DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to household garbage which is suitable for household foods requiring drying treatment, cooking waste containing a relatively large amount of water, garbage generated in the kitchen such as leftovers, and the like. those concerning the <br/> processing equipment.

[0002]

2. Description of the Related Art Reduction of food and prevention of spoilage by drying are
It has been widely used as a method for preserving food. The method for drying the food includes, in addition to solar drying using sunlight, drying treatment using equipment for drying, for example, a heater drying method, a hot air drying method, a microwave drying method, a freeze drying method, and a spray drying method. Etc. The method using these devices plays a significant role in the field of food preservation because the food can be dried more quickly than the solar drying method.
In addition, with the recent rise of social environmental conservation, it has been desired to reduce the amount of garbage generated at home as well as food and to prevent rot, etc. From the viewpoint of environmental protection, the reduction of garbage is being promoted socially. Therefore, a method has been devised in which garbage is dried in the same manner as food to prevent weight loss and rot.

[0003]

However, in spite of the fact that there are many drying processing apparatuses in the industry, there are almost no apparatuses for easily drying food at home. Also, the drying method used industrially,
When applied to a home drying device, each presents many problems. For example, in the drying method using microwaves, it is very difficult to dry uniformly when the microwaves exist in a small space because of the intensity distribution of the microwaves.
In the drying method using a heater, a long drying time is required if the drying temperature is set low to prevent overheating and ignition. Further, in any of the drying methods, stains are generated in the apparatus in the drying process, but measures for preventing the contamination have not been sufficiently studied. When using the device for home use, the sample to be dried tends to be unspecified, especially,
When producing a dried product utilizing characteristics such as the fragrance of each sample, it is important that there is little contamination in the apparatus.

[0004] The present invention, which in view of the prior such issues, performs uniform drying, against corruption, and an object thereof is to provide a garbage disposal equipment capable of reducing the contamination of the device is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing embodiments thereof. (Embodiment 1) FIG. 1 is a sectional view of a drying apparatus according to Embodiment 1 of the present invention. That is, in the outer case 14 of the drying apparatus, the condensing part 4 for condensing the steam generated by heating is provided at an angle, and the vacuum insulating vessel 1 made of stainless steel is provided inside the condensing part 4. I have. A storage container 2 for holding a sample to be dried is detachably provided inside the vacuum insulated container 1, and an opening of the outer case 14 is connected to a door 3 that opens and closes when the sample is taken in and out of the storage container 2. ing. Further, a heat insulating material 8 is provided on a bottom surface inside the condensing unit 4, and a rotation driving unit 5 for rotating the storage container 2 is provided outside the bottom surface. Furthermore, door 3
A magnetron 6 serving as a heating means is mounted inside, a roller 9 for assisting the rotation of the storage container 2 is provided at an open end of the vacuum insulated container 1, and a condensed water is provided at a lower end of the condensing portion 4. A drain pipe 7 for discharging the water to the outside is provided through the outer case 14.

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

First, the door 3 of the drying apparatus is opened, and a sample such as food or garbage is put into the storage container 2. Next, the magnetron 6 is energized and the sample placed in the storage container 2 is heated by microwaves, and this heating is performed for a certain time. afterwards,
The rotation of the storage container 2 is started by the rotation drive unit 5 while heating by the microwaves is continued, and the sample placed in the storage container 2 is stirred. The water vapor generated from the sample by the microwave heating is discharged from the storage container 2 into the condensing part 4,
The water vapor is condensed into water by being cooled on the inner surface of the condensing section 4.
The condensed water passes through the drain pipe 7 and is discharged to the outside of the outer case 14.

