The object to be dried, the object to be concentrated,
A mechanism for rotating a jig that holds a material to be thawed, a material to be roasted, and a material to be sterilized is not suitable for mass production because the device becomes expensive and the mounting amount is limited. Also, in the method of moving the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized, the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are often used. In addition to the above, there is a problem that scattered objects may be generated, and the apparatus is complicated and expensive, and maintenance such as cleaning becomes complicated, which is not preferable.

In a continuous production system in which a material to be dried, a material to be concentrated, a material to be thawed, a material to be roasted, and a material to be sterilized are transferred on a conveyor, continuous productivity is excellent, but drying, concentration, thawing, Roasting and sterilization control management is difficult. That is, since it is a continuous feeding, it is always not dried, not concentrated, not thawed, not roasted,
Unsterilized material to be dried, to-be-concentrated, to-be-thawed, roasted, to-be-sterilized and dried, concentrated, thawed, roasted, to-be-dried, to-be-concentrated, to-be-thawed, Since the roasted material and the material to be sterilized are mixed, it is difficult to detect drying, concentration, thawing, roasting, and sterilization, and it cannot be said that the production efficiency is high. In addition, when the dried material, the concentrated material, the material to be thawed, the material to be roasted, and the material to be sterilized having different moisture contents at each time of the charging, each material to be dried, the material to be concentrated, and the material to be thawed are added. , Drying, concentration, thawing,
Roasting and sterilization control management is extremely complicated. In addition, the drying, concentration, thawing, roasting, and sterilization accuracy are low in spite of the increase in the size of the apparatus, so that much time and cost are required to obtain a good product. For the above reasons, the drying, concentration, thawing, roasting, and sterilizing apparatuses that simultaneously use microwaves and far infrared rays under reduced pressure have not been widely used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to control the pressure of a decompression tank to one or more target decompression degrees, and to dry, condense, To-be-defrosted, to-be-roasted, to-be-sterilized, to-be-dried, to-be-concentrated, to-be-defrosted to perform controlled microwave heating and controlled far-infrared heating simultaneously or partially or entirely in all steps. In the method for drying a material to be roasted and a material to be sterilized, operations such as stirring, rotation and movement are performed on the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized in a decompression tank. An object of the present invention is to provide a method and an apparatus for efficiently drying, concentrating, thawing, roasting, and sterilizing an object to be dried, an object to be concentrated, an object to be thawed, an object to be roasted, and an object to be sterilized at a fixed position. .

That is, the present invention provides a method for drying a substance to be dried,
Drying, concentration, thawing, roasting, and sterilizing jigs such as plates and trays that hold the objects to be thawed, objects to be roasted, and objects to be sterilized, and the shelf-type jigs that support them at fixed positions in the vacuum tank. Accordingly, it is an object of the present invention to solve the problem of low production throughput due to a rotary jig or the like. If the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, the material to be sterilized, and the jig are allowed to stand for drying, concentration, thawing, roasting, and sterilizing, plates and trays outside the vacuum tank Set a large amount of dried material, concentrated material, thawing material, roasted material, and sterilized material in jigs such as
In addition, it becomes possible to mount a large amount of such jigs such as plates and trays on a shelf-type jig, etc. Large quantities of materials, concentrates, thawing materials, roasting materials, and sterilizing materials can be easily supplied.

[0008] The material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are allowed to stand without being stirred, and then dried, concentrated, thawed, roasted, and sterilized. An object of the present invention is to prevent a dried substance, a substance to be concentrated, a substance to be thawed, a substance to be roasted, and a substance to be sterilized from scattering into a tank. However, movement such as rotation and agitation can be performed on dried objects, concentrated objects, thawed objects, roasted objects,
It is considered difficult to obtain uniformity of microwave heating and far-infrared heating because it is not applied to the object to be sterilized, but this point is solved by arbitrarily combining the means of claims 3 to 10. can do.

