Requirements and Solutions
Controlled Vacuum / Pressure
The PerMix Dual Vertical Paddle Mixer & Dryer operates under deep vacuum or slight positive pressure, facilitating low-temperature drying, degassing, and processing within inert atmospheres. This capability is vital for biomaterials that degrade at higher temperatures or in oxygen-rich environments. The vacuum accelerates drying processes while safeguarding the integrity of sensitive materials.
Uniform Mixing
Equipped with counter-rotating paddles within a vertical chamber, the mixer ensures homogeneous mixing even at low shear levels. This design eliminates hotspots and dead zones, producing consistent results across all batches—an essential factor for reliable research outcomes and scalable production.
Thermal Control
The system includes heated and cooled jackets that allow precise temperature regulation, even under vacuum conditions. Such thermal control is critical for reagents with narrow stability ranges and for maintaining cell viability during sterile mixing processes.
Solvent Recovery
Vacuum drying enables efficient moisture removal and seamless solvent recovery with active vapor management. This feature reduces energy consumption, minimizes environmental impact, and preserves material quality—accelerating development cycles.
Sanitary Design
Constructed from 316L stainless steel with polished finishes, the mixer features minimal dead zones and a Clean-in-Place (CIP) system. These attributes are vital for preventing cross-contamination and ensuring quick validation in biological applications.
Limitations of Standard Mixing Technologies
Traditional industrial mixers—such as ribbon, plow, or open-air paddle types—are inadequate when low-temperature drying, vacuum control, or high sterility are required. They often generate dead zones, cause thermal gradients, and impose excessive shear forces. Such shortcomings compromise purity and reproducibility in research settings where precision is paramount.
