As a result, the odor in the heating container is removed.

[0013]

FIG. 1 shows an embodiment of the present invention. In FIG. 1, the material to be dried 6 is housed in the heating container 1. At this time, the vacuum pump 2 is connected to the heating container 1, and the ozone storage container 3 is connected to the tip of the exhaust pipe of the vacuum pump 2. Here, an ozone generator 30 is built in the ozone storage container 3. The ozone storage container 3 is provided with a discharge port 7 for discharging the exhaust gas deodorized in the ozone storage container 3 to the atmosphere.

In addition to the exhaust pipe of the vacuum pump 2, a pipe 5 bypassing the vacuum pump 2 is connected to the ozone storage container 3, and an opening / closing valve 4 is installed in the pipe 5. On the other hand, the other end of the pipe 5 is connected to the heating container 1
And the vacuum pump 2 are connected to a pipe.

First, the material to be dried 6 is introduced from the charging port by opening the lid 10 of the heating container 1. Next, when performing vacuum drying, the vacuum pump 2 is operated to reduce the pressure inside the heating container 1 to a required pressure. In this state, the material to be dried 6 is heated by operating the heater. Although there are various types of heaters available, a microwave oscillator (magnetron) is used in this embodiment. The material to be dried 6 is heated to a microwave penetration depth by the dielectric heating of microwaves and its temperature rises. The material 6 to be dried thus heated reaches the boiling point temperature of the liquid determined by the reduced pressure environment in the heating container 1. In the case of water, this temperature is 100 ° C. or lower if the pressure inside the heating container 1 is 1 atm or lower. For this reason, the whole of the material to be dried 6 has a constant temperature, and the evaporation of the material to be dried 6 becomes more active as a whole. At this time, the generated water vapor is introduced into the ozone storage container 3 by the vacuum pump 2 through the vacuum pipe. On the other hand, the temperature of the material 6 to be dried, which has lost the latent heat due to evaporation, is lowered, and
It is heated by the above process, and evaporation is repeated.

On the other hand, the ozone storage container 3 is filled with the ozone generated by the ozone generator 30 before the vacuum exhaust. As a result, the odorous component introduced into the ozone storage container 3 can be oxidized and deodorized by the ozone filled in the ozone storage container 3. At this time, the odorous component generated together with the steam from the material to be dried 6 is introduced into the ozone storage container 3 by the vacuum pump 2 through the vacuum pipe together with the steam. At this time, the introduced odor component is oxidized and deodorized by the ozone filled in the ozone storage container 3. As a result, the odorous component exhausted by the vacuum pump 2 is deodorized in the ozone storage container 3, and when it is discharged from the ozone storage container 3 after the drying is completed, the odorous component is discharged in a removed state.

The material 6 to be dried, which has been heated by the above process and the water content has evaporated, gradually increases the degree of drying, and finally finishes the drying. In this process, it is possible to remove the odorous components in the exhaust gas introduced into the ozone storage container 3 by the vacuum pump 2 through the vacuum pipe,
The odorous components remaining in the heating container 1 cannot be removed. On the other hand, in the heating container 1 whose temperature has dropped to a safe temperature after the completion of drying, it is necessary to introduce outside air into the heating container 1 in order to take out the material to be dried 6 and return it to atmospheric pressure.

Therefore, in the process of introducing the outside air into the heating container 1, it is possible to remove the odorous components remaining in the heating container 1 by introducing the ozone filled in the ozone storage container 3. In order to enable this operation, the pipe 5 bypassing the vacuum pump 2 is connected to the vacuum pump 2
Installed on the path connecting the ozone storage container 3 and the heating container 1 (as close as possible to the vacuum pump 2) and the pipe 5
An on-off valve 4 for opening and closing the path of No. 2 was installed. This time,
During drying (while the heating container 1 is being evacuated by the vacuum pump 2), the on-off valve 4 is closed to prevent backflow of exhaust gas from the pipe 5 bypassing the vacuum pump 2 to the heating container 1,
After the drying is completed, the open / close valve 4 is opened in the process of introducing the outside air into the heating container 1, so that the ozone filled in the ozone storage container 3 is introduced into the heating container 1 through the exhaust pipe. As a result, the odorous components remaining in the heating container 1 are
Oxidized and deodorized by the introduced ozone, odor components are removed. For this reason, the lid 10 of the heating container 1 after the drying is completed.
Even when the heater is opened, the malodor in the heating container 1 is not released to the outside air.

