Air Dispersion Dryers :

We offer a wide assortment of air dispersion dryers that are used for drying applications of wet cakes, pastes, sludges and production of powders from aqueous suspension. Due to the dewatering mechanism, these dryers provide effective solutions and converted to either filter cakes, pastes or sludges. These air dispersion dryers are chosen on the basis of wet deed cake particle size distribution of final powder and drying curve. Our range of air dispersion dryers includes spray dryers, rotary dryers, flash dryers, spin flash dryers, vibrated fluid bed dryers and fluid bed dryer. Features: Smooth functionality Easy operation Durable performance See More-

Rotary Dryers :

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: Unique Features Efficient drying of materials with high moisture contents. Handles a wide size range of materials with extended residence times. Design permits highest possible drying temperatures. Drying, cooling or calcination. High thermal efficiency. Application Co-Current Applications : Wet feed in contact with the hottest drying gases supplied from an external source, where heat transfer is by convection.

Spray Drying Plant:

Spray Drying Systems Manufacturer: We have designed spray drying plants that is also based on single stage operation and extensively used to convert solutions, suspensions and slurries into dry powder within a few seconds without any intermediate handling. These dryers are suitable for drying heat sensitive materials due to the rapid speed and proper temperature. Further, these are also provided with rotary atomizer, a pressure nozzle or a two fluid nozzle to ensure effective atomization. Features: Easy to handle Highly effective Superior functionality Spray Dryer method OR process is the most economic method OR process of evaporation to convert liquid feed OR slurry having specific percentage of solids to solid powder particles. Still powder is one of the most cost effective in both storage & transportation of finished goods. We provide turnkey projects of Spray Dryer for MCCP, Microcrystalline Cellulose Powder, Zinc Sulphate Powder, Sulphur WDG Powder, Herbal Extract.

Rotary Atomizer:

A coating applicator is disclosed which includes a rotary atomizer on a driven shaft. The shaft operates at high speeds. Coating material is supplied to the rotary atomizer. A pair of spaced bearings rotatably mount the shaft and a seal assembly is positioned between the rotary atomizer and the front bearing. The seal assembly includes a bearing cover having a cutting edge. A mating cap member surrounds the shaft and has a sealing shoulder which is engaged by the cutting edge. Exhaust air is used to cool the bearings, pressure the interior of the applicator and enhance the seal assembly. The formation of sprays having the required droplet size distribution is vital to any successful spray dryer operation so that powder specifications can be met. Atomization is a high technology area where We has played a central role in the development and use of various nozzles and rotary atomizers in spray drying. We has mastered the manufacturing of atomizers for almost all products viz. dyestuff, dairy products, pharmaceuticals, food products, optical whiteners, ceramics, detergents, etc.. The choice of atomizer depends upon the properties of the feed and the dried product specification. In cases where more than one atomizer type is suitable, the rotary atomizer is generally preferred due to its greater flexibility and ease of operation and handling of high feed rates without need for atomizer identical arrangemnets handling of abrasive feeds, no blockage problems, low pressure feed system,ease of droplet size control through wheel speed adjustment,optimization of particle size of dried material

Spray Dryer:

Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying medium; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used.[1] All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disk and single-fluid high pressure swirl nozzles. Atomizer wheels are known to provide broader particle size distribution, but both methods allow for consistent distribution of particle size.[2] Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process needs, drop sizes from 10 to 500 µm can be achieved with the appropriate choices. The most common applications are in the 100 to 200 µm diameter range. The dry powder is often free-flowing. The most common type of spray dryers are called single effect. There is a single source of drying air at the top of the chamber (see n°4 on the diagram). In most cases the air is blown in the same direction as the sprayed liquid (co-current). A fine powder is produced, but it can have poor flow and produce a lot of dust. To overcome the dust and poor flow of the powder, a new generation of spray dryers called multiple effect spray dryers have been produced. Instead of drying the liquid in one stage, drying is done through two steps: the first at the top (as per single effect) and the second with an integrated static bed at the bottom of the chamber. The bed provides a humid environment which causes smaller particles to clump, producing more uniform particle sizes, usually within the range of 100 to 300 µm. These powders are free-flowing due to the larger particle size. The fine powders generated by the first stage drying can be recycled in continuous flow either at the top of the chamber (around the sprayed liquid) or at the bottom, inside the integrated fluidized bed. The drying of the powder can be finalized on an external vibrating fluidized bed. The hot drying gas can be passed in as a co-current, same direction as sprayed liquid atomizer, or counter-current, where the hot air flows against the flow from the atomizer. With co-current flow, particles spend less time in the system and the particle separator (typically a cyclone device). With counter-current flow, particles spend more time in the system and is usually paired with a fluidized bed system. Co-current flow generally allows the system to operate more efficiently.
