Pan dryer
Pan dryers are vertical dryers selected when intensive mixing, efficient heat transfer and controlled vacuum drying are required. The Comber pan dryer is designed for reliable operation across pharmaceutical and chemical applications, supporting uniform drying and effective product agitation.
Pan Dryer – Comber turbodry powered by De Dietrich
Pan dryers are selected when direct product access, visual inspection and process flexibility are required. The Comber pan dryer is a batch vacuum dryer designed for applications where controlled drying and straightforward operation are essential.
The design is derived from the proven Comber filter-dryer platform, while the agitator blade geometry is specifically adapted to pan drying. The paddle design is optimised to ensure effective product agitation and heat transfer during drying, while accommodating the open vessel configuration.
Performance Driven design
Performance of pan dryers is driven by how the equipment design balances drying efficiency, accessibility to the product area and operational reliability from one campaign to the next.
Proven vacuum drying concept
The pan dryer operates under vacuum, allowing solvent removal at reduced temperatures. This supports gentle drying of heat-sensitive pharmaceutical products while maintaining predictable drying cycles.
Top-entry agitation
Agitation is provided from the top, with no mechanical components located beneath the product bed. The specifically designed paddles promote complete product agitation and uniform exposure to heated surfaces throughout the drying process.
Accessibility for inspection and cleaning
The open vessel design provides direct access to the product area, facilitating visual inspection, manual intervention when required and efficient cleaning between batches.
ATEX compliance
ATEX-compliant configurations are available where required, allowing safe operation in environments involving flammable solvents.
Trials & rentals
Pan dryer trials allow drying behaviour and mixing performance to be assessed with real products before final equipment selection. Tests can be carried out at the De Dietrich Tech Lab or directly on site using rental units, helping confirm operating parameters and reduce project risk.
Want to know more?
Within the De Dietrich portfolio, additional pan dryer configurations are available, including designs equipped with bottom-driven agitation. These alternatives allow process requirements, product behaviour and installation constraints to be addressed with the most appropriate agitation concept.
