These are traditional, multi-zone regenerative tunnel pasteurizers designed to reduce or eliminate the need for coolant after pasteurization and accept a wide range of container types from glass containers to plastic, or aluminum cans. An all encompassing, utility-friendly method of tunnel pasteurization. When considering a regenerative tunnel pasteurizer it is important to consider all current and future product and container types, as well as pasteurization unit (PU) requirements for which we will design your tunnel to achieve. 

As the product moves through the tunnel it will travel through multiple stages/zones of heating to achieve then hold pasteurization temperatures, and then cooling to stop pasteurization. The regenerative nature of this design utilizes process water from non-contiguous zones to achieve gradual product temperature ramp up and cool down so to maintain the integrity of the container itself (in particular – glass) while achieving pasteurization targets and improving efficiency.

The holding time and temperature at which the product is pasteurized is often determined by an accredited lab or process authority and assured by the production staff, It is measured in pasteurization units (PU’s) by a data logger, included in our tunnel pasteurizer scope of supply.

Our easy-to-use, touch screen interface allows for efficient observation and manipulation as necessary during this process, and recipes can also be saved for repeated use.
