The Vacuum Conveyor
A vacuum conveyor is a revolutionary solution for material transportation.
It operates in a dust-free manner, utilizing a closed pipeline system to transport granular and powdery materials with exceptional efficiency through vacuum suction.
By leveraging the pressure differential between the vacuum and the ambient space, it generates a powerful airflow within the conveying pipeline, ensuring rapid and effective movement of powdered materials to complete the conveying process.
To cater to the unique demands of various industries, Shijiazhuang Rongxin Science and Technology Co., Ltd offers advanced vacuum conveying systems
featuring integrated cleaning and sterilization functions,in addition to
sophisticated high-precision weighing capabilities.

- The system boasts independent reverse blowing for automatic filter cartridge cleaning;
- a simple structure for easy operation and maintenance, along with low noise levels;
- low operating costs, making it highly versatile and widely applicable;
- an enclosed and environmentally friendly design to prevent material leakage;
- the capability to use inert gas for material protection, ensuring safe transport of flammable and explosive substances;
- a material suction machine equipped with built-in cleaning balls and components, enabling cleaning in place (CIP) and sterilization in place (SIP);
- and high-precision weighing components that deliver measurement accuracy of up to 0.5%.
