Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – your trusted manufacturer of advanced industrial evaporation and crystallization solutions. Since 2015, we have been dedicated to engineering high-performance equipment for global clients. Our Multi-effect Evaporation Concentration Crystallizer with Temperature Control and Vacuum System – 304 Stainless Steel is a premier solution designed for efficient, energy-saving concentration and crystallization of various liquid solutions. This system integrates multi-effect evaporation technology, precise temperature regulation, and a robust vacuum environment to achieve superior product quality and operational reliability. Whether you are in the chemical, pharmaceutical, food, or wastewater treatment industry, this crystallizer offers a cost-effective way to recover valuable solids and reduce waste volume.
Built with 304 stainless steel for excellent corrosion resistance and durability, our crystallizer ensures long service life even under harsh process conditions. The multi-effect design significantly reduces steam consumption compared to single-effect evaporators, leading to lower operating costs. The integrated vacuum system lowers the boiling point of the liquid, allowing gentle evaporation at lower temperatures – ideal for heat-sensitive materials. With precise temperature control via PLC and HMI, operators can easily adjust parameters to meet specific product requirements. This machine is fully customizable in capacity, heating method, and automation level to suit your production scale.
Key Features & Technical Specifications
- Multi-effect evaporation – up to 3–5 effects for maximum energy efficiency (steam consumption reduced by 60–80% compared to single-effect).
- Vacuum system – water ring vacuum pump or steam jet ejector, maintaining stable vacuum level (e.g., -0.08 to -0.095 MPa).
- Temperature control – PID controller with PT100 sensor, accuracy ±0.5°C, temperature range 40–120°C (adjustable).
- 304 stainless steel construction – all wetted parts, including shell, tubes, and separator, made of high-quality 304 SS.
- Automatic operation – PLC + HMI touch screen, with data logging, alarm, and remote monitoring capability.
- Compact design – skid-mounted or floor-standing, easy to install and maintain.
- Customizable heating source – steam, thermal oil, or electric heating (optional).
- Wide application – suitable for solutions with low to medium viscosity, such as salt solutions, organic solvents, wastewater, food extracts, etc.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between multi-effect and single-effect evaporation?
A: Multi-effect evaporation uses the vapor from one effect as the heating medium for the next effect, significantly reducing energy consumption. Our crystallizer can achieve 60-80% steam savings compared to single-effect designs. -
Q: Can this crystallizer handle heat-sensitive materials?
A: Yes. The vacuum system lowers the boiling point, allowing evaporation at temperatures as low as 40°C, which is ideal for heat-sensitive pharmaceuticals, food extracts, and biological products. -
Q: What is the maximum capacity available?
A: Standard capacities range from 100 L/h to 5000 L/h. Larger capacities can be custom-designed based on your project requirements. -
Q: Is the temperature control accurate?
A: Yes, we use a PID controller with a PT100 temperature sensor, providing accuracy of ±0.5°C. The control system can be fully automated to maintain stable conditions. -
Q: What materials are used for construction?
A: The standard material is 304 stainless steel for all wetted parts. For more corrosive applications, optional upgrades to 316L or duplex stainless steel are available. -
Q: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation guidance, commissioning, and training for your operators. Remote technical support is also available via video call. -
Q: What is the lead time for delivery?
A: Typical lead time is 30-60 days depending on the complexity and capacity. We can arrange expedited production for urgent orders. -
Q: Is the equipment CE certified?
A: We can provide CE certification upon request. Our factory also holds ISO9001, ISO14000, and other certifications. Please contact our sales team for specific documentation.
