Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roasting machine for roasting, for example, peanuts, bean confectionery, etc., and in particular, a roasting machine provided by sieving a dough body to roast the confectionery body. Regarding the improvement of the roaster.

[0002]

2. Description of the Related Art For example, as a method of roasting peanuts, bean confectionery, etc., firstly, a dough body is directly roasted by a combustion flame of gas, and secondly, it is indirectly roasted by hot air. The method of making is generally used conventionally. First
The concrete structure of the roasting machine according to the method is that the container body is supported in the main body of the roaster so as to be horizontally swingable, and a pair of upper and lower gas burners with the container body interposed therebetween are provided in the main body. − Are arranged to face each other. Then, by rocking the container horizontally, the gas bar
It is provided so as to be directly roasted by the combustion flame of the knife. Further, as a specific structure of the roasting machine according to the second method, hot air is blown into the roasting machine main body, and the dough is stirred by the hot air and indirectly roasted.

[0003]

However, in the roasting machine which is provided so that the container body is horizontally rocked and directly cooked by the combustion flame of gas as described above, the heat efficiency is poor and the surface is In addition to the tendency of charring to occur in the part, it takes a long time to roast, that is, the heat of combustion in the roasting machine passes through the container body to roast the dough body and then escape to the outside of the roasting machine as it is. As a matter of course, good heat efficiency cannot be obtained because of the heat, and when roasting using the heat of combustion of gas, heat is gradually transferred from the surface part of the dough body to the center part. The surface part is heated and dried first, but in addition to the problem that the surface part is easily burnt by heating and drying from the surface part first, On the need to prevent charring Of INaru temperature is relatively low temperature (17
The roasting time is long (10 kilograms of peanuts are roasted) due to the fact that the water content in the central part is hard to escape by being heated and dried from the surface part first, and the roasting time is long (10 kg of peanuts is roasted). However, there is a problem in that it causes a problem of about 20 to 25 minutes). Further, in a roasting machine provided so as to indirectly stir by stirring with hot air, there is a problem in that the fibrous material of the dough body is decomposed by the stirring action of hot air. The present invention is an attempt to improve the above-mentioned problems in order to solve the problems, and the object of the present invention is to improve the thermal efficiency of the roaster and perform roasting in a short time without burning the surface portion. At the same time, it is possible to obtain a confectionery that is uniform and has a glossy surface without decomposing the fibrous material. That is, the present invention is provided so as to stir through radiant heat of hot air and far infrared ceramics,
It can be roasted in a short time without causing charring on the surface part, and by blowing hot air to the rocking dough body through the straightening plate, the fibrous material can be uniformly and glossy without being decomposed. It is characterized in that a certain finish can be obtained, and its concrete means and action are as follows.

[0004]

[Means for Solving the Problems] A container body for inserting a dough body is horizontally swingably provided in a main body, and a large number of vent holes are formed in a lower position of the container body and coated with far-infrared radiation ceramics. And a plurality of heating pipes coated with far-infrared radiation ceramic are extended horizontally in the upper position of the container body, and are horizontally crossed at regular intervals. A hot air generator with a built-in gas burner is installed, and a blower is connected to the rear of the hot air generator, while a suction duct is extended from the exhaust port that opens to the top wall of the main unit. To the blower.

[0005]

When the combustion flame of the gas burner is blown as hot air into the main body by the blower, the hot air is evenly dispersed by the straightening plate. By uniformly distributing the hot air in this way, the dough body is shaken horizontally without fluctuating and is roasted, and the uniformly dispersed hot air heats and drys the dough body evenly from the surface. The effect of causing is obtained. On the other hand, far infrared rays are radiated from the far infrared ray radiating ceramics of the rectifying plate and the heating pipe which are heated by hot air, and the permeation action of the far infrared rays has the effect of heating and drying the dough body from the inside. That is, the dough can be roasted from both inside and outside at the same time. Further, the suction duct that connects the exhaust port of the main body and the blower provides the function of circulating hot air, and the effective use of the heat of gas combustion can be measured. That is, the energy saving effect can be enhanced.
