In one method, first, a liquid food, etc. is heated to evaporate and concentrate the moisture contained therein. The concentrate is then dried for a predetermined time to remove residual moisture, and then prepared into a granular powder through a grinding process.

However, this method requires the use of several separate units of concentrators, dryers, and mills, which is expensive to purchase and maintain its operation, requires a large space and can be contaminated during the transfer of the treatment. And various problems such as causing a severe labor intensity.

Therefore, as a more advanced technology, an apparatus has been developed that can produce liquid foods and the like as concentrated powders through one device.

However, such a conventional apparatus has a disadvantage in that the completion time of drying the liquid food and the like can only be checked with the naked eye, and there is a problem that it is impossible to confirm whether the complete drying is performed when the naked eye is checked.

This is to accurately detect the completion of the powder formation in accordance with the temperature change of the heat conducted from the bath (110).

That is, when the liquid food is powdered, the temperature gradually rises from the beginning to a predetermined time as shown in FIG. 4, and when a certain time is reached, a section (A) where a constant temperature is maintained appears, in which the evaporation of the liquid food is performed. This is done vigorously.

The evaporation is actively performed and the temperature rises again (B). At this time, the state of the liquid food is maintained in a gel state, and then a constant temperature is maintained, thereby completely transforming the solid into a highly concentrated powder.

In this way, the powder formation is completed by the notification sensor 130 generates a warning sound when the temperature is kept constant (finally) or after a predetermined period has elapsed from this time. It can help you know if

For example, when the temperature required for powdering the liquid food is 80 ° C., when the water in the bath is heated to 80 ° C., the water in the bath is used for phase change of the liquid food while rising, horizontal, When the liquid food is completely converted into powder form, the water in the bath reaches 80 ° C and remains constant, and the temperature conducted to the heating vessel reaches and stays at 80 ° C so that the alarm sensor detects and alerts it. Let sound be generated.
