[0002]

2. Description of the Related Art Usually, in order to vacuum-dry food waste,
Items to be dried such as raw garbage that are hermetically sealed in the vacuum container are
The material to be dried is dried at a low temperature by being heated by a heat source such as a heater or microwave while the inside of the vacuum container is decompressed by the vacuum pump.
For example, Japanese Unexamined Patent Publication No. 61-197985 discloses a vacuum drying technique using microwaves. In this case, it is possible to directly dispose of garbage in the crushed state, which is directly contained in the container. With the inside of the container being depressurized, microwaves are radiated from the outside of the container, so that the kitchen waste is dried at a low temperature with its boiling temperature lowered.

[0003]

However, in the case of the above publication, the irradiation unevenness of microwaves on the object to be dried is not taken into consideration, and uneven heating due to the object to be dried, and hence unevenness in drying occurs. Is becoming
In addition to such a problem, since the material to be dried is directly contained in the container, it is not easy to take out the material to be dried after drying it from the container. Further, the above-mentioned publication does not take into consideration the drying process for the fluid material to be dried under a zero-gravity environment, and the fluid material to be dried in a floating state may flow into the vacuum pump.

A first object of the present invention is to dry an object to be dried in a good condition without causing heating unevenness and drying unevenness when the object to be dried is dried by microwave irradiation under reduced pressure. It is possible to provide a vacuum microwave heating and drying device that can be used. A second object of the present invention is, in addition to the first object, to provide a vacuum microwave heating / drying device in which it is easy to take out the dried material after drying. A third object of the present invention is, in addition to the first object, vacuum microwave heating and drying capable of drying not only a solid material to be dried but also a fluid material to be dried even in a zero gravity environment. The equipment is provided.

[0005]

And a microwave heating unit that irradiates microwaves in the direction of the object to be dried. Second above
In addition to such a basic structure, the object of (1) is achieved by providing a bag fixing mechanism for detachably fixing the bag to be dried accommodation container to the article to be dried container. The third object is to store a to-be-dried material inside the to-be-dried material in a donut shape, a lid that opens and closes an upper opening of the to-be-dried material storage container, and the to-be-dried material.

[0006]

The material to be dried put in from the outside is housed in a donut shape inside the container to be dried, and the inside of the container to be dried is decompressed by the vacuum pump. The microwave heating unit provided in the above is configured so that microwaves are evenly irradiated in the direction of the object to be dried. As a result, the material to be dried is evenly heated as compared with one-way irradiation of microwaves to the material to be dried, and therefore the material to be dried can be dried without causing unevenness in drying. Moreover, at this time, in the container to be dried, the portion directly irradiated with microwaves is made of a non-conductive and microwave-transparent material, and the portion indirectly irradiated with microwaves is microwave-reflected. When the material to be dried is configured as a material having excellent properties, the material to be dried is also heated by the microwave reflected inside the material to be dried container, so that the material to be dried can be efficiently dried.

In order to dry the material to be dried while being accommodated in the microwave-permeable material-containing bag, the bag to be dried is detachably fixed to the material-containing container to be dried. When the fixing mechanism is provided, it is possible to easily take out the dried material from the dried material storage container to the outside. Further, when the inside of the container to be dried is evacuated from the upper portion of the lid by vacuum, the lid has a hydrophobic porous membrane, a net deformation preventing cover for preventing deformation of the hydrophobic porous membrane due to vacuum exhaust, and a material to be dried. If a net-like damage prevention cover for preventing the hydrophobic porous membrane from being damaged by a substance is provided, the fluid-like substance to be dried is vacuum pumped without causing deformation or damage to the hydrophobic porous membrane. It can be dried while the inflow to the membrane is blocked by the hydrophobic porous membrane.

EXAMPLE A vacuum microwave heating and drying apparatus according to the present invention will be described below with reference to FIGS. 1 to 5. First of all,
That is, the vacuum microwave heating and drying apparatus according to the present invention used in a non-gravity environment will be described. FIG. 1 shows its basic configuration in one example. In this case, the vacuum microwave heating / drying apparatus generally includes, inside the microwave shielding housing 1, a to-be-dried material storage container 2 for housing the to-be-dried material 19 in a donut shape, the magnetron 3, and the waveguide 4. The microwave heating unit composed of the rotor blade reflector 5 and the rotor blade reflector drive unit 6 and the upper portion of the microwave shielding housing 1 are integrated with each other to open the opening of the material to be dried container 2 by the rotation support portion 1a. From a lid 7 that can be opened and closed freely, and a vacuum pump 10 that evacuates the inside of the object-to-be-dried container 2 through a flexible vacuum exhaust pipe 9 from a vacuum exhaust port 8 formed in a part of the lid 7. Basically it is structured.

