Abstract
Description
Technical Field
[0001] The invention relates to the technical field of black soldier fly larvae treatment, and more particularly to a black soldier fly larvae inactivation and solar energy drying device. Background Art
[0002] Black soldier fly larvae are a potential resource insect, which are widely used in biodiesel, pharmaceutical cosmetics, scientific research, food additives, etc. after drying. Fresh black soldier fly larvae have high water content and are easily damaged and rotten. Therefore, in order to facilitate the transportation and storage of black soldier flies, the live larvae of black soldier flies need to be inactivated and then further dried to remove the water in their bodies to extend the storage time.
[0003] Most of the existing black soldier fly larvae inactivation devices use high-temperature steam inactivation or electric heating inactivation to inactivate black soldier fly larvae. In the high-temperature steam inactivation method, the steam cooling and liquefaction will increase the water content of the black soldier fly larvae, which will prolong the time required for the subsequent drying process; in the electric heating inactivation method, the black soldier fly larvae are easily carbonized due to contact with the metal material at too high a temperature during the inactivation process. The carbonization of the black soldier fly larvae will not only affect the subsequent drying process, but also cause the structure of the protein in the black soldier fly larvae to be destroyed and denatured, resulting in the loss of its original functions and characteristics, so that its properties when used in biodiesel, pharmaceutical cosmetics, scientific research, food additives, etc. do not meet the requirements, and ultimately damage the quality of the finished product.
[0004] At the same time, when the black soldier fly larvae are inactivated, they will struggle or escape when exposed to heat. During the struggling process, the black soldier fly larvae are prone to stacking, resulting in uneven inactivation. However, extending the inactivation time will increase the probability of carbonization of the black soldier fly larvae. Summary of the invention
[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a black soldier fly larvae inactivation and solar energy drying device that can effectively avoid uneven inactivation caused by stacking due to the struggle of black soldier fly larvae, and carbonization caused by contact with ultra-high temperature metal during the inactivation process, which leads to denaturation of protein in the finished product after the black soldier fly larvae are dried.

The hot water completes circulation inside the water bath chamber and completes heat exchange with the inner shell body. After the temperature inside the inner shell body rises, it can continue to be discharged from the upper part of the water bath chamber under the action of the water pump and finally flow through the water outlet pipe to complete discharge.

[0020] The beneficial effects of the present invention are:
[0021] 1. The hot water is controlled by a water pump to enter the water bath cavity between the outer shell and the inner shell through the water inlet pipe. The hot water is circulated in the water bath cavity to exchange heat with the inner shell, thereby heating the inner shell in a water bath. The black soldier fly larvae in the inner shell are inactivated by water bath heating. The maximum inactivation temperature is 100°C, which is much lower than the protein denaturation carbonization temperature of 150-170°C, thereby effectively avoiding the carbonization of the black soldier fly larvae during the inactivation process and ensuring the quality of the inactivated and dried black soldier fly larvae.
[0022] 2. The black soldier fly larvae enter the water bath cylinder in a dispersed manner from the channel formed inside the feed grid, ensuring that the black soldier fly larvae can be evenly dispersed for inactivation. During the inactivation process, the spiral arc plates arranged in sections along the vertical direction fix the struggling area of the black soldier fly larvae.

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basics of the present invention in an illustrative manner, so it only shows the composition related to the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0044] Example 1, please refer to Figure 1-3 and Figure 6 , including a mounting base 1, an inactivation cartridge assembly 3 and a water inlet assembly 4, wherein the inactivation cartridge assembly 3 and the water inlet assembly 4 are mounted on the top of the mounting base 1, and the water inlet assembly 4 is arranged on one side of the inactivation cartridge assembly 3. Hot water can enter the inactivation cartridge assembly 3 through the water inlet assembly 4, and the temperature generated by the hot water circulation is used to inactivate the black soldier fly larvae in the inactivation cartridge assembly 3.
