Industrial Dryers

Product Details:

The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Based on the configuration, rotary dryers can be classified as co-current, counter current, direct fired and indirect fired. Explanation of each configuration is given below:

Other Details:

• Function and principle of operation Spin Flash dryers are designed for continuous drying of cohesive and non-cohesive pastes and filter cakes, as well as high-viscosity liquids
• The main components in a complete Spin Flash Drying System are a feed system, drying chamber, bag filler and Exhaust Blower
• The feed system consists of a feed vat where a discontinuous flow of product is buffered and fragmented by an agitator prior to continuous drying
• A variable speed feed screw (or pump in the case of fluid feed) forwards the product to the drying chamber
• Drying chamber The disintegrate at the base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated
• Hot air is supplied by a temperature-controlled air heater and speed-controlled fan, entering the drying chamber at a tangent in order to establish a turbulent, whirling air flow
• Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering
• The drying chamber is rigidly designed to withstand pressure shock in the event of explosive combustion of flammable particles
• All bearings are effectively protected against dust and heat
• Bag filter Powder from the drying chamber is collected in a bag filler, while the outlet air leaves the system at the top via a suction fan

Rotary Vacuum Dryer offer clean, simple and effective method of drying wet cake, powder, and even slurry. Labor and energy costs are minimal compared to tray dryers and product losses during handling are also negligible. Additionally, valuable organic solvents can be conveniently condensed and recovered.

Working Principle:
The drying in a rotary vacuum dryer is a batch operation under vacuum. It is possible to dry heat sensitive materials at well below boiling points of water and solvents. Drying time depends on the material being dried, amount of solvent or water to be removed, desired final moisture content, permissible jacket temperature etc. The dryer is available in sizes ranging from 100 liters to 20,000 liters gross volume. The volume of wet material loaded into the dryer is usually restricted to 40-45% of gross volume.

Features:

• Equipped with different designs of agitators depending on the material to be dried.
• Unique quick opening discharge valve permits direct packing of dry product into bags or drums
• Breaker rods are provided to prevent lump formation and allow quick and complete drying
• Shaft sealing by mechanical seals is also available
• N2 pulse jet dust filter (self-cleaning type)

Product Details:

In Fluidized Bed Dryer, the process air is supplied to the bed through a special perforated distributor plate and flows through the bed of solids at a velocity sufficient to support the weight of particles in a fluidized state. Bubbles form and collapse within the fluidized bed of material, promoting intense particle movement. In this state, the solids behave like a free-flowing boiling liquid.

• Advanced method of drying wet/semi-wet solids
• Unlike in Tray Drying every solid particle is floating of Air which is blown from down to up creating material layer in fluidized state
• Almost every wet particle directly receives the heat energy from hot Air resulting in uniform and quick drying.