More specifically, the material-to-be-dried container 2 has an inner cylinder 11 and an outer cylinder 1 which are concentrically arranged.
2, the lower part between the cylinders 11 and 12 serves as a bottom 13 for accommodating the material to be dried 19, and the upper opening of the inner cylinder 11 is covered with a covering member, so-called a raised bottom 14 Has been configured as. Further, the microwave heating portion is arranged in a predetermined direction below the raised bottom 14. As shown in the figure, in the microwave heating unit in this example, the microwave from the magnetron 3 is radiated toward the raised bottom 14 through the waveguide 4 and the microwave irradiation port 4a. The rotary blade reflection plate 5 of FIG. The rotor blade reflector 5 is rotationally driven by the rotor blade reflector drive unit 6 attached to the lower part of the raised bottom 14, whereby the magnetron 3
That is, the microwaves from 1 to 6 are evenly reflected and radiated through the side wall of the inner cylinder 11 to the material to be dried 19 contained in the material to be dried container 2. At that time, the side wall of the inner cylinder 11 is a non-conductive and microwave permeable material,
For example, the outer cylinder 1 is made of plastic or the like.
If the bottom 2, the bottom 13 and the raised bottom 14 are made of a material having a high microwave reflectivity, such as a metal, the microwave reflected by those portions without being absorbed by the material to be dried 19 will eventually Are those that can be effectively absorbed by the material to be dried 19. By the way, if the material to be dried 19 is directly accommodated in the material to be dried container 2, the material to be dried container 2 is
Not only is it difficult to remove from the container, but also the inside of the object-to-be-dried container 2 needs to be frequently washed. However, after fixing the opening of the bag 18 for storing an article to be dried made of a high molecular compound to the bag fixing support portion 15 provided in the article to be dried 2 container, the bag fixing clip 17 is used. The dried object 19 is placed in the dried object storage bag 18.
If is added, it becomes easy to take out the dried material 19 from the dried material storage container 2.

Now, the operation of the vacuum microwave heating and drying apparatus configured as described above and the drying process of the material to be dried 19 associated therewith will be described below. That is, first, in the state where the lid 7 is opened prior to the start of the drying process, the bag-to-be-dried 18 has a bag fixing support 15 and a bag-fixing clip 17 whose opening is in the container 2 to be dried. It is supposed to be fixed by. In this state, the material to be dried 19 is put into the material to be dried bag 18 from the outside. The lid 7 is closed after the object to be dried 19 is put in, and the object to be dried container 2 is hermetically closed by the rubber seal 27 provided at the lower end of the lid 7. In this state, the microwave shielding housing 1 as well. Since it is closed, leakage of microwaves to the outside is prevented. next,
By operating the vacuum pump 10 with the lid 7 closed, the inside of the material to be dried 2 is decompressed via the vacuum exhaust tube 9, and at this time, the bag fixing support portion 15 is provided. Since the air existing in the gap between the dried object storage bag 18 and the dried object storage container 2 is also exhausted from the air vent hole 16, the entire inside of the dried object storage container 2 is depressurized with a uniform pressure. It is a thing. After that, the microwave heating section is operated while the vacuum pump 10 is operating, but the microwave from the magnetron 3 is radially reflected by the rotating blade reflector 5 that is rotationally driven, and the microwave is also applied to the inner cylinder. The object to be dried 19 is irradiated through the side wall 11. At that time, the microwaves that have passed through the material to be dried 19 are reflected by the inner surface of the outer cylinder 12 and the surface of the bottom 13, and therefore, the material to be dried 19
It can be irradiated and absorbed. If microwaves are absorbed by the material to be dried 19, the water contained in the material to be dried 19 is heated by high frequency dielectric heating. However, since the surroundings are in a reduced pressure state, the water is evaporated at a low temperature. It is the beginning. This water vapor is constantly exhausted by the vacuum pump 10, so that the depressurized state in the dried material storage container 2 is maintained. At that time, harmful gas and odor generated from the material to be dried 19 are processed in the vacuum exhaust processing container 31, and are exhausted to the outside of the microwave shielding housing 1 in a cleaned state. Explaining the evacuation processing container 31, the evacuation processing container 31 is, as the evacuation processing container 31, adsorbed by an adsorbing material such as activated carbon depending on the type of the material to be dried, permeating a water tank or a chemical solution tank, or water,
Cleaning by spraying chemicals, physicochemical treatment with catalyst,
Decomposition treatment by heat or ultraviolet rays is considered.

