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. » Scope Our Spray Dryer Technology has developed a wide range of Spray Dryer Chambers to suit the widest range of material Our Scope of plant range from 5 kg/hr laboratory models to full scale high volume production models in excess of 5000kg/hr and can meet any required industrial manufacturing specification » High Standards We Maintain Customers required whatever the size of plant OR specification, all our plants are designed for higher strengths with high standard than any other spray dryer manufacturer.
Flash Drying is the new kind of drying system used for drying the material such as pastes OR cake state The Word Flash means instantaneous or rapid drying of product, means required short residence time such as few seconds. In Flash dryer the hot air enters tangentially and comes in contact with feed, resulting drying takes place throughout the flash duct removing moisture .This dry material material separated into the high efficiency cyclones or bag filter. Flash dryers are used for drying a wide range of products. » Salient Features • High thermal efficiency. • Low capital equipment cost. • Ideal for high volume through- puts. • Ideal for heat sensitive materials • Ideal for instaneous removal of surface moisture. • Ideal for high drying efficiency and low energy cost. • Consistent product quality with uniform moisture content. • No initial dilution is required and hence direct drying takes place. • Ideal for use in combination with others drying system particularly fluid bed or rotary dryer.
Spin Flash dryer are designed for continuous drying of pastes and filters cakes. The main components of our spin flash dryers are a feed system, the patented drying chambers, and the bag filters. » Feed System This system consist of feed vat and screw feeding system which is used to deliver or feed the material into the spin blow OR drying chamber where the product is buffered and fragmented by an agitator prior to continuous drying. A variable speed is kept of feed screw to control the discharge of feed. » Drying Chamber The rotor of the drying chamber fluidizes product particles in a drying efficient hot air flow patterns in which any wet lumps are rapidly disintegrated. Hot air comes from temperature controlled air heater, entering the drying chambers at a tangent in order to establish a turbulent, whirling air flow. » Bag Filter Powder from the drying chamber is controlled in bag filter while the outlet air leaves the system at the top suction fan. Advantage same as flash dryer. » Material Handling System We have a wide range of equipment and system for handling, conveying, transporting a host of material for various industries Pneumatic Conveying This is the process of conveying /transporting bulk material through a pipe line by either negative or positive pressure air system. The air, when moving with specific velocity, will carry material comes in its path. This system are designed by vast experience, rather than just by formula. Hindustan offers specialize designed system which offers considerable economy. »Basic Components • Piping • Blower/ Fan • Control systems • Rotary feeders • Diverters valves • Ventury / loadings tees • Dust separators (optional)
Rotary dryer are used for to reduce or minimize the moisture content present in the feed. this feed material comes in direct contact with hot gas. This rotary dryer is made up of rotating cylinder number of tube fitted inside. The material which is to be dried enters into the dryer and since the dryer is rotating, the material is lifted up by series of internal fins lining the inner wall of the dryer. After getting high enough, the material falls down back to the bottom of the dryer, passing through the hot gas steam and thus the drying takes place. This dryer can be designed either with co-current OR counter current flow. » Advantages • Simplicity in design. • Sturdy construction. • Can handle wide range of material. • Can handle highest drying temperature. • Possibility of very large through puts. • Adaptability to fluctuating feed rates and moisture contents of product.

Spray drying process is very fast and efficient drying process and which allows a short time for evaporation to takes place and for this it is very essential that the feed can be adequately be atomized into a spray of droplets for successful spray drying. This causes fast drying of the droplets as evaporation occurs from the large surface area is generated by the atomizer. The important factors in the atomization are viscosity, size and surface tension, shape and physical behavior of suspended components which determines how well the feed atomises. Advantages • Highly viscous material can be handled. • Large quantity of material can be handled. • High solids can be handled resulting better economy. • Different wheel types can be designed according to the different material characteristics.
