Whether floured fish filets, calamari, sweet wine gum, or quark balls: Our preduster allows for ideal processing of fine coating materials like fine-grained flour, spices, powder, and sugar. Two systems of belts guarantee complete and even coating. A lower belt runs the product through a material bed while the upper belt generates the required sprinkling action from above onto the product to be coated. That way, your products will get the coating that you precisely intended through adjustable pressing, vibration, and blower systems.


Our preduster coats products evenly with fine flour, bread crumbs, powder, spices, and sugarIt applies an absolutely complete and even coating following entirely your ideas.

The preduster PRO Vario-Flip

Our preduster Vario-Flip combines two coating styles in just one system: as a level-flow variant, the products are floured, sugared or seasoned in the classic way. Via the innovative Vario-Flip variant, the product inside the system performs four successive flips of 180° each and absorbs more coating material with each flip, for a rough, natural and, above all, handmade coating result.

  • Sensitive molded products such as chicken tenders or fish sticks, as well as irregularly shaped products such as chicken parts, can be fully coated in homemade style
  • tool-free changeover between both variants without stopping production
  • tool-free adjustment of the flip height without stopping production
  • perfectly aligned with the growing demand for homemade style products
  • in contrast to drum breaders, the Vario-Flip offers fragile molded products an appropriate finish as well
