[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a noodle-boiling device, and more particularly to a device for boiling pasta in a short time under high pressure and high temperature.

[0002]

2. Description of the Related Art As a noodle-boiling device of the above-mentioned type, there is one already disclosed in Japanese Utility Model Publication No. 5-85318. In this device, high-pressure hot water is stored in a processing tank for boiling noodles. , Noodles are added to this.
According to this, since the noodles are boiled by the hot water maintained at a temperature higher than 100 ° C., the noodles can be boiled in a shorter time than when boiled under atmospheric pressure.

Boiled noodles are discharged together with the hot water used for them. Therefore, in order to continuously boil noodles by the above method, it is necessary to prepare this high-pressure high-temperature hot water in a short time. Therefore, in this conventional technique,
A plurality of heating tanks are prepared so that hot water having a predetermined temperature is finally obtained while passing through the plurality of heating tanks. Therefore, hot water having a predetermined temperature is prepared in the heating tank before the processing tank, and after completion of the noodle boiling treatment, the noodle boiling can be performed using the hot water in the heating tank.

Therefore, this conventional one has an advantage that the noodle boiling operation can be continuously performed in a short time. However, in this conventional one, since a plurality of heating tanks are prepared separately from the processing tank, when the work of one day is completed, work for discharging hot water from the heating tank is required, and Since it is necessary to prepare at least several heating tanks having the same size as the processing tank, the entire apparatus becomes large accordingly.

The present invention has been made in view of the above points, and in a noodle-boiling apparatus in which noodles are boiled under high-pressure and high-temperature conditions, a plurality of heating tanks are not used separately from the treatment tank, It is an object of the present invention to make it possible to prepare high-pressure and high-temperature hot water so that the processing time of the noodle-boiling work can be shortened and the entire apparatus can be downsized.

[0006]

[Technical Means] The technical means of the present invention for solving the above-mentioned problem is that "the upper and lower ends of a thick-walled iron cylinder (11) are provided by a top wall (12) and a bottom wall (13). The treatment tank (1) is formed by closing it, and a conductor wire is wound around the body of the treatment tank (1) to form an electromagnetic heating coil (2), and an electromagnetic induction current is applied to the tubular body (11). The electromagnetic heating coil is used to generate an electric current
(2) is provided with an electromagnetic unit (20) to preheat the tubular body (11) to a predetermined temperature by electromagnetic induction heating, and at the time of noodle boiling, the tubular body (11) is set to a temperature higher than 100 ° C. A control device (3) for controlling the electric supply from the electromagnetic unit (20) to the electromagnetic heating coil (2) to maintain

Therefore, the hot water in the treatment tank (1) is quickly heated to the set temperature and heated.
The noodles are added when the stored hot water in the treatment tank (1) is heated to the set temperature in this manner or in advance thereof.

When the noodles are boiled, the cylinder is
The set temperature higher than 00 ° C is maintained. Therefore, the noodles are boiled up in a short time like the conventional one.
When boiled, the outlet (15) of the bottom wall (13) is opened and the noodles are discharged together with warm water.

At this time, the cylindrical body (11) has already been preheated to the above set temperature. Therefore, after boiled up, the above-mentioned series of operations can be continuously performed.

[0011]

[Effect] Since a plurality of heating tanks are not prepared unlike the conventional one, the entire size can be reduced as compared with the conventional one. Further, since the tubular body (11) constituting the processing tank (1) is heated by electromagnetic induction heating, it can be heated at a higher speed than that by a conventional electric heating device.

In this device, the heating temperature rising region becomes small, so that the room temperature water is treated in the treatment tank (1). The heating and heating time to the set temperature can be shortened as compared with the case of supplying water to (). The invention of claim 5 is that “the openable and closable noodles input port (14) and the freely openable and closable discharge port (15) are both ball valves”. At this time, since all the mouths are fully opened until they coincide with the cross section of the passage, the noodles can be charged and discharged smoothly, and the sealed state in the closed state can be ensured.

According to this, when the set amount of water is supplied to the treatment tank (1) after the water is supplied, the treatment time can be shortened while minimizing the bumping phenomenon in the treatment tank (1). There are advantages.

After that, the noodles input port (14) is opened to add pasta, and after the addition, the noodles input port (14) is closed. Then, the adjusted temperature is set to the high temperature side set temperature (130 ° C.). By the output of the control device (3), the temperature of the cylindrical body (11), that is, the temperature of the hot water in the processing tank (1) is maintained at 130 ° C.

When the set temperature is reached, the timer (T) turns "on". Timer (T) setting time (eg 15
After 0 to 200 seconds), the pasta in the processing tank (1) is boiled up. Therefore, at this time, the noodles inlet (14) and the outlet (15) are opened and the pasta in the treatment tank (1) is taken out together with hot water. Then, the noodles inlet (14) and the outlet (15) are closed again, the set temperature is switched to 120 ° C., and the next noodle boil is put into a standby state.

Then, the start switch (61) is turned on.
Then, the series of operations described above is executed. The tubular body (11) of this embodiment is made of an iron body so that two servings of pasta can be boiled at the same time. Therefore, the inner diameter of the cylindrical body (11) is 70 mm and the effective internal volume is 1129C.

In this product, the through hole of the plug (V) of the electric ball valve is provided as the noodles inlet (14) and outlet (15), and in the standby stage before water supply to the treatment tank (1). The plug
(V) is opened to open both the noodle inlet (14) and the outlet (15). Exhaust valve (53) and safety valve (54)
Are connected to the large diameter part (10) through the top wall (12), and the water supply circuit (4) is also connected to the large diameter part (10) through the on-off valve (41). There is. The configuration of the control device (3) and the configuration of the water supply control unit are the same as in the first embodiment.