According to this embodiment, by connecting the bypass pipe for opening to the atmosphere between the vacuum pump and the heating container, there is an effect that the deodorizing efficiency in the pipe is improved.

Next, another embodiment of the present invention is shown in FIG.
In FIG. 2, the configuration is the same as the embodiment in FIG. 1, but the difference from the embodiment in FIG. 1 is that the pipe 5 bypassing the vacuum pump 2 connected to the ozone storage container 3 is
This is the point directly connected to the heating container 1. Therefore,
The operation in the drying process is the same as that of the embodiment shown in FIG.

Next, after the drying is completed, the material 6 to be dried, which has been heated in the above-mentioned drying process and the water content is evaporated, gradually increases the degree of drying, and finally the drying is completed. In this process, similar to the embodiment shown in FIG. 1, it is possible to remove the odorous components in the exhaust gas introduced into the ozone storage container 3 by the vacuum pump 2 through the vacuum pipe, but the heating container It is not possible to remove the odorous components remaining in No. 1. On the other hand, also in this embodiment, in the heating container 1 whose temperature has dropped to a safe temperature after the completion of drying, it is necessary to introduce the outside air into the heating container 1 in order to take out the material 6 to be dried and return it to atmospheric pressure. is there.

Therefore, in the process of introducing the outside air into the heating container 1, by introducing the ozone filled in the ozone storage container 3, it becomes possible to remove the odorous components remaining in the heating container 1. In order to enable this operation, the pipe 5 bypassing the vacuum pump 2 is installed in the path connecting the heating container 1 and the ozone storage container 3, and the pipe 5
An on-off valve 4 for opening and closing the path of No. 2 was installed. This time,
During drying (while the heating container 1 is being evacuated by the vacuum pump 2), the opening / closing valve 4 is closed so that the heating container 1 from the pipe 5 is closed.
The exhaust gas is prevented from flowing back to the heating container 1, and the open / close valve 4 is opened in the process of introducing the outside air into the heating container 1 after completion of the drying, so that the ozone filled in the ozone storage container 3 is directly introduced into the heating container 1. To do. As a result, the odorous component remaining in the heating container 1 is oxidized and deodorized by the introduced ozone, and the odorous component is removed. Further, when the ozone is introduced into the heating container 1, the vacuum pump 2 is simultaneously operated to form a loop connecting the heating container 1 and the ozone storage container 3, so that the inside of the exhaust pipe can be deodorized. Becomes
Furthermore, a large amount of ozone can be introduced into the heating container 1 by the circulation loop. Therefore, as in the embodiment of FIG. 1, even when the lid 10 of the heating container 1 is opened after the drying is completed, the malodor in the heating container 1 is not released to the outside air.

According to this embodiment, since a loop connecting the heating container and the ozone storage container is formed, a large amount of ozone can be introduced into the heating container by the circulation loop, and the deodorization efficiency in the pipe and the entire system can be improved. There is an effect that can improve.

Next, FIG. 3 shows another embodiment of the present invention. In FIG. 3, the material to be dried 6 is housed in the heating container 1. At this time, the exhaust fan 21 is connected to the heating container 1, and the ozone storage container 3 is connected to the tip of the exhaust pipe of the exhaust fan 21. Here, the ozone storage container 3
The ozone generator 30 is built in. A pipe 5 bypassing the exhaust fan 21 is connected to the ozone storage container 3 in addition to the exhaust pipe of the exhaust fan 21.
An on-off valve 4 is installed in the. On the other hand, the other end of the pipe 5 is directly connected to the heating container 1.