[0009] In addition, the conventional means for continuously supplying, moving, and feeding the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized on the belt conveyor has a good continuous productivity. However, it is difficult to perform sufficient drying, concentration, thawing, roasting, and sterilization control. That is, sequentially, the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are not continuously produced unless they are put into the tank and taken out sequentially, and therefore, immediately after being put into the tank. Untreated material to be dried, material to be concentrated, material to be thawed, material to be roasted, material to be sterilized, drying, concentration, thawing, roasting, material to be dried, material to be concentrated, material to be thawed, Since the roasted material and the material to be sterilized are always present, the change in the degree of decompression becomes irregular because the balance between the amount of generated steam and the exhaust amount of the vacuum pump does not change regularly, so that the degree of decompression change and It is not possible to perform highly accurate drying, concentration, thawing, roasting, and sterilization control by recognizing the amount of change in the degree of reduced pressure. The present invention solves the problem of this point by drying, concentrating, thawing, roasting, sterilizing a large amount of a substance to be dried, a substance to be concentrated, a substance to be thawed, a substance to be roasted, and a substance to be sterilized in a batch manner. By going
Since only dried, concentrated, defrosted, roasted, and sterilized materials having approximately the same level of dryness are present in the decompression tank, the change in the degree of decompression and the amount of change in decompression are fixed. Thus, it is possible to obtain high-precision control by recognizing information.

[0020]

According to the first and second aspects of the present invention, a jig such as a plate or a tray for rotating and stirring the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized, By placing the jigs supporting them at a fixed position without giving a rotation, the space loss is small due to the absence of the rotating shaft and the fact that the jigs can be mounted squarely, and the mounting area and volume can be significantly increased. In addition, mass productivity can be pursued from the simplicity of carrying the jig into the tank using a lifter or the like.
Also, on a conveyor or the like, the material to be dried, the material to be concentrated, the material to be thawed,
It is possible to pursue high-precision drying, concentration, thawing, roasting, and sterilization by placing the material to be roasted and the material to be sterilized in a fixed position without moving, drying, concentrating, thawing, roasting, and sterilizing. .

Because, in order to control drying, concentration, thawing, roasting, and sterilization with high accuracy, it is necessary to capture a change in the degree of decompression based on the balance between the amount of evaporation of water and the displacement of the vacuum pump. However, in the continuous feeding system, the unprocessed material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are sequentially charged, so that the material is dried, concentrated, thawed, roasted, and sterilized. It is difficult to catch the change in the decompression degree for control because the undecomposed thing and the thing just before drying, concentration, thawing, roasting, and sterilization are mixed and the change in the constant degree of the decompression degree is not realized. However, according to the method, only the same degree of dryness, concentration, thawing, roasting, and sterilization are to be dried, concentrated, thawed, roasted, and only sterilized. Since it will be present in the decompression tank, the amount of generated steam and Law recognition becomes possible, for the first time highly accurate dryness, enrichment, decompression degree, degree of roast, it is possible to sterilize degree detection.

According to the third aspect of the present invention, the uppermost and lowermost reflectors of the shelf-type jig are provided with the objects to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, the material to be sterilized, and the like at the uppermost stage and the lowermost stage. The material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized in the stage can be subjected to microwave heating and far-infrared heating with almost the same power. The set distance of the reflector from the jig such as a plate or a tray and whether the reflector is partially reflected or totally reflected is adjusted by a microwave input position, a far-infrared reflection position, and the like.

According to the fourth and fifth aspects of the present invention, the area where the microwaves are heated can be averaged by the side surfaces of the shelf-shaped jigs and the reflectors horizontally provided on each step. Without the reflector, microwaves and far-infrared rays start heating from the nearest position, but with the reflector,
Since heating to a distant position is performed at the same time, uniform heating is provided.
The position, the number, and the area of the reflectors are adjusted according to the microwave input position and the far-infrared radiation position.

A reflection frame is set on each of the jigs, such as plates and trays, for holding the object to be dried, the object to be concentrated, the object to be thawed, the object to be roasted, and the object to be sterilized. In the jigs such as plates and trays,
As described in claim 4, the microwave and the far-infrared ray heat the peripheral portion and the central portion at the same time, so that they are provided for uniform heating. The size of the reflection frame is adjusted according to the size of the plate and the type of the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized.

According to the seventh aspect, when the shelf-type jig is made of metal such as stainless steel, if the tip of the jig and the inner wall of the decompression tank are too close to or in contact with each other, a discharge may occur due to microwaves. In order to prevent this, a block made of a heat-resistant and microwave-permeable body such as a fluororesin is provided between the tip of the jig and the inner wall of the decompression tank. Generally, discharge can be prevented if the thickness is 10 mm or more, but the thickness is selected depending on the apparatus.

