Abstract
This study was conducted to perform for comparative analysis of the cleaning efficiency on 3 kinds of cleaning liquid state, 3 steps of cleaning temperature $(45^{\circ}C,\;60^{\circ}C,\;70^{\circ}C,\;)$ and 6 steps of cleaning time (2.5, 5, 7.5, 10, 12.5, 15 minute). 3 kinds of cleaning liquid state are the non fluidized bed, liquid fluidized bed and liquid/solid fluidized bed. UV spectrophotometer was used in estimation of cleaning efficiency, which it is experimental equipment using the absorptiometric analysis method. Cleaning efficiency by cleaning time was increase from 2.5 minutes to 15 minutes, liquid/siolid fluidized bed was indicated the highest cleaning efficiency among the 3 kinds of cleaning liquid state and $70^{\circ}C$ of cleaning temperature at liquid/solid fluidized bed was indicated the highest cleaning efficiency as 98% among the 3 steps of cleaning temperature.
