The working principle of the high temperature tunnel furnace (drying line) is generally to use far infrared to heat the furnace, and then the interior is made of ceramic and stainless steel, so that the infrared light can shine on every corner of the furnace, and then uniformly. Warming up, transferring energy to an object.

The high-temperature tunnel furnace is designed and manufactured with foreign advanced technology, with advanced structure, simple disassembly and assembly, and beautiful appearance. The high-tech thermal insulation material has good thermal insulation performance and strong thermal insulation. The heating technology adopts far-infrared heating technology, the heating element is arranged reasonably, and the power consumption is low. The internal hot air circulation makes the temperature in the oven more uniform, without loopholes, to ensure the quality of the oven products.

Dongguan high temperature tunnel furnace is one of the important equipment in the coating production line, and its temperature uniformity is an important goal to ensure coating quality. The heating methods of the oven are: radiation, hot air circulation and radiant hot air circulation.

The following is an example of the working method of the rotary furnace in the high temperature tunnel furnace:

A rotary furnace is a medium-sized baking equipment that uses a variety of different powers to heat the combustion chamber, and sends hot air into the furnace through a heat exchanger and a fan, and then cooks the food in the furnace.

According to the manufacturer of energy-saving tunnel furnace, because it is heated by hot air, it is also called "hot air rotary furnace". This equipment is suitable for the production of larger quantities of products. Can bake: bread, toast, French sticks, moon cakes, small cakes, wife cakes, egg yolk pie, puffs and all kinds of meat, seafood and other foods. The following is a brief introduction to some of the things that the rotary furnace needs to check before working, mainly divided into the following three points:

1. Confirm whether the power supply of the rotary furnace is normal;

2. Confirm that there is no foreign matter in the rotary furnace.

3. The manufacturer of the energy-saving tunnel furnace stated that it confirmed that the smoke exhaust system of the rotary furnace works normally.

The preliminary work can only be started after the above 3 points have been admitted without error.
