Description of the invention: (1) Technical field to which the invention belongs The present invention relates to a food heating device, particularly a food heating device that sprays steam on food for rapid heating. (2) Prior art Since the past, a food heating device that rapidly heats foods by spraying steam from the nozzles is well known, as shown in FIG. 6 (Patent Document 1). Fig. 100 shows a ravioli heating device. The heating device 100 includes a mounting portion 101, and the mounting portion 101 is formed as a storage container 103 for storing food such as simmered food 102 (for example, liquid such as lamb soup). A lid 104 covering the container 103 is provided above the storage container 103. The lid 104 is provided with a nozzle 105 for injecting steam, and a temperature sensor 106 for detecting the temperature of the foodstuff 102. When the food heating device 100 as described above is pushed down by the rod 107, the lid 104 covers the storage container 103 placed below, and the nozzle 105 and the temperature sensor 106 are inserted into the food 102 . Then, the food and beverage 102 was heated by vapor formation in this state. When the cover 104, the nozzle 10, and the temperature sensor 106 need to be cleaned in order to heat the food of a different kind of rice, the cleaning means 1 0 8 provided on the mounting portion 10 is moved to the cover. The body 104 is directly below the body 104, and then the cover body 104 is moved below in this state, and steam or water sprayed from the means 108 is used to form the cover body 104 and the like. (Patent Document 1) Japanese Patent Application Laid-Open No. 2003-70644 (Page 1, Figure 1) 200522905 (3) Summary of the Invention (Problems to be Solved by the Invention) ~ However, in the above-mentioned food heating device 100, The lid 104 serves as the storage container 103 and is heated in a substantially closed state by steam spraying. Therefore, the internal pressure of the storage container 103 is excessively increased, and there is a concern that the food and beverage 100 may overflow from the container 103. The nozzle 105 was inserted into the foodstuff 102 as a steam jet. Therefore, when the steam side of the nozzle is suddenly depressurized when the steam jetting is stopped, the food and beverage 102 may flow back into the nozzle 105. Since the nozzle 105 and the temperature sensor 106 are close to each other, the vapor sprayed from the nozzle 丨 05 directly touches the temperature sensor 106, and it also becomes impossible to detect the food 1 correctly. 〇 2 temperature considerations.尙 Enlarge the gap between the nozzle 105 and the temperature sensor 丨 〇6 When inserting the temperature sensor 106 into the 飮 food 〇2, it is difficult to avoid the temperature error due to the steam injection. Increasing the above-mentioned interval may cause a cover body and a large device as a whole. Furthermore, as in the above-mentioned ravioli food heating device 100, whenever a different kind of ravioli food is to be heated, the cover body 1 〇4, the nozzle 105, and the temperature sensor are cleaned by washing means 〇8.丨 06, etc., there is a concern that the workability of heating is reduced. It was also checked that the fl # girl had frequent concerns about the management of the cow's face during the washing. The object of the present invention is to “provide that the internal pressure of the container can be prevented from increasing excessively during heating”, and that the food backflows when the steam jet is stopped. Furthermore, by accurately grasping the temperature of one person, the food can be heated quickly and efficiently Moreover, it can also provide commercial food heating devices such as heating workability. 200522905 (Means to solve the problem) In order to solve the above-mentioned problem, the ravioli food heating device of the present invention is a ravioli food heat treatment device that injects steam from a mussel mouth into a ravioli cup filled with ravioli to heat ravioli. It is characterized in that it is provided with a cover body that covers the food cup while heating, and has a pressure adjustment means that is formed as the front end of the nozzle front end and the internal pressure of the food cup, and a control means that controls the steam ejection from the nozzle. Made. The term "heating" as used in this specification is not only for raising the temperature of food, but also for those who want to prepare food and drink by heating. It is desirable that the above-mentioned cover system be provided in plural in one device. If a plurality of lids are provided and the food corresponding to this is fixed, washing time and labor can be largely omitted. It is desirable to provide a backflow prevention valve at the nozzle. By providing a backflow prevention valve, it is possible to reliably prevent the backflow to the food nozzle side when the vapor injection that the previous device was worried about stops. The ravioli heating apparatus of the present invention is preferably provided with a mounting table on which the ravioli cup is placed. If such a mounting table is provided, it is possible to reliably prevent the position shift of the food cup during steam injection during heating. It is also preferable that a temperature detecting means for detecting the surface temperature of the food cup and / or the ambient temperature around the cup is provided on the mounting table. According to the above detection and surface temperature and ambient