| dc.description.abstract | Flushing is an urging process to help water or material transportation in pipe. Flushing consisted of initial flushing and end flushing. Verification is a method of flushing efficiency. Industry never verified flushing before, so the aims of this internship were to verify flushing from storage tank to filler machine, to know initial flushing reduction in a month production and saving material at end flushing. Parameter used for verification is total solid. Industry used 90 liters from T500 and 95 liters from T501 for initial flushing, and 32 liter for end flushing without distinguished tank. After verification, for initial flushing from T500 needs 88 liters and from T501 needs 84 liters, otherwise for end filling can only save 28 liters. Therefore, material reductions for initial flushing are 2 liters from T500 and 11 liters from T501, but at end flushing can not save more material because of product quality. Assumed that stirred yogurt production 5 times in a month, then the amount of material reduction for flushing at least 10 liters/month. | en |
