How to operate oil extraction equipment normally?
Whatever the machinery and equipment, before using it must pay attention to the instructions below in order to use the process to better play its role. This is the benefit considerations. Before using the press, first of all should be ready assistive devices and containers, check and adjust the belt tightness. Then start the motor, the machine idling about 15min, check the speed of pressing screw shaft. Usually the speed should be around 33dmin. Do you want to pay attention to the idling gear box gear meshing and sound normal, each bearing location and whether the motor is normal. Press when idle, the motor current should be around 3A. The current is too high, should be immediately stopped to check and adjust after boot. After a normal load of small oil press, about 50kg ready rapeseed or soybeans, ready to put into the hopper. Note: at the beginning of the press can not feed too fast, otherwise the juice inside bore a sudden increase in pressure, pressing screw shaft rotation does not move, causing blockage virgin bore, and even squeeze cage rupture, a major accident. So at the beginning of the compression, the feed should be evenly slowly put into the hopper, so press were running together. So repeatedly, continuing more than 3 ~ 4h, so press the temperature gradually increased, and even risk of smoke (this is normal). When the press began to squeeze the chamber temperature is low, slowly twist the handle withered section studs, increasing the thickness of the cake, while increasing billet into juice moisture, temperature bore to be squeezed. Rose to about 90 ℃, the normal operation after the oil press, the cake thickness can be adjusted to 1.5 ~ 2.5mm, and tighten the nut tightened.
After the normal operation of small oil press, high oil content of fuel oil are mostly concentrated in the bar at the front row and row round group. Article drain oil at 60% of the total amount of oil out of the front row at the group round about 30%; and the end of the drain oil is small, not a drip line, oil color is very clear. Repeatedly pressed two or three times to the best of Resources rapeseed or soybeans, during which more diesel oil can be uniformly doped materials embryos press, to keep even when cutting, avoid erratic, otherwise it will affect the life of the oil yield and oil press. During operation should always check out the press cake cases and controls water blanks are neither too high nor too low. The cake should be a normal flaky, pressed by the screw shaft side smooth, the other side has a lot of hair pattern. As the cake loose weakness, or a shapeless cake, darker color, hand pinch Serve fragments, suggesting the billet add little water; as a cake weak, increased Cheng flake, or oil foam, Minga said that too much water. Under normal circumstances, no slag discharge between a round or rarely slag, slag in the bar at the discharge, such as slag was fine flaky described more water, the less water then the powder residue. In addition, the oil change position to see whether the water squeezed out of the right, when pressed into the water is too high or too low, the oil positions were moved back.
