THE PRESENT INVENTION RELATES TO A METHOD FOR PREPARING DRIED ALPHA-RICE BY VACUUM DRYING COMPRISING: (A) WASHING OUT IMPURITIES FROM THE SURFACE OF HULLED-RICE BY USING A WASHING DEVICE; (B) IMMERSING THE WASHED RICE IN WATER FOR 3 TO 120 MINUTES TO CONTAIN WATER UNIFORMLY, AND THEN DRYING IT NATURALLY FOR 3 TO 30 MINUTES; (C) PUTTING THE SOAKED RICE INTO AN AUTO CONVEYOR RICE COOKER, WHEREIN THE TEMPERATURE OF WATER IS MAINTAINED AT 80 TO 98°C, AND THEN SCALDING IT FOR 8 TO 20 MINUTES TO BE BOILED RICE; (D) COOLING THE BOILED RICE RAPIDLY BY SHOWER AT FIRST, AND THEN WASHING OUT IT IN A COOLING TANK SECONDLY; AND (E) PUTTING THE BOILED RICE INTO A VACUUM DRYING ROOM, WHICH TEMPERATURE IS MAINTAINED AT 60 TO 98°C, AND REDUCING THE INTERNAL PRESSURE TO BELOW 1 MMHG, AND THEN VACUUM DRYING THE BOILED RICE UNTIL ITS WATER CONTENT BECOMES LESS THAN 5%. |
