Our plant relies on an old batch fluid bed dryer (See Figure 1.) We can’t afford buying a new dryer, let alone its floor space. The dryer is difficult to operate because of loss of fluidization during the early part of the drying process. The baghouse employs a timer-controlled shaker that’s mechanically unreliable. When the shaker operates, the discharge valve to the blower momentarily closes. This is all that’s needed for solid to accumulate in the bowl above the screen.
