摘要:
Disclosed are an extractor having a “pottery with dark brown glaze” called “Onggi” in Korean, and a method of extracting using the same. The extractor includes a body, a body cover, a heating part, a pottery and a gas valve. The pottery is located within the body. The extractor extracts by injecting nitrogen gas, etc. into the body through a gas valve, thereby rendering the inside of the body to be high pressure state during extraction. Thus, the inside of the body is maintained under high pressure during extraction. Accordingly, an extract is located only within the pottery, and thus changes that can be caused while an extract contacts with the body can be prevented.
