The OMLH1 BF SERIES open-mouth bagging systems are specially designed for the hygienic bagging of powdery bulk materials such as milk powder / whey powder / lactose powders, baby food, chemicals, pharmaceuticals etc.  Our patented bottom-up filling technology features high filling accuracies, an open or closed bag-top transport unit, quick and simple cleaning, fast change-over times and minimised dust emission.

After the bag placement, the filling spout moves the bag down the vertical filling screw during the filling cycle. A minimum distance between the filling point of the vertical filling screw and the product in the bag is maintained to significantly minimise the dust emission and reduce the product aeration. The vertical screw is frequency / servo control driven, allowing all powdery products to be filled hygienically, accurately and quickly. 

The innovative bottom-up bagging system combined with our modular approach provides you with the opportunity to create a bagging system for your current and future needs.  The OMLH1 BF SERIES is available in single and single with post dosing configuration with outputs up to 400 bags per hour. The series is equipped with gross weighing systems for precise filling results.
