Technical Field
[0001] This utility model relates to the field of insect drying technology, specifically to an insect drying device. Background Technology
[0002] Insects used as protein feed need to be dried to reduce their moisture content in order to extend their shelf life.
[0003] Currently, insect drying devices employ methods such as microwave drying, infrared drying, and hot air drying. Announcement No. CN219103611U discloses a tower-type drying device, comprising a feeding assembly, a drying tower body, and a discharging assembly installed sequentially from top to bottom. The drying tower body includes a drying chamber and air inlet and outlet boxes installed on both sides of the drying chamber. An air inlet pipe is provided at the bottom of the air inlet box, and the top of the air outlet box is connected to an air outlet. Baffles for deflecting hot air are alternately installed inside the air inlet and outlet boxes. Heat equalization plates are alternately and obliquely installed on the inner walls of the two side plates of the drying chamber. Air holes are provided on the box body below each heat equalization plate, and a discharge port is provided at the bottom of the drying chamber.
[0004] In the aforementioned drying device, inclined baffles are used to extend the falling time of materials in the drying chamber, which can prolong the contact time between hot air and materials. However, the baffle angle is fixed, and it is impossible to optimize the hot air distribution and material residence time by adjusting the baffle angle. Utility Model Content
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an insect drying device that solves the technical problem that the angle of the baffle plate in the existing drying device cannot be adjusted.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] This utility model provides an insect drying device, comprising:
[0008] The shell structure includes a drying container, a baffle and a limiting member. The drying container has a falling channel for material to fall. The baffle is inclinedly built into the falling channel and is rotatably connected to the drying container on one side. The limiting member is connected to both the baffle and the drying container and is used to adjust the inclination angle of the baffle.
[0009] A heating mechanism, which is connected to the housing mechanism, is used to dry the material in the falling channel.
[0010] In one embodiment, the limiting member includes a limiting portion, one end of which is located outside the drying container and the other end of which extends into the falling flow channel and abuts against and supports the other side of the baffle portion. The limiting portion is connected to the drying container and is movable relative to the drying container.
[0011] In one embodiment, the limiting portion is threadedly connected to the drying container.
[0012] In one embodiment, the limiting member further includes an elastic portion connected to the baffle portion and the drying container, for providing elastic force for the baffle portion to conform to the limiting portion.
[0013] In one embodiment, the insect drying device further includes a heating mechanism connected to the housing mechanism for drying the material in the falling channel.
[0014] In one embodiment, the drying container is provided with an exhaust port connected to the falling flow channel.
[0015] In one embodiment, the insect drying device further includes an airflow mechanism connected to the falling channel, which is used to generate airflow within the falling channel, and the direction of airflow is opposite to the direction of material falling in the falling channel.
[0016] In one embodiment, the drying container is provided with an exhaust port connected to the falling flow channel.
[0017] In one embodiment, the drying container further includes a filter screen disposed at the exhaust port.
[0018] In one embodiment, the airflow mechanism includes a blower, the outlet of which is connected to the falling flow channel.
[0019] In one embodiment, the drying container is provided with a plurality of air inlets;
[0020] The housing mechanism further includes a sleeve, which is fitted onto the drying container and forms an annular cavity with the drying container. The annular cavity is connected to a plurality of air inlets.
[0021] The air outlet of the blower is connected to the annular cavity.
[0022] In one embodiment, the airflow mechanism includes a fan, the air inlet of which is connected to the exhaust port.
[0023] Compared with existing technologies, the insect drying device provided by this utility model activates the heating mechanism when drying mealworms, and introduces the mealworms into the falling channel. The falling mealworms come into contact with the baffle and change their falling direction under the guidance of the baffle, which can prolong the residence time of the mealworms in the drying container. The heating mechanism can heat the falling mealworms, so that the mealworms are dried during the falling process. For mealworms of different numbers and different growth stages, the falling speed of the mealworms can be adjusted by adjusting the tilt angle of the baffle, thereby adjusting the residence time of the mealworms in the drying container so that the mealworms are properly dried. When it is necessary to adjust the tilt angle of the baffle, the baffle is controlled to rotate relative to the drying container by the limiting component to adjust the tilt angle of the baffle, thus realizing the adjustment of the tilt angle of the baffle. At the same time, the mealworms fall downwards by the baffle, which can prevent the mealworms from piling up during the drying process and prevent the moisture from being unable to flow out.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0033] To address the technical problem that the angle of the baffle plate in a drying device cannot be adjusted, this invention provides an insect drying device in which the angle of the baffle plate can be adjusted as needed.
[0034] It should be noted that the insect drying device described in this utility model is used for, but not limited to, drying mealworms. For ease of explanation, this utility model only uses the application of the insect drying device to drying mealworms as an example. The principle of the insect drying device applied to drying other types of insects is essentially the same as that applied to drying mealworms, and will not be described in detail here.
