In the global pharmaceutical market, precision in solid dosage packaging is mandated by strict regulatory frameworks. Whether you are producing for the US market under FDA 21 CFR Part 211 or the European market under EudraLex Volume 4, your equipment must guarantee that every bottle contains the exact prescribed count — no more, no less.

1. Material Integrity and Hygienic Design (cGMP)
According to cGMP principles, any machine part that comes into direct contact with the product must be non-reactive, non-absorptive, and non-contaminating.
Key Requirements:
- Surface Finish: Smooth surfaces with Ra ≤ 0.8 μm to prevent microbial growth
- Material: SUS304 or 316L stainless steel for all product-contact parts
- Cleanability: Tool-less disassembly of contact parts for cleaning validation
Case Study — SED-8S: The SED-8S Automatic 8-Channel Electronic Counting Machine utilizes a corrugated vibrating plate design to move tablets and capsules. All contact parts can be disassembled without tools, facilitating the Cleaning Validation required by GMP to prevent cross-contamination during product changeovers.
2. The Challenge of Dust Integrity in Counting
Common Audit Failure Point: One of the most frequent causes of audit failure in counting lines is inaccurate tallies caused by ambient dust from uncoated tablets or friable capsules. Sensors must be able to distinguish between a solid dosage form and airborne particulates.
To meet these high standards, the SED-8S is equipped with proprietary anti-high dust photoelectric sensing technology. Even in environments with significant powder shedding, the counting logic remains stable and the error rate stays below international thresholds.
The SED-8S features 8-channel electronic counting with anti-high dust photoelectric sensors for GMP-compliant accuracy.
3. The Validation Roadmap: DQ, FAT, IQ, OQ, PQ
A compliant machine must be accompanied by a validation lifecycle that proves it is fit for its intended use. Below is how a professional validation process should be structured, using the SED-8S as a benchmark.
DQDesign Qual.
FATFactory Accept.
IQInstall Qual.
OQOperational Qual.
PQPerformance Qual.
DQDesign Qualification
Validates that the proposed equipment design meets user requirement specifications (URS) before manufacturing begins. This is the foundation — confirming the machine concept matches the intended application, batch sizes, product characteristics, and regulatory environment.
FATFactory Acceptance Test
Before the machine leaves the supplier, a FAT is conducted to ensure the build matches the Design Qualification and URS.
SED-8S Example: Engineers verify the production speed achieves the promised 10–40 bottles/minute and that SICK sensors correctly identify Bottle Jams or No Bottle scenarios. The machine runs under load conditions with the customer’s actual product whenever possible.
IQInstallation Qualification
IQ verifies that the equipment is installed in an environment that supports its technical needs and that all components match the purchase order specifications.
SED-8S Example: IQ documentation tracks the verification of the 220V/50Hz power supply and connection to a 0.6 MPa compressed air source with a flow rate of 3.5 L/min. All utilities, clearance spaces, and environmental conditions (temperature, humidity) are documented.
OQOperational Qualification
OQ tests the machine’s functional limits across the full operating range to identify any upper and lower boundaries where performance degrades.
SED-8S Example: Testing the Delta HMI and Schneider emergency stop circuits. Engineers verify that the 8-channel vibration system delivers uniform flow for various materials — ranging from small pills (5.5 mm) to large capsules (000#). Each channel and sensor array is tested individually across its specified range.
PQPerformance Qualification
PQ proves the machine consistently performs under real-world production loads, with actual products, over extended periods that mirror routine manufacturing conditions.
SED-8S Example: Running three consecutive batches of different dosage forms (e.g., softgels vs. sugar-coated tablets) to ensure counting accuracy remains 100% and the reject gate correctly diverts any miscounted bottles. Batch records and electronic logs are reviewed for completeness and traceability.

Frequently Asked Questions
Can one counting machine be used for both softgels and tablets?
Yes, provided the machine has adjustable vibration frequencies and compatible channel widths. The SED-8S Automatic 8-Channel Electronic Counting Machine is designed with this versatility, handling everything from transparent softgels to large 000# capsules through its intelligent sensor array and programmable vibration profiles.
How do I ensure my counting line is 21 CFR Part 11 compliant?
Look for machines with PLCs that support multi-level user access and unalterable electronic logs. The SED-8S uses a centralized control system where operating parameters can be locked, ensuring only authorized personnel can change batch settings. Combined with secure audit trails, automatic data logging, and electronic signature capability, it provides a foundation for 21 CFR Part 11 compliance.
What is the typical footprint for a mid-speed counting line?
For a machine like the SED-8S, you should budget space for the integrated conveyor system plus clearance for operator maintenance and cleaning access. Contact SED Pharma for detailed CAD drawings and specific installation dimensions based on your facility layout.
Conclusion
Achieving full regulatory compliance in pharmaceutical packaging requires more than just a fast counting machine. From material integrity and dust-resilient sensors to the complete DQ–FAT–IQ–OQ–PQ validation lifecycle, every element must work together to produce consistent, auditable results. The SED-8S demonstrates how a purpose-built machine with the right validation documentation can help manufacturers meet FDA, EU GMP, and global standards with confidence.
