AI Technical Summary
Existing peanut cold pressing technology has low oil extraction efficiency, and the oil is easily retained in the pores inside the peanut cake, resulting in low oil yield and high production cost. Furthermore, excessive pressure can easily cause peanut cake to clump and the pressing chamber to become clogged.
The pressing plate driven by a hydraulic cylinder, combined with a rotary drive mechanism, and a negative pressure oil outlet component and a crushing component, achieves efficient release and discharge of oil through the synergistic effect of axial pressure, rotational force and negative pressure adsorption, avoiding pressure release and blockage.
It improves the oil yield of cold pressing, reduces impurities in crude oil, extends equipment life, reduces energy consumption and production costs, and is suitable for the high viscosity and poor fluidity of cold-pressed oil.
