“Leak Detect Flush Time Delay”
position
The Flow Diversion Device will move into the “Leak
Detect” position once the legal pasteurization tempera-
ture is achieved. The time of the clearance is controlled
by a Flow Diversion Device Controller which is a sepa-
rate device.
In this position the common body between the “Divert
Valve” and the “Leak Detect Valve” is purged and the
milk is routed back to the balance tank out of the leak
detection port of the “Leak Detect Valve”. This return
line to the balance tank has to be separated from the
return line of the “Divert Valve”.
In the “Leak Detect” position the “Divert Valve” is in
the activated position. The “Leak Detect Valve” is in the
closed position which is detected by the sensor in the
control module.
The “Flow Diversion Device” will stay in the “Leak
Detect” position until the Flow Diversion Device Con-
troller sends out the signal to transition to the “Forward
Flow” position.
“Forward Flow” position
The “Forward Flow” position enables the pasteurized
product to flow through the “Leak Detect” Valve to the
heat holder and subsequent sections of the pasteurizer.
In the “Forward Flow” position both valves are in the
activated position.
