There are several aspects to consider when choosing between a horizontal or vertical dryer for dynamic contact drying. What material are you using? Does it have specific process parameters? Is your process a batch or a continuous one? This article describes how horizontal and vertical contact dryers work and the applications for which each dryer is best suited.
Vibratory fluid-bed dryer-coolers are gaining popularity in a large number of applications thanks to their rapid drying times and suitability for heat-sensitive materials. This article discusses the differences between circular and rectangular vibratory fluid-bed dryer-coolers and the situations in which each would be a good fit.
One factor that can greatly influence your dryer selection is the need to maintain or reduce your material’s particle size and shape during drying. In this article, columnist John J. Walsh describes a variety of dryers and how they can either help or hinder those efforts.
In this column, author John J. Walsh revisits a past discussion of typical control systems for continuous direct-contact (convection) and indirect-contact (conduction) dryers, the limitations of these control systems, and how newer technologies may be overcoming these limitations.
In this column, author John J. Walsh revisits a past column explaining questions that can help in choosing the best fluid-bed dryer for an application.
