Abstract THE MASH IS HEATED TO A PREDETERMINED TEMPERATURE WHICH SHOULD BE MAINTAINED UNIFORMLY THROUGHOUT THE MASH WHILE IT PASSES THROUGH A HOLDING ZONE WHERE ENZYMATIC REACTIONS TAKE PLACE. FOR THIS PURPOSE, THE HEATED MASH IN THE HOLDING ZONE IS CAUSED TO FLOW THROUGH A CHANNEL HAVING AN ELONGATED CROSS-SECTIONAL AREA AND WHICH DIRECTS THE FLOW IN A HELICAL PATH AROUND A HORIZONTAL AXIS.
