Problems solved by technology

[0017] Attempts to use black soldier flies to treat agricultural solid organic wastes are actively being carried out in the United States, South Korea, and Sweden, but most of them are still in the laboratory stage, and there are no successful large-scale treatment applications so far

Embodiment 1

[0027] Waste meat such as dead pigs and cows transported from large-scale farms, after large-scale mechanical processing, is crushed into minced meat and bones with a particle size of 0.5-5cm, and is dispersed to different processing pools by small forklifts. Each processing pool Put the 3rd instar larvae of the black soldier fly with a total weight of 500kg and the base material in advance. The weight ratio of the larvae to the base material is 1:1. The formula of the base material is: every 58 ml of probiotic culture with pH8. Liquid (lactic acid bacteria) mixed with 16 grams of mulberry leaf powder, 34 grams of corn flour and 2 grams of yeast. The mass ratio of broken minced meat and bones to the total mass of black soldier fly larvae and base material is 2:1, and the temperature is controlled at 22-28°C. The thickness of the layer does not exceed 10 cm. Generally, black soldier flies can complete the biotransformation of minced meat and bones within 24 hours. Feed again ...

Embodiment 2

[0029] For poultry animal carcasses with feathers, the direct use of crushing method for pretreatment will produce a large amount of pollutants such as hairs, which is not good for the equipment. Put into the treatment pool again, and the specific treatment steps are the same as in Example 1. Although the biotransformation by black soldier flies is not broken, because the animal carcasses have been softened and matured at this time, high-efficiency disposal can also be achieved.

Abstract

The invention discloses a method for treating waste meat by hermetia illucens larvae. The hermetia illucens larvae are saprophagous insects and particularly like eating animal carcasses. Through research, the inventor finds out that the efficiency of treating the animal carcasses by the hermetia illucens larvae is related to the food surface area, the environment temperature, the pH value, the carbon nitrogen ratio and the bulking thickness, so that before the treatment, the waste meat is crushed to reach the grain diameter of 0.5-5 cm, the environment temperature is controlled to 22-28 DEG C, the pH value is 8.0-8.3 (alkalescence), a carbon source (corn flour) is properly added and the bulking thickness is not more than 10cm; under the conditions, third-stage hermetia illucens larvae can finish the biological conversion of the animal carcasses within 24 hours under the weight ratio of 1 to 2 so as to realize the treatment efficiency similar with that of physical treatment; a final product of treatment is disinfected and sterilized at a high temperature and can be processed into a feed raw material with a high additional value, and thus a resource utilization target is realized.

Description

Technical field: [0001] The invention belongs to the field of waste meat treatment, and in particular relates to a method for using black soldier fly larvae to dispose of waste meat. Background technique: [0002] The black soldier fly Hermetia illucens is an insect of the Diptera Soldier Fly family. Its English name is Black Soldier Fly, also known as the bright flat-horned soldier fly. The larvae are scavengers and eat a wide range of food. It is commonly found near pig pens and chicken houses in rural areas, and eats fresh pig manure and chicken manure. [0003] Black soldier flies are native to the tropical savannahs of South America, and then spread to North America. After World War II, with the extensive transportation and flow of personnel and materials, black soldier flies quickly spread to most areas in temperate, subtropical and tropical regions. There are specimen records or research documents in Hainan, Guangdong, Guangxi, Fujian, Hebei, Sichuan, Hong Kong, and ...
