Soy crushing (presning af sojabønner)
|
Switzerland
1990.
|
Soy beans can be crushed industrially to
produce soy cake and soy oil
Process description
The present data
refer to soy crushing in Switzerland
in early nineties where
the production processes
are following:
1)
Soybeans are received from farms, 2) the soybeans are pulverized, 3) the pulverised
beans are pressed and soy oil and soy meal are separated 4) oil
remaining
in soy meal is extracted with hexane, 5) soy meal is toasted, granulated, cooled
and stored for
distribution 6) soy oil from hexane extraction
is gained by vacuumdestillation and mixed with oil from obtained from
pressing, 7) soy oil is rafinated and stored for distribution.
