Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of black soldier fly processing equipment, and in particular to a production line for screening, color sorting and vacuum packaging of dried black soldier fly larvae. Background Technology
[0002] Black soldier flies can effectively decompose kitchen waste and convert it into high-value biomass such as oil and protein. Using black soldier flies to treat kitchen waste is an environmentally friendly and economically beneficial method. During the black soldier fly breeding process, the insect excrement can be used as biological organic fertilizer. Black soldier fly larvae, due to their high protein content, can be directly fed to poultry and aquatic products or processed into feed additives to replace traditional fishmeal.
[0003] During the processing of black soldier fly larvae, the larvae need to be dried to obtain dried black soldier fly larvae. The dried black soldier fly larvae contain impurities such as broken larvae, frass, and down, so they need to be screened again.
[0004] Among them, Chinese invention patent application number 202411899435.4, entitled "A Black Soldier Fly Larvae Drying and Sorting Device and Method," specifically discloses a black soldier fly drying and sieving device. The black soldier fly larvae drying and sorting device specifically discloses the following technical solution: a black soldier fly larvae drying and sorting device, including a drying chamber, a separating device, a recovery device, and an air-blowing screening device; the drying chamber is equipped with a heating device for drying the fresh black soldier fly larvae; the separating device is connected to the outlet end of the drying chamber and includes a first conveyor belt with multiple separating plates on it. Furthermore, the separator and the first conveyor belt do not interfere with each other; the recycling device is connected to the end of the first conveyor belt to receive dried black soldier fly larvae. The recycling device includes a chain-type insect-collecting spoon device, a funnel conveyor component that docks with the chain-type insect-collecting spoon device, and a second conveyor belt located at the bottom of the funnel conveyor component. The dried black soldier fly larvae fall onto the second conveyor belt through the funnel conveyor component and are distributed at intervals on the second conveyor belt; the air-blowing screening device includes an air-blowing device and an image acquisition device. The image acquisition device is located near one end of the funnel conveyor component, and the air-blowing device is fixed to the side of the second conveyor belt. The control system controls the start of the air-blowing device based on the image acquisition information.
[0005] In the black soldier fly larvae drying and sorting device, during the sorting of dried black soldier fly larvae, an image acquisition device captures images of the larvae falling onto the second conveyor belt from the funnel conveyor. The control system processes the image information and sends corresponding signals to the air blowing device to identify and judge the color of the black soldier fly larvae. If the color is black, the black soldier fly larvae are determined to be unqualified, and the air blowing device is activated. If the color is not black, the air blowing device is not activated, and qualified black soldier fly larvae are collected.
[0006] It should be noted that the aforementioned black soldier fly larvae drying and sorting device has the following defects, specifically:
[0007] Defect 1: This black soldier fly larvae drying and sorting device can only sort dried black soldier fly larvae based on color, and cannot perform multi-level sorting of dried black soldier fly larvae by combining size and color, resulting in low sorting accuracy.
[0008] Defect 2: This black soldier fly larvae drying and sorting device can only dry and screen black soldier flies, but cannot package the screened dried black soldier flies, which means it has a relatively limited function. Utility Model Content
[0009] The purpose of this utility model is to provide a black soldier fly larvae screening, color sorting, and vacuum packaging production line to address the shortcomings of existing technologies. This black soldier fly larvae screening, color sorting, and vacuum packaging production line has a novel structural design, high sorting accuracy, and multiple functions.

[0014] When the black soldier fly larvae screening, color sorting, and vacuum packaging production line is in operation, the larvae feeding hopper supplies black soldier fly larvae to the feeding end of the first inclined conveyor. The first inclined conveyor transports the black soldier fly larvae to a reciprocating screen, which sorts the black soldier fly larvae according to their size. The larger black soldier fly larvae obtained after being sorted by the reciprocating screen fall directly to the feeding end of the second inclined conveyor. The second inclined conveyor transports the black soldier fly larvae to a color sorter, which sorts the black soldier fly larvae according to their color.

