Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spore separation devices after solid-state fermentation of fungi, and more specifically, to a spore elution device. Background Technology
[0002] In agriculture, the use of traditional chemical pesticides has revealed several shortcomings. Firstly, pests and diseases commonly develop resistance to chemical pesticides. The more pesticides needed to combat resistance, the greater the damage to the ecological balance. Secondly, the ban on high-residue pesticides has led to short-lasting effects and recurring pest and disease outbreaks, causing problems for agricultural production. In contrast, biological control methods, particularly the use of microorganisms to control pests and diseases, offer a green and long-lasting solution.
[0003] Fungi have the functions of disease resistance, growth promotion, and pest control. Traditionally, fungal spores are obtained by drying fermented solid materials, separating the spore powder, and then processing it into various dosage forms. The method of separating spores after drying the material is suitable for making powders, but if used to make water suspensions or oil suspensions, the process is more complicated and costly.
[0004] Existing technology discloses a spore separation device, a spore separation method, and a spore collection system. The spore separation device includes a separation tank with a feed inlet and a water outlet at the top; an axial stirring paddle disposed within the separation tank to move the solid fermentation product along the axial direction of the separation tank; and a radial stirring paddle disposed within the separation tank, detachably connected above the axial stirring paddle, to rotate the solid fermentation product circumferentially within the separation tank. In this scheme, spore separation is achieved by adding water to the separation tank and utilizing the axial stirring paddle to generate axial ripples in the water. However, this scheme also requires the radial stirring shaft to generate circumferential rotational thrust in the water to maintain the spore separation state, sequentially discharging the spores and solid fermentation product. This operation is cumbersome, cannot achieve continuous spore separation, and is inefficient. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot continuously separate and produce spores, and to provide a spore elution device that enables continuous spore separation and improves production efficiency.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A spore elution apparatus is provided, comprising a conveying mechanism, an ultrasonic transducer, and an elution tank for holding liquid solvent; the ultrasonic transducer is disposed at the bottom of the elution tank; the conveying mechanism includes a driving component, a drive shaft, a driven shaft, a limiting shaft assembly, and a conveyor belt, the output end of the driving component is connected to the drive shaft, the conveyor belt is wound around the drive shaft and the driven shaft, the limiting shaft assembly is in contact with the conveyor belt, the drive shaft and the driven shaft are rotatably mounted on both sides of the elution tank respectively, and the limiting shaft assembly is used to restrict one side of the conveyor belt within the elution tank and restrict the other side of the conveyor belt below the elution tank; the conveyor belt has a plurality of chambers, and a plurality of first pores are arrayed on the inner side of the conveyor belt, the first pores communicating with the chambers, the first pores being used to allow spores to pass through and to intercept undissolved particles of solid fermentation product; the elution tank has a liquid outlet.
[0008] This invention relates to a spore elution device. In operation, liquid solvent is continuously injected into the elution tank. A drive unit rotates the main shaft, causing the driven shaft and conveyor belt to move continuously. Solid fermentation material is continuously introduced into the chamber from above the conveyor belt. Ultrasonic transducers elute the spores adhering to the surface of the solid fermentation material into the liquid solvent. During the cyclical movement of the conveyor belt, spores can pass through the first pore, while insoluble particles of the solid fermentation material are retained in the chamber. When the solid fermentation material passes the main shaft, the conveyor belt changes direction, and the insoluble particles are dislodged by gravity. The eluted spores are discharged through the outlet. This invention simplifies the spore separation operation through the conveyor belt, enabling continuous spore separation and improving production efficiency. Furthermore, the device can be developed into a large-scale industrial production unit and can be embedded in the production process as a unit structure for fungal spore liquid preparations. The spore liquid prepared by this device can be used directly or further processed into aqueous or oil suspensions, simplifying the process and reducing production costs.
[0009] Furthermore, the conveyor belt includes an inner layer, an outer layer, and two spacer layers. One spacer layer connects one end of the outer layer and one end of the inner layer, and the other spacer layer connects the other end of the outer layer and the other end of the inner layer. The first pore is located in the inner layer, and the outer layer array has an opening communicating with the chamber. Solid fermentation material enters or exits the chamber through the opening, while liquid solvent can pass through the first pore. Under the action of an ultrasonic transducer, spores can be eluted. The eluted spores can be discharged from the chamber through the first pore to the elution tank and finally discharged from the outlet.
[0010] Furthermore, the spacer layer array is provided with a plurality of second pores, which are used to allow spores to pass through and to intercept insoluble particles of the solid fermentation product. When the conveyor belt moves from the liquid solvent to outside the elution tank, the conveyor belt tilts, allowing spores to separate from insoluble particles through the second pores in addition to the first pores.
[0011] Furthermore, both the inner layer and the spacer layer are mesh structures composed of intersecting diagonal bars.
[0012] Furthermore, the outer layer is a grid structure composed of horizontal and vertical bars arranged vertically.
