[Industrial applications]

 The present invention relates to a cooking / stirring machine for cooking food such as bean paste while stirring in a pot provided with stirring blades, and more particularly to a cooking / stirring machine for heating with a gas burner.

[0002]

[Prior art]

 For example, when a large amount of kneaded bean paste or kneaded bean paste is produced, a steam-heating type cooking and stirring machine is generally used, and it is produced by boiling and stirring raw bean paste with sugar and water by steam heating. However, steam heating is less likely to cause a fire and safer than combustion heating of gas or the like, but on the other hand, steam heating can usually heat the temperature in the pot up to about 130 ° C. Therefore, when the bean paste is cooked, when the temperature of the sugar added with the bean paste changes to about 150 ° C, it changes to reducing sugar, and the reducing sugar cooks delicious bean paste, but this reducing sugar is not produced. As a result, the taste of the bean paste will drop.

[0003]

[Problems to be solved by the device]

 Therefore, conventionally, a general-purpose simmer that heats with a gas burner, for example, an inner cylinder of heat insulating material is placed inside the furnace main body that has an upper opening and a lower opening, and cooked on the upper opening of the furnace main body. Place the cooker, place the gas burner in the lower part of the insulation inner cylinder, and cook the bean jam using the boiler-cooking stirrer with the vertical stirring blades arranged in the cooker from above. This was also examined, but in this type of cooker / stirrer, the gas burner is located relatively close to the bottom of the cooker in the furnace, and the combustion flame of the gas burner directly hits the bottom of the cooker. There was a problem that it was easy to overheat and burn the bean paste. In addition, since the gas burner is located inside the furnace body, the exhaust gas is likely to remain in the furnace during combustion, and it is difficult for the gas to completely burn, resulting in poor combustion efficiency and increased gas consumption.

The present invention has been made to solve the above problems, and an object thereof is to provide a cooking and stirring machine that can efficiently cook foods such as bean jam without causing a delicious burn. And

[0005]

[Means for Solving the Problems]

 For this purpose, in the cooking and stirring machine of the present invention, horizontal cooking and cooking pots are horizontally arranged with both sides supported by supporting shafts, and a horizontal fire bed surrounds the bottom of the cooking pot at the bottom of the cooking and cooking pot. The stirring blade is attached to the rotating shaft that is rotatably and horizontally inserted in the boiling cooker, and the premixed gas burner that forcibly supplies the combustion air to the side of the fire bed burns. It is characterized in that it is installed so that high-temperature gas is ejected in the horizontal direction in the floor, and that there is a heat ray diffusion convex portion that diffuses heat rays in the fire bed.

[0006]

[Action / effect]

 In the boiling and stirring machine with such a configuration, for example, when cooking bean jam, a predetermined amount of raw bean jam, sugar, and water of the material are put in the boiling cooker, and the gas burner is ignited to cook the bean jam. Is performed. Initially, the stirring blade is driven to rotate at standard speed, and the heat of the gas burner is heated to the maximum. Then, after the temperature inside the kettle reaches a predetermined temperature, the heating power of the gas burner is gradually reduced and cooked up.

During the combustion of the gas, the high temperature gas from the gas burner blows out substantially horizontally into the fire bed and heats the inside of the fire bed, but the bottom of the boiling cooker does not heat directly, so the temperature at the bottom of the cooker is Compared to the conventional cooker that heats the flame of gas directly against the bottom of the kettle, which is much lower than the temperature of the gas burner's flame, it can cook better without burning the bean jam inside the kettle. . In addition, the temperature of the sugar inside the bean paste can be easily raised to about 150 ° C or higher compared to the case where the bean paste is boiled and cooked by steam heating, so the sugar changes to reducing sugar, and this reducing sugar is delicious. You can cook the bean paste.

