Embodiment 1
[0018] Sorting paper towels, toothpicks and other sundries in 2 kg of kitchen waste; mixing them with rapeseed meal at a mass ratio of about 1:1.5, so that the mass percentage of the water content of the mixture reaches about 40%; The mixture of garbage and rapeseed meal was crushed until the particle size was below 3 mm; the mixture was sterilized at 121 °C for 15 minutes, cooled to room temperature, and inoculated with activated Bacillus licheniformis (Bacillus licheniformis) at a ratio of 10% (v / w). ) culture medium, fermented at 37 °C for 1 day; then sterilized at 121 °C for 15 minutes, cooled to room temperature and inoculated with activated Saccharomyces cerevisiae (Saccharomyces cerevisiae) culture medium at a ratio of 5% (v / w), at 28 °C Continue the fermentation for 5 days; add 0.5 kg of the fermented mixture to 0.5 kg of black soldier fly larvae (Hermetia illucens L.), and raise them at 27 °C. The process lasts for about 10 days. When the black soldier fly larvae beco...
Embodiment 2
[0020] Sorting paper towels, toothpicks and other debris from 5 kg of kitchen waste; mixing them with cottonseed meal at a mass ratio of about 1:1, so that the mass percentage of the water content of the mixture reaches about 50%; kitchen waste and The mixture of cottonseed meal is crushed to a particle size below 3 mm; the mixture is sterilized at 121 °C for 15 minutes, cooled to room temperature, and inoculated with activated Bacillus licheniformis (Bacillus licheniformis) culture solution at a ratio of 2% (v / w) , fermented at 37°C for 3 days; then sterilized at 121°C for 15 minutes, cooled to room temperature, inoculated with activated Saccharomyces cerevisiae culture medium at a ratio of 10% (v / w), and continued fermentation at 28°C for 2 days; 2.5 kg of the fermented mixture was added to 0.5 kg of black soldier fly larvae (Hermetia illucens L.), and reared at 27 °C. During the feeding process, the fermentation product was appropriately added depending on the feeding situat...
Embodiment 3
[0022] Sorting paper towels, toothpicks and other debris from 3 kg of kitchen waste; mixing them with soybean meal at a mass ratio of about 1:0.6 to make the water content of the mixture reach about 60% by mass; separating the kitchen waste and soybean meal The mixture was crushed to a particle size below 3 mm; the mixture was sterilized at 121 °C for 15 minutes, cooled to room temperature, and then inoculated with activated Bacillus licheniformis (Bacillus licheniformis) culture solution at a ratio of 6% (v / w). Ferment at 37°C for 2 days; then sterilize at 121°C for 15 minutes, cool to room temperature and inoculate the activated Saccharomyces cerevisiae culture solution at a ratio of 8% (v / w), and continue to ferment at 28°C for 3 days; Add 1 kg of the fermented mixture to 0.5 kg of black soldier fly larvae (Hermetia illucens L.), and raise them at 27 °C. During the feeding process, the fermentation products are added appropriately depending on the feeding situation of the bl...
