High-Efficiency Dust-Free Continuous Powder Conveying Solution
JR Machinery Continuous Vacuum Feeding Machine is an advanced negative pressure conveying system designed for continuous and stable transport of dry powder materials. It solves the problems of traditional intermittent feeding systems such as low efficiency, dust leakage, and unstable feeding.
With fully enclosed conveying technology, intelligent PLC control, and modular design, it is widely used in automated production lines across multiple industries.
Product Introduction
The continuous vacuum feeding machine integrates vacuum generation, filtration separation, and intelligent control systems to achieve uninterrupted material suction, conveying, and discharge.
Compared with traditional batch-type vacuum feeders, this system supports continuous feeding without interruption, significantly improving production efficiency and stability.
Key construction materials include 304/316L stainless steel, ensuring corrosion and wear resistance and compliance with GMP and ISO standards.
Working Principle of Continuous Vacuum Feeding Machine
The system operates based on negative pressure conveying technology:
- Vacuum generator creates a high negative pressure environment inside the system
- Material is sucked into the pipeline through suction nozzles
- Air and powder are separated by a high-efficiency filtration system
- Material is continuously transported to the discharge point
- Pulse backblowing system cleans filters automatically to prevent clogging
The PLC intelligent control system synchronizes vacuum pressure, feeding speed, and discharge volume to ensure stable continuous operation.
Product Advantages
- 24-Hour Continuous Operation
- Supports uninterrupted feeding for large-scale production lines with capacity up to 1000–8000 kg/h.
