JP 2010-181417 A

  In the above application, the hydrogen gas burner main body for preventing backfire has been studied, but application to a grill or an oven has not been studied, and the ignition means for that purpose has not been disclosed. There is not enough disclosure about how to cook food.

  The hydrogen cooking method according to the first invention of the present invention is to burn hydrogen into steam, and cook vegetables such as chicken, pork, bread and eringi, leek, pumpkin, sweet potato in the oven with hot air containing this steam, Chicken was maintained at a water loss rate of 15% or less, pork 18% or less, bread 8% or less, and vegetables 15% or less.

  Also, the hydrogen cooking method according to the second invention of the present invention is such that hydrogen is used as a flame, and the fish is cooked while maintaining a water loss rate of 15% or less in a griller that is exposed to this flame from above. I made it.

And a hydrogen water production device for dissolving hydrogen gas from a hydrogen supply source in water and preventing backfire from the hydrogen cooking device. This hydrogen water production device comprises a hydrogen water tank The hydrogen gas is supplied to the hydrogen cooking device through the water in the hydrogen water tank.

  In addition, the hydrogen water production apparatus includes a hydrogen water tank for storing water, a bubble generating member disposed in the hydrogen water tank for generating bubbles, and supplying hydrogen to the bubble generating member. It is preferable to include a hydrogen supply line and a hydrogen discharge line that discharges hydrogen accumulated in the upper space of the water tank to the outside.

  Furthermore, a hydrogen cooking device according to a fourth aspect of the present invention is a box-shaped main body casing, a combustion body disposed in the main body casing and combusting with hydrogen, and food is placed corresponding to the combustion body. The combustion body is provided with an automatic ignition device for igniting hydrogen gas, and the automatic ignition device is adjacent to the nozzle at the base of the burner in a system in which hydrogen is sent to the burner. The ignition element was provided, and the diameter of the burner nozzle was set to 0.1 mm to 0.5 mm.

  The hydrogen water production apparatus according to the fifth aspect of the present invention includes a hydrogen water tank for generating hydrogen bubbles to dissolve hydrogen in water, a drinking water tank for storing drinking water, A bubble generator provided in the hydrogen water tank for generating hydrogen bubbles; a hydrogen source for storing hydrogen; an accumulator for storing hydrogen to be supplied to the bubble generator; and A circulation pump that is provided in the accumulator and sucks out the hydrogen in the accumulator and discharges it to the valve generator. The hydrogen from the valve generator rises in the water in the hydrogen water tank and is From the hydrogen tank to the circulation system along with the consumption of hydrogen, and the drinking water tank with the consumption of hydrogen water in the hydrogen tank Drinking water is adapted to be fed into the hydrogen water tank by the pressure of hydrogen supplied from the hydrogen source.

  According to a sixth aspect of the present invention, there is provided a method for producing hydrogen water, wherein a bubble generator for generating hydrogen bubbles is provided at the bottom of a sealed water tank, and the bubble rises from the bubble generator. A flow of water is generated, this water flow is changed horizontally in the vicinity of the liquid level, and further convection is generated as a downward flow. Hydrogen that has not dissolved in water is taken out from the upper space of the water tank and circulated. The pump was sent again to the bubble generator.

  The hydrogen oven heats the chicken, pork, and vegetables in the sealed space with hot air containing water vapor without escaping the moisture, so that the heat is transmitted to the center of the food in a short time and the water loss rate can be kept low. It is possible to effectively prevent the food from becoming hard after cooking. Note that when heated with a hydrogen flame, the fish's skin is burnt and prevents moisture from evaporating, so it is better to cook with a griller than an oven.

Since it is treated, hydrogen does not vaporize immediately even if it is poured into a cup from a hydrogen water tank. Moreover, since the drinking water from the drinking water tank is supplied to the hydrogen water tank at a pressure of 10 atm or less of the hydrogen source, it is not necessary to provide a water supply pump.

  Furthermore, if the hydrogen water tank is formed of a transparent material such as acrylic, bubbles can be visually recognized from the outside, and it can be confirmed that hydrogen is reliably dissolved in water. In addition, if the water pipe tip from the drinking water tank is positioned at the bottom of the hydrogen water tank, the pipe tip will be open when the water in the hydrogen water tank is reduced, and hydrogen will flow back into the drinking water tank. There is no.

  Furthermore, if the hydrogen source is a solid hydrogen source, a large amount of hydrogen can be stored, which makes maintenance easier.

