Description

The present invention relates to a drying device for producing non-fried noodles, and more specifically, for producing non-fried noodles by blowing hot air into a noodle mass that is carried in a retainer for each serving and dried. It relates to a drying device for producing non-fried noodles.

In general, instant noodles are made by kneading flour and water to produce dough, rolling the dough into noodle strips, cutting out the noodle strips, cutting the noodle strings for each serving, putting them in a retainer, and drying them. After being treated to remove water, it is commercialized through a cooling process. The drying treatment at that time includes a method of frying with oil and fat to remove water and a method of hot air drying to remove water, and the latter is called non-fried noodles.

In the production of non-fried noodles, a method is generally adopted in which a noodle mass, which is placed in a retainer for each serving and is conveyed by a conveyor, is dried by blowing hot air from above and below. As an apparatus for that purpose, for example, a pipe nozzle type drying apparatus as described in Japanese Patent Application Laid-Open No. 2000-146401 and Japanese Patent No. 5666260 is known. This pipe nozzle type drying device is composed of chambers provided with a large number of pipe nozzles for ejecting hot air on the upper and lower sides of a conveyor that continuously conveys a large number of retainers containing a large number of noodle lumps for one serving.

In the case of this device, each pipe nozzle is attached so as to project downward from the bottom surface of the upper chamber and also to project upward from the top surface of the lower chamber. A hot air duct extending from a hot air blower provided with a heater is connected to each of the upper chamber and the lower chamber on one side surface, and hot air from the hot air blower is blown through the hot air duct.

Japanese Unexamined Patent Publication No. 2000-146401 Japanese Patent No. 5666260

As described above, hot air is blown into the upper and lower chambers from the hot air duct installed on the side surface, but the dynamic pressure of the hot air increases as the distance from the injection port increases, which is related to the ejection speed from the pipe nozzle. The static pressure is low. Since each pipe nozzle is arranged over the bottom surface of the upper chamber and the entire top surface of the lower chamber, the dynamic pressure received by each nozzle varies greatly depending on the arrangement position and is blown out from the pipe nozzle. As a result of the non-uniform wind velocity distribution, the dry state of the noodle mass becomes uneven. In particular, in the case of a mass-produced machine in which the width direction in the traveling direction is divided into 8 to 20 servings and the width is widened to 1200 to 3200 mm, the variation becomes large.

In order to deal with this problem, it is conceivable to provide a wind direction plate in the chamber to disperse the dynamic pressure so that the flow velocity of each outlet pipe from the chamber becomes uniform. However, in order to achieve uniform dynamic pressure by this method, it is necessary to increase the height of the chamber as the number of pipes increases. Specifically, assuming that the length of the chamber is 1.5 m in the traveling direction, the height must be about 700 mm, which is about half of the length, and these are arranged vertically, and further, a protruding pipe. When the lengths of the nozzles are added, the total height is about 2 m.

In the case of the current non-fried noodle equipment, the drying time is 40 minutes or more, so that the length of the equipment is longer than that of the equipment for fried noodles. Therefore, there is a problem that a large space is required for the new introduction and the cost increases. In order to save the installation space, it is conceivable to increase the number of chambers, but since there is a demand to increase the chamber height as described above, it is realistic to use a chamber with a conventional configuration to increase the number of stages. is not it.

The present invention has been made to solve such a problem in the conventional apparatus, and the hot air supplied into the upper and lower chambers is blown out from a large number of pipe nozzles arranged over a wide area only by static pressure. Therefore, the flow rate of the hot air blown from all the pipe nozzles toward the noodle mass is made uniform so that the noodle mass can be dried evenly, and the height of each of the upper and lower chambers is lowered. It is an object of the present invention to provide a drying device for non-fried noodle production, which can be installed in a not so large space because each chamber can be configured in a multi-stage facility. ..

The invention according to claim 1 for solving the above-mentioned problems is a conveyor that continuously conveys a large number of retainers that can be ventilated in the vertical direction in which one serving of noodle mass is charged, and is arranged on the upper side and the lower side of the conveyor. It is a drying device for producing non-fried noodles, which consists of a hot air injection unit.
The upper hot air injection unit has an upper chamber in which a large number of hot air injection pipe nozzles protruding downward are arranged on the bottom surface, and the lower hot air injection unit has a hot air injection projecting upward on the top surface. It has a lower chamber with a large number of pipe nozzles for
The rear end of the pipe nozzle disposed in the upper chamber projects into the upper chamber, and the rear end opening extends so as to straddle the rear end opening of the plurality of pipe nozzles. The rear end of the pipe nozzle, which is covered with an appropriate interval and is disposed in the lower chamber, protrudes into the lower chamber, and the rear end opening is of a plurality of the pipe nozzles. It is a drying apparatus for producing non-fried noodles, characterized in that it is covered with a closing cover extending so as to straddle the rear end opening while maintaining an appropriate interval.

