Before using the screw oil press machine, first of all aids and containers should be prepared to check and adjust the tightness of the belt. Then start the motor, make the machine run around 15min, check the speed of the squeeze screw shaft. The general speed should be around 33dmin. When idling, pay attention to the meshing condition of the gears in the gear box and whether the sound is normal, and whether the bearing parts and the motor are normal. When the oil press idling, the motor current should be about 3A. If the current is too high, it should be stopped and checked immediately.

 

After normal idling, prepare about 50kg of material and prepare it for input into the hopper. Note: When the press is started, the feed cannot be too fast. Otherwise, the pressure inside the press squeezing suddenly increases, the squeezing screw shaft does not move, and the squeezing squash is blocked, even the squeezing cage is broken, and a major accident occurs. Therefore, when starting the compression, the feed should be evenly and slowly put into the hopper to run the oil press. Repeatedly for many times, lasting more than 3 to 4 hours, the temperature of the oil press is gradually increased and even smoke is emitted (this is a normal phenomenon). When the squeezing is started, the temperature of the squeezing sorghum is low and can be slowly twisted. The handle on the stump studs increases the thickness of the cake, and at the same time increases the moisture content of the infused billet until the temperature of the squeezing smash. Raise to about 90 °C, after the normal operation of the oil press, cake thickness can be adjusted to 1.5 ~ 2.5mm, and tighten the fastening nut.

 

After the normal operation of the oil press machine, the oil with high oil content is mostly concentrated in the row and the front group round row. The oil at the bar row accounts for about 60% of the total oil output. The round row at the front group accounts for about 30%; the oil at the end of the row accounts for only 30%. Repeatedly press two or three times to squeeze out the oil of rapeseed or soybeans. During this period, the more oily oil residue can be evenly mixed with the embryos, and the material should be kept even when it is unloaded. Otherwise it will affect the oil press life and oil rate.

 

During the operation, it is necessary to constantly check the cake output of the hemp oil screw press machine, and control the moisture of the billet neither too high nor too low. The normal cake should be in the shape of a sheet, smooth on one side of the screw axis, and a lot of hair on the other side. If the cake is loose and weak, or the cake does not form, the color is darker, and it will be broken into pieces by hand. This shows that the filling material is too little water; if the cake is soft, large flakes, or oil foam increase, It means adding too much water. Under normal circumstances, there is no slag or little slag between the round rows, and slag is discharged at the bar row. If the slag is fine, it indicates that there is much moisture, and the powdered slag shows that there is less water. In addition, it can be seen from the change of the oil outlet position whether the moisture content is suitable or not. When the moisture content is too high or too low, the oil outlet position is moved backwards.
