FAQ

  • QIs soybean meal a profitable oil extruding process?
    AThough the oil expelling process is used to produce oil, the soybean meal is actually the driving force for the whole production system. From Figure 8 a, the increasing economic and markets can be also impacted. The extruding-expelling process has positive gross and net profits, indicating this process was profitable.
  • QHow is soybean oil extracted?
    AYet, some operators overlook a critical step in their soybean oil extraction process to save significant time and energy. In solvent extraction, flaked soybeans are washed with hot solvent, typically hexane, to separate the solids from the fats. Multiple washes dissolve the oil and carry it away.
  • QWhat oils can be processed?
    AAll kinds of seed crude oil. For example common oils: soybean, peanut, sunflower, rapeseed, palm fruit, coconut, rice bran, corn germ, cottonseed, etc.
  • QWhich method of oil removal is used in soybean processing?
    AMechanical pressing and solvent extraction are the two primary methods of oil removal used in soybean processing. The mechanical process, with hydraulic pressing and continuous screw pressing techniques, was used before the development of solvent extraction [ 9 ].
  • QWhat is solvent extraction of soybean oil?
    AThe solvent extraction of soybean oil has become the most popular extraction method used across the globe. With a distinct advantage over traditional mechanical pressing, solvent extraction yields higher oil recovery and greater efficiency, leaving less than 1% residual oil in the meal.
  • QHow hexane is extracted from crushed soybean?
    AThe solubility of hexane and oil is the principle for the solvent extraction to extract oil from crushed soybean, and the desolvenization is applied to recover free oil and soybean meal. Further degumming and refining processes are needed for both expelling and hexane extraction to remove phospholipids and other impurities. Fig. 1.
  • QCan two-stage extruding-expelling process improve soybean oil yield?
    ATo examine the viability of this improved two-stage extruding-expelling process, techno-economic analysis was performed by using SuperPro Designer for simulation of the soybean extruding-expelling process. Soybean oil yield increases to over 70% compared to the conventional single-step expelling process with 60%.
