Large capacity natural material composition conversion apparatus using microwave with preset pressure function

A natural material composition conversion apparatus using a microwave, the natural material composition conversion apparatus comprising:

• a chamber comprising a sealed reaction space configured to accommodate a material including a mixture of a solvent and a natural product;
• a radiator configured to heat the material by radiating the microwave into the reaction space;
• a pressure regulator configured to regulate a pressure of the reaction space by supplying a gas into the reaction space;
• and
• a controller configured to:
• control the pressure regulator and the radiator based on information on a boiling point of the material;
• control the pressure regulator to preliminarily increase the pressure of the reaction space based on information on a preliminary pressure condition to be formed in the reaction space in response to a type of the solvent to increase the boiling point of the material before heating the material;
• and
• control the radiator to heat the material when the preliminarily increased pressure of the reaction space reaches a target pressure.
