The INDIRECT GAS HEATED TUNNEL has unique flexibility and the ability to produce a variety of products. The oven is based on a concept, each zone has two Weishaupt gases.The burner heats the air and distributes it to the top and bottom of the oven through a heat exchanger.The use of separate burners at the top and bottom can provide the best temperature control and fast response time. Compared with the traditional single burner oven, it has more flexibility.
Each oven area is composed of flexible modules that are easy to transport and fast to install. If you need more capacity, you can add other areas.
As with all tunnel ovens, indirect gas ovens consist of carefully selected components that are designed to be continuous and very energy efficient.
FEATURES AND BENEFITS of INDIRECT GAS HEATED TUNNEL
INDIRECT GAS HEATING
The ovens are divided into a number of heat zones where each zone can be separately regulated for top and bottom heat.
In ovens equipped with a steam system the first part of the oven contains steam spread boxes made out of the highest grade of stainless steel. Valves with indicators are used to adjust the proper flow of steam.Possibility to add photocell controlled and/or volume of steam/h system.
For some products, especially when baking in tin cans, the air circulation and radiation of the turbo fan should be combined.Turbo zones allows for the baking time to be reduced, lower temperatures used and more equal colouring.
OVEN CONTROL SYSTEM
The PLC Touchscreen is designed to be easy to use and give the best possible overview and control.
The tunnel ovens are manufactured in two basic versions, depending on the desired temperature range: Normal temperature up to 275°C (530°F)* and as option high temperature up to 340°C (645°F)* in first zone bottom heat.
BELT DRIVING SYSTEM
The frequency converter controls the speed of the drive motor, and the sturdy belt drive system provides the best reliability and accurate baking time. Long ovens and ovens for heavy products are equipped with dual drive systems, each with its own motor.
