Thermal treatment
Tunnel pasteurisers, warmers and coolers
Tunnel machines that pasteurise, warm or cool filled containers with precise temperature control and managed energy and water use.
Heat treatment tunnels for any product and capacity
Our heat treatment tunnels are designed to adapt to any type of product — including glass or plastic bottles, jars and cans of all sizes — and to any production capacity.
In-house designed and built control panels allow simple and intuitive management of all process parameters. All panel components are European, guaranteeing worldwide availability.
- Pasteurisation, warming and cooling in one tunnel family
- Automatic over-pasteurisation control
- Glass, PET, jars and cans of all sizes
Installed and commissioned by our team
We size the tunnel on your product, container and PU requirement, then install and commission it with the rest of the line.
Standard machine features
| Construction & frame | Modular frame of micro-bleached AISI 304 stainless steel · removable 2B insulated top and side covers for hot zones · top covers with hydraulic sealing · inspection windows on covers · fully enclosed infeed/outfeed with sliding doors · 1.5° inclined bottom for complete water drainage |
|---|---|
| Drive & conveyor | Polypropylene modular belt on herringbone stainless steel profiles · epicycloidal gear motor with galvanised steel drive shaft and AISI 304 stainless idler shaft · mechanical overload protection (micro-switch) · centralised lubrication on key pins |
| Pneumatics | Group with manual valve, filter assembly, pressure switch and safety valve |
| Over-pasteurisation control | On a prolonged transport stop the system progressively reduces the temperature of the pre-pasteurisation and pasteurisation sections; the belt restarts only when set points are reached. PLC-controlled sequence guaranteeing a maximum over-pasteurisation of 60% |
| Heat recovery on restart | Water from heating and cooling sections is recirculated by pumps; heat exchangers are sized to restore set points in the shortest possible time |
Final specifications depend on product, container and required pasteurisation units (PU).
