The posture of Heaters must be adjusted to get desired stream of air with the desired temperature. It ought to be adjusted as that neither should be quite closed nor away. Whether it is put too much shut into the outlet of your blower, then the specified temperature won't be accomplished.
The air velocity and temperature are vital in this process to ensure the particles current from the product bed continue being within a suspended condition, Hence accomplishing fluidization.
Select the BAG LOCK icon to lock the finger bag assembly and RELEASE icon to unlock the finger bag assembly.
Due to the dryer’s small drying time and excellent mixing motion, no warm places are generated, and higher drying temperatures may be accomplished.
As the moist particle suspends in scorching air, the moisture written content of stable particles cuts down to realize the specified loss on drying (LOD). The drying vapors have the vaporized liquid far from the moist solid particles. Occasionally, the leaving gas is recycled to conserve Vitality.
An increase in the bubble dimension on the mattress happens with an increase in the air velocity. The features of your fluidized mattress dryer dominates by the velocity from the gas than the temperature.
Plenum chamber is interlocked and sealed with Product or service Chamber with the assistance of the inflatable gasket (usually food items quality silicon).
Improved gasoline handling is needed as a consequence of considerable exhaust gasoline recirculation for top thermal efficiency Procedure.
Envision a large cylindrical tank stuffed with moist get more info powders or granules product, suspended in very hot air! That’s kind of what it looks like inside of or Imagine a picture a magical dance exactly where very small particles float over a cushion of air, making certain uniform drying and avoiding clumping.
two. Content of Building: The appropriate MOC choice is vital with regard to the adherence to the standard and system parameters, in addition to, longevity of the FBD.
The FBD is made of an Air inlet chamber – to permit incredibly hot air for drying, a Removable bowl to carry content to dry, a Drying chamber – to fluidize more info damp content, along with a Finger bag – to Recuperate the fines generated when the fabric is inside a fluidized condition; And at last, a supporter to aid hot air recirculation and likewise served as an outlet.
Once the gas or air velocity is elevated, it reaches a point where by the drag power exerted to the particles overcomes their body weight, causing them to become suspended while in the fluidized mattress.
Soon after completion of exercise alter the position of area and affix dully filled and signed status label within the FBD.
The fluidized mattress supplies a perfect surroundings for heat and mass transfer due to its superior floor location and efficient mixing. Given that the particles are suspended and agitated, the drying or granulating medium can penetrate the mattress, quickly transferring warmth for the particles and evaporating moisture.
