The Ultrafreeze Tunnel Freezer Process

  • With the UltraFreeze tunnel freezer, you seal in freshness and flavor everytime.
  • This is a great option if you want to quickly and efficiently cool or freeze food.
  • The three basic principles of the Ultra‐Freeze® process are 1) The use of fans to circulate the cold gases at high velocity. 2) Accurate control of temperature. 3) Belt speed control to set required “time exposure”, or “tunnel dwell time” 
  • The UltraFreeze tunnel freezer has a durable fiberglass outer shell that is strong, sleek, realiable, and extremely durable. Perfect for the food processing environment.
  • Ample doors provide complete access and easy entry to the system's interior for cleaning and maintenance. doors are designed to never freeze shut.
  • UltraFreeze tunnel freezer injection system with LN2 or CO2 is automatic and adjustable. Designed with solenoid valves for greater simplicity and higher reliability.

CO2 or Nitrogen, 30" or 48" Wide Conveyor Belt

With the Ultrafreeze Tunnel Freezer Food Processors have an option between using CO2 or Nitrogen gas. There is also an option for 30" wide conveyor belt or 48" wide conveyor belt. The 48" wide conveyor belt has a higher price, but food processors can cover much more surface area if the belt is full of product.



1 Tier VS 3 Tier

Food Processors also have a choice of 1 tier (picture on the right) or 3 tier system (picture on the left). 1 tier sends food product from entry end to exit end, and has a product clearance height of 8.75". 3 tier system sends food product from entry end to exit end, takes a 3" drop, then goes from exit end back to the entry end, then one more 3" drop and back to entry end. This allows food processors to maximize time in the tunnel freezer while utilizing much less floor space. To use 3 tier system, food needs to be able to flip over and have a 3" or less clearance height.
