Here, since the drying apparatus using combustion heat uses gas fuel, liquid fuel, or the like, the entire apparatus becomes complicated and large, and there is a problem in safety. Microwave-based drying treatment equipment is suitable for drying of high-moisture content materials to be dried because microwaves are selectively absorbed by moisture in the material to be dried.
There are some difficulties in controllability. On the other hand, a drying treatment device using an electric heater has excellent safety and controllability,
It is easy to reduce the size and cost of the device.

[0003]

However, the above-mentioned conventional drying apparatus using an electric heater also has the following problems. That is, to heat the object to be dried by heat conduction, it is difficult to uniformly dry the object to be dried,
In many cases, the object to be dried adhered to the heating surface or the object to be dried at a position distant from the heating surface was insufficiently dried.
In particular, since the inside of the object to be dried is heated by heat conduction from the surface, the larger the object to be dried, the more prone to uneven drying. In addition, water vapor generated from the material to be dried may condense after being discharged, and may contaminate the inside and outside of the room.

An object of the present invention is to provide a drying apparatus capable of improving the uniformity of the drying processing and the condensation performance of water vapor generated from the material to be dried, in consideration of the conventional problems as described above. It is.

On the other hand, at the upper end of the object-to-be-dried storage section 2, a roller 28 is provided as a rotation assisting tool for rotating the object-to-be-dried 2, in contact with the inner surface of the cylindrical heat-insulating container 3. An inner container ring 29 is provided on the upper part of the object storage unit 2 so as to reduce the inner diameter of the opening. A condensed water outlet 30 is provided at a lower end of the condensing part 4, and a condensed water discharge passage 34 is attached to the condensed water outlet 30 in a downward direction. In the middle of the condensed water discharge passage 34,
A gas suction pipe 32 is connected to suck gas (including odor) generated from the gas. The gas suction pipe 32 is connected to a catalyst device 33 for absorbing odor and the like in the gas, and the catalyst device 33 is connected to the intake fan 31 for sucking the gas.

Next, the operation of the above embodiment will be described.

First, the condensing section lid 6 is opened and the object 1 to be dried is put into the object storage section 2, and then the condensing section lid 6 is closed. Thereafter, when the upper heater 7 is operated, the air around the heated upper heater 7 gradually moves downward, and starts heating the object 1 from above. On the other hand, when the lower heater 26 is also operated, the object-to-be-dried 2 is heated, and the object to be dried 1 starts to be heated from below by heat conduction. Dry matter 1
When the temperature rises, steam 9 is generated, and the object 1 is dried. At this time, the temperature control of the upper heater 7 is performed based on the detection result of the upper temperature detector 11, and the temperature control of the lower heater 26 is controlled by the lower temperature detector 27.
Is performed based on the detection result. Also, the upper heater 7,
By activating the motor 16 together with the lower heater 26 and rotating the object-to-be-dried 2 in an inclined state, the object 1 to be dried is crushed into small pieces by the crushing blade 5. Since the inside of the object to be dried 1 is heated by heat conduction from the surface,
By crushing the dried object 1 into small pieces, heat can be effectively transmitted to the inside of the dried object 1, and uniform drying can be promoted. The effect of this pulverization is
Is remarkable when inclined by 40 to 90 degrees with respect to the vertical plane. By applying the Teflon coating to the inside of the storage portion 2 for drying object, the adhesion of dirt can be suppressed and the washing becomes easy.

On the other hand, the upper heater 7 and the lower heater 2
6. Activate the blower fan 12 together with the motor 16,
The outer surface of the condenser 4 is air-cooled. By cooling the outer surface of the condenser 4 by air, most of the water vapor 9 generated from the object 1 is condensed on the inner surface of the condenser 4 to form condensed water 20, which is discharged from the condensed water outlet 30 at the lower end of the condenser 4. . Condensate outflow section 3
From 0, solids that would cause clogging in the sewer path are not discharged, so that there is no adverse effect on the environment. Gas (including odor) generated from the object 1 to be dried
Is sucked by the intake fan 31 to remove the odor by passing through the catalyst device 33,
To the downstream side of

As described above, by disposing the cylindrical heat-insulating container 3 between the object-to-be-dried storage section 2 and the condenser section 4,
It is possible to suppress heat radiation from the object 1 to be dried, and to achieve high efficiency. That is, if the air cooling on the outer surface of the condensing part 4 is strengthened in order to enhance the condensing performance, the heat loss from the object 1 to be dried tends to increase.
It is possible to achieve both improvement in condensation performance and high efficiency.

When the drying object storage unit 2 is continuously rotated, the drying object 1 easily adheres to the inner surface of the drying object storage unit 2 and the crushing blade 5. By intermittently rotating the object, it is possible to suppress the adhesion of the object 1 to the inner surface of the object storage portion 2 and the crushing blade 5.

(Embodiment 2) FIG. 2 is a sectional view of a drying apparatus according to Embodiment 2 of the present invention. 2, the difference from the first embodiment is that the crushing blade 5 is provided not only on the inner side surface of the object-to-be-dried storage unit 2 but also on the inner bottom surface of the object-to-be-dried storage unit 2.
Is fixed.

By fixing the crushing blade 5 also to the inner bottom surface of the object storage section 2, adhesion of the object 1 to the inner bottom surface is suppressed and the object 1 is moved in a certain direction (the object to be dried). It can be rotated not in the direction of rotation of the storage section 2) but in multiple directions, and can be crushed into small pieces.

(Embodiment 3) FIG. 3 is a sectional view of a drying apparatus according to Embodiment 3 of the present invention. In FIG. 3, a difference from the first embodiment is that a plurality of pins 35 are fixed to the inner bottom surface of the drying object storage unit 2 in order to attach and detach the grinding blade 5 from the drying object storage unit 2, and the inside is crushed. The pin hole of the crushing blade ring 36 having the blade 5 is inserted into the pin 35 so that the crushing blade ring 36 is attached to the inside of the drying object storage unit 2. Here, the material of the crushing blade ring 36 does not need to be limited to metal.

As described above, the washing of the crushing blade 5 is facilitated by attaching and detaching the crushing blade ring 36 from the object-to-be-dried storage section 2. In addition, since a plurality of crushing blades 5 can be integrated, handling becomes easy.

In the above-described embodiment, the rotation is used to move the object-to-be-dried accommodating section, and the motor 16 is used as the driving means. However, the present invention is not limited to this, as long as the object to be dried and the heated steam can be stirred. For example, vibration may be used for the movement, and a vibration device or the like may be used for the driving unit.

Further, in the above embodiment, the cylindrical heat insulating container 3 made of a metal container whose inside is decompressed is used as the heat insulating member. However, the present invention is not limited to this, and another heat insulating member may be used.
Alternatively, there is no particular need.

In the above embodiment, a normal heater is used as the heating means. However, the present invention is not limited to this. For example, a ceramic heater, an infrared lamp, or the like may be used.

Further, in the above embodiment, the attaching / detaching means is constituted by the plurality of pins fixed to the inner bottom surface of the object-to-be-dried and the crushing blade ring insertable into the pins. If it is detachable, it may be constituted by another method.
