  • What is small oil pressing plant?
  • The small oil pressing plant is a mini capacity oil extraction line which is fully adopted mechanical driven. It connects a series single oil processing equipment together to realize continuous oil extraction with easier operation and higher rate of oil yield for a greater efficiency.
  • What are the processing systems for oil pressing?
  • Generally there are usually two processing systems for oil pressing, one is Pre-pressing (combination with solvent extraction) and the other is Full-pressing (a true mechanical oil extraction process). Pre-pressing: Pre-pressing means extract oil first by mechanical screw press and then the pre-pressed cake is sent to the solvent extraction plant.
  • What percentage of oil is extracted by mechanical pressing?
  • Usually the mechanical pressing method provides yields of only 65-70% of the oil, and 80% is considered very good. Most large commercial operations use a mild pressing operation to extract 60 to 70% of the oil, while the remainder is solvent-extracted.
  • What is the difference between conventional oil extraction and mechanical pressing?
  • The traditional methods of oil extraction are exhaustive and have low efficacy, while conventional method of mechanical pressing is simple and involves low cost but considered as an inefficient method because of low oil recovery when compared with chemical extraction methods.
