manufacturing technique
1, squeezing method
(1) Hot pressing method: Oil crops are fried by high-temperature fire or steam, and then the oil is physically pressed, which is a relatively traditional pressing process with high oil yield.
(2) Cold pressing method: under the condition of low temperature, it is squeezed by huge pressure of physical machinery. Without the traditional high-temperature frying or steaming process, the oil is still distributed in the undeformed protein cells, which is rich in the inherent components of flaxseed.
2. Leaching method
The oil produced by leaching process is also called leaching oil, that is, the oil is leached with organic solvents (such as gasoline and ethanol). The leaching method is an oil-making process that uses solvent oil (No.6 light gasoline) to soak the oil raw materials and extract them at high temperature, so that the oil can be extracted.