[0045] Please refer to Figure 1-3 and Figure 6 , the inactivation cylinder assembly 3 includes a water bath cylinder 32, a water bath cylinder cover 31 arranged at the top of the water bath cylinder 32, and a lower silo 33 arranged at the bottom of the water bath cylinder 32. The water bath cylinder 32 is arranged as a cylindrical structure, and a support leg is arranged at the bottom of the water bath cylinder 32, which is installed on the top of the mounting base 1 through the support leg. The water bath cylinder 32 includes an outer shell 321 and an inner shell 322 arranged coaxially, and the diameter of the outer shell 321 is larger than the diameter of the inner shell 322. The tops of the outer shell 321 and the inner shell 322 are connected to the bottom of the water bath cylinder cover 31, and the water bath cylinder cover 31 is arranged to be a disc structure whose diameter is adapted to the diameter of the outer shell 321. A water bath chamber 323 is arranged between the outer shell 321 and the inner shell 322, and the water bath chamber 32 becomes a sealed chamber arranged around the inner shell 322 through the connection of the outer shell 321 and the inner shell 322 with the water bath cylinder cover 31.
[0046] Please refer to Figure 1-3 and Figure 6 The lower feed bin 33 is configured as a conical structure with a larger top and a smaller bottom, and the outer shell 321, the inner shell 322 and the lower feed bin 33 are coaxially configured. The top diameter of the lower feed bin 33 is adapted to the diameter of the inner shell 322, so that the interior of the lower feed bin 33 is connected to the interior of the inner shell 322, and the black soldier fly larvae in the inner shell 322 can enter the lower feed bin 33 from the inner shell 322 after being inactivated. The lower feed bin 33 is provided with a discharge port 34 at the center of its bottom, and the discharge port 34 is configured as a hollow cylindrical structure, and the interior is connected to the interior of the lower feed bin 33. The inactivated black soldier fly larvae can pass through the lower feed bin 33 and enter the discharge port 34 to complete the discharge, thereby entering the next drying process.
[0047] Please refer to Figure 1-3The water inlet assembly 4 includes a water inlet pipeline 41 and a water outlet pipeline 42 that are arranged through the outer shell 321. The water inlet pipeline 41 is arranged at the lower part of the side wall of the outer shell 321, and the water outlet pipeline 42 is arranged at the upper part of the side wall of the outer shell 321. The water inlet pipeline 41 and the water outlet pipeline 42 are respectively connected to the inside of the water bath chamber 323. The end of the water inlet pipeline 41 away from the outer shell 321 is connected to a water pump 43, and the end of the water outlet pipeline 42 away from the outer shell 321 is connected to a water pump 43, and the water pump 43 is respectively connected to the water inlet pipeline 41 and the water outlet pipeline 42. The water pump 43 can drive the hot water to flow inside the water inlet pipe 41, and enter the water bath chamber 323 from the lower part of the water bath chamber 323. The hot water circulates inside the water bath chamber 323 and completes heat exchange with the inner shell 322, so that the inside of the inner shell 322 is heated up. Then, the hot water can continue to be discharged from the upper part of the water bath chamber 323 under the action of the water pump 43, and finally flow through the water outlet pipe 42 to complete the discharge.
[0048] Specifically, the water pump 43 controls hot water to enter the water bath chamber 323 between the outer shell 321 and the inner shell 322 through the water inlet pipe 41, and the hot water is circulated inside the water bath chamber 323 to exchange heat with the inner shell 322, thereby heating the inner shell 322 with a water bath, and the black soldier fly larvae inside the inner shell 322 are inactivated by water bath heating. The maximum inactivation temperature is 100°C, which is much lower than the protein denaturation carbonization temperature of 150-170°C, thereby effectively avoiding the carbonization of the black soldier fly larvae during the inactivation process and ensuring the quality of the inactivated and dried black soldier fly larvae.
[0049] In summary, the water inlet assembly 4 can be used to heat the inner shell 322 by circulating hot water in the water bath chamber 323, but the black soldier fly larvae will struggle when heated during inactivation, and will accumulate during the struggle, resulting in uneven inactivation, and will also extend the time required for inactivation and increase the probability of carbonization of the black soldier fly larvae. On this basis, the present application is also provided with a feed assembly 2 and a material leveling assembly 5, so that the black soldier fly larvae can be dispersed into the water bath cylinder 32 for inactivation, and ensure uniform contact during the inactivation process.
