The outstanding mixing and heat transfer skills of these devices assure uniform drying, thereby ensuring high-quality and regularity. Simplicity in design would make fluidized mattress dryers easy to work and maintain, that's why These are the preferred choice for a myriad of industrial programs.
The sucked air passes by way of a series of filters the place particles and impurities are taken out. The filtered air then proceeds to pass through a heating system where it’s heated to the desired temperature according to the merchandise’s requirements.
The dried product or service is then discharged through the dryer. The fluidized bed dryer is developed such which the air velocity minimizes in direction of the top of your drying chamber.
Fluidized mattress dryer contains a significant drying rate and the material is dried in an extremely quick time. Substance stays cost-free-flowing and uniform.
FBD will work over the Principle of Fluidization. Fluidization is a phenomenon wherein the packed mattress of damp powder particles Or particulate solids, when are exposed to a thrust and movement of hot fluid (In such cases Hot Air), flowing from the bottom on the mattress upwards, forces it to variety a flexible mattress (which appears like a Mattress of Boiling H2o), along with the mattress of floating particulate solids known as as Fluidized Bed.
Each grain is comprehensively dried by the new fuel that surrounds them. Because of this, products or granules are dried consistently
If vendor has get more info their own personal calculations offered, we must see and Examine them on our technical specs and specifications.
Sturdy heat and mass transfer costs result from fantastic fuel particle constants, which implies high dampness elimination premiums.
Purging air is provided under from your impeller to avoid stickiness inside the granules for the impeller and likewise can help protect against contamination.
1. The wet granules to generally be dried are put inside of a detachable bowl. The bowl is pushed into your fluidized mattress dryer.
Load the fabric which happens to be being dried. Drive the trolley under the retarding chamber and seal the trolley with the assistance of HMI & start out the air drying process for five-ten moment or According to BMR.
If air is allowed to circulation by way of a bed of reliable powdered substance while in the upward course Along with the velocity bigger compared to the settling price from the particles, the solid particles will be blown up and come to be suspended within the air stream.
The air inlet chamber features a fresh new air inlet, prefilter, and heat exchanger related serially to heat the air to your necessary temperature. The recent air and exit air temperature are routinely monitored in situ. Temperature sensors.
When processing poisonous or flammable substances, standard very hot air fluidized more info mattress dryers are not a great Remedy due to the fact You will find there's danger of fire or explosion if flammability constraints are exceeded.
