As shown in FIG. 5, the deodorant 43 is built in the drain tank 42, and the odorous air from the food waste container 20 is deodorized by the deodorant 43 and then exhausted from the exhaust pipe 46. It The drain water collected in the drain tank 42 is
The water is drained to the outside from a drain pipe 45 having a drain valve 44.

According to the food waste processing apparatus of the present invention configured as described above, food waste is processed as follows.

The raw garbage thrown into the belt conveyor 4 from the hopper 2 is thrown into the crushing means 8 which is rotating at a high speed by the driving means 9 from the charging port 18 and is finely crushed. At this time, if a metal object such as a knife or a fork is accidentally mixed in the garbage, the metal detector 5 detects the metal object. Therefore, there is no possibility that the blade of the crushing means 8 will be damaged by a metal object. Since the belt conveyor 4 automatically stops at the same time as detecting the metal object, the lid 7 is opened and the metal object is taken out from the garbage during this period. After that, the input of food waste is restarted.

All the crushed food waste is stored in the food storage tank 20 through the opening 23. When a predetermined amount of crushed garbage is stored in the garbage storage tank 20 in this way, the lid 3 of the hopper 2 and the lid 19 of the charging port 18 are closed to seal the entire garbage storage tank 20. In this way, when the entire garbage storage tank 20 is sealed, the driving means 27
Thus, the stirring means 24 is rotated to rotationally stir the crushed food waste in the food waste storage tank 20.

At the same time, the blower 32 and the heater 36 are operated to supply air from the suction port 33 to the one and the other exhaust pipes 34 and 38. The air in one of the exhaust pipes 34 is heated to 100 ° C. or higher by the heater 36, and heats and dries the crushed food waste stored in the food waste storage tank 20. The steam generated by heating and drying the crushed garbage containing a large amount of water flows into the condensing pipe 40 from the opening 41 in the garbage collecting tank 20.

On the other hand, the room temperature air blown from the other exhaust pipe 38 into the space (S) between the garbage storage tank 20 and the casing 1 changes the temperature of the entire casing 1 including the garbage storage tank 20. After being lowered, it flows into the condensation tube 40 from the upper end 40A of the condensation tube. The reason why the air from the other exhaust pipe 38 flows into the condensing pipe 40 from the upper end 40A of the condensing pipe is that the amount of air blown into the space (S) is one exhaust pipe 3
This is because the amount of air blown from No. 4 into the garbage storage tank 20 is larger than that. That is, the internal pressure of the space (S) is higher than the internal pressure of the food waste container 20.

From the opening 41 of the garbage storage tank 20 to the condensing pipe 4
The steam that has flowed into 0 contacts the normal temperature air that flows in from the upper end 40A of the condensation tube in the condensation tube 40 and is cooled. As a result, the vapor is condensed and the water content is liquefied,
It becomes a water drop and falls from the condensing pipe 40 into the drain tank 42 and is accumulated therein. The air that has flown into the drain tank 42 together with the water droplets is deodorized by the deodorant 43 in the drain tank 42 and then exhausted from the exhaust pipe 46.

When the heating and drying of the crushed garbage is completed in this way, the operation of the apparatus is stopped, the lid 22 is opened, and the crushed garbage heated and dried from the garbage storage tank 20 is discharged from the discharge port 21. Take it out. Since the food waste storage tank 20 has a spindle shape, the crushed waste that has been heated and dried is collected in the central portion of the food waste storage tank 20 in which the discharge port 21 is formed.
Therefore, the crushed dust can be easily taken out from the raw garbage storage tank 20. The total volume of shredded waste is hopper 2
Compared with the volume of raw garbage when it was thrown in, it is significantly reduced as a result of being heated and dried.

The crushed waste that has been heated and dried is effectively used as fertilizer or incinerated. Incinerating crushed waste is also easy because it is dry. During the processing of crushed waste, the exhaust air is deodorized, so no odor is generated. Also, after processing, the crushed waste is heated to a high temperature,
Since it is dried, no odor is generated. Moreover, since the volume is greatly reduced, it is extremely easy after the post-treatment such as transportation.

[0030]

As described above, according to the present invention, a large amount of food waste produced from family restaurants, etc.
Efficient volume reduction can be performed without generating odor during and after the treatment. Therefore, if this device is installed for each food waste generation source such as a family restaurant, all the problems such as collection and storage of food waste are solved, and extremely useful effects are brought about.
