Vacuum paddle dryer for laboratory use
Laboratory-scale drying of various materials like suspensions, pastes, bulk goods, and powders frequently presents challenges such as uneven moisture distribution, temperature gradients, and high drying times. Finding a solution that addresses these issues while ensuring precise control over experimental conditions is crucial.
Mix, granulate, dry, and cool in one system
The DRUVATHERM® vacuum paddle dryer from Lödige Maschinenbau GmbH is a horizontal batch vacuum dryer specifically designed for laboratory use. This system offers a reliable scale-up for product and process development. The paddle dryer features a frequency-controlled mixing tool installed in a cylindrical mixing drum equipped with a temperature control jacket. The system ensures continual three-dimensional product movement, optimizing contact with the heat exchange surface. A high-speed chopper disperses the product during phase transitions, significantly enhancing drying capacity and reducing moisture and temperature gradients. Surfaces contacting the product are electrolytically polished, and the drum is available in sizes from 5 to 20 liters. This vacuum paddle dryer is suitable for various applications, including the chemical, cosmetic, plastic, food, pharmaceutical, and battery industries.
