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.

Potocone Vacuum Dryer (PCVD) Rotocone Vacuum Dryer is suitable for drying of materials which cannot resist high temperature, materials which are easily oxidized, volatile materials which should be retrieved, materials that are strong irritants and poisonous in nature. The Rotocone Vacuum Dryer with improved technology integrates during operation under vacuum.
The Rotocone Vacuum Dryer facilitates enhanced drying efficiency, Low temperature operation and economy of process by total solvent recovery. It helps cGMP base working by achieving optimum dust control, while offering advantages of efficient charging and discharging of materials. The drying unit equipped with Lump breakers initially breaks Large Lumps and subsequently powders them (in a single cone). The rotary action of the dryer together with mechanical action of the breakers cuts down drying time and gives a Lump-free product.

Advantages:

• Reduces drying time
• Eliminates need for re-drying of Lumps
• Handling and exposure of final product is avoided
• Gives uniform site dry product.
• System can process crystalline or amorphous powders which are prone to Lumps
• Easy to clean internal surface ensures purity of product .
• Optimum and continuous vacuum maintenance during process
• Uniform material shuffling over the heated contact surface of the cone.

Drive:

• Gear Box & Motor Direct Coupled and Gear Box to Cone Drive shaft Bull Gear-Pinion Gear Drive.
• Extended shaft (drive side) so that drive unit can be kept in service zone (U required).
• Vacuum Loading system of wet material into the Cone.

Finish:

• Internal 320 grit mirror polish and outer 180 grit mat finish.
• VFD for Drive Motor with RPM indicator.
• Condenser and Receiver in 55316 instead of 55304.
• Lump breakers with FLP motor, Mechanical seals and electrical slip ring joint
• Auto Bin Loading mechanism with timer control and Bins.
• Vacuum pump with FLP motor.
• Hot water system (steam heated) with tank and circulation pump.
• Available Capacities 100, 250, 500, 750, 1000, 1500, 2000, 3000 !Us & above.

 

Features:

• GMP construction.
• Jacket fabrication to suit either steam. thermic fluid, hot water media of heating.
• Full vacuum during operation.
• Cones are completely leak proof.
• Loading 8 Unloading with ease.
• Uniform shuffling with more heat surface area.
• Condensers and receivers for solvent collection.
• Custom built models also available far special applications.

 

Product Details:

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.We are a vacuum tray dryer manufacturer and exporter.

 

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%

vacuum tray dryer specification

Product Details:

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.
