Abstract
An enzyme bath maintenance system is provided for use in such textile treating fields as stonewashing, laundry, cleaning and dyeing, including the use of enzymes as the active agent, in which the enzymes are utilized within narrowly controlled ranges of pH and temperature. As a means for providing heat for controlling the temperature, a heat exchanger in which the heat source is hot water at a temperature not more than 12 .degree. C. higher than that of the desired temperature, is disposed within the apparatus. The heat exchanger and the apparatus as a whole are designed to avoid pockets which allow the enzyme to become entrapped therein. The apparatus further includes automated means for detecting, monitoring and reporting bath parameters such as pH and temperature, with output for manual or automatic control thereof, and means for agitating the enzyme bath to maintain uniform distribution of the enzyme.
