Retorts and Tunnel Sterilizers
Pasteurization and Cooling Tunnel
A pasteurisation and cooling tunnel with a working capacity of 3000 L to 18,000 L in SUS304, for packaged dairy, fruit juice and beverage products.
Product Overview
A pasteurisation and cooling tunnel with a working capacity of 3000 L to 18,000 L in SUS304, for packaged dairy, fruit juice and beverage products. It runs four zones: recycled warm water for pre-heating, hot water to pasteurise, warm water to cool and spray the product, then cold water to bring it down. Temperature and holding time are set and controlled automatically, and the procedure can be designed to your product. Standard components include an imported brand chain, JIE or Guomao reducers, UK Spirax Sarco steam regulating and drain valves, SIEMENS PLC and touch screen, and Danfoss or Mitsubishi frequency converters.
Key benefits
Why Buyers Choose This Specification
Water Recycled Between Zones
Warm water recovered from the cooling zones pre-heats the incoming product. That recirculation is where most of the energy saving in a tunnel pasteuriser actually comes from.
Temperature and Holding Time Both Programmable
Pasteurisation units are the product of temperature and time. Setting both under automatic control is what makes the process repeatable and auditable.
Zone Sequence Designed to Your Product
The working procedure is designed according to customer requirements rather than fixed, which matters because a glass bottle and a PET bottle need different thermal ramps.
Named Drive and Control Components
Spirax Sarco valves, SIEMENS PLC and Danfoss or Mitsubishi inverters are specified by name, so spares come from normal industrial supply.
Application scenarios
Where It Is Used
- Pasteurising packaged fruit juice in bottles
- Tunnel pasteurisation of beer in glass or can
- Dairy drinks pasteurised after filling
- Beverages requiring controlled cooling after heat treatment
- Products where thermal shock must be avoided in glass
- Plants needing documented pasteurisation units per pack
Who it is for
The Buyers This Product Suits
Breweries and Juice Bottlers
Tunnel pasteurisation after filling is the standard route to shelf stability for packaged product.
Producers Filling in Glass
The staged warm-then-cold water sequence is what prevents thermal shock breakage in glass containers.
Plants With Energy Targets
Recycled warm water pre-heating is the mechanism that reduces steam demand in a tunnel.
Problems it solves
What It Fixes
Glass Breakage From Thermal Shock
Staged pre-heating and staged cooling using warm water before cold water is exactly what avoids it.
Inconsistent Pasteurisation Units
Temperature and holding time are both set and automatically controlled rather than left to line speed alone.
High Steam Consumption
Recirculating warm water for pre-heating recovers heat that would otherwise go to drain.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
Define the target pasteurisation units for your product before the zone layout is fixed.
Step 2
Confirm container type, since glass requires gentler thermal ramps than PET or can.
Step 3
Size the tunnel against peak line output in litres per hour.
Step 4
Validate the temperature profile with a data logger travelling through the tunnel at commissioning.
Step 5
Plan water treatment for the recirculating circuits to control scaling and biofilm.
Comparison
How It Compares In Our Range
Tunnel pasteurisation against in-line plate pasteurisation.
| Pasteurisation and Cooling Tunnel | Treats product after filling and sealing, so the container is pasteurised too. Essential where post-fill contamination is a risk. |
|---|---|
| Plate Pasteurizer | Treats product before filling, at lower energy per litre, but requires aseptic or clean filling downstream. |
