[Prior art]

 Conventionally, in a factory that mass-produces food, when it is finally dried to a desired moisture content or steamed into a product, a heating device for drying is provided in front of the final process. Also equipped with a steamer.

For example, in the case of producing raw noodles or semi-raw noodles, there is a noodle-making machine equipped with a heating device in order to maintain the water content of the produced noodles at an appropriate value.

As the heating device Y, as shown in FIG. 4, a heating device Y is generally arranged in the middle of the conveying device X such as a conveyor for conveying the noodles N near the final step of noodle making.

The heating device Y has a heating space Z which also serves as a noodle-conveying space inside, and a long box 51 having a steam-type heating pipe 50 is arranged along the noodle-conveying direction. The noodles N are dried by flowing steam into the heating pipe 50 to heat the heating space Z to a desired water content. The use of steam as a heat source is due to cost reasons.

The heating pipe 50 is embedded in the ceiling wall 51a and the floor wall 51b of the box 51 so as to face each other, and each is formed in a meandering shape.

The steam inlet 50a and the steam outlet 50b are provided at one end of each of the heating pipes 50, 50 arranged on the ceiling wall 51a and the floor wall 51b, respectively, so that steam can flow.

With the above configuration, while being transported by the noodle transporting device X, the noodles are heated while being passed through the heating space Z 1 of the heating device Y and dried to a predetermined water content.

In FIG. 4, reference numeral 52 is a noodle transfer means such as a net, 53 is a frame of the transfer device X, and 54 is a conveyor drive means such as a motor.

[0010]

[Problems to be solved by the device]

 However, the above heating device Y still has the following problems.

That is, since a large number of heating pipes 50 for allowing steam serving as a heat source to flow in are embedded in the ceiling and floor walls 51a and 51b of the box 51, the heat efficiency is poor and the noodles have a desired moisture content. In order to dry up to this point, it is necessary to lengthen the heating space Z to be heated, which complicates the layout in the factory and requires a large amount of steam, resulting in a high cost.

An object of the present invention is to provide a food heating device that can solve the above problems.

【Example】

 1 is an explanatory view of a food heating device according to the present invention, FIG. 2 is a side view of a spiral heating pipe included in the heating device, and FIG. 3 is a front view thereof. Will be described below with reference to the drawings as a heating device for making noodles have an appropriate water content.

In FIG. 1, A is an automatic noodle making machine, and shows the line of the final step thereof.

The heating device 1 provided in the automatic noodle making machine A has a conveyor device 2 for conveying the noodles M, a heating pipe 3 wound in a spiral shape, and steam flowing in the hollow portion of the pipe 3. A steam type heating pipe 3 capable of generating heat is provided.

The heating device 1 is framed by a frame F, and the conveyor device 2 installed in the frame F is wound around a rotating roller 5 provided with an endless net 4 as a noodle transporting means as a rotating means. It is configured by turning.

The conveying speed of the conveyor device 2 can be adjusted so that the noodles M placed on the endless net 4 can be conveyed at an arbitrary speed. m is a drive motor that drives the rotary roller 5, and 6 is a transmission chain that connects the drive motor m and the rotary roller 5.

In place of the endless net 4, for example, a conveyor device is configured with a pair of chains arranged in parallel, a rod-shaped object is hung between the chains, and noodles M are hung on the chain to be conveyed. You can also

The heating pipe 3 formed in a spiral shape has a food heating space Q for heating and drying the noodles M therein, and the endless net 4 is passed through the space Q to make the noodles. The noodles M are heated and dried while they are passed through the food heating space Q.

In addition, a long pipe cover 7 is arranged so as to surround the spiral heating pipe 3.

Furthermore, a pump P is attached to the upper part of the outer periphery of the pipe cover 7 to suck the heated air in the food heating space Q, and to direct the heated air from the starting end 3a of the spiral heating pipe 3 to the above. The heated air can be discharged to the side of the noodles that is in the conveying direction, and the heated air is discharged toward the noodles M that are being heated and are not yet heated.

