  Shivvers® Continuous Flow Grain Drying  

 

 
Shivvers®

Shivvers®

Shivvers® Incorporated, began in 1968 when Charles Shivvers developed the patented tapered sweep auger, the basis for the first commercially successful counterflow drying system. Shivvers® has designed, manufactured, and marketed in-bin continuous flow drying systems and related products like fans, floors, spreaders, and controls for over thirty years. In the early 80's, Shivvers® was the first grain drying company in the industry to design, patent and market computer controls for grain dryers. Today Shivvers® continues to lead the industry with the best, most accurate moisture control on the market, the CompuDry Command Center.

Shivvers®' Circu-Lator I & II are complete, totally automated grain handling and drying systems. Wet grain from the field is unloaded directly into the drying bin. This grain is dried and automatically transferred to storage bins which may be located over one hundred feet away.

The Circulator System can be easily expanded, fitting the needs of operations handling from 6,000 to 300,000 bushels per year.

No other drying system can match this combination of built-in surge capacity, totally automatic drying, and push-button grain handling.

Features:

Unloads

The Circulator has 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.

Simple Operation

Start your fan, heater and Circulator Fill the bin to any level with wet grain. The Circu-Trol (control panel) automatically starts the Circulator when the bottom layer of grain becomes dry. The Tapered Sweep Auger rotates around the bin removing dry grain in a thin even layer.

This dry grain is pulled to bin center where it is elevated to the top by the Center Vertical Auger, and transferred to the storage bin for cooling by the Continuous Flow Auger. The Circu-Trol stops the Tapered Sweep when all the dry grain has been removed, automatically starting it again when necessary.

No Babysitting

The drying process continues around the clock automatically day and night. Moisture checks three times a day are all that are required. These may be taken from the ground, using the Grain Sampling Valve. Circulator owners operate the system 24 hours a day, without babysitting.

Recirculating Batch Dryer

Shivvers®

Shivvers®

The Continuous Flow Auger is turned off when the adjacent storage bins are filled, and the Circulator becomes a Recirculating Batch Dryer. In recirculation, the dry grain is removed from the bin floor, elevated up the Center Vertical Auger and respread on top by the Recirculation Spreader.

The grain is normally dried in two passes when recirculating. In the first pass the Circu-Trol is adjusted to recirculate the grain when it reaches 20% moisture content. Wet grain is then added to the bin, drying as it is filled.

After the bin becomes full, the Circu-Trol is reset to dry to the desired moisture content in the final pass. When the bin is c completely dried, the burner is turned off and the grain is cooled by the drying fan.

The basic Circulator may be initially installed without the Continuous Flow Auger and operated alone as a Recirculating Batch Dryer. The Continuous Flow Auger can be added later, converting the system in a Continuous Flow Dryer.

Surge Capacity

The Circulator System has wet holding capacity as large as the drying bin. Wet grain may be added to the drying bin at any time - as fast as you harvest. This large surge capacity lets you harvest rapidly when the going is good - and stretches out the drying load when weather and other problems slow you down.
