Products Description
Need a maintenance-free vacuum conveyor for small to medium production lines?
Guanjiang's QVC-3 Vacuum Powder Conveyor uses a compressed air-driven vacuum generator (no mechanical vacuum pump) — offering a simple, compact, maintenance-free solution with 300-1500 kg/h capacity and a 12L bin volume. With a φ290×1047mm footprint, it's the ideal step-up from lab-scale models for small to medium pharmaceutical and food production. Features automatic pulse back-blow filter cleaning, GMP compliance, and elimination of material static electricity.
Key Advantages of QVC-3
Delivers 300-1500 kg/h throughput with a 12L bin volume. Perfect bridge between lab-scale R&D and small to medium production lines.
Uses compressed air-driven vacuum generator — maintenance-free, no moving parts, low noise. Simple structure with easy control.
High vacuum prevents material stratification — ensures uniformity of mixed material components for consistent product quality.
Complies with GMP requirements and eliminates material static electricity. Fully enclosed dust-free operation for clean production.
Additional Features
✅ Automatic pulse back-blow filter cleaning — no manual intervention
✅ Low noise operation — ideal for production environments
✅ Automatic level control — start/stop based on hopper fill level
✅ Simple, easy-to-clean design — quick disassembly for batch changeovers
How It Works
- Vacuum Generation: Compressed air supplied to the vacuum generator creates negative pressure, forming a vacuum airflow.
- Material Suction: Materials are sucked into the suction nozzle, forming a solid-gas flow that travels to the hopper.
- Filtration: The filter completely separates materials from air — clean air exhausts, materials collect in hopper.
- Discharge: When hopper is full, controller automatically cuts off air supply. Hopper door opens, materials fall into equipment hopper.
- Filter Cleaning: Compressed air automatically cleans the filter through the pulse back-blow valve.
- Auto-Restart: When set time is reached or level sensor sends feeding signal, feeder automatically restarts.

? Which Model Should You Choose?
QVC-3 (12L, 300-1500 kg/h): Ideal for small to medium production lines and as a scale-up from R&D. The 12L bin volume provides good buffer capacity while maintaining a manageable φ290×1047mm footprint.
For smaller applications: QVC-1 (lab/R&D) or QVC-2 (pilot scale).
For larger applications: QVC-4 or QVC-5 for medium to large production.
Vacuum Conveyor FAQs
Q1: How does QVC-3 compare to QVC-2 and QVC-4?
A: QVC-3 sits between QVC-2 and QVC-4 in the QVC series. QVC-2 offers 100-700 kg/h with 6L bin — ideal for pilot scale. QVC-3 offers 300-1500 kg/h with 12L bin — perfect for small to medium production. QVC-4 offers 600-3000 kg/h with 42L bin — for larger production lines. Choose based on your throughput requirements.
Q2: What is the gas consumption of QVC-3?
A: QVC-3 consumes 720 NL/min of compressed air at 0.4-0.6 MPa. Ensure your facility's compressed air system can supply this volume. For comparison, QVC-2 consumes 360 NL/min, and QVC-4 consumes 1440 NL/min.
Q3: Is QVC-3 suitable for tablet press feeding?
A: Yes. The QVC-3 is specifically designed for automatic feeding of tablet presses, capsule filling machines, dry granulators, packaging machines, crushers, and vibrating screens in small to medium production. Its 300-1500 kg/h range covers most tablet press feeding requirements.
Q4: Does the QVC-3 require a separate vacuum pump?
A: No. Like all QVC series models, the QVC-3 uses a built-in vacuum generator powered by compressed air (0.4-0.6 MPa). No mechanical vacuum pump needed — no moving parts, no oil, no maintenance, and very low noise.
Q5: How is the QVC-3 cleaned between batches?
A: The QVC-3 features a simple, easy-to-clean design with quick-release clamps for disassembly. The 12L bin volume is manageable for manual cleaning between batches. All contact parts can be easily accessed. For pharmaceutical applications requiring frequent changeovers, this design minimizes downtime.
