Description

  The present invention relates to an apparatus for boiling noodles such as Japanese soba, udon or Chinese soba.

  The apparatus for boiled noodles is composed of a boiled pan and a heating device provided below the boiled pan, and it is usual to put noodles in boiling water boiling by the heating device and boil it.

  When noodles are boiled, starch and protein dissolve in the hot water, so if you continue to boil the same hot water over and over again, the hot water will become cloudy and become hot water. In such a state, the boiling point of the hot water is lowered, and the hot water of low temperature is used to work with firewood, and the degree of alpha conversion of the noodles is only about 70 to 80%, so that it becomes boiled noodles like a half-life. . On the other hand, if the time is extended with boil until 100% alpha is achieved, the surface of the noodles will become rough and the noodles will not lose their waist.

  In addition, in the case of Chinese noodles, Kansui is used in the production of noodles, so if you continue to boil with the same hot water, the hot water will discolor and generate a foul odor, which will boil The noodles will have the color and smell.

Therefore, in restaurants, etc., by boiling out some or all of the boiling water in the pot from time to time and refilling the pot with hot water that has been warmed to some extent with tap water or a jacket (copper pot), etc., It is common to purify hot water with boiling water.

  It is desirable to continuously boil noodles at restaurants, etc. until busy time is over, but for that purpose continuous injection of clean water into the pan and continuous discharge of sewage from the drainage are the best methods. It is.

  However, if you pour purified water such as tap water directly at room temperature, boiling will stop and you will not be able to obtain good boiled noodles. However, it is practically impossible to continuously boil while continuously injecting clean water.

  In addition, the method of pumping hot water from the inside of the pot with a boil and replenishing the hot water in the jacket with the boil from time to time is not only forced to pause the boiled work while replacing part or all of the boiled hot water. Since the temperature of the hot water in the jacket is not sufficiently high, there is a problem that after the hot water has been replaced with boiling water, the operation must be stopped until boiling again.

  Therefore, using the exhaust gas from the heating device that heats the pan with firewood or the exhaust heat such as the hot water overflowing from the pan with firewood, preheated clean water at room temperature or hot water in the jacket is supplied to the pan with firewood. Various types have been developed. However, none of the conventional purified water preheating mechanisms using waste heat is said to have sufficient preheating efficiency, and the temperature of the injected purified water cannot be increased so much that boiling water is poured while continuously injecting purified water. There is a problem that it is difficult to achieve the purpose of continuous boiling.

  The present invention aims to solve the above-described conventional problems.

  FIG. 1 shows a first embodiment of the present invention. Reference numeral 1 denotes an inner pot which becomes a boiled pan, and in this example, the inner pot 1 is composed of a square pot which is substantially square in a plan view.

  The outer peripheral portion of the side wall of the inner pot 1 is surrounded by an outer pot 2 in which a jacket (copper rod) 3 is formed. Further, a drainage portion 11 is provided at the upper edge portion of the side wall of the inner pot 1 by a notch, and a side groove 4 that receives the discharged hot water overflowing from the drainage portion 11 has an upper outer periphery of the side wall of the inner pot 1. Is provided integrally or integrally with the inner pot 1. A discharge port 41 is provided at a predetermined position on the bottom surface of the side groove 4, and the hot water flowing out from the drainage part 11 flows through the side groove 4 and is discharged from the discharge port 41 to the outside. For example, the outlet 41 is located as far as possible from the drain 11 so that the hot water that overflows from the drain 11 and flows into the side groove 4 flows in the side groove 4 in a predetermined direction and is discharged from the outlet 41. Appropriate means are provided, such as providing a predetermined inclination on the bottom of the side groove, or providing an appropriate partition. Further, a weir 42 is appropriately provided in the side groove 4 around the discharge port 41, and the drainage flowing through the side groove 4 by the weir 42 always has a predetermined depth (the second heat exchange water passage 7 described later is submerged. To keep the depth). A second heat exchange water passage 7 is disposed in the side groove 4.

  A heating device 5 such as a gas burner is installed in the lower part of the inner pot 1, and hot water is heated and boiled in the inner pot 1 by combustion of the heating apparatus 5, and water in the jacket 3 of the outer pot 2 is drained. In the same manner, the combustion gas is discharged through the exhaust passage 21 provided in the outer pot 2 to the outside through the exhaust passage 21.

