[0004]

In the conventional bread dough processing machine, since the processing air is blown out to the lower part of the storage case 1 and is sucked in at the upper part, the air flow in the storage case 1 is It always rises from the bottom to the top. However, when low temperature air is supplied into the storage case 1, the specific gravity of the air is large, so the rising speed of the air becomes slow. For this reason, the low-temperature air tends to stagnate in the lower part of the storage case 1, and the temperature of the upper part in the storage case 1 tends to rise when the low-temperature air is supplied. Further, when the hot air is supplied into the storage case 1, the specific gravity of the air is small, so that the rising speed of the air becomes faster. For this reason, the hot air tends to concentrate on the upper part of the bread dough storage case 1, and the temperature of the lower part of the storage case 1 tends to decrease when the high temperature air is supplied. As a result, there is a problem in that the bread dough cannot be uniformly processed due to the temperature unevenness, and the quality of the produced bread varies.

The present invention has been made in view of the above problems, and an object of the present invention is to make the temperature distribution in the bread dough container always uniform regardless of whether low temperature air is supplied or high temperature air is supplied. An object is to provide a bread dough processing machine capable of processing.

[0006]

In order to achieve the above object, the present invention provides, in claim 1, a bread dough storage box having a plurality of bread dough loading shelves arranged in the vertical direction. In a dough processing machine that selectively supplies low temperature air for cooling the dough and high temperature air for heating the dough,

There is provided switching means for inflowing the low-temperature air from the upper end of the air passage and for injecting the high-temperature air from the lower end of the air passage when supplying the high-temperature air into the storage.

Further, according to a second aspect of the present invention, a bread dough storage box having a plurality of sheaves for placing bread dough vertically arranged is provided, and low temperature air for cooling the dough and high temperature air for heating the bread dough are selected in the storage box. In the dough processing machine which is supplied in a single manner, it has a large number of air blowout holes facing one side surface direction in the bread dough storage, and the opening area above the air blowout holes is formed larger than the opening area below. The first ventilation passage and the second ventilation passage having an air outlet facing the lower part of one side of the bread dough storage in the lateral direction and having the generation portion for the high temperature air therein are provided, and the generation portion for the low temperature air is provided. Are arranged on the air intake side of each ventilation passage.

[0008]

According to the bread dough processor of the present invention, when the low temperature air is supplied into the bread dough container, the low temperature air flows in from the upper end of the ventilation passage and flows in the ventilation passage from the upper side to the lower side. .. As a result, a large amount of low-temperature air is blown out from the upper air outlets and a small amount is blown from the lower air outlets, and the low-temperature air tends to stagnate at the bottom of the bread dough storage. Becomes uniform. When hot air is supplied to the bread dough storage, the hot air flows in from the lower end of the ventilation passage and flows in the ventilation passage from the lower side to the upper side. As a result, a large amount of high temperature air is blown out from the lower air outlets and a small amount is blown out from the upper air outlets, and it is easy for hot air to concentrate on the upper portion of the bread dough storage. Becomes uniform.

Further, according to the bread dough processor of claim 2, when the low temperature air is supplied into the bread dough container, the generated low temperature air flows into each of the first and second ventilation passages. At this time, since the air opening holes of the first ventilation passage are formed so that the opening area of the upper side is larger than the opening area of the lower side, a large amount of air has flowed into the first ventilation path from the air blowing holes on the upper side and the lower side. Blow less from the air blowout holes of. Also, the second
The air that has flowed into the ventilation passage blows out from the air outlet to the bottom of the bread dough storage. As a result, the temperature distribution in the bread dough container becomes uniform even when low temperature air is easily supplied to the lower portion of the bread dough container. Further, when the hot air is supplied into the bread dough container, the hot air is generated only in the second ventilation passage, and the hot air is blown from the air outlet in the second ventilation passage to the lower portion of the bread dough container. Also,
Air having a temperature lower than that of the high-temperature air is blown from each of the air blowing holes in the first ventilation passage, and the air is supplied at the same temperature as when the low-temperature air is supplied.
A large amount of air is blown out from the upper air blowing holes, and a small amount is blown from the lower air blowing holes. As a result, the temperature distribution in the bread dough storage is uniform even when the hot air is easily supplied to the upper portion of the bread dough storage.

In addition, the air in the first ventilation passage 17a is not heated, and in a state where the temperature is lower than the air in the second ventilation passage 18a, more air is blown out from the upper air ejection hole 17b and less air is blown out from the lower air ejection hole 17b.

As described above, according to the bread dough processing machine of the present embodiment, during the freezing mode operation in which the low temperature air is likely to stay in the lower part of the storage case 1, the upper part of the storage case 1 is higher than the lower part. Since the air is actively blown out toward the
The temperature distribution inside can be made uniform. Further, during the fermentation mode operation in which high temperature air is likely to concentrate in the upper part of the storage case 1, the high temperature air heated by the electric heater 12 is blown to the lower part of the storage case 1 and the high temperature air is discharged. Since the air having a lower temperature than that is blown to the upper part of the storage case 1, the temperature distribution in the storage case 1 can be made uniform as in the case of supplying the low temperature air.

[0026]
