ABSTRACT
Nowadays, single screw cold press and double screw cold press are the traditional way of cold press. Yield efficiency of single screw press is low, and its energy consumption is high. Yield efficiency of a double screw press has been greatly improved, but its energy consumption is also high. Transmission and squeeze of oil plants in both the single screw press and double screw press are done by friction. As is well known, friction generates heat, this is bound to cause large energy waste. More than 60% energy in the working process of the press machine is wasted because of friction according to the related experimental data. New centrifugal oil press is designed based on high efficiency and low energy consumption.
