Temperature Command: The temperature on the fluidized bed processor must be diligently controlled to circumvent overheating and the potential risk of fireplace or thermal degradation with the materials being processed. Temperature sensors and computerized shut-off devices may help to forestall temperature-related dangers.
Some supplies may possibly attrite due to the fluidized state of granules’ turbulence, producing fines.
at the same time coating Option spray is done on granules to coating them with the help of top, bottom, and tangential spray supplied While using the chamber unit.
