Sanitary Dryers

The Enhanaced Sanitary Dryer was engineered with a well-defined focus: increasing sanitation to the highest level possible

After thousands of hours of engineering and testing, Wenger is proud to offer the industry standard for sanitary, horizontal dryer design.  Features include:


  • Elimination of internal flat surfaces where practical, including no internal horizontal surfaces larger than 5 x 5 mm
  • Addition of insulated doors below process air fans
  • Isolation floor separates wet incoming product from finish product
  • Minimum 30° slope on all internal ledges
  • Improved geometry between conveyor endplates and stationary flashing
  • Modification of structural members
  • Elimination of crevices that could collect fines and pathogens
  • Increased access below upper and lower product conveyors
  • Access panels at turnaround area of conveyors
  • A direct-drive spout spreader that adjusts “on the fly”

Less Material, Easier Cleaning


The Enhanced Sanitary Dryer has eliminated the majority of surfaces where material can collect.


  • Optimized conveyor end plates that provide more efficient airflow and less product spillage
  • New chain and rail area slides that eliminate fines/kibble build-up and improve fines removal
  • New conveyor side seals that prevent product spillage yet can be removed for cleaning
  • Enhanced plenum fines augers that run the full length of the dryer for advanced fines removal
  • Floor fines drags that continually clean dryer floors with 99% efficiency
  • Polyester air filters on dryer and cooler makeup air openings filter room air as it enters the system
  • Advanced Control Options

    Energy Control System

    Minimize energy costs by 5% to 10% by optimizing the saturation of dryer process air. Energy control uses the internal process air to its full moisture removing potential before exhausting out of the dryer — optimizing energy efficiency.


    Moisture & Energy Control System

    Minimize moisture variation in the final product via data collected from the extruder APM. This system ignores moisture values input during unstable running conditions and can predict final moistures of less than =/-0.25 percent of a set point.
