Food preparation apparatus and associated methods. In one method, dough is proofed in an oven compartment and then baked in the same oven compartment. Temperature and/or humidity can be controlled during proofing and/or baking cycles. A blower may be used, for example, to exhaust gas to ambient to reduce heat and/or moisture in the compartment. For example, the blower may be used between proofing and baking cycles to prepare an environment in the oven compartment for the baking cycle.

A system for processing dental prostheses that can efficiently manage multiple prostheses and multiple milling machines includes an input unit into which commands for operating functions of the dental prosthesis processing system are input; a display unit configured to display states of prostheses processed in the dental prosthesis processing system and milling machines used in the dental prosthesis processing system; a calculation and control unit equipped with CAM software and configured to control the milling machines according to a command input of a user via the input unit and fabricate a prosthesis; and two or more milling machines configured to process a workpiece into a shape of a prosthesis according to a command from the calculation and control unit and transfer their own state information to the calculation and control unit.