  Dissolving hydrogen in water using a circulating bubble system can be dissolved in 1 ppm or more for about 30 minutes even if there is little hydrogen gas consumed, and even if stored in ordinary PET bottles, the concentration will decrease over a long period of time. There is nothing to do.

  As a cooking device that uses hydrogen as a heat source, a hot burner containing steam is created with a hydrogen burner, and an oven that cooks with this hot air and a flamer that creates a flame with a hydrogen burner and applies this flame to food from above, on the contrary, downward A stove with a hydrogen burner placed on the flame and food on the flame can be considered. Therefore, the water loss rate was measured when chicken (peach meat), pork, bread, eringi, leek, pumpkin and sweet potato were cooked to the extent that they could be eaten in a hydrogen oven. The results are shown in Table 1.

  In addition, although oil content flows out about meat, only the amount of water | moisture content which evaporated was assumed that this oil content was received in the tray and the oil content did not flow away.

これによれは、食することができる迄火を通すには、鶏肉は１４％以下、豚肉は１８％以下、パンは８％以下、野菜は１５％以下に失水率を維持するように調理するようにすることが好ましい。

A range is desirable.

  Next, a portable hydrogen water production apparatus combined in one unit will be described.

In FIG. 9, the hydrogen water production apparatus 200 has a hydrogen water tank 201 in which hydrogen water is produced, and this hydrogen water tank 201 includes a cylindrical casing 202 made of transparent polyurethane, and this casing 202 is placed on a table 203. The illuminating device 204 is accommodated in the table 203, and the illumination irradiates hydrogen water in the casing 202 through the transparent bottom plate 202 a of the casing 202. A bubble generator 205 is provided at the bottom of the casing 202. Hydrogen flows out of the bubble generator 205 and the hydrogen bubble b continuously rises in water. A faucet 206 is provided on the bottom side wall of the casing 202, and a water purifier 400 is attached to the faucet 206, from which hydrogen water is poured into a cup. A hydrogen pipe 207 is connected to the bubble generator 205, and this hydrogen pipe 207 is connected to a hydrogen system path ₁₅ , this hydrogen system path ₁₅ is connected to a circulation pump 208, and this circulation pump 208 is connected to hydrogen gas The circulation pump 208 has a suction port 210, and hydrogen gas sucked from the suction port 210 passes through the hydrogen system ₁₅ and the hydrogen pipe 207. To the bubble generator 205. The hydrogen gas flowing away from the bubble generator 205 rises in the water as a bubble, partially dissolves in water, accumulates in the upper space of the casing 202, and is attached to the top plate 202b of the casing 202. return to accumulator 209 through l ₆ , and these accumulators 20
9. The hydrogen system path ₅ , the bubble generator 205, the water in the casing, the upper space S _1, and the hydrogen system path ₆ form a hydrogen circulation system path.

これによれば、このバルブの循環方式によれば、３０分以上経過すれば、約１ｐｐｍの濃度となり、限界(上限）が１．１２〜１．１５の範囲であることが判明した。 The hydrogen generated from the bubble generator 205 forms inverted frustoconical bubble cylinders B and C, and the water in the bubble cylinders B and C is pushed up by the bubble b to generate an upward flow and rises above the liquid level. The water flows horizontally, spreads up to the inner wall of the cylindrical casing 202, then descends along the inner wall and causes convection to flow into the lower ends of the bubble cylinders B and C at the bottom of the casing, and to the entire inside of the casing. Hydrogen is uniformly dissolved (arrow A). The dissolved hydrogen concentration in the case of convection in this way increases with the elapsed time from the start of hydrogen circulation, and the experimental results at that time are shown in Table 4. The inner diameter of the casing 202 is 23 cm, the height of the injected water is 40 cm, the water volume is 16.6 l, the liquid surface diameter C of the bubble cylinders B and C is about 10 cm, and the hydrogen pressure in the system is 1.5. It was atmospheric pressure. Under these conditions, hydrogen water was collected from the faucet 206 at intervals of 2 minutes and 30 seconds, and the dissolved hydrogen concentration was measured.

According to this, according to this valve circulation system, after 30 minutes or more, the concentration became about 1 ppm, and the limit (upper limit) was found to be in the range of 1.12 to 1.15.

この結果、通常のＰＥＴに水素水を注入しても4日間は水素が抜けることがない。なお、３日間において、日の経過とともに濃度が上昇するのは、ペットボトル内の初期に入っていた小さなバブルが上昇して、蓋付近の水素濃度が上昇するためと思われる。 In addition, even when hydrogen dissolved in this way is put in a normal PET bottle, it has been found that 1 ppm can be maintained for 4 days when the lid of the PET bottle is closed, and the experimental results at that time are shown in Table 5. . In this case, hydrogen water having a concentration of 1 ppm or more was poured into 10 PET bottles, the lids were closed, one lid was opened at a time, and the concentration of hydrogen water was measured.

