Excerpt from Prevention of Stream Pollution by Distillery RefuseThe hoffman-a hiers vacuum mash cooker is illustrated by fig. 1. In operation with corn the cooker is about half filled with water (20 gallons of water being used for each bushel of grain to be mashed) and the stirring apparatus, seen within the shell of the cooker on the lef t and actuated by the belt pulley at the end of the machine, is started. Steam is then admit ted, and the grain meal is introduced through the manhole on top. The manhole is then closed and steam forced in until a pressure of about 55 pounds per square inch is reached. To accomplish a thorough digestion, this pressure is maintained about half an hour after the steam is shut off. A vacuum pump connecting at the hell on top of the machine is then started and by reduction in pressure the. Contents of the cooker are cooled down to about 63° C. Ground barley malt mixed with a little water is then added and thoroughly mixed with the contents of the cooker for about half an hour. During this time the diastase of the malt acts upon the starch in the digested grain meal and converts it into maltose and dextri nous matter, the object of the distiller being to increase the maltose and decrease the dextri nous product.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
