The present invention relates to a hot compression device using a microwave, and in particular, to irradiate the compression plate made of a material having a property of microwave transmission to the microwave generated in the microwave generator, the compression plate and the metallic reflector The compressed material injected therebetween is irradiated and dried at the same time using the heat of the compression plate and the reflector plate heated by the molecular vibration friction action and the medium reaction of the transmitted and reflected microwaves, and the pressure is applied through the compression plate and the reflector plate. The present invention relates to a hot compression device using microwaves for press forming, drying or compressing a compressed object.

     Compression apparatus that pressurizes the compressed object inserted between the compression plates through the compression plate to press-mold the compressed object or compress the coating or the object, is applied to the cold compressor and the compression plate that pressurize directly without applying heat to the compression plate. It can be roughly classified as a hot compressor which is pressurized by applying heat. This is divided into mechanical type which presses by screw etc. by the driving method of compression plate and pneumatic cylinder type and hydraulic cylinder type which press by using air pressure or hydraulic pressure, etc. It is divided into a single layer and a multi-layer that presses a plurality of compressed materials at once, and the single system type and the compression plate are separated into a plurality of systems and the single compression type plate is operated as a single system by separate operation of the compression plate. It is divided into divided system type, and various kinds of compressors, such as three-way and multi-directional compressors, such as one direction such as upward and downward and up and down, and up and down sides, are developed and distributed according to the compression direction.

     Cold compressors, which have been the mainstream in the past, are being replaced by hot compressors due to the improvement of production efficiency, the promotion of reactions of additives such as adhesives added to the compressed products, and the improvement of the quality of the compressed products. In the hot compressor, a method of heating a compression plate with a heating plate heated by electrical resistance by a heating method and a method of heating a compression plate by passing heated thermal conductive oil, hot water, steam, and the like through a perforation part of the compression plate, are introduced. In the former case, due to cost and practicality, it is not widely used, and a hot compressor using the latter method is widely used and widely used. However, the hot compressor requires a separate boiler and piping for heating the heat medium or steam, which is a heating medium, and it is difficult to smoothly adjust or change the heating temperature or conditions, and a temperature difference occurs between the inlet and the outlet of the heating medium and the pipe spacing. It is difficult to equalize the temperature of the compression plate, the thermal efficiency is low, the time required for compression heating is long, and because of the heating method in which heat is conducted from the outer surface of the compressed object to the inside, curing, reaction, It is easy to show the difference in degree in moisture content and the like, and there is a problem in that quality uniformity and deformation prevention of the compressed object are difficult.

In order to improve the problems of the conventional hot compressors, hot compressors using ultrasonic waves and high frequencies have been introduced. However, ultrasonic compressors are used for limited applications such as crimping of small areas or small plastics, and are rarely applied as full-scale compressors. In the case of the high-frequency compressor, there is an advantage that can solve most of the problems of the conventional hot compressors as described above has been variously utilized and developed in recent years, such as wood composite bonding, coating bonding, molding. However, in case of the high frequency hot compressor, a separate high frequency generator is required on the outside, and it is composed of the structure that heats the object by generating high frequency and puts the compressed object between the pole plates of the compression plate which is mainly composed of metallic conductor. Since the insulation device is an essential component on the rear surface of the plate pole plate, it is difficult to make a multi-layer compressor that heat-presses a large number of objects at once, and mainly produces and uses a single-layer hot compressor that heats and presses only one object at a time. It is true. In addition, although many efficiency improvements have been made over the conventional heating method, there is still a problem in that heating time and additional power consumption are further reduced.

On the other hand, by using a blowing agent such as volatile decomposable water solubility to the workpiece made of organic raw materials such as resins, inorganic raw materials such as mineral powders, and the like, by mechanically stirring them and heat-expanding the raw materials to form a foam body In the foaming machine or foam molding machine that manufactures products foamed to the specific gravity that requires raw materials by the method, hot water steam heat conduction oil hot air is used as the heat source used for foaming, and it is effective for compression molding of large products or thick products. Preheating is performed by heat source such as high frequency to improve the quality and quality, but it is necessary to pre-exposure according to the product and process, or to perforate the mold to penetrate the heat source such as saturated steam, or due to the influence of residual moisture and air. Appearance quality of product due to temperature difference and melt decomposition between skin and core There is a problem, such as the troubles on the production yield and reduction in the occurrence, a situation that the heat efficiency is high and productivity is expected heat source is water-permeability and good drying capabilities.

In addition, in the dryers mainly used for wood and agricultural products, in addition to the steam dryers and hot air dryers that are commonly used, vacuum dryers and high-frequency heating dryers, high-frequency vacuum dryers, and microwave dryers using the principle of lowering the boiling point of water in a vacuum state are introduced. . The high-frequency vacuum dryer, which has been evaluated as having greatly improved the drying speed while reducing problems such as cracking and deformation shrinkage and color change after drying, has a large temperature difference between the positive electrode plate and the negative electrode plate, and has a large amount of residual condensate on the surface of the product on the two electrode plates. It is mainly used for specific purposes such as preliminary drying of large timber, difficult to dry wood or expensive wood and agricultural products due to problems such as increase in surface function ratio and high cost of electricity consumption and equipment price compared to other methods. There is a situation. In the case of microwave dryers, mainly tunnel type or small chamber type dryers are introduced to improve the problems of high frequency dryers, but in the case of thick materials, the moisture content varies depending on the parts. After or through the third drying process is required, in the case of thin materials there is a problem that there is a risk of deformation due to high-speed drying.

The present invention has been devised to solve the problems of the existing hot compressor, there is no need for a separate boiler and the drilling work for drilling of pipes or compression plates on the outside, it is easy to smoothly control or change the heating temperature or conditions In addition, it is possible to homogenize the temperature of the compression plate, improve the thermal efficiency, reduce the time required for compression heating, and also to maintain the quality uniformity and the deformation prevention of the compressed object by the heat being conducted simultaneously from the outer surface and the inside of the object to be heated and dried. It is an object to provide a compressor. In addition, by improving the overall problems of the high-frequency hot compressor, there is no need to install a separate equipment in the outside to place the heat source generator inside the compressor to increase the space utilization, the structure easy to manufacture a multi-layer compressor for heating and pressing a plurality of objects at once To increase production efficiency, and the strong permeability and heat generation of microwaves with a frequency of 300-300,000 MHz, which is usually hundreds of times higher than that of 6.78 MHz or more commonly used 13.56 MHz or 27.12 MHz It is another object of the present invention to provide a hot compressor that can further reduce the time required for compression heating by further improving the heating efficiency by using the composition and reflectivity, which can reduce the required power consumption and can be inexpensive to manufacture.
