HOTFILL SPRAY TANK SYSTEM TESTING SEQUENCE OF OPERATION:

This Hotfill spray tank testing system is designed to provide a controlled method of spraying prefilled and capped containers with a water temperature of approximately 75 degrees Fahrenheit for a specific amount of time in order to test bottle consistency. An operator will prepare and place up to (10) containers onto a perforated stainless steel deck inside the testing chamber. Once loaded, the operator will close the chamber lid and activate the cycle by depressing a cycle start button on the control panel. Once activated, an electromechanical solenoid valve will pressurize the spray manifolds until the preset spray timer has timed out. At this time, the electromechanical solenoid valve will close and a cycle complete pilot light will be illuminated. The tested containers can then be removed from the chamber to be visually inspected as the next step in the process. In the event the main water supply exceeds 80 degrees F, the RTD will signal an electromechanical solenoid ¾" drain valve to open allowing the warm water to vacate the tank. As the level of warm water eventually drops, this will allow the float controls to be opened and allow cold ground water to be re-introduced to the tank supply bringing the water temperature back down to 75 degrees F. Once at the proper temperature, the electromechanical drain valve will close and allow the Telar Heating Unit to maintain water temperature through next cycle If the plant's cold water supply is greater than 75 degrees Fahrenheit, the spray water temperature will be the cold water's temperature +/- 5 degrees F. An internal RTD will display the water temperature being supplied to the spray nozzles.
