In an electric milling machine, when a milling operation is completed, a milling prohibition timer is set. With the timer being set, the electric milling machine does not perform a milling operation until countdown of the timer ends and the timer is cleared even though the electric milling machine is instructed to perform the milling operation. Even when supply of electric power from an external power supply to the electric milling machine is stopped, countdown of the timer is continued by using electric power supplied from an auxiliary power supply within the electric milling machine.

A manual meat grinder is provided. The manual meat grinder includes a bottom cover and an upper cover. The bottom cover includes lower grinding teeth disposed at intervals, and the upper cover includes upper grinding teeth disposed at intervals. The upper cover covers the lower cover and is rotatably connected to the lower cover, so as to grind meat through cooperation of the upper grinding teeth and the lower grinding teeth. At least one of the bottom cover and the upper cover includes blocking components disposed at intervals, and the blocking components are correspondingly disposed at at least one of a periphery of the lower grinding teeth and a periphery of the upper grinding teeth. In this way, meat is prevented from moving toward edges of the manual meat grinder in a meat grinding process, so as to improve a meat grinding effect.
