[0018] 1. Examples of different types of distillates
[0019] (1) Add 4.5L 95% ethanol to 0.6kg urea, dissolve it at 60-80°C, then add 1kg soybean oil vacuum deodorization distillate, stir evenly, vacuum degassing, seal the package, put it in an ultra-high pressure container and apply a pressure of 300MPa After 1 hour, take it out and filter to get 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 raw materials) is above 85%, and the recovery rate of VE can reach up to 95%.
[0020] (2) Add 11.25L 95% ethanol to 1.5kg urea, dissolve it at 60-80°C, then add 1kg rapeseed oil vacuum deodorization distillate, stir evenly, vacuum degass, seal the package, put it in an ultra-high pressure container and apply 250MPa Pressure for 1 hour, take out and filter to obtain filtrates rich in VE, linoleic acid and squalene, and thei...
