Lehmann developed and re-designed the technology of five roll refiners. Features such as the stainless steel body and the easy to remove feeding and discharge hoppers, are providing high quality production with high hygienic standards.

The feeding rolls can be adjusted by separate gear drives from the other rolls. Hydraulic pressure, cooling temperature and revolution speed as well as friction ratio can be adjusted easily. Optional, closed water loops to cool the rollers further improve the performance of the Lehmann five roll refiner. Flow rate capacity can reach up to 1,400 kg/hr. (3,000 lbs)
