In tablet manufacturing, some of the largest hidden production losses occur during changeovers.
Production stops, tooling is removed, equipment is cleaned, operators inspect surfaces, QA reviews readiness, and only then can the next product begin. When cleaning is slow or inspection confidence is low, valuable hours are lost.
For many facilities, the bottleneck is not production capacity—it is cleaning efficiency and equipment release speed.
A modern three-part approach using Sahara® foam wipers, MiraWIPE® microfiber wipers, and PolyCHECK® inspection wipes and swabs with UV light can significantly reduce downtime while improving cleanliness assurance.
Why Changeovers Take Too Long
Common delays include:
1. Hardened Residues
Powders, binders, lubricants, and coating residues accumulate on:
- Tablet presses
- Feed frames
- Punches and dies
- Turrets
- Hoppers
- Change parts
- Stainless product-contact surfaces
2. Hard-to-Inspect Surfaces
Residues hide in:
- Corners
- Threads
- Punch engravings
- Score lines
- Micro-scratches from wear
- Areas damaged by prior abrasive scrubbing tools
3. Recleaning Due to Uncertainty
If operators or QA are unsure whether surfaces are clean, equipment is often wiped again.
Step 1: Faster Residue Removal with Sahara®
Sahara® foam wipers provide Scotch-Brite®-like scrubbing performance while remaining scratch-free on stainless steel and electropolished stainless surfaces.
This allows operators to remove dried product films and stubborn residues aggressively without damaging expensive equipment surfaces.
That matters because scratched surfaces become harder to clean over time.
Step 2: Deep Final Cleaning with MiraWIPE®
MiraWIPE® is not a standard cleanroom wipe.
Its woven microfiber fabric and tear-proof sealed edge were designed for heavy-duty equipment cleaning where microscopic solids, APIs, grease-coated particles, and product residues must be removed—even from worn surfaces or micro-scratches caused by previous cleaning abuse.
MiraWIPE® helps remove contamination generic wipes often smear or miss.
Step 3: Rapid Verification with PolyCHECK® + UV Light
After cleaning, operators wipe critical areas using PolyCHECK® wipes or swabs.
When illuminated with UV light, residues captured on the PolyCHECK surface often fluoresce, helping operators determine whether organic residues still remain on the tool surface.
This gives teams fast feedback:
- If clean → proceed to release
- If residue remains → re-clean only targeted area
Additional Benefit: Lower Tablet Quality Defects
Sahara® + MiraWIPE® can also help reduce tablet defects caused by foreign material (FM).
Tablet presses often hide:
- Dark particles
- Grease-coated contamination
- Metallic fines
- Powder agglomerates
- Residues lodged in inaccessible areas
These contaminants can later dislodge and embed into tablets.
Improved cleaning removes these hidden defect sources before the next batch starts.
Results Facilities Can Expect
- Faster changeovers
- Higher OEE
- Less recleaning
- Better QA confidence
- Lower FM-related tablet defects
- More predictable production scheduling
Final Thought
Many tablet plants focus on making tablets faster. The smarter opportunity is often getting the press back online faster.
