Fluid bed dryer for bulk material laboratory drying
Efficiently dry and mix organic and inorganic materials with precise temperature control, ideal for R&D labs and quality control settings striving for reliable moisture management in bulk material processing.

Dries and Mixes Bulk Materials Efficiently
The Fluid Bed Dryer TG 200 from Retsch is a laboratory-scale dryer designed to handle a diverse range of materials, including organic, inorganic, chemical, and pharmaceutical bulk quantities. Utilizing a fluidized bed process, it efficiently dries and mixes materials without localized overheating, avoiding caking and ensuring uniform moisture removal. Ideal for applications in R&D, quality control laboratories, and various industries like pharmaceuticals, food, and recycling, the TG 200 supports drying times as short as 5 to 20 minutes, contingent on product characteristics such as quantity and moisture content.
The TG 200 features a robust 1000-watt blower delivering an air volume of 185 m³/h, paired with a 2000-watt heater for optimal performance. Users can easily manage the drying process with digital controls to adjust temperature, drying time, and air flow continuously, allowing a high level of customization. Its design facilitates easy integration into bench-top operations with capabilities for continuous operation.
Designed with practicality in mind, this dryer includes configurable settings for up to 9 standard operating procedures (SOPs) and offers a wide range of containers to support various research and production needs. The use of an interval operation system allows for enhanced mixing of the fluidized bed, with an emphasis on maintenance simplicity attributed to its brushless motor. This equipment is compatible with standard electrical systems (200-240 V) and adheres to CE standards, ensuring it meets the rigorous requirements of today’s laboratory environments.
