Abstract

(57) [Summary] [Purpose] To propose a drying device capable of efficiently drying kitchen waste without emitting offensive odors and the like to the surroundings. [Structure] A ribbon screw is installed in a heating cylinder having a heating device at its periphery so that its peripheral edge is slidably brought into contact with the inner surface of the heating cylinder, and the ribbon screw is rotated. A discharge port was provided, and an intake port was opened on the upper side surface of the heating cylinder. The garbage supplied to the bottom of the heating cylinder is conveyed along the inner surface of the heating cylinder by the ribbon screw,
The kitchen waste heated and dried by the side wall of the heating cylinder falls from the inner peripheral edge of the ribbon screw and accumulates at the bottom of the heating cylinder. The odorous vapor is sucked and discharged from the intake port and does not cause a bad odor in the surroundings.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a dryer for kitchen waste crushed by a disposer or the like.

[0002]

[Prior art]

 Heretofore, as this type of kitchen drying apparatus, Japanese Patent Laid-Open No. 3-278877 and Japanese Patent Laid-Open No. 64-27652 are known. Japanese Unexamined Patent Publication (Kokai) No. 3-278877 irradiates microwaves to raw garbage stored in a rotating drum, and Japanese Unexamined Patent Publication No. 64-27652 (1989) discloses a method of drying raw garbage as shown in FIG. Ribbon screws are used to convey dust.

[0003]

[Problems to be solved by the device]

 According to Japanese Patent Laid-Open No. 3-278877, a rotary drum is provided in the drying case to dry the raw garbage while moving it, so uniform drying is possible. However, when the raw garbage is supplied and the dried raw garbage is taken out, the operation is performed. I have to stop. Further, as shown in FIG. 8 of Japanese Patent Laid-Open No. 4-27652, the ribbon screw is used for drying while being conveyed by a ribbon screw. It is only used for transporting.

[0004]

[Means for Solving the Problems]

 In this device, a drying drum (heating cylinder) equipped with a heating device is provided upright on the circumference, and a ribbon screw provided in the heating cylinder conveys the garbage at the same time as the garbage being conveyed is appropriately collapsed. The purpose of this method is to provide uniform drying, and in the case of a roller, a heating cylinder provided with a heating device is provided upright on the periphery of the roller, and the outer peripheral edge of the roller is slidably in contact with the inner surface of the heating cylinder. In addition to the rotating ribbon screw, the bottom of the heating cylinder is provided with a garbage supply port and a dry garbage outlet, and an intake port is opened above the heating cylinder. When the ribbon screw requires a strong conveying force, the heating cylinder is formed in a truncated cone shape.

[0005]

[Action]

 The device according to the present invention is configured as described above, and the raw kitchen waste supplied to the bottom of the heating cylinder is lifted (conveyed) along the inner surface of the heating cylinder with the rotation of the ribbon screw and heated. The device evaporates and dries the water. Then, the garbage that has been conveyed upward and dried is pushed up by the subsequent garbage, and falls from the inner edge of the ribbon screen to the center of the heating cylinder. That is, the garbage that rises along the inner peripheral surface of the heating cylinder and is dried by the heating device falls into the center of the heating cylinder, and when the bag is operated, this drying cycle is repeated, and the drying condition is Can be adjusted easily. Also, when performing continuous drying operation, by providing a kitchen waste and a dry kitchen waste separating plate at the bottom of the heating cylinder, only the dried kitchen waste can be separated and taken out. In order to increase the (force), the heating cylinder may be formed in a trapezoidal shape, and by doing so, the garbage can be pressed against the inner surface of the heating cylinder to further improve the heat transfer efficiency. The present invention will be specifically described below with reference to the drawings.

[0006]

【Example】

 In the figure, reference numeral 1 is a heating cylinder provided with a low-frequency induction heating coil 2 on its peripheral wall, 3 is a ribbon screw provided so that its outer peripheral edge is in sliding contact with the inner surface of the heating cylinder 2, and 4 is a drive of the ribbon screw. Axis 5 is its drive motor. Next, reference numeral 6 is a hopper for supplying garbage, and reference numeral 7 is a supply screen in which the start end is exposed to the bottom of the hopper 6, and the end thereof is extended to the bottom of the heating cylinder 2. A screen 8a is stretched around the case 8 of the supply screw 7, and a pan 9 is provided below the screen.

A dry kitchen waste outlet 1a is provided on the bottom side wall of the heating cylinder 1, and an odor removing intake port 1b is provided on the upper side wall. Reference numeral 10 is an odor absorber provided so as to be connected to the intake port 1b. In the one shown in FIG. 1, the heating cylinder 2 is configured in the shape of a truncated cone to perform batch-type drying, but in the one shown in FIG. 2, the heating cylinder 2 is configured in the shape of an inverted truncated cone, A guide plate 1c is provided on the bottom of the discharge passage 1d to continuously take out the dried kitchen waste.

The kitchen waste drying device according to the present invention is configured as described above. Therefore, the kitchen waste thrown into the hopper 6 has its water content separated by the screen 8a while being fed by the supply screw 7. And is supplied to the bottom of the heating cylinder 1. Then, inside the heating cylinder 1, the ribbon screw 3 is driven to convey the material upward along the inner surface of the heating cylinder 1, and the inner surface of the heating cylinder 1 is heated by the low-frequency induction heating coil 2 during this time. Is heated and dried. Then, the dried garbage is pushed up by the undried garbage that follows, and at the upper part of the ribbon screw 3, it overflows from the inner edge of the ribbon screw 3 and falls through the hollow portion at the center thereof to be deposited on the bottom portion of the heating cylinder 1. Then, the kitchen waste dropped by continuing the operation is again conveyed upward by the ribbon screw 7 and heated and dried, and by repeating this, it is possible to obtain the kitchen waste having a desired dryness. In this case, if the heating cylinder 1c is formed in a truncated cone shape as shown in FIG. 1, the garbage feeding force by the ribbon screw 3 is strong, and the garbage should be brought into sufficient contact with the heating surface (inner surface) of the heating cylinder 1. The drying efficiency can be improved.

The above is the case of batch-type drying in which a fixed amount of garbage is supplied to the heating cylinder 1. However, in the apparatus shown in FIG. 2, the kitchen waste is continuously supplied and the dried garbage is removed. It is possible to take out continuously from the outlet 1d.

As described above, regardless of whether the drying is performed by the batch system or the continuous system, in the device according to the present invention, the evacuation part of the heating cylinder 1 from the garbage supply part to the drying kitchen extraction part is removed. It can be completely sealed and does not emit odor to the surroundings. Moreover, when a low-frequency induction heating coil is used as the heating source as shown in the figure, the heating temperature can be controlled more easily than with steam and the like, and a fully automatic operation can be performed.

[0011]

[Effect of device]

 As described above, the device according to the present invention treats the kitchen waste in a completely sealed state, does not emit a bad odor to the outside, and is capable of fully automatic operation. The drawbacks of the conventional device can be completely solved.
