Industrial Vacuum Feeder | Powder & Granule Conveying for Capsule & Tablet Production
In modern pharmaceutical, nutraceutical, and food manufacturing, the link between bulk powder handling and high-speed processing machines — such as capsule filling machines and rotary tablet presses — is often the biggest bottleneck. Manual scooping or simple vacuum cleaners are slow, inconsistent, and risk cross‑contamination. Our industrial vacuum conveyor provides a sealed, automated transfer of powders and granules, directly feeding your capsule filler or tablet press. The result: throughput increases up to 300%, while dust and operator intervention are virtually eliminated.
01. Gentle & precise powder flow engineering
Whether you are feeding a capsule filling machine (dosator or tamping type) or a high‑speed rotary tablet press, consistent powder delivery is key to final product quality. Our vacuum conveyors are designed to maintain particle integrity and blend uniformity.
Segregation‑free transfer
Using a patented low‑velocity, dense‑phase vacuum principle, the conveyor moves materials gently, preventing particle segregation and preserving your formulation’s homogeneity — critical when feeding directly into capsule fillers or tablet presses.
On‑demand feeding synchronization
Equipped with a smart level sensor and PLC, the conveyor automatically starts/stops based on the machine’s hopper level. This guarantees a continuous, starvation‑free supply to your capsule filler or tablet press, maximizing OEE.
02. GMP / FDA compliant hygienic design
In regulated environments, the conveyor itself must become a cleanroom component. Our vacuum conveyors are built with pharmaceutical standards in mind, from materials to surface finish.
- 316L stainless steel construction: All product contact parts are mirror‑polished (Ra ≤ 0.8 µm), fully passivated, and certified for CIP/SIP. No dead corners, no bacterial traps.
- Quick‑connect tri‑clamp design: The entire conveying line, from pick‑up wand to discharge valve, can be dismantled in under 3 minutes without tools — essential for rapid changeover between different products.
- Anti‑static & dust‑tight filters: Multi‑layer polyester filters with antistatic treatment achieve 99.99% retention of particles >0.5 µm. Filter cleaning is automatic via reverse pulse-jet, maintaining suction power even with fine powders (lactose, API, herbs).
- ATEX / hazardous location options: For flammable powders like starch or sulphur, we offer conductive hoses, grounding continuity monitoring, and inert gas blanketing.
03. Measurable ROI: from manual labor to automated conveying
Installing a vacuum conveyor between your bulk bag/drum and your capsule filler or tablet press doesn’t just improve hygiene — it fundamentally changes your cost per tablet.
| Performance metric | Manual transfer (scoop / gravity) | Vacuum conveyor (automated) |
|---|---|---|
| Transfer rate (to capsule filler hopper) | ~50–100 kg/hour (operator dependent) | Up to 2,500 kg/hour (continuous, no fatigue) |
| Operator intervention | One operator full‑time | Zero operator during conveying – freed up for quality tasks |
| Cleaning time (product changeover) | 45–60 min (disassemble chutes, vacuum cleaner) | < 10 min (tool‑free disassembly, smooth surfaces) |
| Dust generation / cross‑contamination | High – airborne particles, spillage | Zero dust emission – fully closed system |
✔ Typical payback period: 4–8 months based on labour savings and yield increase alone. When feeding a rotary tablet press (e.g., 40 stations) or a high‑speed capsule filler (e.g., 2000 caps/min), the conveyor ensures the machine never starves, boosting overall equipment effectiveness by 15–25%.
⚙️ Seamlessly integrated with: capsule filling machines (all sizes), rotary tablet presses, mixers, blenders, and milling equipment. The vacuum conveyor becomes the silent productivity booster of your solid dosage line.
