Below is a list of Fluid Bed Dryers manufacturers from Millis, Massachusetts. Fluid bed dryers force heated gas through a permeable surface where it comes into direct contact with a bed of solid materials, causing the moisture inside them to evaporate. The wet material rests on the surface of a perforated plate and hot gas - usually air – rises up through the holes. Fluidization is achieved when the solid materials display fluid-like behaviors, such as the ability to flow. As the temperature and pressure rises, evaporation occurs and moisture inside the materials becomes a gas and diffuses with the air. Dehydration can also occur if the materials are dried long enough.
