In the present invention, the primary steam passing through the spiral pipe 6 preferably has a gauge pressure of 2 kg/cm ² or more, and the steam is released into the space above the tank 5, the water temperature is raised to about 100°C by the primary steam, and the steam released from this is This is a method of producing humidified steam by mixing primary and secondary steam as secondary steam (saturated and humidified steam). The equipment directly used in the method is as follows. That is, a spiral pipe 6 for primary steam is provided from one side of the steaming table tank 7 filled with about half of the water to the lower part of the water layer, and the other end is bent into an inverted U shape in the upper space of the tank to form a discharge port. A steam outlet 2 for mixing primary steam and steam (secondary steam) generated by heating water in the tank is provided at the top of the tank, and a water outlet 3 is provided at the opposite side of the tank at approximately the same height as the primary steam inlet. The contents include a humidifying steam generating device with a water supply and a discharge port 4 provided at the bottom.

気が得られる。 The material of the tank is preferably metal, particularly stainless steel. The primary steam to be supplied is preferably about 2 to 5 kg/cm ² G, especially about 2 kg/cm ² G, and the heat transfer area is increased by making the steam throughflow pipe in water, which is about half filled in the tank, in a spiral shape. , the temperature of the water can be raised quickly and the temperature of the primary steam can be lowered at the same time. Therefore, generation of secondary steam from heated water is also promoted. Since this secondary steam contains a large amount of moisture, the desired humidified steam can be obtained by mixing the primary steam and the secondary steam.

Steam was released into the interior space. A steady state is reached in about 10 seconds after steam is introduced, and the low-pressure, low-temperature dry steam is released into the upper half of the tank. On the other hand, this steam heating heats the water to 100℃,
Saturated or humidified steam (secondary steam) was generated. This secondary steam and primary steam are mixed in the tank space, and this mixed humidified steam is blown out from the upper steam outlet of the tank, and when used in the production of Chinese dumplings, it is a product of excellent quality that does not harden the skin. was gotten.
