An automatic
temperature control device for
solid fuel fired food
cooker fueled by wood,
charcoal, or other
solid fuels which is capable of operation with any type of
cooker without utilization of different sized blowers and conserves
solid fuel usage. The present invention serves to regulate cooking temperature by controlling or optimizing the amount of
combustion air reaching the fuel. The present invention also allows an outdoor barbecue grill or smoker of any reasonable size to be retrofitted with the invention in order to allow a chef to cook foods at stable and precise temperatures. The core components of the invention are an
air blower to provide
combustion air to the burning fuel, an
electronic controller to control the amount of air delivered by the
air blower via a unique
algorithm embedded within the
electronic controller, a temperature sensor to sense the temperature inside of the
cooker in the vicinity of the cooking food and provide feedback to the
electronic controller, and an air tube and air manifold to get or direct the
combustion air from the
air blower inside the blower box to the burning fuel inside the cooker. Alternative embodiments utilize an automatic
damper connected with said electronic controller whereby
convection air currents may be precisely controlled.
