Abstract: On the basis of the research about some key technologies, the model LYZX low temperature screw pre-presser was manufactured successfully. The key technologies include pressing rate, pressing speed and rule of pressure variety, pressing time, heat preservation of the pressing process, measures of abrasion prevention and adjusting the property of oil seeds. The fact of production experiment and extending application proved that the machine can use not only for the new technics about the peeling and low temperature pressing of rapeseed, but also for the low temperature pressing of other oil seeds after adjusting suitably some technical parameters. So it possesses the extending application foreground.
