Given that the stream of air raises, the bed often called FBD bag expands and particles of powder begin a turbulent motion. A result of the frequent contact with air, the material receives dry. The air leaving the FBD passes throughout the filter to gather the wonderful particles of the fabric.
In this method, very hot air is launched at large tension via a perforated bed of damp solid particulate.
The dried merchandise is then discharged from your dryer. The fluidized bed dryer is designed this sort of that the air velocity lowers in direction of the highest with the drying chamber.
The dryer may be divided into many various zones with independent control of airflow and temperature in order that drying can occur at the maximum attractive amount in Every single stage devoid of sacrificing performance or harmful warmth-delicate components.
Heating and cooling program failure: The heating and cooling process inside the fluidized mattress processor can expertise failures as a result of issues such as clogging, leakage, or element failure.
The principle behind a Fluidized Mattress Dryer revolves throughout the idea of fluidization. Fluidization is often a approach during which solid particles are created to read more behave just like a fluid by passing a gasoline or liquid by way of them.
Solution: This is actually the technologies i.e. the drying of the granules as a result of passing scorching air penetrating through the granules.
A supporter is obtainable at the best of the circulating incredibly hot air. New air enters; filters and warmth exchange are related serially to heat the air to your necessary temperature.
The entrained particles continue to stick onto the inside area on the bags. Intermittently the baggage are shaken to remove the entrained particles.
two. The granules are lifted from the bottom and suspended within the stream of air this affliction is termed fluidized condition.
The detachable bowl in addition to the retaining screen is crammed with the moist granules that need to be dried. The bowl is pushed into the FBD.
Electrical power supply failure: Power source failures, for example tripped breakers or blown fuses, may end up in a complete or partial shutdown with the fluidized bed processor.
For maximum generation more info overall flexibility, GEA can supply only one fluid mattress unit or the FlexStream fluid mattress processor that combines several processes in just one piece of equipment.
Light drying: Drying of solids via fluidization is the best way in pharmaceutical industries, the moisture is carried absent by the drying air by exchanging heat in the air for the products in a specific best tie.
