Method for extracting passiflora seed oil from passiflora seeds

Abstract

This invention has disclosed a method for extracting seed oil from passionflower seed, it includes the following step: (1)Crush passionflower seed to dry, crush to 20-50 mesh, put it in the material tube of the extraction jar; (2) set up cold case temperature for extraction at - - 3 Deg. C, injet the liquified CO2 into the extraction cauldron passing through the purify machine and the preheater by using a high-pressure pump, the pressure up to l5MPa- 30MPa, the temp is 35 60 Deg. C and the extraction time for 4-5 hours; (3)Separate the CO2 fluid dissolved with oil which enters the separating cauldron from the extraction jar , the pressure of separating cauldron ó± is 8MPa- 12MPa, temperature is 35 - 60 Deg. C, the pressure of separating cauldron ó� keeps being balanced with the way of escape, temperature keeps 35 - 55 Deg. C. Advantages: high efficiency in extracting, energy consumption is low, the products are of high quality, there is no solvent to remain, pollution-free to the environment.
