Different from household oil pressing machines, this unit supports continuous feeding, low-temperature pressing and continuous cake discharge. It fully replicates the workflow of an industrial cold pressing production line. The complete test procedures including walnut kernel pretreatment, cold pressing and walnut cake discharging can be carried out on this machine. It can accurately collect test data such as oil yield, residual oil rate and physicochemical indicators of oil, providing reliable support for process research, parameter adjustment and production scale-up. Featuring a compact footprint and adjustable pressing parameters, it serves as an ideal laboratory device for nut oil research and specialty oil development.
