Problems solved by technology

[0003] Due to the fast digestion speed and large food intake of black soldier fly larvae, in the existing bioconversion process of kitchen waste, the method of feeding multiple times is adopted, that is, feeding once every two or three days, and feeding multiple times The advantage of feeding is that the food waste can be fed and digested more fully, the biomass of larvae accumulates larger, and the remaining material is relatively dry and easy to sieve. accomplish

Embodiment 1

[0017] An improved method for utilizing black soldier flies to bioconvert food waste, comprising the following steps: feeding the sorted and pulverized food waste into a mixer through a conveying device, adding bran to the mixer, the quality of the food waste and the bran The ratio is 9:1, the relative humidity is adjusted to 80%, and the treated material is obtained. Add EM bacteria according to 1% of the total mass of the treated material, and mix evenly to obtain a mixed material. Put the mixed material into the breeding tray. The size of the breeding tray is 900mm*500mm*200mm 25 kg of mixed material and 0.5 kg of black soldier fly 5-day-old larvae were added successively in each breeding tray. The thickness of the mixed material was 8 cm, and it was raised at a temperature of 28 ° C and a relative humidity of 80%. It was raised for 6 days and raised until The culture tray on the 7th day was taken out, and the mixed material in the culture tray was separated by a vibrating s...

Embodiment 2

[0019] An improved method for utilizing black soldier flies to bioconvert food waste, comprising the following steps: feeding the sorted and pulverized food waste into a mixer through a conveying device, adding bran to the mixer, the mass ratio of food waste and distiller's grains 9:1, adjust the relative humidity to 80% to obtain the treatment material, add EM bacteria according to 3% of the total mass of the treatment material, mix evenly to obtain the mixture, put the mixture into the culture tray, the size of the culture tray is 900mm*500mm*200mm, Add 25 kilograms of mixed material and 0.5 kilogram of black soldier fly 5-day-old larva successively in each culture dish, the thickness of mixed material is 8cm, raises under the condition of temperature 28 ℃, relative humidity 80%, raises 8 days, will raise to the second The 9-day culture tray was taken out, and the mixed material in the culture tray was separated by a vibrating sieve to obtain mature black soldier fly larvae a...

Embodiment 3

[0021] An improved method for utilizing black soldier flies to bioconvert food waste, comprising the following steps: feeding the sorted and pulverized food waste into a mixer through a conveying device, adding distiller's grains to the mixer, the mass ratio of food waste and bran 9:1, adjust the relative humidity to 80% to obtain the treatment material, add EM bacteria according to 1% of the total mass of the treatment material, mix evenly to obtain the mixed material, put the mixed material into the breeding tray, and the area of ​​the breeding tray is 0.4m 2 , with a height of 15 cm, 25 kg of mixed material and 0.5 kg of black soldier fly 5-day-old larvae were successively added to each breeding tray, the thickness of the mixed material was 8 cm, and they were raised at a temperature of 28°C and a relative humidity of 70% for 6 days , take out the breeding tray raised to the 7th day, and separate the mixed material in the breeding tray through a vibrating sieve to obtain mat...

Abstract

The invention provides a process for biotransformation of kitchen waste through hermetia illucens. The process includes the following steps that ingredients are added into the sorted and smashed kitchen waste, the relative humidity is adjusted, processing materials are obtained, EM bacteria are added, and a mixture is obtained after even mixing is carried out; and the mixture is paved on a cultivation disc, five-day-age larva of the hermetia illucens is added, feeding is carried out at the temperature ranging from 28 DEG C to 32 DEG C and the relative humidity ranging from 70% to 90%, and after feeding is completed, hermetia illucens mature larva and remnant materials are separated. According to the process, one-time putting of the kitchen waste can be achieved, the growth requirement of the hermetia illucens larva can be met, the processing process can be greatly simplified, and efficiency is improved.

Description

Technical field: [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for using black soldier flies to biotransform kitchen waste. Background technique: [0002] The black soldier fly (Hermitia illucens) is an insect belonging to the genus Soldierididae of the Diptera Soldieridae, also known as the bright-spotted Soldier Fly. Many biological characteristics of the black soldier fly are very suitable for the transformation of food waste, such as scavenging larvae, miscellaneous feeding habits, large food intake, strong stress resistance, overlapping life history and great elasticity, and high nutritional value of prepupa. It has migration characteristics before pupation. Therefore, in the field of research on the conversion of kitchen waste into insect protein, the black soldier fly quickly stood out from many dipteran insects and received extensive attention. [0003] Due to the fast digestion speed and large...
