Mechanical Continuous Oil Expression from Oilseeds: A Review
The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h−1 to 150 t day−1). At the laboratory scale, many authors have highlighted the effect of operating parameters
This work studies oil seeds mechanical expression in a screw press. For this purpose, a pilot-scale screw press (0–40 kg/h) was instrumented by installing sixteen pressure sensors and three temperature probes throughout the screw. Canola (Brassica napus L) and flax (Linum usitatissimum) seeds were used for investigation. The impact of the

Jan 01, 1990· The initial increase in oil yield obtained with increase in moisture loss during heating may be attributed to the coagulation of protein in the oilseed samples thus creating bigger voids for freer oil flow during expression. For oilseeds with high-protein content such as melon seeds (28.4% protein), protein coagulation due to heat treatment may

Calculus Elements for Mechanical Presses in Oil Industry
A significant influence on oil yield has the postheating moisture content of some oilseeds (Ajibola et al., 1993). Effects of oilseeds heat treatment are: rupture of the oil bearing cells of the seed, coagulate the protein in the meal, adjust the moisture level of the meal to optimum level for oil expression.
Continuous screw presses have been used in two ways in oilseed extraction for over 80 years. The first is full-press operation, where the oilseed, after heat condi-tioning, is pressed one or more times through the same press or through several presses installed in series. In these cases, the screw press is the sole means of extraction.
