Benefits of technology

This technology makes it easier for people who want more extracting power from their food than they can handle with less effort or without any harmful chemicals like alcohol that are used during processing.

Problems solved by technology

This patented technical problem addressed in this patents relates to extracting highly pure flavorful volatile substances (such as lycopene) from plants called cracker seals that contain large amounts of these compounds for use in various applications like food products. Current methods require expensive equipment with hazardous chemical reagents used during processing.

Embodiment 1

[0011] (1) 2 kilograms of passionflower seeds are washed and dried, pulverized into 30 orders and put into the barrel of 5L extraction tank 8; (2) turn on refrigeration and cold cycle, and the temperature of cold box 5 is set to 0°C; Set the temperature of extraction cylinder 8 to 45°C, the temperature of separation kettle I10 to 40°C, the temperature of separation kettle II12 to 55°C, and turn on the CO 2 Cylinder 2, CO 2 Come out from the steel cylinder 2, enter the cold box 5 for liquefaction through the gas purifier I3, and then start the high-pressure pump 6 to convert the CO 2 After the purifier II4 and the preheater I7 enter the extraction cylinder 8, boost the pressure to 30MPa, making it a supercritical fluid for extraction in the extraction cylinder; (3) the CO 2 The fluid is decompressed from the extraction cylinder 8 and enters the preheater II9 to be preheated before entering the separation system. In order to realize the complete separation of unsaturated fatty ...

Embodiment 2

[0013] 2 kilograms of passionflower seeds are washed and dried, crushed to 40 mesh; the pressure of the control extraction cylinder is 15Mpa, the temperature is set to 35°C, the pressure of the separation kettle I is adjusted to 8Mpa, and the temperature is set to 55°C, and the separation kettle II The temperature setting is 40 DEG C, and other is the same as embodiment 1, extracts 5 hours, collects 516 grams of fats and oils, and extraction rate is 25.8%.

Embodiment 3

[0015] Control the pressure of the extraction cylinder to 20Mpa, set the temperature to 55°C, adjust the pressure of the separation tank I to 10Mpa, set the temperature to 35°C, set the temperature of the separation tank II to 35°C, and keep the rest of the conditions unchanged, extract for 4.5 hours, collect 500 grams of oil, the extraction rate is 25%.

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.
