Vibro-Bed employs a spraying system that introduces moisture to powdered material as it is fluidized and dried, forming agglomerates on a controlled basis. Equipped with imbalanced-weight gyratory motors and mounted on a spring suspension, the fluid bed chamber vibrates as a column of heated air flows upward through a fine-mesh screen. This causes the particles to separate and become airborne as they are sprayed with liquid. The vibratory motion of the processor also serves to convey the material along a defined pathway across the screen for uniform agglomerating and drying on a first in/first out basis. The vibratory motion also evacuates the fluid bed at the end of each cycle.
