Description

蒸煮後の穀物を真空チャンバ内に収容し、真空ポンプによって前記真空チャンバ内を減圧して蒸煮穀物内に含まれる水分を蒸発させて醸造や発酵に適した含水量にするとともに、その気化熱によって蒸煮穀物の温度を急速に低下させる蒸煮穀物の冷却方法、及びそれに使用する蒸煮穀物冷却装置に係り、蒸煮穀物から蒸発した水蒸気を冷却して復水する凝縮器内に、底部に冷媒を循環させるパイプを備えたトレー配設し、該トレーに注入した水を冷媒の循環によって凍結して氷盤とし、該氷盤上に真空ポンプで吸引した水蒸気を含む空気を導いて冷却し水蒸気を氷盤上に復水し、乾燥した空気のみを真空ポンプから外部に排出する蒸煮穀物の冷却方法、及び蒸煮穀物冷却装置に関する。   The steamed grain is stored in a vacuum chamber, and the vacuum chamber is depressurized by a vacuum pump to evaporate the moisture contained in the steamed grain to a moisture content suitable for brewing and fermentation, and by the heat of vaporization. The present invention relates to a method for cooling a steamed cereal that rapidly lowers the temperature of the steamed cereal, and a steaming cereal cooling device used for the method, and circulates a refrigerant at the bottom in a condenser that cools and condenses water vapor evaporated from the steamed cereal. A tray provided with a pipe is arranged, and water injected into the tray is frozen by circulation of a refrigerant to form an ice plate, and air containing water vapor sucked by a vacuum pump is guided onto the ice plate and cooled to cool the water vapor. The present invention relates to a method for cooling a steamed cereal, in which only the dried air is discharged from a vacuum pump, and the steamed cereal cooling device.

清酒醸造用の蒸米をはじめ、味噌、醤油等発酵食品用の大豆等蒸煮穀物の冷却とこれらに含まれる水分の蒸散には、従来から、ベルトコンベア上に堆積させた蒸米や蒸煮穀物に大気又は冷風を吹き付ける装置が広く用いられてきている。
しかし、大気や冷気を吹き付けての冷却ではベルトコンベアに堆積した蒸米や蒸煮穀物を均等に冷却することは難しく、表面と内部に大きな温度差ができ、またコンベア上を通過し終えた蒸米や蒸煮穀物の含水量も表面は少なく内部が多く均一性に欠けるという問題があり、また、大気中や冷気中に含まれる雑菌によって蒸米や蒸煮穀物が汚染される恐れもあった。さらに加えてベルトコンベアを設置する広い場所も必要としていた。
この問題を解決する方策として、特に蒸米を真空容器内に収容し、真空容器内を高い真空度に保つことによって蒸米の水分を蒸発させるとともにその蒸発潜熱により蒸米を冷却させる装置の発明が、これまでに2件見られるが、未だ実用に供されるには至っていない。
特許文献1の発明では、その請求項2に
『洗米浸積された浸積米を収容し開放または軽く蓋を閉じて前記浸積米を蒸煮し蒸煮終了後前記蓋を密閉する真空容器と、前記真空容器内を高度真空度に保持し蒸米の水分を蒸発させてその蒸発潜熱により冷却させる真空ポンプと、その冷却温度を任意の5度Cないし35度Cに選定して前記真空ポンプを停止させる温度センサとを備えることを特徴とする蒸煮装置付き真空蒸米冷却装置。』が開示され、
そして、明細書の段落0016には
『本実施例では蒸煮装置付き真空蒸米冷却装置の容量として、直径30cm、内容積30リッターを備え、これに試料としタイ米70%を有し、重量310グラム、水分36.7%の蒸米を投入した真空乾燥テストを表に示す。』と記し、
段落0018に示された表1には当初67℃あった蒸米品温が2分後に30℃に、25分後に5℃まで低下し、蒸米36.7%あった蒸米の水分洋も10〜11分後には33.1%に、41〜42分後には31.8%まで低下したとの結果が示され、続けて、
『このように、蒸煮装置付き真空蒸米冷却装置により、真空缶本体1内で浸積米を蒸煮した蒸米の高真空度を確保して蒸米中の水分を飛ばし、その際の蒸発潜熱により、処理される蒸米全体の温度が任意の所要温度5度C〜35度Cに冷却され、蒸米の表面と中心部との温度差がなく、温度が均一化され、蒸米中の水分が一定となり水分率が均一化されて、雑菌による汚染の恐れがなく、長期保存が可能な清酒の醸造に最適な蒸米を確保することが可能で、取り出された蒸米は直ちに麹と混合されて清酒の仕込み工程に移ることが可能である。』とその効果が記述されている。
しかしこの効果は310グラムという極めて小容量の蒸米でのテスト結果であり、この結果を基にして実際の清酒醸造現場において扱う400kg〜1000kgの蒸米の冷却を30分程度の短時間で行おうとすれば真空容器、真空ポンプとも大型で高価となり、真空ポンプの運転コストも高いものとなる。また、装置構成が真空容器、真空ポンプと、真空ポンプを設定した冷却温度で停止させる温度センサからなるとされているので、真空容器から吸引された水蒸気は真空ポンプを経て排出されることとなり、水封ポンプにせざるを得ず、水封ポンプより小型な油回転式ポンプが使用できないという問題もある。
In order to cool steamed rice for fermented foods such as miso and soy sauce, as well as steamed rice for sake brewing, and transpiration of moisture contained in these, conventionally, steamed rice and steamed grains deposited on a belt conveyor have been exposed to the atmosphere or Devices for blowing cold air have been widely used.