temperature, the actual temperature of the food can be accurately grasped. Since the temperature detection means is located outside the food and beverage cup, it is not affected by the steam jet. It is not necessary to wash every kind of food. In addition, the temperature detected by the temperature detection means is fed back to the control means such as 200522905 steam injection, so that the food can be quickly and reliably added to the target heating temperature. The control means described above is ideally connected to a setting means that can input a set target heating temperature or the thermal conductivity of various food and beverage and food cups, such as the heat dissipation of food cups. Then, the actual heating time can also be calculated automatically by using the temperature detected by the input data and temperature detection means. In addition, if necessary information such as the target heating temperature is input in advance in the setting means, the temperature of the food can be reliably heated even when the temperature measurement of the food is omitted. For example, frozen products are usually frozen to 0 to 5 t. Therefore, by using necessary information such as the initial temperature and the target heating temperature, it is not necessary to omit the temperature detection of the food, and it can be heated to the target heating temperature. In order to solve the above problem, the ravioli food heating container of the present invention is characterized by a ravioli food cup filled with ravioli and a front end sound 13 having a nozzle tip covering the ravioli food while spraying steam into the ravioli food cup. It is made by a lid body that adjusts the pressure inside the food cup. In addition, in order to solve the above-mentioned problem, the lid body of the ravioli food container according to the present invention is characterized by having a ravioli food cup that is filled with ravioli, and simultaneously forming a front end of a nozzle tip that ejects steam into the ravioli food cup and The pressure adjustment means for adjusting the pressure of the food cup. When the food container and its cover are as described above, time and labor for cleaning the cover and the like can be omitted, and the heating operation and the management of the sanitary surface can be efficiently performed. (4) Embodiment (The embodiment of the invention) 200522905 Hereinafter, preferred embodiments of the food and beverage heating device and the food container according to the present invention will be described with reference to the drawings. Fig. 1 shows a food and beverage heating apparatus according to a first embodiment of the present invention. Fig. 1 shows a ravioli food heating device. The food heating device 1 includes a mounting table 4 on which a food cup 3 filled with food 2 is placed. The food 2 filled in the cup 3 may be any food or food that can be heated, and may be any liquid and fixed. A cover 5 is provided to cover the food cup 3 above the mounting table 4. The lid body 5 is formed to be fitted into the food cup 3, and the food and beverage cup 3 is hermetically sealed by the lid body 5. The lid 5 is provided with a steam generating means 13 (e.g., a boiler) that sprays steam into the food cup 3 to form a front end portion 7 at the front end of the nozzle 6. The distal end portion 7 is inserted into the food or drink 2. The nozzle 6 is more specifically provided with a backflow prevention valve 12 at a front end portion 7 thereof. Therefore, a sudden decompression of the inside of the nozzle 6 can surely prevent a defect such as the food and beverage 2 from flowing back to the nozzle 6 side. In addition, the lid body 5 is provided with a pressure adjusting means 8 in the food cup 3 according to the fact that the lid body 5 is sealed in a substantially air-tight state. In this embodiment, the pressure adjusting means 8 uses a pressure valve, but it is also possible to form one or a plurality of pores in the lid to prevent excessive pressure rise in the food and beverage cup 3. In addition, according to the pressure adjustment means 8, the pressure in the food cup 3 is adjusted to be moderate during the steam injection, so that it is possible to surely prevent the unfavorable situation such as overflowing the food cup 2. The mounting table 4 is provided with a temperature detecting means 9 for detecting the surface temperature of the food cup 3. The temperature detected by the temperature detection means 9 is fed back to the control means 10, and according to the control means 10, it becomes the control of the steam evacuation from the steam generation means 13 by the 200522905 gas. In the present embodiment, although the surface temperature of the food cup 3 is detected according to the temperature detecting means 9, it is also possible to detect both the ambient temperature around the cup 3 and the surface temperature and the ambient temperature.尙 Temperature detection means 9 is not for directly detecting the temperature of 飮 Food 2, but the thermal conductivity of 飮 Food 2 'Cup 3, the initial temperature of 飮 Food 2, and the heat dissipation amount from Cup 3 are input in advance to the setting means 1 1 described later. 