For example, a preheating tank 23 (Fig. 3), preferably at 20 to 30°C.
Heated water at a relatively low temperature is supplied from the heated water supply pipe 7 into the heated water supply tank 4. This low-temperature heated water is supplied from the heated water flow hole 5 of the heated water supply tank 4 to the support hole 1 of the non-supporting shelf board 12.
Pour into the blunt end of the egg 14 located at 3. 14 eggs
The cold heated water poured into the blunt end of the eggshell flows in a thin film around the eggshell and heats the egg. Once the eggs have been heated to or near the temperature of the low-temperature heated water, the heating device 29
(Fig. 3) is operated to gradually raise the temperature of the water poured into the eggs, and the heating temperature of the eggs is gradually raised to produce fully ripe or soft-boiled eggs.
本例装置においては、前記卵を連続的な加熱温度上昇の
下に加熱熟成させる以外に、卵を加熱する加熱水の温度
を不連続に上昇させて卵を加熱熟成させることができる
。In the apparatus of this example, in addition to heating and ripening the eggs while continuously increasing the heating temperature, it is also possible to heat and ripen the eggs by discontinuously increasing the temperature of the heated water that heats the eggs.
この場合、連続的に加熱温度を上げて卵を加熱する場合

１２の支持穴１３に配置されている卵１４の鈍端部に注
ぎ、卵殻の周囲を薄膜状に流して卵を加熱する。In this case, as in the case of heating eggs by continuously increasing the heating temperature, the temperature of the eggs is low at first, for example, 20
Low-temperature heated water of ~50°C, preferably 20~30°C, from the preheating tank is supplied from the heated water supply pipe 7 into the heated water supply tank 4, and from the heated water flow lower hole 5 of the heated water supply tank 4, the heated water is It is poured onto the blunt end of the egg 14 placed in the support hole 13 of the support shelf 12, and the egg is heated by flowing a thin film around the eggshell.
この卵への低温の加熱水の散水を所定時間続けたところ
で、加熱装置２９を作動させて、卵に散水する低温の加
熱水の温度を徐々に上昇させて、卵を徐々に加熱する。After this sprinkling of low-temperature heated water onto the eggs continues for a predetermined period of time, the heating device 29 is activated to gradually raise the temperature of the low-temperature heated water sprinkled onto the eggs, thereby gradually heating the eggs.

熱水の温度は、例えば完熟卵の場合で、約９０℃の温度
であり、半熟卵の場合は、約６５°Ｃである。この場合
、卵の加熱温度は段階的に上げられ、卵は比較的大きい
温度差の下に急速に加熱され、完熟卵又は半熟卵が製造
される。When the temperature of the egg reaches, for example, about 50°C, for example, the flow path switching valve 21 (Fig. 3) is switched, the operation of the pump 32 (Fig. 3) is stopped, and the heated water at low temperature is supplied. At the same time as stopping the supply to the tank 4, the pump 27 (FIG. 3) is operated to supply, for example, relatively high temperature heated water from the heating tank 25 (FIG. 3) to the heated water supply tank 4. The temperature of this high-temperature heated water is, for example, about 90°C for fully ripened eggs, and about 65°C for half-boiled eggs. In this case, the heating temperature of the eggs is raised stepwise, and the eggs are rapidly heated under relatively large temperature differences to produce fully ripe or soft-boiled eggs.
本例においては、何れの加熱態様の加熱段階においても
、加熱水を卵殻上に薄膜状に流して、卵は加熱される。In this example, in the heating stage of either heating mode, the egg is heated by flowing heated water in a thin film over the eggshell.
このように、加熱水を卵殻上に薄膜状に流すと、加熱水
は卵の全表面を包み込んで流下するために、熱伝達率は
大きくなり、しかも、卵を均一に加熱することができる

蒸発する蒸気によってハウジング２内は充たされ、薄膜
状に流下する加熱水は、外側から加熱水と同温度の水蒸
気によって加熱されるので、卵は一定の温度で均一に加
熱されることとなる。In this way, when the heated water is poured over the eggshell in a thin film, the heated water wraps around the entire surface of the egg and flows down, increasing the heat transfer coefficient and heating the egg evenly. In addition, the inside of the housing 2 is filled with steam evaporated from the heated water in the heated water supply tank 4 and during the water sprinkling stage, and the heated water flowing down in a thin film is heated from the outside by steam having the same temperature as the heated water. Therefore, the eggs will be heated evenly at a constant temperature.
したがって、本例においては、破卵率を極度に低くしな
がら、卵と加熱水の温度差を比較的太きく保って、効率
の良い加熱を行うので、熟成卵を製造する時間を短くす
ることができる。Therefore, in this example, while keeping the egg breaking rate extremely low, the temperature difference between the eggs and the heated water is kept relatively large to perform efficient heating, which shortens the time it takes to produce aged eggs. I can do it.
