It involves the use of a fluidized bed to suspend and agitate particles, allowing for successful drying and granulation.
A fluidized bed dryer works by passing Scorching air with large force through a perforated bed of moist reliable particles. The new air passes at a velocity higher in comparison to the settling velocity of the particles ensuing, particles beginning to suspend in the air.
To move hot air, a enthusiast is attached from the upper segment. To heat the air to the desired temperatures, a fresh new air input, prefilter, and heat exchanger are joined in sequence.
The blower constantly draws and excels air from Fluidized mattress dryer. The airstream may well comprise very compact particles identified as fines. The filter bags seize the fines of their pores but this bring about the development of a dust layer that clogs the filter bags leading to a force drop.
Damp particles hold in dry and warm air currents. By standard heating of the human body with the particle, the area dampness evaporates as heat flows through the overall body.
Fluidized Mattress Dryer here is engaged on the principle of fluidization of your feed product. Fluidization would be the introduction of incredibly hot air at higher stress through a perforated bed of moist good particles.
The Procedure of the fluidized bed dryer commences with air planning. In this period, the atmospheric air is sucked in to the dryer using a centrifugal enthusiast.
Fresh new air inlet, prefilter and heat exchanger are related serially to warmth the air to your expected temperature.
The external forces: These are indicated by labelled arrows. In a totally solved problem, a drive arrow is able here to indicating
Given that the move of air increases, the mattress expands and particles of powder start to stand up inside a turbulent movement.
Granules and hot gasoline are comprehensively blended, causing reliable temperature, chemical composition, and particle sizing distribution. Drying is attained at a relentless amount & the duration of slipping fee is fairly quick.
The precondition for an air heating unit should be to heat the main tower. Compression air inspection is done to assure that joints fashioned by inflation gaskets are leakproof.
Fluidization: It’s the process of making good sound particles behave like particles of a fluid, which freely move about, slide past each other, and perhaps collide with other molecules. Fluidization is finished by suspending good particles in a stream of fast-moving air