As described above, the material to be dried 19 is dried. If the material to be dried 19 is sufficiently dried, the operation of the microwave heating section is stopped, but the vacuum pump 10 The vacuum evacuation by is to be continued. In this state, the temperature of the material to be dried 19 starts to decrease, but if the temperature is sufficiently decreased, the operation of the vacuum pump 10 is stopped and the pressure in the material to be dried container 2 is returned to the atmospheric pressure. It is supposed to be. The lid 7 is opened in a state of being returned to the atmospheric pressure, and the material to be dried 19 is taken out to the outside together with the material to be dried containing bag 18.

The basic structure and operation of the vacuum microwave heating / drying apparatus used in the non-gravity environment have been described above, but various other microwave heating units are conceivable. .. Here, the structure of another microwave heating unit will be described below. That is, FIG. 2 shows the configuration of another microwave heating unit, but in this case, the microwave heating unit is fixed to the microwave generator including the magnetron 3 and the waveguide 4 and the bottom 13. , And a microwave generator rotation drive unit 20 for rotationally driving the microwave generator, the whole of which is similar to the case of FIG.
The inner cylinder 11 is housed and arranged so as to be projected. As shown in the drawing, the microwave is directly radiated from the waveguide 4 in the direction of the specific side wall of the inner cylinder 11, but the waveguide 4 itself is rotationally driven by the microwave generator rotation driving unit 20. After all,
Microwaves from the microwave generator are sequentially and evenly applied to the material to be dried 19 through the side wall of the inner cylinder 11. FIG. 3 also shows another configuration of another microwave heating unit. As shown in the figure, the microwave heating unit includes a microwave generator including a magnetron 3 and a waveguide 4, and the microwave from the microwave generator is radiated uniformly in the radial direction toward the side wall of the inner cylinder 11 in a stationary state. The microwave reflecting and irradiating plate 21 is arranged so as to be housed and arranged in a state of projecting inside the inner cylinder 11 as in the case of FIG. The microwave generator is arranged below the inner cylinder 11 and the microwave reflection / irradiation plate 21 is arranged directly below the raised bottom 14. The microwave reflection / irradiation plate 21 reflects and irradiates the microwave toward the side wall of the inner cylinder 11. Therefore, the conical side surface is configured as a curved metal plate. When the microwave heating unit is activated, microwaves from the microwave generator are radially reflected by the microwave reflection irradiating plate 21 and are evenly radiated to the entire side wall surface of the inner cylinder 11 to be dried. The object 19 can be uniformly heated.

Although the vacuum microwave heating / drying apparatus used in the non-gravity environment has been described above, special circumstances need to be taken into consideration in the non-gravity environment. The material to be dried is placed in a floating state in a zero-gravity environment, but when the material to be dried is a liquid or a fluid,
This is because those liquids or fluids may flow into the vacuum pump. Therefore, when the vacuum is exhausted from the upper portion of the lid, it is necessary to prevent the fluid or liquid from flowing into the vacuum pump at the upper portion of the lid.
However, the vacuum exhaust port does not necessarily have to be provided in the upper part of the lid, and no matter what part is provided, it is sufficient to prevent the liquid or fluid in the floating state near the vacuum exhaust port from flowing into the vacuum pump. It has become. Here, the vacuum microwave heating / drying apparatus used in a weightless environment (outer space) will be described. FIG. 4 shows the vacuum microwave heating / drying apparatus in the case where a vacuum exhaust port is provided in the upper part of the lid. It shows the basic configuration of the lid in. As shown in the figure, the lid 7 is separable into an upper lid portion 22 and a lower lid portion 23, and the upper lid portion 22 and the lower lid portion 23 are normally in close contact with each other by a rubber seal 27. A hydrophobic porous film 24 made of a Teflon film or the like is arranged between them. At the time of vacuum evacuation by the vacuum pump, only the gas such as water vapor permeates through the hydrophobic porous membrane 24, but the permeation of liquid or fluid is blocked. However, if the hydrophobic porous film 24 is simply arranged, the deformation of the hydrophobic porous film 24 itself is unavoidable due to the vacuum exhaust suction force.
Moreover, damage to the hydrophobic porous membrane 24 itself due to collision of a sharp solid material to be dried in a floating state is inevitable. In consideration of these circumstances, in this example, the vacuum exhaust port 8 portion is formed in a tapered shape in order to diffuse the vacuum exhaust suction force, and a deformation prevention cover is provided in the vicinity of the hydrophobic porous film 24 on the vacuum exhaust port 8 side. 25 are provided. As a result, the hydrophobic porous film 24 itself is prevented from being locally deformed by the vacuum exhaust suction force, and moreover, the deformation prevention cover 25 is deformed more than a certain amount.
Is suppressed by. In addition, the damage prevention cover 2 is provided between the hydrophobic porous membrane 24 and the object-to-be-dried container 2 side.
When 6 is arranged, collision of the sharp solid dried object in the floating state with the hydrophobic porous membrane 24 is prevented. Therefore, considering the respective functions of the deformation prevention cover 25 and the damage prevention cover 26, they are reticulated,
In addition, it is desirable to be made of a material that has heat resistance and rigidity.

