る。(C) Problems to be Solved by the Invention Boiled eggs are desired to have a good appearance with the yolk located in the center of the egg white when cut into slices, , In order to produce an aged egg with the yolk in the center because the yolk moves upward due to buoyancy, the egg yolk should be rotated appropriately during heating so that the position of the yolk in the egg is not biased. It is necessary to uniformly heat and solidify while making the position of (1) to be in the center.
このような方法で熟成卵を製造することは、例えば熟

た。Also, the production of boiled eggs is performed by heating and coagulating the eggs, but rapid heating of the eggs increases the rupture rate and reduces the yield of the boiled eggs, so it must be avoided, and each time the boiled eggs are produced, It must be heated again under the prescribed temperature control. Therefore, drain the heated water used once,
Fuel costs increase due to the pumping of water of a certain temperature, which increases the cost, and the handling of large-capacity containers containing heated water is always dangerous and a problem for workers. It was

卵における卵白の軟らかさが一様にならず問題である。In order to hold the egg in a standing state and irradiate it with far-infrared rays from above and below to heat it, a holder is required to hold the egg. Is not uniform, and the amount of far infrared rays received per volume differs between the body and both ends of the egg, depending on the shape of the egg, and the heating temperature also differs. Such non-uniform heating increases the egg breaking rate and is a problem. Further, since the blunt end and the sharp end are heated more strongly than the body, the softness of the egg white in the boiled egg is not uniform, which is a problem.

ように形成されるのが好ましい。In the present invention, the heated egg is held upright in the egg holding hole of the egg holding member so that such heated water can smoothly flow down the surface of the egg shell. The egg-holding hole is shaped so that the contact area between the egg-shell surface and the wall surface of the egg-holding hole is as small as possible so that the heated water can also flow down to the egg-shell surface located in the holding area. It is formed. In this case, since the flowing heated water flows through the gap formed between the surface of the eggshell and the wall of the holding hole, it is preferable that the flowing heated water is not disturbed.

に設計するのが望ましい。In the present invention, the egg holding hole formed in the egg holding member is provided with a plurality of protrusions protruding inside the hole for holding the egg. The convex portion supports the egg and at the same time forms a gap between the wall surface of the egg holding hole and the surface of the egg shell to secure a flow path for the heated water. It is desirable to design so that the flow of heated water flowing through does not stop.

生じない。In the present invention, the heated water is poured onto the eggs from the holes for supplying the heated water of the heated water distribution tank provided above the egg holding member. The heated water poured on the egg flows down through the gap formed between the egg shell and the wall surface of the hole, but can be made to flow down on the surface of the egg shell in any of the strip-like and film-like forms. When the heated water flows down in a strip shape, the egg shell portion that is not in contact with the heated water is heated by the steam generated from the poured heated water, so that the heated eggs do not have uneven heating.

As it matches the direction of gravity, the buoyancy of the yolk balances with the force generated in the lower karaza, and in the aged egg, the yolk is a samurai located in the center, heating without changing its position. To be done. Further, in the present invention, the heating water poured into the eggs is different in the flow of the heating water flowing over the egg shell depending on the flow rate, but when the heating water flows so as to wrap the eggs in a film, the eggs are Can be heated uniformly by the heated water, and when the poured heated water flows like a band, the eggs are uniformly heated by the heated water and the steam generated from the heated water.

When the temperature of the egg reaches, for example, about 50 ° C, for example, the flow path switching valve 21 (Fig. 3) is switched to the pump 32 (Fig. 3).
Is stopped to stop the supply of the low-temperature heating water to the heating water supply tank 4, and the pump 27 (FIG. 3) is operated to, for example, the heating tank 25 (FIG. 3). High-temperature heating water is supplied to the heating water supply tank 4. The temperature of this high-temperature heating water is, for example, about 90 ° C. in the case of fully-heated eggs, and about 65 ° C. in the case of soft-boiled eggs. In this case, the heating temperature of the egg is raised stepwise and the egg is rapidly heated under a relatively large temperature difference to produce a ripe or soft-boiled egg.

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 example, the eggs are heated by flowing the heated water in a thin film on the egg shell in any heating step. In this way, when the heated water is made to flow in a thin film on the egg shell, the heated water wraps around the entire surface of the egg and flows down, so that the heat transfer rate is increased and the egg can be heated uniformly. In addition, in the heating water supply tank 4 and in the sprinkling stage, the inside of the housing 2 is filled with steam that evaporates from the heating water,
The heated water flowing in a thin film is heated from outside by steam having the same temperature as the heated water, so that the eggs are heated uniformly 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大きく保って、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 maintaining a relatively large temperature difference between the egg and the heating water while extremely lowering the egg rupture rate, efficient heating is performed, so that the time for producing an aged egg can be shortened. it can.
