Question
i have already put this question to many experts on this site but no to the point reply.If you can please, the question is:
a)How much air (cubic feet/ton of barley)is to be pressed in the germination box.
b)How much air (cubic feet/ton of green malt)is to be passed through in the kiln section for drying of green malt.

Answer
Germination,or house fans-push or pull large volumes of humidified,attemperated air through the germinating grain at 6.3-10 CFM/BU.

Total drying time in a kiln is 36 hrs.,during which the moisture content is lowered from 48% to 4.0% Hot air is passed through the bed of malt in huge volumes.The floor is perforated to allow hot air to pass through the bed of malt.Variable combinations of air flow and heat are introduced,as the temp,and air flow varies on malt being made.Ranges of air flow can be as low as 10CFM to higher than 30CFM/BU
