At Powtech Technopharm 2025, Europe’s international trade fair for powder, solid and liquid processing technologies, PAYPER presented its latest innovation: the bottom-up filling system, developed to ensure clean, accurate and dust-free bag filling.
With this addition, PAYPER expands its portfolio of advanced solutions for bagging powdery products, reaffirming its commitment to innovation, efficiency, and industrial safety.
The new bottom-up filling system is based on a vertical screw conveyor equipped with an adjustable outlet opening device and a mechanism that lifts the bag and then lowers it gradually during the filling process. This design allows a minimum distance to be maintained between the dosing point and the product, significantly reducing the free fall of the material. As a result, dust dispersion is prevented and the quality of the working environment is improved, while product losses are minimized.
The main advantages of the system include:
- Minimal dust generation, contributing to a cleaner and safer working environment.
- Reduced ATEX risk by minimizing the generation of dust clouds.
- Less product capture by the suction system, resulting in savings and optimization of resources.
- Prevents product fluidization, preserving its original properties and behavior during bagging.
Thanks to these characteristics, the bottom-up filling system is especially recommended for high-value powdery products or those that require high hygiene standards.
With more than 50 years of experience in the design and manufacture of bagging and palletizing equipment, PAYPER continues to consolidate its position as one of the world’s leading manufacturers of state-of-the-art bagging lines for solids.
