Embodiment 1

[0024] 1. Microwave drying and sterilization of live Tenebrio molitor:

[0025] The temperature is 65-80°C, the drying time is 15 minutes, and the moisture content of the dried Tenebrio molitor after drying is 8.14%.

[0026] Explanation: If the water content is too high, it is easy to form a continuous phase water film on the surface of the particles, hindering diffusion, reducing solubility, easy to cause clogging, and poor oil quality, so the water content should be controlled at 6%-10%.

[0027] 2. Crush the dried Tenebrio molitor and sieve it through a 20-mesh sieve;

[0028] 3. Weigh 16 kg of Tenebrio molitor fragments through a 20-mesh sieve and put them into the extraction kettle (volume 50 liters, HA221-40-100 type), close the valve, and use CO 2 High pressure pump pumps CO 2 gas. Pressure 30Mpa, temperature 45°C, keep for 60 minutes;

[0029] 4. Open the valve between the extraction kettle and the first separation kettle so that the CO in the extraction kettle 2...

[0039] 2. Crush the dried Tenebrio molitor and sieve it through a 14-mesh sieve;

[0040] 3. Weigh 20 kg of sieved Tenebrio molitor fragments and put them into the extraction kettle (volume 50 liters, HA221-40-100 type), pump in CO 2 gas. Pressure 28Mpa, temperature 50°C, keep for 40 minutes.

[0041] 4. The pressure of the first separation tank is 12Mpa, and the temperature is 50°C, keeping it for 15 minutes.

[0042] 5. The pressure of the second separating tank is 6Mpa, and the temperature is 30°C.

[0043] 6. The pressure in the rectification stage is 16Mpa, and the temperature distribution from the bottom to the top of the rectification column is 35°C, 40°C, 45°C and 48°C respectively.

[0044] 7. Obtain 4.70kg Tenebrio molitor oil, with an oi...

[0047] 1. Microwave drying and sterilization of live Tenebrio molitor:

[0048] Microwave working chamber: the temperature is 73-84°C, the drying time is 10 minutes, and the moisture content of dried Tenebrio molitor is 10.0%.

[0049] 2. Crush the dried Tenebrio molitor and sieve it through a 30-mesh sieve;

[0050] 3. Weigh 15 kg of sieved Tenebrio molitor fragments and put them into the extraction kettle (volume 50 liters, HA221-40-100 type), pump in CO 2 gas. Pressure 32Mpa, temperature 35°C, keep for 100 minutes.

[0051] 4. The pressure of the first separation tank is 14Mpa, and the temperature is 40°C, keeping it for 20 minutes.

Abstract

The present invention relates to a refining method of flour weevil oil, and is characterized in that after being dried and filtered, a flour weevil makes a supercritical carbon dioxide fluid extraction and an extractive matter separating working procedure treatment; the water content of the flour weevil after being dried is 6 to 10 percent; the filtering granularity of the dry flour weevil is 14 to 30 mu; the pressure of the supercritical carbon dioxide fluid extraction is 20MPa to 40MPa, the extraction temperature is 35 to 55 DEG C, the flux of carbon dioxide fluid is 800L to 1200L per hour, and the extraction time is 40 minutes to 100 minutes. The present invention refines flour weevil oil adopting the international most advanced supercritical carbon dioxide extraction technology, and has the advantages of high efficiency, little energy consumption, no rudimental solvent, no pollution, good security, high oil quality and so on. The present invention plays a very important role in advancing the industrialized exploitation of the flour weevil, promoting the adjustment of industrial structure in countryside, and building a new socialist countryside.

Description

technical field [0001] The invention relates to insect agricultural product processing technology, in particular to a method for extracting oil from Tenebrio molitor. Background technique [0002] Tenebrio molitor has the characteristics of fast growth and high reproduction coefficient, and its main food is crop waste; Tenebrio molitor is rich in various nutrients and has high development value. Factory farming has been realized, and the national annual output has reached more than 100,000 tons; The industrialization and development of Tenebrio molitor has been included in the "Harvest Plan" of the Ministry of Agriculture by the state, and the prospect is very broad. At present, the application of Tenebrio molitor is limited to the bait of special breeding animals, comprehensive deep processing is still blank, and the extraction and application of Tenebrio molitor oil is still in its infancy, and Tenebrio molitor oil is a high-end health food and can also be used as an impor...
