The present invention relates to a containing system, wherein work to load and unload a substance inside a containing unit can be more convenient and easy, and a receptive substance is discharged to achieve pneumatic equilibrium between the inside and the outside of the containing unit when pneumatic pressure inside the containing unit is reduced, thereby preventing the containing unit from being contracted to prevent damage to the containing unit. According to an embodiment of the present invention, the containing system comprises: a first frame structure; a plurality of first discharge units placed in the first frame structure; a second frame structure coupled to the first frame structure; a first containing unit fixedly supported by the second frame structure; a second containing unit connected to the first containing unit; a second discharge unit connected to the second containing unit; and a pressure control unit connected to the first containing unit. |
