Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an enclosed chamber such as a proofer (fermentation chamber) or an oven (baking chamber) in which a conveyor is installed.

[Conventional technology]

As a typical enclosing chamber having a conveyor inside, a spiral conveyor 1 formed in an endless spiral is installed inside, as shown in Fig. 5 disclosed in Japanese Patent Publication No. 46-27710. There is an enclosed chamber 2. This enclosure chamber 2 is closed by a ceiling surface 3 and a circumferential side surface 4, and has a vast interior space. In this internal space,
There is a spiral conveyor 1 arranged in a plurality of stages in a spiral shape, and an end portion 1a corresponding to the lowest stage of the spiral conveyor 1 is extended to the outside of the surrounding chamber 2 through an opening 5 below the circumferential side 4. On the other hand, the other end 1b corresponding to the top stage of the spiral conveyor 1
The surrounding chamber 2 also passes through the upper opening 6 of the circumferential side 4.
Extended outside. The extensions of these two end portions 1a and 1b of the spiral conveyor 1 are connected outside the surrounding chamber 2 (the connected state is not shown). Therefore, this spiral conveyor 1 is
It can be transported endlessly. Therefore, the spiral conveyor 1 is sequentially fed through the upper opening 6 of the surrounding chamber 2, and moves in a spiral manner from the top to the bottom in the chamber 2.
It is designed to be sent out from an opening 5 below.

When using the envelope chamber 2 configured as described above as an oven (baking chamber) by installing a heating device inside the chamber 2, first place the dough on the spiral conveyor 1 outside the chamber 2. Place the food mold. When this food mold is placed on the conveyor 1 and carried into the surrounding chamber 2, it is baked by the heating device while swirling.

Furthermore, when this enclosure chamber 2 is used as a proofer (fermentation chamber), the temperature inside the proofer is always controlled by installing a heating device, etc., in the same way as the oven described above, so that the temperature is set appropriately. .

[Problem that the invention attempts to solve]

However, the conventional enclosure chamber 2 having the spiral conveyor 1 inside has the following problems.

The internal space closed by the ceiling surface 3 and the peripheral side surface 4 of the surrounding chamber 2 has a vast volume. However, compared to this volume, the volume occupied by the spiral conveyor 1 is small. Therefore, a space unrelated to firing occupies a large volume, and this space is also heated during firing, so the amount of heat for firing is wasted. This causes an increase in running costs. Further, this problem also occurs when the surrounding chamber 2 is used as a proofer (fermentation chamber) as well as when it is used as an oven.

[Means for solving problems]

This idea was made in view of the above circumstances, and was designed to prevent wasted heat from being consumed during baking, fermentation, etc. in an enclosed chamber of an oven, proofer, etc. that has a spiral conveyor inside. In order to prevent this, a tunnel is provided surrounding the spiral conveyor from the entrance to the surrounding chamber to the exit, and one or more partition walls are installed in this tunnel to prevent the spiral conveyor from entering the surrounding chamber. The tunnel is suspended so that it does not come into contact with the transported objects loaded on the tunnel, and a plurality of heat sources are provided on the upper surface and/or lower surface within the tunnel.

[Effect]

Since this invention adopts the above-mentioned specific technical means, it is only necessary to set the inside of the tunnel attached so as to surround the spiral conveyor to a temperature that allows baking or fermentation.
Furthermore, since one or more partition walls are suspended within the tunnel, the temperature of the section partitioned by one partition wall and an adjacent partition wall can be adjusted to some extent.

〔Example〕

This invention will be explained in detail below based on examples.

FIG. 1 shows a perspective view of the entire enclosure chamber according to this invention. The surrounding chamber 2 is closed by a ceiling surface 3 and a peripheral side surface 4, and has a vast interior space. This internal space is provided with a spirally arranged tunnel 7 in multiple stages.
The spiral conveyor 1 is sequentially carried into the tunnel 7 through the opening 6 above the circumferential side 4 of the surrounding chamber 2, and spirally moves inside the tunnel 7 from the top to the bottom to cover the inner circumferential surface of the tunnel 7. The peripheral side surface 4 of the surrounding chamber 2
It is designed to be carried out of the tunnel 7 through an opening 5 below. Although not shown in the figure, this spiral conveyor 1 is connected to the surrounding chamber 2.
Outside, it is connected and endless.

As shown in FIG. 2, the tunnel 7 is turned in a spiral (not shown) inside the surrounding chamber 2, and
They are stacked in tiers. This stacked tunnel 7 is joined with overlapping upper and/or lower tunnels 7. Inside this tunnel 7,
In the upper and lower parts, the burner 8 has a circumferential side surface 4 which is the entrance to the surrounding chamber 2, with its crater 8a facing each other.
from the upper opening 6 (see Figure 1) of the enclosure chamber 2.
It is provided up to an opening 5 (see FIG. 1) below the circumferential side 4, which is an outlet from the inside.

