  • How oil seeds are compressed during the process of mechanical expression?
  • During the process of mechanical expression, the oil seeds are compressed in various types of compression devices/equipment. Expression is the process of mechanically pressing liquid out of liquid containing solids. Screw press, roll presses, collapsible plate are some examples of wide range of equipment used for expression of liquid.
  • What is the mechanical expression of oil from melon seeds?
  • Investigations were conducted on the mechanical expression of oil from melon seeds ( Citrullus vulgaris) in a laboratory press. The processing variables were particle size, moisture content, heating temperature and heating time. Physical properties such as colour, specific gravity, refractive index and viscosity were determined.
  • Does a screw press machine affect oil yield of N sativa seeds?
  • Abstract: The effects of physical parameters of a screw press machine on oil yield of N. sativa seeds were studied using a KOMET Screw Oil Expeller. Different nozzle size (6, 10, and 12 mm), extraction speed (21, 54, 65 and 98 rpm) and diameter of shaft screw (8 and 11 mm) were applied in this study.
  • Can a quadratic model predict the oil expression process for moringa seeds?
  • In terms of higher coefficient of determination ( R2) and lower standard deviation values, the quadratic model was finally chosen ahead of the linear model to predict the oil expression process for moringa seeds ( Table 2 ).
  • Is mechanical expression a better option than a solvent process?
  • Mechanical expression or mechanical pressing is, however, preferable due to the fact it is economical compared with the solvent process. At the laboratory scale, many authors have highlighted the effect of operating parameters and raw material on process performance (oil yield and press capacity).
  • How does seed production affect oil extraction process?
  • The increase in the quantity of seed being slightly lower than the increase in oil production, it demonstrates an improvement of oil extraction processes. Generally, the oil extraction is based on two main steps: pressing (solid–liquid expression) and solvent extraction.
