Description

Far infrared sweet potato oven

technical field

The utility model relates to a roasting equipment, in particular to a far-infrared sweet potato oven.

Background technique

Roasted sweet potatoes are one of the foods that Chinese people like more. The World Health Organization (WHO) also recommends sweet potatoes to all human beings as a vegetable and fruit food with high health value. In August 2007, the Ministry of Education analyzed and evaluated snacks for teenagers. Among the hundreds of commonly used foods for teenagers, roasted sweet potatoes and milk ranked first, and were rated as "snacks that can be eaten every day, which are beneficial and harmless." Most of the traditional ovens are simple in design, simple in production, low in thermal efficiency, wasteful, poor in sanitation, serious in pollution, labor-intensive and time-consuming, and difficult to control. They use briquettes and coke, which produce a large amount of harmful gases such as sulfides after combustion, accompanied by certain nuclear Radiation, long-term use will cause great harm to the human body, and there are still a large number of ovens converted from chemical raw material barrels on the market, which will cause greater harm to human health.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is a structural representation of the utility model;

Detailed ways

As shown in Figure 1: including furnace body 20, curved surface ceramic cylinder body 3, refractory material 2, asbestos layer 5, hemp rope 6, dustproof heat preservation cover 19, upper cover 9, bracket 15, fuel container 14, guardrail 10, base 12. Universal wheel 13. The inner and outer layers of the curved surface ceramic cylinder 3 are made of high-temperature resistant materials. The smooth curved surface is conducive to the accumulation of heat radiation and minimizes the loss of heat energy in the furnace. The innermost layer of the refractory material 2 is coated with nanometer Infrared powder 1, nanometer far-infrared powder 1 has the effect of converting heat radiation into far-infrared rays, and the temperature distribution in the furnace is relatively uniform. According to actual measurements, only about 1.5Kgs of charcoal is needed to bake a furnace of about 15Kgs of sweet potatoes, which is more than traditional ovens. Save more than 2 times energy.

Nano far-infrared powder 1 inner surface is provided with fixed support 15, several layers of annular support 15 are close to interior furnace wall, and support 15 is provided with annular food tray 21, and annular tray 21 is the semi-garden-shaped stainless steel bar, can increase and decrease layer and distance between layers.

The outer outer layer of refractory material 4 is wrapped with asbestos cloth 5 or thermal insulation cotton, and the outermost layer of asbestos cloth 5 or thermal insulation cotton is wrapped with hemp rope 6 made of natural plant material, which not only has the function of fixing the asbestos layer 5, but also has the effect of being beautiful and preventing accidental burns , the upper part of the curved surface ceramic cylinder 6 is provided with a small hole, the temperature detection rod 16 is connected with the steel pipe 18, and the temperature control meter 17 is placed above the side of the furnace body 20. When the temperature in the furnace exceeds the set range, the buzzer will alarm and remind The operator takes measures to raise and lower the temperature. Even if the temperature control meter 17 fails or the operator forgets to turn off the heat source or is unattended, due to the special structure of the furnace body 20 and the strength of the materials used, it can also ensure that the fire source will not burn out of the furnace, so The safety performance is high. Because the temperature in the furnace is relatively uniform and the product is far away from the flame, the heat of the product is mainly from hot air convection and far-infrared rays, so the heat is relatively uniform, and there is less burnt skin or uneven raw and cooked, and the taste is excellent.

The periphery of the top of the furnace body 20 is made of stainless steel plate, and several air outlet holes 8 are arranged on the periphery to facilitate air convection or release of water vapor in the furnace. A sheath 7 is arranged next to the top of the furnace body 20. Body 20 loam cake 9, guarantee product sanitation, and described loam cake 9 is basin type, and edge is level, and central part is recessed, and the product that has baked can be stored therein and also can play warming effect.

The fuel container 14 is placed on the bottom of the body of furnace, and the fuel container 14 is positioned on the base 12. The fuel container 14 is provided with upper and lower layers. Furnace body 20 plays a fixed role, and an air inlet is arranged on the suspended side in the middle of guardrail 10, and the door corresponds to air inlet 11 of guardrail 10, and air inlet 11 can be opened or closed arbitrarily, and the opening or closing of the air inlet valve can affect the oxygen supply amount, thereby affecting the size of the flame or the convective intensity of the hot air.

The central part of the guardrail 10 is the fuel container 14 of the heat release source, which is designed to be movable, and can take out and clean up the charcoal as required or directly remove it from the intake valve.

The following of the guardrail 10 is welded as one with the square base 12, and 4 universal wheels 13 are adorned below the base 12, which is convenient for short-distance movement.
