BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating container for heating a food material to produce a food such as bean paste, boiled vegetables or prepared foods.

[0002]

2. Description of the Related Art As the conventional heating container described above,
The one shown in FIG. 4 is known. This heating container 100
Has an opening 101 at the top for introducing the above food ingredients, and an outer frame 102 into which steam is sent at the bottom. In other words, the bottom of the heating container 100 has a double pot structure.

An outlet of a pipe 103 for supplying steam is provided in communication with the outer frame 102, and an inlet of a pipe 104 for discharging the steam supplied to the outside is in communication with the outer frame 102. It is provided. Therefore, the pipe 103
The steam sent via the pipe passes between the bottom of the heating container 100 and the outer frame 102 and is discharged from the pipe 104. At this time, the bottom portion of the heating container 100 is heated by the steam, and the food material placed inside the heating container 100 is heated by the bottom portion.

Since the food material is burnt only when it is heated, a stirrer 105 for stirring the food material is provided. This stirring device 105 is a heating container 100.
It is provided to rotate inside.

[0005]

However, in the case of the conventional heating container, the heat escapes from the opening, so that it is necessary to raise the heating temperature. As a result, the food material is stirred by the agitator 105. There was a problem that it was not possible to prevent burning by just stirring. Also,
There is also a drawback that the environment around the heating container deteriorates because hot air and steam containing a large amount of water flow out of the heating container through the opening.

[0006] The present invention has been made to solve the problems of the prior art, and an object thereof is to provide a heating container capable of preventing burning and improving the surrounding environment.

[0007]

A heating container of the present invention has an opening, a container main body in which a food material to be heated is placed, a heating means for heating the bottom of the container main body, and the opening. A lid for closing the portion, means for introducing superheated steam into the inside of the container body whose opening is closed by the lid, and water present inside the container body whose opening is closed by the lid And at least one of the air containing water is taken out to the outside of the container body whose opening is closed by the lid, thereby achieving the above object.

In the heating container of the present invention, the air containing water extracted to the outside of the container body whose opening is closed by the lid by the extracting means is separated into an air component and a water component. It is preferable to further include a circulation means for returning the separated air to the inside of the container body again.

[0009]

The heating container according to the present invention has the lid for covering the opening, so that the inside of the heating container is sealed.
It becomes possible to lower the heating temperature of the bottom of the heating container,
Therefore, it becomes possible to prevent burning. Also,
Due to the presence of the lid, hot air containing a large amount of steam or water generated when the food material is heated does not flow out through the opening of the container body. Further, if the lid is provided with a water outlet such as a drain port, the water droplets condensed inside the lid can be discharged to the outside through the water outlet.

Further, when the air-containing water is separated into an air component and a water component and the circulating air is returned to the inside of the container body, the opening is closed by the lid. Moisture inside the container body is gradually removed by the circulation means. At this time, by measuring the amount of water generated by the circulation means, it becomes possible to grasp the amount of water remaining inside the container body whose opening is closed by the lid, and the relationship with the water can be obtained. It is possible to make a food in which the characteristics of a certain food, such as viscosity, are in a desired state.

[0011]

EXAMPLES Examples of the present invention will be specifically described below.

(Embodiment 1) FIG. 1 is a front view showing a heating container according to this embodiment. This heating container comprises a container body 1 in which a food material to be heated is put. This container body 1 has an opening 2 at the top and an outer frame 3 on the outside at the bottom. In other words, the bottom of the container body 1 has a double hook structure.

The outer frame 3 is provided with an outlet of a pipe 10 for supplying steam in a communicating state, and an inlet of a pipe 11 for discharging the steam supplied inside is in a communicating state. It is provided. Therefore, the steam sent through the pipe 10 passes between the bottom portion of the container body 1 and the outer frame 3, and is discharged from the pipe 11. At this time, the bottom portion of the container body 1 is heated by the steam, and the food material placed inside the container body 1 is heated by the bottom portion. The temperature of the steam is preferably around 110 ° C. to prevent the food material from sticking to the container body 1. In addition, a total of 6 stirrers 30 for stirring food materials are provided inside the container body 1.
The rotary shaft 31 is provided on the rotary shaft 31. The rotary shaft 31 exists through the inside of the container body 1, but the space between the rotary shaft 31 and the container body 1 is sealed by a seal member (not shown). ing.

