Double Wheel Powder Filling Machine

The Double Wheel Powder Filling Machine is a high-precision, rotary-style automated packaging system specialized for dispensing sterile dry powders into small containers, particularly pharmaceutical vials for injectables. It features two independent powder wheels that operate in parallel, enabling higher throughput compared to single-wheel models while maintaining aseptic conditions. This monoblock design integrates powder filling with rubber stoppering/bunging in a single compact unit, minimizing contamination risks and line space. Primarily used in the pharmaceutical industry for filling antibiotics, vaccines, or lyophilized powders, it ensures uniform dosing through vacuum-assisted piston metering. Variants may include laminar airflow integration for Class 100 cleanroom compliance, making it essential for GMP-certified production lines.

Key Features

• Dual Powder Wheel System: Two synchronized rotary wheels, each with 8-12 ports equipped with adjustable pistons for precise volume control. Powder is drawn into ports via vacuum from agitated hoppers, with doctor blades scraping excess for accuracy. This setup allows for single or double dosing (up to 60g) without bridging.

• Vacuum-Assisted Dosing: Employs vacuum plates behind the wheels for consistent powder suction, achieving fill accuracy of ±1% or better for uniform-density powders. Servo-driven wheels ensure smooth rotation and positioning.

• Integrated Stoppering Unit: Automatic pick-and-place or vacuum-based rubber bung insertion post-filling, with options for partial or full stoppering to suit vial types.

• Infeed/Outfeed Handling: Star wheels or turntables for vial indexing, with “No Vial, No Fill” sensors to prevent waste. Conveyor integration for seamless line flow.

• Control and Agitation: PLC with HMI touchscreen for recipe storage, speed adjustment, and diagnostics. Mechanical agitators in hoppers maintain powder flow; optional servo motors for vibration-free operation.

• Hygiene and Safety: All contact parts in SS 316L with FDA-approved materials; cGMP-compliant with dust-tight enclosures, easy disassembly for CIP/SIP, and optional explosion-proof features.

• Enhancements: Inline rejection/sampling systems, heated hoppers for hygroscopic powders, and compatibility with upstream washers/sterilizers or downstream sealers/labelers.

Applications

• Pharmaceutical Injectables: Filling sterile powders like cephalosporins, penicillin, or biotech drugs into vials for lyophilization lines.

• Aseptic Processing: Ideal for high-volume sterile fill-finish operations in cleanrooms, with options for dry syrups or micro-dose powders in bottles.

• Other: Adaptable for nutraceuticals or lab-scale chemical powders, though primarily pharma-focused.

Advantages

• High Throughput: Dual wheels double output over single models, reducing cycle times by 50-100% while keeping accuracy >99%.

• Precision and Compliance: Vacuum/piston system excels with fine, fluffy powders; meets USP/FDA/GMP/CE standards with minimal dust and zero cross-contamination.

• Efficiency: Energy-efficient single-motor drive with imported gears for low vibration; quick changeovers and low maintenance via robust construction.