First, the material to be dried 6 is introduced from the charging port by opening the lid 10 of the heating container 1. Next, when performing vacuum drying, the material to be dried 6 is heated by operating the exhaust fan 21 and the microwave oscillator. 6 to be dried
Is heated to a microwave penetration depth by microwave dielectric heating and its temperature rises. The material 6 to be dried thus heated reaches the boiling point temperature of the liquid in the heating container 1 at atmospheric pressure. This temperature is in the case of water, heating container 1
If the internal pressure is about 1 atm, it is about 100 ° C. Therefore, the whole of the dried object 6 has a constant temperature, and the dried object 6
Is more active in evaporation. At this time, the generated water vapor is introduced into the ozone storage container 3 by the exhaust fan 21 via the exhaust pipe. On the other hand, the material 6 to be dried, which has lost the latent heat by evaporation, is lowered in temperature as a whole and is heated in the above process, and evaporation is repeated.

On the other hand, the ozone storage container 3 is filled with ozone by the ozone generator 30 before the start of the drying process. As a result, the odorous component introduced into the ozone storage container 3 can be oxidized and deodorized by the ozone filled in the ozone storage container 3. At this time, the odorous component generated together with the steam from the material to be dried 6 is introduced into the ozone storage container 3 by the exhaust fan 21 through the exhaust pipe together with the steam. At this time, the introduced odor component is the ozone storage container 3
It is oxidized and deodorized by the ozone filled inside. This allows
The odorous components exhausted by the exhaust fan 21 are deodorized in the ozone storage container 3, and when the odorous components are discharged from the ozone storage container 3 after the drying is completed, the odorous components are discharged in a removed state.

Through the above process, the material 6 to be dried, which has been heated and the water content has evaporated, gradually increases the degree of drying, and finally the drying is completed. In this process, it is possible to remove the odorous component in the exhaust gas introduced into the ozone storage container 3 by the exhaust fan 21 via the exhaust pipe, but to remove the odorous component remaining in the heating container 1. I can't.
On the other hand, in the heating container 1 whose temperature has dropped to a safe temperature after the completion of drying, it is necessary to deodorize in order to take out the material to be dried 6. Therefore, after the drying is completed, the ozone storage container 3
It is possible to remove the odorous component remaining in the heating container 1 by introducing the ozone filled therein. In order to enable this operation, a pipe 5 bypassing the exhaust fan 21 is installed in the path connecting the heating container 1 and the ozone storage container 3, and an on-off valve 4 for opening / closing the path of the pipe 5 is installed. . At this time, the backflow of the exhaust gas from the pipe 5 to the heating container 1 is prevented by closing the on-off valve 4 during the drying (while the heating container 1 is being exhausted by the exhaust fan 21), and the ozone is heated by the heating container after the drying is completed. By opening the on-off valve 4 while operating the exhaust fan 21 in the process of introducing the ozone into the heating container 1, the ozone filled in the ozone storage container 3 is introduced into the heating container 1. The flow of exhaust gas by the exhaust fan 21 at this time is in the direction of arrow 210, as in the case of drying. As a result, the odorous component remaining in the heating container 1 is oxidized and deodorized by the introduced ozone, and the odorous component is removed.
Therefore, even when the lid 10 of the heating container 1 is opened after the drying is completed, the malodor in the heating container 1 is not emitted to the outside air.

According to this embodiment, in addition to the effects of the embodiment shown in FIGS. 1 and 2, it is not necessary to use an opening / closing valve for vacuum, and therefore, there is an effect of reducing the cost of the heating / drying device.

When the exhaust fan uses a motor capable of rotating in the reverse direction, exhaust is sent in the direction of arrow 210 during drying, and when the inside of the heating container 1 is deodorized after the completion of drying,
By sending the air containing ozone in the opposite direction to the arrow 210, the inside of the heating container 1 can be deodorized. In this case, the pipe 5 and the on-off valve 4 are unnecessary.

Next, FIG. 4 shows another embodiment of the present invention. In FIG. 4, the material to be dried 6 is housed in the heating container 1. At this time, the exhaust duct 22 is connected to the heating container 1, and the ozone storage container 3 is attached to the tip of the exhaust duct 22.
Are connected. Here, an ozone generator 30 is built in the ozone storage container 3. Further, a pipe 5 bypassing the exhaust duct 22 is connected to the ozone storage container 3 separately from the exhaust duct 22, an opening / closing valve 4 is installed in the pipe 5, and an inlet of the pipe 5 on the ozone storage container 3 side. An ozone introduction fan 51 is installed in. On the other hand, the other end of the pipe 5 is directly connected to the heating container 1.

