8 shows an example in which the pulverizer assembly 130, which is more compact than the structures of FIGS. 6 and 7, has a driving motor capacity of about 500 W. FIG.

Since the bearing supporting the drive shaft 101, the seal, and the bearing cap for fixing the bearing are not removed at one side of the conveying screw 100 adjacent to the crushing part 110, there is no problem of sealing the bearings contacting moisture, There is a disadvantage in that it is necessary to change the structure when the pulverizing cutter 160 is caused to flow due to an increase in the amount of waste treatment.

On the other side, there is an advantage that the supporting bearing and the sealing seal of the crushing unit 110 can be removed stepwise without changing the structure of the crusher according to the load adjustment.

9 is a plan view of the planetary gear set 210 in which the magnetic clutches 212 and 213 are installed between the two driving gears 213 and 214 and the two planetary gears 210 and 211 in the reduction gear of the present invention, An example of a control element and a control flowchart of a control device that enables automatic control or unattended operation by setting the load current and the timer time to the optimum operation state.

For example, the signal output from the overload cut-off switch and the load current meter (ammeter) provided in the drive motor control board and the on-off time signal of the timer are applied to the clutch clutch power supply circuit. A design for minimizing the starting current of the driving motor 140 and consequently lowering the installation capacity of the driving motor 140 by delaying the supply of the garbage to the crushing unit 110 for a predetermined time This enables economical operation and efficient management. Automatic control is also possible to reduce energy loss due to long idling.

The setting time of the magnet clutch setting time of 30 seconds and the screw driving time of 5 minutes shown in the control flow chart is an example of 500 W class in which the food garbage that occurs on a day in the kitchen of a general house is relatively small. The set time can be freely increased or decreased.
