A significant aspect of this process would be that the granular particles are in consistent movement during the fluidized condition, which guarantees uniform drying.

The drying process usually takes spot in a few levels until finally the top place is achieved (At the top level the strong particles moisture degree is equivalent or less than one%)

Following a while, a degree of strain is arrived at at which frictional drag over the particles equals the drive of gravity.

Clean air is allowed to pass through a prefilter prior to going through a warmth exchanger to be heated. The underside of your bowl is wherever the hot air passes via. Simultaneously fan is permitted to rotate. The air pace enhanced little by little.

Principle Fluidized mattress dryers : A fluidized mattress dryer aka. FBD is really a process in which the good particles are partially suspended in an upward-relocating gas stream passed through a perforated base from the container.

The dried product is then discharged in the dryer. The fluidized mattress dryer is intended this sort of the air velocity minimizes in the direction of the highest on the drying chamber.

If air is permitted to click here movement by way of a bed of click here strong powdered content within the upward direction Together with the velocity increased compared to settling fee on the particles, the solid particles might be blown up and come to be suspended within the air stream.

Andritz: A global technology group giving solutions for a variety of industries, including fluidized bed drying devices.

at the same time coating Resolution spray is finished on granules to coating them with the help of top rated, bottom, and tangential spray furnished With all the chamber unit.

one. The moist granules being dried are put in a removable bowl. The bowl is pushed in the fluidized mattress dryer.

Remember to convey to me presently we're experiencing a difficulty inside our company in the course of drying time fbd finger negative receiving damp or obtaining excessive moisture in higher chamber what we can easily do for correction this issue ReplyDelete

Several natural powders develop electrostatic charges during drying, which could melt away the material. Therefore, added actions are needed to give electrical earthing.

The dryer is made of SS316, an austenitic chromium-nickel stainless-steel containing a deliberate level of molybdenum, escalating standard corrosion. The construction with the Vertical fluidized mattress dryer is proven during the determine down below.

Fluidized mattress drying is broadly used for drying pharmaceutical powders and granules. It permits direct Call involving particles and heated air or gasoline, causing uniform and economical drying. Very hot air is passed through the granules in the perforated container, lifting the granules and suspending them from the air stream.
