Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste processing apparatus for processing food waste generated in, for example, a cafeteria or a home to reduce the volume to form fertilizer.

[0002]

In order to efficiently treat raw garbage, a pretreatment machine for crushing and drying raw garbage is installed at a stage prior to the raw garbage treating machine to crush and dry the raw garbage. After that, it is thrown into the garbage processing machine and processed.
The processing drum for crushing and drying the raw garbage of the pre-processing machine is operated by changing the posture appropriately to the drum posture adapted to each work such as loading, crushing and drying of raw garbage, and discharging after drying. At this time, the rotation motor of the drum, the opening / closing motor of the drum lid, the crushing and stirring motor provided in the drum,
If any one of the blowers for feeding dry air is mounted on the pedestal side that supports the drum in a freely changeable posture, the connection of the drive system and piping system with the drum side becomes complicated. In addition, damage is likely to occur between the connections.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, there is provided a drum rotation motor for rotating a processing drum for charging food waste, and a lid opening / closing motor for opening / closing a lid for closing a food waste input port of the drum. A cutter rotation motor that rotates a cutter that crushes and stirs food waste in a closed drum, and a blower that feeds drying air into the closed drum, and each motor and blower in a machine frame that supports the drum. Is integrally provided, and the machine frame is tiltably provided on the gantry. When the drum posture is changed, the motor and the blower are also tilted integrally with the drum, and the motor and the blower between the drum and By keeping the relative relationship between the drive system and the piping system constant, it is possible to make these structures compact and improve the durability.
