Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 with a factory area of 10,000-30,000 square meters and over 200 skilled employees, is proud to present our Sodium Sulfite Crystallization Evaporator Fully Automatic CIP Cleaning System. This advanced equipment integrates efficient crystallization technology with a fully automated Clean-in-Place (CIP) system, ensuring high purity sodium sulfite production while minimizing downtime and manual labor. Designed for the chemical, pharmaceutical, and food industries, our evaporator guarantees consistent product quality and operational reliability.
The system utilizes forced circulation evaporation to concentrate sodium sulfite solution, followed by controlled crystallization to obtain uniform crystals. The integrated CIP system automatically cleans all internal surfaces without disassembly, reducing contamination risks and extending equipment life. With PLC-based automation, operators can monitor and adjust parameters such as temperature, pressure, and flow rate in real time, ensuring optimal performance and energy efficiency.
Key Features & Technical Specifications
- High-Efficiency Crystallization: Forced circulation design with external heat exchanger ensures rapid heat transfer and uniform crystal growth.
- Fully Automatic CIP System: Pre-programmed cleaning cycles using spray balls and circulation pumps, capable of cleaning all product contact surfaces.
- PLC Touch Screen Control: Intuitive HMI with real-time data logging, alarm management, and remote monitoring capability.
- Robust Construction: Made from high-grade stainless steel (304 or 316L) with polished internal surfaces to prevent fouling and corrosion.
- Energy Saving: Multiple-effect evaporation design reduces steam consumption by up to 30% compared to single-effect systems.
- Customizable Capacity: Standard evaporation rates from 1,000 L/h to 50,000 L/h, with tailored solutions for specific production volumes.
