Fluid Bed Dryer/ Fluidized bed dryer:
Fluidized bed dryer (also called fluid bed dryer) is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules Drying is yew much important for wet granules for compression into the tablet and for modifying the characteristics of viscous and sticky materials. Diving is commonly the It step in unit process before compression into tablet form and packaging.

Principle:
Fluidized bed dryer is better known by name because hot air (gas) or ambient air is allowed to flow upward at high pressure through a perforated bottom of vessel containing bed of particulate solids or wet granules. The velocity of hitt air is more than the settling velocity of the granules/particles by which they remain suspended in stream of hot air. This condition is called fluidized state. The M1ot air surrounds eve, granule/particle and completely dr. Mem.

Construction:
Two types of FBI) are available, vertical and horizontal which are made up of stainless steel or plastic. Vertical type is used for batch drying and horizontal is used for continuous drying A detachable vessel is placed at the bottom of dryer for loading and unloading of material. This vessel has perforated mesh through which hot air with high pressure is passed Bag filters are placed above the vessel for collection of dried material

Working :
The material to be dried is placed in detachable vessel. bottom of the dryer. The air is introduced from below through the prefilter, which is heated by means of heaters installed therein. Simultaneously fan is also allowed to work. As the velocity of air is increased, the bed begins to expand and further increase causes turbulent motion of particles called fluidization.
T. granules/particles remain suspended in air stream. Later on, a state of pressure is reached at which frictional drag on the granules/particles is equal to the force of gravity. T. particles rise in stream of air due to high velocity of gas, this condition is called fluidised state.

Bag filters:
These are placed above the diving vessel for the recovery of particles and dried material Various features of theses filter bags
  • These are made of different types of material or fabrics- cotton, nylon, polyester, satin, polypropylene.
  • These can bear high pressure of hot air or high flow rates
  • Durable construction
  • Good resistance to wear and abrasion
  • These are available in different pm sizes, thickness, fabrics, permeability.
  • Anti-static fabrics are also available.
  • These are available in different sizes which can easily fit in equipment.

Advantages of fluidized bed dryer:
  • Thermal efficiency is 2-8 times than tray drier
  • It is available in different sizes haying drying capacity in range of 5- 250 kg/hour.
  • Free flowing granules/Pafficff 5 are made.
  • It can also be used for mixing the material with high efficiency.
  • It can be used for both batch and continuous drying.
  • Loading and unloading of material is yew easy due to detachable vessel
  • Higher drying temperatures than tray and truck dryer.

Features:
  • Tri level filtration using: 20 micron for Re Air filtration 5 micron for Secondary Air filtration 03 micron for Final Air filtration through NEPA
  • Air Dehumidification on special demand.
  • Inlet/ Outlet dampers have proportional control valve.

Vacuum Tray Dryer works under vacuum conditions on the conduction principle. Inside the dryer are several shelves having trays on which the products are placed. Top most shelf is a dummy shelf placed there to ensure proper heating and to prevent the dried powder from escaping into the solvent extraction system. Shelves are constructed hollow with baffles cum stiffeners placed in between shelves. Every shelf has an inlet and outlet nozzle and is connected to an inlet and outlet header through these nozzles.

Advantages of the Vacuum tray dryers:
  • Very efficient heat sensitive
  • Materials can be dryers in containers or enclosures
  • Average drying temperature is much lower than standard dryers
  • Drying action becomes faster as heat is easily transferred throughout the body of the dryers, due to its large surface area
  • Dries large moisture as compared to normal dryers
  • Quality of dries material is better than that of the normal dryers

Features:
  • Stainless steel construction (SS 3161/316/304)
  • Easily removable hollow pad type heating shelves
  • Dedicated fluid heating and circulating systems
  • Thermal efficiency of 60% to 80%
  • Provision for Explosion Vent / Rupture Disc on body & Validation Port on Body
  • On Chamber Vacuum break valve is provided
  • High quality interlocking for doors to chamber
  • Uniform heating flow
  • Branded immersion heaters
  • Heavy duty MS / SS door fitted on hinges
  • Single and double doors (for Large models)
  • Complete automation w/ PLC controls (Optional)

The tray dryer is the device used the drying of the wet products of the crude drugs, chemicals, powders or the granules etc. The simplest form of the dryer in this category is a cabinet with a heater at the bottom that is Laboratory oven. These ovens are of very little. value because there is no cont. of the heat transfer or humidity. If a fan is fitted to the oven the forced hot air is circulated which helps in increasing the heat transfer and also in reducing he Local vlour concentrations. Despite this there is no adequate contra. The best type of a tray dryer is that of the directed circulation form, in which the air is heated a. is directed across the material. in a controlled flow. The material. to be dried is spread on the tiers of the trays. The trays used have said, perforated or wire mesh bottoms. The screen tras are Lined with paper so that the air circulates across rather than through the drying mat... The paper is used as a disposal:ire tray Liner to reduce cleaning time and also to prevent contamination of the product. In a modern tray dryers a uniform temperature a. air is maintained by the use of a well insulated cabinet with strategically pieced fans and heating coil,. There is an alternate arrangement of the sheleves so that air can flow uniformly without any obstructions. Heater is fixed in such a way that the air is reheated before passing over each shelf. When the air passes over each shelf a certain amount a heat is given up to provide Latent heat of vaporisation. In such type a dryers there can be a good control. of heat and humidity provided it is designed correctly.

  • Door: Doors are provided at the front or rear side of the tray dryer. Door Lips are Lined with silicon rubber gasket to prevent any leakages. Suitable Locking is provided for the doors.
  • Air Circulation: Air circulation is done by specially designed recirculation blowers inside the tray dryer. The blower capacity, static & design depends on the size and model of dryer.
  • Heating: Dryers are normally supplied with either steam/ electric/thermic fluid / hot water heating system. Suitable heating coils / clarifiers are provided in the dryers.
  • Temperature Control: Temp control system is done by electronic digital temp controller fitted in the control panel. The temp control in the dryer is fully automatic.
