  • What is the difference between Hot Press screw oil press and cold pressing?
  • The hot-press screw oil press is usually used in hot rolling. Oil extraction by cold pressing refers to the state of oil without heating or low temperature before pressing, which is sent to the oil press for pressing. The cold pressing method is generally processed under the environment of fewer than 60 degrees Celsius.
  • How to increase the yield of cold pressed oil?
  • If you want to increase the oil yield of the cold press, you have to crush it before you can go up. Sometimes you have to press it twice and press it three times. Most of the vegetable oils consumed in daily life are hot pressed oil.
  • What is oil extraction by hot pressing?
  • Oil extraction by hot pressing usually involves cleaning, crushing and high-temperature heating before oil extraction, which results in a series of changes in the interior of oil: destroying oil cells, promoting protein denaturation, reducing oil viscosity and so on, so as to be suitable for oil extraction and increasing oil yield.
  • What are the disadvantages of cold pressed oil?
  • Cold pressed oil color is good, relatively light, but the oil is not fragrant, not on fire. The disadvantage is that the oil yield is not high, most of the raw materials are not suitable for cold pressing; generally, the cold pressed cigarettes are low and the water content is unstable, which is not conducive to long-term storage.
