止している。The operation of this clean steam generator will be described in detail below. First, live steam V 1 from the boiler is supplied from an introducing pipe 7 provided in the condensing part 2 of the straight body 5, and is blown into the liquid 1 in the condensing part 2 from a blowing part 8 at the tip of the introducing pipe 7. . The live steam V 1 blown in this way is
While a large number of bubbles are dispersed and risen, they come into contact with the liquid 1 to deprive the amount of heat and once condensed. The condensed vapor is re-evaporated from the gas-liquid interface 3 by obtaining the amount of heat of the freshly-injected raw steam V 1 . The re-evaporated vapor V 2 rises in the gas-liquid separating section 4 of the straight body 5 and flows out from the outlet 13. At this time, the heat insulating material 18 attached to the outer periphery of the straight body 5
As a result, the vapor V 2 rising in the gas-liquid separation section 4 is kept warm,
It prevents the increase of wetness due to the temperature drop due to heat radiation.

Are separated and become clean steam V 3 and taken out from the outlet pipe 17. On the other hand, the entrained droplets separated from the vapor V 2 become droplets or liquid film, flow down in the discharge pipe 16 and are returned to the liquid 1 in the condensing part 2.

る。By the way, since the clean steam V 3 is generated by passing through the liquid 1 (for example, boiler water) in the condensing part 2, the dryness is about 1.0.
It is zero saturated steam. Therefore, the saturated vapor V 2 re-evaporated from the gas-liquid interface 3 of the condenser 2 rises in the gas-liquid separator 4 and reaches the outlet 13, so that the degree of wetness tends to increase due to the temperature decrease due to heat radiation. Such moist steam having an increased degree of moistness is generally unsuitable for use in the food industry and the like. For example, when using clean steam of saturated steam in the rice steaming process of the sake industry, if the saturated steam takes a long distance to reach the rice grain, it will become damp steam due to temperature decrease and excess moisture in the steam will cause the rice grain to It may be difficult to perform uniform and good steaming due to partial swelling.

The heat insulating material 18 is used to prevent the saturated vapor V 2 rising in the gas-liquid separation section 4 from lowering its temperature due to heat radiation.

A method of attaching a heating device such as a heater to the outer periphery of the straight body 5 and positively heating the saturated vapor V 2 that is re-evaporated and rises by this heating device may be considered. Since the device must be attached, the entire device becomes large and the cost of the product is increased, which is not suitable.

It is to provide a clean steam generator capable of suppressing an increase in frequency.

る。The operation of the clean steam generator of the present invention will be described in detail below. First, live steam V 1 from the boiler is supplied from the inlet 29 of the straight body 25. This inlet 29
The live steam V 1 from the boiler supplied from
Flowed down from the gas-liquid separating section 24 of the straight body 25 into the liquid 21 of the condensing section 22, and the lower end of the inner cylinder 28 opened in the liquid 21 of the condensing section 22. The liquid is blown into the liquid 21 from the blowing port 30 of the introduction path 27.

を上昇して導出口３５から流出する。In the condensing section 22, the live steam V 1 blown into the liquid 21 becomes a large number of bubbles and contacts the liquid 21 while being dispersed and rising. The condensed vapor obtains the amount of heat of the freshly injected raw steam V 1 and re-evaporates from the gas-liquid interface 23.
The vapor V 2 re-evaporated is used in the gas-liquid separation section 24 of the straight body 25.
And flows out from the outlet 35.

湿り度が増加することを確実に抑止できる。At this time, since the introduction path 27 of the live steam V 1 is formed between the gas-liquid separation section 24 of the straight body 25 and the condensation section 22 and the inner cylinder 28, the introduction path 27 is formed. The gas-liquid separation part 24 of the straight body 25 is fed by the flowing raw steam V 1.
The vaporizing vapor V 2 of the re-evaporation which rises is heated. That is, since the live steam V 1 supplied from the boiler is at a higher temperature than the re-evaporated steam V 2 rising in the gas-liquid separation section 24 of the straight body 25, the re-evaporated steam V 2 is The raw steam V 1 flowing down the introduction path 27 of the cylinder 28 is heated to a temperature higher than the heat retention. By the heating with the live steam V 1 , it is possible to reliably prevent the steam V 2 rising in the gas-liquid separation section 24 from increasing in wetness due to the temperature decrease due to heat radiation.

It becomes 3 and is taken out from the outlet pipe 39. On the other hand, steam V
The entrained droplets separated from 2 become droplets or liquid film, flow down in the discharge pipe 38, and are returned to the liquid 21 in the condensing part 22.