According to the eighth aspect of the present invention, more uniform heating can be achieved by modifying the jigs such as plates and trays for holding the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized. It is designed to be able to do it, and it has a structure in which the central part which is the last heating part by microwave is raised, and the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted,
The loading amount of the object to be sterilized is reduced so that the surrounding area is heated simultaneously. The area and height of the raised portion are adjusted according to the type of the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized.

In the ninth aspect, when the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are scattered in the tank due to bumping or the like, the material to be dried, the material to be concentrated, Covering the upper part of the jigs such as plates and trays holding the objects to be thawed, roasted and sterilized with paper material prevents scattering and ensures highly accurate control and cleanliness inside the tank. At the same time, although the paper material is not high in efficiency, it has a performance of transmitting microwaves, so that it is also used for uniform heating of microwaves.

According to claim 10, a solid to be dried is provided.
When the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are cut flat and loaded, microwave heating can be performed directly on the cut surface when the cut surfaces are completely overlapped. No drying, concentration, thawing, roasting and sterilization are difficult. Therefore, cutting is performed in a waveform, and when loading, the material to be dried, the material to be concentrated, the material to be thawed, the material to be roasted, and the material to be sterilized are mounted so that a space by the waveform cutting is created on the mounting surface where the material to be dried overlaps. Then, the microwave heating is performed evenly and uniformly on the cut surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 As an embodiment according to claims 1 to 7, in a decompression tank using a 5 kW output microwave oscillator, a 4 kW far infrared heater and a 5 kW vacuum pump, a stationary type is used. Using a shelf-shaped jig, and attaching a 20 mm thick Teflon, which is a heat-resistant and microwave-permeable body, to the part of the leg of the shelf-shaped jig that is in contact with the tank at the tip, and discharge the microwave. Was set so that it did not become a factor.
The size of the shelf-type jig is 45cm square on a plane, and the height is 1m
And the number of shelves was seven. First, a water temperature rise test was performed using a beaker without attaching a reflector to the shelf-type jig at all. One beaker containing 80 cc of water was mounted at each of the four corners and the center of each tray, and a total of 35 beakers used 2,800 cc of water. In the test, the initial water temperature was 20 ° C, and 5kW microwave and P
Heating was performed for 2 minutes by a far-infrared heater whose output was controlled by ID, and the temperature distribution of the water temperature in each beaker was repeatedly measured three times to obtain an average value of the water temperature of each beaker. As a result, the water temperature rise was the fastest at 82 ° C. on the lowermost microwave inlet side and 81 ° C. on the uppermost microwave inlet side. Conversely, the central stage ( The temperature was 52 ° C. at the center of (4th stage). Since there was a difference of about 30 ° C., it was confirmed that considerable uneven heating was performed.

Next, as an embodiment of the present invention, the upper part of the uppermost tray of the shelf type jig for holding the tray is 10 mm from the upper part.
100mm from the position above 0mm and the lower part of the bottom tray
The same test was performed by attaching a stainless steel reflector to the entire surface of the flat surface at the position shown in FIG. As a result, the water temperature rise was the fastest at 73 ° C. on the lowermost microwave input side and 71 ° C. on the uppermost microwave input side, and conversely, the water temperature rise was the slowest at the center stage ( The temperature was 63 ° C. at the center of the fourth stage. Although a significant improvement was observed, a difference of about 10 ° C. was still observed.

Next, according to an embodiment of the present invention, a stainless steel rectangular reflector is provided on the side surface of a shelf-shaped jig close to a beaker having a higher water temperature, and the reflector and the shelf-shaped jig are provided with microwaves. The same test was performed while measuring the temperature distribution while maintaining the interval so as not to induce discharge. As a result, the water temperature rise was the fastest at 66 ° C. on the microwave inlet side of the second stage from the top and 65 ° C. on the microwave inlet side of the second stage from the bottom. Conversely, the water temperature was the slowest. Was 60 ° C. at the center of the middle stage (fourth stage). Uniform heating up to a difference of about 5 ° C. was realized.