[0013] Furthermore, the limiting shaft assembly includes a first limiting shaft and a second limiting shaft. The first limiting shaft is located inside the elution tank and contacts the outer layer. The second limiting shaft is located below the elution tank and contacts the inner layer. The first limiting shaft, in conjunction with the driven shaft, guides the conveyor belt, causing the conveyor belt carrying the solid fermentation material to turn and enter the elution tank for spore elution. The first limiting shaft, in conjunction with the drive shaft, guides the conveyor belt, allowing the solid material after spore elution to be transported out of the elution tank. The second limiting shaft, in contact with the inner layer, guides the conveyor belt, separating the inner layer of the conveyor belt from the elution tank to prevent interference between the movement of the conveyor belt and the elution tank, ensuring the normal operation of the conveyor belt.
[0014] Furthermore, there are two first limiting shafts and two second limiting shafts. The two first limiting shafts are respectively positioned close to the driving shaft and the driven shaft, and the two second limiting shafts are also respectively positioned close to the driving shaft and the driven shaft. The portion of the conveyor belt located between the two first limiting shafts allows for sufficient spore elution, while the portion of the conveyor belt located between the two second limiting shafts maintains a distance from the elution tank, ensuring effective spore elution and normal operation of the conveyor belt.
[0015] Furthermore, the second limiting shaft is located between the drive shaft and the driven shaft. After leaving the washing tank, the conveyor belt turns via the drive shaft, and the second limiting shaft located between the drive shaft and the driven shaft guides the conveyor belt so that the opening of the conveyor belt tilts downward after turning via the drive shaft, which helps to automatically unload undissolved particles.
[0016] Furthermore, it also includes a spore collection tank located below the liquid outlet.
[0017] Furthermore, it also includes a solid material collection bin, which is located below the drive shaft.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] It enables continuous separation and elution of spores, improving production efficiency. Attached Figure Description

[0026] Example 1
[0027] This embodiment is the first embodiment of the spore elution device, such as... Figures 1 to 3As shown, the system includes a conveying mechanism, an ultrasonic transducer 2, and an elution tank 1 for holding liquid solvent. The ultrasonic transducer 2 is located at the bottom of the elution tank 1. The conveying mechanism includes a drive component, a drive shaft 3, a driven shaft 4, a limiting shaft assembly 5, and a conveyor belt 6. The output end of the drive component is connected to the drive shaft 3. The conveyor belt 6 winds around the drive shaft 3 and the driven shaft 4. The limiting shaft assembly 5 contacts the conveyor belt 6. The drive shaft 3 and the driven shaft 4 are rotatably mounted on both sides of the elution tank 1. The limiting shaft assembly 5 is used to confine one side of the conveyor belt 6 within the elution tank 1 and to confine the other side of the conveyor belt 6 below the elution tank 1. The conveyor belt 6 has several chambers, and the inner side of the conveyor belt 6 is arrayed with multiple first pores 611. The first pores 611 communicate with the chambers and are used to allow spores to pass through and to intercept undissolved particles of solid fermentation material. The elution tank 1 has a liquid outlet 11.
[0028] In the aforementioned spore elution device, liquid solvent is continuously injected into the elution tank 1. A drive unit rotates the drive shaft 3, causing the driven shaft 4 and conveyor belt 6 to move continuously. Solid fermentation material is continuously introduced into the chamber from above the conveyor belt 6. The ultrasonic transducer 2 elutes the spores adhering to the surface of the solid fermentation material into the liquid solvent. During the cyclical movement of the conveyor belt 6, spores can pass through the first pore 611, while insoluble particles of the solid fermentation material are retained in the chamber. When the solid fermentation material passes the drive shaft 3, the conveyor belt 6 changes direction, and the insoluble particles are unloaded by gravity. The eluted spores are discharged through the outlet 11. In this embodiment, the conveyor belt 6 simplifies the spore separation operation, enabling continuous spore separation and improving production efficiency. Furthermore, the device can be developed into a large-scale industrial production equipment, serving as a unit structure embedded in the production process for fungal spore liquid preparations. The spore liquid prepared by this device can be used directly or further processed into an aqueous or oil suspension, simplifying the process and reducing production costs.
[0029] like Figure 2 , Figure 3 As shown, the conveyor belt 6 includes an inner layer 61, an outer layer 62, and two spacer layers 63. One spacer layer 63 connects one end of the outer layer 62 and one end of the inner layer 61, and the other spacer layer 63 connects the other end of the outer layer 62 and the other end of the inner layer 61. A first pore 611 is provided in the inner layer 61, and the outer layer 62 is arrayed with openings 621 communicating with the chamber. In practice, solid fermentation material enters or exits the chamber through the openings 621, and liquid solvent can pass through the first pore 611. Under the action of the ultrasonic transducer 2, spores can be eluted. The eluted spores can be discharged from the chamber to the elution tank 1 through the first pore 611, and finally discharged from the outlet 11.
