Forced Air Evaporator

Forced Air Evaporator Unit is a solution for evaporation of water out of the rejected effluent with friendly environmental way. Generally at Lagoon, only Upper thin layer of water gets natural evaporation. Such quantity is much less as compared to generation of large quantity of effluent. Thus a requirement is felt by the Industry for faster and efficient mechanical solution. We have developed an evaporator unit such that very fine size of water particles are generated and are forced to mix with high volume of Air and are then flown in to the atmosphere to take advantage of evaporation in abundant quantity of atmospheric air.

Fans supplied with the refrigeration equipment are used to cool the air by forcing it past the evaporator coils. These fans are not large enough, nor are they properly located in most cases, to force air directly past the produce. Furthermore, the chilled air leaving the evaporator coils is generally much too cold for most types of produce. It must be mixed with the warmer air inside the room to prevent chill injury. Therefore, additional fans are required to move the air past the produce. To achieve good air distribution, these fans should pull, never blow, the cooled air through the produce as fast as practical.

Features and Benefits: 
  • It decreases the time the produce remains at elevated temperatures, thereby reducing deterioration;
  • It results in shorter cooling times and thus more efficient use of the cooling facility;
  • It can cool produce effectively in a variety of unopened containers without wetting it or subjecting it to excessive handling;
  • It is often more energy efficient than room cooling when large volumes of produce must be cooled;
  • An available room-cooling facility with adequate cooling capacity can be converted to forced-air cooling with only a relatively small investment in fans

Design of Evaporator :

The theory of the evaporator is to mechanically expose more quantum of water mixed with compressed air in to the atmospheric air and to keep that water particles aloft long enough to evaporate them naturally. To achieve this performance we have designed Bipolar nozzles in which Air and water feed simultaneously to produce and send water droplets in to the air for long time to keep them aloft for long distance to evaporate them naturally.

For the same we recommend a pump with pressure of 50 mtrs Head and Air compressor with 6 kg/ pressure. As per general observation, about 60 to 70% of the water spray pump capacity would be evaporated in to the atmosphere on the driest day of the year. Water spray capacity of the pump, about 70% to 80% volume of the same would be maximum evaporated and thus it is estimated that about 70 to 80% of pure water would be evaporated from the sprayed mist.

Actual evaporation capacity will depend on percentage humidity, temperature condition, air wind velocity etc. on a respective day and thus above details are true for estimation only and may vary as per atmospheric condition. To reduce the cost of making Tower we can use you roof top to install the same.
