Evaporative Cooling/Warming Tunnel

Bevco's Industrial Evaporative Cooling Tunnels are designed to cool hot-filled products in the juice and food processing industries to preserve product quality and package labeling ability. Our Cooling Tunnels use evaporative cooling – the cooling of recirculating water is assisted by circulating a large volume of external airs, taken in and out by the blowers.

Bevco's Warming Tunnels are designed to warm cold-filled products up to a temperature warm enough to prevent condensation on the outside of the package and preserve package labeling ability.

The primary cooling/warming source used is water, which is recirculated within each zone.  No new water is added to the system unless the temperature of the water reservoir differs from the preset temperature threshold.  The outfeed zone is the control zone of the machine; new water is added to this zone as required.

The Warming/Cooling Tunnel can be divided into various zones operating at different temperatures.  For example, a Cooling Tunnel can be designed to cool only, or it can be configured to hold products at a high temperature first for pasteurization before cooling.   In addition, glass bottles can pass through a series of gradual cooling zones to avoid thermal shock.  Each section has hinged stainless steel doors through which machine operation can be observed and product removed.

  • Modular design allows for flexibility in adding or removing sections and ease of shipping and installation
  • Fully automatic water level and temperature controls
  • Custom design to meet your requirements
