In the first embodiment of the present invention, the second steam ejection pipe 15 is located in the lower part of the first conveyor 7. In this aspect, the lower part of the steam storage 1 is heated and the lower part is heated. It is possible to continue cooking in

As for the steam supplied from the second steam injection pipe 15, the steam actually brought into contact with the noodle strings as in the case of the first steam injection pipe 11 is steam of about 100 ° C. and high in dryness. preferable. For this reason, since the temperature of the steam supplied from the injection pipe can be lowered, the steam temperature in the steam injection pipe is set to 100 ° C. or higher superheated steam (about 100 ° C. to 120 ° C., preferably about 103 ° C. to 115 ° C.). It is suitable.

In the first embodiment of the present invention, the second steam injection pipe 15 is mainly used for imparting steam to the noodle strings being conveyed at the lower stage of the first conveyor 7. That is, the noodle strings M carried in from the inlet 3 of the steamhouse 1 pass through the first and second stages, and the noodle strings being transported to the outlet side in the third stage can be steamed. A steam injection pipe 15 is disposed at the lower part of the first conveyor.
Of course, the steam supplied by the first steam injection pipe 11 and the second steam injection pipe 15 contributes to the steaming of the noodle strings group throughout the steam storage 1.

─The first steam injection pipe and the second steam injection pipe are separate systems─
In the first embodiment of the present invention, a mode is shown in which the piping path for supplying the primary steam and the piping path for supplying the secondary steam are configured by separate systems that do not merge.

In this regard, in the case of the conventional type, there are many cases where the reheated steam recovered for reuse and the system in which new steam joins in the middle of the pipe. In the present invention, the primary steam pipe and the secondary steam pipe for reusing recovered steam can be provided as separate systems. When the primary steam and the secondary steam are in the same system, there is a case where it is difficult to smoothly join the steam because the pressures of each other antagonize when the steams join.
For this reason, as shown in FIG. 1, it is preferable that the piping path for supplying the primary steam and the piping path for supplying the secondary steam are configured as separate systems that do not merge.

─ Steam temperature supplied from steam injection pipe ─
The steam temperature supplied to the noodle string group from the first steam injection pipe and the second steam injection pipe for reheated steam in the present invention is dry steam with reduced wetness, particularly when the noodle string group is targeted. It is preferable to use it.

The noodle string group M is conveyed in a state where a plurality (thousands) of thin noodle strings are intricate. When steaming the noodle strings, it is preferable that the amount of heat held is large. In other words, the total heat of saturated steam is the sum of sensible heat and latent heat, but increasing the degree of dryness can increase the amount of total heat by making it contain a lot of latent heat. preferable.

In the case of the present invention, the steam actually brought into contact with the noodle strings as described above is preferably a steam of about 100 ° C. and having a high dryness. For this reason, since a temperature drop may occur while the steam supplied from the first steam injection pipe reaches the noodle strings group, the superheated steam having a steam temperature of 100 ° C. or higher (about 100 ° C. to 120 ° C.) (Preferably about 103 ° C. to 115 ° C.).

In order to obtain a steam temperature higher than 100 ° C., it is basically necessary to use superheated steam. On the other hand, when the superheated steam of about 110 ° C. or higher directly contacts the noodle strings, the noodle strings may be affected. For this reason, it is preferable to adjust the temperature of the steam supplied from the steam injection pipe and the temperature of the steam that actually heats the noodle strings.

-Steam recovery mechanism-
In the first embodiment of the present invention, a steam recovery mechanism for supplying steam to the secondary steam injection pipe 15 is provided.

In the first embodiment of the present invention, a steam recovery duct 33 is provided for recovering the steam discharged from the hole provided in the outlet portion 5 protruding from the steam storage 1. The steam discharged from the steamhouse 1 is collected.
For the recovery duct 33, for example, a drain generation and recovery device as disclosed in JP-A-2015-75289 may be used to generate a vapor drain.
In addition, the drained recovered moisture is utilized / heated and vaporized again, and then supplied again into the vapor storage 1 from the second vapor injection pipe 15.

─Inlet duct and outlet duct─
In the first embodiment of the present invention, an exhaust inlet duct 35 is installed on the inlet side. Gas near the inlet 3 is sucked by the inlet duct 35. Since the steam supplied together with the noodle strings is also transported by the transport by the first conveyor 7 for transporting the noodle strings, the steam density in the vicinity of the inlet portion 3 is reduced, and the temperature may be lowered.

For this reason, the gas etc. of the inlet part 3 vicinity can be attracted | sucked by the inlet part duct 35. FIG. By these, the vapor | steam conveyed in the advancing direction of the 1st conveyor 7 can be returned to an inlet_port | entrance part, and while maintaining the vapor | steam density of an inlet_port | entrance part vicinity, it does not reduce temperature.
In the present invention, since the purpose is to efficiently perform the noodle string group M to be steamed, it is necessary to perform steaming efficiently in the steam supply portion. Therefore, a method of increasing the density and temperature of steam near the inlet by sucking steam in the tunnel-type steaming apparatus through which the noodle strings on the conveyor pass as described above is effective.

In the first embodiment of the present invention, an outlet duct 37 is also provided. The significance of the outlet duct 37 in the present invention is to increase the steam density in the vicinity of the outlet and raise the temperature by attracting the steam conveyed with the conveyor to the vicinity of the outlet as described above.

