Nanjing Huozao Machinery Technology Co., Ltd. is one of the leading manufacturers and suppliers of powder vacuum feeder in China. With abundant experience, we are committed to providing high quality equipment made in China with competitive price. Welcome to wholesale customized powder vacuum feeder from our factory.
Features
Fully Closed Conveying Structure
Material moves entirely within sealed pipes and hopper. No open exposure occurs during feeding and transferring. This structure controls on-site dust, avoids cross-contamination and reduces material waste in daily production.
Automatic Cyclic Feeding
Programmable operation replaces repetitive manual feeding. The machine can work continuously with mixers and packaging equipment to form a streamlined production setup, lowering on-site labor dependence.
Gentle Airflow Conveyance
No screw blade or rigid stirring parts exist in the conveying path. Airflow carries powder steadily. This mechanical design minimizes material squeezing and friction, reducing powder segregation and protecting original material properties.
Flexible On-Site Installation
Compact body structure saves floor space. Equipped with standard hoses and quick connectors, the machine can adapt to different equipment layouts. Operators can adjust pipeline length and connection position according to actual workshop conditions.
Easy Daily Maintenance
The Powder Vacuum Feeder adopts a simplified mechanical layout. Routine work mainly covers hopper cleaning, filter inspection or replacement, and regular valve and pipeline checks. No complex maintenance procedures are required for normal operation.

Material Matching and Model Selection
Fine Powder Handling
Fine and ultra-fine powder requires high-precision filter elements. PTFE-coated filters are commonly configured to prevent fine dust penetration. Venturi suction structure can be installed to stabilize suction airflow for lightweight powder.
Granular Material Handling
Pipe diameter and discharge opening size need to match particle dimension. Proper structural sizing lowers blocking probability during continuous conveying.
Poor-Flowing Materials
Materials prone to bridging and wall sticking can be matched with hopper vibrators. Polished inner surface or anti-stick treatment helps ensure smooth material discharging and stable cycle operation.
High-Temperature Materials
High-temperature working conditions require temperature-resistant filter elements and sealing parts. All material-contact components must adapt to actual processing temperature.
Hygienic Production Requirements
Food and pharmaceutical processing adopt 304 or 316L stainless steel contact parts and sanitary quick-release structures. The whole machine supports repeated cleaning to meet common hygiene standards.
Explosion-Proof Configuration
For flammable powder and explosive dust environments, the machine can be fitted with explosion-proof electrical parts, static grounding and nitrogen protection devices. Final safety configuration follows on-site hazard classification and local industry specifications.
Compatibility with Mixing Equipment
This vacuum feeder supports direct connection with multiple mixer types, including V-type mixers, 3D mixers, 2D mixers, double cone mixers and ribbon mixers. It delivers automatic material feeding from storage tanks to mixing equipment, realizing closed-loop powder production and reducing manual operation errors.
Applications
This equipment is widely used for automatic feeding of dry powder and granular materials in multiple industries, covering pharmaceutical excipients, food seasonings and nutritional powders, chemical additives, fine chemical raw materials, new ceramic materials and feed ingredients.
It is a practical auxiliary device for production lines that require dust control, closed processing and stable automated feeding.
