How to Use Oil Press,Oil Extraciton,Oil Pressing Machine

Before opening the electric motor of the oil press, first check the tightness of the transmission belt. Let the machine run idle for 15 minutes and check for contact between the gears. See that these parts are undamaged. The electric current should be around 3A while the machine is idling. If the electric current is excessive, immediately stop the machine and recalibrate before restarting.

When empty running is ok, prepare about 50 kg rapeseed or soybean, ready to put into the feed hopper. Well note that at the beginning of pressing, the feeding of material can not be too fast. Otherwise when the pressure increase suddenly in press barrel, the screw press worm can not run, resulting the block in press barrel, even broken caused serious accident. Thus begin pressing, the feed of material shoulbe be slowly into the hopper so that the oil press run in. So repeated, last more than 3 ~ 4 hours, the temperature gradually increased ready to press, or even smoke (this is a normal phenomenon).

At the beginning of pressing, the temperature is lower in press barrel, can move the handle slowly on the worm shaft, to increase the thickness of the meal. While increasing the moisture of material, waiting for the suitable barrel temperature. Rising to 90 ℃, when oil press running normally, change the thickness of cake into 1.5 ~ 2.5 mm, and fastening the fixed nut.

After determining that the machine is safe for operation, prepare 50 kg of rapeseed or soybeans for the feeder of the oil press. Be cautious as to the following: initial feedstock should be limited to slow speeds and well-proportioned quantities, or the chamber of the oil press will become blocked or broken. So users should feed materials evenly at the beginning. After time, the temperature in the press chamber will rise. In order to quicken the warming process, users may screw the hand shank on the double-screw bolt.

After 2 or 3 times of repeated pressing, the extraction of oil can be out for rapeseed and soybeans. During this period, the oil residue contented high oil can be mixed with material into feeding. The feeding of material need keep evenly, avoid of more or less for a while. Otherwise the life of oil press and oil extraction rate will be affected.

When oil press running, should check the output condition of meal regularly. And control the moisture of material neither too high or too low. Normal meal should be flake with smooth on one side close to pressing screw worm and rough veins on the other side. If the meal is too loose, out of shape, dark color and easy broken by hand, that is too little water added into material caused. If the meal is soft, big flake, and too much foam in extracted oil, that is too much water caused.

Under the oil press in normal operation, the high oil-content material is expelled at the strip and round raft with oil quantities of 60% and 30%, respectively. The rear of the oil press expels oil in small amounts, in drips but not streams. The oil is light in color. The oil in rapeseed or soybeans can be thoroughly pressed after two or three cycles. During the repressing process, users can put residue which contains a lot of oil into the machine for further pressing. Evenly feed the stock into the machine or it will affect the ratio of oil extraction and the life expectancy of the oil press machine.
