This permits for productive heat transfer and uniform drying as the particles are consistently in flow. The new air passing from the mattress carries absent humidity through the soaked content, leading to speedy and successful drying. Fluidized Bed Dryers are commonly Utilized in many industries for drying granular and powdered resources.
