Rapid mixture Granulator SOP to be followed in the granulation section in the production department at Pharmaceuticals

SOP file cover for Rapid Mixture Granulator cleaning and procedure

1.0 Purpose: To lay down SOP on Rapid Mixture Granulator for Operation and Cleaning.
2.0 Scope: This SOP applies to RMG operation and cleaning In pharmaceuticals.
3.0 Responsibility: 3.1 Operator, Officer Production is responsible for the implementation of this SOP.
3.2 Head Production is responsible for ensuring compliance with this SOP

4.0 Checkpoint :

4.1 Check the Cleanliness of RMG before starting the Operation. Check that Compressed Air Couplings are correctly fitted.
4.2 Ensure that the primary Compressed Air Pressure is 3 – 6 bar.
4.3 Ensure the Limit Switches (Interlocks) are working correctly.
4.4 Check that Impeller and Chopper are correctly fitted.
4.5 Check that the Calibration Validity of pressure gauges, hydraulic gauges, RPM indicators, and temperature sensor is not exceeding the Due Date.
4.6 Use product dedicated Air Vent Filter Bag.
4.7 Check the Integrity of the Fluidized Bed Drier Bowl Sieve Visually before use.
4.8 Check the Integrity of the Cone Mill Screen if used before and after use.
4.9 Ensure the operating panel purging is not more than 0.5 kg /cm2 and chopper air purging and beater air purging pressure is between 0.5 – 1.0 bar.

5.1 Raw Material Discharging:

5.1.1 Place the Fluidized Bed Drier Bowl below the Discharge port.
5.1.2 Unlock the lid, clamp the lid clamps and open the top of RMG with the help of the handle provided on the cover.
5.1.3 Unload the Raw Material in the Rapid Mixer Granulator manually.
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 Polybag before starting the Cleanin Remove the “To Be Clean” Status Label from 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 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 to 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 the Rapid Mixer Granulator with a dry Lint-Free Duster followed by 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 Procedure for Calibration

7.2.1 Set the RPM of the 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 the 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 the Peristaltic Pump should not be more or less than 1 RPM.
