Description

Technical Field

[0001] The invention relates to the field of biotechnology, in particular to a microcapsule eel bait and a preparation method thereof. Background Art

[0002] Microcapsule eel starter bait is a special aquatic fry bait produced by microcapsule encapsulation technology. It is specially designed to meet the nutritional needs and feeding habits of eel fry (especially young fish in the start feeding stage). Its core feature is to encapsulate highly nutritious active ingredients in degradable microcapsules to achieve slow release, anti-loss, and anti-water quality interference effects. Corresponding manufacturing equipment is required in the process of bait production. For this purpose, a Chinese patent discloses a dehydration centrifuge for bait production, and the application number is 202111427309.5. A preparation device and preparation method of aquaculture seedling starter bait, through the setting of a vibration device, the material can be efficiently dropped into the feeding chamber during the batching, avoiding the problem that the discharge port is blocked when there is a lot of material; and the material remains in the batching chamber when there is little material, thereby effectively improving the batching efficiency;

[0003] However, the current microcapsule eel bait preparation equipment lacks a corresponding connecting molding structure during use, which makes it impossible to connect the bait during the production process of the bait preparation equipment. As a result, the raw materials need to be transported through multiple layers during the production process, thereby reducing the overall production convenience and smoothness of the preparation equipment. Summary of the Invention

[0004] The present invention provides a microcapsule eel bait and a preparation method thereof, which can effectively solve the problem that the microcapsule eel bait preparation equipment proposed in the above background technology lacks a corresponding connecting molding structure during use, resulting in the inability to connect the bait during the production process of the bait preparation equipment, so that the raw materials need to be transported in multiple layers during the production process of the bait, thereby reducing the overall production convenience and use fluency of the preparation equipment.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for preparing microcapsule eel bait, comprising the following steps:

[0006] S1. The lifting isolation circular plate is driven upward by the transfer deformation telescopic tube, and fits with the bottom surface of the feeding isolation sleeve to form a temporarily sealed mixing chamber. During the process, the sealing telescopic rubber ring expands and inhales air, causing the expansion conical rubber sleeve to tighten and cover the central mixing paddle, completing the seal and starting mixing;

[0007] S2. After mixing is completed, the telescopic tube contracts, the isolation disc moves downward, and the gas flows back to the expansion cone rubber sleeve. The expansion cone rubber sleeve expands upward, and the mixed raw materials fall into the upper guide cone and then fall into the hard filter drum. The mixed raw materials are received by the flexible deformable filter mesh that is deformed into an inverted cone to achieve centrifugal dehydration.

[0008] S3, after dehydration, the raw materials fall into the extrusion arc sleeve, are stirred by the internal separation extrusion arc plate and extruded through the conical extrusion side tube, and the external separation scraper separates the particles, and the preliminary formed bait particles fall downwards;

[0009] S4: The bait particles fall onto the spiral rotating plate and are trimmed into a more rounded shape during the low-speed rotation. The discharge arc guide plate uses centrifugal force to send the particles into the reflux separation side cylinder to complete the bait forming process.

[0010] S5. The raw materials attached to the inside of the equipment are recovered by rotating the circulation motor and flushing the inner ring with water. The bottom circulation fan is then used to create an upward airflow to assist the return of the bait.

[0036] According to the above technical solution, the bait prepared according to a method for preparing microcapsule eel opening bait is used in the opening and early cultivation stages of eel fry.

[0037] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0038] 1. A three-dimensional forming and dehydrating mechanism is provided. The cooperation between the various components inside the three-dimensional forming and dehydrating mechanism optimizes the bait processing and forming process. Through the structural design of multi-layer processing inside the central forming barrel, during the bait processing process, the raw materials only need to be added from the top of the central forming barrel, and the raw materials can complete the process of mixing, dehydration, forming and trimming from top to bottom. This effectively shortens the bait processing process, avoids the need to transfer the bait raw materials multiple times during the bait production process, and reduces the bait production and forming efficiency. It also effectively improves the overall smoothness of the central forming barrel, ensuring that the upper, middle and lower layers of the preparation equipment can process three batches of bait at the same time, making full use of the space inside the central forming barrel and reducing the production cost of the bait.

[0039] At the same time, through the external combined structural design of the lifting isolation circular plate, the flexible deformable filter and the extruded arc sleeve, the interior of the central formed barrel is divided into multiple relatively independent cavities, and the flexible deformation characteristics of the expansion cone rubber sleeve and the flexible deformable filter are utilized. The shape of the expansion cone rubber sleeve is adjusted by the transfer of the airflow inside the expansion cone rubber sleeve to ensure that the top structure of the lifting isolation circular plate can maintain the corresponding shape during the mixing and discharging of the raw materials. The shape transformation of the flexible deformable filter and the position transformation of the extruded ball can adjust the force direction of the raw materials during the dehydration process, ensuring that the raw materials can continue to remain in the inner circle area of ​​the flexible deformable filter during the dehydration process, thereby effectively improving the overall stability of the internal processing flow of the preparation equipment;

[0040] In addition, through the mutual cooperation between the gears between the bottom-mounted circular plate and the discharge arc guide plate, the rotational speed of the spiral full-circle rotating plate and the discharge arc guide plate can be adjusted, ensuring that the rotating components inside the central forming barrel can rotate smoothly at differential speeds, thereby ensuring that the components involved in the raw material mixing, dehydration and extrusion processes can maintain high-speed rotation to ensure the processing efficiency of the bait. The low-speed rotation of the spiral full-circle rotating plate and the discharge arc guide plate can keep the shape of the bait after molding intact, thereby effectively improving the overall production efficiency and product quality in the bait production process.

