the stipulated circulating valve under low temperature must be examined every 12 hours, which takes about 2-3 minitues. the systematic documents will be revised in 2011 so as to deealing with this kind of problems.
a test on the equipment washing water with ph indicator paper must be carried, PH value of the washing water is around 7,it is qualified.
every time the machine stops for washing, the temperature sensor must be transfered into the water bathing pot; a comparison check between the temperature sensor and standard thermometer will be carried out with the temperature of the water bathing pot rising from room temperature to 100 celsius.

Low Temperature Circulation Valve will be inspected for 2-3 minutes once per shift(12 hours). Revisions will be made in the FY 2011 for relevant system files with regard to this issue.
Test the rinsing for equipment with PH test papers, OK rinse can be concluded when the value of the test indicates at about 7.
During every machine halt for rinsing, move the temperature sensor into a water-bath and verify it in comparison with a standard thermometer as the temperature in the water-bath rises from the room temperature to 100℃.
Stipulated that low temperature circulating valve each class (12 hours)examines one time, require 2-3 minutes time. in 2011 will aim at this question revision system document
Tests with the PH indicator paper to the equipment clear washing water, the PH value namely is qualified about7 for the clean.
Each time the engine off cleans when moves in the water-bath the temperature sensor, when is following the water-bath temperature from often the temperature rise to 100℃, makes thecontrast verification with the standard thermometer.
