Pre press is a kind of continuous pre press equipment, which can be used for one machine (one-time press and pre Press). It has the characteristics of reasonable design, low energy consumption and small floor area. Power supply: 380V, matching power: 7.5kw-11kw motor.
Structure and working principle of pre press:
Structure: the equipment is mainly composed of three-layer auxiliary steam frying pan, feeding mechanism, press cage, press screw shaft and transmission device.
Principle: after steaming and frying, the billet enters the three-layer auxiliary steaming and frying pan for steaming and frying again, and then the material is continuously sent into the pressing chamber through the feeding mechanism. As the space between the pressing screw shaft and the pressing cage gradually shrinks along the forward direction of the material, the billet is under strong pressure, most of the grease is pressed out, and flows out through the gap of the pressing bar, and then discharged after pressing at the end of the pressing screw shaft It's my cake.
Features of pre press:
1. Perfect structure, large processing capacity, reduced workshop area, power consumption, operation management and maintenance.
2. The structure of pressed cake is loose but not broken, which is conducive to solvent penetration.
3. The oil content and water content of pressed cake are suitable for solvent extraction.
4. The quality of pressed oil is better than that of pressed or leached oil.