[0035] Please see Figure 2 , Figure 2 This is a partial structural diagram of the limiting member in an insect drying device according to an embodiment of the present invention. The insect drying device includes a shell mechanism 1 and a heating mechanism 2. The shell mechanism 1 includes a drying container 11, a baffle 12 and a limiting member 13. The drying container 11 has a falling channel 11a for material to fall. The baffle 12 is inclinedly built into the falling channel 11a and is rotatably connected to the drying container 11 on one side. The limiting member 13 is connected to both the baffle 12 and the drying container 11 and is used to adjust the tilt angle of the baffle 12. The heating mechanism 2 is connected to the shell mechanism 1 and is used to dry the material in the falling channel 11a.
[0036] When drying mealworms, the heating mechanism 2 is activated, and the mealworms are introduced into the falling channel 11a. The falling mealworms come into contact with the baffle section 12 and change their falling direction under the guidance of the baffle section 12, which can prolong the residence time of the mealworms in the drying container 11. The heating mechanism 2 can heat the falling mealworms, so that the mealworms are dried during the falling process. For mealworms of different numbers and different growth stages, the falling speed of the mealworms can be adjusted by adjusting the tilt angle of the baffle section 12, so as to adjust the residence time of the mealworms in the drying container 11 and make the mealworms properly dried. When it is necessary to adjust the tilt angle of the baffle section 12, the limit member 13 controls the rotation of the baffle section 12 relative to the drying container 11 to adjust the tilt angle of the baffle section 12, thus realizing the adjustment of the tilt angle of the baffle section 12. At the same time, the mealworms fall downwards by the baffle, which can prevent the mealworms from piling up during the drying process and prevent the moisture from being unable to flow outwards.
[0037] It should be understood that the drying container 11 can be a cylinder, a box, or a tube, etc., specifically, such as Figure 1As shown, in one embodiment, the drying container 11 is a cylindrical body, and the shell mechanism 1 further includes a guide plate 16 disposed at the bottom of the drying container 11. The guide plate 16 is inclined and an outlet 11c for the mealworms to slide out is formed between the guide plate 16 and the side wall of the drying container 11. An inlet is formed at the top of the drying container 11.
[0038] It should be understood that the flow baffle 12 can be a baffle plate, a baffle vane, etc., and the number of flow baffles 12 can be one, two, or more, for example, Figure 1 As shown, in one embodiment, the flow deflector 12 is a baffle plate, and there are multiple flow deflectors 12. The multiple flow deflectors 12 are distributed alternately and at intervals along the material falling direction in the falling channel 11a.
[0039] It should be understood that the heating mechanism 2 can be a microwave drying device, an infrared drying device, or a hot air drying device. When the heating mechanism 2 is a microwave drying device, a sliding gate (not shown in the figure) is provided at the bottom of the drying container 11. The discharge port 11c is opened or closed by the sliding gate. When the heating mechanism 2 is a microwave drying device, the microwaves emitted by the microwave drying device enter the drying container 11 and can dry the mealworms in the drying container 11. However, microwaves have penetrating power. In order to prevent the microwaves from passing through the discharge port, a gate that can be opened and closed is provided in this embodiment. When microwave drying is performed, the gate is closed. After drying is completed, microwave drying is stopped, the gate is opened, and the dried mealworms slide out of the drying container 11.
[0040] It should be understood that, in order to adjust the setting angle of the baffle 12, a sliding groove can be provided in the drying container 11 along the rotation direction of the baffle 12. The limiting member 13 can be a limiting bolt (not shown in the figure). The threaded end of the limiting screw passes through the sliding groove and is connected to the baffle 12. By sliding the limiting screw, the setting angle of the baffle 12 can be adjusted. By tightening the limiting screw, the baffle 12 after rotation can be fixed.
[0041] It should be understood that the limiting member 13 can also be other structures, specifically, such as Figure 2 As shown, in one embodiment, the limiting member 13 includes a limiting part 131, one end of which is located outside the drying container 11, and the other end of which extends into the falling flow channel 11a and abuts against and supports the other side of the baffle part 12. The limiting part 131 is connected to the drying container 11 and can move relative to the drying container 11.
[0042] When it is necessary to adjust the setting angle of the baffle section 12, the length of the limiting part 131 extending into the falling flow channel 11a is adjusted to push the limiting part 131 to rotate relative to the drying container 11, thereby realizing the adjustment of the setting angle of the baffle section 12.
[0043] It should be understood that the limiting part 131 and the drying container 11 can be slidably connected, and the limiting part 131 can also be a telescopic rod with built-in telescopic damping, specifically, as shown in the example. Figure 2 As shown, in one embodiment, the limiting part 131 is threadedly connected to the drying container 11.
