Well, with a batch machine being a single chamber process, meaning that the wash, rinse, and dry are all done in the same chamber, there is a little bit of loss with the chemistry after each cycle. At the end of the wash cycle there will be some chemistry on the walls of the chamber, on the rack itself, and on the boards that will get washed away after the first rinse. It’s a very small amount and it is part of the process. You could get excess loss through the exhaust on the machine if it’s set too high. As the machine is running and it is being atomized and sprayed in the chamber, the exhaust can draw it out of the chamber, and it is lost. Also, if you have a transfer valve or mixing valve that could be hung up, it could be draining out that way as well. However, it is mostly exhausts set too high and then it would be one of the valves that are hung open.