In one embodiment, the closing cover is composed of a top plate having an inverted U-shaped cross section and an end face closing material that closes both ends of the top plate, and the end face closing material is the pipe located at the most end. It is composed of a bottom plate provided with an opening through which the rear end portion of the nozzle is inserted, an end face plate rising from the bottom plate, and a top plate fixing portion extending to the upper end of the end face plate, and the rear end opening of the pipe nozzle and the said. The distance from the closing cover is maintained by the end face plate.

In one embodiment, the pipe nozzle is fixed to the bottom surface of the upper chamber and the lower chamber is fixed to the top surface by using a pair of speed washers.

The method for fixing a pipe according to claim 4 used for fixing the pipe nozzle is a method for fixing the pipe to a flat plate in a state in which the pipe protrudes vertically, and the pipe is opened in an opening formed in the flat plate. This is a method for fixing a pipe, which comprises inserting and fitting speed washers to the pipe from above and below, and sandwiching the flat plate with the upper and lower speed washers.

The present invention is as described above, and the rear end openings of the pipe nozzles protruding into the upper and lower chambers are appropriately spaced by a closing cover extending so as to straddle the rear end openings of a plurality of pipe nozzles. Since it is covered, the hot air supplied into the upper and lower chambers is ejected only by static pressure from a large number of pipe nozzles, and thus the flow velocity of the hot air ejected from all the pipe nozzles toward the noodle mass. The noodle mass is dried evenly, and the height of each of the upper and lower chambers can be kept low, making it possible to have a multi-stage equipment configuration for each chamber. It has the effect of being able to be installed in a small space.

It is a front vertical sectional view of the main part of the drying apparatus for manufacturing non-fried noodles which concerns on this invention. It is a side sectional view of the main part of the drying apparatus for manufacturing non-fried noodles which concerns on this invention. It is an exploded perspective view which shows the structure of the blockage cover, and the installation method of a pipe nozzle in the drying apparatus for manufacturing non-fried noodles which concerns on this invention.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a main part of a drying device for producing non-fried noodles according to the present invention, FIG. 2 is a front sectional view of the main part, and FIG. 3 is a side sectional view of the main part. The device installs a conveyor 3 that continuously conveys a large number of retainers 1 that can be ventilated in the vertical direction in which one serving of noodle mass 2 is put in a frame (not shown), and hot air is placed on the upper side of the conveyor 3. The injection unit 4 is arranged, and the hot air injection unit 5 having the same configuration as the hot air injection unit 4 and upside down is arranged on the lower side.

For example, the conveyor 3 is a series of retainer receiving plates for setting a large number of retainers 1 side by side in the traveling direction. The retainer 1 has a net plate on the bottom surface and an open sieve-like top surface, and is covered with a net lid during hot air drying treatment, if necessary.

The upper hot air injection unit 4 has an upper chamber 6 in which a large number of hot air injection pipe nozzles 7 projecting downward are arranged on the bottom surface 6a. The rear end portion of the pipe nozzle 7 penetrates the bottom surface 6a and protrudes into the upper chamber 6, and the rear end opening portion 7a is covered with the closing cover 8 while appropriately maintaining an interval h (see FIGS. 2 and 3).

The closing cover 8 is composed of a top plate 8a having an inverted U-shaped cross section and an end face closing member 9 that closes both ends of the top plate 8a in the length direction (see FIG. 4). The top plate 8a is a long plate extending so as to straddle the rear end openings 7a of the plurality of pipe nozzles 7, and side plates 8b are extended on both long sides thereof. The end face closing material 9 includes a bottom plate 9a provided with an opening 9b through which a rear end portion facing into the upper chamber 6 of the pipe nozzle 7 located at the end is inserted, an end face plate 9c rising from the bottom plate 9a, and an upper end of the end face plate 9c. It is composed of a top plate fixing portion 9d extending to. The distance h between the rear end opening 7a of the pipe nozzle 7 and the top plate 8a of the closing cover 8 is maintained by the end face plate 9c.

In a preferred embodiment, the pipe nozzle 7 is fixed to the bottom surface 6a of the upper chamber 6 by co-fastening with a pair of speed washers 11 and 12. The speed washers 11 and 12 are metal plates in which a notch is made in the radial direction from the central opening, and there are various shapes. As will be described later, in the present invention, the gap between the protrusion amount in the upper chamber 6 of the pipe nozzle 7 (start-up amount H ₀ ) and the rear end opening 7a of the pipe nozzle 7 and the top plate 8a of the closing cover 8. h but is important, if by a fixed method using speed washers 11 and 12, ensuring that a predetermined protrusion amount, i.e., it is easy to set the start-up amount H _0.

In that case, first, the pipe nozzle 7 is inserted into the lower speed washer 11 located on the lower side, and the pipe nozzle 7 is moved to a fixed position (a predetermined distance from the rear end opening 7a) (see FIG. 4). The rear end portion of the pipe nozzle 7 is inserted through the insertion hole 6b of the bottom surface 6a of the upper chamber 6 until the lower speed washer 11 hits the bottom surface 6. In that state, the upper speed washer 12 to be located on the other upper side is fitted to the rear end portion of the pipe nozzle 7, and the upper speed washer 12 is slid downward and finely adjusted until it hits the bottom surface 6a. Thus, the pipe nozzle 7 is supported by a pair of speed washers 11 and 12 with the bottom surface 6a interposed therebetween, and is fixed to the bottom surface 6a in a state of projecting into the upper chamber 6 by a predetermined amount.

