Method of operating auger ice-making machine
A method of operating an auger ice-making machine having a refrigeration casing, an auger screw rotatably disposed inside the casing and feeding, while scraping, the ice frozen on an inner wall surface of the casing, a stocker for storing/retaining the ice fed, the stocker being formed with an ice discharge port of the stocker in order to discharge the ice to an exterior of the machine by being opened, and a stored-ice detector for detecting a high level, and a low level, of a quantity of ice stored within the stocker, wherein: when the stored-ice detector detects the high level, a controller is activated to stop ice-making operation, and when the quantity of ice stored decreases below the low level by a required quantity, the controller restarts the ice-making operation; and when the controller judges, during a stopped state of the ice-making operation, that a block of ice has occurred in the stocker, the controller restarts the ice-making operation, provided that the stored-ice detector has detected the low level.
1. A method of operating an auger ice-making machine having:
a refrigeration casing for freezing ice on an inner wall surface of the casing;
an auger screw, rotatably disposed inside the casing, for feeding, while scraping, the ice frozen on the casing inner wall surface;
a stocker for storing/retaining the ice fed by the auger screw; and
stored-ice detection means for detecting a high level, and a low level, of a quantity of ice stored within the stocker; wherein
ice is discharged to an exterior of said ice-making machine when an ice discharge port formed in the stocker is opened; and
said method comprising the ordered steps of:
allowing the control means to judge that a block of ice has occurred in the stocker when a total ice discharge time of the ice discharged from the ice discharge port reaches or exceeds a previously set required time required for discharging a greater quantity of ice than a reference ice storage quantity of the ice stored during a time from detection of the low level to that of the high level, provided that the high level is detected by the stored-ice detection means, and then
allowing the ice-making operation to be restated when the control means judges, during a stopped state of the ice-making operation, that a block of ice has occurred in the stocker, provided that the stored-ice detection means has detected the low level.
2. A method of operating an auger ice-making machine having:
a refrigeration casing for freezing ice on an inner wall surface of the casing;
an auger screw, rotatably disposed inside the casing, for feeding, while scraping, the ice frozen on the casing inner wall surface;
a stocker for storing/retaining the ice fed by the auger screw; and
stored-ice detection means for detecting a high level, and a low level, of a quantity of ice stored within the stocker, wherein
ice is discharged to an exterior of said ice-making machine when an ice discharge port formed in the stocker is opened, and
said method comprising the ordered steps of:
allowing control means for monitoring a quantity of discharge from the ice discharge port and a quantity of molten ice within the stocker to be activated to stop ice-making operation when the stored-ice detection means detects the high level; and
the allowing the control means to restart the ice-making operation, provided that an actual ice decrement that is a sum of, a total quantity of ice discharge from the ice discharge port and a total quantity of molten ice within the stocker, has exceeded a previously set initial operating quantity of ice.
