When the internal temperature Ti reaches −20 ° C., the control unit 16 obtains the surface temperature T obtained from the surface sensor unit 2s as the temperature characteristic shown by the phantom line curve Ms in FIG.
Based on s, feedback control is performed so that the surface temperature Ts becomes −20 ° C. That is, at point Sb in FIG.
When the internal temperature Ti reaches −20 ° C., the refrigerator 14 is stopped, the refrigerator 14 is started when the surface temperature Ts reaches −19 ° C., and the refrigerator 14 is started when the surface temperature Ts reaches −21 ° C. Control to stop.

On the other hand, the control unit 16 measures the cooling time Xq from the start of cooling until the internal temperature Ti reaches −20 ° C. with a timer or the like. In this way, if the cooling time Xq is measured, the internal temperature T will be reduced in the subsequent cooling of the same food material.
There is no need to detect i. That is, from the start of cooling, the freezing process by continuous cold air is performed for the cooling time Xq, and after the cooling time Xq has elapsed, the surface temperature Ts is monitored and the surface temperature T
Feedback control may be performed so that s becomes −20 ° C.

As described above, the method for cooling foodstuffs in the refrigerator according to the present invention detects the surface temperature and / or the internal temperature of the foodstuffs and sets the surface temperature to a temperature just before the freezing temperature of the foodstuffs. Until the set temperature is reached, rapid cooling is performed with cold air at a temperature lower than the first set temperature, and after the surface temperature reaches the first set temperature, the surface temperature is maintained at the first set temperature. Control, and until the internal temperature reaches the second set temperature set to the freezing temperature of the food,
In addition to performing rapid cooling with cold air at a temperature lower than the second set temperature, after the internal temperature reaches the second set temperature, the surface temperature is controlled to be maintained at the second set temperature. In addition to suppressing the growth of various bacteria, the freshness, taste, nutritional value and the like can be maintained, and the optimum rapid cooling in the vacuum cooking method can be performed, which is a remarkable effect.
