Tunnel Pasteurizers for the Craft Beverage Industry
A tunnel pasteurizes the product after it is filled and sealed, so you get shelf-stable cans and bottles without changing how it tastes. Canadian built, 25 to 300+ containers per minute, installed and serviced by Juicing Systems.

Overview
A tunnel pasteurizer heats your filled, sealed containers to a target, holds them to hit your pasteurization units (PUs), then cools them back down. Producers add this step when they move from taproom or local sales into retail and distribution: anything with fermentable sugar or live cultures can keep working in the package and cause re-fermentation or a failed can on a shelf you do not control. Because the product is treated inside the sealed package, there is no path for post-fill recontamination. Jenrey builds three tunnel families covering cans, PET, and glass, from 25 up to 300+ containers per minute.
Key takeaways
Pasteurizing after the fill is the kill step most producers add when they move from taproom or local sales into retail distribution.
It is designed to protect product character; you and your process authority set the temperature and PU target, not the machine.
Cans, PET, and bag run on the non-regenerative and hybrid tunnels; glass needs the fully regenerative TANK.
A tunnel does not have to match your full line speed, which can lower the capital cost.
Three designs, one decision
Which Jenrey tunnel fits how you run?
Jenrey builds three tunnel families. The right one depends on your containers, your run lengths, your utilities, and your floor.
How to choose
Start with glass. If you run glass now or expect to, you need the TANK; it is the only design that pasteurizes glass safely. If you run cans (and PET or bag), want the lowest running cost over time, and your floor can take a slightly larger machine, the Hybrid is the most efficient choice. If you run cans and your priorities are the tightest footprint, the lowest upfront cost, or frequent changeovers, the Tunnel of Love is the simplest fit and keeps running through stop-start days. When you are between two, it usually comes down to one question first (do you need glass, which requires the TANK) and then floor space versus running cost (which decides Hybrid against Tunnel of Love). Send us your containers, run lengths, and floor space and we will confirm the fit.
Tunnel of Love vs Hybrid vs TANK
| Tunnel of Love | Hybrid | TANK | |
|---|---|---|---|
| Thermal recovery | None | Moderate (about 40% less heating and cooling demand) | Maximum |
| Containers | Cans, PET, bag | Cans, PET, bag | Cans, glass, plastic |
| Throughput | 25 to 300 cpm | 25 to 300 cpm | 25 to 400 upm, PU dependent |
| Footprint | Most compact | Tunnel of Love + about 8 ft | Largest |
| Capital cost | Lowest | Mid | Highest |
| Cost of ownership | Higher | Lowest | Low (when balanced) |
| Stop-start tolerance | Excellent | Prefers steady runs | Continuous production |
| Glass | No | No | Yes |
Tunnel of Love models
Throughput and PU figures below are based on 355 mL (12 oz) cans. Other container sizes shift both, so your container mix is specified before the build.
| Model | Throughput | Body | Base PU | PU upgrades |
|---|---|---|---|---|
| TOL25 | 25 cpm | Narrow (21″ chain) | 50 PU | up to 120 PU |
| TOL50 | 50 cpm | Narrow (21″ chain) | 50 PU | up to 120 PU |
| TOL100 | 100 cpm | Wide (48″ chain) | 60 PU | 200 or 400 PU |
| TOL150 | 150 cpm | Wide (48″ chain) | 60 PU | 200 or 400 PU |
| TOL200 | 200 cpm | Wide (48″ chain) | 60 PU | 200 or 400 PU |
| TOL250 | 250 cpm | Wide (48″ chain) | 60 PU | 170 or 250 PU |
| TOL300 | 300 cpm | Wide (48″ chain) | 60 PU | up to 120 PU |
On the TOL25 and TOL50, higher PU targets are reached with a wider chain. On the 48 inch wide-body models (TOL100 and up), higher PU adds tunnel length at the same throughput.
Does the tunnel have to match my line speed?
No, and this is where a lot of buyers save money. If only part of your production needs pasteurizing, a smaller tunnel running at a fraction of your line speed gets you shelf stability at a lower capital cost. When you run product that does not need pasteurizing, the same machine runs as a warmer, reducing condensation from cold-filled cans before labeling and packing. One machine, two jobs, sized to what you actually pasteurize instead of what your filler can theoretically do. That is the first thing we work out with you before a quote.

