Qingdao Conqinphi Environmental Technology Group Co., Ltd., a trusted manufacturer established in 2015 with over 200 employees and a factory spanning 10,000–30,000 square meters, proudly presents the DTB Crystallizer — a premium solution for industrial crystallization processes. This equipment is constructed from high-grade 304 stainless steel, ensuring excellent corrosion resistance, durability, and long service life. Designed with a Draft Tube Baffle (DTB) configuration, it delivers efficient mixing, uniform crystal growth, and high product purity. We back every unit with a 1-year warranty and free technical training, making it a reliable and cost-effective choice for your business.
Our DTB Crystallizer is widely used in chemical, pharmaceutical, food processing, and wastewater treatment industries. It operates on the principle of forced circulation through a draft tube, creating a controlled supersaturation environment that promotes consistent crystal size and morphology. The 304 stainless steel construction meets hygiene and safety standards, and the system is designed for easy maintenance and cleaning. Below, we highlight key features and technical specifications.
Key Features & Benefits
- High-Efficiency Crystallization: The DTB design ensures excellent mass transfer and heat transfer, resulting in faster crystallization cycles and higher yield.
- Uniform Crystal Size Distribution: The internal draft tube promotes gentle suspension of crystals, minimizing fines and producing a narrow size distribution.
- 304 Stainless Steel Construction: Resistant to corrosion from acids, alkalis, and salts; suitable for a wide range of chemical environments.
- Energy Saving: Optimized flow pattern reduces power consumption compared to conventional crystallizers.
- Easy Operation & Maintenance: Simple design with accessible components; CIP (clean-in-place) compatible.
- Free Technical Training: Our engineers provide on-site or remote training to ensure your team can operate and maintain the equipment effectively.
- 1-Year Warranty: Covers manufacturing defects and parts; extended warranty options available upon request.
- Customizable Options: Available in various sizes, heating/cooling jacket types, and control systems to match your specific process requirements.

Frequently Asked Questions (FAQ)
-
Q: What materials can be processed with the DTB Crystallizer?
A: It is suitable for aqueous solutions, organic solvents, and slurries that require controlled crystallization. Common applications include sodium sulfate, ammonium sulfate, citric acid, and pharmaceutical intermediates. The 304 stainless steel resists corrosion from many chemicals, but for highly corrosive media, optional 316L or other alloys are available. -
Q: How does the free technical training work?
A: After purchase, our technical team will arrange a training session (on-site or remote) covering operation, maintenance, troubleshooting, and safety procedures. The training duration is typically 2–3 days, and we provide manuals and video guides for ongoing reference. -
Q: Is the crystallizer customizable to different capacities?
A: Yes. We offer a range of standard sizes from 500L to 50,000L working volume. Custom sizes, jacket types, and control systems are available upon request. Please provide your process parameters for a tailored design. -
Q: What is the lead time for delivery?
A: For standard models, lead time is approximately 30–45 days after order confirmation. Customized units may require 60–90 days depending on complexity. We ship from Qingdao port, China, and can arrange sea freight, air freight, or express delivery. -
Q: Does the 1-year warranty cover all parts?
A: The warranty covers manufacturing defects in materials and workmanship for one year from the date of shipment. Wear parts (e.g., seals, gaskets) are covered for 6 months. Extended warranties are available for an additional cost. -
Q: Can I get a sample or test the equipment before ordering?
A: We welcome customers to visit our factory in Qingdao for a live demonstration. For small-scale testing, we can also provide a laboratory-scale DTB crystallizer trial. Please contact our sales team to arrange a test. -
Q: How do I maintain the crystallizer to ensure long life?
A: Regular cleaning with appropriate solvents, inspection of seals and gaskets, and monitoring of pressure/temperature are recommended. Our training covers preventive maintenance schedules. We also offer remote support and spare parts for quick replacements. -
Q: What certifications does your company hold?
A: We are certified under ISO9001, ISO14001, OHSAS18001, HACCP, SA8000, and other management systems. Our products comply with international standards. Specific certifications for your region can be provided upon request.
