  • How are seeds prepared for oil extraction?
  • Unit operations for preparation of seeds for oil extraction vary slightly depending on the physical properties and oil content (Figure 1). However, most oilseeds go through the process of cleaning, drying dehulling, size reduction, flaking cooking and tempering.
  • Can you use a grain dryer for oilseeds?
  • Large, vertical, open-flame grain dryers can be used for oilseeds as well. These dryers have multiple columns of oilseeds which slowly migrate downward. The upper portion of the column is used for drying and lower section is for cooling. The amount of hull on oilseeds varies significantly.
  • Why do oilseeds need to be separated before oil extraction?
  • Most oilseeds need to be separated from their outer husk or shell prior to oil extraction. Dehulling also is referred to as shelling or decorticating. Dehulling increases oil production efficiency, capacity of the extraction equipment and reduces wear in the expeller as the husks are abrasive.
  • How are cracked & dehulled soybeans conditioned / tempered?
  • Cracked and dehulled soybeans are conditioned/tempered by increasing the temperature to 149 degrees Fahrenheit and adjusting the moisture by using live steam. Conditioning is done in rotating drums with an internal steam coil. Tempering improves flaking performance and extraction efficiency.
  • How did the first cottonseed oil mill work?
  • The first cottonseed oil mill constructed in the United States in the 1920s utilized a hydraulic press. Seeds in filter bags were manually loaded into perforated, horizontal boxes between the head block and the ram of the press. Boxes were pressed together by applying hydraulic pressure on the ram.
  • Why do oilseeds need a low moisture content?
  • The moisture content of oilseeds often needs to be reduced to minimize degradation in storage and to improve the effectiveness of downstream processing. For example, soybeans are often received at 13 percent moisture and need to be dried to 10 percent moisture to facilitate efficient hull removal.
