ImmersaFlow™ Batch Retorts

STOCK now offers our patented ImmersaFlow™ retort technology, one of the most promising technologies to be introduced to the in-container food industry in many years. ImmersaFlow™ is a new batch retort process providing precise control of process media fluid dynamics and path of least resistance, resolving the load resistance problem. No more waiting for gravity to work, or the need for increased process utilities to achieve homogenous temperature profiles.

This innovative technology utilizes a closed loop column of process water, channeled through a plenum and closed wall baskets. In essence, ImmersaFlow™ creates an immersion process within the basket. Outside of the basket, the retort shell is primarily empty, minimizing water usage and reducing the amount of heat required for the process.

Efficiency is the key to successful thermal processing and ImmersaFlow™ delivers the solution. By having control of the process media, ImmersaFlow™ has realized 4-6 minute Come Up Times (CUT), with as little as a 2°F spread between the geometric center and permitter of the load. Faster, tighter Come Up Time (CUT) to process temperature allows for more throughput, a more consistent product heating profile, and an overall reduction in energy consumption.

  • Significant reduction in Come Up Time (CUT) to process temperature (ImmersaFlow™ has realized 4-6 minute Come Up Times)
  • Substantially reduces differential temperature between the geometric center and perimeter of the product load with as little as a 2°F spread
  • More consistent heating profile
  • Overall reduction in energy consumption
  • Controls load resistance issues (umbrella effect) by providing precise control of process media fluid dynamics and path of least resistance
