Abstract
A food thermalizer includes a food chamber which is vented to atmosphere. A wet bulb temperature sensor preferably is located adjacent to the vent and uses the condensate in the vent to keep its outer surface wet. By sensing the wet bulb temperature within the food chamber and controlling a wet heat source that heats the water in an evaporator in the food chamber, the vapor surrounding the food can serve as a vapor thermostat to control the final food temperature. The cook also can control the dry bulb temperature relative to the wet bulb temperature by controlling a dry heat source that heats the air, thereby controlling the degree of browning or texturing of the food.
Claims8
A thermalizer for cooking food, comprising:
- a food chamber;
- an evaporator in communication with said food chamber, including a first heat source which heats the water in the evaporator;
- a second heat source which heats the air inside the food chamber;
- a vent providing a path from inside of said food chamber to outside of said food chamber, for venting vapor;
- a wet bulb temperature sensor in said food chamber, wherein said wet bulb sensor is kept wet by condensate from said vent;
- a dry bulb temperature sensor in said food chamber;
- and
- a controller which controls said first and second heat sources based on signals received from said wet bulb temperature sensor and said dry bulb temperature sensor.
A thermalizer for cooking food, comprising:
- a food chamber;
- an evaporator in communication with said food chamber, including a first heat source which heats the water in the evaporator;
- a second heat source which heats the air inside the food chamber;
- a vent providing a path from inside of said food chamber to outside of said food chamber, for venting vapor, wherein said vent includes an upwardly sloping duct;
- a wet bulb temperature sensor in said food chamber, wherein said wet bulb temperature sensor lies adjacent to said upwardly sloping duct to receive condensate from said duct;
- a dry bulb temperature sensor in said food chamber;
- a controller which controls said first and second heat sources based on signals received from said wet bulb temperature sensor and said dry bulb temperature sensor;
- and further comprising a coil wrapped around at least a portion of said wet bulb temperature sensor for wicking condensate from said duct to said wet bulb temperature sensor.
A thermalizer, comprising:
- a food chamber;
- an evaporator in fluid communication with said food chamber;
- a controller;
- a dry heat source controlled by said controller;
- a wet heat source controlled by said controller;
- a wet bulb temperature sensor located in said food chamber and in communication with said controller;
- a dry bulb temperature sensor located in said food chamber and in communication with said controller;
- a user input in communication with said controller to set the wet bulb temperature in said food chamber;
- a user input in communication with said controller to set the dry bulb temperature,
- wherein said controller controls the wet heat source and the dry heat source to reach the user input settings, and further comprising a vent from said food chamber to atmosphere, said vent having downwardly-sloping walls;
- wherein said wet bulb temperature sensor is located adjacent to said vent so as to receive condensate from said vent.
