2. Description of the Related Art Heretofore, a dough processing machine of this type shown in FIG. 5 has been known.

In this bread dough processor, a plurality of bread dough loading shelves 2 are vertically arranged in a heat insulating bread dough storage cabinet 1, and a humidifying unit 3 is provided below the lowest shelf 2.
And a machine room 6 for accommodating the compressor 4, the condenser 5, and the like of the refrigeration circuit is provided above the bread dough storage box 1. An air passage 7 is provided in the bread dough storage 1, and an evaporator 8, a blower 9 and an electric heater 10 are arranged in the air passage 7. Further, the bread dough is molded into a predetermined shape, and the molded bread dough A is arranged in the tray 11 and stored in each shelf 2.

In this bread dough processor, a refrigerating mode operation for supplying air (about -18 ° C.) cooled by the refrigerating circuit and the air cooled by the refrigerating circuit are heated and dehumidified by the electric heater 10. A refrigerating mode operation for supplying as air (about 10 to 15 ° C) and a fermentation mode operation for adding moisture to the air (about 25 to 40 ° C) heated by the electric heater 10 by the humidifying unit 3 are performed in stages. Switch. As a result, the processing steps proceed in the order of freezing (storage) → thawing → refrigeration (aging) → fermentation, and the bread is completed by taking out the fermented bread dough A and baking it in an oven (not shown).

[0005]

However, in the conventional bread dough processing machine, since the processing air is circulated in the vertical direction, the processing air is distributed to the bread dough A located in the lateral center of each shelf 2. There was a problem that the bread was not sufficiently supplied and the finish of the bread varied.

The present invention has been made in view of the above problems, and an object thereof is to provide a bread dough processing machine capable of uniformly supplying processing air to the bread dough placed on each shelf. Especially.

[0007]

In order to achieve the above-mentioned object, the present invention comprises a bread dough container having a plurality of bread dough placing shelves arranged vertically, and a predetermined temperature and a predetermined temperature are stored in the container. In a bread dough processing machine for supplying air for bread dough processing adjusted to humidity, a blowout dough processing air outlet is provided on one side of the storage, and a bread dough processing air suction port is provided on the other side of the storage. And at least one air storage chamber partitioned by a partition plate facing the side surface of each shelf is provided between the air outlet and each shelf, and the air storage chambers are evenly arranged on the partition plate. A plurality of air outlets are provided.

[0008]

According to the bread dough processor of the present invention, the dough processing air is blown out from one side of the bread dough storage chamber and is sucked into the other side of the bread dough storage chamber. It is distributed along the bread dough placement surface of each shelf and is evenly supplied to the bread dough. At this time, the bread dough processing air discharged from the air outlet is made uniform in flow rate and flow velocity with respect to the side surface of each shelf in the process of flowing from the air storage chamber to the bread dough storage portion side through the air blowing holes.

Here, the operation of the bread dough processor of this embodiment will be described.

First, the molded dough A is placed in the tray 23.
When they are arranged in the storage box and stored in the storage box 20 and the automatic operation is started, each mode operation of freezing, refrigerating, and fermentation described below is sequentially performed.

In the freezing mode, the freezing circuit operates to cool the inside of the storage box 20 to about -18 ° C, and the bread dough A is stored frozen.

Next, after a lapse of a predetermined time from the start of the refrigerating mode operation, the operation shifts to the refrigerating mode operation. In this refrigeration mode, the operation of the refrigeration circuit is continued,
The electric heaters 33 and 34 are driven to heat the cooling air,
The temperature inside the storage 20 is raised to about 10 to 15 ° C. As a result, the dough A is thawed and aged for several hours in a refrigerated state.

When the refrigerating mode operation is completed, the fermentation mode operation is started. In this fermentation mode, the operation of the refrigeration circuit is stopped and each electric heater 33, 34 and the humidifier 38 are driven. As a result, the high temperature (2
The air of high humidity (about 5 to 40 ° C.) is supplied, and the dough A is fermented.

When the fermentation mode operation is completed, the bread dough A is taken out of the storage box 20 and baked in an oven (not shown) to complete the bread.

In each of the above operations, the ventilation passage 25
The processing air that has flowed into the first air storage chamber 30 from the inside is made uniform in flow rate and flow velocity with respect to the back surface of the storage case 20 in the process of flowing from the air outlet hole 28a to the second air storage chamber 31. The air is blown out from the air outlet 29a toward the bread dough container. As a result, the treated air is evenly distributed between the shelves 22, and then collected in the ventilation passage 25 and circulated in the storage box 20.

As described above, according to the bread dough processor of the present embodiment, the processing air is circulated laterally from the back side of each shelf 22, and the first and second air storage chambers are provided on the processing air outlet side. Since the processing air is blown out through the air storage chambers 30 and 31 and the air outlets 28a and 29a, the processing air can be evenly distributed between the shelves 22. The processing of each bread dough A can be performed evenly. Further, since the vertical direction of the storage case 20 can be reduced by making the flow direction of the treated air horizontal, the installation space can be reduced by placing an oven or the like on the storage case 20. You can also plan.

In the above embodiment, the two air storage chambers 3
Although 0 and 31 are provided, only one air storage chamber may be provided.

[0021]

As described above, according to the bread dough processing machine of the present invention, the dough processing air can be evenly distributed between the shelves, so that the processing of each bread dough can be performed uniformly. ..
