Are a base frame 9, a housing 10, an organic waste drive device 11, a dissolution tank 12, and a discharge container 1.
3, heating device 14, exhaust device 15, control device 16
Etc.

The base frame 9 has a rectangular shape in a plan view, closes a lower opening of the cover 1, and has casters 17 for movement at four corners.

The housing 10 includes a processing tank 19, a casing 20, and a hood 21.

Processing tank (also referred to as lower case)
19 is a double tank, a pair of left and right side plates 23,
It comprises an inner peripheral plate 24 and an outer peripheral plate 25 which are substantially U-shaped. By the inner peripheral plate 24 and the corresponding portions of both side plates 23,
A drying tank 26 which opens upward and to the right side and into which organic waste is charged is formed. The inner peripheral plate 24, the outer peripheral plate 25, and the corresponding portions of the both side plates 23 define the periphery of the drying tank 26, That is, a substantially U-shaped indirect heating chamber 2 in side view for indirectly heating the inside of the drying tank 26 forward, downward, and rearward.
7 are configured. On both left and right sides of the indirect heating chamber 27, baffle plates 28 are alternately protruded inward from the side plates 23 in the vertical direction, and the upper end of the indirect heating chamber 27 is the upper end of the inner peripheral plate 24. At the left side of the closed portion, a discharge port 29 for discharging hot air is formed.

As shown in FIG. 12, on the inner surface of the drying tank 26, a composite functional layer 30 for preventing adhesion of substances and emitting far-infrared rays is formed (coated) over the entire surface. The composite functional layer 30 is made of, for example, a paint or the like, and has a thickness of 100 to 400 μm, preferably 200 to 300 μm. Composite function layer 30
Is composed of a lower layer 31 and an upper layer 32 located above the lower layer 31.

The lower layer 31 (also referred to as a lower layer, an inner layer, or a far-infrared radiation layer) 31 is heated, for example, to 20
It emits far infrared rays of about 1000 μm, preferably about 2.5 to 30 μm, and the thickness thereof is, for example,
The thickness is 5 to 30 μm, preferably 5 to 15 μm. The lower layer 31 emits far-infrared rays at the time of heating, and a material having heat resistance is used.
Preferably, hard and high strength, wear resistance, chemical resistance,
A material having electric insulation and weather resistance, and having low water absorption and water permeability is used. In the embodiments, for example, ceramics are used as the material having all the above characteristics. As ceramics, manganese dioxide, chromium oxide, iron oxide, cobalt oxide, copper oxide, zirconia, alumina, silica, zircon, titania, aluminum titanate, cordierite, aluminum silicate, aluminum paste, etc., alone or Used, mixed.
The lower layer 31 may also have a function of preventing a substance from adhering, as described below. In this case, the constituent material of the upper layer 32 is added to the above material.

The upper layer (also referred to as an upper layer, a surface layer, or an adhesion preventing layer) 32 prevents adhesion of a substance such as organic waste, and has a thickness of, for example, 70 to 395.
μm, preferably 170 to 295 μm.
The reason why the thickness of the upper layer 32 is increased in this way is that the upper layer 32 is to be used for many years in consideration of abrasion due to the treatment of the organic waste. For the upper layer 32, at least a material having non-adhesiveness, release properties, and heat resistance is used. Further, preferably, the material also has chemical resistance, a low coefficient of friction, electric insulation, weather resistance, and water absorption. And a material with low water permeability is used. As a material having all the above characteristics, a fluororesin or the like is used. As fluororesin,
For example, polytetrafluoroethylene (used in Examples, for example, Teflon manufactured by DuPont is used), copolymerized fluororesin, polychlorotrifluoroethylene, polyvinylidene fluoride, and the like are used.
Examples of the copolymerized fluororesin include, for example, a tetrafluoroethylene-hexafluoropropylene copolymer, an ethylene-tetrafluoroethylene copolymer, a tetrafluoroethylene-perfluoroalkylvinyl ether copolymer, and an ethylene-chlorotrifluoroethylene copolymer ,
Tetrafluoroethylene-hexafluoropropylene-
A perfluoroalkyl vinyl ether copolymer or the like is used. Note that the upper layer 32 may further have a function of emitting far-infrared rays.
The material of the lower layer 31 is added.

The lower layer 31 and the upper layer 32 are formed (coated) simultaneously or separately on the inner surface of the drying tank 26. When the lower layer 31 and the upper layer 32 are formed at the same time, for example, alumina, silica, fluorine resin (fluoro)
Inorganic (inorganic filler) -organic hybrid heat-resistant paint mainly comprising This paint is a one-part slurry with a pH of 2, black or gray, and a viscosity of 500
１1500 cp. At the time of painting, the paint is stirred for each container containing the paint, and water is added as necessary.
Further, after performing an alkali degreasing treatment or an empty baking (400 ° C. × 10 minutes) treatment on the inner surface of the drying tank 26, a paint is applied by spraying or brushing. next,
After performing the temporary curing process (100 ° C. × 10 minutes), the main curing process (380 ° C. × 10 minutes) is performed to form the composite functional layer 30. In this case, since alumina and silica have a higher specific gravity than the fluororesin, a lower layer 31 in which alumina and silica are the main components and the fluororesin is mixed is formed below the composite functional layer 30, On the composite functional layer 30, an upper layer 32, which is a concentrated film of a fluororesin, is formed. The composite functional layer 30 has excellent properties as described in the description of the lower layer 31 and the upper layer 32, and has flexibility and small porosity as compared with a mere inorganic coating film.
Excellent surface smoothness and heat resistance (eg, up to 35 ° C for ordinary 300 ° C)
(Up to 0 ° C), high hardness, and low adhesion of ice during freezing. Furthermore, the composite functional layer 30 is excellent in boiling water resistance, impact resistance, bending resistance, salt spray resistance, water release, adhesion to the inner surface of the drying tank 26, and the like. In addition, since the lower layer 31 contains a fluorine resin which is a material component of the upper layer 32, even if the upper layer 32 is peeled, the adhesion preventing effect can be maintained to some extent. However, the upper layer 32 becomes a thickened film of a fluorine resin, and contains no or almost no alumina or silica as a material component of the lower layer 31. Therefore, the releasability and the non-adhesiveness of the upper layer 32 are not or hardly hindered by the surface of the upper layer 32 being roughened by alumina, silica or the like. Therefore,
There is no or little possibility that the adhesion preventing effect of the upper layer 32 will be hindered.
