Granulation, tableting, coating and packaging lines proven under process validation
Commissioning, qualification and validation software for oral solid dose where granulators, tablet presses, coaters and packaging lines all have to prove capability before process validation batches ship.
An oral solid dose (OSD) line moves powder through granulation, blending, compression, coating and packaging, each stage with its own equipment qualification, in-process control and cleaning validation requirement. Deskely holds every piece of equipment, cleaning procedure and packaging line component in one register with IQ, OQ, PQ and process validation gates built in.

The problem
Granulation, compression, coating and packaging, each stage with its own vendor and its own cleaning validation, and a spreadsheet cannot show which stage is holding up PV.
An OSD line is a sequence of discrete equipment — high-shear granulators, fluid bed dryers, tablet presses, coating pans and packaging lines — each installed and qualified by a different vendor on a different schedule, with cleaning validation and changeover procedures layered across every product changeover.
When equipment IQ/OQ records, cleaning validation swab results and packaging line qualification sit in separate quality and engineering files, nobody can confirm which stage of the line is actually ready to run a process validation batch.
Deskely tags every granulator, press, coater and packaging component individually, so PV readiness is reported stage by stage instead of assumed from a line-wide status update.
Setting up the register
Granulators, presses, coaters and packaging lines are tagged assets matched to the equipment train layout.
Equipment layout drawings, P&IDs for dust containment and material transfer, and vendor equipment lists are parsed into a reviewed register, so every granulator, press and coater carries its URS, its cleaning validation matrix reference and its vendor FAT data from day one.
IQ, OQ and PQ protocols are templated once per equipment type and instantiated across every unit on the line, so a new tablet press or coating pan inherits the approved test set rather than starting from a blank document.
Cleaning validation is held as its own record type against each product-contact surface, tracking swab and rinse sample results against acceptance limits for every product changeover the equipment will see.
Execution
Equipment qualification, cleaning validation and PV batches are gated stage by stage across the line.
IQ confirms every granulator, press, coater and packaging component is installed to specification; OQ proves each unit performs across its full operating range, including tablet weight, hardness and dissolution-relevant compression force settings.
Cleaning validation runs are executed and sampled against every product-contact surface before a changeover is cleared, with swab results logged against the specific equipment tag rather than a line-wide cleaning log.
Process validation batches are executed against the qualified line, with in-process controls, blend uniformity and dissolution data tracked batch by batch, and any deviation logged against the specific stage that produced it.
PV completion and release to commercial manufacturing
The line is released to commercial production from three consecutive PV batches with signed, traceable evidence, not a batch record summary.
Process validation completion draws on IQ/OQ status, cleaning validation results and PV batch data across the whole line, so the evidence a quality unit needs for the validation report is an export rather than a cross-departmental assembly exercise.
The handover pack for manufacturing includes as-built equipment qualification records, cleaning validation matrices and PV batch summaries keyed to the line, giving operations the same record used to validate it.
Every signature carries a name, role and timestamp, which is what a quality unit and a regulatory pre-approval inspection expect before an OSD line is declared validated for commercial supply.
Cross-contamination and changeover control
The same press runs three products in a month, and a missed swab result on one changeover is a cross-contamination event, not a paperwork gap.
Shared equipment trains are the economic reality of an OSD facility, but every product changeover carries a cross-contamination risk that a dedicated single-product line does not: residual API from the previous product has to be shown, by sampled evidence, to be below the acceptance limit before the next product is charged.
When cleaning validation sampling is logged in a paper cleaning log kept next to the machine, a changeover can be signed off as complete before the lab has actually reported the swab result, because the two records live in different places and nobody is forcing the sequence.
Deskely blocks the next batch record from opening on a shared piece of equipment until the cleaning validation result for that specific product-contact surface and changeover is logged and within limits, so the sequence that protects against cross-contamination is enforced by the system rather than by an operator remembering to check.
The tablet and capsule dossier
The paperwork granulation, compression and coating equipment has to clear before validation.
Oral solid dose lines move product through granulation, compression, coating and packaging, and each unit has its own qualification burden around content uniformity, dust containment and change-part control. The dossier ties equipment testing to the process validation batches that establish a robust design space.
Granulator, tablet press and coater IQ, OQ reports
Speed, force, spray rate and airflow hold within the ranges set by the design of experiments.
Before engineering runs and PPQ.
Process validation (PPQ) batch records
Three consecutive batches meet content uniformity, dissolution and hardness specifications.
Following successful OQ and prior to commercial release.
Cleaning validation swab and rinse results
Cross-contamination risk between products is controlled to calculated carryover limits.
After each cleaning validation study and on product changeover.
Dust containment and OEB verification reports
Occupational exposure limits are met at charging, discharge and sampling points.
Commissioning of containment equipment and periodic revalidation.
HVAC and room classification particle count reports
Manufacturing suites hold the classification needed to protect product from environmental contamination.
Qualification and scheduled requalification.
CSV audit trail review for weighing and dispensing systems
Formula and batch data entries are attributable, time-stamped and unaltered.
System go-live and periodic Part 11 review.
How it runs
From equipment FAT to three consecutive PV batches.
OSD programmes reward a register that ties cleaning validation to the specific equipment surface, because a missed swab result on one press is what a regulatory inspection is designed to catch.
