Abstract
A dough conditioning apparatus for frozen dough including: an enclosure; at least one tray or conveyance for supporting at least one frozen dough piece within the enclosure; a means to direct a conditioning gas directly onto frozen dough within the enclosure; humidity and temperature sensors for respectively measuring the humidity and temperature of the conditioning gas; and a gas controller, the gas controller controlling the duration of the conditioning gas onto the frozen dough according to the output of the humidity and temperature sensor.
Claims12
A dough thawing apparatus for thawing one or more initially frozen dough pieces prior to baking the dough pieces, the apparatus including:
- (a) an enclosure;
- (b) a heat and humidity supply system for heating and humidifying air within the enclosure;
- (c) a plurality of trays or conveyances for supporting the one or more initially frozen dough pieces within the enclosure;
- and
- (d) a dough conditioning gas supply system for drying the exposed surfaces of the one or more initially frozen dough pieces supported by the plurality of trays or conveyances comprising:
- (i) a gas collector communicating with the outside of the enclosure, the gas collector including a fan for drawing outside air into the enclosure;
- (ii) a heater for conditioning the air drawn into the enclosure;
- (iii) gas conduits for supplying the conditioned air from outside the enclosure only to ducts overlying each of the trays or conveyances within the enclosure, each overlying duct having one or more outlets, each of the one or more outlets being configured to direct a respective stream of the conditioned air directly onto the one or more initially frozen dough pieces supported by the trays or conveyances at a velocity sufficient to dry the exposed surfaces of the one or more initially frozen dough pieces;
- (iv) humidity and temperature sensors for respectively measuring the humidity and temperature of the conditioned air;
- and
- (v) a gas controller for controlling the duration during which the conditioned air is directed onto the one or more initially frozen dough pieces according to the humidity and temperature of the conditioned air measured by the humidity and temperature sensors.
A dough thawing apparatus for thawing one or more initially frozen dough pieces prior to baking the dough pieces, the apparatus including:
- (a) an enclosure;
- (b) a heat and humidity supply system for heating and humidifying air within the enclosure;
- (c) a plurality of trays or conveyances each for supporting the one or more initially frozen dough pieces supported on the trays or conveyances within the enclosure;
- (d) a cooler for reducing the temperature within the enclosure below that of the external environment;
- and
- (e) a dough conditioning gas supply system for drying the exposed surfaces of the one or more initially frozen dough pieces supported by the plurality of trays or conveyances comprising:
- (i) a gas collector communicating with the outside of the enclosure, the gas collector including a fan for drawing outside air into the enclosure;
- (ii) a heater for heating the air drawn into the enclosure to create conditioned air;
- (iii) gas conduits for supplying the conditioned air only to ducts overlying each of the trays or conveyances within the enclosure, one or more outlets located in each overlying duct, each of the one or more outlets in each duct being configured to direct a respective stream of the conditioned air directly onto the one or more initially frozen dough pieces supported by the respective trays or conveyances at a velocity sufficient to dry the exposed surfaces of the one or more initially frozen dough pieces;
- and
- (iv) a controller for controlling the cooler to cool and maintain the one or more initially frozen dough pieces in a frozen state within the enclosure for a predetermined time, then controls the heater to heat the air directed onto the one or more initially frozen dough pieces to heat the one or more initially frozen dough pieces.
