Pressing Methods for Some Main Material
Soybeans: There are two ways of extruding soybean oil. They are hot pressing and cold pressing. (1) Hot Pressing: Soybeans – Selecting – Prepressing – Heating -- Pressing.
First select soybeans and remove foreign particles, then soften the material by breaking and adding water of 7- 8% and
then steam them to 115C, beans will be ready for pressing.
(2) Cold Pressing:Soybeans -- Selecting-- Pressing (in case of adequate water content).
Rape Seeds: Methods of hot pressing and cold pressing can also be used to extruding rapeseed oil. Hot pressing is recommended for the reason that oil extracted by the method of hot pressing is of higher quality and higher oil output rate.
(1) Hot Pressing: Rapeseeds – Selecting – Prepressing – Heating -- Pressing.
When using the method of hot pressing, to remove foreign particles by selection, then check water content as described above , in
case of too dry. Add 2.5-3% of water, normally two times extruding is enough.
(2) Cold Pressing: Rapeseeds -- Selecting-- Pressing (in case of adequate water content).
When using the method of cold pressing, pre-press and heat the seeds after selecting the material. Add 2-3% .of water and await
till look coffee color and temperature 110- 120C, then ready for pressing.
Groundnuts Kernel: Cold and hot pressing are both available, but hot pressing methods have better effect than cold pressing. Firstly crack or pre-press groundnut kernels then steam them for 1.5-2 hours, temperature should control about 120C and the water content control about 3%. Normal pressing starts at temperature of 85C or crack them firstly and at a pol. add 7- 8% of water. Look coffee color will be ready for pressing. If groundnuts with shells, you should remove the shell in advance by a peanut sheller.
