Oliver Manufacturing Company Inc. recently introduced a new fluid
bed dryer which represents a new concept in flash or surface drying
technology. The application of the Oliver patented fan system to
produce uniform, precise air flow has allowed Oliver to create a
simple, inexpensive dryer.
Adjust each air gate of the fluid bed dryer so that the material has
just enough air to remain in a fluid state. Be careful not to open the
air gates too much. If too much air is entering via the air gates, the
material will appear to be "boiling" rather than flowing smoothly down
the deck. Areas where there appears to be too little air might be
noted. This is because the deck is not completely covered, allowing
excess air to escape through the uncovered portion. When the deck
becomes covered, the air pattern will shift to normal.
