The heat plate 102 is supported by a cooling fan 103 provided in the case 101, and is surrounded by a heat-resistant cover 101a that is an inner wall of the case. An air passage 110 is formed between the heat plate 102 and the heat-resistant cover 101a.
- the cooling fan 103 is rotated, and the milk preparation pot 120 is cooled by the air flowing from the air intake port 104.
- a concentrate is prepared by mixing a necessary amount of formula with a certain amount of hot water. And it is comprised so that the milk of a suitable temperature may be adjusted by adding the liquid of low temperature so that the final volume of a mixture may be reached with respect to the concentrate.
- liquid cooling mechanism in the conventional beverage production apparatus has the following problems.
- the milk preparation pot heating device 100 disclosed in Patent Document 1 cools the outer wall of the milk preparation pot 120 through the air passage 110 by the air flowing in from the air intake 104 by the rotation of the cooling fan 103 in the case 101.

- the sub-airflow AF2 is generated in the milk preparation pot 4 by diverting to the same.
- the milk M is cooled by applying the indirectly divided substream AF2 to the liquid level of the milk M.
- the sub airflow AF2 in the milk preparation pot 4 is not a part of the liquid surface but the entire liquid surface because the flow velocity of the horizontal airflow component flowing along the liquid surface of the milk M is relatively fast.

For this reason, the risk that foreign matter such as dust is mixed with the outside air from the gap d into the milk preparation pot 4 is reduced. Further, when the gap d between the open portion 4 b and the opposed lower surface 34 a of the air flow path 34 is 5 mm or more, the air current leaks from the gap d, and the liquid level of the milk M in the milk preparation pot 4 The sub-airflow AF2 that is a swirling flow along the line is less likely to be generated.

- Milk M containing bubbles increases the air that enters the baby's stomach when breastfeeding. As a result, a large belch is likely to come out from the baby, and in a baby whose belp is still not good, the milk M can be easily spit out at the beat.
- Such spitting back of milk M requires refeeding or frequent feeding of the baby, and greatly increases the burden on the breastfeeding person such as the mother. Therefore, the method for producing milk M containing a large amount of bubbles is very inappropriate as a method for producing milk M to be given to a baby. Therefore, a liquid cooling method that can reduce the inclusion of bubbles in the milk M is desired.

Abstract
Description
(2)石鹸と清浄な水とで手指を洗い、清潔な布又は使い捨てのナプキンを用いて水分を拭き取る。
(3)十分な量の安全な水を沸騰させる。
(4)火傷に気をつけて、70℃以上にまで冷却した適量の沸騰させた水を、清潔で滅菌済みのコップ又は哺乳ビンに注ぐ。
(5)表示された量の乾燥粉末乳を正確に量って加える。
(6)水道の流水の下に置くか、冷水又は氷水の入った容器に静置することにより、授乳に適した温度まで短時間で冷却する。
(7)哺乳用コップ又は哺乳ビンの外側を清潔な布又は使い捨ての布で拭き、乾燥粉末乳の種類、乳児の名前若しくは識別番号、調乳した日付と時刻、又は調乳した職員の名前等の必要な情報を表示する。
(8)非常に高温の湯が調乳に使用されるため、乳児の口に火傷を負わさないよう、授乳する前に授乳温度を確認することが不可欠である。
(9)調乳後2時間以内に消費されなかった乾燥粉末乳は、全て廃棄すること。
以下、本発明の実施形態について、詳細に説明する。本発明の一実施形態について、図1~4に基づいて説明すれば、以下の通りである。
まず、図1に基づいて、粉末乳調乳装置(飲料生成装置)1Aの構成について説明する。
(2)供給配管10における、ヒーター12に覆われた、U字状の部分へ流入された液体Lは、フロート式逆止弁11が取り付けられている高さまで満たされる。
(3)ヒーター12による加熱が開始されると、液体Lは沸騰し、その蒸気圧でヒーター12から押し上げられる。
(4)ヒーター12の入口側にはフロート式逆止弁11があるため、逆側のヒーター12出口からのみ液体Lが押し出され、該液体Lは供給配管10を経由して給湯口13に供給される。
(5)供給配管10におけるヒーター12に覆われた部分内の液体Lが減少することによって、供給配管10におけるヒーター12に覆われた部分内部の圧力が低下し、フロート式逆止弁11が開く。この結果、(1)に戻って加熱前の液体Lが流入する。
尚、本実施形態のヒーター12には、図示しない温度センサーが設置されており、ヒーター12の加熱温度を常に測定できるようになっている。
ここで、本実施形態の粉末乳調乳装置1Aに備えられた液体冷却装置10Aの構成について、説明する。
