The document discusses validation of a fluidized bed dryer. It describes the purpose of equipment validation and the typical stages: installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ). For a fluidized bed dryer, IQ involves installing the equipment according to specifications. OQ involves testing that the dryer operates as intended under normal conditions. PQ involves drying product batches and ensuring the dryer reduces moisture content as specified and maintains quality/quantity of output. The document provides details on procedures, acceptance criteria, and revalidation for each qualification stage of the fluidized bed dryer.

- 1. VALIDATION OF FLUIDIZIED BED DRYER
- 2. Content: Why to validate? Parts of Equipment Validation Who should do Equipment Validation? Equipment qualification Typical process flow of solid dosage form Validation of fluid bed dryer 2
- 3. Why to validate? Equipment validation is Vital for • Safety • Fewer interruptions of work • Lower repair costs • Elimination of premature replacement • Less standby equipment • Identification of high maintenance cost • Reduction of variation in results • Greater confidence in the reliability of results 3
- 4. Parts of Equipment Validation Equipment Validation Installation Qualification (IQ) Operational Qualification (OQ) Performance Qualification (PQ) Design Qualification (DQ) 4
- 5. Who should do Equipment Validation? The vendor or the user? The user has the ultimate responsibility for equipment qualification. DQ should always be done by the user. While IQ for a small and low cost instrument is usually done by the user, and IQ for large, complex and high cost instruments should be done by the vendor. OQ can be done by either the user or the vendor. PQ should always be done by the user 5
- 6. Equipment qualification Equipment qualification / validation includes following things : • Design qualification (DQ) • Installation qualification (IQ) • Operational qualification (OQ) • Performance qualification (PQ) 6

- 12. Installation Qualification(IQ) Installation Procedure: After checking all the specifications as mentioned in the selection criteria, service engineer of the manufacturer shall be called for commissioning, if necessary. Authorized validation team shall carry out installation. Department Head of production, QA & engineering shall evaluate installation report 12
- 13. Conti… Acceptance Criteria For Installation Qualification: The equipment shall fulfill the selection criteria & its purpose of Application. Name of the manufacturer & supplier shall be as mentioned in the Purchase order The manufacturer/supplier shall provide complete equipment manual along with the equipment All recommended utilities of recommended capacities are to be provided near the place of installation 13
- 14. Conti… Revalidation Criteria The equipment shall be revalidated if; Location of the equipment is changed. There is change of spare/parts,major maintenance or breakdown that have a direct effect on the performance of the equipment 14
- 15. Conti… Conclusion: The equipment shall be considered qualified for installation provided it meets all the parameters mentioned in the acceptance criteria. After receiving installation report, it shall be evaluated & released for operational qualification, provided installation report is evaluated & the equipment is found meeting all parameters of acceptance criteria 15
- 16. Operational Qualification (OQ) Training record Before initiating OQ ensure that SOP for Cleaning and operation of FBD is available. • Purpose: To train the qualification team for performing OQ 16
- 17. Conti… Procedure Initiate the actual operation of the FBD to ensure that machine is operating within specification. Check the OQ parameters against their specifications. Observe the functioning of all controls available on control panel Record the observation Perform and attach report of heat distribution study as per ` Heat distribution study procedure’ 17
- 18. Conti… Acceptance criteria (Heat Distribution Study:) Temperature difference between all thermocouples and set temperature should not differ by more than ± 5 °C. All operating inputs provided on the equipment when tested shall-successfully comply -meet tolerance limit The equipment should successfully perform when operated as per SOP 18
- 19. Conti… Critical gauges/indicators provided on the equipment---calibrated The equipment when operated shall not - produce abnormal sound - show any discrepancy in its smooth operation. 19
- 20. Conti… Revalidation Criteria: The equipment shall be revalidated if; Location of the equipment is changed. There is change of spare/ parts, major maintenance or breakdown that have a direct effect on the performance of the equipment Critical gauges shall be replaced or corrected At normal revalidation schedule. 20
- 21. Performance Qualification(PQ) To check Heat Distribution by placing 10 thermocouples in geometric pattern with the FBD Shell and empty Product Container without any load to ensure heat distribution in the drying chamber Heat distribution study will be performed at 65 ± 5°C for two hour after achieving the temperature on the controlling sensors to ensure proper heat distribution. 21
- 22. Conti… Procedure After completion of OQ initiate the PQ of FBD. The effectiveness of drying will be qualified by determining reduction of % moisture content in drying process. 3 batches/ lots of any product will be taken for PQ of FBD. At least 2.0 gm of sample is sampled for % MC check from the top, middle and bottom trays and will be reported 22
- 23. Conti… In case of any deviation inform to department head for necessary action Document the deviation details Deviation is acceptable or not will be decided -if yes -if not 23
- 24. Conti… Acceptance criteria The reduction in moisture content after drying should be as per the specification in the BMR % RSD of LOD should not be more than 6 % The equipment should produce intended outputs with respect to quality & quantity consistently 24
- 25. Conti… Revalidation Criteria: The equipment shall be revalidated if; Location of the equipment is changed. There is change of spare/ parts, major maintenance or breakdown that have a direct effect on the performance of the equipment At normal revalidation schedule. 25
- 26. Procedure for Drying Efficacy Study in Fluidized bed Dryer: Ensure the cleaning of machine Load the wet mass in the FBD product container Set the process time & outlet temperature and run the FBD. After completion of drying take out FBD bowl and collect the sample At least 2.0 gm of sample is sampled for % MC check from the top, middle and bottom trays and will be reported 26
- 27. Conti… Sampling Procedure: Ware nose mask, hand gloves before sampling. Label the sample bag with details as Product name, stage, date, time and sign Collect app. 2.0 gms of dried material composite sample in poly bag as per location shown Record the details of analysis. 27
