Description

Energy-saving infrared heating oven

Technical field:

The invention relates to a processing device, in particular to an energy-saving far-infrared heating oven used in the technical field of baking and heating.

Background technique:

There are mainly two types of traditional oven structures. One structure is to install various electric heating tubes inside the main body of the oven. The electric heating tubes are stainless steel electric heating tubes, ceramic infrared electric heating tubes or quartz electric heating tubes. After powering on, the oven is directly heated. The second structure is to directly heat the inside of the oven through oil or natural gas by installing various fuel oil or gas equipment inside the oven main body.

But no matter which of the above-mentioned ovens is used, the main body of the oven needs to be equipped with an air duct sealing plate and circulating air, and the to-be-baked object inside the main body of the oven is heated through the circulation channel during operation. In the process of heat transfer, the temperature close to the inner wall of the oven is high, while the temperature in the middle is low, resulting in uneven heating inside the main body of the oven, and the heat absorbed by the baked object is easily lost, resulting in a low utilization rate of the heat absorbed by the baked object and dryness. The degree is inconsistent, the time required for baking is too long, and the resulting energy loss is too high.

Invention content:

In view of the shortcomings of the above-mentioned background technology, the present invention provides an infrared heating oven that can heat the inside of the working box uniformly, has a fast heating rate, achieves a baking effect, and has a remarkable energy-saving effect.

In order to achieve the above technical problems, the present invention provides an energy-saving infrared heating oven, the structure of which includes a box with a conveyor belt in the middle, and a plurality of infrared rays that can directly heat up the baked goods by using infrared radiation are installed inside the box. The generating device, the infrared generating device surrounds the conveyor belt, and the box body is provided with an air outlet and a control box connected with the infrared generating device on the side.

The infrared generating device is a carbon fiber far-infrared heating tube. A further measure is: the carbon fiber far-infrared heating tube has a carbon content of at least 99.7% carbon fiber, which is decomposed and extruded at 350 ° C and then used at 1500 ° C - 2500 ° C ℃ high temperature carbonization treatment. The carbon fiber far-infrared heating tube has the characteristics of strong penetrating power and small thermal inertia. It does not need air duct sealing plate and circulating air, and is suitable for all kinds of baked goods.

According to the needs of actual baking, the box can be a rectangular open structure or a rectangular sealed structure; the infrared generator is installed on the upper and lower sides or left and right sides of the box; the conveyor belt is a flat conveyor belt or a suspended conveyor belt.

The air exhaust port is opened on the top of the box body; the control box is installed and fixed on the outer side of the box body.

In addition, aluminum silicate wool for improving the heat preservation effect can also be sandwiched inside the side wall of the box body.

Because there is an infrared generating device that can directly heat the object to be baked by using infrared radiation in the operating box, after power on, the infrared generating device uses infrared radiation to directly dissipate heat to the object to be baked in the box, because it is directly heated. The object to be baked is heated without air as a medium, and the heat transfer is fast, and the heat energy is directly diffused to the object to be baked without being absorbed by the intermediate substance, so as to achieve the purpose of energy saving; and because it belongs to the overall heating, the place where infrared rays radiate, the uniformity of temperature rise Well, it is not affected by the presence or absence of air, that is, the temperature is uniform, there is no heating blind area, and there is no temperature difference. Compared with the traditional oven, the present invention saves energy consumption by at least 40%, increases the required process baking time by at least 50%, has remarkable effect, and has high cleanliness and no dust.

Simple structure and easy maintenance.
