1. An aerosol generating apparatus, comprising:
a supercritical extraction unit that includes at least one of tobacco and aromatic plant as a raw material, and is configured to extract an extraction component from the raw material by a supercritical fluid;
a collection unit configured to collect the extraction component discharged from the supercritical extraction unit as a collection material;
an inlet part that is disposed between the supercritical extraction unit and the collection unit and serves as a path through which the extraction component is introduced from the supercritical extraction unit into the collection unit;
a heating unit comprising:
a first heating unit configured to heat the supercritical extraction unit based on the extraction component being extracted from the raw material, and
a second heating unit configured to heat the collection unit to generate aerosol; and
a body part in which the supercritical extraction unit, the collection unit, the inlet part, and the heating unit are disposed,
wherein the body part includes a groove formed at one end and configured to discharge the aerosol therethrough,
wherein the supercritical extraction unit, the collection unit, and the inlet part are separable from the body part and are replaceable, and
wherein the inlet part includes a gate configured to open and close in response to a supply of the supercritical fluid.
