[0018] 1. Examples of different types of distillates
[0019] (1) Add 0.6kg urea to 4.5L 95% ethanol, dissolve it at 60~80℃, then add 1kg soybean oil vacuum deodorant distillate, stir well, vacuum degassed, sealed package, put in an ultra-high pressure container and apply 300MPa pressure 1 hour, take it out and filter to obtain a filtrate rich in VE, PUFA and squalene. The acid value of the filtrate (mg KOH / g) can be reduced from 60 to below 40; the recovery rate of PUFA and squalene (total content in the filtrate / The total content in the raw materials) is above 85%, and the VE recovery rate can reach 95%.
[0020] (2) Add 1.5kg of urea to 11.25L of 95% ethanol, dissolve it at 60~80℃, then add 1kg of rapeseed oil vacuum deodorized distillate, stir well, vacuum degassed, sealed package, and place in an ultra-high pressure container to apply 250MPa After 1 hour of pressure, take it out and filter to obtain a filtrate rich in VE, linoleic acid and squalene. The respective recovery r...
