Circu-Lator 1

The original unit with unload rates up to 7200 bushels per day.

The Circu-Lator 1 is the original unit and is ideal for operations and bins that need capacity of up to 7,200 bushels per day. This unit became the start for development of our high capacity machines. This machine can be used as a continuous-flow system to transfer grain to nearby bins or a recirculating system in stand-alone bins.  If used as a continuous-flow system, the tapered sweep auger moves the grain to the bin’s center and up the center vertical auger to an optional transfer auger for delivery to a storage bin.  During recirculation, the sweep auger removes the dried grain in even layers to the center of the bin where it travels up the center vertical auger as is deposited on the top of your grain.  

The Circu-Lator is engineered for high capacity and durable operation.  A system that combines the reliability of extra tough rugged construction with easy operation, built to keep pace with harvest.  It provides totally automatic in-bin continuous flow drying.  The drying zone of a Circu-Lator is maintained at the bottom of the grain bin.  Therefore, heated air blown into the bin at floor level must travel upward through wet grain to escape.  As a result, the hot air becomes fully moisture saturated before it's exhausted-eliminating energy waste.

Machine Components

The Circu-Lator 1 is driven by one motor located outside the bin. Power is transmitted to the bin center by a unique “shaft within a shaft” arrangement. A 1” diameter solid steel drive shaft rotates inside the larger power shaft of the unloading auger, and is driven without turning the unloading auger. The drive shaft powers the gearbox that turns the Tapered Sweep Auger and Center Vertical Auger. The unloading auger is independent of the recirculating mechanism and may be operated without the Circu-Lator.

6" Center Vertical

The center vertical auger rotates gently elevating the grain up the center of the bin.  A 1/2" cushion space between the heavy flighting and tube prevents grain damage.  When the continuous flow auger is in operation the grain is pulled away to storage.  If it is not in operation, the grain is elevated to the recirculation spreader and respread evenly on top.

Gearbox

Rugged gearboxes are built for long years of durable service.  They are packed with grease, have oversize 1 1/4" stressproof shafts, hardened steel gears and tapered thrust bearings.  They are protected by three seals on every shaft opening and zerks are provided for directly lubricating each bearing.  The weight of the center vertical auger is borne by a rugged cast iron spider wheel which transmits the load to thrust bearings.  

8" Horizontal Unload Auger

The drying bin can be unloaded independently of the Circu-Lator through the built-in unloading system.  The horizontal discharge unit may be converted to vertical discharge with the addition of an 'add-on' vertical unloader.

Tapered Sweep Auger

The tapered sweep auger removes thin, even layers of of dry grain as it travels around the bin. It's patented taper is the secret of the Circu-Lators uncanny moisture control; allowing it to remove only the dry grain which lays just above the drying floor.  The auger itself is constructed of a 1 1/4" diameter solid alloy steel shaft with 1/4" flighting.  The notched cast iron wheel of the tapered sweep auger travels on a wear track as it rotates around the bin, remaining on the floor at all times.
