Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cracker baking apparatus, and is particularly applicable to the production of various rice crackers under different heating conditions.

[0002]

2. Description of the Related Art Conventionally, as a baking apparatus of this kind, a rice cracker dough placed on a conveyor running endlessly in a baking furnace of a small heating chamber is heated and baked by upper and lower burners. The cooling during was simply due to the outside air.

Further, the combustion of the burner is to burn with the air that naturally flows into the small heating chamber, and naturally there is a limit to the heat insulation treatment of the small heating chamber. In addition, in order to cool the outside air and use it effectively, the heat insulating process or the like cannot be performed on the entire device, and the exhaust heat from the burner combustion is exhausted to the outside of the factory. Conventionally, this exhaust heat is exhausted outside the factory by a ventilation fan mounted on the ceiling of the factory. However, with this level of exhaust, the factory is hot even in winter.

[0004]

By the way, in such a rice cracker baking apparatus, the burner blocks of the preheating section and the coloring section are separated from each other, while the burner block of the floating section is formed by one casing. Therefore, it is difficult to control the temperature. For example, it was very difficult to bake a normal rice cracker made from non-glutinous rice and a hail made from glutinous rice in the same baking apparatus.

[0005]

As a result of studies in view of the above, the present invention has developed a product which can produce rice crackers and sardines with a single baking apparatus.

That is, the present invention relates to a rice cracker baking apparatus in which a large number of burners are installed above and below a mesh wire mesh belt conveyor on which rice cake dough is placed, and the burner is provided for each small heating chamber covered with a heat insulating material by a blower. Combustion air is forcedly blown to increase the burning rate of the burner, while cold air whose free temperature is set by an air conditioner etc. is heated to a small heating chamber by a blower. During the process, the rice cracker dough is cooled on a mesh wire mesh belt conveyor, and this operation is repeated in sequence.Furthermore, the heat from the burner is exhausted from the exhaust heat control damper at the upper part of the small heating chamber by the exhaust fan at the upper part of the exhaust duct. It is a rice cracker baking device characterized by being forcedly exhausted.

[0007] In a rice cracker baking apparatus in which a large number of burners are installed above and below a mesh wire mesh belt conveyor on which rice cracker dough is placed, a preheating section, a floating section, a core removing section and coloring are sequentially performed in the moving direction of the mesh wire mesh belt conveyor. The burner combustion air is forcibly blown into each heat insulation small heating chamber covered with each heat insulating material by a blower to increase the burn rate of the burner and set a free temperature by an air conditioner or the like. While moving the rice cracker dough heated in the small heating chamber by the blower to the next small heating chamber, cool the rice cracker dough on the mesh wire mesh belt conveyor, repeat this operation in sequence, and then heat from the burner. Is a baking apparatus for rice crackers, which is forcibly discharged by an exhaust fan located above an exhaust duct from an exhaust heat control damper located above the small heating chamber. The blower that blows the burner combustion air should have a speed change function. The same applies to a blower that sends cold air.

The rice cracker baking apparatus is characterized in that an adjusting damper is provided on the upper surface and / or side surface / or bottom surface of the heat insulating small heating chamber. In addition, the preheating part exhaust duct, the floating part exhaust duct, the core exhaust part duct, and the coloring part exhaust are controlled by the upper exhaust heat control damper of the exhaust pipe of the heat insulation small heating chamber of each part of the preheating part, the floating part, the core removing part and the coloring part. This is a baking device for rice crackers, which is characterized in that each duct is provided individually. The above-mentioned one was a relatively large exhaust duct, but it is characterized by using ducts for each process. In the present invention, the heat generated by the burner or the surplus heat can be reused as another heat source by using a heat exchanger or the like provided outdoors (inside) through the exhaust duct.

As described above, by installing a plurality of adiabatic small heating chambers continuously in all parts of the firing apparatus and providing an exhaust heat control damper in each adiabatic small heating chamber, the temperature inside the adiabatic small heating chamber is adjusted. Became easier. A humidifying device may be provided in the heat insulation small heating chamber. And as such a humidifying device, a steam outlet or a water spray nozzle is suitable. This is because arare etc. have the effect of improving the gloss of the surface of the baked product by heating while giving appropriate humidity in the preheating stage. By giving it, fine cracks can be generated on the surface and the commercial value can be increased. It should be noted that this sprinkling nozzle is preferably capable of spraying water in a mist form.

In the present invention, the floating portion also has a plurality of adiabatic small heating chambers connected in series. In the production of hail made from glutinous rice, in the case of hail dough made from glutinous rice, the dough that started to float was cooled once during the process of floating (expansion) after preheating due to the characteristics of glutinous rice. This is because it has been found that by giving another floating effect, it is heated to the inside and fully floated. In the case of rice crackers made of non-glutinous rice, the floating part is not usually cooled.

Further, the core removing part is for removing cores in the dough completely by heating for a long time for the cores which are not sufficiently cored in the floating part with respect to arachis and especially thick rice crackers. is there.
