Microwave-enhanced filter dryer for chemical and pharmaceutical applications

Filters, Dries, and Extracts Solids from Liquids

The RoLab with Microwave from De Dietrich Process Systems is a versatile agitated Nutsche filter dryer. This equipment uniquely integrates microwave technology into the solid/liquid filtration and drying process, allowing for rapid reduction in drying times and enhanced energy efficiency. It operates under vacuum conditions, improving thermal processing through both conventional heating and microwave radiation, which penetrates deeply into the material for uniform drying—ideal for the pharmaceutical and fine chemical industries.

The RoLab is particularly effective for applications involving pharmaceuticals, plant extracts, and specialty chemicals, enhancing drying and extraction processes for products such as active pharmaceutical ingredients, intermediates, and herbal supplement powders. It can accommodate slurry, solid, liquid, and cake types, with a filter area of 0.4 m² and a maximum cake volume of 128 liters.

Designed for pilot, batch, and small-scale operations, the RoLab features reversible agitator speed control and an efficient 5.5 kW main motor. The microwave system operates at a frequency of 2.45 GHz, offering precise control over temperature and microwave power distribution, which reduces energy consumption and integrates seamlessly into your existing line. Constructed for durability and easy maintenance, the unit supports CIP requirements, ensuring contamination-free cleaning and minimal downtime.

Available in materials compatible with corrosive chemicals, the RoLab aligns with GMP standards, making it a reliable choice for labs and production facilities focused on quality and performance.
