Stainless Steel Crystallization Tank is a precision-engineered vessel designed for the controlled formation and growth of crystals from a solution. It is a fundamental piece of equipment in industries where purification, separation, and production of specific solid compounds in crystalline form are required.
Precision Temperature Control: Multi-zone jacket system
Advanced Agitation: optimized impellers
Energy-Efficient Cooling: Heat exchange systems with minimal energy consumption
Automated Control (Optional): PLC control system
CIP Integration (Optional): Automated cleaning and sterilization with spray balls
Superior Material Construction: Made from 304 or 316L stainless steel, offering excellent corrosion resistance against a wide range of chemicals, solvents, and acidic/alkaline environments. This ensures product purity and extends the equipment’s service life.
Precision Temperature Control: Designed with a cooling/heating jacket or internal coils for efficient heat exchange. Allows for precise control over cooling or evaporation rates, which is critical for controlling crystal nucleation and growth.
Optimized Mixing System: Fitted with a variable-speed agitator (optional, e.g., anchor, paddle, or turbine type) to promote uniform heat transfer, prevent localized supersaturation, and avoid crystal settling on the bottom and walls. This results in a consistent Crystal Size Distribution (CSD).
Polished Interior Surface: The internal surface is mechanically polished to a high-grade finish. This smooth surface prevents crystal adherence, minimizes fouling, and allows for easier cleaning and sterilization, crucial for pharmaceutical and food applications.
Seeding and Observation Ports: Equipped with dedicated ports for introducing seed crystals, adding reagents, and for in-process sampling. Sight glasses or light ports allow for visual monitoring of the crystallization process without disrupting the internal environment.
CIP Capabilities: The tank has a 360° spray cleaning ball, the system also can be customized with Clean-in-Place (CIP), automating the cleaning and sterilization process to meet stringent hygienic standards in GMP-regulated industries.
Robust Safety and Control (Optional): Includes safety features such as pressure relief valves, temperature sensors, and level indicators. Can be integrated with PLC/SCADA systems for full automation, data logging, and recipe management.
Stainless Steel Crystallization Tanks are indispensable in industries where separation and purification are achieved through crystallization.
Pharmaceutical Industry: Production of active pharmaceutical ingredients (APIs), antibiotics, and various intermediates where high purity and specific crystal form (polymorph) are critically important for drug efficacy and safety.
Chemical Industry: Manufacturing of organic and inorganic chemicals, such as sodium sulfate, sodium carbonate, ammonium sulfate, and various specialty chemicals and pigments.
Food & Beverage Industry: Purification and production of food-grade products like sugar, salt, monosodium glutamate (MSG), citric acid, and other food additives.
Biotechnology: Protein crystallization for research and diagnostic purposes.
Wastewater Treatment: Recovery of valuable materials and salts from industrial waste streams, promoting sustainability and reducing environmental impact.
Process Expertise: 20+ years of crystallization technology experience
Energy Efficiency: Optimized cooling systems reduce operating costs
Regulatory Compliance: Meets CE, GMP standards
Lifecycle Value: Durable construction with long service life
Custom Solutions: Tailored designs for specific process requirements
Constructed primarily from high-grade stainless steel (such as 304 or 316L), these tanks are built to withstand the demanding conditions of industrial crystallization processes. They are equipped with advanced control systems to meticulously manage critical parameters including temperature, cooling rate, agitation speed, and seeding. This ensures the production of crystals with consistent purity, desired size distribution (CSD), and optimal morphology.
These tanks are available in various configurations (batch, semi-batch, or continuous) and can be customized with jackets, internal coils, and specialized agitators to suit a wide range of chemical processes and production scales.
