Industrial Flash Dryers – Dispersion Type | PCX

Flash Dryer

The PCX Flash Dryer is a dispersion type dryer designed to rapidly dry high moisture wet cakes, pastes, or slurries. High speed dispersion plates provide the mechanical input needed to handle these difficult to handle materials, without adding a carrier fluid, such as water. It is well suited to dry temperature-sensitive or organic materials, such as food fibers, vegetable proteins, and yeast.


  • Ideal for high-moisture and heat-sensitive feed materials
  • Intense dispersion increases product surface area to ensure rapid evaporation for high drying efficiency
  • Compact design reduces footprint requirements when compared to other flash drying technologies
  • Customizable components, such as dispersion plates, inlets, and classifier designs to best fit application requirements
  • Easy maintenance, inspection, and cleaning of internal components via a hinged access door and cantilevered shaft

Wet feed is mechanically screw fed into the inlet air stream ahead of the dryer or pumped directly into the dryer if pumpable. High-speed dispersion plates rotate and spread material into a thin layer along the periphery of the dryer. A heated air stream passes through and conveys the wet material, flashing off moisture. Material residence time inside the dryer is typically no more than 3-5 seconds. Given the high evaporation rates, evaporative cooling takes place effectively cooling the material temperatures. This effective control on material temperature enables the PCX to flash dry temperature-sensitive or organic materials.

Multiple plate designs are available to provide operational flexibility, specifically targeting product particle size. In most applications, our wide surface dispersion plates are used, which will produce a dry fine powder. If a larger granule is your target, we switch over to our knife-edge plates which imparts less mechanical force, lowering material breakage.

The PCX Flash Dryer system is just one of the thermal technologies we employ to develop industrial process systems that meet your application requirements. At Bepex, we are committed to developing the best thermal process systems using the right technology. Between our proven industrial process equipment and decades of experience serving the industry, we are able to design a drying system that is right for you.
