The use of oil expeller
Nowadays, mini-type screw oil expeller has been using more frequently than before. However, some users lack knowledge of using the machine properly, which leads to bad results such as low oil yield, poor oil quality, more breakdowns, low efficiency, etc. In the following part we will discuss the proper use of mini-type screw oil expeller, pre-pressing treatment of raw oil material, the refining of crude oil and the toeholds of common errors.

1).To assemble a newly-bought machine, users should choose a place which is big enough with sufficient sunlight and free flow of air. Then use cement to fix the base of the machine. The second step is to check according to the instruction whether the machine is assembled properly, whether the linking parts are firm and secure. In order to guarantee the normal use of the oil expeller, the third step is needed. That is to debug it before starting the machine. See whether there is loose or damage of components, whether noise is made while turning the strap wheel. Unless everything is in good condition, operating of the machine is not allowed. The right way to adjust the gap between the screw axis and the cake outlet ring is to tighten the screw to its end, then loosen it for 2-3 circles so as to assure the gap of the residue cake outlet between 0.5-1 millimeter.
2).Before oil cake or raw materials are put into oil expeller, users should make the machine work with nothing in it for a while, for about 3 to 5 minutes. Thus the gear box is warmed. Generally speaking, the temperature of the gear box should be kept higher or lower, but between 70 and 80 centigrade (feel hot while touching). Then it’s time to press.
3).Thickness of oil cake should be strictly controlled between 0.3 and 2.5 millimeter according to oil material varieties and the how many times it had been pressed. For more detailed date, please refer to the instruction of oil expeller. High oil yield materials such as sesame should be fed in batches (5 kilograms a time) and each group should be pressed 2 to 3 times. The first time press would bring out a lot of oil, which could reduce the temperature of the gear box. In order to assure normal use of the machine, second and third presses are need in which less oil is produced and less warmth lost. Thus the press temperature could go back to 70 to 80 centigrade as soon as possible. Every batch of material feed should follow the above order. Two ways are feasible to prevent the fed port from clogging up. One is to feed the machine evenly and the other is to remove the residue timely. The residue could be put back for another press. Before stop the oil expeller, users should feed the machine with oil cake instead of raw material so that residue can be expelled from gear box.
4).Propeller shaft should be drawn out when the oil expeller stop working. Fragment in clearance and gear box need to be removed timely so as to avoid trouble in the next use.
How to Choose oil expeller
1). Raw material for oil expeller
Now the oil expeller can be used for general processing of soybean, jatropha,peanut, sesame, rapeseed, canola, sunflower seeds, olives and other particles and also can be used for rice bran, corn germ powder, such as oil and safflower oil, and other few wild plants of oil-bearing materials.
2). How to purchase the oil expeller
When purchasing the oil expeller, first to see the appearance whether welding point is uniform , to check the machine whether lack spare parts, and then to turn the big belt pulley by hand to run several circles in order to check whether there is iron etc. foreign material in press barrel, whether blocked there, at the same time to well note whether gears mesh normally in gear box.
