Introduction:
Looking back: Clients and colleagues often ask us:
“Qungan Drying has been around for many years; what truly outstanding work have you done in the field of industrial drying?”
Our answer is simple:
Understand the customer’s true needs and fulfill them as much as possible.
Industrial drying is far more than just a process of heating and drying; it involves energy efficiency, environmental standards, and high-quality production benefits. The Qungan Drying system adheres to the principles of “long-term vision, rapid implementation, fine processing, and continuous improvement,” consistently introducing advanced drying and granulation technologies from home and abroad to systematically address the existing shortcomings of domestic rotary flash dryers and roller drying granulation technology.
Through continuous technical improvement and enhancement, Qungan’s material testing reactions can overcome challenges related to high temperatures, high viscosity, and “heat-sensitive materials” under rigorous oxygen conditions.
Taking the current pharmaceutical industry as an example: equipment must not only meet GMP requirements but also pass safety inspections.
For example:
1. Material Selection: All surfaces, whether in contact with materials or not, are manufactured using high-quality 30408 stainless steel.
2. Joint Design: Internal surfaces and weld points are smoothly ground to reduce any contamination or contact retention.
3. Automatic Control System: Qungan Drying utilizes an integrated touch screen system: Siemens PLC system, achieving intelligent temperature control. Vacuum adjustment and gas distribution supply can be freely adjusted for real-time monitoring.
In practice, the MZG low-temperature pulse vacuum dryer combines vacuum-driven step-by-step drying, hot air bubble suppression, and a progressive layered ventilation system, merging vacuum technology with heat transfer technology. This equipment not only excels in on-site temperature measurement but also meets requirements for drying efficiency and energy conservation.
The CT-C series hot air circulation dryer features a fully welded rounded internal wall structure. Within most of the hot box circulation, energy utilization is as high as 70%, fully meeting the high-quality drying requirements of the pharmaceutical and medical industries.
For a good industrial drying machine to be effective, beyond elegant electronic control programming, it tests the craftsmanship of the mechanical structure.
In addition to an electrical team proficient in PLC, Qungan Drying is equipped with veteran assembly masters with 15-20 years of welding experience. From the routing of circuits to the joining of welds, every detail is strictly controlled. This is all to deliver the highest quality equipment to our customers.
Conclusion:
Qungan understands that for every type of material entering the machine, how heat conduction is calculated and how fluids flow,
the data is completely different, which is why we customize.
Because we deeply understand our customers’ pain points, we modify our designs wherever the customer’s production line faces bottlenecks. Our long-term partnerships with major factories like Hainan Senqi Pharmaceutical and Yinchuan Hospital of Traditional Chinese Medicine do not rely on empty words, but on high customization capabilities and a professional after-sales team.
There are no shortcuts in manufacturing industrial drying equipment; it is all about the details.
