CHRONOS BFL SERIESHigh-precision open-mouth bagger for powders

Available in

Africa, Asia, Canada & USA, Europe, Latin America and Oceania

The BFL Series is an automatic open-mouth bagging equipment designed for quick and precise dosing of powders.

The patented powder bagging machine fills bags from bottom to top, reducing dust emission and keeping product aeration to a minimum, which is ideal when packing flour or other powdery products. The filling is done in two distinct steps, coarse and top-up fine filling, to reach target weights quickly and accurately.

The innovative dust-free bagging process is highly safe for operators. It is simple and intuitive to use and requires little maintenance. It offers a short payback period and 3X less product giveaway than any other technology on the market.
