  • What is vegetable oil processing from soybeans or sunflower seeds?
  • Vegetable oil processing from soybeans or sunflower seeds is low-margin, bulk production with a clear dependency on maximum uptime and optimized operating expenses. Thanks to the diligent assistance o... The Tampieri family has been producing grapeseed oil for more than 90 years.
  • 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.
  • 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.
  • 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 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.
  • Does a cracking mill reduce seed size?
  • Canola, rapeseed and corn germ do not require size reduction as they are already sufficiently small. Cracking mills are used for seed size reduction. A cracking mill consists of two sets of cylindrical corrugated rolls in series. The rolls rotate at differential speeds to break apart seed cells containing oil.