That is, the heated air transfer pipe 8 is connected to the pump P that sucks and discharges the heated air in the food heating space Q, and the heated air outlet port 8 a that opens at the end of the pipe 8 is formed into the spiral shape. It is provided on the upper side of the starting end 3a of the heating pipe 3 and at a position communicating with the inside of the pipe cover 7 so that the noodles M conveyed in the pipe cover 7 are initially heated.

The pipe cover 7 is composed of upper and lower covers 7a and 7b, each of which is a cylinder divided in half in the longitudinal direction, and a surface carry-in port 14 and a surface carry-out port 15 are formed at both ends of the pipe cover 7, respectively. At the same time, a hanging rubber 16 is attached to each of the same-surface carry-in port 14 and the surface carry-out port 15 to prevent heated air from flowing out to the outside as much as possible.

Here, the heating pipe 3 formed in a spiral shape will be further described. As shown in FIGS. 2 and 3, the heating pipe 3 in this embodiment has an installation length of about 3 m. A steam outlet 11 and a steam inlet 12 are formed at the start end 3a and the end 3b, respectively. Steam is circulated in the hollow portion of the pipe.

Since the high-temperature steam flows through the heating pipe 3, the pipe 3 itself generates heat and the food heating space Q can be sufficiently heated by its radiant heat, but is formed in a spiral shape. Therefore, the distance over which steam flows is substantially longer than the arrangement length.

Therefore, the noodles M transported in the food heating space Q can be efficiently dried to a desired water content while being transported in the space Q.

At this time, the dried state can be appropriately adjusted by adjusting the conveying speed of the noodle M and changing the time for the noodle M to pass through the food heating space Q.

In FIGS. 2 and 3, reference numeral 13 is a mounting member for mounting the spiral heating pipe 3 on the inner peripheral surface of the pipe cover 7.

Next, a case where the noodles M are actually dried will be described below with reference to FIG.

The noodles M placed on the endless net 4 are carried into the pipe cover 7 from the noodle carry-in port 14 of the pipe cover 7, and firstly, are discharged from the heated air blowing port 8 a of the heated air carrying pipe 8. Initially heated by the heated air sucked from the food heating space Q.

Therefore, the noodles M are not rapidly heated and the surface thereof is not cracked, but can be entirely dried to the inside by the subsequent heating in the food heating space Q, and the quality of the product can be improved. Can be improved.

The heated air is slightly cooled while passing through the heated air carrying pipe 8.

Subsequently, the noodles M are transported into the food heating space Q formed inside the heating pipe 3 formed into a spiral shape, and while passing through the food heating space Q, they are dried to a desired water content. To be done.

At this time, in order to obtain a desired water content, the time for the noodles M to pass through the food heating space Q may be adjusted, and for that purpose, the transportation of the noodles M by the conveyor device 2 is performed in advance. Just set the speed.

Further, the food heating space Q is in a sufficiently high temperature state due to the steam that fills and flows into the hollow portion of the heating pipe 3. In addition, since the pipe through which the steam flows has a spiral shape, the heat efficiency by radiant heat is high, and the length of the spirally formed heating pipe 3 in the longitudinal direction may be about 40% of the conventional length.

Therefore, the drying time of the noodle M can be significantly shortened as compared with the conventional case, and the work efficiency can be improved.

Further, since the thermal efficiency is improved, the fuel consumption is good and the fuel can be saved.

Furthermore, since the heating device 1 can be constructed compactly, the degree of freedom of layout in a factory or the like is increased, and the manufacturing cost of the device can be suppressed.

The noodles M that have passed through the food heating space Q and dried to a desired water content are further carried out from the noodle carry-out port 15 of the pipe cover 7, packed in a bag by an operator in the final step, and then put into a product. Will be shipped.

By the way, although the production of the noodles M has been described in the present embodiment, the present invention is not limited to the noodles M but can be applied to a wide range of other foods.

Further, by using the food heating device 1 according to the present invention, it can also be used as a steamer.

That is, the inside of the pipe cover 7 may be kept in a high-humidity atmosphere, and the pipe cover 7 can be used, for example, for manufacturing dumplings, buns, and the like. Further, even when the food itself contains a large amount of water, it can be in a steamed state.
