Accurate Vacuum Control for High Speed Canning

High speed canning operations depend on accurate vacuum control to provide reliable performance. Vacuum control serves several key purposes:

  • To rapidly draw liquid product into can in very short time frame
  • To minimize splashing from container by minimizing outflow of air
  • To prevent collapse of today’s thinner can walls by avoiding excessive vacuum

Vacuum pumps are used to draw out the air from the can just prior to filling. Depending on the type of pump, the approximate pressure can be set by use of a vacuum breaker, pump speed, or other means. However, as the line speed of the canning line changes, there is a vacuum-control-high-speed-canninglarge change in the required flow rate. Unless a precision, high capacity vacuum regulator is used, these changes in line speed can have a significant effect on the applied can vacuum. These changes can affect fill accuracy, splashing, or (in the extreme situation) collapse of can wall.
The Equilibar® High Flow Vacuum Valve has been successfully used to control canning vacuum and other food packaging vacuum processes. Unlike traditional vacuum breakers, which allow air into the vacuum pump, the Equilibar vacuum valve blocks flow from the vacuum pump. It uses an unusually large diaphragm area to facilitate lightning-fast response to changes in vacuum pressure. Because the larger diaphragm valve is dome-loaded, the desired vacuum set-point can be communicated from either a manual set-point regulator or an electro-pneumatic set-point regulator.