[0018] The inclined conveyor includes a conveyor belt support, on which an active conveyor shaft and a driven conveyor shaft are rotatably mounted respectively. A dry insect conveyor belt is wound between the active conveyor shaft and the driven conveyor shaft respectively. A drive motor is installed on the conveyor belt support corresponding to the active conveyor shaft, and the drive motor is drivenly connected to the active conveyor shaft.
[0019] The conveying surface of the dried worm conveyor belt is provided with several horizontal bars arranged at intervals along the extension direction of the dried worm conveyor belt. The left and right ends of the dried worm conveyor belt are respectively provided with side guards extending along the dried worm conveyor belt.

[0020] The dry insect conveyor belts of each of the inclined conveyors are arranged with a lower front and a higher back along the direction of conveying the black soldier fly larvae, and each of the conveyor belt supports is equipped with a guide wheel assembly for guiding the movement of the corresponding dry insect conveyor belt.
[0021] Compared with the prior art, the present invention has the following beneficial effects, specifically:
[0022] 1. This utility model uses a reciprocating sieve and a color sorter to screen dried black soldier fly larvae, which can sort dried black soldier fly larvae in multiple stages by combining size and color, with high sorting accuracy.
[0023] 2. This utility model can package dried black soldier fly larvae after screening using an automatic vacuum packaging machine, offering multiple functions;

Detailed Implementation
[0032] The present invention will now be described in conjunction with specific embodiments.
[0033] Example 1, as Figure 1 As shown, a production line for screening, color sorting, and vacuum packaging of dried black soldier fly larvae includes a conveying assembly and a color sorter 1.
[0034] Among them, such as Figure 1 As shown, the conveying assembly includes several inclined conveyors, which are sequentially named as first inclined conveyor 21, second inclined conveyor 22, and third inclined conveyor 23.
[0035] Furthermore, such as Figure 1 As shown, the black soldier fly larvae screening, color sorting, and vacuum packaging production line also includes a dry larvae feeding bin 3, a reciprocating screen 4, and an automatic vacuum packaging machine 5. The dry larvae feeding bin 3, the first inclined conveyor 21, the reciprocating screen 4, the second inclined conveyor 22, the color sorter 1, the third inclined conveyor 23, and the automatic vacuum packaging machine 5 are arranged sequentially along the black soldier fly larvae conveying direction.
[0036] It should be noted that during the operation of the black soldier fly larvae screening, color sorting, and vacuum packaging production line, the dried larvae feeding bin 3 supplies the dried black soldier fly larvae to the feeding end of the first inclined conveyor 21. The first inclined conveyor 21 transports the dried black soldier fly larvae to the reciprocating screen 4. The reciprocating screen 4 sorts the dried black soldier fly larvae according to their size, and the larger dried black soldier fly larvae obtained after being sorted by the reciprocating screen 4 fall directly into the feeding end of the second inclined conveyor 22. The second inclined conveyor 22 transports the dried black soldier fly larvae to the color sorter 1. The color sorter 1 sorts the dried black soldier fly larvae according to their color, and the dried black soldier fly larvae with better color obtained after being sorted by the color sorter 1 fall into the third inclined conveyor 23. The third inclined conveyor 23 transports the dried black soldier fly larvae to the automatic vacuum packaging machine 5 for vacuum packaging.
[0037] It should be emphasized that, for the black soldier fly larvae screening, color sorting, and vacuum packaging production line of this embodiment, the black soldier fly larvae are screened by a reciprocating screen 4 and a color sorter 1 respectively. The reciprocating screen 4 can screen the black soldier fly larvae according to their size, and the color sorter 1 can screen them according to their color. Therefore, the black soldier fly larvae screening, color sorting, and vacuum packaging production line of this embodiment can perform multi-stage sorting of black soldier fly larvae by combining size and color, with high sorting accuracy.
[0038] It should be further emphasized that the black soldier fly larvae screening, color sorting, and vacuum packaging production line of this embodiment can package the screened black soldier fly larvae using an automatic vacuum packaging machine 5, and has multiple functions.