In addition, it is preferable that the temperature in the vicinity of the outlet portion 5 of the steamhouse, for example, in the vicinity of the outlet portion 5, is 98 ° C. or higher by using these outlet portion ducts 37. More preferably, it is 99 ° C. or higher. Thus, steaming efficiency can be raised by raising temperature to the vicinity of the exit part 5. FIG. In addition, the length of the steam storage can be minimized and the space can be used effectively.

Moreover, in the said 1st embodiment, although the case where the inlet part duct 35 and the outlet part duct 37 are installed is shown, this invention is not limited to this first embodiment, For example, the inlet part duct 35 is shown. Or the structure which does not have either or both of the exit part duct 37 may be sufficient. In addition, after the inlet duct 35 and / or the outlet duct 37 serves as the above-described steam recovery duct, a steam drain is generated and the recovered moisture that has been drained is used / heated, and then vaporized again. Alternatively, the second steam injection pipe 15 may be supplied again into the steam storage 1.

--Other aspects--
In the first embodiment of the present invention described above, the steam is sucked from the outlet portion 5 and reheated to use the secondary steam as the secondary steam. The steam recovery mechanism to be performed is not limited to the type of suction from the outlet portion 5, and for example, a method of recovering the steam from the inlet portion 3 in FIG. 1 is also possible. Further, a method of separately providing a hole in the wall of the vapor store 1 in addition to the inlet 3 and the outlet 5 described above and recovering the vapor from the hole is also possible.

In addition, the transport mechanism for the steamhouse and the noodle strings group is configured so that the noodle strings can be transported in three stages in the steamhouse in the first embodiment of the present invention, but is not limited thereto. Of course. That is, as shown in FIG. 3, a normal one-stage type is also possible.

Next, in the present invention, as a method of using steam more efficiently, a method of closing (filling) the void space in order to reduce the volume in the steam storage is also effective. That is, for example, as shown in FIG. 4, the space between the upper end of the steamhouse and the first conveyor 7 (air gap space (1) 39), and the space between the lower end of the steamhouse and the second steam injection pipe. A method of inserting a member that fills the (vacant gap space (2) 41), for example, a sealed plate-like body or the like, may be used. Thus, the steam can be used effectively by reducing the volume of the steam storage.
In addition, about a space | gap space, it is not limited above, For example, it is needless to say that other parts may be sufficient like the internal space (air gap space (3) 43) of a 2nd conveyor.
By filling these void spaces with members, the volume in the steam storage can be reduced and steam can be used effectively.

─ About movement of noodle strings ─
The noodle strings M cut out and conveyed on the conveyor are cooked as follows with reference to FIGS. 1 and 5. In the present invention, the noodle string group M before being cooked is cut out and transported, but generally, another transport conveyor (not shown) is arranged in front of the inlet portion 3 of the steaming apparatus, and before the steaming. A mode in which the noodle strings are conveyed is assumed. The noodle string group M delivered from the conveyor is conveyed into the tunnel-type entrance 3 and is conveyed in an obliquely upward direction, which is the direction of travel of the conveyor at the entrance 3, and is conveyed from the entrance 3 to the steamhouse. .

The noodle strings M transported in the steamhouse 1 are transported from the primary steam injection pipe 11 provided at the lower part of the mesh-like conveyor belt 27 during the transport in the forward direction of the first stage of the upper part of the steamhouse. Steamed with steam. By steaming on the upper side of the steamhouse 1 in this way, the steam then fills the steamhouse 1 from the upper part to the lower part, so that it is exposed to the steam that fills in this way, Steaming of the noodle strings M proceeds as the noodle strings M are conveyed alternately in the outlet direction and the inlet direction.

Specifically, the noodle string group M is conveyed as follows. That is, the noodle strings that are carried from the inlet 3 to the steamhouse 1 by the first conveyor 7 and conveyed in the outlet direction through the steamhouse 1 are noodle strings when the first conveyor 7 is reversed by the first sprocket 18. The group is also inverted and dropped onto the second conveyor 9 and delivered.
The noodle string group M that has fallen on the second conveyor 9 is conveyed in the direction of the entrance, and is further reversed on the inner diameter side of the second sprocket 19 and dropped again on the first conveyor 7 and delivered.

The noodle strings that have fallen on the first conveyor 7 will be conveyed again toward the entrance. A group of noodle strings conveyed in the direction of the inlet of the first conveyor 7 is conveyed to the outlet portion 5 of the steamhouse 1 and then discharged to the outside.
The steamed noodle strings M after being discharged are further conveyed by a separately installed conveyor (not shown in the drawing), and transferred to an arbitrary process, that is, an optional process such as seasoning, drawing, cutting, and frying. .

─Noodle line group─
The food to be cooked by the noodle strings steaming apparatus is noodle strings. Normally, when steaming noodle strings,
A plurality of noodle strings are steamed as shown in FIG. 4 while each noodle string is connected for a long time instead of being cut.

Therefore, for example, in the case of an instant noodle production line, since a plurality of noodle strings are transported in a connected state, the delivery from the first conveyor 7 to the second conveyor 9 or the second conveyor 9 to the first conveyor 7 is performed. The noodle strings can be transferred smoothly in the delivery to. Moreover, since the noodle strings M to be transported carry steam, the inside of the refrigerator can be made to be in a state where steam is accumulated.

The noodle string group M cooked by the steaming apparatus of the present invention can be used in various ways. For example, the steamed noodle strings can be cut and packaged for use as steamed noodles (steamed noodles). Moreover, after steaming, it can be made into a fried noodle mass or a hot-air dried noodle mass by passing through steps such as pulling, seasoning, cutting and filling with a retainer, and then fried or hot-air dried.
