Detailed Description
In view of the above technical features, the main effects of the method for manufacturing black soldier fly oil according to the invention will be clearly demonstrated in the following examples.
Referring to fig. 1, the method for manufacturing hermetia illucens oil according to the embodiment of the present invention includes steps S101 to S106:
step S101, washing the hermetia illucens with a solution, wherein the solution is tap water or deionized water, and the hermetia illucens is scalded by hot water after being washed, and the temperature of the hot water is between 40 and 60 ℃.
Step S102, the cleaned black soldier fly is placed in a drying space, the drying space is provided with a microwave dryer, 1 kilogram of the black soldier fly is dried into a dried worm by the microwave dryer, the moisture content of the dried worm is suitable for subsequent oil extraction, the power of the microwave dryer is between 300w and 700w, the temperature of the drying space is between 26 ℃ and 30 ℃, and the drying time is between 40 minutes and 45 minutes.
Step S103, the dried worm is placed into a spiral oil press, the dried worm falls into a conical spiral axis of the spiral oil press and then is pushed along with the rotation of the axis, the space between the threads and the space of the pressing chamber are gradually reduced, the dried worm is pressed to spirally extrude hermetia illucens oil, and the dried worm after oil pressing is discharged from the pressing chamber. It should be noted that the black soldier fly oil extruded by the oil press after microwave drying has less impurities, and the dry particles after oil pressing are finer, which can increase the yield of the black soldier fly oil by about 20% to 25%.
And step S104, placing the hermetia illucens oil for precipitation, wherein the precipitation time is less than 40 minutes, and separating the impurities in the hermetia illucens oil from the hermetia illucens oil through precipitation.
Step S105, putting the precipitated hermetia illucens oil into a vacuum filter, performing vacuum filtration on the hermetia illucens oil through the vacuum filter, and performing vacuum filtration on impurities which cannot be precipitated in the hermetia illucens oil.
Step S106, putting the hermetia illucens oil into a supercritical extraction separator, wherein the pressure of the supercritical extraction separator is between 14.7psi and 3600psi, the pressurization is sequentially performed from 14.7psi to 3600psi, the temperature of the supercritical extraction separator is between 35 and 45 ℃, and the extraction time of the supercritical extraction separator is between 35 minutes and 45 minutes, so that the purified hermetia illucens oil is obtained.
