Qingdao Conqinphi Environmental Technology Group Co., Ltd. presents the Sodium Sulfite Crystallization Evaporator with automatic operation and a maximum temperature of 80℃. As a trusted manufacturer established in 2015, we specialize in advanced environmental solutions for chemical industries. This evaporator is designed to efficiently recover sodium sulfite from wastewater through precise crystallization, reducing operational costs and environmental impact. Its fully automatic control system ensures low labor intensity and high repeatability, making it an ideal choice for sustainable production.
The following table outlines the key technical specifications of our crystallization evaporator:
| Parameter | Specification |
|---|---|
| Evaporation Capacity | 500 – 5000 L/h (customizable) |
| Operating Temperature | ≤ 80℃ |
| Material of Construction | Stainless Steel 304 / 316L (optional) |
| Control System | PLC + HMI touch screen, fully automatic |
| Power Supply | 380V / 50Hz (other voltages available) |
| Crystallization Yield | ≥ 95% (depending on feed concentration) |
Key features and benefits:
- Fully automatic operation: PLC-based control system automatically adjusts temperature, vacuum, and feed rate, reducing manual intervention and human error.
- High efficiency crystallization: Optimized forced circulation design ensures uniform supersaturation, leading to high crystal purity and recovery rate.
- Low energy consumption: The system operates at 80℃ max, utilizing low-grade heat sources or waste heat, significantly reducing energy costs.
- Corrosion-resistant construction: Made of SS304 or SS316L, suitable for acidic or alkaline sodium sulfite solutions, ensuring long service life.
- Compact footprint: Integrated design saves floor space, easy to install in existing plants.
- User-friendly interface: Touch screen display with real-time monitoring of temperature, pressure, and flow rate; data logging and alarm functions.
- Customizable configuration: Options include different heating methods (steam, electric, thermal oil), vacuum system, and discharge mode (continuous or batch).
Detailed product advantages:
Our sodium sulfite crystallization evaporator is engineered to handle challenging feed streams with high salt content. The automatic operation reduces the need for skilled operators and ensures consistent product quality. With a maximum temperature of 80℃, the system minimizes thermal degradation of heat-sensitive compounds, making it suitable for pharmaceutical and food-grade applications. The crystallization process yields dry, free-flowing sodium sulfite crystals that can be directly reused or sold, turning waste into valuable resources.
Compared to traditional evaporation methods, this system offers faster start-up, stable operation, and lower maintenance. The vacuum system (optional) further lowers the boiling point, allowing operation at even lower temperatures if required. Our engineers provide comprehensive support including process design, installation guidance, and commissioning.

Frequently Asked Questions:
-
What is the maximum concentration of sodium sulfite that can be processed?
Our evaporator can handle feed concentrations from 5% to 30% sodium sulfite. Higher concentrations are possible with pre-concentration or customized design. -
Can the evaporator run continuously?
Yes, the system supports both continuous and batch operation modes. Continuous mode is recommended for large-scale production. -
What is the required maintenance schedule?
Routine inspection of seals, pumps, and control sensors is recommended every 3 months. Full system cleaning may be needed every 6–12 months depending on the feed quality. -
Is the equipment suitable for other salts besides sodium sulfite?
Yes, with minor adjustments, it can be used for crystallization of other soluble salts such as sodium sulfate, sodium chloride, etc. Please consult our technical team. -
What is the warranty period?
We offer a standard 12-month warranty from the date of shipment, with extended warranty options available upon request. -
