300XP - Multifunctional Filter & Fluid Bed Dryer System- Brochure

Product Bowl in Filter Apparatus Product Bowl in Fluid Bed Apparatus The 300XP Filter/Dryer Fluid Bed System The 300XP model fluid bed is not a conventional fluid bed dryer. The 300XP model incorporates a filtration step to remove a solvent from a slurry. In filtration, a pressure difference is set up and causes the fluid to flow through a screen or cloth. The screen or cloth blocks the passage of the large solid parti-cles, which build up on the cloth as a cake. Once the solvent is physically re-moved from the slurry, the wet cake is transported in the product bowl to a fluid bed dryer. The fluid bed dryer accepts the product bowl and removes the remaining solvent with a warm gas stream. In a fluid bed, gas enters a bed of powder until the powder fluidizes. Fluidization occurs when the particles become suspended in the gas stream, and the bed of powder behaves as a boiling liquid. Depending on the gas velocity, the bed of powder behaves differently. The type of fluidized bed shown below is dependent on the gas velocity and the physical properties of the powder. Since the gas stream mixes and suspends the bed of material, fluid beds provide gentle and rapid drying applications. Filtration Apparatus Types of Fluidization Operating Parameters: ?

Solvent Recovery System 1. Fluid Bed 2. Pre-filter 3. Condenser Coil 4. Pressure Relief Valve 5. Blower 6. Solvent Recovery Tank 7. Heating Coil 8. HEPA Filter The purpose of the solvent recovery system is to remove the solvent in the inert gas stream supplied to the fluid bed dryer. In the dryer, the solvent of the material evaporates into the gas stream. An internal fluid bed filter (1) and a pre-filter (2) remove particulates in the gas stream. A condenser coil (3) lowers the temperature of the gas stream, which condenses some of the solvent onto the coils. The condensed solvent is collected in a solvent recovery tank (6). A pressure relief valve (4) downstream from the condenser coil protects the ductwork from overpressure scenario. The blower (5) recirculates the gas stream to the fluid bed. Prior to the fluid bed, the tem-perature of the gas stream is increased by the heating coil (7). A HEPA filter (8) cleans the gas stream upstream from the fluid bed. The oxygen concentration of the system is moni-tored and controlled by the control system using a dilution purge. Control System Standard Features: ? Allen Bradley PLC and touch screen panel ?