[0039] In summary, the black soldier fly larvae screening, color sorting, and vacuum packaging production line of this embodiment has the advantages of novel structural design, high sorting accuracy, and diverse functions through the above structural design.
[0040] Example 2, as Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that: the dry insect feeding bin 3 includes a fixed support frame 31, and the upper end of the fixed support frame 31 is equipped with a vertically arranged feeding hopper 32. The feeding hopper 32 has a vertically penetrating inner cavity 321 inside. The upper opening of the inner cavity 321 is the feeding port, and the lower opening of the inner cavity 321 is the discharging port.
[0041] The lower end of the feeding hopper 32 is equipped with a vibrating receiving groove 33, which is formed with a receiving cavity 331 that opens toward the side of the first inclined conveyor 21. The lower end of the feeding hopper 32 extends into the receiving cavity 331 of the vibrating receiving groove 33.
[0042] A straight vibrator 34 is installed on the lower end of the fixed support frame 31 and the bottom of the vibrating receiving trough 33 is connected to the driving end of the straight vibrator 34.
[0043] In this second embodiment, the dry insect feeding bin 3 is equipped with a controller, and the direct vibrator 34 is electrically connected to the controller; during operation, the controller controls the direct vibrator 34 to operate.
[0044] In the process of feeding black soldier fly larvae into the dry larvae feeding bin 3 in this embodiment 2, the black soldier fly larvae are poured into the inner cavity 321 of the hopper through the inlet. The black soldier fly larvae in the inner cavity 321 are discharged from the outlet at the lower opening of the inner cavity 321 and enter the receiving cavity 331 of the vibrating receiving trough 33. As the vibrator 34 drives the vibrating receiving trough 33 to vibrate, the black soldier fly larvae that fall into the receiving cavity 331 of the vibrating receiving trough 33 are discharged from the opening of the receiving cavity 331. The above vibration action can make the black soldier fly larvae evenly distributed on the feeding end of the first inclined conveyor 21.
[0045] Example 3, as Figure 3 and Figure 4 As shown, the difference between this embodiment three and embodiment one is that the inclined conveyor includes a conveyor belt support, and the conveyor belt support is rotatably mounted with an active conveyor shaft and a driven conveyor shaft. A dry insect conveyor belt 25 is wound between the active conveyor shaft and the driven conveyor shaft. The conveyor belt support is equipped with a drive motor 26 corresponding to the active conveyor shaft, and the drive motor 26 is drivenly connected to the active conveyor shaft.
[0046] The conveying surface of the dried worm conveyor belt 25 is provided with several horizontal strips 27 arranged at intervals along the extension direction of the dried worm conveyor belt 25. The left and right ends of the dried worm conveyor belt 25 are respectively provided with side rails 28 extending along the dried worm conveyor belt 25. The horizontal strips 27, side rails 28 and dried worm conveyor belt 25 are an integral structure.
[0047] During the process of conveying dried black soldier fly larvae on each inclined conveyor, the drive motor 26 drives the active conveyor shaft to rotate, and the active conveyor shaft cooperates with the driven conveyor shaft to drive the dried larvae conveyor belt 25 to move.
[0048] For black soldier fly larvae that fall onto the conveyor surface of the dry larvae conveyor belt 25, the crossbar 27, which moves synchronously with the dry larvae conveyor belt 25, is used to scrape the black soldier fly larvae to ensure the stability of the black soldier fly larvae conveying; the side guards 28 located on the left and right ends of the crossbar 27 can effectively prevent the black soldier fly larvae from falling off, thereby further ensuring the stability of the black soldier fly larvae conveying.
[0049] Example 4, as Figure 3 and Figure 4 As shown, the difference between this embodiment four and embodiment one is that the dry insect conveyor belts 25 of each climbing conveyor are arranged with the front lower and the back higher along the direction of conveying black soldier fly dry insects, and each conveyor belt support is equipped with a guide wheel group 29 for guiding the movement of the corresponding dry insect conveyor belt 25.
[0050] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
