Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – your trusted partner in high-end pharmaceutical process equipment. Since our establishment in 2015, we have grown into a manufacturing powerhouse with a 10,000–30,000 m² factory and an annual export value exceeding US$10 million. Our team of 201–300 skilled professionals is dedicated to delivering precision-engineered crystallizer equipment that meets the most stringent GMP standards. This Pharmaceutical Grade Crystallizer Equipment is crafted from 316L stainless steel and specifically designed for API (Active Pharmaceutical Ingredient) crystallization – a critical step in drug manufacturing that demands absolute purity, reproducibility, and compliance.
Our crystallizer combines advanced engineering with industry-proven design to ensure consistent crystal size distribution, high yield, and easy cleaning. Every unit is fabricated in our ISO9001 and ISO14000 certified facility, with full traceability of materials and welds. Below, we detail the key features, technical specifications, and benefits that make this equipment the ideal choice for pharmaceutical companies worldwide.
Key Features & Technical Specifications
- Material Excellence: All wetted parts are made of 316L stainless steel (AISI 316L), providing exceptional resistance to corrosion from acids, alkalis, and organic solvents used in API crystallization. The low carbon content minimizes carbide precipitation during welding, ensuring long-term integrity.
- GMP-Compliant Design: The crystallizer features sanitary connections (tri-clamp or DIN11851), smooth internal surfaces (Ra ≤ 0.4 μm), and no dead legs to prevent bacterial growth. All seals are made of FDA-approved materials.
- Optimized Agitation System: Equipped with a mechanical seal agitator (magnetic drive optional) with variable speed control (0–500 rpm), allowing precise mixing to control crystal nucleation and growth. Impeller types include pitched blade, turbine, or anchor – customizable for your specific product.
- Heating/Cooling Jacket: A full or half-pipe coil jacket is available for efficient heat transfer. The jacket can be designed for steam, hot water, or thermal oil, with temperature control accuracy of ±0.5°C via an integrated thermostat.
- Vessel Configuration: Available in capacities from 50 liters to 10,000 liters (custom sizes upon request). The vessel can be cylindrical with dished ends (DIN 28011) or conical bottom for easy discharge.
- Accessories Included: Each unit comes with a sight glass with lighting, pressure gauge, safety valve, bottom drain valve (flush or tangential), and CIP spray ball for automated cleaning.
- Control System: Optional PLC/HMI touch screen for automated control of temperature, agitation speed, feed rate, and crystallization curve. Data logging and batch reporting are available for complete batch traceability.

Customer Benefits
- High Purity & Yield: The 316L SS construction and precise temperature/agitation control minimize impurities and maximize crystal yield, reducing waste and rework costs.
- Regulatory Compliance: Designed to meet GMP, FDA, and EU regulations, the crystallizer helps you pass audits with confidence. All documentation including material certificates, weld maps, and IQ/OQ protocols are available.
- Scalability: From lab-scale to production-scale, our modular design allows easy scale-up. We can provide matched crystallizers for multi-batch or continuous processes.
- Low Maintenance: High-quality mechanical seals and sanitary design reduce downtime. The CIP spray ball ensures thorough cleaning without disassembly, saving labor and solvent.
- Energy Efficiency: Optimized jacket design and insulation (optional) reduce heating/cooling energy consumption, lowering your operational costs.
- Global Support: With our headquarters in Qingdao, China, and a network of service partners in North America, Europe, Southeast Asia, and the Middle East, we provide prompt after-sales support and spare parts.

Frequently Asked Questions
-
Q: What is the typical lead time for this crystallizer?
A: Lead time depends on capacity and customization. For standard sizes (500–3000L), it is usually 8–12 weeks. Custom designs may take 12–16 weeks. We can expedite for urgent orders. -
Q: Can the crystallizer be used for both cooling and anti-solvent crystallization?
A: Yes. The jacketed vessel supports precise temperature control, and the feeding ports allow addition of anti-solvent. The agitator speed and type can be optimized for your specific process. -
Q: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation supervision and commissioning. Remote support via video call is also available. Our team can train your operators. -
Q: Is the equipment FDA compliant?
A: The design and materials (316L SS, FDA-approved gaskets) meet FDA requirements. We can provide a FDA compliance package upon request, including material certificates and surface finish reports. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment, covering defects in materials and workmanship. Extended warranty options are available. -
Q: Can you provide documentation for regulatory audits?
A: Absolutely. We can supply IQ/OQ protocols, material traceability certificates, weld maps, and NDT reports. Additional documentation such as validation support can be arranged. -
Q: How do you ensure the surface finish meets GMP requirements?
A: We use electrophishing and mechanical polishing to achieve Ra ≤ 0.4 μm. Surface roughness is measured with a profilometer, and a certificate is provided with the shipment. -
Q: What are the shipping options?
A: We ship from Qingdao Port. We can arrange sea freight, air freight, or door-to-door delivery. The equipment is packed in plywood crates with proper cushioning.
