混合油负压蒸发工序：
从浸出器流出的液体是含有油脂和溶剂的混合油。将混合油中的溶剂分离出来是利用溶剂和油脂的汽化温度不同，我公司目前主要采用负压蒸发工艺，可减少溶剂的泄露，降低溶剂的消耗。分离出的溶剂汽体进行冷凝冷却回收后送回浸出器再次使用，提溶剂的使用效率。
负压蒸发的优点：
1、负压蒸发蒸发效率，脱溶充分，毛油中溶剂消耗低。
2、利用蒸脱机的二次蒸汽和蒸汽喷射泵的余汽作为蒸的热源，可节约能源，同时减少冷凝器的配置面积，节省投资。
3、由于汽提的温度低，毛油的色泽浅、质量好、残溶低。
Miscella Vacuum Evaporation Process:
The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses vacuum evaporation technology, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency.
Vacuum Evaporation Advantages:
1. Vacuum evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil.
2. Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save energy, reduce the condenser configuration area and save investment.
3. Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.
