Brief Description

This Installation Qualification (IQ) Protocol cum Report is prepared for the Rapid Mixer Granulator (RMG) used for dry mixing and wet granulation of pharmaceutical materials. The main purpose of this document is to confirm that the equipment is installed correctly, matches the approved design and specifications, and follows cGMP requirements. The RMG has a gross capacity of 600 liters and is supplied by Elicon Pharma. The qualification includes checking required documents, equipment location, mounting, leveling, electrical supply, compressed air, material of construction, drawings, technical specifications, and installation connections. It also verifies important parts such as the mixing bowl, main impeller, chopper, motors, PLC, discharge system, control panel, staircase, and safety features. Safety checks ensure the machine does not run under unsafe conditions. Any deviation or change found during qualification must be recorded and reviewed. After successful completion, the equipment can be recommended for further qualification and routine use in production.

Impact Assessment

This Installation Qualification of the Rapid Mixer Granulator will have a positive impact on equipment reliability, product quality, and operator safety. It confirms that the RMG is installed correctly and matches the approved design, technical specifications, and cGMP requirements. Important checks include equipment location, mounting, leveling, electrical supply, compressed air, material of construction, drawings, major components, and installation connections. Safety features are also checked to ensure the machine does not operate when unsafe conditions are present, such as low air pressure, an open lid, open discharge port, motor trip, or emergency stop activation. Proper qualification reduces the risk of equipment failure, contamination, unsafe operation, and production problems. It also helps Production, Engineering, and Quality Assurance confirm that the machine is suitable for further qualification and routine use. Overall, the IQ provides documented evidence that the RMG installation is safe, controlled, and ready for reliable pharmaceutical manufacturing operations in the facility.

Critical Process Parameters (CPPs) – Rapid Mixer Granulator

Based on the attached RMG IQ document, the following operating parameters are relevant to the mixing and granulation process:

Critical Process Parameter	Importance
Main impeller speed	Controls mixing and distribution of material
Chopper speed	Helps break lumps and control granule formation
Mixing time	Ensures proper and uniform mixing
Wet granulation time	Controls formation of the required granules
Binder addition	Influences granule formation and consistency
Granulation end point / motor ampere	Helps identify completion of wet granulation
Working capacity	RMG working capacity is specified as 480 L
Chopper RPM	Specified as 1430/2900 RPM
Compressed air pressure	Required pressure is 6 bar
Electrical supply	415 V ±10%, 50 Hz ±5%
Impeller clearance	Bottom: 1–2 mm; Side: 5–7 mm

The protocol states that the main impeller and chopper operate at slow/fast speeds according to process requirements, with process duration controlled by a timer. Wet granulation is monitored through the motor ampere reading. Technical specifications and impeller clearances are also defined in the IQ.

Critical Quality Attributes (CQAs)

For an RMG wet-granulation process, typical CQAs from general pharmaceutical practice may include:

• Blend uniformity
• Granule size distribution
• Moisture content / Loss on Drying
• Granule bulk density
• Tapped density
• Flow properties
• Granule appearance
• Assay / drug-content uniformity
• Compressibility of granules
• Absence of excessive lumps or fines

These CQAs should be finalized from the product-specific Process Validation Protocol, MFR/BMR, development report, and finished-product requirements, rather than from the Installation Qualification document alone.

FMEA Risk Assessment – Rapid Mixer Granulator Installation Qualification

The FMEA below is based on the installation checks, utilities, MOC verification, technical specifications, and safety requirements given in the attached RMG IQ protocol.

Scoring: Severity (S), Occurrence (O), Detection (D) = 1–5; RPN = S × O × D.
The numerical scores below are suggested risk ratings; the IQ document itself does not provide FMEA scores.

S.No.	Failure Mode / Risk	Possible Effect	Possible Cause	Existing Control / Check	S	O	D	RPN	Recommended Action
1	Improper grouting or mounting	Vibration, unstable operation, equipment damage	Incorrect installation	Grouting and mounting verification	4	2	2	16	Correct mounting before operation
2	Equipment not properly leveled	Poor mixing, vibration, mechanical stress	Improper leveling	Leveling check during IQ	4	2	2	16	Re-level and verify
3	Incorrect electrical supply	Equipment failure or unsafe operation	Wrong voltage/frequency	3-phase, 415 V ±10%, 50 Hz ±5% verification	5	2	2	20	Verify electrical supply before start
4	Loose or unsafe electrical wiring	Electric shock, trip, machine breakdown	Poor electrical connection	Wiring and electrical connection checks	5	2	2	20	Tighten, insulate and protect connections
5	Low or incorrect compressed air pressure	Pneumatic system may not work correctly	Low pressure, leakage	Compressed air pressure specified at 6 bar	4	3	2	24	Check pressure and leakage
6	Contaminated compressed air	Possible contamination or pneumatic malfunction	Oil, water or dust in air	Air required to be oil, water and dust free	4	2	3	24	Verify compressed-air quality
7	Wrong material of construction	Product contamination or corrosion risk	Incorrect component material	MOC verification for bowl, chopper, lid, discharge parts, etc.	5	2	2	20	Verify MOC certificates before approval
8	Loose bolts / incorrect mechanical adjustment	Vibration, breakdown or unsafe operation	Poor assembly	Bolt tightening and mechanical adjustment checks	4	2	2	16	Tighten and recheck all assemblies
9	Pneumatic connections improperly fitted	Failure of lid/discharge movement	Leakage or incorrect fitting	Pneumatic connection verification	4	2	2	16	Correct fittings and perform leakage check
10	Safety interlock failure	Machine may operate under unsafe condition	Interlock or control-system failure	Lid, discharge, low-air, motor-trip and emergency-stop checks	5	2	2	20	Verify all interlocks before qualification approval
11	Incorrect impeller clearance	Mechanical contact, poor mixing or equipment damage	Improper installation/alignment	Bottom clearance 1–2 mm; side clearance 5–7 mm	5	2	2	20	Measure and adjust clearance
12	Required drawings/documents unavailable	Incorrect installation may remain undetected	Incomplete documentation	DQ, P&ID, electrical drawings, technical specifications and MOC certificates verified	3	2	2	12	Complete and approve documents before IQ closure

The protocol specifically requires verification of electrical supply and compressed air conditions. It also specifies MOC checks for major components and product-contact parts. The main impeller clearance is specified as 1–2 mm from the bowl bottom and 5–7 mm from the side. Safety checks require the RMG not to start or run during conditions such as low air pressure, open lid, open discharge, motor trip, or emergency-stop activation.

Overall Risk Conclusion: The identified installation risks are generally controllable through IQ verification. All higher-risk items, especially electrical supply, compressed air, MOC, impeller clearance, and safety interlocks, should be satisfactorily verified before the RMG is released for further qualification.
