is sealed and continuously transported, and the concentrated slurry is directly transported to the flash evaporation host to reduce pollution and material loss caused by intermediate transportation links.
3. The entire production line is friendly to thermal sensitive materials: the concentration section is kept active at low temperatures, and the drying section is instantly heated, balancing high production capacity and stable product quality.
4. Strong process flexibility, adjustable concentration and drying parameters, and the ability to switch between producing multiple types of materials.
