PROBLEM TO BE SOLVED: To solve the problems that, in a device for purifying an article by using an agent or harmful gas, the agent or the harmful gas may leak into a work space out of the device, and that, especially in the case of an article used for food, it is required to remove a remaining agent, to thereby impose a heavy burden on management or a facility.SOLUTION: An agent or harmful gas is not used for purifying an article but charged particles obtained by discharging in the atmosphere are used. Further, desorption of an attachment from the article is facilitated by using an air current having strength fluctuation in order to send out the charged particles.SELECTED DRAWING: Figure 1 |
