Abstract
An ice making machine comprises a housing having a cooled wall. A eutectic mixture is passed across the wall to be cooled below its freezing point and form ice. A blade continuously wipes the wall to move the fluid away from the wall and into the body of the fluid. The blades are moved by a drive means at a rate such that the surface is wiped prior to crystalization of the ice on the wall.
Claims19
An ice-making machine comprising housing to receive a fluid from which ice is to be made and having an outlet to permit the egress ice from said housing,
- a heat exchanger means located within said housing and having a coolant inlet and a coolant outlet to permit a flow of coolant to extract from said fluid, and including at least one heat exchange surface separating coolant from said fluid,
- means to maintain a body of fluid in said housing to fill substantially said housing and cover said heat exchange surface,
- blade means in contact with said surface and movable about an axis to move across said surface, and drive means operable upon said blade means to drive said blade means about said axis, said drive means moving said blade means across said surface at a speed such that successive passes of said blade means removes a cooled layer prior to crystallization of ice on said surface, said blade means being configured to discharge fluid from said surface into the body of fluid in said housing to maintain a substantially uniform temperature therein.
An ice making machine comprising a housing having an inlet and an outlet to enable fluid to circulate through said housing, a plurality of heat exchangers disposed in said housing and each having an inlet and an outlet to permit circulation of coolant therethrough, each of said heat exchangers including a pair of oppositely directed heat exchange surfaces to transfer heat from fluid within said housing to cool said coolant, means to maintain a body of fluid in said housing to fill substantially said housing to cover said heat exchange surface, a blade assembly to cooperate with said heat exchangers to inhibit deposition of ice on said heat exchange surfaces, said blade assembly including a plurality of blades in contact with respective ones of said surfaces of rotatable about an axis generally perpendicular to a plane containing said surfaces, and drive means to rotate said blade assembly at a rate such that the interval between successive passes of said blades is configured to remove a cooled layer from said surfaces prior to crystallization of ice on said surface, said blade means being configured to discharge fluid from said surface into the body of fluid in said housing to maintain a substantially uniform temperature therein.
An ice making machine comprising a housing to receive a fluid from which ice is to be made and having an outlet to permit egressive ice from said housing,
- a heat exchanger located within said housing and having a coolant in a coolant outlet to permit a flow of a coolant to extract heat from said fluid, and including at least one heat exchange surface separating coolant from said fluid,
- means to maintain a body of fluid in said housing to fill substantially said housing and cover said heat exchange surface,
- blade means in contact with said surface movable about an axis to move across said surface, said blade means including a blade inclined to said surface, and drive means operable upon said blade means to drive said means about said axis, said drive means moving said blade means across said surface at a speed such that the interval between successive passes of said blade means being configured to remove a cooled fluid from said surface into the body of fluid inset housing to maintain a substantially uniform temperature therein.