'Then according to the temperature detection means 9 from the detected temperature and the above-mentioned preset input data, the control means 10 can accurately grasp the actual temperature of the food 2. Also unlike the previous device, the temperature detecting means 9 is not affected by the vapor ejection from the nozzle 6. Therefore, in contrast to the case where the temperature sensor is directly inserted into the food 2, the temperature can be accurately detected. The control means 10 has setting means for inputting various data such as heat conductivity of foods and drinks 2, cups 3, and the like, target heating temperature and heating time of each food, and the like. In addition, the control means 10 is formed by automatically calculating the actual heating time from the various data set in advance and the temperature detected by the temperature detection means 9. In the ravioli food heating device 1 of the present embodiment, the lid body 5 is provided with a pressure adjusting means 8. Therefore, an excessive increase in the pressure in the cup 3 during steam injection can be prevented, and problems such as overflowing of ravioli food 2 can be prevented. The nozzle 6 is provided with a backflow prevention valve 12, so that when the steam injection is stopped, the inside of the front end portion 7 is suddenly depressurized, and the foodstuff 2 can be prevented from flowing back to the nozzle 6 side. Also in this embodiment, the temperature detecting means 9 is provided outside the food cup 3, so the steam sprayed from the nozzle does not directly touch the temperature detecting means 9 °, so that the surface temperature of the cup 3 can be accurately detected. In addition, the data of 飮 Food 2 -10- 200522905, the thermal conductivity of Cup 3, and the amount of heat dissipated from Cup 3 are input in advance, and the temperature of 飮 Food 2 can be accurately grasped based on the above-mentioned detection temperature and data. In Fig. 1, a cover 5 is shown. However, as shown in Fig. 2, a plurality of covers 5 can be provided in the middle of the branching nozzle 6. In this case, fixing the cover 5 with each kind of foodstuff can reduce the number of washing times, so that the heating operation and the management of the sanitary surface can be efficiently performed. Fig. 3 shows a baked food heating device 14 according to a second embodiment of the present invention.相同 The same components as in the first embodiment described above will be omitted with the same reference numbers. In this embodiment, the heating time is input in advance in the setting means i i, and it is formed so that the temperature of the food 2 is not detected and heated. Generally, due to heat conduction to the cup 3 or heat radiation to the outside, a deviation between the calculated caloric value of the caloric value given to the food 2 with a certain amount of steam (ml) and the actual measured value. The more the amount of steam increases, the larger the deviation between calculated and measured radon. This is due to the increase in the amount of steam also increases the amount of heat to the part. However, 'the object of 160ml before and after the food volume of one person who has become mainstream now is the object', and the deviation between the measured and calculated values is approximately constant as shown in FIG. 4. Therefore, for example, if the initial temperature of the frozen food can be grasped, the temperature detection means 9 is omitted and only the heating time is controlled, that is, the target food temperature can be accurately heated. Also in this embodiment, the effects of the first embodiment described above are allowed. (9 is to prevent the food 2 from overflowing during heating or the food 2 from flowing back when the steam injection is stopped. FIG. 5 shows an implementation of the present invention. Food container and its lid. Food and beverage container 15 'has a food cup 1 7 -11-200522905 filled with food and beverage 丨 6, and the lid 18 of the food and beverage container. The lid 18 is connected to spray A steam nozzle (not shown) is provided with a front end portion 19 forming a part of the nozzle. The front end portion 19 is provided with a backflow prevention valve 20. The cover body 18 is provided with a pressure adjustment for adjusting the pressure in the cup 17 Means 2 1 (for example, a pressure valve formed by a reed valve) ο The food container 1 5 ′ in this embodiment is provided with a pressure adjusting means 21 in the cover 18, so it is prevented during steam injection The excessive increase in the internal pressure of the cup 17 can prevent the problems such as overflowing and food 16. Also, a backflow prevention valve 20 is provided at the front end portion 19 forming the front end of the nozzle, so when the steam injection is stopped, the nozzle side is suddenly decompressed. It can also prevent the back food 16 from flowing back to the nozzle side. The same situation with the cover on the heating device side is for the seller to integrate the cup 17-so it is not necessary to wash the cover 18 during heating, so it can efficiently manage heating operations and sanitary noodles. ADVANTAGE OF THE INVENTION As mentioned above, according to the 加热 food heating apparatus, 飮 food container, and its cover of the present invention, while preventing the 飮 food from overflowing during heating, or the 飮 food from flowing back reliably during steam injection, Moreover, since the temperature of food and beverage can be accurately grasped to realize rapid and efficient heating, and it is not necessary to provide a cover on the side of the heating device, the heating workability can be improved, and the management of hygienic noodles can be performed efficiently.
