A Comprehensive Guide to Essential Oil Extraction

  • 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.
  • How long does it take to extract oil from flaking seeds?
  • Oil from the cracked or flaked seeds should be extracted as quickly as possible (within 24 hours) to minimize meal and oil quality deterioration. Flaking mills, which can process 300 to 500 tons of seeds per day, are available. Buhler and CPM Roskamp are the major suppliers of flaking mills.
  • 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.
  • Why do oil seeds need to be cleaned?
  • Oilseeds need to be cleaned to remove plant stems, sticks, leaves and foreign material before storage. Such material may decompose and cause heating in stored seed mass diminishing oil and meal quality. Foreign materials in seeds are typically separated out by a combination of rotating or vibrating coarse screens, reels and aspiration.
  • How long can oilseeds be stored?
  • Whole, intact, low-moisture oilseeds (about 8-10 percent moisture) may be stored for an extended time under suitable conditions. Deterioration of oilseeds is accompanied by respiration or carbon dioxide evolution and heat generation by oxidation reactions.
  • Are oilseeds a good feedstock for biodiesel?
  • A wide range of oilseeds and other oil-producing plants are high-quality feedstocks for biodiesel. Oilseed processing expands the use of crops such as sunflowers and brings value to grape seeds, which are usually waste products. Most oil processing in the United States is done on a large industrial scale.
