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.
