Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – your trusted manufacturer of advanced wastewater treatment solutions. Our Freeze Crystallization System for Food Processing Wastewater Treatment, constructed from high-grade 316L Stainless Steel, is designed to meet the most stringent industry standards. This innovative system efficiently separates contaminants from wastewater using natural freezing principles, delivering reliable performance and significant cost savings for food processing facilities worldwide. With over 8 years of manufacturing experience, a factory spanning 10,000–30,000 square meters, and annual exports exceeding US$10 million, we are committed to providing sustainable, standard-compliant solutions that protect your business and the environment.
Our freeze crystallization technology harnesses the power of low-temperature phase change to concentrate and recover valuable components while producing high-quality effluent. Unlike traditional thermal or membrane processes, this system operates with minimal energy consumption and no chemical additives, making it an eco-friendly choice for stringent discharge regulations. The 316L SS construction ensures exceptional corrosion resistance, longevity, and hygiene – critical for food processing applications where sanitation is paramount.
Key Features & Technical Specifications
- Advanced Freeze Crystallization Process: Achieves up to 95% water recovery by selectively freezing pure water, leaving concentrated pollutants for easy disposal or recycling.
- 316L Stainless Steel Construction: Resists pitting, crevice corrosion, and stress corrosion cracking in aggressive wastewater environments.
- Fully Automated PLC Control: Touchscreen interface with real-time monitoring, data logging, and remote access capabilities.
- Modular & Scalable Design: Capacities ranging from 1 m³/day to 100 m³/day, easily expandable for future production increases.
- Low Energy Consumption: Uses 30–50% less energy than conventional evaporation systems, thanks to the latent heat of fusion.
- No Chemical Additives: Zero secondary pollution – ideal for organic and high-salinity waste streams from food processing.
- Standard Compliant: Designed to meet ISO9001, HACCP, OHSAS18001, and other international standards (certifications available upon request).

Frequently Asked Questions
-
Q: What types of food processing wastewater can this system treat?
A: It is suitable for a wide range, including dairy, meat, poultry, seafood, fruit & vegetable, beverage, and edible oil processing wastewaters. It works particularly well for streams with high organic load, high salinity, or high suspended solids. -
Q: How does freeze crystallization compare to traditional evaporation?
A: Freeze crystallization uses 30–50% less energy because it leverages the latent heat of fusion rather than vaporization. It also avoids scaling and fouling issues common in evaporators, and produces no volatile emissions. -
Q: What is the typical footprint and installation requirements?
A: The system is modular and compact. A 10 m³/day unit occupies approximately 30 m². It requires a concrete foundation, power supply, and inlet/outlet piping. Our team provides layout drawings and installation supervision. -
Q: Can the system handle fluctuating flow rates?
A: Yes, the PLC control automatically adjusts the ice scraper speed and refrigeration capacity to match incoming flow variations. A buffer tank is recommended for highly variable streams. -
Q: What maintenance is required?
A: Regular inspection of scraper blades, cleaning of the cooling surface (automatic CIP cycle available), and lubrication of moving parts. Our system includes built-in diagnostic alerts to simplify maintenance scheduling. -
Q: Is the system compliant with food safety standards?
A: Absolutely. The 316L SS construction meets FDA and EU food contact material requirements. The system is designed to prevent contamination and can be integrated with HACCP plans. -
Q: What is the warranty and after-sales support?
A: We offer a standard 1-year warranty on parts and workmanship. Extended warranties are available. Our support includes remote troubleshooting, spare parts inventory, and on-site service within 48 hours for most regions. -
Q: Can I test the system with my own wastewater?
A: Yes, we provide pilot-scale units for on-site trials. Our lab can also analyze your wastewater sample and recommend the optimal configuration. Contact us for a free feasibility assessment.
