Description

The present invention relates to a coin cleaning and sterilizing apparatus, a cleaning and sterilizing method, and a cleaning and sterilizing medium used therefor. Such a cleaning sterilization apparatus, a cleaning sterilization method, and a cleaning sterilization medium can be sufficiently applied to general coin storage cases or coin storage apparatuses.

In the conventional coin cleaning apparatus and cleaning method, the cleaning agent is mainly liquid, and it is necessary to give a strict liquid seal structure and sealing operation to the apparatus and process. There was a burden. In addition, the coins immediately after separation from the cleaning liquid were wet, and the use of the wet coins was uncomfortable. In order to remove the wetting, a coin drying process and a drying time were further required. In addition, coin sterilization is mainly based on chemical action of chemical cleaning and sterilization, and physical rub action and adsorption action are not combined with this, and this does not lead to high cleaning efficiency. There was a problem that a relatively large amount of medicine and a long time were required for coin washing and sterilization.