Next, in a fifth embodiment of the present invention, a stainless steel reflecting plate having a width of 30 mm from the outside is placed along the periphery of the shelf-type jig holding the tray at a plane position where the tray of each stage is placed. Attached. As a result, the water temperature rose most rapidly at the center of the second stage from the top at 64 ° C and at the center of the second stage from the bottom at 63 ° C. The slowest was 60 ° C. on the side of the fourth stage microwave inlet. As a result, 4
It was found that uniform heating up to a difference of about ° C was realized.

Next, as another embodiment of the present invention, a similar test was conducted by setting a reflection frame formed of a stainless steel angle having a width of 10 mm above each tray. As a result, the difference in water temperature between the beakers was within 2 ° C., and uniform heating at a high level was observed.

Next, the beaker was replaced with a towel containing water, and heating was advanced by operating a vacuum pump. However, according to the method of claim 7, no discharge was detected at the legs of the shelf-type jig. No discharge was detected even when the shelf-type jig was suspended as shown in the figure.

Example 2 The mechanism of claims 1 to 7 described in Example 1 was used, and as an example of claim 8, 7 kg of seasoning paste was used.
Was dried. First, using a flat tray on the bottom, the paste was mounted flat and dried, but when it was taken out for the first time, the center part was somewhat dry, so when it was dried again, the center part was dried, Burning occurred in a part of the outer periphery. Next, as shown in the claims, a tray in the form of a dome was used in which the bottom of the central portion of the tray was raised to a dome shape so that the bottom of the tray had a diameter of 80 mm and the height of the center was 7 mm. . In this case, the whole paste was uniformly dried, and good results were obtained. This is an extremely effective means when a paste or the like is automatically loaded on a tray by a mechanical device.

Embodiment 3 The mechanism of Claims 1 to 8 described in Embodiments 1 and 2 is used, and as an embodiment of Claim 9, yolk 3.5 is used.
kg was dried. First, the upper part of the tray was dried in the open state as it was, but the yolk swelled and the yolk flowed out of the tray, so that good drying could not be performed. Next, an upper portion of the tray was covered with siliconized paper, which was fixed with the reflection frame according to claim 6 and dried. The yolk could be prevented from flowing out of the tray, and the dried yolk adhering to the siliconized paper could be easily removed, and good drying results were obtained.

Fourth Embodiment A mechanism according to the first to eighth embodiments described in the first and second embodiments is used.

And dried. As a result, it took time to dry the portion where the cut surfaces were overlapped, and the portion was burnt. Next, similarly, it was cut into a waveform with a thickness of about 5 mm, and was loaded with a thickness of about 30 mm so that a space was formed between the cut surfaces, and dried. The drying time was short and good drying results were obtained.

Example 5 As an example of concentration, 7 kg of strawberry was concentrated using the mechanism of claims 1 to 8 described in Example 1 and Example 2. This strawberry is obtained by removing the fly before being put into the apparatus and sterilizing the strawberry by immersing it in ethanol as it is. Concentration was started by loading 2 kg each on 7 plates. The microwave output was set to 5 kW, the far infrared output was set to 4 kW, and the concentration was set at about 40 torr in the central pressure reduction range. During the concentration step, the internal temperature of the strawberry was measured by a three-point fiber thermometer.
± 2 ° C. This coincides with the boiling point of water at 40 torr of about 34 ° C., which indicates that the heating temperature is controlled by the degree of pressure reduction and that uniform heating is being performed. After 40 minutes, the operation was stopped and strawberries were taken out and weighed.
It was 600 g. That is, about 70% of the total moisture 4
This means that 400 g of water was removed. When this is crushed to sanitary, it is clean and has very little oxidation.
A strawberry paste excellent in taste, aroma and color was obtained.

Example 6 As an example of thawing, 14 kg of frozen sliced carrot was thawed by using the mechanism of claims 1 to 8 described in Example 1 and Example 2. When 7 kg of each plate were loaded with 2 kg each, the energy was set under the same conditions as in Example 5, and thawing was performed. As a result, uniform thawing with very little dripping could be performed as a whole. The thawing time was 18 minutes. The thawed carrot was excellent in color, aroma and taste.

Embodiment 7 As a roasting embodiment, burning of crude tea was carried out using the mechanism according to claims 1 to 8 described in Embodiments 1 and 2. Seven plates were loaded with 1 kg of crude tea, and the microwave output was set to 1 kW. Stop heating after 25 minutes,
The heating temperature was measured with thermo labels installed at three places on each plate.
