Lödige DRUVATHERM® VT 20 Laboratory Vacuum Shovel Dryer

Product catalog summary

Overview
The Lödige DRUVATHERM® VT 20 Laboratory Vacuum Shovel Dryer is designed for efficient and reliable drying processes in laboratory settings. It supports scale-up to production machines and is suitable for small-scale production, handling suspensions, pastes, bulk products, and powders.

Key Features

Reliable scale-up for production development under industrial conditions.
All-in-one process capabilities: mixing, granulating, drying, and cooling.
Intensive mixing to prevent temperature and moisture gradients.
Short drying times due to effective heat introduction and product movement.
Gentle thermal treatment at low temperatures enabled by high vacuum.
Economical solvent recuperation.

Standard Equipment

Industrially polished outer drum surfaces.
Electrolytically polished product contact surfaces.
Sliding machine housing for easy technical access.
Integrated control unit within the machine housing.
Double acting mechanical seals.

Mode of Operation
The dryer operates as a horizontal, batch vacuum dryer with a frequency-controlled main shaft. Shovels on the rotating shaft create a three-dimensional product movement within a heated cylindrical drum, ensuring effective heat transfer and short drying times. A high-speed chopper unit disperses lumps, increasing drying capacity and preventing temperature and moisture gradients. Fine particles are retained and recycled back into the process.

Optional Equipment

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

Applications

Pharmaceutical products and intermediates.
Cosmetics.
Chemicals and fine chemicals.
Various types of sludge.
Molding and fiber compounds.
Dyestuffs.
Fiber polymers.
Agrochemicals.
