Can Thermal Exhaust Tunnel

Detailed Equipment Introduction

Gain in-depth insights into Can Thermal Exhaust Tunnel equipment’s working principles, application scenarios, and technical highlights.

Can Thermal Exhaust Tunnel

This thermal exhaust tunnel heats open or loosely closed cans before final sealing. Steam heating raises the temperature of the contents and supports air exhausting as part of the canning process. The tunnel is intended to connect with timed downstream sealing operations.

Key Features

Thermal air exhausting for unsealed or loosely closed containers.
Heating takes place inside an exhaust chamber over a selected residence time.
Uses saturated steam and thermal expansion of the can contents as part of the exhausting process.
Intended for coordination with final sealing while the contents remain heated.
Listed handling capacity of 300–500 cans/min, with a listed container diameter range of 50–270 mm.

Applications

Canned food containers
Tinplate cans
Aluminum cans
Glass bottles
Plastic bottles

Frequently Asked Questions

Are cans sealed before entering the exhaust tunnel?

The tunnel is described for unsealed or loosely closed containers. Final sealing is coordinated with the heating and exhausting step.

How does the tunnel perform thermal exhausting?

The chamber uses saturated steam to heat the containers and contents over a selected time. Heating and expansion support exhausting before the containers are finally sealed.

How are the heating conditions selected?

The heating profile and residence time are selected for the food, container and downstream sealing process. Product-specific thermal processing requirements also need to be defined when integrating the tunnel into a canning line.
