Moist Air Extraction

What happens to all the air once it has been through the crop?

Answer:

  1. Traditionally a 1.22 m x 1.22 m cord operated flap or fixed blade louvre was placed at each gable end of the building to vent the air. 
  2. New buildings, however, are well sealed and much more airtight than older buildings so that with the increases in drying capacity and fan sizes consideration needs to be given as to how to remove the air from the building. 
  3. In many instances, cowls are now being employed rather than fixed blade louvres as they have a much higher “free area”. Airspeed through exhaust openings (and intake into the fan house) should be kept below 1000 ft/min.