The pipe nozzles 7 are arranged at regular intervals in the vertical and horizontal directions on the bottom surface 6a of the upper chamber 6, but for the pipe nozzles 7 at both ends of the long row, the rear end portion of the pipe nozzle 7 is before the upper speed washer 12 is fitted. Is passed through the opening 9b of the bottom plate 9a of the end face closing material 9 to arrange the end face closing material 9. Then, the upper speed washer 12 is fitted in the same manner as described above. Therefore, the pair of speed washers 11 and 12 that support and fix the pipe nozzles 7 at both ends sandwich the bottom plate 9a of the end face closing member 9 and the bottom surface 6a of the upper chamber 6 (see FIGS. 2 and 4).

The lower hot air injection unit 5 has basically the same configuration as the upper hot air injection unit 4, and is arranged so as to be upside down with the upper hot air injection unit 4 with the conveyor 3 interposed therebetween. That is, the lower hot air injection unit 5 includes a large number of pipe nozzles 7 for hot air injection projecting upward on the top surface thereof.

The upper and lower chambers 6 and 6a in which the pipe nozzle 7 is installed have an injection port (not shown) inside the chamber, and hot air is blown from this injection port in a small area with respect to the chamber volume. Since the pipe is blown at a high speed, the air volume distribution to the pipe nozzle 7 in the chambers 6 and 6a is biased due to the dynamic pressure of the blown flow velocity. Therefore, in the present invention, the closing cover 8 is provided in order to eliminate the influence of this dynamic pressure and to make the flow velocity of the hot air sent from the many existing pipe nozzles 7 uniform.

That is, the hot air blown into the chambers 6 and 6a flows in the direction perpendicular to the pipe nozzle 7, hits the wall facing the pipe nozzle 7, and flows in various directions. The hot air whose flow direction has changed in the direction parallel to the pipe nozzle 7 (vertical direction) has a large flow velocity and is discharged from the pipe nozzle 7. However, when the blockage cover 8 is installed, the hot air is discharged from the pipe nozzle 7. Since the portion corresponding to the inlet of the pipe nozzle 7 is closed, hot air is not directly discharged from the pipe nozzle 7. Further, the hot air that is about to flow into the pipe from around the inlet of the pipe nozzle 7 in a direction perpendicular to the direction is blown into the chambers 6 and 6a, and the hot air that flows in the direction perpendicular to the pipe nozzle 7 and the flow direction are different. Because they are the same, they are affected. In order to avoid the influence, side plates 8b are extended on both sides of the top plate 8a of the closing cover 8.

In order to make the entire chambers 6 and 6a uniform, it is conceivable to narrow the passage area flowing into the pipe nozzle 7 to increase the ventilation resistance, but in such a case, the pressure loss to the blower becomes large. The efficiency deteriorates. Therefore, the size and installation of the closing cover 8 so that the inflow passage area of hot air, that is, the passage area between the side plate 8b of the top plate 8a and the pipe nozzle 7 is as equal as the discharge cross-sectional area of the pipe nozzle 7. It is preferable to design the position. In such a case, a uniform resistance pressure loss is obtained, and a flow velocity due to a pressure difference due to static pressure can be obtained from the pipe. If the static pressure inside the chambers 6 and 6a is constant, the discharge flow velocity will be the same at any part.

In the case of the non-fried noodle manufacturing drying apparatus according to the present invention having the above configuration, a large number of retainers 1 in which one serving of noodle mass is charged and set on the retainer receiving plate 2 are continuously conveyed by the conveyor 3 and the upper and lower pipes. It passes through the hot air injection area sandwiched between the nozzles 7 and 7.

The hot air continuously jetted from the upper pipe nozzle 7 is jetted from above toward the noodle mass 2 in the retainer 1 to dry the noodle mass 2, pass through the retainer 1 and the conveyor 3, and then pass through the retainer 1 and the conveyor 3, and then the lower chamber. It flows out as return air through the gap between the pipe nozzles 7 of No. 5 (see FIG. 1). Similarly, the hot air continuously jetted from the lower pipe nozzle 7 is jetted from below toward the noodle mass 2 in the retainer 1 to dry the noodle mass 2, and after passing through the retainer 1 and the conveyor 3. , It flows out as return air through the gap between the pipe nozzles 7 of the upper chamber 4.

The drying device for producing non-fried noodles according to the present invention is as described above, and the rear end openings of the pipe nozzles protruding into the upper and lower chambers are closed so as to extend over the rear end openings of the plurality of pipe nozzles. Since the cover covers the upper and lower chambers at appropriate intervals, the hot air supplied into the upper and lower chambers is blown out from a large number of pipe nozzles only by static pressure, and thus all the pipe nozzles form a noodle mass. The flow velocity of the hot air blown toward the pipe is made uniform, the noodle mass is dried evenly, and the height of each of the upper and lower chambers can be kept low. It has the effect of being able to be installed in a space that is not so large, and its industrial utility is great.
