Automatic packing machine RD-GD-200Pro

vacuumgranularfor the food industry

Overview
Pouch Packing Machine MHW-8/20 integrates an 8–20-head multi-head weigher with intelligent pouch feeding, coding, filling and PID heat sealing. Documentation reports measuring accuracy as ±0.1–1 g (statement) and specification accuracy ±0.5%–1.5%. Standard packing range 200–1,000 g; pouch size W:100–210 mm L:150–450 mm. Documented output: 60 Bags/min; total installed power: 5.0 kW. Product-contact parts are 316L stainless steel; FDA/CE compliance indicated.

Applications

• Pharmaceutical: aseptic packaging of traditional Chinese medicine, granules and other medical products.
• Food industry: quantitative packaging of gummies, nuts, snacks, pet food and other granular products.

Key specifications

• Packing capacity: 200–1,000 g.
• Weigher configuration: 8–20 heads (customizable).
• Measuring accuracy: ±0.5%–1.5% (spec); ±0.1–1 g (statement).
• Pouch size: W 100–210 mm; L 150–450 mm.
• Output: 60 Bags/min (documented; descriptive range up to 60–120 Bags/min depending on model/product).
• Total power: 5.0 kW.

How it works
The machine uses vibration feeders to distribute product to weighing buckets and applies dynamic combination algorithms to reach target weights. Filling is performed via a screw feeder to minimize residue; PID-controlled heat sealing ensures consistent seal quality. The system supports IoT remote maintenance and self-learning compensation; weighing head count and bag formats are configurable for line integration.

Main features

• Multi-head (8–20) combination weigher for fast and precise combination calculation.
• Intelligent combination algorithms to minimize giveaway and maintain weight consistency.
• Modular design for quick changeover (approx. 30 minutes).
• Product-contact surfaces in 316L stainless steel; designed for food/pharma hygiene (FDA/CE indicated).
• Servo-driven mechanisms, PLC and touchscreen HMI for precise synchronization and control.
• Vacuum suction bag picking, infrared positioning and optional nitrogen flushing or air removal.

Main parts / Stages

• Multi-Head Weighing Stage: vibrating plate, weighing buckets, combination control.
