5.1.4 Close the Lid of RMG and tighten the Clamp.
6.0 Before Cleaning Procedure: Affix the “To Be Clean” Status Label on the Rapid Mixer Granulator if cleaning of RMG is to be performed after the discharging of Wet granules.
6.1 Pre-Cleaning Checks for SOP on Rapid Mixture Granulator:
6.1.1 Put <OFF> the Mains Switch of the Rapid Mixer Granulator.
6.1.2 Cover the Control Panel with a Polybag before starting the Cleanin Remove the “To Be Clean” Status Label from the Rapid Mixer Granulator.
6.1.3 The operator shall visually check the location for cleaning of hard-to-access and hard-to-clean areas in steps to ensure consistency in the cleaning procedure.
6.2 Post-Cleaning Checks :
6.2.1 After the cleaning operator visually checks the location 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 Rapid Mixture Granulator:
6.3.1 Unlock the clamps of RMG to open the lid, then scrape and collect any powder from the Rapid Mixer Granulator, transferring it to a dedicated container labeled as “Non-Recoverable.”
6.3.2 Disconnect the air supply to the spray gun, the silicon tubing, and the spray gun, transferring them 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, passing it through the silicon tubing until visually clean, 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 tubing by hanging them inverted on a hanger meant for hose pipe storage.
6.3.6 Clean the External Surface of the Rapid Mixer Granulator with a dry, lint-free duster followed by a lint-free duster soaked in purified water.
6.3.7 Clean the control panel with a dry lint-free duster, close the lid, lock the clamps of RMG, and affix the duly filled “Cleaned” Status Label on Rapid Mixer Granulator.
6.3.8 Record the cleaning activities in Equipment Logbook as per SOP “Procedure for making entry 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 Calibration Procedure:
7.2.1 Set the RPM of the Peristaltic Pump in the PLC from 20 to 220 as specified in Annexure-I.
7.2.2 Start the Peristaltic Pump and record the reading on the Digital Display of the Peristaltic Pump according to Annexure-I.
7.2.3 Apply the Reflecting Mark to the squeezing Roller Bracket of the Peristaltic Pump.
7.2.4 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.
7.2.5 Start the Peristaltic Pump and set the RPM.
7.2.6 Ensure that the reflecting mark coincides with the photo signal light beam when it passes through the light beam.
7.2.7 Release the Operation button when the reading stabilizes.
7.2.8 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.
7.2.9 Note down the reading of each Display RPM on the Tachometer as per Annexure I.
7.2.10 Ensure that the difference between the Display RPM on the Tachometer and the Display RPM on the digital display of the Peristaltic Pump is not more or less than 1 RPM.
