6.1.3 The operator shall check the location displayed in the pictorial for cleaning of hard to access and hard to clean the area in step
6.1.4 to ensure consistency in the cleaning procedure.
6.2 Post Cleaning Checks :
6.2.1 After the cleaning operator checks the location mentioned in the below pictorial visually for the clean area.
6.2.2 Close the Discharge Valve opening with a fresh Polybag if Rapid Mixer Granulator is not used immediately after cleaning.
6.3 Cleaning procedure for RMG:
6.3.1 Unlock the clamps of RMG and open the lid and then scrap and collect the powder, if any, from Rapid Mixer Granulator and transfer it to a dedicated container labeled as “Non-Recoverable.”
6.3.2 Disconnect the air supply to the spray gun, disconnect the silicon tubing and spray gun, and transfer the spray gun and silicon tubing wrapped in a polybag to the washroom.
6.3.3 Dedust the Air Vent Filter and clean the peristaltic pump, trolley, and temperature sensor with a dry lint-free duster soaked in purified water.
6.3.4 Dismantle and clean the spray gun with soft water and pass tiro soft water through silicon tubing until it becomes visually clean and then rinse with purified water.
6.3.5 Dry the spray gun with a dry lint-free duster, assemble it to RMG, and dry all the tubing by keeping those in an inverted position on a hanger meant For storage of hose pipe.
6.3.6 Clean the External Surface of Rapid Mixer Granulator with dry Lint-Free Duster followed by Lint Free Duster Soaked in Purified Water.

6.3.8 Record the cleaning activities in Equipment Logbook.
7.0 PROCEDURE FOR CALIBRATION OF PERISTALTIC PUMP:
7.1 frequency of Calibration
7.1.1 Monthly using Digital Tachometer.
7.2 Procedure for Calibration
7.2.1 Set the RPM of Peristaltic Pump in PLC from 20 – 220 as given in Annexure-I.
7.2.2 Start the Peristaltic Pump.
7.2.3 Record the reading on the Digital Display of Peristaltic Pump as per Annexure-I.
7.2.4 Now apply the Reflecting Mark to the squeezing Roller Bracket of the Peristaltic Pump.
7.2.5 Press the Operation Button and align the visible Photo Signal Light Beam of the digital tachometer with the reflecting mark on the squeezing Roller Bracket.
7.2.6 Now, start the Peristaltic Pump and set the RPM.
7.2.7 Ensure that the reflecting mark coincides with the photo signal light beam when it passes through the light beam.
7.2.8 Release the Operation button when the reading stabilizes.
7.2.9 Set the pump’s RPM 20 to 220 at regular intervals of 20 and note down the reading on the Tachometer three times for each set RPM of the Peristaltic Pump.
7.2.10 Note down the reading of each Display RPM in Tachometer as per Annexure I.
7.2.11 The difference between the Display RPM on Tachometer and Display RPM on the digital display of Peristaltic Pump should not be more or less than 1 RPM.
