におく＠処理がとられている。Prior Art: In the decomposition or processing and utilization of various plant resources, it is common practice to perform pretreatment to a state where each of their components can easily undergo the necessary treatments. For example, in the saccharification treatment of sawdust, which is wood processing waste, it is hydrolyzed using acids or enzymes as a catalyst, converting cellulose as a plant component into glucose, hemicellulose into glucose, xylose, and other sugars, and separating and decomposing lignin. However, in order to carry out the treatment efficiently in this case, a @ treatment is used in which the material is subjected to high temperature and high pressure in advance.

同時に加圧はできなかった。Conventionally, this heat treatment of plant components has been carried out in a batch method in which sawdust is stored in a hydrated state in a vessel made of gold quartz, hard glass, etc. to form an S electric body, and heat is generated in a high frequency electric field using microwaves. This method is reasonable and effective for heat treatment of plant ingredients, but vessels made of quartz or other materials are brittle and not strong enough for such operations, so high temperature and high pressure treatment is necessary. The disadvantages of using microwaves are that they cannot be used with microwaves, that it is necessary to use a discontinuous patch method, and that a slow cooling process is required. In addition, continuous [white] methods involve drying wood and heating plant ingredients in granular form using a belt conveyor method, but this process is performed at atmospheric pressure F, and is simply heated and pressurized at the same time. I couldn't.

等の便益が得られ産業−ヒの利用性は高いのである０As seen in the conventional example, if you want to obtain high temperature and high pressure in steam, it is necessary to install a high temperature and high pressure boiler, and when heating means using electric heat or direct flame, the temperature of the outer surface of the tube increases, and the temperature inside the tube increases.

(a) high-temperature heat treatment at 100 to 160°C, and (b) processing of raw materials such as wood and hoods at 150 to 270'C. In contrast, benefits such as lowering the molecular weight of lignin and hemicellulose, and (iii) increasing the organic reaction rate under high pressure of inert gases such as nitrogen are obtained, making it highly usable in industry.
