If the machine is not heated, the material will only be squeezed into a paste out and the grease cannot be separated.

4、 material cold pressing mode, the normal temperature of grease out of about 40 °, the nutrients will not be lost.

Material hot pressing mode, the oil yield is a little higher, the oil will be more fragrant, oil out of the temperature of 60-80 degrees 5, so the hot pressing mode is generally suitable for pressing rapeseed, peanut and other low-value cooking oil, the pursuit of oil yield and fried fragrance; cold pressing mode is generally suitable for pressing walnut oil, flaxseed, almond, olive kernel and other high-nutrition supplement oil, to ensure that nutrition is not lost.
