Notes On The Use Of The Oil Press
1.The motor current of the oil press should be controlled at about 3A.If the current is too high when the oil press is running, we should stop immediately to check and adjust the machine problem before word to start the machine for no-load operation.
2. After the no-load is normal, prepare about 50kg of rapeseed or soybean and prepare to put it into the feed hopper. When you start pressing we can not put the material too fast, if the material is fed too fast there will be a sudden increase in pressure in the press chamber, resulting in the press screw shaft does not turn, resulting in blockage of the press chamber, the situation is serious can cause the press cage rupture, which will cause a major accident.
Therefore, when the compression starts, the feed should be put into the feed hopper evenly and slowly, so that the oil press can run together. Repeat this many times, for 3 to 4 hours after the oil press temperature gradually rise, and even smoke (this is a normal phenomenon).
Start pressing when the chamber temperature is low, you can slowly twist the handle on the adjusting stud to increase the thickness of the cake, while increasing the moisture into the press embryo material, to be squeezed chamber temperature to about 90 ℃, after the normal operation of the oil press, you can adjust the thickness of the cake to 1. 5mm-2. 5mm, and tighten the fastening nut.
3. After the normal operation of the oil press, the oil content of high oil mostly concentrated in the strip row and the front group of round row. The oil output at the bar row accounts for about 60% of the total oil output, and the front group round row accounts for about 30%: while the end discharge oil is very little, into drops not line, the oil color is very clear.
Repeatedly squeeze two or three times can be rapeseed or soybean oil squeezed out, during this period can contain more oil residue evenly mixed into the material embryo in the press, a divination material to maintain uniformity, avoid when more and less, otherwise it will affect the life of the oil press and oil yield.
4. When pressing to frequently check the oil press cake situation, and control the embryo moisture is neither too high nor too low. The normal cake should be flaky, smooth on one side of the press screw shaft, the other side has a lot of hair lines.
Out of the cake can also reflect some situations.
first: out of the cake is loose and weak, or out of the cake is not formed, darker, with a pinch that the hand into pieces, which indicates that the embryo material with less water; Second: out of the cake is soft, into a large flake, or out of the oil foam increases, it means that the water is too much. Under normal circumstances, no slag or little slag between round rows, slag in the row of slag, such as slag is fine flakes that more water, out of the powder slag means less water. In addition, the change of oil position can be seen in and out of the squeeze moisture is appropriate, when the water into the squeeze is too high or too low, the oil position are moved back.
