Abstract

A large capacity natural material composition conversion apparatus using a microwave with a preset pressure function includes a chamber including a sealed reaction space accommodating a material, an radiator configured to heat the material by radiating a 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, and preliminarily increase a pressure of the reaction space by controlling the pressure regulator before heating the material.

First claim

What is claimed is:

1. 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.

2. The natural material composition conversion apparatus of claim 1 , further comprising an agitator arranged in the reaction space and configured to agitate the material.

3. The natural material composition conversion apparatus of claim 1 , further comprising an auxiliary heater surrounding at least a part of the reaction space and configured to auxiliarily heat the material by transferring heat toward the reaction space.

4. The natural material composition conversion apparatus of claim 3 , wherein the auxiliary heater surrounds at least a part of an outer surface of the chamber, is configured to generate heat being operated by an external electrical signal, and is separable from the chamber.

5. The natural material composition conversion apparatus of claim 3 , wherein the chamber further comprises an internal mantle for forming at least a part of the reaction space, and
wherein the auxiliary heater is arranged inside the chamber to surround at least a part of an outer surface of the internal mantle, is configured to generate heat being operated by an external electrical signal, and is separable from the internal mantle.

6. The natural material composition conversion apparatus of claim 1 , wherein the controller is further configured to control the radiator and the pressure regulator based on information on at least one of a heating temperature for heating the material in response to a kind of the material accommodated in the reaction space, the preliminary pressure condition to be formed in the reaction space, and a time for heating the material.

7. The natural material composition conversion apparatus of claim 1 , wherein the chamber comprises a plurality of division chambers that are coupled to one another to form the reaction space, and the plurality of division chambers are separable.

8. The natural material composition conversion apparatus of claim 7 , wherein the chamber is provided over a movable plate, and
wherein the movable plate is movably provided over a fixed plate.

9. The natural material composition conversion apparatus of claim 8 , wherein the plurality of division chambers include a first division chamber and a second division chamber,
wherein the first division chamber is provided above the second division chamber toward an upper portion of the chamber, and
wherein the second division chamber is fixedly provided on the movable plate to move above the fixed plate together with the movable plate.

10. The natural material composition conversion apparatus of claim 8 , wherein the movable plate is provided over the fixed plate to linearly move along a straight rail.

11. The natural material composition conversion apparatus of claim 1 , wherein the pressure regulator comprises a gas supply device for supplying any one of helium, argon, nitrogen, air, and oxygen, or a mixture thereof into the reaction space.