  The cross-sectional shape of the exhaust passage 21 is a horizontally long rectangular shape having a lateral width close to the width of the outer hook 2 as shown in the figure, and a first heat exchange water passage 6 to be described later in the exhaust passage 21. Are arranged sideways. One end of the first heat exchange water passage 6 is connected to a purified water supply pipe such as tap water through a cock C1, and the other end is connected to one end of the second heat exchange water passage 7. The other end of the second heat exchanging water passage 7 is connected to the jacket 3 of the outer pot 2 and passes through the first and second heat exchanging water passages 6 and 7 by exhaust heat and hot water. Heated warm water is supplied into the jacket 3.

  C2 is a cock for supplying purified water such as tap water into the jacket 3, and 8 is a hot water supply port for supplying hot water in the jacket 3 into the inner pot 1. The jacket 3 is in a sealed state, and if the jacket 3 is continuously supplied with purified water such as tap water, the water in the upper part of the jacket 3 (hot water) is heated by the purified water supply pressure after the jacket 3 is full. It flows out from the port 8 and is supplied into the inner pot 1. Although not shown, a drain cock is provided at the bottom of the inner hook 1 and the jacket 3 as usual.

  In the above, the first and second heat exchange water passages 6 and 7 have a structure in which a pipe material made of a metal having good heat conductivity such as aluminum, aluminum alloy, copper, copper alloy or the like is wound in a coil shape. And In the first heat exchange water passage 6, the coil wound and formed is disposed in the exhaust passage 21 in a direction in which the coil center line is perpendicular to the outflow direction of the combustion gas, that is, in the lateral direction. The second heat exchange water passage 7 has a structure in which it is wound in a coil shape and disposed in the side groove 4 in the direction along the coil center line along the flow of the hot water. It is desirable that the water in the second heat exchange water passage 7 is configured to flow in a direction opposite to the flow direction of the hot water in the side groove 4.

  In the illustrated embodiment, the first heat exchange water passage 6 is an example in which a pipe material is formed in a coil shape and arranged in two stages, upper and lower (or front and rear). However, the number is not limited to one, and may be one or may be arranged in three or more stages. Further, the second heat exchange water passage 7 is configured such that the coil diameter of the pipe material wound and formed in a coil shape is substantially the same as the width dimension of the side groove 4, and the coiled pipe material is disposed in the side groove 4. Although an example in which it is fitted and fixed over almost the entire circumference is shown, the arrangement structure of the coiled pipe material constituting the second heat exchange water passage 7 in the side groove 4 is not limited to the embodiment shown in the figure. The following configuration can be adopted.

  The operation of the apparatus configured as in the embodiment of FIG. 1 will be described below.

  First, the cocks C1 and C2 are opened at the start of work. Then, purified water is directly injected into the jacket 3 and simultaneously injected from the first heat exchange water passage 6 through the second heat exchange water passage 7 into the jacket 3. When the water in the jacket 3 is full, the water in the jacket 3 flows into the inner pot 1 from the hot water supply port 8, and when the water in the inner pot 1 is full, the cocks C1 and C2 are once closed. The heating device 5 is ignited at an appropriate time during the injection of the purified water (at the time when there is no risk of emptying), and when the water in the inner pot 1 has boiled, the operation starts with the noodle bowl.

  The water in the jacket 3 is also heated by the heating device 5 in substantially the same manner as the water in the inner pot 1, but the heating condition is different from that of the inner pot 1, so even if the water in the inner pot 1 becomes boiling, the jacket 3 The water inside does not easily boil or become nearly boiling. Therefore, the cocks C1 and C2 are closed for a while and then the work is carried out with a scissors, and the cock C1 is opened when the timing is reached (when the temperature of the purified water in the jacket 3 is about 70 ° C.). Then, clean hot water that has been effectively heated by the exhaust heat and the hot water from the cock C1 through the first and second heat exchange water passages 6 and 7 is continuously injected into the jacket 3, The upper hot water is continuously supplied from the hot water supply port 8 into the inner pot 1.

  In the above description, the purified water temperature supplied from the cock C1 through the first and second heat exchange water passages 6 and 7 into the jacket 3 is effectively heated by the exhaust heat and the exhaust heat, and is equal to or higher than a predetermined value (for example, 60 to 70 ° C.), the hot water temperature in the upper part of the jacket 3 (approximately 70 ° C. or higher) is not changed even if the supply into the jacket 3 is continued. Even if hot water in the upper part of the jacket 3 is continuously injected into the pot 1, there is no possibility that boiling of the hot water stops in the inner pot 1 and the purification capacity of the hot water in the inner pot 1 is greatly improved. Can be made.

