Abstract: An odor blender is provided in which a number of component odor gases may be increased without increasing the number of carrier gas containers while ensuring a single odor gas concentration is not reduced. The odor blender includes N odor containers, M less than N) carrier gas containers, a blend line leading to a blend part for blending the odor gases, a bypass line for discharging odor gases, and solenoid valves for switching the containers between the blend line and the bypass line. A computer sets the number of odor containers connected to the blend line at the same time to M or less, connects the same number of carrier gas containers to the bypass line as the number of odor containers connected to the blend line, and controls timing of connection of odor containers to the blend line based on a predetermined mixing ratio of the component odor gases.

Abstract: An odor blender is provided in which a maximum gas concentration of a single component odor gas is not reduced without increasing the number of carrier gas containers, even when the number of the types of component odor gas is increased. An odor blender includes N (an integer of 2 or more) component odor containers 102-1032, M (an integer of 1 or more and less than N) carrier gas containers 101, a blend line 12 for leading component odor gases to a blend part, the bypass line 13 for discharging the component odor gases, the blend part 14 for blending the component odor gases, and solenoid valves 11 for switching a connection from the component odor containers and the carrier gas containers to between the blend line and the bypass line.
