working principle of air flow dryer issues

  • How to Address the Air Flow Problem in Your Dryer -

    2021-4-23 · The main principle behind the working of the fluid bed dryers is explained here. Air is allowed to flow through a bed of solid powdered material in an upward direction. This made so that the velocity is higher than the setting rate of all particles. When this happens all the solid particles will get blown up and be suspended in an air stream.

    The airflow generated by the fan is forced through the heating element by the shape of the hair dryer casing. When the air initially enters the barrel, it is much cooler than the nichrome wire, so heat flows from the wire to the air. As the air is pushed along by the fan and convection, it is replaced by cooler air and the cycle is repeated.
