Products Description
Need continuous, high-precision dosing of powders into mixers or reactors?
Guanjiang's Vacuum Conveyor for Mixer (Loss-in-Weight Feeder) combines dust-free vacuum suction with real-time gravimetric weighing technology. The system delivers continuous, accurate dosing by compensating for material density changes in real time. Designed specifically for loading 2D, 3D, and V-type mixers, it ensures zero contamination, minimal error, and fully automated feeding cycles — ideal for pharmaceutical and food processing.
Key Performance Advantages
Loss-in-weight technology compensates for material density changes in real time. Gravimetric sensors detect flow variations instantly, adjusting feed speed to ensure consistent accuracy — regardless of material flowability.
Operates under negative pressure to prevent powder leakage. Maintains a clean workspace, protects operator health, and prevents cross-contamination — essential for GMP environments.
Easily connects with existing production lines — mixers, reactors, blenders, and packaging systems. Enables fully automated feeding cycles with real-time data logging and remote control.
Manufactured from Stainless Steel 304/316L with mirror-polished surfaces. Rounded corners and seamless welds eliminate crevices — meets stringent food and pharmaceutical GMP standards.

Dosing & Conveying Insights
Q1: How does the loss-in-weight system handle different material flowabilities?
A: Our gravimetric sensors detect flow changes instantly. The control system adjusts feeding speed in real time to maintain accuracy — whether the material is free-flowing (granules) or prone to bridging (fine powders, sticky materials). No recalibration needed for different materials.
Q2: Can this vacuum conveyor be integrated with my existing mixer or reactor?
A: Yes. The system is specifically designed for loading 2D, 3D, and V-type mixers, as well as reactors and blenders. The PLC interface allows seamless integration with your existing production line controls. We provide custom adapter flanges to match your equipment.
Q3: What is the dosing accuracy of this system?
A: The loss-in-weight feeder typically achieves accuracy of ±0.1% to ±0.5% of setpoint, depending on material characteristics and feed rate. This makes it suitable for high-value ingredients, APIs, and precise recipe formulations.
Q4: How is the system cleaned between batches?
A: The hygienic design with mirror-polished surfaces and smooth welds allows for easy manual cleaning. For frequent changeovers, we offer an optional CIP (Clean-in-Place) system with spray balls that clean the vacuum hopper, conveying line, and receiver automatically.