  That is, when the cock C1 is opened and clean water at normal temperature flows through the first heat exchange water passage 6, it is warmed by the high-temperature combustion gas flowing in the exhaust passage 21 during that time to become hot water. In this case, since the first heat exchange water passage 6 is formed of a coiled pipe material and is disposed horizontally with respect to the combustion gas flow, the contact efficiency with the combustion gas is very good, and the heat The exchange efficiency is the best, and the hot water when it flows out of the first heat exchange water passage 6 and flows into the second heat exchange water passage 7 has a considerably high temperature.

  While the hot water flowing out from the first heat exchange water passage 6 flows through the second heat exchange water passage 7, it is further added by the drained water (temperature close to the boiling state) that overflows the drainage section 11 and flows through the side groove 4. After being heated, it is supplied into the jacket 3. In this case, the second heat exchange water passage 7 is made of a coiled pipe material, and the depth of the hot water flowing in the side groove 4 is the same as the coil diameter of the coiled pipe material by the weir 42. Since it is kept slightly deeper, both the contact area and the contact time with the hot water are large, the heat exchange efficiency is extremely good, and the hot water temperature supplied into the jacket 3 from the second heat exchange water passage 7 Is almost the same as the water temperature in the jacket 3 and does not change the high temperature state in the upper part of the jacket 3 even if it is continuously supplied, and boiling of the hot water from the hot water inlet 8 into the inner pot 1 It can be kept at a high temperature that does not stop, and it is possible to achieve the purpose of continuously purifying the noodles for a long time while purifying the boiling water by continuously supplying clean hot water. .

  The inner pot 1 has a volume of 50 to 70 liters and the jacket 3 has a volume of 40 to 50 liters and is supplied into the jacket 3 from the first and second heat exchange water passages 6 and 7 made of coiled pipe material. As a result of conducting various experiments at a water volume of 1 to 2 liters per minute, it takes about 20 to 25 minutes for the tap water having a temperature of 5 ° C. injected into the inner pot 1 to reach a boiling state. The water in the jacket 3 (also 5 ° C. water) varies depending on the structure of the outer pot 2, but reaches about 70 ° C. when the water in the inner pot 1 reaches a boiling state. Will also be in a state of boiling or near boiling. Further, the tap water of 5 ° C. is heated by the combustion gas heat while passing through the first heat exchange water passage 6 and becomes approximately 32 ° C., and this is passed through the second groove 4 while passing through the second heat exchange water passage 7. It was confirmed that it was further heated by flowing hot water to become hot water of approximately 62 ° C. The tap water at 5 ° C. is, for example, the tap water temperature at the coldest time of the winter in the Tokyo region, and at other times the tap water temperature is at least about 15 to 25 ° C. The water passing through the replacement water passages 6 and 7 is expected to be 70 ° C. or higher.

  FIG. 2 shows a second embodiment of the present invention. In FIG. 1, the inner pot 1 serving as a boiled pan is composed of a square pot having a substantially square shape in plan view, whereas in FIG. 1 is different from that shown in FIG. 1 except that it is formed of a so-called round pan having a circular shape in plan view, and the other configurations are almost the same as those in FIG. 1, and the operations and effects are the same as those in FIG. 2, the same reference numerals as those in FIG. 1 represent the same parts as those in FIG.

  When the inner pot 1 is a square pan as shown in FIG. 1, the inner pot 1 generally has a fixed structure, and therefore, a hot water supply port 8 for supplying hot water from the jacket 3 to the inner pot 1 is shown in FIG. It has a fixed structure. However, when the inner pot 1 is a round pan as shown in FIG. 2, it is common to remove the inner pot 1 so that the inside can be cleaned. Therefore, in the case of FIG. 2, the hot water supply port 8 for supplying hot water from the jacket 3 to the inner pot 1 is constituted by a faucet capable of swinging. However, even if it is a round pan, when it has a fixed structure, the hot water supply port 8 may have the same fixed structure as in FIG. 1, or even if the inner pot 1 has a fixed structure as shown in FIG. You may comprise 8 with the faucet which can be swung.

  In the embodiment shown in FIGS. 1 and 2, the hot water that has passed through the first heat exchange water passage 6 formed by arranging the coiled pipe materials in two upper and lower stages is the second heat exchange water passage 7. However, the hot water heated by the exhaust heat through either one of the upper and lower stages of the first heat exchange water passage 6 is supplied to the second heat exchange water passage 7. After entering and flowing through the second heat exchange water passage 7 and being heated by the exhaust hot water, it flows into the other stage of the first heat exchange water passage 6 and is heated again by the exhaust heat to be jacketed. The connection order and connection combination of the first heat exchange water passage 6 and the second heat exchange water passage 7 may be arbitrarily selected without being limited to the illustrated embodiment. .

