Direct Heat Transfer Type Drying Process Superficial Velocity UT m/sec - As Fig.l shows, a quantity of powder is fed into the experimental apparatus which has a gas dispersion plate, such as a perforated plate at the bottom of the vessel, to emit gas from below. Movements of the powder bed with a slow increase in the gas velocity are observed as described below. At that time, the pressure loss of the powder bed is as indicated in Fig.2. While gas velocity is low. the powder bed remains still. (Refer to Fig.l a.) tatic Bed At this time the gas flows through the powder without moving the bed....

The Fluidized Bed Dryer boasts high drying efficiency through active gas contact with powder material. Batch Type Drying gas is blown up from below a perforated-plate type gas dispersion plate located at the bottom of the unit, for uniform dispersion. The processed material is batch fed into the uniform gas stream to be dried for a set time. The dried product is discharged by one of the Reverse Turning Bed Type The gas dispersion plate (the reverse turning bed) is turned 90 degrees using a control motor to discharge all dried product at one time. In general, dried product is discharged into...

In addition to standard types, variations can correspond to drying, cooling, and other functions: O Solvent drying and dust-explosion protection with a nitrogen gas closed-circuit system. © To built-in heat transfer tubes and panels. 0 Cleaning mechanism suitable for CIP. O GMP specification type for medicines. Drying, Cooling, Heating of Synthetic resin (PET, Food, Medicine, Chemicals, Fertilizer, Agriculture chemicals, Ceramics. Pigment, etc. and PET B-FBD-R Type •Fluidized Bed Dryer with agitator to promote fluidization To promote fluidization of material that has a high moisture content...

The Fluidized Bed Dryer is suitable for uniform drying of processed material with a comparatively high moisture content, bringing it to a low moisture content. Continuous Type Hot air is blown up from below the gas dispersion plate with a type of perforated plate located at the bottom of the boxed-shaped Dryer, and is dispersed uniformly. Wet material is continuously fed in a fixed quantity and is dispersed uniformly by the disperses The processed material exposed to hot air moves to the next drying chamber through a gap at the bottom of the partition plate, and after it is finally dried,...

by the overflow gate. The discharge of coarse particles with a fixed quantity from the underflow gate prevents poor fluidization and ensures stable © The perforated plate with fixed direction ensures readily discharge of the product. • Features of the Heat Transfer Units Built-in 0 As the heat transfer from heat transfer units is large, the volume of hot air can be decreased, and the system and its auxiliary equipment can be made compact. © This is an energy-saving dryer that can reduce consumption of utilities such as motive power and © The heat transfer units are built for easy removal....

Factors Applied to the Fluidized Bed Dryer Although the range of factors generally applied to Fluidized Bed Dryers can be listed below, we make it our practice to custom design and manufacture the dryer according to the physical properties of the raw material to be dried. Particle size of raw material In general, particle sizes applied range from fine powder of 20—40 microns to granules of 4~Bmm. However, particle sizes are greatly influenced by the moisture content. For instance, fine powder with a high moisture content has the potential to cause channeling and classifying phenomena,...
