Spray Drier
Product Description
There are two basic types of atomization :
Spray Drier Configuration :
Advantages Of Using A Spray Dryer For Drying Application :
Spray Dryer:
Spray drying is the transformation of feed from a fluid state into a dried form by spraying the feed into a hot drying medium. The feed is pumped from the product feed tank to the atomizing device, located in the air disperser at the top of the drying chamber. The drying air is drawn from the atmosphere via a filter by a supply fan and is passed through the air heater to the air disperser. The atomized droplets meet the hot air and the evaporation takes place, while cooling of the air happen simultaneously. In Spray Drier, after the spray is dried in the drying chamber, the majority of the dried product falls to the bottom of the chamber and enters to a pneumatic conveying and cooling system.
The fines, which are the particles with a small diameter, will remain in the air, and it is therefore necessary to pass the air through cyclones to separate the fines. The fines leave the cyclone at the bottom via a locking device and enter the pneumatic system, too. The air passes from the cyclone to the atmosphere via the exhaust fan. The two fractions of powder are collected in the pneumatic system for conveying and cooling and are passed through a cyclone for separation, after which they are bagged off. The instrumentation comprises indication of the temperature of the inlet and outlet air, as well as automatic control of the inlet temperature by altering the steam pressure, amount of oil or gas to the air heater, and automatic control of the outlet temperature by altering the amount of feed pumped to the atomizing device.

There are two basic types of atomization :
- Nozzle atomizer
- Disc atomizer
Spray Drier Configuration :
- Co-Current Flow
- Counter Current Flow
Advantages Of Using A Spray Dryer For Drying Application :
- Control of particle size. Spray dryers can typically produce between 30 to 500 micron average particle sizes, in a bell shaped distribution.
- The shape of most spray dried particles is spherical, which provides for fluid-like flow properties.
- Spray drying produces the most homogeneous product.
- Many heat sensitive products can be spray dried easily at relatively high inlet temperatures.
- Permits drying without thermal degradation.
Multiple Effect Evaporators:
Evaporators are thermal concentrators for concentrating dilute liquid for increasing the solids content and for reducing volume of evaporating liquid, widely used for the concentration of liquids in the form of solutions, suspensions and emulsions.

| Vapour | Separator | Vapour | Calandria | Vapour | Condensate |

Multiple Effect Evaporator (MEE) :
In Multiple Effect Evaporators (MEE), there is a conservation of heat as steam from the boiler is used for the first effect and then the vapour generated from the product is used as the heat source in the second effect. The vapour generated here is then used as the heat source in the third effect and finally heats water for some other process or preheats the incoming feed.
Multiple Effect Evaporator - Effluent Treatment :
Evaporators are used to convert entire quantity of effluent to zero liquid discharge by separating water and salt using evaporation and separation technology by concentrating the effluent to the saturation level and subsequent separation of salt and water through centrifuging and drying.
Industries like Textile Dying, Pharmaceutical & Drug Industries, Pulp mills etc. during the manufacturing process generates huge quantity of high toxic effluents which has high BOD, COD, TS and TDS level with black coloured and odour effluent. To overcome all the environmental problems, Zero Liquid Discharge Effluent System is required depending upon the type of effluent for evaporation and drying.
