A coffee grinder which has several different automatic grinding capacities is connected to a coffee brewer which has several different automatic brewing capacities by a control that inhibits brewing of all but the corresponding brew capacity following grinding of a quantity of coffee. The grinder is also inhibited from grinding any more coffee until the appropriate brew cycle of the coffee brewer is started. Once the corresponding brewing cycle is selected, the coffee grinder is reset and any grinding capacity may be selected. A calibration mode for the coffee grinder and the coffee brewer is provided wherein the duration of the grinding cycle or brewing cycle, respectively, is set by manually initiating the cycle and then halting of the cycle when the appropriate capacity is reached. The duration of the cycle is then set for subsequent automatic operation.

A microprocessor controlled food treatment/holding apparatus has a cabinet which defines a storage space for food to be treated at a predetermined temperature and relative humidity within said storage space, a heater with a surface that can be heated to a temperature which is sufficient to boil water for a predetermined length of time, and a controlled solenoid for delivering a plurality of preselected amounts of water against the heater surface according to the length of time a cabinet door is opened. Detailed operating parameters for the storage space of the temperature and relative humidity conditions are maintained in suitable memory and polled by the microprocessor during operation of the apparatus as real-time data from remote sensors are sent to the microprocessor, which controls the monitoring system of the apparatus. Separate and independent control logic exist for an initial pre-heat mode of operation, as well as for a normal operating mode of the apparatus for the cabinet door being opened and for the cabinet door being unopened for an extended period of time. Also disclosed is a method for controlling the temperature and relative humidity of a storage spaced within a cabinet apparatus used for treating and holding prepared food prior to serving.

A microcomputer controlled cooking apparatus and method including a plurality of presettable time and temperature circuits which allow for the programming into a cooking device of ideal cook time and temperature data. A microcomputer continuously monitors actual cooking conditions and automatically adjusts the cooking time of a food item in accordance with variations in temperature. These adjustments are computed in reference to an optimum temperature/time curve.
