Description

Technical Field

[0001] The utility model belongs to the technical field of black soldier fly breeding, in particular to an adjustable black soldier fly larvae quantitative dosing device. Background Art

[0002] On the one hand, the continued growth of the global population and the constant pursuit of a higher quality of life are placing higher demands on the quality and quantity of the current food system. However, the overexploitation of the natural resources that food production relies on has become a constraint on its further development. On the other hand, our production and daily activities generate a large amount of organic waste every year. Improper treatment and disposal not only pollutes the environment but also represents a huge waste of resources.

[0003] Therefore, biotransformation, represented by black soldier fly farming, can achieve high-value utilization of low-value organic waste. The produced insect products can be used as feed for animals and aquaculture, and the insect feces can be further processed into organic fertilizer for agricultural planting, thus realizing the transformation of organic waste into feed, which has received high attention worldwide.

[0004] With the continuous development of the black soldier fly aquaculture industry, modular three-dimensional aquaculture models are gaining increasing attention. This model uses standard containers as black soldier fly aquaculture rooms. By installing three-dimensional aquaculture racks within the containers, black soldier fly larvae can be reared at high densities, increasing output per unit area and reducing land use. This modular three-dimensional aquaculture model is particularly suitable for small and medium-sized black soldier fly aquaculture projects, allowing for efficient deployment and flexible configuration. Insect and feed placement are two key operations in black soldier fly aquaculture. Accurately controlling the insect-to-feed ratio, which is required to add aquaculture slurry and black soldier fly larvae to standardized aquaculture feed boxes, significantly impacts the yield of black soldier fly products. Large variations in the feed ratios used in different aquaculture feed boxes can lead to asynchronous growth of black soldier fly larvae in different feed boxes. By the end of the aquaculture cycle, some larvae in some boxes are still in the growth stage while others have already entered the pupation stage, compromising the harvest of larvae.

[0005] Due to the large overall feed volume for aquaculture (typically over 10 kg per feed bin), current feeding equipment is relatively mature and can accurately dosing. However, accurate larvae placement is more challenging, especially for small and medium-sized aquaculture projects. High-precision equipment is required, but the market penetration of such equipment is still low. Furthermore, the high cost of such equipment increases project investment and requires high operation, hindering project implementation. Therefore, finding a convenient, fast, accurate, and cost-effective way to manually add black soldier fly larvae to aquaculture feed bins is crucial. Utility Model Content