How does a tunnel pasteurizer work?
Filled, sealed containers enter on the infeed conveyor. They pass through a heating and hold zone that brings the product up to temperature and holds it against your PU target, then through a cooling zone that brings it back down to stop the process. Temperature, time, and PU delivery are logged on every run. A typical cycle runs the product up from your fill temperature to around 60 C and back down, though the exact set points are yours to set for your product and PU target.
Will a tunnel change how my product tastes?
This is the first thing most producers ask, whatever they make, and it is the right question. A tunnel is built around controlled, gradual temperature changes rather than a hard thermal shock. You set the entry temperature, the hold, and the target PUs to your product, so the process is tuned to what you make, not forced on it. Jenrey describes its tunnels as designed to preserve flavour and product integrity while delivering consistent, repeatable results.
Any thermal step interacts with your specific product, so we validate your PU target with your process authority and dial the tunnel to it before a quote.
Canadian built, locally backed
Jenrey Ltd designs and manufactures every tunnel in-house in Burlington, Ontario. Their tunnels are running in everything from craft cideries with custom-fit units squeezed into small warehouses up to full production build-outs. That build quality is the reason we put our name next to theirs.
Juicing Systems is Jenrey’s representative across Western Canada and the Western US. We handle sizing, layout, quoting, financing, installation, training, and service. Jenrey handles fabrication, controls, and commissioning. You get one local point of contact and the factory behind it.
Buy the tunnel you need now, not the one you might need in five years
Jenrey offers a buyback on previously supplied tunnels, credited toward a new, larger unit. Start with the tunnel that fits today’s volume and today’s building. When production outgrows it, trade up, including across designs, say from a Tunnel of Love to a regenerative TANK in a new facility.
Around the tunnel
Warming tunnels (condensation removal for cans, better label adhesion)
Cooling tunnels (rapid uniform cool-down after hot filling)
Keg equipment (semi-automatic through fully automatic keg lines)
Boilers (steam and hot water packages)
Need inline pasteurization before the fill instead of after it? We also carry flash (HTST), hot-fill, and UV pasteurizers.
Frequently asked questions
What is the difference between batch and tunnel pasteurization?
Both treat product after filling. A bath or chamber pasteurizer processes containers in batches and suits lower volumes. A tunnel runs continuously inline with your packaging line, processing 25 to 300+ containers per minute with logged PU validation as they go. If you are packaging more than a few hundred cases a day, a tunnel usually wins on labour and consistency.
Will pasteurizing change my product?
The process is tuned to your product; you set the entry temperature, hold, and target PUs with your process authority, and the tunnel uses controlled, gradual temperature changes rather than a hard shock. Jenrey designs its tunnels to preserve flavour and product integrity. Any thermal step interacts with your specific product, so validate your PU target with your process authority or an accredited lab.
How many PUs do I need?
That depends on your product, and it is a decision for you and your process authority, not your equipment vendor. If you do not have a requirement yet, we point you to accredited third-party labs. We then build the tunnel to hit it, with data logging to prove it.
Can I pasteurize glass bottles?
Yes, on the fully regenerative TANK. Its gentler temperature transitions protect glass integrity. The non-regenerative and hybrid tunnels run cans, PET, and bag, not glass.
What utilities do I need?
Heating (low-pressure steam, gas-fired hot water, or electric on the smallest models), glycol cooling, plant water, compressed air, and drainage. We review your existing boiler and glycol capacity during sizing, and Jenrey supplies boiler packages where needed.
What does a tunnel pasteurizer cost?
It scales with throughput, PU target, and configuration. Tell us your line speed, containers, and product and we prepare a tailored proposal. Financing and leasing are available through a partner lender, subject to approval.
Who installs and commissions it?
Juicing Systems installs, trains, and services the tunnel in our territory. Jenrey fabricates the tunnel, programs the controls, and supports commissioning, with a scope document so nothing falls between the cracks. Installation, training, and support are available as services.
What is the lead time?
Typically 12 to 16 weeks from order, though it varies with the order book and any custom departures from standard designs. Ask for the current schedule when you request a quote.
