[0023] It's important to note that the potential value of food waste, a valuable biomass resource rich in organic matter and diverse nutrients, has long been significantly underestimated. In particular, its inherent abundance of high-quality nutrients, such as protein and fat, if utilized through scientific and efficient conversion pathways, could not only significantly alleviate the feed resource constraints faced by the livestock, poultry, and aquaculture industries but also significantly promote the vigorous development of a circular economy in agriculture. Against this backdrop, the black soldier fly, with its remarkable ability to decompose organic waste, has become a rising star in the field of food waste resource utilization. With their astonishing growth rate, wide-ranging dietary adaptability, and high conversion efficiency, black soldier fly larvae demonstrate a highly efficient ingestion and conversion of organic matter from food waste. They can consume large quantities of organic matter from food waste, transforming it into high-quality protein and fat through their own physiological mechanisms, thus providing an ideal source of supplemental protein feed for livestock, poultry, and aquaculture. This characteristic not only opens up new avenues for food waste treatment but also transforms waste into a high-value resource, demonstrating the unlimited potential of resource recycling. Therefore, large-scale breeding of black soldier fly larvae to treat food waste and convert it into resources beneficial to agricultural production has become a promising sustainable development practice;
[0024] In this embodiment, the processing barrel 1 serves as the core container of the entire device, and is used to accommodate the food waste to be processed. The organic matter and nutrients rich in the food waste provide a rich food source for the black soldier fly larvae; the removable filter bucket 2 is arranged inside the processing barrel 1, and its design allows easy lifting and disassembly, which is convenient for cleaning and maintenance. The main function of the filter bucket 2 is to hold and drain excess water from food waste, and at the same time serve as a breeding environment for black soldier fly larvae, ensuring that the larvae feed under suitable humidity conditions; the filter cover 3 is installed under the filter bucket 2 to play a supporting role, preventing the lower end of the filter bucket 2 from directly contacting and immersing in the accumulated water at the bottom of the treatment barrel 1, and keeping the larvae breeding environment dry and hygienic; the barrel cover 4 covers the mouth of the treatment barrel 1, and a small gap is left between its inner side and the outer side of the mouth of the treatment barrel 1. This design cleverly provides a crawling channel for the black soldier fly larvae; the recess 5 is opened on the side wall of the mouth of the treatment barrel 1, serving as an exit for the black soldier fly larvae to crawl out. This design allows the larvae to naturally migrate from the inside of the treatment barrel to the external insect collecting shell 6; the insect collecting shell 6 is fixed on the outer wall of the treatment barrel 1, and is used to receive and collect the insects from the recess. The black soldier fly larvae that crawl out of the container 5 are collected in the first and second outlets 7 and 8 opened on the insect shell 6, and the larvae crawl out of the first outlet 7 and fall into the feeding trough for livestock and poultry to eat; an auxiliary mechanism is arranged inside the processing barrel 1, which is used to assist the black soldier fly larvae to crawl out of the recess 5 more smoothly; through the black soldier fly larvae's efficient engulfment and transformation of food waste, the waste is converted into biomass rich in high-quality protein and fat, providing an ideal source of supplementary protein feed for livestock, poultry and aquaculture, and realizing the resource utilization of waste; the transformation products of the black soldier fly larvae effectively alleviate the feed resource shortage faced by the livestock, poultry and aquaculture industries, reduce feed costs, improve breeding efficiency, promote the development of agricultural circular economy, and realize the recycling of resources and the reduction, harmlessness and resource utilization of waste.
[0025] In a further preferred embodiment of the present utility model, the auxiliary mechanism includes: a climbing trough plate 11 arranged in the processing barrel 1, the inlet end of the climbing trough plate 11 extends into the filter bucket 2, and the outlet end of the climbing trough plate 11 extends into the recess 5; a positioning rod 13 fixed on the climbing trough plate 11, used to limit the climbing trough plate 11; a limiting sleeve 12 mounted on the positioning rod 13, and the top of the limiting sleeve 12 is fixedly connected to the barrel cover 4.
[0026] In this embodiment, a specially designed auxiliary mechanism optimizes the larvae's crawling path from the filter hopper to the exterior of the treatment barrel, ensuring a smooth and efficient exit. A crawling trough 11 is positioned within the treatment barrel 1. Its ingenious design extends its inlet end into the filter hopper 2, while its outlet end points directly into and extends into the recess 5. This layout provides a clear, unobstructed crawling path for the black soldier fly larvae, allowing them to smoothly migrate along the crawling trough from the filter hopper 2 to the insect collection housing 6 outside the treatment barrel 1. A positioning rod 13 is securely fastened to the crawling trough 11, serving primarily as a stopper to ensure the trough 11 remains stable within the treatment barrel 1. The rod 13 is cleverly mounted on the positioning rod 13, with its top securely connected to the barrel lid 4. This design not only further enhances the stability of the crawling trough, but also, through the support provided by the barrel lid 4, makes the entire auxiliary mechanism more secure and reliable.
