CakeStand vacuum tray dryer ergonomically design for enhanced cleanability, avoiding hidden pockets or non-accessible gaps which can make the cleaning procedure problematic.

PSL’s CakeStand Tray Dryer design overcomes the inherent difficulties of traditional tray dryers. This unique vacuum drying oven allows capacities from kilograms to large-scale and provides a homogeneous dried product thanks to a uniform direct heating system.

Despite the growing offer of more modern drying equipment combining filtration and drying such as agitated nutsche filter dryer, the Tray Dryer technology is still highly needed by many API manufacturers due to FDA validation based on this traditional method. Four years ago, PSL had the ambition to modernize this technology by enhancing its drying performance and cleanability.

This unique vacuum drying oven introduces a unique heat transfer system that ensures proven heat uniformity across all heating plates. Temperature mapping tests were performed on a 12 shelves CakeStand tray dryer showing a maximum recorded temperature variation of +/- 1.0°C. These outstanding results are achieved through the heating plates providing a direct heating under vacuum.

Total ease of cleaning is achieved by a completely open floor inside the drying cabinet with all heating plates hanging directly from the roof. The CakeStand design totally avoids hidden pockets or non-accessible gaps which can make the cleaning procedure problematic.

The innovative design of the CakeStand Tray Dryer features enhanced ergonomics through optimum tray size, pivot door design and front and back access. These valuable features ensure less opportunity for overreaching or accidental spillage.

With the increased demand for antibody drug conjugates and other highly potent compounds, more investment are made towards high-potency manufacturing and PSL adapted its offering to suit this need. As a nano-containment pioneer, PSL supply the CakeStand tray dryers in conjunction with PSL high containment isolators providing safe containment when handling highly potent APIs and other highly active or cytotoxic compounds. They can also meet sterile process requirements when necessary for drying toxic or sensitive product.
