Problems solved by technology

However, the pressing method has the disadvantages of low oil yield, high labor intensity, and low production efficiency, and the protein denaturation in the meal is serious during the oil pressing process.
Leaching method is a widely used method of oil production. It is based on the principle of solid-liquid extraction, selects an organic solvent that can dissolve fat, and extracts the fat in the oil through contact with the oil—soaking or spraying. One method, the leaching method, has a high oil yield, and the temperature of the leaching process is relatively low, but its disadvantage is that the solvent used is flammable, explosive, and has certain toxicity.
Both of the above two traditional processes focus on the extraction of fat, and the deep processing and reuse of protein is severely limited due to the degree of protein denaturation of the cake with high protein content after oil extraction.

Embodiment 1

[0023] A method for separating edible insect soldier flies into organic waste and insect matter, the steps of which are:

[0024] Soldier Fly Larvae Cultivation: Soldier Fly Larvae Cultivation: The Soldier Fly Bright Spot is a Wuhan Strain, which was domesticated and bred from the wild population in Wuhan in this experiment. The method of collecting eggs and raising larvae of the Wuhan Strain of Soldier Fly Bright Spot According to the approved patent (A domestication and breeding method and application of a Wuhan strain of flat horned soldier fly, CN201110191867.6). Transfer the mixture of larvae and feed to a beaker, and use a small spoon to gently scoop off the rest of the feed on the surface. Soldier fly larvae have the habit of clustering and photophobia, and they will automatically drill down to clean out relatively clean larvae; the larvae counting method first mixes the separated larvae thoroughly, and randomly picks more than 200 larvae for weighing , counting the to...

Embodiment 2

[0040] Embodiment 2: Taking Tenebrio molitor as an example to transform crop stalk oil and protein feed:

[0041] The most important thing for raising Tenebrio molitor is to have species: adult larvae, pupae, and adults can all be used as species. Breeding to different insect stages, according to the breeding technology of Tenebrio molitor, carefully select pupae and adults, and sieve eggs, so that each insect stage can reproduce synchronously. After careful selection and breeding, all stages of insects can be used as seed insects for reproduction, but it is better to use adult larvae as seed insects. The growth rate of larvae and the length of the larval stage depend on temperature, humidity and feed. In general, the higher the temperature, the shorter the juvenile period, the specific temperature is 25-28°C, and the relative humidity is 60-70%.

[0042] Tenebrio molitor has strong adaptability, easy to master breeding technology, both industrial farming and decentralized b...

Embodiment 3

[0050] Embodiment 3: prepare crude fat and protein by transforming the insect body of livestock and poultry manure with housefly larvae:

[0051] The most important thing about housefly larvae is that there are seed worms: mature larvae, pupae, and adults can all be used as seed worms. Adult flies were fed with a mixture of milk powder:brown sugar:water (1:1:5), and the drinking water was changed every day. The fresh pig manure collected on the day and the compound feed were prepared (10:1) to form the egg collection information object and the oviposition bed, and the eggs collected every 24 hours were inoculated in the fresh pig manure collected on the day. Breed to different insect stages, according to the cultivation technology of housefly larvae, carefully select pupae and adults, remove diseased insects, sieve eggs, and make each insect stage reproduce synchronously. The water content of livestock and poultry feces is about 70-81%. After culturing at room temperature (24...

Abstract

The invention discloses a material separation method for conversion from edible insect bodies to organic waste, which is specifically implemented by carrying out drying and vacuum drying on insect bodies subjected to waste conversion, especially, microwave drying is adopted, live insects are directly laid in a microwave drying device, and the lying thickness of the live insects is 1-5 cm, and the time is controlled at 2-10 minutes. Dried stratiomyiid bodies are crushed, and then stratiomyiid oil is extracted respectively by using traditional methods such as a cold-maceration method, a soxhlet extraction method, an ultrasonic method and a subcritical method so as to obtained separated crude oil and insect meal. The method is easy to perform and convenient to operate, thermosensitive substances in extracted oil are not damaged, bright in color and low in production cost, have no pollution, and can be used for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and more specifically relates to a method for separating edible insects from organic wastes, which is suitable for the process of treating organic wastes and provides fat and protein feed for insects. Use insect larvae such as soldier flies, houseflies, Tenebrio molitors, and hemp flies to process organic waste and turn them into organic fertilizers. At the same time, insects are extracted from oil to obtain protein feed. Background technique [0002] Environmental pollution and resource shortage are severe challenges facing mankind today. The more the economy develops, the more energy is consumed. Energy, resource and environmental issues have become the main bottleneck restricting the sustainable development of social economy. my country produces a large amount of agricultural organic waste every year, which cannot be used reasonably and effectively, and causes serious polluti...
