Abstract
Green malt is withered in a stream of humidified air heated to a temperature not greater than 60.degree. C. and thereafter dried in a stream of air at a temperature of up to 85.degree. C. to produce pale malt, in apparatus including a drying kiln, a temperature sensor in the outlet stream of air from said kiln, and a valve operable by the temperature sensor to recycle at least part of said outlet stream of air from said kiln to the air inlet of said kiln.
Claims6
In a process for the preparation of pale malt comprising the steps of steeping corn and subsequently germinating said corn to produce green malt and thereafter kiln-drying said green malt to produce pale malt, said kiln drying including the steps of withering said green malt by passing a first inlet air stream at a temperature of up to 60.degree. C. through said green malt for a time sufficient to wither said malt, whereby a first exhaust air stream containing moist air issues from said malt during said withering;
- and passing a second inlet air stream through said malt after said withering at a temperature of up to 85.degree. C. for a time sufficient to dry the malt, the improvement comprising humidifying the air for said first inlet air stream.
