Note: The above parameters refer to the complete selection, separation, and rolling auxiliary equipment, reasonable process, and normal operation that can achieve the indicators.

2、 Working principle and structure of 6YL-125 spiral oil press:
1. Working principle:
When the oil press is running, the processed embryo is carried into a hopper, and the oil enters the press chamber from the hopper. The spiral with a squeezing screw is pushed inward for squeezing.
Due to the fact that the embryo is in operation within the oil press chamber, significant frictional resistance is generated between the embryo, the screw, and the chamber under high-pressure conditions. This can cause friction between the raw material and the raw material, resulting in relative motion. On the other hand, the diameter of the root circle of the squeezing screw gradually increases. When the squeezing screw rotates, the thread allows the embryo to both move forward and flip outward. At the same time, the material layer near the surface of the squeezing screw thread rotates with the squeezing shaft, so that each embryo particle in the squeezing chamber does not move at the same speed and direction. And there is also relative motion between particles. The heat generated by friction satisfies the necessary heat for the oil extraction process, which helps to promote the thermal denaturation of proteins in the embryo, destroy colloids, increase plasticity, and reduce the viscosity of the oil, making it easy to separate and extract oil, thus improving the oil extraction rate of the oil press.
2. Structure: The machine consists of five main parts: feeding hopper, gearbox, pressing chamber, pressing screw, and frame, as shown in the figure
(1)

3、 Installation of the machine:
The oil press must be installed on a solid foundation with anchor bolts to keep the machine level. The motor is installed on the back of the feeding hopper.

4、 Lubrication of the machine:
1. Oil presses mainly use two forms of lubrication: oil and butter. The refueling cycle is shown in Table 2

Five Machine operation:

（1） Key points before starting up:
Before starting up, fill the gearbox with 12 kilograms of engine oil
After installing the machine, add lubricating oil according to regulations, check whether all components are fastened, and whether the operating handle and plug plate are flexible
3. Use your hands to move the large pulley and check for any looseness or jamming of the machine. If there are any abnormalities, promptly eliminate them
4. Adjust the tightness of the belt, start the motor, and check if the direction of the pulley is consistent with the marked direction
After the preparation work for the inspection is completed, loosen the locking nut and screw the press screw to the dead center, then retract 3-4 turns, and move forward half a turn to ensure the gap between the press screw and the cake outlet
