Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – your reliable partner in advanced process equipment. Our Low-Temperature Evaporation and Crystallization Equipment is specifically designed for the pharmaceutical and food industry concentration applications. With years of expertise in environmental technology and a strong focus on energy efficiency, we deliver solutions that protect heat-sensitive products while achieving high concentration ratios. Built with premium materials and intelligent control, this equipment ensures consistent performance and operational safety.
Our system operates under mild thermal conditions (typically 40-80°C), which is ideal for concentrating heat-sensitive pharmaceutical intermediates, botanical extracts, fruit juices, dairy products, and other food ingredients without degrading their quality. The integrated crystallization function allows simultaneous concentration and crystal recovery, greatly simplifying downstream processes.
Key Features & Technical Specifications
- Low-Temperature Evaporation: Utilizes vacuum-assisted falling film or forced circulation technology to evaporate water at reduced temperatures, minimizing thermal damage.
- Efficient Crystallization: Combines evaporation with controlled cooling or evaporative crystallization to produce uniform crystals, suitable for API purification, sugar recovery, and salt separation.
- High Concentration Ratio: Capable of concentrating solutions up to solid content of 60-80% depending on product characteristics.
- Energy Saving Design: Optional heat pump or mechanical vapor recompression (MVR) integration reduces steam consumption by up to 50%.
- Sanitary Construction: All product-contact parts are made of SS316L with mirror polish (Ra ≤ 0.6 μm), fully compliant with FDA and GMP requirements.
- PLC Automated Control: Touch screen interface monitors temperature, pressure, liquid level, and flow rate in real time; data logging and remote monitoring available.
- Flexible Capacity: Standard models from 100 L/h to 5000 L/h; custom designs available upon request for larger or smaller scales.
Below is a summary of typical technical parameters (for reference, configurations may vary per customer requirement):
| Parameter | Value Range | Remarks |
|---|---|---|
| Evaporation Temperature | 40 – 80 °C | Adjustable via vacuum level |
| Operating Vacuum | -0.08 to -0.098 MPa | Customizable |
| Material of Construction | SS304 / SS316L / Hastelloy | Depending on corrosiveness |
| Power Supply | 380V / 50Hz (three-phase) | Other voltages available |
| Crystallization Method | Cooling or Evaporative | Based on solubility curve |
Client Benefits

Frequently Asked Questions (FAQ)
-
Q: What is the typical temperature range for this equipment?
A: The equipment operates at temperatures between 40°C and 80°C, depending on the product's thermal sensitivity and required vacuum level. Lower temperatures can be achieved with deeper vacuum. -
Q: Can this system handle both evaporation and crystallization simultaneously?
A: Yes. The process combines concentration through evaporation with controlled cooling or evaporative crystallization to produce solid crystals directly from the concentrated solution. -
Q: What materials of construction are available for corrosive products?
A: We offer SS304, SS316L, and Hastelloy alloys based on your product's pH and chloride content. For pharmaceutical applications, SS316L with electropolished surfaces is recommended. -
Q: How do you ensure the system meets GMP or FDA requirements?
A: We design the system with sanitary welds, sloped drains, 3A or Dairy standards, and complete documentation (material certificates, surface finish reports, and IQ/OQ protocols) upon request. -
Q: What is the maximum solid concentration achievable?
A: Typically up to 60-80% total solids, depending on the product's viscosity and solubility characteristics. For very viscous materials, a scraped-surface evaporator option is available. -
Q: Can the equipment be customized for different production capacities?
A: Absolutely. We offer standard capacities from 100 L/h to 5000 L/h and can design larger or smaller units based on your specific process requirements. Pilot-scale units are also available for testing. -
Q: What after-sales support do you provide?
A: We provide on-site commissioning, operator training, a 12-month warranty, and remote technical support. Spare parts are readily available from our stock in Qingdao. -
Q: What certifications does your company hold for this equipment?
A: Our quality management system is ISO9001 certified. We can also provide equipment with CE marking, HACCP compliance, and other specific certificates upon request.