However, it is difficult to cool the steamed rice and steamed grains deposited on the belt conveyor evenly by cooling with air or cold air, and there is a large temperature difference between the surface and the interior, and steamed rice and steamed steam that has finished passing on the conveyor. There is also a problem that the moisture content of the grain is small and the inside is large and lacks uniformity, and there is also a possibility that the steamed rice and steamed grain will be contaminated by various bacteria contained in the air and cold air. In addition, a large space for installing a belt conveyor was also required.
As a measure to solve this problem, in particular, an invention of an apparatus for storing steamed rice in a vacuum vessel and evaporating the moisture of the steamed rice by keeping the inside of the vacuum vessel at a high degree of vacuum and cooling the steamed rice by its latent heat of evaporation is Two cases have been seen so far, but they have not yet been put to practical use.
In the invention of Patent Document 1, the vacuum container which contains the soaked rice soaked in the washed rice and opens or lightly closes the lid, steams the soaked rice and seals the lid after cooking is completed. A vacuum pump that keeps the inside of the vacuum vessel at a high degree of vacuum, evaporates the moisture of the steamed rice and cools it by the latent heat of evaporation, and selects the cooling temperature at an arbitrary 5 degrees C to 35 degrees C and stops the vacuum pump A vacuum steamed rice cooling device with a steaming device, characterized by comprising a temperature sensor. Is disclosed,
And in paragraph 0016 of the specification, “In this embodiment, the capacity of the vacuum steamed rice cooling device with the steaming device is provided with a diameter of 30 cm, an internal volume of 30 liters, a sample having 70% Thai rice, and a weight of 310 grams. The table below shows the vacuum drying test using steamed rice with a moisture content of 36.7%. ”
In Table 1 shown in Paragraph 0018, the temperature of the steamed rice product, which was initially 67 ° C., decreased to 30 ° C. after 2 minutes and to 5 ° C. after 25 minutes. The results showed that after 3 minutes it was reduced to 33.1%, and after 41 to 42 minutes it was reduced to 31.8%.
“In this way, the steamed rice cooling device with steaming device secures the high vacuum of steamed rice that has been steamed from the soaked rice in the vacuum can body 1 and the moisture in the steamed rice is blown away. The temperature of the whole steamed rice is cooled to an arbitrary required temperature of 5 ° C to 35 ° C, there is no temperature difference between the surface and the center of the steamed rice, the temperature is made uniform, the moisture content in the steamed rice becomes constant and the moisture content It is possible to ensure the optimal steamed rice for sake brewing that can be stored for a long period of time without the risk of contamination by various bacteria, and the extracted steamed rice is immediately mixed with koji for the sake preparation process. It is possible to move. And the effect.
