Product catalog summary

Overview: The DRUVATHERM® Vacuum Shovel Dryer type VT is a laboratory machine designed by Gebrüder Lödige Maschinenbau GmbH. It is engineered for reliable scale-up from laboratory to production environments, suitable for drying suspensions, pastes, bulk products, and powders.

Key Features:

All-In-One Process: Combines mixing, granulating, drying, and cooling.
Efficient Mixing: Prevents temperature and moisture gradients.
Short Drying Times: Achieved through intensive product movement and effective heat introduction.
Gentle Thermal Treatment: Operates at low temperatures under high vacuum conditions.
Economical Solvent Recuperation: Enhances cost-effectiveness.

Applications: Suitable for pharmaceutical products, cosmetics, chemicals, fine chemicals, various sludges, molding and fiber compounds, dyestuffs, fiber polymers, and agrochemicals.

Mode of Operation: The dryer operates as a horizontal vacuum dryer for batch processing. It features a frequency-controlled main shaft with shovels that rotate within a heated cylindrical drum, creating a mechanical fluid bed for effective heat transfer. An optional high-speed chopper unit disperses lumps, increasing drying capacity and preventing temperature and moisture gradients.

Standard Equipment:

Glass bead blasted outer drum surfaces.
Product contact surfaces ground to RA<0.8 µm or Ra<2.0 µm.
Sliding machine housing for easy access.
Integrated PLC control system.
Attached vapor filter.

Optional Equipment:

Special materials for product contact parts.
GMP standards and chemical design options.
Mixing drums available in 5, 10, 20, and 50 liters.
Design for inside pressure (DRUVATHERM® type DVT).
