Within the food marketplace, fluidized bed dryers are employed for drying and cooling distinctive meals products for example corn flakes, eco-friendly tea, and fast coffee. They can be desired for their significant thermal effectiveness, speedy drying charge, and nominal hazard of merchandise degradation.
This point out of fluidization makes certain that the product or service particles are surrounded by very hot air, permitting for a good and successful drying method.
It's the A part of FBD which can be movable and has solution which is necessary to generally be dried. Soon after damp sieving of granules, granules are included into your merchandise trolley and product trolley is sealed around bowl of FBD within the drying chamber.
