Automatic Servo Softgel Encapsulator

Servo-driven softgel encapsulation machines offer several fundamental advantages over mechanically driven systems. First, servo control enables significantly higher operating speeds-the VIT16SF reaches 10 rpm versus 4–5 rpm for typical mechanical machines, effectively doubling production capacity. Second, servo systems provide automatic die alignment, digital fill adjustment, and real-time thickness control, dramatically reducing setup time and material waste during changeovers. Third, all-electric servo drivetrains have fewer wearing parts, resulting in lower maintenance, reduced downtime, and the demonstrated sub-0.5% failure rate. Finally, digital process control enables recipe management, batch data recording, and easier integration with plant automation systems-all increasingly important for cGMP pharmaceutical manufacturing.

The VIT16SF's automatic die alignment uses precision servo motors on both left and right main spindles to index the die rolls into perfect registration. The operator simply initiates the alignment sequence from the touchscreen, and the servo system automatically centers and synchronizes both die sets. On conventional softgel machines, manual die alignment can take 1–3 hours of skilled technician time per changeover. The VIT16SF completes this process in minutes, significantly increasing equipment availability for facilities running multiple products or frequent size changeovers.

Yes, the VIT16SF is engineered and tested for 24-hour uninterrupted production operation. The all-servo drivetrain with custom harmonic reducers is designed for continuous duty without the heat buildup and wear that limit mechanical machines. Field operational data confirms stable performance and consistent capsule quality across extended production runs, with a demonstrated failure rate below 0.5%. For facilities running multi-shift operations, this continuous production capability can increase annual output by 30–50% compared to machines rated for single-shift operation only.

The VIT16SF delivers a theoretical output of 241,920 capsules per hour for size 8 Oval capsules at 8 rpm operating speed. Sustained real-world production rates typically range from 75–85% of theoretical capacity, depending on formulation characteristics, operator efficiency, and planned stops for quality checks or material replenishment. This translates to approximately 180,000–205,000 capsules per hour in typical pharmaceutical production environments. For reference, this is roughly double the sustainable output of standard 5 rpm mechanical softgel encapsulation machines.

The Siemens S7-1510T Technology CPU is a fully industrialized PLC platform with standard PROFINET, Ethernet/IP, and OPC UA communication capabilities, enabling straightforward integration with most pharmaceutical SCADA systems, manufacturing execution systems (MES), and plant historian platforms. The technology PLC also supports advanced motion control and comprehensive data logging functions required for regulatory compliance. Schneider PLC option is available for facilities with standardized Schneider automation architectures. We can provide detailed communication protocol specifications during the quotation phase to support your IT/OT integration assessment.

On conventional softgel machines, establishing and maintaining correct gelatin ribbon thickness requires repeated manual adjustments and trial runs, generating significant waste gelatin solution during startup and formulation transitions. The VIT16SF's closed-loop thickness control system automatically targets the specified thickness value entered by the operator, using real-time sensor feedback to dynamically adjust parameters. This automated control reduces gelatin waste during machine startup and product changeovers by an estimated 60–70% compared to manual adjustment, while also maintaining more consistent ribbon thickness throughout production runs-directly improving capsule weight uniformity and reducing reject rates.

Servo-driven softgel machines actually have lower maintenance requirements than mechanically driven machines because they eliminate many high-wear components like gears, cams, and mechanical linkages. The primary maintenance activities for the VIT16SF include periodic lubrication of bearing assemblies, inspection of seals and gaskets, calibration verification of fill pumps, and standard electrical system checks. The harmonic reducers are designed for long service life with minimal maintenance. We provide a comprehensive preventive maintenance schedule with recommended intervals based on operating hours, along with spare parts recommendations for on-site inventory.

The VIT16SF uses the industry-standard 6" × 10" (Φ150 mm × 250 mm) die roll format, which is compatible with tooling from most major softgel equipment manufacturers using this common working width specification. This means pharmaceutical and nutraceutical producers with existing inventories of oval, oblong, or custom-shaped die tooling can often transfer those tooling sets to the VIT16SF platform, reducing capital investment when upgrading from older machines. We recommend tooling compatibility verification during the evaluation phase to confirm dimensional compatibility with your specific tooling supplier's products.

ROI for the VIT16SF depends on current production volume, labor costs, and material waste rates, but most high-volume producers achieve payback within 18–30 months. The primary ROI drivers are: doubled production capacity versus conventional machines (increasing revenue potential), 60–70% reduction in gelatin waste during changeovers, reduced labor for setup and adjustment (one operator can manage the automated system), lower maintenance and downtime costs, and improved yield from tighter process control. For contract manufacturers, the faster changeover capability also enables accepting more product campaigns per year. We can assist with a customized ROI analysis based on your specific production profile.

We provide comprehensive validation documentation packages to support pharmaceutical GMP qualification activities. The standard documentation package includes equipment functional specifications, design qualification (DQ) documentation, material certificates for product-contact components, electrical schematics, and factory acceptance test (FAT) protocols. Optional documentation packages support Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) execution, including template protocols and test reports. Our technical validation team can also provide on-site support during commissioning and qualification activities as needed. The Siemens PLC platform's built-in data logging and audit trail capabilities support ongoing data integrity compliance under 21 CFR Part 11 and Annex 11 requirements.
