Hydraulic oil press is commonly used to press sesame oil, because hydraulic oil press can not only retain the original flavor of sesame, but also less investment, lightweight and convenient, easy to operate. The main parts of the hydraulic oil press are piston, hydraulic cylinder, column, movable upper beam, base, oil pump, barrel, electric heating ring and automatic temperature control device, etc. The pressing principle is to use the liquid pressure to increase the pressure on the piston of the press until the sesame oil in the oil material is pressed out. The following gives you an introduction to the hydraulic oil press is how to press the sesame oil.
Pre-pressing inspection: clear the mailbox and add enough hydraulic pressure, check whether the bolts in each part are loose, check whether the lines are connected correctly;
Preparation: first of all, preheating, preheating temperature: 50-70°C in summer and fall, 70-90°C in winter and spring, and then give the bottom of the press chamber a good mat, lower the piston to the right position, run the machine empty for 1-2min, winter and spring can be extended appropriately, generally 5-10min can be;
Oil extraction: in the bottom of the chamber mat good mat, will have been fried sesame exhaust smoke, loaded into the chamber, and then put the heat insulation board on the upper end of the chamber flat push into the chamber, adjusted to the appropriate height, lift the hand-controlled valve handle, boot press. Note that the press must be operated by a person, and the host is not allowed to leave the person in the process of career, so as to control the power supply in time (when the pressure gauge rises to 55 MPa, the electrical control system automatically stops, and the electrical automatic control system opens when the press chamber pressure falls to 45 MPa, and when the pressure gauge pressure rises again, no oil seeps out of the oil seam of the press chamber, which indicates that the oil has been squeezed out).
