Recently, the "Static Mixing Vacuum Pressure Drying Equipment," custom-built by our company for a leading domestic new materials enterprise, successfully completed all factory acceptance tests. Following successful preliminary acceptance at the client's site, the equipment has been officially loaded and shipped to the client's production facility. This successful delivery not only reaffirms our company's profound technical expertise in mixing and drying under special operating conditions but also lays a solid foundation for future deep strategic cooperation between both parties.
The client produces a high-value-added intermediate for polymer new materials. This material is characterized by high viscosity, strong heat sensitivity, and susceptibility to oxidation. Traditional drying equipment often encounters the following pain points when processing such materials:
Uneven Heating: Materials staying too long in local areas are prone to overheating, discoloration, or even coking, affecting product purity.
Mixing Dead Zones: Traditional equipment suffers from stirring dead zones, making it difficult to uniformly mix and dry viscous materials.
Unstable Batches: Difficulties in maintaining vacuum levels and fluctuations in mixing effects lead to significant variations in moisture content across different batches.
The client urgently needed a customized solution capable of achieving efficient heat and mass transfer while ensuring a low-temperature vacuum environment to prevent material degradation.
Solution: Coupling Static Mixing with Vacuum Pressure Technology
Addressing the client's specific needs, our technical team, leveraging years of experience in vacuum drying, recommended the innovative process route of the "Static Mixing Vacuum Pressure Drying Equipment." This equipment boasts the following core advantages:
High-Efficiency Static Mixing Technology: The interior of the equipment features specially structured static mixing elements. Driven by the rotating vessel, the material is continuously divided, merged, and reorganized. Even without high-speed rotating stirring shafts, this achieves "gentle" and "dead-zone-free" mixing of high-viscosity materials, effectively preventing wall hanging and agglomeration.
Uniform Heat Transfer and Vacuum Environment: An optimized jacket design ensures uniform flow of the heating medium (thermal oil/steam) and provides a large heating area. Combined with a high-vacuum operating environment (ultimate vacuum reaching XX Pa), the drying temperature of the material is significantly reduced, perfectly protecting its heat-sensitive characteristics and greatly shortening the drying cycle.
Pressure and Evacuation Cycling: The equipment supports a pulsed process of "heating-vacuum-breaking vacuum." Pressure changes promote the migration and evaporation of internal moisture within the material, resulting in drying effects far superior to traditional equipment.
Fully Sealed Anti-Oxidation Design: The entire system operates in a fully sealed state and can be purged with nitrogen protection, ensuring the material does not come into contact with external air, thereby completely eliminating the risks of oxidation and contamination.
During the manufacturing process of this project, the ISO9001 quality management system was strictly implemented. From raw material entry and automatic welding of the cylinder body to precision machining and assembly, every procedure underwent rigorous inspection by quality control personnel.
The successful delivery of this Static Mixing Vacuum Pressure Drying Equipment serves as another powerful testament to our company's strength in the fields of fine chemicals and specialty new materials.