The opening 2 of the container body 1 is provided with a lid 5 for closing the opening. The lid 5 is suspended from an arm 6 and can be opened and closed by a driving unit (not shown) that drives the arm 6. By this opening and closing, the lid 5 reciprocates between the position that covers the opening 2 of the container body 1 and the standby position. The lid 5 is closed by bringing the peripheral edge of the lower end of the lid 5 into contact with the lid receiver 4 projecting on the outer surface of the container body 1 in the vicinity of the opening 2.

The container body 1 is provided with a steam blowing port 7 for blowing superheated steam. The superheated steam sent from the steam blowing port 7 is supplied to the inside of the container body 1 whose opening 2 is covered with the lid 5. The supplied superheated steam is used to supplement the insufficient temperature, because it is difficult to sufficiently raise the temperature of the food material by heating with the steam supplied to the inside of the double cauldron structure. Although the temperature of the superheated steam varies depending on the type of food to be heated, it may be a temperature that can assist the insufficient temperature as described above. Further, the lid 5 is provided with a drain port 8 for discharging the water droplets condensed inside the lid to the outside. The drain port 8 is formed so as to penetrate the lid 5 and has a function of passing the above-mentioned water droplets to the outside.

Further, the lid 5 is provided with an inlet of a pipe 20 for communicating air containing water existing inside the container body 1 to the outside of the container body in a communicating state. This pipe 20
A suction fan 21 is provided at the outlet of the container 1. Due to the suction force of the suction fan 21, the moisture-containing air present inside the container body 1 is taken out of the container body 1 through the pipe 20. Be done.

The outside of the suction fan 21 has an outer wall member 2
The air, which is covered with 1a and is taken out to the outside by the suction fan 21, passes through the inside of the outer wall member 21a and is sent to the air / water separator 22 provided below the suction fan 21. To be The air / water separator 22 has a double tube structure, and the suction fan 21 is passed through the inner tube.
Air containing water passes through. On the other hand, the outer pipe is provided with a cold water inlet 24 for supplying cooling water and a cold water outlet 23 for discharging the cooling water supplied from the cold water inlet 24. The moisture-containing air sent through the inner pipe is separated into moisture and air components by the steam separator 22. The separated water is discharged to the outside through a drain port 25 provided so as to connect the inner pipe of the steam separator 22 to the outside. On the other hand, the air from which the water has been separated remains at a relatively warm temperature, and the inlet is connected to the inner pipe of the steam separator 22 and the outlet is connected to the inner space of the lid 5 via the pipe 26. And returns to the inside of the container body 1 again. The air / water separator 22 and the pipe 26 constitute a circulation means.

The operation of the thus constructed heating container of this embodiment will be described by taking the manufacturing of bean paste as an example. First, the bean paste material is put into the container body 1 through the opening 2. continue,
The lid 5 is moved from the standby position to cover the opening 2 with the lid 5. Further, cooling water is supplied to the steam separator 22 from the cold water inlet 24, and the suction fan 21 is operated.

When the preparation is completed, next, the inside of the double kettle structure composed of the outer frame 3 and the bottom of the container body 1 is
Steam is supplied from the pipe 10. Thereby, the container body 1
The bottom of the container is heated to heat the bean paste material placed inside the container body 1. At this time, the stirrer 30 provided on the rotary shaft 31 is rotated so that the bean paste material does not burn even when heated. Further, with the heating of the bean paste material, steam is generated inside the container body 1. The air containing the steam and moisture is taken out of the container body 1 through the pipe 20 by the suction force of the suction fan 21.

The air containing water taken out by the suction fan 21 is sent to the air-water separator 22,
Here, it is separated into water and air components. The separated water is discharged to the outside through the drain port 25, and the air from which one of the water has been separated returns to the inside of the container body 1 again via the pipe 26 while maintaining a relatively warm temperature.

At this time, there is a difference in the amount of water entering the container body 1 via the air due to the temperature of the air from which the water content is returned to the inside of the container body 1. For example, when the temperature of the air sent to the steam separator 22 is 80 ° C., the saturated wetness is 0.546 kg, and when the temperature of the air passing through the steam separator 22 is 30 ° C., the saturated wetness is 0. .02
71 kg, and similarly, at 40 ° C., the saturated wetness was 0.
It becomes 04884 kg. However, the steam separation device 2
About 1 degree due to the temperature drop from the temperature of the air sent to the steam separator 22 rather than the degree of difference due to the temperature of the air passing through 2.
It is remarkably large that it is reduced to / 10 to 1/20.