Further, since the premixed gas burner for forcibly supplying the combustion air is used, the gas can be completely burned even inside the fire bed 4, and the heat ray diffusion convex portion is a high temperature gas inside the fire bed 4. The heating efficiency of the kettle is good because the heat rays generated from the are reflected on the bottom of the kettle.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view including a partial cross section of the boiling and stirring machine, FIG. 2 shows its plan view, and FIG. 3 shows its longitudinal cross section. This boiler / cooker is basically provided with support frames 2 and 3 standing on both sides of a base 1, and a horizontal cooker 5 is mounted between the support frames 2 and 3 via a support shaft 8. It is installed horizontally, and a horizontally elongated fire bed 4 is arranged below the boiling and cooking pot 5 so as to surround the bottom of the boiling and cooking pot 5 horizontally.

The fire bed 4 is formed in a substantially semi-cylindrical shape, and a heat insulating material layered with ceramic fibers is attached to the inside of the outer wall of the fire bed 4 to heat it with a heat insulating material made of ceramic fiber that reflects heat rays with little heat storage effect. It is improving efficiency.

A gas burner 6 is disposed on a side portion of the fire bed 4 so as to face the inner horizontal direction. The gas burner 6 is a premixing type gas burner equipped with a motor-driven blower forcibly supplying combustion air, and ejects high-temperature gas generated by combustion into the fire bed 4. A heat diffusion convex portion 7 made of a heat insulating material is provided at the bottom of the fire bed 4 so as to receive the heat ray of the high temperature gas from the gas burner 6 and diffuse the heat gas upward.

Further, on the upper part of the fire bed 4, a cooking and boiling pot 5 is arranged so that the bottom part thereof can be put in the upper part of the heating bed 4, so that the upper part of the burning floor 4 surrounds the periphery of the cooking pot 5. And a plurality of exhaust pipes 9 are connected to the rear part of the fire bed 4.

The horizontally long cooker 5 is rotatably supported on both sides of the support frames 2 and 3 via support shafts 8 within a certain angle range, and is a lid body located above the cooker 5. The entrance with 5a can be tilted forward. Further, a rotary shaft 10 driven by a motor (not shown) is provided through the center between the support shaft 8 and the boiling cooker 5, and a plurality of stirring blades 11 are provided on the rotating shaft 10 in the boiling cooker 5. Are mounted radially (FIG. 1). Such a horizontal cooker / stirrer, in which the rotary shaft 10 of the boiler / cooker 5, the fire bed 4 and the stirring blades 11 is horizontally arranged, has a smaller installation space than the vertical type and is used in a narrow space. It is possible to

For example, when the bean jam is boiled and cooked in the boiler / cooker 5 of the boiler / stirrer configured as described above, a predetermined amount of raw bean jam, sugar and water of the ingredients are put into the gas burner 6. Ignite and cook the bean jam. Initially, the stirring blade 11 is rotationally driven at a standard speed, and the thermal power of the gas burner 6 is heated to the maximum thermal power. Then, after the temperature in the pot reaches a predetermined temperature, the heating power of the gas burner 6 is gradually reduced to cook the bean jam.

During the combustion of the gas, the high-temperature gas from the gas burner 6 jets out almost horizontally into the fire bed 4 and heats the inside of the fire bed, but the bottom of the boiling and cooking pot 5 is not directly heated. The temperature is about 800 to 900 degrees Celsius, which is lower than the temperature of the flame of the gas burner 6 (about 1600 degrees Celsius), and compared to the conventional cooker that heats the flame of gas directly against the bottom of the pot, It can be cooked satisfactorily without burning. In addition, the temperature of the sugar inside the bean paste can be easily raised to about 150 ° C or higher compared to the case where the bean paste is cooked by steam heating, changing the sugar into reducing sugar and making this reducing sugar a delicious bean paste. It can be cooked.

Further, since the premixed gas burner 6 forcibly supplying the combustion air is used, the gas can be completely combusted even in the fire bed 4, and in the fire bed 4, the gas made of ceramic fiber is used. Since the heat insulating material reflects the heat rays generated from the high temperature gas to the bottom of the kettle, the heating efficiency of the kettle is good.
