What is a Shivvers Performance System?

Shivvers Performance Systems are a customizable package of high performance equipment engineered to work together to provide optimum performance for drying grain, using continuous Counter-Flow technology. Learn More

The Circu-Lator 2 Performance System is Shivvers’ signature system and offers you Continuous Counter-Flow Drying in bins up to 36’ in diameter.  The Shivvers Circu-Lator 2 Performance System is designed to dry up to 600 bushels per hour.  The tapered sweep augers remove an even layer of dried grain from the perforated floor to the center vertical where it is lifted to a transfer auger and on to your storage bins. 

All Circulator systems have a built in unloading auger which will unload the bin at high speed until the grain will no longer flow by gravity.  At this point the tapered sweep auger may be used to continue unloading.  The unloading auger and recirculating mechanism may be operated separately or together.  (1) Pushing jaw clutch into position operates the drive shaft and recirculating mechanism.  (2) Pushing the drive pin into position engages the unloading auger.

System Features

  • Re-Circulating machine with two tapered sweep augers
  • Surge capacity as large as the drying bin
  • Up to 14,400 bushels dried per day
  • Removal rates up to 600 bushels per hour
