Description

Method for producing black soldier fly oil

The invention relates to a method for producing black soldier fly oil, in particular to the process of extruding the black soldier fly oil through a screw oil press, and then extracting the black soldier fly oil by a supercritical extraction separator. into purified black soldier fly oil.

The English name of Black soldier fly (Black soldier fly), is a kind of saprophagous insects belonging to the family Diptera. Black soldier flies can feed on livestock manure and domestic garbage, and their larvae are called "Phoenix worms", which are as famous resource insects as fly maggots, mealworms, barley worms, etc., so they are vigorously promoted by various countries. Black soldier fly larvae contain 40% to 45% protein, 32% fat, 7% ash, 280mg/100g amino acid nitrogen, 172.7mg/100g cholesterol, and 0.235mg vitamin B1 /100g and 7 kinds of even carbon fatty acids, namely lauric acid, oleic acid, palmitic acid, linoleic acid, myristic acid, stearic acid, capric acid. For example, there is Mainland Patent Publication No. CN110484348A "A method of pressing and extracting oil from black soldier flies", which discloses step 1): pretreatment of black soldier flies, placing the sieved black soldier fly larvae in a basin for two days to allow them to be fully discharged Enteric food, put it into a mesh bag for freezing and low temperature inactivation; step 2): cleaning, when the black soldier flies die, put the mesh bag into an ultrasonic cleaner to remove impurities on the surface of the worm and its excrement; step 3): drying After drying, the mesh bag black soldier flies are placed to drain the water and then sent to a tunnel dryer to dry the black soldier flies to 20% moisture. The above-mentioned black soldier fly oil extraction method cannot purify the components in the black soldier fly oil, so that the product application of the black soldier fly oil is relatively rare.

The present invention is a kind of black soldier fly oil manufacturing method, comprises:

cleaning a black soldier fly;

Put the cleaned black soldier flies in a drying space, the drying space has a microwave dryer, the power of the microwave dryer is between 300w and 700w, and the temperature of the drying space is between 26°C and 26°C. Between 30 degrees, the drying time is between 40 and 45 minutes;

The dried black soldier flies are put into a screw oil press, the black soldier flies are screwed out of a black soldier flies oil, and the black soldier flies oil comprises: parts by weight are between 20 to 24 A fat, a weight part of an amino acid between 38 to 40, a weight part of a monolauric acid between 46 to 58, a weight part of a protease between 17 to 22;

The black soldier fly oil is placed for precipitation, and the precipitation time is between 25 and 40 minutes;

This black soldier fly oil after the precipitation is put into a vacuum filter, and this black soldier fly oil is vacuum filtered;

Put the black soldier fly oil into a supercritical extraction separator, the pressure of the supercritical extraction separator is between 14.7 psi to 3600 psi, and the temperature of the supercritical extraction separator is between 35 degrees Celsius to 45 degrees Celsius In between, the extraction time of the supercritical extraction separator is between 35 minutes and 45 minutes, and a purified black soldier fly oil is obtained.

Through the above technical features, the following effects can be achieved:

1. The present invention extracts the components in the black soldier fly oil through the supercritical extraction separator, which can shorten the production time, avoid the damage of the material structure of the extract due to high temperature, reduce the consumption of the organic solvent, and improve the production rate to 90%. %, and through the extraction of black soldier flies oil, the products related to black soldier flies are more widely used, such as cosmetic additives, food additives, feed additives, fertilizer additives, plant pest control agents and animal and aquatic biological control agents.

2. The present invention adjusts the pressure in the pressurization process through the supercritical extraction separator, so that the black soldier fly oil can be purified and separated and the purity of the components in the purified black soldier fly oil can be improved.

In view of the above technical features, the main effects of the black soldier fly oil manufacturing method of the present invention will be clearly presented in the following examples.

Please refer to shown in the first figure, the embodiment of the present invention proposes a kind of black soldier fly oil manufacturing method comprises steps S101 to S106:

Step S101, cleaning a black soldier flies with a solution, the solution is tap water or deionized water, and the black soldier flies are scalded with hot water after cleaning, and the temperature of the hot water is between 40°C and 60°C. between degrees.

In step S102, the washed black soldier flies are placed in a drying space, and the drying space has a microwave dryer, and the black soldier flies are dried into a dried worm by the microwave drying machine, and the moisture content of the dried worm is determined by In order to be 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°C and 30°C, and the drying time is between 40 and 45 minutes.

Step S103, put the dried worm into a screw oil press, after the dried worm falls into the conical helical axis of the screw oil press, it is advanced along with the rotation of the axis, through the thread spacing and the pressing cavity space. Gradually shrinking, the worm stem is squeezed by pressure and spirally extrudes a black soldier fly worm oil, and the worm stem after oil extraction is discharged from the pressing chamber. It should be noted that, after microwave drying, the black soldier fly oil squeezed out by the screw oil press has less impurities, and the dried worm particles after oil pressing are finer, which can improve the black water. The yield of horsefly oil is about 20% to 25%.

In step S104, the black soldier fly oil is placed for precipitation, and the precipitation time is between 25 and 40 minutes, and the impurities in the black soldier fly oil are separated from the black soldier fly oil through the precipitation.

Step S105, put this black soldier fly oil after the precipitation into a vacuum filter, carry out vacuum filtration to this black soldier fly oil through this vacuum filter, in this black soldier fly oil can not be precipitated. Impurities are vacuum filtered.

Step S106, put this black soldier fly oil into a supercritical extraction separator, the pressure of this supercritical extraction separator is between 14.7psi to 3600psi, and the pressurization is sequentially operated from 1500psi to 3600psi and one atmosphere. , the temperature of the supercritical extraction and separation machine is between 35 degrees Celsius to 45 degrees Celsius, and the extraction time of the supercritical extraction and separation machine is between 35 minutes and 45 minutes to obtain a purified black soldier fly oil.

It should be noted that the black soldier fly oil comprises: a fat and oil between 20 and 24 parts by weight, an amino acid between 38 and 40 parts by weight, and a part by weight between 46 and 58 of monolauric acid, and 17 to 22 parts by weight of a protease. The purified black soldier fly oil has the same composition as the black soldier fly oil, and the difference lies in that the purified black soldier fly oil is purified by supercritical extraction to improve the purity of the ingredients.

The supercritical extraction and separator extraction using the above-mentioned black soldier fly oil manufacturing method can shorten the production time, avoid the damage of the material structure of the extract due to high temperature, reduce the amount of organic solvent, and increase the productivity to 90% . It should be noted that the lauric acid of the black soldier fly oil is the raw material for the production of soaps, detergents, cosmetic surfactants and chemical fiber oils, and can be added to cosmetics, food, feed, fertilizers, plant pest control agents and animals. and aquatic product control agents.