  FIG. 3 shows a third embodiment of the present invention. That is, in the embodiment of FIGS. 1 and 2, hot water that has passed through the first and second heat exchange water passages 6, 7 is supplied into the jacket 3, and hot water in the upper portion of the jacket 3 is supplied from the hot water supply port 8 to the inner pot 1. 3, the exhaust gas flowing in the exhaust passage 21 through the first and second heat exchange water passages 6, 7 made of a coiled pipe material and the exhaust gas flowing in the side groove 4 are configured. There are provided two cocks C3 and C4 for branching the hot water heated with hot water into a path for supplying the jacket 3 to the jacket 3 and a path for supplying the hot water directly into the inner pot 1, and switching between the two paths. Direct hot water supply for supplying hot water heated in the first and second heat exchange water passages 6 and 7 directly into the inner pot 1 in addition to the hot water supply port 8 for supplying hot water in the upper part of the jacket 3 into the inner pot 1 A mouth 80 is provided. Other configurations are the same as those in FIGS. 1 and 2, and the same reference numerals as those in FIGS. 1 and 2 represent the same parts as those in FIGS. In FIG. 3, for easy understanding, the outer hook 2 surrounding the outer periphery of the inner hook 1 is divided into two parts on the left and right sides, and provided so as to surround the outer periphery of the upper side wall of the inner hook 1. The side groove 4 is shown as being developed on one side of the inner hook 1, but actually has the same structure as FIGS. Further, in the embodiment of FIG. 3 as well, as in the embodiment of FIGS. 1 and 2, the number of stages of the coiled pipe material constituting the first heat exchange water passage 6 and the side groove of the second heat exchange water passage 7 are the same. The arrangement structure in 4, the connection order and the connection combination of the first heat exchange water passage 6 and the second heat exchange water passage 7 can be arbitrarily selected without being limited to the illustrated embodiment.

  An example of use of this FIG. 3 will be described below.

  First, at the time of water injection, only the cock C2 is opened and C1, C3, and C4 are closed, and purified water such as tap water is supplied into the jacket 3. Since the jacket 3 is a sealed type, when the jacket 3 is full, water is poured from the hot water supply port 8 into the inner pot 1. When the water in the inner pot 1 has been halved (where there is no risk of emptying), the heating device 5 is ignited, the cocks C2 and C3 are closed, C1 and C4 are opened, The water is supplied directly from the hot water supply port 80 into the inner pot 1 through the first and second heat exchange water passages 6 and 7. Then, while passing through the first heat exchange water passage 6, hot water heated by the combustion gas heat of the heating device 5 is injected into the inner pot 1, thereby increasing the initial water temperature of the inner pot 1 and causing boiling. The time until is greatly shortened.

  When the water in the inner pot 1 is full, only the cock C4 is opened and all the other cocks are closed, and this state is continued until the water in the inner pot 1 is boiled. Meanwhile, steam generated in the jacket 3 is discharged from the hot water supply port 8 and steam generated in the first and second heat exchange water passages 6 and 7 is directly discharged from the hot water supply port 80 through the cock C4.

  When the inside of the inner pot 1 is in a boiling state, the operation starts with the noodle soup. At this time, the cocks C1 and C4 are opened, and C2 and C3 are closed. Then, hot water heated through the first and second heat exchange water passages 6 and 7 is continuously supplied directly into the inner pot 1 from the hot water supply port 80. The hot water temperature heated in the first and second heat exchange water passages 6 and 7 is at least about 60 to 70 ° C. as described above, and there is no fear that boiling of boiling water will stop, and the old Boiled hot water overflows from the drainage part 11 to the side groove 4 and is continuously discharged, so that the continuous purification of the hot water in the inner pot 1 is performed.

  When the water in the inner pot 1 starts to boil, the warm water in the jacket 3 is about 70 ° C, but after a while after starting the boil work, the warm water temperature in the jacket 3 becomes about 70-80 ° C. At an appropriate time, the cocks C1 and C3 are opened, C2 and C4 are closed, and hot water heated in the first and second heat exchange water passages 6 and 7 is supplied into the jacket 3, The upper hot water of 70 to 80 ° C. or higher is continuously supplied from the hot water inlet 8 into the inner pot 1. Further, after the temperature of the hot water in the jacket 3 has risen to a state close to boiling, in some cases, the cocks C1, C2, and C3 are opened and only C4 is closed, and the first and second heat exchange water passages 6 and 7 are closed. A large amount of hot water in the upper part of the jacket 3 is maintained in such a state that clean hot water heated through the pipe 3 continues to be injected into the jacket 3 and low-temperature (room temperature) purified water continues to be injected directly into the jacket 3 from the cock C2. It can also be set as the state which is continuously supplied from the hot-water supply port 8 into the inner pot 1.