[0027] In a further preferred embodiment of the present invention, the first insect outlet 7 is fixedly connected to a first guide pipe 9 for guiding the black soldier fly larvae to the feeding trough for feeding livestock and poultry, and the second insect outlet 8 is fixedly connected to a second guide pipe 10 for connecting to the pupation equipment.
[0028] In this embodiment, in order to further improve the resource utilization efficiency and convenience of black soldier fly larvae after processing food waste, a first guide pipe 9 and a second guide pipe 10 are fixedly connected to the first insect outlet 7 and the second insect outlet 8 respectively. This design not only optimizes the subsequent processing process of the larvae, but also improves the automation and integration level of the entire system. The first guide pipe 9 is fixedly connected to the first insect outlet 7. Its main function is to directly guide the black soldier fly larvae discharged from the insect collecting shell 6 and reaching the mature stage that can be used to feed livestock and poultry to the trough or other feeding equipment. This design reduces the steps of manual collection and transportation of larvae, improves feeding efficiency, and also reduces the risk of damage or escape that the larvae may suffer during the transfer process; the second guide pipe 10 is fixedly connected to the second insect outlet 8, and its purpose is to connect to the pupation equipment. After the larvae grow to a certain stage, some larvae will enter the pupation stage, at which time they need to pass through a specific environment for metamorphosis. The second guide tube 10 efficiently and smoothly transports these larvae to the pupation equipment for subsequent adult rearing or resource utilization. Directly transporting the larvae to the feeding equipment via the first guide tube 9 ensures immediate larval resource utilization, avoiding nutritional loss or quality degradation caused by prolonged storage or transportation. Furthermore, the design of the second guide tube 10 ensures that the pupated larvae can smoothly enter the next growth stage, ensuring subsequent adult rearing or resource utilization. This simplifies the subsequent larval processing process, reduces manual intervention and operational steps, and improves the automation and integration of the entire system.

This water may contain certain pollutants or nutrients, so it needs to be discharged in time to avoid affecting subsequent treatment; the setting of the drain pipe 14 provides an effective way to solve this problem; the valve 15 is installed on the drain pipe 14 to control the discharge of water flow. By opening or closing the valve 15, the user can adjust the discharge timing and discharge amount according to actual needs, thereby achieving precise management of the water in the treatment barrel 1.
[0031] In a further preferred embodiment of the present invention, protrusions 16 are symmetrically fixed on the inner wall of the processing barrel 1 for supporting the filter bucket 2 and limiting its position.
[0032] In this embodiment, to enhance the stability and positioning accuracy of the filter hopper within the treatment barrel, protrusions 16 are symmetrically fixed to the inner wall of the treatment barrel 1. This design not only enhances the load-bearing capacity of the filter hopper but also effectively limits its position, preventing it from shaking or shifting during the treatment process.
[0033] In a further preferred embodiment of the present invention, handles are symmetrically fixedly mounted on the barrel cover 4 for people to grasp, and a rubber sleeve is provided on the handle.
[0034] In this embodiment, in order to improve the convenience and comfort of the operator, handles are symmetrically fixedly installed on the barrel cover 4, and rubber sleeves are provided on the handles to improve the comfort and anti-slip performance of holding.
[0035] In a further preferred embodiment of the present invention, support blocks are symmetrically fixedly installed on the bottom of the processing barrel 1, and the second insect outlet 8 is designed to be inclined.
[0036] In this embodiment, in order to improve the stability of the processing barrel 1 and the smoothness of the discharge of larvae from the second insect outlet 8, the following two improvement measures are specially taken: First, support blocks are symmetrically fixedly installed at the bottom of the processing barrel 1.

[0037] To sum up, through the coordinated use of the filter basket 2 and the filter cover 3, the excess water in the food waste is effectively drained out, the breeding environment of the black soldier fly larvae is kept dry, and the larvae are ensured to eat and grow efficiently under suitable humidity. The black soldier fly larvae efficiently devour and transform the food waste, converting the waste into biomass rich in high-quality protein and fat, providing an ideal source of supplementary protein feed for livestock, poultry and aquaculture, and realizing the resource utilization of waste; the synergistic effect of the climbing trough plate 11 and the positioning rod 13 provides an unobstructed crawling channel for the black soldier fly larvae, ensuring that the larvae can smoothly migrate to the insect collection shell 6 outside the treatment barrel, thereby improving the efficiency of larval transformation and collection; the intelligent guiding mechanism of the first guide pipe 9 and the second guide pipe 10 realizes the immediate utilization of larval resources and the efficient transportation of pupated larvae, reduces manual intervention, and improves the degree of automation and integration; the precise discharge control of the drain pipe 14 and the valve 15 effectively manages the accumulated water in the treatment barrel, avoids negative impact on the treatment process, and recycles the nutrients in the water.
