Operating Method and Working Principle of Multi-function Screw Oil Press Machine
Automatic heating box, heating and pressing part, adjusting part, transmission part and vacuum oil filter are the main components of the multi-function screw oil press machine. When it is working, the power transmitted by the drive is transmitted to the spindle through the reducer, and the screw press mounted on the spindle rotates with it, pushing the oil crops forward. As the distance between the screw and the chamber decreases, the density of oil increases, so the pressure increases gradually. In the process of pressing, friction occurs between oil particles and machine parts, resulting in heat, which constitutes the two major elements of oil pressing technology, pressure and heat. Then, cell tissue of oil crops is destroyed, oil flows out of the outlet, and oil cakes are pushed out from the cone of the screw and outlet of the oil cakes. When the spilled oil flows into the filter bucket through the oil pan, the vacuum pump pumps out the air in the bucket, forming a negative pressure in the bucket. During the filtration process, the pump pumps the oil into the filter barrel, while the oil residue is left on the filter cloth.

Maintenance of Multi-function Screw Oil Press Machine
- After every 50 hours of operation, you should check the lubrication of this machine. The oil cup on the gearbox should not be short of oil. When adjusting the inner bearing of the screw, please add grease to each shift from the adjusting screw hole. Do not dry the grinding.
- The lubrication parts should prevent from dust and other impurities. The quality of the oil in the gearbox should be checked once a year. If deterioration is found, all the oil should be replaced.
- When the crushing quantity becomes low and the cake or oil is out of order, the screw axle should be pulled out, the screw and strip should be inspected, the wear condition of the cake ring should be checked, and the worn parts should be replaced in time.
- At the end of each work, the remaining oil cakes in the machine should be removed, and the dust and grease on the machine surface should be wiped off.

Pressing Methods of Several Main Oils (for reference only)
First, the machine is heated to 110 – 140 degrees Celsius, then the rapeseed is fried in a pot. When the rapeseed smokes in the pot, stir-fry it over low heat until the rapeseed is deep yellow, and then come out of the pot. Wait until the temperature drops to about 60 degrees Celsius before pressing the oil in the pan. Normally, the oil is yellow, and the cakes are black and yellow, large or long strips. In addition, due to the different tastes and usage between the north and the south, the south is slightly heavier in roasting rapeseed, while the north is relatively lighter.
Several problems easily arise in rapeseed pressing:
- More oil residue and lower oil yield: mainly because of the not enough coolingafter fried.
- The speed of oil filtering is slow: mainly in the process of rapeseed pressing, the impurities of raw materials are large, the dust is more and the temperature of various parts of the machine is lower, or the concentration of rapeseed oil is higher. At this time, the oil pan should be heated and opened. The other two filters should be used alternately, and the residue on the filter cloth should be removed, and the filter cloth should be cleaned and replaced.
- Vacuum pump oilinjection phenomenon: due to long-term filtration, vacuum expression to the limit value (-0.1), you can see from the window that oil droplets are rising. If the filter is continued, the oil will be pumped into the air bag, and then discharged from the exhaust hole of the vacuum pump, so that the oil yield will be reduced. When this happens, the vacuum pump should be stopped, so that the value of the vacuum meter can be reduced to – 0.09, and then continue to work.
The machine temperature rises to about 180 C. The peanuts are stir-fried until slightly yellowing. Then they are heated out and pressed. The oil is yellowish-white and the shape of oil cake is large or long.
The problems of peanut pressing are easy to occur.
- Oil return (i.e. oil flows out of the tail). The main reason is that the oil line is blocked and can be dredged by tapping the strip at the cutting edge with an iron rod. In addition, when frying peanut seeds, a small amount of water should be added to make the fried peanut elastic, which can avoid this phenomenon.
- The oil cake is broken.The main reason is that the temperature of peanut frying is low. When the peanut frying will be finished , the temperature should be increased and the fried peanut should be pressed in time.
- Vacuum pump injection. (ibid.)
Firstly, the machine is heated to about 140 degrees Celsius, then the soybeans are stir-fried until crackling. After the soybean is discharged, the temperature is lowered to about 60 ° C , and then to start the oil extraction. The oil cake is in a large block shape. If there is a scum phenomenon, it is caused by insufficient cooling after the seeds are fried or fried too light.
The machine is heated to 130-170 ° C, and the sesame is fried in a pot until it becomes round and swelled and turns yellow and oily. It is quickly raised several times, and after the black smoke is removed, the oil is reddish yellow, and the oil cake is in large or long shape.
Sesame pressing problems are easy to occur:
- The cake is not formed, the cake is broken, and the oil is splashed; the sesame is fried too lightly, and thetemperature of the fried sesame is too low.
- Oil cakes are wrapped around axles, cakes are tucked, noodle-like oil residue emerges between pressing bars, oil black, machine fumes are large, oil is bitter, feeding is slow, mainly caused by excessive stir-frying of sesame or high pressing temperature. In addition, too tight pressing screw adjustment may also cause this problem.
Successful Cases of Multi-functional Spiral Oil Press machine
In 2018, Kunal, a client from Nigeria, wanted to try to run a small oil mill. Due to limited of funds, after discussing with Tina, the customer service staff of our company, he only bought an oil press machine. In March 2019, he called our customer service number again and wanted to buy another two multi-functional spiral oil press machine again. He said that this oil press machine has brought him good benefits, he is eager to transform into a small and medium-sized oil mill, and hope to cooperate with our company again. Such a successful case is not an example, no matter you are just stepping into the industry or has already been a successful boss, Zhengzhou Taizy Machinery Co., Ltd. will not let your trust down, but will also provide you with the most effective service.
- It is strictly forbidden for foreign matter to enter the barrel, and forbidden to use hands or iron rods to enter the hopper to pull materials!
- When the machine is stuck, it is strictly forbidden to dismantle the spindle.
- When adjusting the thickness of the cake: (1) The action should not be too violent, in order to prevent the sudden increase of the machine load, causing the machine to jam, damage the machine parts, burn down the motor, etc. (2) During the working process, it is not appropriate to loosen the adjusting screw excessively so as to prevent the screw from falling off from the previous support, so that the screw can not be loaded or removed.
- The processed dry cake can not be repeatedly pressed back and forth to avoid jamming the machine.
- When replacing the filter cloth, the filter cylinder must be pressed into the rubber ring groove, otherwise the filter cloth will leak or crush.
- Insufficient heating of the machine is not allowed for press.
