The Vacuum Conveyor
A vacuum conveyor is a
dust-free , enclosed pipeline conveying system, designed to efficiently transport granular and powdery materials through the power of vacuum suction.
This advanced system generates an airflow within the pipeline by leveraging the pressure difference between the vacuum and ambient space, ensuring the rapid transit of powdered materials and seamlessly completing the conveying process.
Moreover, to cater to the unique demands of various industries, Shijiazhuang Rongxin Science and Technology Co., Ltd. offers customized vacuum conveying systems
integrated with cleaning and sterilization functions ,as well as
high-precision weighing capabilities.

- Features include independent reverse blowing for automatic filter cartridge cleaning;
- A simple structure ensuring easy operation and maintenance, with low noise levels;
- Cost-effective operation, adaptable to a wide range of applications;
- Enclosed, eco-friendly conveying system that ensures zero material leakage;
- Ability to utilize inert gas for safe handling of flammable and explosive materials;
- Equipped with an advanced material suction machine featuring cleaning functions, built-in cleaning balls, and components capable of CIP (Cleaning in Place) and SIP (Sterilization in Place);
- High-precision weighing components offer exceptional measurement accuracy of up to 0.5%.
