Squeezing process of hydraulic oil press machine

Preparation work  :Clean the fuel tank and add enough hydraulic oil, check whether the bolts in all parts are loose, and check whether the line connection is correct.

 

1 Preheating before each oil press, preheating temperature: 50~70°C in summer and autumn, 70~90°C in winter and spring. The preheating system is automatically controlled, and it is not necessary to turn off the temperature control switch

 

 

2 Hold the handle of the upper roof, fully open the upper roof, and the working position is 180 degrees, lay a cushion on the bottom of the chamber, and drop the piston into position and stand by.

 

3 Run the machine for 1~2 minutes before each oil press. If the hydraulic oil becomes thicker in winter and spring, it should be run for 5-10 minutes to make the oil thin and easy to operate.

 

4 Put the fried sesame seeds into the chamber .

 

5 Place the mat on the upper end of the pressed hemp seed, and place the partition plate on the upper end of the press squeegee and push it into the squeeze. If the oil is small, the oil can be raised at the time of starting, so that the oil is kept at the upper plane slightly lower than the upper end surface of the press; otherwise, the upper top plate is not closed, the handle of the manual valve is lifted, and the machine is started.

 

 

6 The hydraulic oil press machine  must be operated by a special person. The main engine is not allowed to leave the person during the boosting process. When the pressure is expressed to 55 MPa, the motor stops working. Otherwise, the power should be turned off immediately to check whether the pressure gauge is damaged or not, and the AC contactor is damaged. If it is damaged, it should be replaced immediately after checking and then turned on.

 

7 When the pressure gauge rises to 55 MPa, the electrical control system automatically stops. When the pressing pressure drops to 45 MPa, the electrical control system automatically opens, the pressure of the pressure gauge rises again, and the oil is squeezed out of the oil seam. Indicates that the oil has been drained.

 

8 Turn off the oil press machine :Hold the handle of the manual control valve, press down the valve core of the manual control valve, and lower the pressing force to 10 mm according to the top. Lift the handle of the manual control valve and open the upper top plate.

 9 Open the machine : the sesame cake rises, the top plate of the piston is about 5 mm above the upper end of the press, shut down, take off the separator plate and the upper mat, and take out the oil cake.
