The air injector controls operation of a dump valve to inject air into the milkline for more effective washing. In addition an air purge system can be controlled to evacuate fluid in the milkline at appropriate times. Automatic air purge has two main advantages: 1. Valuable milk remaining in the line is flushed into the tank prior to washing, rather than going down the drain. 2. During washing cold water from the previous cycle is flushed out to avoid cool-down of the next wash. The front panel has lights to show which action is currently operating. Direct Buy A$795 |