As a result, even if hydrogen water is injected into normal PET, hydrogen does not escape for 4 days. Note that the increase in concentration over the course of three days seems to be due to the increase in the concentration of hydrogen in the vicinity of the lid due to the increase of small bubbles in the PET bottle.

  Next, a hydrogen water production apparatus for producing hydrogen water by dissolving hydrogen in a large amount of water will be described.

  In FIG. 12, bubble generators 301,... 301 are provided at predetermined intervals at the bottom of the sealed water tank 300, and the bubble generator 301 is connected to a hydrogen pipe 302. Together with the hydrogen discharge pipe 303 and the circulation pump 304 provided on the upper surface of the water tank, a hydrogen circulation system path is constituted. Bubble cylinders B and C are formed in an inverted conical shape from the bubble generator 301, and the bubble generator 301 is spaced from each other so that the liquid surface diameters D of the bubble cylinders B and C do not overlap each other. The convection F, F... F is generated around each bubble cylinder B, C. That is, in the central bubble cylinders B and C, the water in the bubble cylinders B and C rises with the bubbles and flows laterally in the vicinity of the liquid level, and this flow is the liquid level of the bubble cylinders B and C on both sides. It collides with the lateral flow in the vicinity and flows downward. At the bottom of each bubble cylinder B, C, it is drawn into the bubble cylinders B, C and rises again. In the bubble cylinders B and C on both sides, a part of the flow descends along the inner wall of the water tank 300 and is drawn into the bottom of each bubble cylinder B and C. Thus, if water is convected by bubbles containing hydrogen, hydrogen is dissolved in the average water, and the concentration of hydrogen water is almost the same regardless of where the hydrogen water is collected from any position in the water tank.

On the other hand, as the hydrogen is consumed, hydrogen is supplied from the hydrogen tank 220 as a hydrogen source to the accumulator 209 through the regulator 221 and the valve 222 provided in the hydrogen system l ₇ . The hydrogen from the hydrogen tank 220 is also supplied to the upper space S ₂ of the drinking water tank 230 (water supply means) via the valve 231, and the drinking water ( Tap water) is supplied through a valve 233. Water in the water tank 230, the hydrogen pressure in the upper space S ₂ through the water pipe 234 and water channel l ₈ led to water pipe 235, the water pipe 235 extends up to the bottom of the transparent casing. Accordingly, even when a large amount of hydrogen water in the casing 202 is consumed, the lower end of the water pipe 235 is opened and hydrogen gas is prevented from flowing to the drinking water tank 230 side. A liquid level sensor 236 is provided in the vicinity of the upper side wall of the transparent casing 202. The liquid level sensor 236 detects when the water in the transparent casing 202 is consumed and the liquid level drops below a certain height position. Then, the valve 231 is opened to supply hydrogen to the upper space S ₂ , push the water surface in the drinking water tank 230 to feed water into the transparent casing 202, and when the liquid level sensor 236 detects the rise of the water surface, the valve 231 Is closed, hydrogen supply is stopped, and water supply from the drinking water tank 230 is stopped.

In the above-described embodiment, the drinking water tank 230 is provided. However, when water consumption is small, tap water is directly supplied into the hydrogen water tank 201 without providing the drinking water tank 230. You can also In this case, an electromagnetic valve 401 is provided in the tap water supply means (water supply means: water pipe 235), and the electromagnetic valve 401 is opened and closed by a signal from the liquid level sensor 236. Since the water purifier 400 of the faucet 206 has water resistance, a water supply pump SP is attached as necessary. Thus, when tap water is directly supplied to the hydrogen water tank 201 using the tap water pressure (about 2 atm), it is not necessary to press the water in the drinking water tank 230 with the hydrogen pressure, and the water path ₁₈ is also provided. It becomes unnecessary.

  The hydrogen tank is a hydrogen cylinder in which hydrogen of 10 atm or less is stored, and a solid hydrogen source such as sodium hydride (NaH) or sodium borohydride (NaBH) is used to pour water into the hydrogen tank. It may be generated.

  Since the hydrogen cooking system of the present invention can provide delicious hydrogen cooking and hydrogen water without discharging carbon dioxide, it can be used in the food and drink industry that provides food and drinking water on the spot.