First, the material to be dried 6 is introduced from the charging port by opening the lid 10 of the heating container 1. Next, when performing vacuum drying, by operating the microwave oscillator,
The material to be dried 6 is heated. The material to be dried 6 is heated to a microwave penetration depth by the dielectric heating of microwaves and its temperature rises. The material 6 to be dried thus heated is
The boiling temperature of the liquid in the heating container 1 at atmospheric pressure is reached.
In the case of water, this temperature is about 100 ° C. if the pressure inside the heating container 1 is about 1 atm. For this reason, the whole of the material to be dried 6 has a constant temperature, and the evaporation of the material to be dried 6 becomes more active as a whole. At this time, the generated steam is introduced into the ozone storage container 3 via the exhaust duct 22 by the vapor pressure of the generated steam. On the other hand, the material 6 to be dried, which has lost the latent heat by evaporation, is lowered in temperature as a whole and is heated in the above process, and evaporation is repeated.

On the other hand, the ozone storage container 3 is filled with ozone generated by the ozone generator 30 before the start of the drying process. As a result, the odorous component introduced into the ozone storage container 3 can be oxidized and deodorized by the ozone filled in the ozone storage container 3. At this time, the odorous component generated together with the steam from the material to be dried 6 is introduced into the ozone storage container 3 through the exhaust duct 22 together with the steam. At this time, the introduced odor component is oxidized and deodorized by the ozone filled in the ozone storage container 3. As a result, the odorous component exhausted together with the water vapor due to the vapor pressure in the heating container 1 through the exhaust duct 22 is deodorized in the ozone storage container 3, and when it is discharged from the ozone storage container 3 after drying, the odorous component is discharged. Is discharged in the state where the is removed.

Through the above process, the material 6 to be dried, which has been heated and the water content has evaporated, gradually increases the degree of drying, and finally finishes the drying. In this process, the exhaust duct 22
Ozone storage container 3 due to vapor pressure in heating container 1 via
It is possible to remove the odorous components in the exhaust introduced into the. However, since the inside of the ozone storage container 3 is kept at a temperature lower than that of the heating container 1, ozone is naturally sent to the heating container 1 by the air flow from the ozone storage container 3 to the heating container 1, and the ozone is stored in the heating container 1. It is difficult to remove the remaining odorous components. Waiting, heating container 1 due to the difference in ozone concentration
Although there is ozone that diffuses into, the amount is small. On the other hand, the heating container 1 whose temperature has dropped to a safe temperature after completion of drying
The inside needs to be deodorized in order to take out the material to be dried 6. Therefore, after the drying is completed, the odorous component remaining in the heating container 1 can be removed by introducing the ozone filled in the ozone storage container 3. In order to enable this operation, a pipe 5 bypassing the exhaust duct 22 is installed in the path connecting the heating container 1 and the ozone storage container 3, and an on-off valve 4 for opening and closing the path of the pipe 5 is installed. Further, the ozone introduction fan 51 was installed at the inlet of the ozone storage container 3 side of the pipe 5. At this time, the on-off valve 4 is opened during drying (while heating the inside of the heating container 1 by the microwave oscillator).
Is closed to prevent backflow of exhaust gas from the pipe 5 to the heating container 1. In the process of introducing ozone into the heating container 1 after the completion of drying, the opening / closing valve 4 is opened while operating the ozone introduction fan 51 to introduce the ozone filled in the ozone storage container 3 into the heating container 1. As a result, the odorous component remaining in the heating container 1 is oxidized and deodorized by the introduced ozone, and the odorous component is removed. Therefore, even when the lid 10 of the heating container 1 is opened after the drying is completed, the malodor in the heating container 1 is not released to the outside air.

According to the present embodiment, in addition to the effect of the embodiment shown in FIGS. 1 to 3, the exhaust device can be omitted and replaced with a small ozone introduction fan, so that the cost of the heating and drying device can be reduced. Has the effect of reducing

Next, referring to FIG. 5, as an ozone generator 30 installed in the ozone storage container 3 in the embodiment shown in FIGS. 1 to 4, a specific example in which an ultraviolet lamp 31 is installed in the ozone storage container 3 is shown. Show.
