hydraulic cause it is quicker and it dosent make a difference
any way。 But it has a relative small productivity and need great

Any oil press has its own application scope. If this oil press

Hydraulic is more suitable for pressing high oil contant oilseeds
likle sesame, alomnd, etc. So in this case, it is a good oil press
too.
