ABSTRACT:
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.
