The solvent extraction of vegetable oils like soybean oil dominates the oilseed industry as the most popular extraction method used around the world. Most large-scale solvent plants use hexane extraction to chemically separate oilseeds into liquid fat and solid protein—popular ingredients in the food industry and many other market sectors. Amid growing concern for natural,…
Although it only grows in a limited swath of sub-Saharan African parklands, the wild shea tree supplies the entire world with enough shea nuts to meet the growing demand for both shea oil and shea butter. African civilizations have been processing shea nuts by hand for centuries, using tedious traditional methods of shea butter extraction…
One of the earliest domesticated crops in human history, flax has found a wide range of applications through the millennia. As a valuable source of food, animal feed, fiber, flooring, and many other uses, it’s no wonder why the Latin name of this ancient herb translates as “most useful.” Every part of the plant is…
Ever since inventing the first continuous mechanical screw press in 1900, Anderson International has continued innovating new and improved solutions for seed oil extraction. Their monumental press invention sparked a series of other innovations—including the original Expander-Extruder-Cooker (EEC), which led to the development of the Solvex Expander, now used widely to prepare oilseeds for solvent…
As the demand for organic food increases, farmers are reevaluating how they produce (and feed) livestock to meet these demands. Although solvent extraction is commonly used for high-volume oil production, the meal left over from this process can’t be used as organic animal feed because of the hazardous chemicals involved. Soybean meal generated from chemical-free…
Since Anderson International invented the first continuous mechanical screw press in 1900, the company has continued improving and innovating its extraction equipment for different applications. After an accidental modification of the Expeller led to the creation of Expanders in the 1950s, this value-added machine made a monumental impact on processing efficiencies across various industries. Here’s…
Conditioning oilseeds, or cooking them before extraction, is one of an oil mill’s most important processing steps. But cooking wasn’t always a convenient process, especially in the past when hydraulic batch presses were the predominant extraction equipment in the industry. After Anderson developed the continuous process of crushing oilseeds in the early 1900s, the company…
When Ali Baba commanded, “Open Sesame,” in the famous Arabian folk tale, a sealed cave full of treasure magically opened before him. Likewise, processors today can unlock a veritable treasure trove of profits by tapping into the potential of this tiny ancient seed to extract high-quality sesame seed oil. One of the oldest cultivated oilseed…
When Valerius D. Anderson filed a patent for his mechanical screw press in April 1900, during the Industrial Revolution, he planted the seeds for a groundbreaking invention that would revolutionize the industry. At that time, a batch hydraulic press was the only way to mechanically extract liquid from solid material. It could take hours to…