While maintaining such a state, the container body 1
When the bean paste material inside is heated to a temperature of about 75 ° C., superheated steam is supplied to the inside of the container body 1 through the steam injection port 7. By supplying this superheated steam, the bean paste material can be heated to a predetermined temperature,
For example, it is heated to 100 ° C. When the temperature reaches the predetermined temperature, the supply of superheated steam is stopped.

Here, the opening 2 of the container body 1 is the lid 5
Is in an airtight state, and superheated steam is supplied into the airtight atmosphere. In addition, the dry air from which water has been separated by the air / water separator 22 is circulated in the airtight container body 1 by the circulation means. Therefore, since the entry of moisture from the outside is prevented, it becomes possible to grasp the amount of moisture remaining in the bean paste material with the elapsed time of the heating. To grasp the water content, for example, the steam separation device 2
A water meter may be provided at the drain port 25 of No. 2, and the operation can be performed based on the water quantity detected by the water meter. As a result, it is possible to manufacture a bean paste in which the viscosity, sugar content, weight, etc., which are related to the amount of water, are set in predetermined states. Although the superheated steam contains water, its content rate is not so high that it does not affect the grasp of the amount of water remaining inside the container body 1 in which the opening 2 is closed by the lid 5. Not much.

(Embodiment 2) Another embodiment of the present invention will be described.

FIG. 2 is a front view showing the heating container according to the second embodiment. This heating container has a steam / water separator 22, but does not return the air after the water has been separated by the steam / water separator 22 to the container body 1, that is, the pipe 26 shown in FIG. 1 is omitted. There is.

In the case of this embodiment, the steam separation device 2
Since the air is released after passing 2, the temperature of the air becomes relatively low and the surrounding environment can be improved.

(Embodiment 3) This embodiment is a case where the present invention is applied to a heating container having a barrel-like shape.

FIG. 3 is a front view showing the heating container according to this embodiment. Note that, in FIG. 3, the same reference numerals are given to portions that perform the same functions as in FIG. This heating container has a configuration in which a lid 41 closes the opening 2 of a container body 40 having a barrel shape with a vertical axis. Further, inside the container body 40, a stirrer 42 is attached to a rotary shaft 43 whose axis is oriented in the vertical direction. Further, this heating container is not provided with a circulation means composed of a steam separator and a pipe, and superheated steam is supplied from the steam inlet 7 to the inside of the container body 1 and condensed inside the lid. Water droplets are discharged from the drain port 8 to the outside.

Therefore, since the heating container according to this embodiment has a relatively high bulk structure, the lid 41 causes the superheated steam supplied to the inside of the container body 1 to be a water drop. It functions as an air / water separator.
Therefore, the water is discharged not as steam but as water with dew condensation. Therefore, in the present embodiment, the steam separation device is not provided. Incidentally, in order to further improve the efficiency of air-water separation, a structure may be provided with a water-water separator, and further, a structure in which the air whose water has been separated by the water-water separator is returned to the inside of the container body. Good.

Although the present invention is applied to the horizontally long heating container in the first and second embodiments and the heating container having the shape of a hollow pot in the third embodiment, the present invention is not limited to this and other embodiments are also applicable. Applicable to general shaped container bodies.

In all of Examples 1, 2 and 3 described above, the bottom of the container body has a double pot structure and steam is put therein to heat the bottom of the container body. However, the present invention is not limited to this. The bottom of the container body may not be formed into a double pot structure, but the bottom of the container body may be directly provided with an electric heating means or the like to heat the bottom.

In all of Examples 1, 2 and 3 above, superheated steam is introduced from the container body portion into the container body whose opening is closed by the lid. Of course, the structure may be such that superheated steam is introduced into the inside from the lid portion.

[0033]

As described in detail above, the present invention has the following effects.

Since the lid for closing the opening is provided, the inside of the heating container is in a sealed state, the heating temperature at the bottom of the heating container can be lowered, and therefore, the burning can be prevented. Moreover, since the opening is closed by the lid, the temperature rises quickly, and energy can be saved.

Due to the presence of the lid, hot air containing a large amount of steam or moisture generated when the food material is heated does not flow out from the opening of the container body, and the surrounding environment can be improved. If the lid is provided with a water outlet such as a drain port, the water droplets that have condensed on the inside of the lid can be discharged as water from the water outlet.

If a structure is provided with a circulation means for separating air containing water into an air component and a water component and returning the separated air to the inside of the container body again, the amount of water produced by the circulation means By measuring, it is possible to grasp the amount of water remaining inside the container body whose opening is blocked by the lid, and to determine the characteristics of food related to that water, such as viscosity, in the desired state. It is possible to make food with