[0044] By threading the limiting part 131 to the drying container 11, the distance by which the limiting part 131 extends into the falling flow channel 11a can be adjusted by rotating the limiting part 131. Moreover, the self-locking of the thread allows the rotating limiting part 131 to be fixed relative to the drying container 11.
[0045] To prevent the baffle 12 from rotating upwards under the influence of airflow, therefore, as follows: Figure 2 As shown, in one embodiment, the limiting member 13 further includes an elastic portion 132, which is connected to the baffle portion 12 and the drying container 11, and is used to provide elasticity for the baffle portion 12 to fit against the limiting portion 131.
[0046] In this embodiment, by providing the elastic part 132, the elastic part 132 can push the baffle part 12 to fit against the limiting part 131, thereby preventing the baffle part 12 from rotating upward under the push of the airflow.
[0047] It should be understood that the elastic part 132 can be a spring, torsion spring, or spring sheet, etc.
[0048] In order to remove the moisture formed during the drying process of mealworms, in one embodiment, the insect drying device further includes an airflow mechanism 3, which is connected to the falling channel 11a to form an airflow in the falling channel 11a, and the direction of the airflow is opposite to the direction of the falling material in the falling channel 11a.
[0049] By setting up the airflow mechanism 3, the airflow mechanism 3 can generate airflow in the falling channel 11a. The airflow can carry the moisture generated during the drying process of the mealworms, which facilitates the rapid drying of the mealworms.
[0050] In order to remove the moisture formed during the drying process, for this reason, such as Figure 4 As shown, in one embodiment, the drying container 11 is provided with an exhaust port that is connected to the falling channel 11a.
[0051] The airflow formed in the falling channel 11a can be discharged from the exhaust port.
[0052] It should be understood that the exhaust port can be located at the top of the drying container 11 or on the side wall of the drying container 11.
[0053] To prevent the airflow from carrying mealworms out of the exhaust port, therefore, such as Figure 4 As shown, in one embodiment, the drying container 11 further includes a filter screen 14 disposed at the exhaust port.
[0054] By setting up the filter screen 14, the exhaust gas can be filtered and mealworms can be intercepted in the falling channel 11a.
[0055] In order to create an airflow in the falling channel 11a that is opposite to the direction of material falling, for this purpose, such as Figure 1 As shown, in one embodiment, the airflow mechanism 3 includes a blower 31, the outlet of which is connected to the falling flow channel 11a.
[0056] By providing a blower 31, the blower 31 can inject air into the falling channel 11a to form an airflow in the falling channel 11a that is opposite to the direction of material falling.
[0057] In order to ensure that air is evenly blown into the drying container 11, therefore, as follows: Figure 3 As shown, in one embodiment, the drying container 11 is provided with a plurality of air inlets 11b; the housing mechanism 1 also includes a sleeve 15, which is fitted onto the drying container 11 and forms an annular cavity with the drying container 11, and the annular cavity is connected to the plurality of air inlets 11b; the air outlet of the blower 31 is connected to the annular cavity.
[0058] In this embodiment, the blower 31 blows air into the annular cavity, and the pressurized air enters the air inlet 11b from the annular cavity and then enters the falling flow channel 11a through the air inlet 11b.
[0059] It should be understood that, in order to create an airflow opposite to the direction of material fall, for this purpose, such as Figure 3 As shown, in one embodiment, an air inlet 11b is provided on the peripheral wall of the bottom of the drying container 11.
[0060] In order to create an airflow in the falling channel 11a that is opposite to the direction of material falling, such as Figure 1 As shown, in one embodiment, the airflow mechanism 3 includes a blower 32, the air inlet of which is connected to the exhaust port.
[0061] By setting up an exhaust fan 32, the exhaust fan 32 draws the airflow in the drying container 11 outward through the exhaust port. During the process of drawing out the air, an airflow is formed in the drying container 11, and the flow direction of the airflow is opposite to the falling direction of the material.
[0062] It should be understood that an exhaust fan 32 can be set separately to form an airflow opposite to the direction of material falling, or a blower 31 can be set separately to form an airflow opposite to the direction of material falling, or both a blower 31 and an exhaust fan 32 can be set simultaneously to form an airflow opposite to the direction of material falling within the falling channel 11a. Setting both a blower 31 and an exhaust fan 32 simultaneously makes the air pressure of the airflow flowing in opposite directions within the falling channel 11a more uniform, avoiding a large difference in air pressure between the top and bottom of the drying container 11.
[0063] It should be understood that the force of the blower 31 and the exhaust fan 32 can be adjusted so that the mealworms in the falling channel 11a can fall relative to the airflow under the action of gravity, avoiding excessive air pressure or flow velocity that would prevent the mealworms from falling.
[0064] To facilitate the falling of mealworms, a vibrator (not shown in the figure) can be installed on the outer wall of the drying container 11.
[0065] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
