Energy-saving far-infrared hot drying oven

Abstract

The invention provides an energy-saving far-infrared hot drying oven. The energy-saving far-infrared hot drying oven structurally comprises an oven body provided with a conveying belt, wherein a plurality of carbon fiber far-infrared heating tubes are arranged in the oven body; the carbon fiber far-infrared heating tubes are arranged at the periphery of the conveying belt; exhaust outlets are formed in the top of the oven body; a control box connected with the carbon fiber far-infrared heating tubes is arranged at the outer side edge of the oven body; the carbon contents of the carbon fiber far-infrared heating tubes are at least 99.7 percent of carbon fibers; and the carbon fiber far-infrared heating tubes are formed by decomposition, extrusion and forming at the temperature of 350 to 450DEG C and carbonization treatment at high temperature of 1500 to 2500DEG C. According to the energy-saving far-infrared hot drying oven disclosed by the invention, the characteristic that the wavelengths of the carbon fiber far-infrared heating tubes are longer is fully utilized, baked objects are directly heated up in a radiation way, and radiation energy absorbed by the objects is transmitted to particles such as atoms and molecules in the objects, so that the particles generate irregular movement, the heating function of the objects is caused, and the energy-saving far-infrared hot drying oven realizes the effects of high efficiency and energy conservation; and the energy-saving far-infrared hot drying oven is simple in structure and is convenient in maintenance.

Description

Technical field: [0001] 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: [0002] There are mainly two types of traditional oven structures. The first 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. Heating; the second type of structure is to directly heat the inside of the oven through oil or natural gas by installing various fuel oil equipment or gas equipment inside the main body of the oven. [0003] 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 objects to be baked inside the oven main body are heated through the circulation channel during oper...

AI Technical Summary

Problems solved by technology

The traditional heating technology is heating from the outside to the inside, and the inside can only be transferred to the inside when the temperature reaches a certain level. During the heat transfer process, the temperature near the inner wall of the oven is high, while the temperature in the middle is low, resulting in insufficient heating inside the main body of the oven. Uniform, the heat absorbed by the object to be baked is easy to lose, resulting in low utilization rate of the heat absorbed by the object to be baked, the degree of dryness is inconsistent, the time required for baking is too long, and the energy loss is too high