FIG. 5 shows a more specific structure of the vacuum microwave heating / drying apparatus used in a weightless environment (outer space). As shown in the figure, the structure of the microwave heating unit, the arrangement of the material to be dried container 2, and the like are almost the same as those described above. The major difference is that the lower part of the lid 7 is made to project in the direction of the object-to-be-dried container 2 to prevent the object-to-be-dried 19 from floating too much, and the vacuum exhaust pipe 9 is located below the object-to-be-accommodated container 2. This means that the object storage container 2 is also evacuated from the top and bottom so as to communicate with the vacuum exhaust port 30. The lower part of the lid 7 is formed in a donut shape and is projected toward the dried object storage container 2. The donut-shaped protruding portion has a hydrophobic porous film 24, a deformation preventing cover 25, and a damage preventing cover 26. Has been arranged. However, since it is difficult to open and close the lid 7 itself due to the protrusion of the lower portion of the lid 7, the lid 7 is once opened in a state of being lifted in the upper direction, and after being closed once in a state of being lifted. , It can be completely closed only by lowering it as it is. A positioning member 1c and a slide member 1b that allow only the vertical movement of the lid 7 itself are provided in the lower portion near the rotation support portion 1a that supports the lid 7 so that it can be opened and closed, and the microwave shielding housing 1. But
This allows the lid 7 to be opened and closed as described above. Further, in this example, the upper portion of the outer cylinder 12 is formed as a rounded bag-fixing support portion 15, and in order to fix the opening portion of the dried object storage bag 18 to this portion, it is provided on the lid 7 side. Rubber groove seal 28
Is engaged with the bag fixing support portion 15, so that the opening of the dried object accommodation bag 18 is fixed. The lower part of the lid 7 is made to project toward the object-to-be-dried container 2, but the lower part 23 of the lid is provided with a rubber O-ring 29 in order to prevent the floating of the object 19 to be dried. Has become.

Now, the operation of the vacuum microwave heating / drying apparatus as described above will be described. When the drying process is started, first, the bag 18 for holding the article to be dried is supported with the lid 7 opened. After being temporarily attached to the portion 15, the material to be dried 19 is put into the material to be dried containing bag 18. After the charging, the lid 7 is closed, so that the object-to-be-dried container 2 is kept in a hermetically sealed state. At this time, since the material to be dried 19 is in a floating state in a weightless environment, the donut-shaped lid lower portion 23 pushes the material to be dried 19 to the upper portion of the inner cylinder 11 through which microwaves pass, while the material to be dried 19 is covered via the O-ring 29. The dried material storage bag 18 and the dried material storage container 2 are in close contact with each other, and the dried material storage bag 18 is in a sealed state. Further, the bag fixing support portion 15
The groove-shaped seal 28 and the groove-shaped seal 28 are in close contact with each other while sandwiching the bag 18 to be dried, thereby further sealing the entire inside of the container 2 to be dried. After the lid 7 is closed, the vacuum pump 10 is operated to depressurize the object to be dried container 2, but at that time, air is also exhausted from the vacuum exhaust port 30. The whole is depressurized at the same pressure. After that, the microwave heating unit is operated and the drying process is performed. When the material to be dried 19 is sufficiently dried in time, the operation of the microwave heating unit is stopped, so that the temperature of the material to be dried 19 is gradually decreased.
The operation of is stopped. After that, the lid 7 is opened in a state where the inside of the dried object storage container 2 is returned to the external atmospheric pressure, and the dried object 19 together with the dried object storage bag 18 may be taken out.

[0016]

As described above, according to the first to sixth aspects, when the material to be dried is dried by microwave irradiation in a depressurized state, heating unevenness and drying unevenness do not occur. It is possible to dry the material to be dried in a good condition, and in the case of claim 7, it is easy to take out the material to be dried after drying.
According to the above, a vacuum microwave heating / drying apparatus capable of drying not only a solid material to be dried but also a fluid material to be dried even under a zero-gravity environment can be obtained.
