• What is cold press oil processing?
  • Cold press oil processing is a method where heat exposure is minimized to offer the highest recovery of oil in a single pass. In oilseed processing, the primary goal is to extract as much oil as possible from the seed while consuming as little energy as possible. The result is two end products: oil and the leftover solids, traditionally called meal.
  • What is oil processing & how does it work?
  • The primary goal of oilseed processing is to extract as much oil as possible from the seed while consuming as little energy as possible. The result: two end products, oil and the leftover solids traditionally called meal. The two most common methods for separating the oil from the oilseed are chemical extraction and mechanical extraction.
  • What is industrial pressing of oilseeds?
  • Industrial pressing of oilseeds is realized using continuous screw presses. The presses are fed with crude or pre-treated seeds. Types of pre-treatments (thermal pre-treatment, size reduction, mechanical sieving, etc.) differ for various seed species (Carr 1997). Each type of seed pre-treatment provides its own advantages.
  • What happens during screw expeller processing of palm kernel seeds?
  • Heat transfer between the pressing chamber and the oil and oilcake streams during screw expeller processing of palm kernel seeds. Journal of Food Engineering, 31 (1), 1¨C7. Omobuwajo, T. O., Ige, M. T., & Ajayi, A. O. (1998). Theoretical prediction of extrusion pressure and oil flow rate during screw expeller processing of palm kernel seeds.
  • What is oil extraction process?
  • Generally, the oil extraction is based on two main steps: pressing (solid¨Cliquid expression) and solvent extraction. Mechanical and thermal pre-treatments preceded these processes and contribute to enhance their performances. Depending on the seed species, the oil recovery processes can vary.
  • How is temperature selected in hexane extraction process?
  • Hence, temperature selection is based on type of oil and required specifications of the final product. There are three major steps in traditional solvent extraction (Figure 1): oil extraction, meal and oil desolventizing, and meal toasting.
