The most crucial principle driving the Operating of the fluid mattress dryers is, Air is allowed to flow via a mattress of stable powdered content within an upward course. This produced so which the velocity is higher compared to the setting price of all particles.
This point out of fluidization makes sure that the merchandise particles are surrounded by warm air, allowing for an even and economical drying system.

To grasp fluidized mattress dryers, it’s initial necessary to know the thought of ‘fluidization’. Fluidization is really a course of action that decreases the resistance of reliable particles and permits them to show fluid-like Attributes.
SS filters are made of stainless steel and also have high-quality perforations which prevent happy reduction and allow air to go. Bag filters are created of canvas fabric.
Materials: Chrome steel is the commonest substance for fluidized beds, but other supplies like carbon steel or Hastelloy may be used for here unique purposes, impacting the price.
