  • Can soybeans be crushed by prepress solvent extraction?
  • Only in one instance has the author observed soybeans being crushed by prepress solvent extraction, and that plant normally crushed sunflower seed¡ªthe amount of oil in soybeans simply does not warrant this type of processing that is used for higher oil-containing seeds such as sunflower, peanuts, safflower, and canola.
  • Do soybeans need to be prepressed?
  • Only when soybeans are processed in plants designed for other oilseeds (e.g., cottonseed, sunflower seed, etc.), which must be prepressed, are soybeans subjected to prepress solvent extraction. Soybeans do not contain sufficient oil to require or justify prepressing and are rarely, if ever, prepress solvent extracted.
  • What is soybean processing?
  • Soybean processing can be broken down into two (if screw pressing) or three (if solvent extracting) major areas: preparation (cleaning, dehulling, flaking, expanding), extraction (screw pressing, solvent extraction), and oil/meal finishing (oil and meal desolventizing, oil cooling and filtering, and meal toasting, drying, cooling and grinding).
  • How many tons a day can a soybean processing plant process?
  • Today’s new soybean processing plants using direct solvent extraction need to be capable of processing at least 2,700 metric tons per day (3,000 tons/day) to be economically viable in the United States, representing an investment of over $75 million.