In the above embodiment, an evaluation test was performed using garbage as a sample. By using the vacuum insulated container 1 having excellent heat insulation properties, the entire garbage can be dried uniformly and the sample can be efficiently heated. At the beginning of heating, the sample becomes sticky due to moisture such as boiling water, and when the rotation of the storage container 2 is started at that time, the boiled liquid adheres to the container. And it dries and stains the container. Therefore, after the sample is heated to reduce the volume to some extent, the storage container 2 is rotated to reduce the amount of stain. In addition, the heat insulating effect of the vacuum heat insulating container 1 is such that the temperature of the sample is uniformly increased during heating for a certain period of time, and in particular, the surface of the sample near the side wall of the storage container 2 dries, so that the upper part of the storage container 2 is hardly soiled. Further increase.
Also, by rotating the storage container 2 while tilting,
Since the sample in the storage container 2 is frequently stirred and the sample is removed in the range where the sample is moving around, the adhesion of the sample to the inner surface of the container can be minimized. Especially in the latter half of drying, when each sample moves frequently, the peeling effect becomes large.Therefore, restricting the movement of the sample in the early stage of drying when the contact area with the container is large, and restricting the adhesion of dirt are the consequences of contamination of the container. It greatly contributes to prevention. The inclination angle at this time can be arbitrarily selected from 40 to 90 degrees with respect to the vertical direction, and the larger the angle, the greater the stirring effect. Due to this effect, it is possible to perform the drying process with almost no contamination on the storage container 2. Although the storage container 2 does not have heat insulation in the present embodiment, the same effect as when the heat insulation portion is provided outside the storage container 2 can be obtained by using the storage container itself or one having heat insulation. Second Embodiment FIG. 2 is a sectional view of a drying apparatus according to a second embodiment of the present invention. Since the same components as those in the first embodiment are denoted by the same reference numerals, detailed description of those portions will be omitted. Example 1
A difference is in that using a heater instead of the magnetron 6 as an example of the heating means, the heater was placed in the door 3 inside, feeding as an example of a steam mixing means <br/> wind 11 And a bottom heater 12 disposed outside the bottom of the storage container 2 . Another difference is that the temperature detection unit 13 is disposed at the inner end of the door 3 .

[0012] The drying apparatus configured as described above,
The operation is almost the same except that the heating method is different from that of the first embodiment. The difference is that after the sample is heated in advance by the upper heater 10 and the blower 11, the start of the rotation driving unit 5 is controlled based on the temperature detected by the temperature detector 13, and the heating by the bottom heater 12 is performed together with the control. It is to do.

In the drying apparatus according to the second embodiment, the starting point of the rotation drive unit 5 is controlled based on the temperature of the storage container 2 detected by the temperature detection unit 13, so that the volume reduction state of the sample can be easily grasped. In addition, a constant effect of preventing the storage container 2 from being stained is obtained regardless of the type of the sample to be dried. In addition, water such as broth generated in the early stage of processing is stored in the lower portion of the storage container 2,
Furthermore, although heat from the upper part does not easily reach the lower part, the provision of a heating source at the lower part of the storage container 2 enabled quick drying. Further, the difference between the heating sources of the microwave heating and the heater heating does not significantly affect the effect of preventing the storage container 2 from being stained, and the same effect as in the first embodiment is obtained. Further, by applying a coating such as a fluororesin on the inside of the storage container 2, the slip of the sample on the inner surface of the storage container 2 is improved,
The effect of preventing the sample from adhering to the storage container 2 can be increased.

As described above, by heating the sample from the upper part for a certain time or until the temperature reaches a predetermined temperature, the moisture inside the sample moves from the upper part to the lower part of the sample, and the volume is reduced by the heating effect. After the heating period, by rotating and heating the storage container 2, the volume of the sample is reduced and the broth from the sample moves to the lower part of the container. Adhesion can be prevented. Also,
In the latter half of drying, the sample moves frequently while removing dirt adhering to the storage container 2 due to the tilt rotation, so that the dirt in the storage container 2 is minimized, and the sample is evenly distributed by the stirring effect by the tilt rotation. Heat. Further, the dirt attached to the storage container 2 may be excessively heated, particularly in heating the heater. That is, preventing the adhesion eliminates the thermal decomposition of the organic component caused by the excessive heating of the adhered dirt, improves the dried state of the sample, and can prevent the dirt attached to the entire apparatus.

In the above-described embodiment, an example in which garbage is dried is described. However, the present invention is not limited to this. For example, the present invention can be applied to the drying of the whole food or cooking.

Further, in the above embodiment, the magnetron 6 or the heater is used as the heating means. However, the heating means is not limited to this. For example, a halogen lamp, a ceramic heater or the like may be used as long as it can be a heating source. Any combination may be used.

In the above-described embodiment, the rotary drive unit 5 is provided outside the bottom of the condenser unit 4. However, the present invention is not limited to this. Alternatively, another rotation driving method may be used.

Further, in the above embodiment, the rotational drive is used as the movement by the drive means. However, the present invention is not limited to this, and if the sample is agitated, other drive methods using, for example, vibration may be used. Good.

[0019]

As is apparent from the above description, the present invention has the advantages that uniform drying and prevention of decay can be performed, and the contamination of the apparatus can be reduced.