  According to the embodiment of FIG. 3, in addition to the same operations and effects as in FIGS. 1 and 2, it can be used in various ways according to the situation as described above, so that the benefit can be greatly improved. it can.

FIG. 4 shows a fourth embodiment according to a reference example of the present invention, and this example is intended for an apparatus using a noodle jar having no jacket (copper jar).

  In FIG. 4, instead of the outer hook 2 of the embodiment of FIGS. 1 to 3, the outer casing 20 in which a heat insulating material is stretched is used, and the outer peripheral portion of the side wall of the inner pot 1 is surrounded by the outer casing 20. It does not have a jacket. Other configurations, that is, a drainage portion 11 is provided by a notch in the upper edge portion of the side wall of the inner pot 1, and a side groove 4 for receiving the hot water overflowing from the drainage portion 11 is provided on the outer periphery of the upper side wall of the inner pot 1. In addition, the hot water overflowed from the drainage part 11 flows in the side groove 4 in a predetermined direction and is discharged to the outside from the discharge port, and the periphery of the discharge port so that the hot water flowing in the side groove 4 maintains a predetermined depth. A heating device 5 such as a gas burner is provided in the lower part of the inner pot 1, and the combustion gas (exhaust gas) is exhausted to the outside through the exhaust passage 21. Is the same as that of the embodiment of FIGS.

  Further, in FIG. 4, first heat exchange water passages 6 formed by winding a pipe material in a coil shape in the exhaust passage 21 are arranged in multiple stages in a lateral direction, and the pipe material is also coiled in the side groove 4. A second heat exchange water passage 7 formed by winding is provided, and one end of the first heat exchange water passage 6 is connected to a purified water supply pipe such as tap water via a cock C1, and the other end. 1 is connected to one end of the second heat exchange water passage 7 as in the embodiment of FIGS. 1 to 3, but the other end of the second heat exchange water passage 7 is directly fed into the inner pot 1 with hot water. The hot water heated by the exhaust gas and the hot water while flowing through the first and second heat exchanging water passages 6 and 7 is continuously connected to the inner pot 1 from the direct hot water outlet 80. The point which becomes the structure supplied with hot water differs from the Example of the said FIGS.

  In the example of FIG. 4, the exhaust gas has a higher temperature than in the case of FIGS. 1 to 3 because the heat in the jacket is not deprived of heat, and therefore is due to the exhaust gas heat in the first heat exchange water passage 6. Since the preheating effect is better than in the case of FIGS. 1 to 3, the temperature of the hot water directly supplied to the inner pot 1 from the direct hot water supply port 80 is at least 70 ° C. or higher. There is no fear of stopping boiling of hot water in the boiling water in 1 and the purification function of boiling water can be improved.

1 to 4 show an example in which the first heat exchange water passage 6 is disposed in the outer passage 2 or the exhaust passage 21 of the outer casing 20, but the present invention is not limited to this configuration. .
That is, the exhaust passage referred to in the present invention includes a general chimney. That is, in this invention, it is good also as a structure which formed the enlarged diameter part in a part of normal chimney generally used, for example, and has arrange | positioned the 1st heat exchange water channel 6 sideways in it.

  Furthermore, in each Example of FIGS. 1-4, although the example which formed the drainage part 11 by partially notching the upper edge of the side wall of the inner pot 1 is shown, the structural means of the drainage part 11 is partly notched. Not limited to, for example, the upper edge of the inner hook 1 is inclined so that the specific position (lowest place) of the upper edge is used as the drainage section 11. As the drainage section 11, the boiling water overflows from the specific position of the upper edge of the inner pot. Any configuration that can achieve the above-described purpose can be adopted.

  FIG. 5 shows another example of the second heat exchange water passage 7 used in FIGS.

  That is, in FIG. 5, side grooves 4 having a substantially quadrilateral shape in plan view are formed so as to surround the inner hook 1, and the pipe material is bent zigzag so as to reciprocate a plurality of times in the longitudinal direction for each side of the side grooves 4. The molded product is connected at the corner of the side groove to form the second heat exchange water passage 7, and one end 7 a of the second heat exchange water passage 7 is connected to the outlet of the first heat exchange water passage 6. At the same time, the other end 7b is connected to the jacket 3 or the direct hot water supply port 80, and purified water (hot water) heated by the exhaust heat of the combustion gas while passing through the first heat exchange water passage 6 is second from 7a.
