What problems should be paid attention to when buying an oil press
Some customers are confused when they want to buy an oil press, because there are too many manufacturers and types of oil presses; in fact, as long as you know what you need, it is more appropriate to know what you need after consulting with many parties.
How to clarify your own needs: what oil crops to press, no oil press on the market is particularly versatile, if the customer is pressing peanuts, soybeans, oil sunflower, rapeseed and other crops, it is recommended to consider screw oil press or full Automatic oil press. If the customer presses sesame seeds, a hydraulic oil press can be considered. When the oil press presses different oil crops, there will be different working principles and pressing methods; the model of the oil press can be requested according to the output required by itself. Of course, customers can choose the appropriate size according to their budget, plant area, and output size. Own model of screw press.
The problem of understanding the principle of the oil press: Under normal circumstances, more than 90% of the oil has been squeezed out of the oil embryo after the first stage of pressing. After that, when the number of pressing stages is increased, the oil that is squeezed out can only be less than one at a time. For materials with low oil content, secondary pressing can be used. Practice has proved that when the four-stage press type shown in the figure below is used to squeeze materials with low oil content, the third and fourth stages have no oil. When pressing high oil content materials, only a very small amount of oil is discharged in the fourth stage. Ask the oil press manufacturer about the material used in the oil press, whether it is a wear-resistant and compression-resistant material, and what processes are used to produce it, including the materials used in auxiliary machines. How about the processing performance and how easy it is to operate.
Some unscrupulous merchants have seized the psychology of some users who are greedy for cheap, and often offer very low prices, which are beyond the general market rules, so there are problems with the parameter configuration and quality of the oil press. .
