Our hybrid tunnel pasteurizer is for aluminum cans only and pulls from the design fundamentals of our non-regenerative ‘Tunnel of Love’ and our fully regenerative tunnel pasteurizers. While still maintaining a small, compact footprint this type of tunnel includes regenerative pre-heat and pre-cool zones thereby reducing the glycol cooling requirement by 40%. The hybrid option is a perfect fit for the canning operation that values more efficiency while accepting a slightly larger footprint for any given throughput rate. A key scenario that validates hybrid tunnel integration is a lack of glycol cooling capacity available to meet a non-regenerative tunnel’s requirement or the need to allocate glycol chiller capacity to other processes so not to add additional cooling capacity in the future. 

As the product moves through the tunnel it will travel through 4 stages/zones. They are in order, a regenerative pre-heat zone, heating and holding zone, a regenerative pre-cool zone and finally a cooling zone. The regenerative nature of this design achieves a more gradual product temperature ramp up and cool down and cuts the cooling requirement nearly in half by capturing the cold product temperature of the cans entering the tunnel.