However, this effect is a test result with steamed rice with a very small capacity of 310 grams, and based on this result, 400kg to 1000kg steamed rice handled at the actual sake brewing site is cooled in about 30 minutes. For example, both the vacuum container and the vacuum pump are large and expensive, and the operating cost of the vacuum pump is high. In addition, since the device configuration consists of a vacuum vessel, a vacuum pump, and a temperature sensor that stops the vacuum pump at a set cooling temperature, water vapor drawn from the vacuum vessel is discharged through the vacuum pump, There is also a problem that an oil rotary pump that is smaller than a water ring pump cannot be used.

また、特許文献2の発明では、その請求項4に、
『蒸煮米を収容し密閉する真空容器と、その真空容器内を高真空度に保持し蒸米の水分を蒸発させてその蒸発潜熱により冷却させる真空ポンプと、その蒸発させた水蒸気を冷却管群に接触させて復水に戻し真空容器内を高真空度に保持する凝縮器と、凝縮器内の冷却管群に冷却水を送り込み還流した温水を再び冷水にする冷却水循環装置と、蒸米から蒸発させた水分の減量を常時計測し蒸米の含水率が目標値に到達したことを定量的に確認できる電子はかりと、減圧中の真空容器に大気圧の空気を導入する際に雑菌を除去する空気導入装置を備えることを特徴とする真空蒸米冷却調湿装置。』が開示されている。
そして段落0019に
『図2は真空蒸米冷却調湿テストの結果を示している。
本実施例では、真空蒸米冷却調湿装置として、直径600mm、高さ250mm、内容積約70リッターの容量の真空容器を使用し、これに試料として精米率50%、質量20キログラムの酒米(山田錦)を初期含水率37.5%、初期温度約45度Cで投入した場合である。』とし、段落0022と0023に
『このように、真空蒸米冷却調湿装置により、真空容器内で蒸米中の水分を飛ばし、その際の蒸発潜熱により、90分後には蒸米は10度Cに冷却され、蒸米の表面と中心部との温度差がなく温度が均一化され、また90分後には蒸米中の含水率は32.5質量%になり、その分布が均一化されて、蒸米のガラス化や雑菌による汚染の恐れがなく、取り出された蒸米は直ちに製麹工程および清酒の仕込み工程に移ることが可能である。
特に製麹工程で最も望ましいとされる蒸米の含水率を32〜33質量%に仕上げる時間は、従来手法では半日程度と言われているが、この真空蒸米冷却調湿方法の所要時間は1時間30分と非常に短時間であり、非常に迅速な蒸米調湿方法であることが実証された。』とその効果を示している。
この発明においては、蒸発させた水蒸気を冷却管群に接触させて復水する凝縮器と、凝縮器内の冷却管群に冷却水を送り込み還流した温水を再び冷水にする冷却水循環装置とを備えることによって。特許文献1の発明に比べて、水封ポンプより小型な油回転式ポンプの使用が可能になり、真空ポンプの小型化は図られはするが、前記凝縮器によって腹水した水は装置運転中は装置内に蓄えておかねばならず、そのため前記凝縮器には凝縮水溜め部が設けられている。
前記した段落0019の記述『資料として精米率50%、質量20キログラムの酒米(山田錦)を初期含水率37.5%、初期温度約45度Cで投入した場合』と、段落0022の記述『90分後には蒸米中の含水率は32.5質量%になり』との記述から、含水率は5質量%の減少、重量にして水1kgが前記凝縮水溜め部に蓄えられたこととなる。
また、前記真空ポンプの運転に先駆けて前記凝縮器に冷却水を循環させ、運転中は停止できないため、冷却水を備蓄する冷水槽を備えておくことが好ましいが、実際の清酒醸造現場において400kg〜1000kgの蒸米を冷却するには多量の冷却水が必要となり、冷水槽も大型になることが予想される。

Become.
Prior to the operation of the vacuum pump, cooling water is circulated through the condenser and cannot be stopped during operation. Therefore, it is preferable to provide a cold water tank for storing cooling water. A large amount of cooling water is required to cool ~ 1000 kg of steamed rice, and the size of the cold water tank is expected to be large.
