<p>PURPOSE: To provide a method for producing ANPO-GAKI of a dried astringent persimmon having the residual moisture content regulated to about 30-50% by which the ANPO-GAKI can be produced in a short period anywhere at any time without any regional and seasonal restriction, and also provide an apparatus for producing the ANPO-GAKI. CONSTITUTION: A peeled persimmon is immersed in a mixed solution of an aqueous solution of ascorbic acid with an aqueous solution of a saccharide within 30min and the residual aqueous solution components are then removed therefrom. The persimmon is exposed to dry air while being irradiated with far infrared rays to remove the moisture content of the persimmon to about 30-50% and the slow freezing treatment of the resultant persimmon is subsequently carried out at -15 to -20 deg.C for >=12hr. Thereby, ANPO-GAKI is produced. Furthermore, the apparatus for producing the ANPO-GAKI is obtained by supporting flat type reticulated containers 2, containing each persimmon (a) for processing and arranged therein side by side in many stages in a drying rack 3, irradiating the persimmon with far infrared rays with far infrared ray heaters 43 from the sides thereof, traveling and moving the far infrared ray heater 43 on circuits along the sides of the drying rack 3 with driving motors 5 and arranging reflecting plates 6 for reflecting the far infrared rays irradiated from the sides downward in the upper part of the respective stages in the drying rack 3. In addition, a dehumidifier 7 is capable of dehumidifying and drying air in the chamber and a fan 8 is capable of circulating the air in the chamber at 0.6-0.8m wind velocity.</p> |
