Products Description
Need a maintenance-free vacuum conveyor for pilot scale or small-batch production?
Guanjiang's QVC-2 Vacuum Powder Conveyor uses a compressed air-driven vacuum generator (no mechanical vacuum pump) — offering a simple, compact, maintenance-free solution with 100-700 kg/h capacity and a 6L bin volume. With a φ213×628mm footprint, it's the ideal step up from lab-scale QVC-1 for pilot plants, small-batch pharmaceutical production, and R&D scale-up. Features automatic pulse back-blow filter cleaning, GMP compliance, and elimination of material static electricity.
Key Advantages of QVC-2
Delivers 100-700 kg/h throughput with a 6L bin volume. Perfect for pilot plants, small-batch production, and R&D scale-up.
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 lab and pilot 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-2 (6L, 100-700 kg/h): Ideal for pilot plants, small-batch production, and R&D scale-up. The 6L bin volume provides good buffer capacity for pilot-scale operations while maintaining a compact φ213×628mm footprint.
For smaller applications: QVC-1 for lab/R&D (50-300 kg/h).
For larger applications: QVC-3 (300-1500 kg/h), QVC-4 (600-3000 kg/h), or QVC-5 (900-6000 kg/h).
Vacuum Conveyor FAQs
Q1: How does QVC-2 compare to QVC-1 and QVC-3?
A: QVC-2 sits between QVC-1 and QVC-3 in the QVC series. QVC-1 offers 50-300 kg/h with 1.1L bin — ideal for lab/R&D. QVC-2 offers 100-700 kg/h with 6L bin — perfect for pilot plants and small-batch production. QVC-3 offers 300-1500 kg/h with 12L bin — for small to medium production. Choose based on your throughput requirements.
Q2: What is the gas consumption of QVC-2?
A: QVC-2 consumes 360 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-1 consumes 180 NL/min, and QVC-3 consumes 720 NL/min.
Q3: Is QVC-2 suitable for tablet press feeding in pilot plants?
A: Yes. The QVC-2 is specifically designed for automatic feeding of tablet presses, capsule filling machines, dry granulators, packaging machines, crushers, and vibrating screens in pilot plant and small-batch settings. Its 100-700 kg/h range covers most pilot-scale feeding requirements.
Q4: Does the QVC-2 require a separate vacuum pump?
A: No. Like all QVC series models, the QVC-2 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-2 cleaned between batches?
A: The QVC-2 features a simple, easy-to-clean design with quick-release clamps for disassembly. The 6L bin volume is easily manageable for manual cleaning between batches in pilot plant operations. All contact parts can be quickly accessed. For pharmaceutical applications requiring frequent changeovers, this design minimizes downtime.
