Abstract

Abstract An automatic roux maker including a pot for heating and agitating (mixing and moving) the roux during the cooking process, in which a motor-driven agitator is included and suspended within the pot for mixing the roux during cooking and for preventing scorching of the roux. At the bottom of the centrally located agitator shaft is included, for example, two diametrically opposed, paddle arms which ride and sweep on the bottom of the pot and are pivotally connected to a slotted support which is capable of floating up-and-down with respect to the agitator shaft. The flexible sweeping of the bottom of the pot prevents any of the roux from remaining on the bottom of the pot for any significant period of time, preventing scorching of the roux. A timed thermostat driven controller utilizing the information from a thermostat sensor included within the pot maintains the temperature within the desired range for the desired period of time and also continues the rotation of the agitator shaft after the cooking cycle has been stopped until a lowered, set, safe temperature of the roux occurs, which prolonged agitation continues to prevent any scorching of the roux during the elevated portion of the cool-down cycle.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 308 words
An automatic cooker system for preparing a roux or the like, comprising: a cooking pot having a bottom and cylindrically shaped side walls; heat source means for heating and cooking fluid contents of said pot; agitator means associated with the pot for mixing and moving the fluid contents of said pot, said agitator means including a centrally located rotor shaft extending down to a position in juxtaposition to the pot bottom; at least one paddle arm located at the bottom of said rotor shaft and extending radially out from said shaft with its bottom edge in sweeping contact with the upper surface of the pot bottom; a floating connector connecting said paddle arm to said rotor shaft by means of a connection which allows said paddle arm to move up and down and to pivot in the axial plane with respect to said rotor shaft; and a powered motor attached to said rotor shaft for rotatively driving it to move said paddle arms in sweeping contact across the bottom of said pot; and controller system means associated with said agitator means and said heat source for controlling the amount and duration of heating energy supplied to said heat source for said pot and for automatically controlling the power to said motor, said controller system including temperature sensing means for sensing the temperature of the contents of pot; controller circuitry means associated with said temperature sensing means for controlling the heat level and duration of heating of said heat source to the pot until the desired set degree of color level of the roux is reached; and motor control circuitry means associated with said motor for maintaining the motor in operation while the roux is being cooked and for a significant period of time thereafter while the cooked roux is cooking down until a safe, lowered temperature is reached.
Claim 2
Dependent Claim 308 words
An automatic cooker system for preparing a roux or the like, comprising: a cooking pot having a bottom and cylindrically shaped side walls; heat source means for heating and cooking fluid contents of said pot; agitator means associated with the pot for mixing and moving the fluid contents of said pot, said agitator means including a centrally located rotor shaft extending down to a position in juxtaposition to the pot bottom; at least one paddle arm located at the bottom of said rotor shaft and extending radially out from said shaft with its bottom edge in sweeping contact with the upper surface of the pot bottom; a floating connector connecting said paddle arm to said rotor shaft by means of a connection which allows said paddle arm to move up and down and to pivot in the axial plane with respect to said rotor shaft; and a powered motor attached to said rotor shaft for rotatively driving it to move said paddle arms in sweeping contact across the bottom of said pot; and controller system means associated with said agitator means and said heat source for controlling the amount and duration of heating energy supplied to said heat source for said pot and for automatically controlling the power to said motor, said controller system including temperature sensing means for sensing the temperature of the contents of pot; controller circuitry means associated with said temperature sensing means for controlling the heat level and duration of heating of said heat source to the pot until the desired set degree of color level of the roux is reached; and motor control circuitry means associated with said motor for maintaining the motor in operation while the roux is being cooked and for a significant period of time thereafter while the cooked roux is cooking down until a safe, lowered temperature is reached.
Claim 3
Dependent Claim 39 words
The cooker system of claim 1, wherein said motor control circuitry is operationally interconnected with said temperature sensing means sensing the point in time when the safe, lowered temperature is reached and cutting off the power to said motor.
Claim 4
Dependent Claim 36 words
The cooking system of claim 1, wherein said controller circuitry means further includes three setting point means producing three different color levels of roux, said setting point means affecting the amount of cooking of the roux.
Claim 5
Dependent Claim 71 words
The cooking system of claim 1, there is included at least two diametrically opposed paddle arms, and said connection includes a connector plate connected to said paddle arms by means of pivot pins; said connection further including a pin connection to said shaft fitting through a centrally located vertical slot in said connector plate, allowing said connector plate with its pivot connections to said paddle arms to move up and down.
Claim 6
Dependent Claim 19 words
The cooking system of claim 1, wherein there is included at least one pair of diametrically opposed, paddle arms.
