Abstract
Description
本發明係有一種連續式微波加熱系統，更特別是有關於一種可以安全使用且快速升降溫的連續式微波加熱系統。 The present invention relates to a continuous microwave heating system, and more particularly, to a continuous microwave heating system that can be used safely and rapidly raises and lowers the temperature.
傳統加熱方式，例如火焰、熱風、電熱、蒸汽等，都是利用熱傳導的原理將熱量從被加熱物外部傳入內部，逐步使物體中心溫度升高。要使物質中心部位達到所需的溫度，需要一定的時間，導熱性較差的物體所需的時間就更長。 Traditional heating methods, such as flame, hot air, electric heat, steam, etc., all use the principle of heat conduction to transfer heat from the outside to the inside of the object to be heated, gradually increasing the center temperature of the object. It takes a certain amount of time for the center of a substance to reach the required temperature, and objects with poor thermal conductivity take longer.
微波是頻率在300MHz到300GHz的電磁波，通常是作為資訊傳遞而用於雷達、通訊技術中。近年來也應用在各種工農業上，用於加熱、乾燥或裂解物質。常用的微波功率頻率是915MHz和2450MHz，可以使極性物質分子之間互相摩擦產生熱量及發熱。使用中，可根據加熱材料的形狀、大小、含水量來選擇。微波加熱是使被加熱物本身成為發熱體，不需要熱傳導的過程，內外同時加熱，因此能在短時間內達到加熱效果。且微波加熱時，物體各部位通常都能均勻滲透電磁波，產生熱量，因此均勻性大大改善。在微波加熱中，微波能只能被加熱物體吸收而生熱，加熱室內的空氣與相應的容器都不會發熱，所以熱效率極高，生產環境也明顯改善。 Microwaves are electromagnetic waves with frequencies between 300MHz and 300GHz. They are usually used in radar and communication technology for information transmission. In recent years, it has also been used in various industrial and agricultural applications for heating, drying or cracking materials. Commonly used microwave power frequencies are 915MHz and 2450MHz, which can cause polar material molecules to rub against each other to generate heat. During use, you can choose according to the shape, size and moisture content of the heating material. Microwave heating is a process in which the object to be heated becomes a heating element without the need for heat conduction. The inside and outside are heated at the same time, so the heating effect can be achieved in a short time. And when microwave heating occurs, electromagnetic waves can usually penetrate all parts of the object evenly and generate heat, so the uniformity is greatly improved. In microwave heating, microwave energy can only be absorbed by the heated object to generate heat. Neither the air in the heating room nor the corresponding container will generate heat, so the thermal efficiency is extremely high and the production environment is significantly improved.
在過去的微波加熱設備中，並不是所有的物料能有效地吸收微波，另一方面，物料被加熱到高溫後，要取出通常要一段時間。 In the past microwave heating equipment, not all materials can effectively absorb microwaves. On the other hand, after the materials are heated to high temperatures, it usually takes a while to be taken out.

微波對不同性質的物料有不同的作用，對乾燥作業有利。因為水分子對微波的吸收最好，所以含水量高的部位，吸收微波功率多於含水量較低的部位這就是選擇加熱的特點。烘乾木材、紙張等產品時，利用這 一特點可以做到均勻加熱和均勻乾燥。值得注意的是有些物質當溫度愈高、吸收性愈好，造成惡性循環，出現局部溫度急劇上升造成過乾，甚至炭化，對這類物質進行微波加熱時，要注意制定合理的加熱製程。 Microwaves have different effects on materials of different properties, which is beneficial to drying operations. Because water molecules absorb microwaves best, parts with high water content absorb more microwave power than parts with lower water content. This is the characteristic of selective heating. Use this when drying wood, paper and other products One feature enables uniform heating and uniform drying. It is worth noting that the higher the temperature, the better the absorptive properties of some substances will be, resulting in a vicious cycle, with local temperatures rising sharply, causing overdrying or even carbonization. When microwave heating such substances, attention should be paid to formulating a reasonable heating process.

The microwave power sources 120 provide microwave energy 122 into the heating cavity 110, and the microwave frequency of the microwave power sources 120 is selected from one of 950 MHz, 2450 MHz or 5800 MHz. Since the heating cavity 110 has the inlet opening 112a and the outlet opening 112b, the heating cavity 110 needs to connect the first microwave suppression cavity 130a and the second microwave suppression cavity 130b to prevent microwave energy from passing through the cavity.
