Modular Intelligent Filling System Empowers End-to-End Automation: Spiral Metering + Pneumatic Capping Technology Solves Dual Bottlenecks of Precision and Efficiency in Small-Batch Production

Guangdong Rifu Intelligent Equipment Co., Ltd. (hereinafter referred to as "Rifu Intelligent") announced today the successful commissioning and market launch of its self-developed medical-grade semi-automatic capsule filler. Designed for small-to-medium batch production in healthcare, dietary supplements, and veterinary medicine industries, this equipment achieves automated operations for core processes including capsule orientation, powder metering, and precise capping through a modular intelligent filling system. It bridges the gap between traditional manual filling and fully automatic equipment, offering cost-effective intelligent solutions for laboratory R&D, clinical trials, and small-to-medium pharmaceutical enterprises.
- Vibratory Bowl Dynamic Feeding Technology: A customized vibratory bowl enables disordered feeding and high-speed sorting of capsule shells. Material-contact guide channels and distribution trays are constructed from food-grade 304 stainless steel, ensuring a capsule feeding pass rate of ≥99.8%.
- Vacuum Adsorption Separation Mechanism: Using negative pressure airflow and mechanical grippers, this mechanism accurately separates capsule bodies and caps into upper/lower mold stations. With a separation speed of 800 capsules per minute and a 100% success rate, it resolves long-standing industry issues of low efficiency (only 150 capsules/minute) and high waste (≥5% loss rate) in manual separation.
- Spiral Precision Metering Device: Equipped with a dual-spiral powder feeding mechanism driven by a German imported servo motor, it supports free switching across 00#-4# capsule sizes (corresponding to 0.1-5g filling volumes). Using a three-level density compensation algorithm, powder filling accuracy reaches ±0.5% (CV value), a 300% improvement over traditional manual filling, suitable for materials with varying flowability such as probiotic powders and Chinese herbal extracts.
- Intelligent Tamping Technology: Integrating three-stage processing—high-frequency vibratory bowl pre-tamping, linear vibrator secondary homogenization, and rotational tamping rod pressure forming—this technology ensures powder density variation within ±2% in capsules, effectively solving problems like layering and empty caps, especially critical for controlled-release formulations and enteric-coated capsules with strict uniformity requirements.
- Pressure Closed-Loop Capping Technology: A pneumatic servo pressing mechanism monitors capping pressure in real-time (control accuracy ±0.05N·m). Combined with anti-stick coated molds, it guarantees a 100% capping success rate, eliminating powder leakage and jamming. The automatic capping process takes <2 seconds per cycle, 8 times faster than manual operations.
- Rapid Demolding Design: After capping, the mold automatically tilts to the unloading station, and a pneumatic ejector pin array pushes out finished capsules synchronously within <1 second, supporting continuous operation and significantly reducing downtime.
- Clean Process Architecture: All material-contact components use 316L stainless steel (for powder-contact parts) and medical-grade PTFE coated materials, with surface roughness Ra≤0.6μm. Capable of withstanding CIP (in-situ cleaning) and SIP (steam sterilization), it complies with FDA 21 CFR Part 11, EU GMP Annex 11, and China NMPA Good Manufacturing Practice requirements.
- Flexible Mold Changeover Capability: The innovative quick-release mold system uses magnetic positioning and threaded locking to switch between 00#-4# capsule molds in 10 minutes, supporting rapid 规格转换 for different capsule sizes and adapting to flexible needs from laboratory R&D (500 capsules/batch) to small-batch production (5,000 capsules/batch).
- Dust Suppression Solution: Equipped with a standard negative-pressure dust collection system, a detachable sealed hood at the filling station, and a high-efficiency filter (0.3μm filtration accuracy), it controls workplace dust concentration below <0.1mg/m³—3 times better than national standards—ensuring a clean production environment.
Testing by a leading dietary supplement enterprise demonstrated exceptional performance:
- Capacity Boost: Processing 32,000 capsules per 8-hour shift—5 times the output of manual operations—with human intervention reduced from 12 times per batch to just 1, significantly lowering labor intensity.
- Quality Control: Powder filling standard deviation controlled within ±0.08g (for 2g specification), capping torque fluctuation ≤±0.03N·m, and powder leakage rate <0.05%—key metrics exceeding industry standards by 30% or more.
- Cost Optimization: Filling cost per capsule decreased from 0.05 RMB to 0.01 RMB, with labor requirements reduced from 3 operators per shift to 1, shortening the equipment payback period to 6 months and becoming the preferred choice for 智能化 transformation in small-to-medium pharmaceutical enterprises.
As a leading enterprise in China's intelligent packaging equipment sector, Rifu Intelligent relies on a provincial-level engineering technology research center and holds 12 invention patents, establishing three core advantages:
- Precision Metering Technology: The self-developed spiral powder feeding algorithm, certified with national patents, automatically adjusts feeding speed based on material flowability, adapting to over 98% of powdered materials—including moisture-sensitive and high-static substances.
- International Compliance Capability: The equipment meets CE, ISO 13485, and other certifications. A specially developed electronic regulatory code encoding module for the EU market enables seamless integration with pharmaceutical MES systems, satisfying compliance requirements in major global markets.
- Full Lifecycle Service: Equipped with a dedicated customer service team and remote diagnostic system, it ensures 48-hour rapid response for critical components, maintaining equipment utilization rate ≥98%.
