Description

TECHNICAL FIELD

[0001] The application relates to the technical field of feed preparation equipment, and in particular to a system for preparing a mealworm feed formula based on fermented kitchen waste solid residues. BACKGROUND

[0002] At present, the solid residues of kitchen waste oil extraction have certain "food properties", and are rich in crude protein, crude fat, amino acids and fatty acids, and have high nutritional value. However, due to the homology safety hazard, the solid residues cannot be directly made into feed to feed livestock and poultry, and the three-phase solid residues must be first converted into feed raw materials through synergistic fermentation technology by using the growth and metabolism of microorganisms.

[0003] Insects are invertebrate arthropods, and in nature, as a kind of low-level decomposer, insects need kitchen waste as their own nutrients, and after feeding, digestion and absorption, the insects reorganize the nutrients such as insect protein. At the same time, insects have a perfect digestive system and antibacterial system, and many studies have found that by feeding insects with pathogenic attack, the pathogen detection from the surface, inside and excrement of the insects is all negative. Therefore, it can be known that the pathogenic bacteria are completely killed after being digested and absorbed by the insects.

[0004] At present, the mealworm breeding is mainly divided into three categories. One is conventional breeding, and the feed formula mainly includes wheat bran, rice bran and pumpkin; the second is to use the saprophagy of mealworms to process kitchen waste, and research has found that the content of crude protein and crude fat in mealworms with 30% pork formula feed is significantly improved; and the third is to use mealworms to process livestock and poultry manure, but the manure can only be added in a small proportion, otherwise the growth of mealworms will be inhibited.

[0005] In the prior art, the solid residues of kitchen waste after water leaching and oil removal are directly used as feed raw materials to feed mealworms, or mixed with wheat bran and distiller's grains. Kitchen waste is prone to spoilage, breeding of bacteria and contains toxins, and directly feeding mealworms with the kitchen waste as feed has certain biological safety risks.

[0006] And the patent document with the publication number CN117084219B discloses a method for breeding mealworms by using kitchen waste distiller's grains. The method directly feeds the mealworms with the kitchen waste after water leaching and the distiller's grains mixed together, and the kitchen waste distiller's grains are biologically treated by feeding mealworm larvae to achieve the purpose of resource utilization. However, the biggest problem of this method is that it is not easy to keep fresh, and it will produce a foul odor in summer, and the breeding environment is very poor.

[0007] Meanwhile, the patent document with the publication number CN105558440B discloses a kind of based on organic garbage fermentation residue's yellow mealworm and black soldier fly feed.The feed includes the following components: kitchen waste fermentation residue 30~40%, agricultural and forestry waste fermentation residue 10~35%, wheat bran 8~25%, soybean meal 5~15%, sweet potato vine powder 4~6%, spilanthes 1.5~5%, honeysuckle powder 0.5~3%, feed compound vitamin 0.5~3%, Bacillus subtilis probiotics 0.1-5%.The feed is made of organic garbage fermentation residue as main raw material, supplemented with Chinese herbal medicine and probiotics, suitable for yellow mealworm larvae growth and reproduction, but formula is complex, part of material is not easy to get, and kitchen waste accounts for only 30~40%, and the reduction and resource utilization rate is limited.

[0008] Therefore, a system for preparing yellow mealworm feed formula based on fermentation kitchen waste solid residue is urgently needed to solve the above problems. Utility model content
