When the dryer is heated, burning rupture occurs from the inner wall of the drying housing 51, and the drying screw 52 is pressed against the inner wall of the drying housing 51, And the food garbage burned noodles, which have been produced by rotating the laundry, are separated from the inner wall of the drying housing and are then turned over again.

The drying screw 52 is provided at its one end with a crushing cutter 52c engaged with the side wall cutter 51s so that the food waste moves toward the side wall cutter 51s along the rotating direction of the drying screw 52, And is crushed by the interaction of the cutter 52c and the side wall cutter 51s.

That is, the drying screw 52 is rotated by driving the driving means (not shown), but the rotating direction can be adjusted clockwise or counterclockwise. The food waste is moved to the closed end side of the drying housing 51 by the rotation of the drying screw so that the food waste is crushed by the interaction between the crushing cutter 52c and the side wall cutter 51s When the food garbage is to be discharged, the food garbage is rotated in the opposite direction to move the food garbage toward the discharge port 51o.

In the drying device 50 configured as described above, it is preferable that the drying screw 52 is formed so as to be directed toward the discharge port 51o and gradually increase the distance between the transfer blades 52w. The distance between the feed blades 52w is narrowed toward the side wall cutter 51s so that the food waste conveyed by the rotation of the drying screw when the food waste is crushed is more strongly pressed by the narrowed feed vane 52w, When the food garbage is discharged, the interval between the feed blades 52w becomes gradually widened, so that the food garbage that has been agglomerated is pressurized and pulverized and can be easily discharged to the discharge port 51o.

Also, it is preferable that at least one heater 53 is installed on the side wall of the drying housing 51.

The drying means 50 is for removing water remaining in the food waste which has been pulverized and dewatered by the pulverizing and dewatering means 10 and pulverizing the pulverized pulverized material. Since the drying efficiency is low at room temperature, (53) is further provided to increase the moisture drying efficiency by heating the drying housing (51).

The food waste disposal apparatus with improved drying function according to the present invention including the drying means 50 as described above is provided with the pulverizing and dewatering means 10 as described above and can be variously modified, Are configured as shown in Figs. 6 to 10.

That is, the pulverizing and dewatering means 10 includes two spindle housings 11 and 12 and one spindle screw 13 as shown in FIG. The two spindle housings 11 and 12 are referred to as a first spindle housing 11 and a second spindle housing 12 for ease of understanding and ease of explanation.

As shown in FIGS. 7 and 8, the first spindle housing 11 is formed in a cylindrical shape having a charging port 11i formed on an upper portion thereof, and at least one conveying cutter 11t is formed on an inner wall thereof.

As shown in FIG. 8, the feed cutter 11t is provided with a first spindle housing 11 on the inner wall in the longitudinal direction of the spindle housing, and grinds the food waste pushed by the rotation of the spindle screw 13 . That is, the food waste is pushed by the rotation of the spindle screw 13 and is crushed by the feed cutter 11t.

As shown in FIG. 7, the first spindle housing 11 is formed with a charging port 11i through which food waste is charged. The charging port 11i is formed at the upper end of the charging port 11i, as shown in FIGS. 1 and 2 So that the food waste supplied through the hopper is introduced into the first spindle housing (11).

A drain port (11w) is formed at the bottom of the first spindle housing (11) so that water discharged when the food waste is pressurized by driving the spindle screw (13) can be discharged.

The food waste to be pressurized and pulverized by the pulverizing / dehydrating means 10 contains a large amount of salt. When the water is pressurized by the pulverizing / dehydrating means 10, the dried food waste discharged therefrom contains a large amount of salt When food waste having such salinity is buried, salinity may leak and contaminate the soil. When the waste is reused as fertilizer, there is a problem that the crops are killed due to salinity.

Accordingly, in order to remove the salt from the food waste treated and dried by the food waste disposal apparatus of the present invention to have an environmental standard value of less than 1%, it is necessary to sufficiently remove the salt from the food waste supplied to the pulverizing / dehydrating means 10 It is preferable to further supply water.

The feed cutter 12t has a second spindle housing 12 formed on the inner wall in the longitudinal direction of the spindle housing in the same manner as the feed cutter 11t formed in the first spindle housing 11, The food waste transported by rotation is crushed. That is, the food waste is pushed by the rotation of the spindle screw 13 and is crushed by the feed cutter 12t. Of course, since the second spindle housing 12 has an inner diameter gradually narrowing toward the discharge port 12o, the transfer cutter 12t is also inclined toward the center of the second spindle housing.

In the inner wall of the discharge port 12o of the second spindle housing 12, at least one crushing cutter 12c is formed. The food waste pushed and transported by the spindle screw 13 is pressed and crushed by the interaction of the two spindle housings 11 and 12 and the spindle screw 13. However, The crushing cutter 12c is further formed inside the wall having the discharge port of the crushing cutter 12c.

As shown in FIG. 6, the spindle screw 13 is rotatably installed in a housing made up of two spindle housings 11 and 12 as described above. As shown in FIG. 6, the spindle screw 13 is gradually reduced in diameter from the first spindle housing toward the second spindle housing, the screw vane 13w is formed on the outer circumferential surface of the spindle screw 13, And a crushing cutter blade 13c is formed at the opposite end.

In addition, the spherical grooves 13r are formed to adjust the distance between the screw blades of the spindle screw 13 so that the connection between the screw blades and the housing has an arc shape, thereby preventing the food garbage being transported from being caught .

It is obvious that a driving means (not shown) such as a motor for rotating the spindle screw is installed on one side of the food waste disposal apparatus having the pulverizing / dewatering unit 10 constructed as described above, and a description thereof will be omitted.

A drain trap (30) connected to a sewage pipe is installed on the bottom of the drain hole (11w) so that the polluted water discharged in this way can be discharged to the drain without immediately flowing to another place.

The drain trap 30 may further include a deodorizing unit 40. Since the polluted water discharged through the drain trap (30) provides a good environment for the microbes to reproduce, it may be corrupted and odor may be generated, and in order to prevent the generated odor from diffusing into the space provided with the garbage disposer (40).

The deodorization means 40 may be made of activated carbon or the like.

A connection pipe 50p is installed at one side of the drying means 50. The connection pipe 50p is connected to the drain trap 30 to remove steam containing odors generated during drying of the food waste, So that it can be discharged to the outside through a drainage trap.

Of course, a blower 50b is disposed at one side of the drain trap to discharge air containing odor, and a U trap is connected to the middle of the drain trap to block the reverse flow of odor from the sewer pipe.

In addition, a gas outlet 51g is formed at one side of the upper portion of the drying housing 51 to connect a pipe for discharging odor and gas generated during drying of food waste, and is connected to a sewer pipe.

In addition, a collection box storage chamber 60 for collecting dry food waste discharged from the drying means 50 is formed in the lower portion of the drying means 50. As described above, the food waste discharged from the pulverizing / dehydrating means 10 is dried while passing through the drying means 50, and the dried food waste is discharged to the lower side of the drying means. In order to collect dried food waste discharged in this way, the collection box 60 can be detachably installed so that the collection box can be separated when the food waste is filled.
