I do not know the majority of users in the use of press equipment in the process will encounter some problems, such as pumps press equipment no way normal oil absorption, which is why? The solution? We can see from the following aspects: First, check for dirt clogging the oil network, if it is, then they would open the oil network, clean up dirt, oil network if there is no dirt, do what you want to consider whether or not oil fluid utilization over time, oil press, oil use over time, there will be a lot of sediment, which precipitates adhered to the inlet of the valve, causing unable suction phenomenon, this happens, either oil filter, or to replace oil, either filtration or oil change, after the inlet valve should be cleaned. Finally, remind the user to press the device at the time of purchase, press which brand is good, not because of the price to buy cheap oil press oil press equipment, so you would be wasted. Many people do not know what is refined standard, based on hearsay evidence and asked some strange questions, such as: the height of the screw press squeeze you out of the oil refinery can meet the state standards? Screw press oil can be squeezed out of the direct fill it? Whenever I see such problems Xiao Bian also very helpless, really can not start, I do not know where the answer from ah. Today with this opportunity to popularize and edible oil of classification criteria for you. Oil often buy in the supermarket knows, supermarket cooking oil can be divided into "One, two, three, four" levels, then the grade is what does that mean, respectively, they represent? Oil countries to develop new Standard refined edible oil according to its degree is divided into four. As the name implies, press equipment, the higher the level, also on behalf of the oil level, the better, then what is it not the case, many consumers believe that eating an oil, two oil than the three oil, four oil to health . According to insiders, in fact, the level of oil refined according to the different degrees to the division, but does not mean it's nutritional value is higher, so you can not just look at the degree of refining oil is high, we must consider whether the nutritional value of the oil high, because of the high degree of refining, indicating that the higher the temperature, and it will lead to the passage of nutrients. Vegetable oil available in the market with a variety of raw materials, largely soybean, rapeseed, peanut, corn, oil seed, these vegetable oils are rich in unsaturated fatty acids and more phytosterols, squalene, carotene, vitamin E and other nutrients, but want the oil rate of these plants, it is necessary that the temperature increases, the opposite will be reduced nutrients.