[0030] like Figure 3As shown, the spacer layer 63 array is provided with multiple second pores 631, which are used to allow spores to pass through and to intercept insoluble particles of the solid fermentation product. The ultrasonic transducer 2 washes the spores adhering to the surface of the solid fermentation product into the liquid solvent. During the cyclic movement of the conveyor belt 6, when the conveyor belt 6 moves from the liquid solvent to outside the elution tank 1, the conveyor belt 6 tilts, and in addition to the first pore 611, the spores can also be separated from the insoluble particles through the second pores 631.
[0031] like Figure 2 , Figure 3 As shown, the inner layer 61 and the spacer layer 63 are both mesh structures composed of intersecting diagonal bars, while the outer layer 62 is a grid structure composed of vertically arranged horizontal and vertical bars. The intersecting diagonal bars form first pores 611 and second pores 631, and the vertically arranged horizontal and vertical bars form openings 621. The size of the first pore 611 is smaller than that of the opening 621. The first pore 611 allows spores to pass through while intercepting undissolved particles of the solid fermentation product, and the opening 621 allows for convenient continuous introduction and discharge of solid materials.
[0032] Specifically, the first pore 611 and the second pore 631 can be set between 10 mesh and 500 mesh according to different material diameters. The liquid solvent includes, but is not limited to, water, vegetable oil, mineral oil, polyether, Span, Tween, glycolipids, and other solvents.
[0033] Example 2
[0034] This embodiment is a second embodiment of the spore elution device. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 1 , Figure 2 As shown, the limiting shaft assembly 5 includes a first limiting shaft 51 and a second limiting shaft 52. The first limiting shaft 51 is located inside the elution tank 1 and contacts the outer layer 62. The second limiting shaft 52 is located below the elution tank 1 and contacts the inner layer 61. In practice, the first limiting shaft 51, in conjunction with the driven shaft 4, guides the conveyor belt 6, causing the conveyor belt 6 containing solid fermentation material to turn and enter the elution tank 1 for spore elution. The first limiting shaft 51, in conjunction with the drive shaft 3, guides the conveyor belt 6, allowing the solid material after spore elution to be transported out of the elution tank 1. The second limiting shaft 52, in contact with the inner layer 61, guides the conveyor belt 6, separating the inner layer 61 of the conveyor belt 6 from the elution tank 1, preventing interference between the movement of the conveyor belt 6 and the elution tank 1, and ensuring the normal operation of the conveyor belt 6.
[0035] like Figure 1 , Figure 2As shown, there are two first limiting shafts 51 and two second limiting shafts 52. The two first limiting shafts 51 are respectively positioned close to the drive shaft 3 and the driven shaft 4, and the two second limiting shafts 52 are respectively positioned close to the drive shaft 3 and the driven shaft 4. Specifically, the bottom of the elution tank 1 is horizontal, the two first limiting shafts 51 are at the same horizontal height, and the two second limiting shafts 52 are at the same horizontal height. The portion of the conveyor belt 6 located between the two first limiting shafts 51 can perform sufficient spore elution, while the portion of the conveyor belt 6 located between the two second limiting shafts 52 can maintain a distance from the elution tank 1 to ensure the spore elution effect and the normal operation of the conveyor belt 6. Specifically, relative to the conveyor belt 6 between the two first limiting shafts 51, the height of the inner layer 61 is lower than the height of the liquid outlet 11, and the height of the outer layer 62 is higher than the height of the liquid outlet 11, ensuring that the liquid solvent can immerse the material in the conveyor belt 6 without causing the material to leak out from the opening 621.
[0036] like Figure 1 , Figure 2 As shown, the second limiting shaft 52 is located between the drive shaft 3 and the driven shaft 4. In practice, after the conveyor belt 6 leaves the washing tank 1, it turns via the drive shaft 3. The second limiting shaft 52 located between the drive shaft 3 and the driven shaft 4 guides the conveyor belt 6, so that after the conveyor belt 6 turns via the drive shaft 3, the opening 621 tilts downward, which helps the undissolved particles to be automatically unloaded.
[0037] Example 3
[0038] This embodiment is the third embodiment of the spore elution device. This embodiment is similar to Embodiment Two, except that it also includes a solid material collection chamber, which is located below the drive shaft 3. During implementation, after the conveyor belt 6 turns past the drive shaft 3, the opening 621 tilts downwards, and the undissolved particles fall into the solid material collection chamber under gravity.
[0039] It also includes a spore collection tank, which is located below the liquid outlet 11. When the ultrasonic transducer 2 washes the spores adhering to the surface of the solid fermentation material into the liquid solvent, the spores can be discharged into the spore collection tank through the first pore 611 and the second pore 631 along with the liquid solvent through the liquid outlet 11.
[0040] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
