Industrial Atmospheric Drying Systems

Q: What is the difference between atmospheric and vacuum drying?

Atmospheric drying occurs at normal pressure and generally uses higher temperatures, while vacuum drying reduces pressure to allow moisture removal at lower temperatures.

Q: When is atmospheric drying preferred?

Atmospheric drying is often chosen for materials that tolerate higher heat and require high production throughput.

Buflovak atmospheric dryers provide efficient moisture removal for materials that can tolerate higher drying temperatures. These systems operate at standard pressure and use conductive or convective heat transfer to evaporate moisture from liquids, slurries, and solids.

Atmospheric drying technologies are often selected for high-throughput operations where reliability, scalability, and continuous processing are critical. Buflovak designs drying systems that deliver consistent product quality while maintaining efficient thermal performance.

Buflovak Atmospheric Drying Technologies

Atmospheric Single Drum Dryers (ASDD)

Single-drum dryers spread liquid or slurry across a heated, rotating drum, where moisture evaporates as the drum turns. The dried material is then scraped off as flakes or sheets, making it ideal for food, chemical, and industrial applications.

Atmospheric Double Drum Dryers (ADDD)

Double drum dryers use two rotating, heated drums to create a thin film of product between them, enabling efficient drying. This setup allows precise control over thickness and moisture, making it ideal for food, starch, and chemical processing.