[0050] Please refer to Figure 1-5, a feed assembly 2 is installed on the top of the inactivation cylinder assembly 3, and the feed assembly 2 includes a feed bin 22 installed on the top of the water bath cylinder cover 31 and a feed grid 23 arranged inside the feed bin 22. The feed bin 22 is set to a conical structure of upper and lower sizes, and its side wall is provided with a baffle, which can prevent the black soldier fly larvae from escaping during the feeding process. A feed bracket 21 is provided on the outer wall of the feed bin 22, and the feed bracket 21 is installed on the top of the water bath cylinder cover 31, and the connection between the feed bin 22 and the water bath cylinder cover 31 is realized through the feed bracket 21. The feed grid 23 is set to a mesh structure and is arranged in contact with the inner wall of the feed bin 22. A feed port 24 is provided at the bottom of the feed bin 22, and the feed port 24 is arranged through the water bath cylinder cover 31. The feed grid 23 extends in the vertical direction inside the feed bin 22, and the black soldier fly larvae can reach the feed port 24 through the feed grid 23, and finally enter the water bath cylinder 32 for inactivation treatment. The black soldier fly larvae are transported and fed by utilizing the channel formed inside the feed grid 23, so that the black soldier fly larvae are kept in a dispersed state before entering the water bath cylinder 32, so as to facilitate subsequent uniform inactivation.
[0051] Please refer to Figure 6 , a material leveling assembly 5 is arranged inside the inner shell 322, and the material leveling assembly 5 includes a driving motor 51 installed at the bottom of the water bath cover 31. A material leveling disk 52 is arranged at the bottom of the driving motor 51, and the material leveling disk 52 is arranged as a disc structure, and the output end of the driving motor 51 is arranged through the material leveling disk 52. A material leveling shaft 53 is connected to the output end of the driving motor 51, and the material leveling shaft 53 is arranged in the vertical direction and coaxially with the inner shell 322. A spiral arc plate 54 is spirally arranged on the outer wall of the material leveling shaft 53 in the vertical direction, and the width of the spiral arc plate 54 is adapted to the diameter of the inner shell 322. The driving motor 51 can drive the material leveling shaft 53 to rotate, and the spiral arc plate 54 can be synchronously driven to rotate during the rotation of the material leveling shaft 53. After the black soldier fly larvae are dispersed into the water bath cylinder 32 , they pass through the gaps between the material mixing plates 52 and fall onto the spiral arc plate 54 . The spiral arc plate 54 rotates to drive the black soldier fly larvae to move downward evenly, so that the black soldier fly larvae can be evenly inactivated inside the inner shell 322 .
[0052] Specifically, when feeding, the black soldier fly larvae enter the water bath cylinder 32 in a dispersed manner from the channel formed inside the feed grid 23, ensuring that the black soldier fly larvae can be evenly dispersed for inactivation. During the inactivation process, the material leveling plate 52 can effectively prevent the black soldier fly larvae from struggling and splashing upward due to heat, and the spiral arc plate 54 arranged in sections along the vertical direction fixes the struggling interval of the black soldier fly larvae. Through the cooperation of the feed grid 23 and the spiral arc plate 54, the black soldier fly larvae can be evenly dispersed inside the water bath cylinder 32 for uniform inactivation, thereby greatly improving the uniformity of the inactivation of the black soldier fly larvae, and to a certain extent, it can also avoid the uneven distribution of the black soldier fly larvae, which leads to long-term contact with the spiral arc plate 54 and carbonization.
[0053] In summary, through the cooperation of the feed grid 23 and the spiral arc plate 54, the uniformity of the feeding and inactivation of the black soldier fly larvae can be ensured, and the carbonization of the black soldier fly larvae during the inactivation process can be effectively avoided. However, after the inactivation is completed, there is also the situation of uneven drying during the drying process, which leads to the extension of the drying time and the increase of the drying cost. On this basis, the present application is also provided with a conveying component 6 and a solar drying component 7, so that after the inactivation of the black soldier fly larvae is completed, the water in the body can be evenly and quickly removed to complete the drying.
[0054] Please refer to Figure 1-2 A conveying assembly 6 is provided at the bottom of the water bath cylinder 32, and the conveying assembly 6 includes a conveying bracket 61 installed on the top of the mounting base 1, and the other end of the conveying bracket 61 is in contact with the solar drying assembly 7. A set of conveying rollers 63 are rotatably connected at both ends of the conveying bracket 61, and a conveyor belt 64 is provided between the two sets of conveying rollers 63. A conveying motor 62 is connected to the side wall of a set of conveying rollers 63 close to the side of the water bath cylinder 32. The conveying motor 62 can drive the conveying rollers 63 to rotate, and during the rotation of the conveying rollers 63, the conveyor belt 64 can be synchronously driven to move. After the inactivation is completed, the black soldier fly larvae are discharged from the discharge port 34 and arrive at the conveyor belt 64, and the conveyor belt 64 continues to transport the black soldier fly larvae to the solar drying assembly 7 for drying treatment.