The control device of this embodiment is configured to execute the flow chart shown in FIG. Prior to the noodle-boiling treatment, the cylindrical body (11) was subjected to the first preset temperature (120 ° C.) by the electromagnetic heating coil (2) as in the case of the above-mentioned Example 1.
Has been preheated. At this time, the noodles inlet (14) and the outlet (15) are both open. After this, the water supply operation is executed. As a matter of course, the outlet (1
5) is closed, and then the on-off valve (41) is opened.

After the water supply is completed, the value of the set temperature signal (312) is switched to the second set temperature (100 ° C.), and the cylinder (1
The temperature of 1) is maintained at the second set temperature. Usually, the temperature of this cylindrical body (11) and the temperature of the hot water in the processing tank (1) are 2-3 ° C.
Therefore, the temperature of the hot water in the treatment tank (1) in this state is about 97 to 98 ° C. Then, the pasta is thrown in, the noodles feeding port (14) is closed, and the boil-up operation is executed. At this time, since the processing tank (1) is a closed container, the internal pressure is higher than atmospheric pressure.
The temperature of the hot water inside may be 100 ° C. or higher.

When the noodles are boiled, the value of the set temperature signal (312) is switched so that the tubular body (11) moves to the third set temperature (130).
℃) is maintained. That is, the control device (3) controls so that the temperature detected by the temperature sensor (31) is maintained at the third set temperature. Then, the time from the time when the temperature reaches the third set temperature is measured by the timer (T),
When the set time (for example, 200 seconds) elapses, the set temperature for heating and retaining the tubular body (11) is switched to the first set temperature, and the exhaust valve (53) is temporarily (about 0.5 to 1 second). After that, the noodles inlet (14) remains closed,
The outlet (15) is opened, and the boiled noodles are taken out. At this time, the noodles inlet (14) is closed,
When the noodles are taken out, the inconvenience and danger caused by the rapid discharge of hot water and noodles can be eliminated.

After that, by controlling the electromagnetic unit (20),
The temperature of the cylindrical body (11) is controlled to the first set temperature. In addition, when the noodle boiling operation is continuously performed, it is possible to wait until the temperature of the tubular body (11) is raised to the first set temperature and then perform the water supply operation. When the water supply operation is executed at a stage where the first set temperature is not reached, the second set temperature may be maintained immediately after the water supply without maintaining the first set temperature.

In the second embodiment shown in FIG. 3, the temperature sensor (31)
Since the tip of the temperature detection part of is configured to reach the vicinity of the inner peripheral surface of the treatment tank (1), that is, the vicinity of the inner peripheral surface of the tubular body (11), it is stored in the treatment tank (1). Water or hot water temperature,
Since the difference from the temperature detected by the temperature sensor (31) is reduced, the temperature detection accuracy of the temperature sensor (31) is improved. [Others] In the above embodiment, the electromagnetic unit (20) is turned on.
By turning off and comparing the detected temperature signal (311) from the temperature sensor (31) with the set temperature signal (312), the set temperature is maintained, but the value of the set temperature signal (312) is The first set temperature, the second set temperature,
It is configured to be switched to each of the third set temperatures.

In each of the above embodiments, the room temperature water is supplied from the water supply circuit (4) into the treatment tank (1).
The hot water from the hot water supply device (42) may be supplied from the water supply circuit (4). In the above embodiment, when the boiled noodles are taken out, the exhaust valve (53) is opened for a certain period of time to reduce the internal pressure, but instead of this, control should be performed to execute the flowchart shown in FIG. Is also possible.

In this method, when the noodles are taken out, the exhaust valve (53) is opened and the water supply to the treatment tank (1) is started (ST01), and then the temperature in the treatment tank (1) is changed to the first value. 2 It detects that the temperature has dropped to the set temperature (ST02), then stops the water supply (ST03), and then takes out the pasta. In other words, when taking out the noodles, "the pressure in the treatment tank (1) is lowered to the atmospheric pressure and the temperature in the treatment tank (1) is lowered to the boiling point of water or less before taking out the noodles". is there.

By the way, a treatment tank suitable for the conditions above the boiling point
The heated water in (1) is boiled and vaporized by opening the exhaust valve (53). If the opening time of the exhaust valve (53) is set to be long, the heated water in the treatment tank (1) may be completely vaporized in some cases. Therefore, the exhaust valve (5
It is necessary to set the time until the noodles are taken out after the valve is opened in 3) by an experiment, and it is troublesome to work out the appropriate value.

However, in the method shown in FIG. 5, the temperature of the heated water is lowered to high temperature water having a boiling point or lower by supplying water, and the noodles are discharged together with the high temperature water, so that the noodles can be safely and smoothly supplied. You can take out the noodles.
In addition, it is easy to set the timing of taking out the noodles. It should be noted that in any of the above-described embodiments, when pasta is turned on, a pasta turning switch (not shown) is operated after the pasta turning is completed, and the fact that the pasta turning operation has ended is indicated by the pasta turning switch. Is input as the "ON" signal.

Therefore, in the step (ST04) of "putting in pasta and then closing noodles inlet (14)" in each flowchart, it is actually judged whether or not the pasta-introducing switch is "ON", and "ON" is determined. If there is, it is configured to move to the next step. In addition, in the step (ST05) of "Ejection port (15): open, take out pasta", a detection switch (not shown) for detecting the opening of the ejection port (15) is provided, and this detection switch is turned on. It is determined whether or not it is “ON”, and if “ON”, the process moves to the next step.