Inside the tunnel 7, as shown in FIG. 3, there is a base 9 with a raised central portion, a support arm 10 that supports the base 9, and a support arm 10 that is rotatably fitted into the lower end of the support arm 10. A spiral conveyor 1 is attached, which includes a bearing 11 and a guide rail 12 that transports the base 9 by rolling both wheels of the bearing 11. A food mold 13 containing dough for bread or the like is loaded on the top surface of the base 9. The food mold 13 is loaded onto the spiral conveyor 1 and conveyed through the tunnel 7.

Inside the tunnel 7, partition walls 14 are further suspended from the upper surface of the tunnel 7 at several locations at appropriate intervals. The partition wall 14 is designed such that it does not touch the upper end of the food mold 13 loaded on the base 9.
Its lower end is set. This partition wall 14
If it is made of a sheet made of polytetrafluoroethylene (trade name: Teflon, manufactured by Du Pont), which is a type of fluororesin, the partition wall 14 will not be damaged even if it comes into contact with the upper end of the food mold 13 during transportation. This is advantageous because it quickly returns to its original position after the food mold 13 has passed. This polytetrafluoroethylene is heat resistant and durable, so once it is installed, it has the advantage that it does not take much time to replace it with a new one due to wear and tear.

As shown in FIGS. 2 and 4, a vast space 15 surrounded by a tunnel 7 is formed in the center of the enclosure chamber 2. As shown in FIGS. Conventionally, this space 15 was also set at a high temperature or a constant temperature in the surrounding chamber 2 for purposes such as baking and fermentation. However, in this idea,
For the above purpose, it is only necessary to set the temperature to a high temperature or a constant temperature inside the tunnel 7, so the space 15 is at room temperature. Then,
If transparent small windows made of heat-resistant glass or the like that can be opened and closed are provided at appropriate intervals on the inner peripheral surface 16 of the tunnel 7, abnormalities within the tunnel 7 (for example,
Even if a load jam, a failure of a spiral conveyor, a failure of a heating device such as a burner, etc. occur, a worker can enter the enclosure chamber 2 through the entrance 17 formed in the ceiling surface 3 of the enclosure chamber 2 and maintain the space. In step 15, repair of a malfunction or the like can be carried out by opening the small window, so that the abnormality can be easily removed.

It goes without saying that the tunnel 7 must be made of a material that can withstand high temperatures. The heating device such as a burner installed in the tunnel 7 is
It is better to divide the inside of the tunnel 7 into several sections so that the switching on and off of the heating device in each section can be managed. This is because, depending on the purpose of use of the enclosure chamber 2, several stages of temperature adjustment may be required when the spiral conveyor 1 conveys dough such as bread. With the above method, several zones with different temperatures are created in the tunnel 7 by turning on and off the heating device. At this time, as described above, if the partition wall 14 is also used, this effect will be further enhanced.

In the above embodiment, a spiral conveyor is used as the conveyor installed in the enclosure chamber, but it is of course applicable to other conveyors. Furthermore, the partition walls suspended inside the tunnel are made of materials other than tetrafluoroethylene, which do not exhibit thermoplasticity.
Any material that is flexible and durable may be used.

[Effect of idea]

As is clear from the above description, the encircling chamber according to the invention is an enclosing chamber that has a conveyor inside, and surrounds the conveyor from the entrance to the enclosing chamber to the exit. A tunnel is attached, one or more partition walls are suspended in the tunnel so as not to come into contact with the objects loaded on the conveyor, and a plurality of heat sources are provided. Since it is provided on the upper surface and/or lower surface within the tunnel, there is no unnecessary heating of the air in the enclosed chamber during baking, fermentation, etc. as in the conventional case. Less heat is consumed. Additionally, in the past, if an abnormality occurred in the enclosed chamber, when the enclosed chamber was used for firing purposes, the heat source had to be turned off and a certain amount of time had passed, and work could not be carried out until the enclosed chamber had sufficiently cooled down. However, in this design, only the inside of the tunnel was heated, and since the tunnel was made of heat insulating material, there was a space at room temperature in the center of the enclosed chamber. It is formed. As a result, people can enter and exit this space,
Even if an abnormality occurs in the enclosed chamber, the abnormality can be quickly removed. Furthermore, since partition walls are suspended inside the tunnel, it is possible to adjust the temperature in the sections separated by the partition walls, allowing for fine-tuned control. As a result, the flavor and aroma of baked bread, etc. are not impaired, and uneven baking does not occur.
