<p><P>PROBLEM TO BE SOLVED: To provide a pipe washer capable of efficiently and economically washing the interior of production facilities of beverages, foods, pharmaceutical products, cosmetics, and the like. <P>SOLUTION: Time T for applying a rinse solution is determined for each pipe system 11 depending on pressure loss, the number of packings at a pipe connection part, Reynolds number, and the like. Specifically, the predetermined time T has passed following the application of the rinse solution, a valve 60 is closed, and thus a rinse step at the relevant pipe system 11 is completed. Accordingly, a rinse solution is supplied for a long time period in a pipe system 11 where the rinse solution flows with difficulty so as to take much time for the rinse step. A rinse solution is supplied for a short time period in a pipe system 11 where the rinse solution flows without difficulty so as not to take much time for the rinse step. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
