INDIRECT GAS HEATED TUNNEL OVEN
The indirect fired gas tunnel oven offers a unique flexibility and capability for producing a wide variety of products. The tunnel oven is built on a concept where each zone has two gas burners heating the air and distributing it to the top and the bottom of the oven through heat exchangers. Using separate burners for top and bottom provides individual temperature settings for top- and bottom heat and by that optimal temperature control and fast reaction time, giving more flexibility compared to a traditional singel burner oven. Indirect gas (oil) heated ovens can be used up to 230°C. Available belt width is 1.5 m * Up to certain length.
By using separate burners for top and bottom heat the oven becomes more easy to regulate and the oven also reacts much faster.
Each zone in the tunnel oven is controlled independently of each other since the temperature is set in each zone.
To receive the lowest possible energy consumption in an indirect gas heated tunnel oven use multi burner system for heating (one burner for top-heat and one for bottom heat, in each zone).
A traditional oven cannot be run if the burner goes out, with our oven its still possible to produce since we use multiple burners. This makes the oven very reliable.
There is a finally cooling section has included at the end of roasting levels against the product coming out of the tunnel hot and absorbing the moisture in the air.
It can be arranged with feeding shaker at input and cross collecting shaker at output by request.
