The above method of producing dry fruits and vegetables comprises the freezing step wherein fruits and vegetables are frozen at about 0oC to about -20oC for a definite period of time depending on the kind and properties of the fruits and vegetables, and the drying step wherein hot water is circulated through a heat pipe and the fruits and vegetables having been treated in the freezing step are dried with a hot air stream which is obtained by blowing an air stream toward the heat pipe as described above. |