[0055] Please refer to Figure 1-2 and Figure 7-11 A solar drying assembly 7 is installed on one side of the inactivation cylinder assembly 3. The solar drying assembly 7 includes a horizontally arranged heat storage bin 72, two groups of drying bins 73 connected to the heat storage bin 72, a heat collecting mechanism 71 installed on the heat storage bin 72, and a turning mechanism 74 arranged inside the drying bin 73. The heat collecting mechanism 71 includes a heat collecting bin 711 installed on the top of the heat storage bin 72, and a heat collecting plate 712 is installed inside the heat collecting bin 711. The heat collecting plate 712 can receive solar energy and convert it into heat energy. A drying fan 721 is arranged on the side wall of the heat storage bin 72 close to the heat collecting mechanism 71, and a heat storage plate 722 is arranged inside the heat storage bin 72. The heat storage plate 722 is arranged as a corrugated structure, and the heat energy generated by the heat collecting plate 712 can be transferred to the heat storage plate 722, thereby increasing the temperature of the heat storage plate 722. The operation of the drying fan 721 can generate a path for the outdoor air. When the air flows through the heat storage plate 722, the air inside the heat storage bin 72 is heated by convection heat exchange. The heat storage bin 72 is connected to the drying bin 73, so that the hot air flows into the drying bin 73 to dry the black soldier fly larvae inside the drying bin 73 and remove moisture from their bodies.
[0056] Please refer to Figure 1-2 and Figure 7-11, a storage cover is slidably connected to the drying bin 73, and the sliding storage cover can open the drying bin 73. A set of material turning mechanism 74 is arranged inside each drying bin 73. After the drying bin 73 is opened, the inactivated black soldier fly larvae enter the material turning mechanism 74 from the end of the conveyor belt 64, and then the drying bin 73 is closed to carry out drying treatment. Each set of material turning mechanism 74 includes a material rack 741 installed inside the drying bin 73, and the material rack 741 is arranged to be a rectangular structure with a shape adapted to the shape inside the drying bin 73. A motor mounting frame is arranged in the middle of the material rack 741, and two sets of material turning motors 742 are symmetrically installed inside the motor mounting frame. The material turning motor 742 is installed at the bottom of the motor mounting frame, and its output end is sleeved with a driving gear 745. Multiple sets of material turning shafts 744 are rotatably connected inside the material rack 741, and the material turning shafts 744 are symmetrically arranged about the motor mounting frame in the middle of the material rack 741. One end of the material turning shaft 744 is rotatably installed on the side wall of the motor mounting frame, and the other end is rotatably installed on the side wall of the material rack 741. The gap between the two groups of turning shafts 744 is smaller than the width of the black soldier fly larvae, and the black soldier fly larvae can be placed on multiple groups of turning shafts 744. The height of the material rack 741 is higher than the height of the turning shafts 744, which can prevent the black soldier fly larvae from falling. The end of each group of turning shafts 744 is connected to a matching gear 743 that meshes with the driving gear 745 on the turning motor 742. The turning motor 742 can drive the driving gear 745 to rotate, and then the turning shaft 744 is driven to rotate through the meshing of the driving gear 745 and the matching gear 743.
[0057] Specifically, the inactivated black soldier fly larvae are transported to the turning mechanism 74 inside the drying bin 73 by the conveying assembly 6, and the black soldier fly larvae are stacked on multiple groups of turning shafts 744. The turning shafts 744 are driven to rotate by the turning motor 742, and the black soldier fly larvae are gradually moved to the gap between the two groups of turning shafts 744. Then, the hot air generated inside the heat storage bin 72 passes through the gap between the two groups of turning shafts 744 to dry the black soldier fly larvae. During the drying process, the turning shafts 744 are continuously rotated, so that the black soldier fly larvae located in the gap between the turning shafts 744 are evenly turned over. Not only can the uniformity of the drying of the black soldier fly larvae be ensured, but also the drying time of the black soldier fly larvae can be reduced, thereby improving the drying efficiency.