[0041] 2. An outer separation circulation mechanism is set up. Through the mutual cooperation between the various components inside the outer separation circulation mechanism, the circulation process of raw materials in the bait production process is optimized. Through the mutual cooperation between the various components inside the reflux separation side cylinder, the formed bait can be quickly air-dried and screened when passing through the reflux separation side cylinder, so as to prevent the bait particles from being mixed with powder and affecting the subsequent processing process, and further improve the product quality of the finished bait. The powder after screening is recycled by airflow, further improving the overall smoothness of the preparation equipment and the utilization rate of raw materials, and effectively improving the smoothness of the discharge of bait particles inside the reflux separation side cylinder;

[0042] At the same time, by optimizing the circulation process of the circulating water inside the center-forming barrel, the utilization rate of the circulating water inside the center-forming barrel is effectively improved, and the internal components of the center-forming barrel are flushed during the water circulation process, so that the raw materials will not adhere to the internal components of the center-forming barrel at will during the transfer process, further improving the smoothness of the operation of the internal components of the center-forming barrel.

[0043] 3. The traditional formula of adding exogenous fillers and adhesives has been improved. By utilizing the characteristics and proportions of the raw materials themselves, a binder-free formula has been developed. The bait can retain its shape in water for at least 5 hours, and the recovery rate is more than 90% within 2 hours, which can ensure the stability of the bait in water and reduce the loss of effective substances.

[0044] To sum up, through the mutual cooperation between the three-dimensional forming and dehydration mechanism and the external separation and circulation mechanism, the bait mixing, dehydration, forming, trimming and screening processes are optimized, and through the mutual cooperation between the deformable components inside the preparation equipment, the smooth progress of the entire production process is ensured. At the same time, the process flow of bait production is effectively shortened, the volume of the entire processing equipment is reduced, the overall volume of the preparation equipment is reduced, and the space cost of the preparation equipment is reduced, thereby effectively improving the overall economic benefits of the bait preparation equipment.

[0066] Example: Figure 1 As shown, the present invention provides a technical solution, a method for preparing microcapsule eel bait, comprising the following steps:

[0067] S1. The lifting isolation circular plate 206 is driven upward by the transfer deformation telescopic tube 205 to fit the bottom surface of the feeding isolation sleeve 210 to form a temporarily sealed mixing chamber. During this process, the sealing telescopic rubber ring 207 expands and absorbs air, causing the expansion conical rubber sleeve 209 to tighten and cover the central mixing paddle 208, completing the seal and starting mixing;

[0068] S2. After mixing is completed, the telescopic tube 205 contracts, the isolation circular plate 206 moves downward, and the gas flows back to the expansion cone rubber sleeve 209. The expansion cone rubber sleeve 209 expands upward, and the mixed raw materials fall into the upper material guide cone 211 and then fall into the hard filter drum 212.

[0070] S4: The bait particles fall onto the spiral full-circle rotating plate 224, where they are trimmed into a more rounded shape during the low-speed rotation. The discharge arc guide plate 225 uses centrifugal force to send the particles into the reflux separation side cylinder 4, completing the bait forming process.

[0071] S5. The raw materials attached to the inside of the equipment are recovered by rotating the circulation motor 508 and flushing the inner ring 504 with water, and then the bottom circulation fan 513 is used to create an upward airflow to assist the bait to return. At the same time, the separated fine powder is recovered and guided back through the bottom structure of the discharge hole circular plate 516.

Through the structural design of the multi-layer processing inside the central forming barrel 1, during the bait processing process, it is only necessary to add the raw materials from the top of the central forming barrel 1, so that the raw materials can complete the mixing, dehydration, forming and trimming processes from top to bottom, effectively shortening the bait processing process flow, avoiding the need to transfer the bait raw materials multiple times during the bait production process, thereby reducing the bait production and forming efficiency, and effectively improving the overall smoothness of the central forming barrel 1, ensuring that the upper, middle and lower layers of the preparation equipment can process three batches of bait at the same time, making full use of the space inside the central forming barrel 1, and reducing the production cost of the bait;

[0083] At the same time, the interior of the central formed barrel 1 is divided into a plurality of relatively independent cavities by the external combined structural design of the lifting isolation circular plate 206, the flexible deformable filter screen 213 and the extruded arc sleeve 219, and the flexible deformation characteristics of the expansion cone rubber sleeve 209 and the flexible deformable filter screen 213 are utilized.

The shape transformation of the flexible deformable filter screen 213 and the position transformation of the extruded ball 216 can adjust the force direction of the raw materials during the dehydration process, ensuring that the raw materials can continue to remain in the inner circle area of ​​the flexible deformable filter screen 213 during the dehydration process, thereby effectively improving the overall stability of the internal processing flow of the preparation equipment.

[0089] A rotating circulation motor 508 is fixedly installed through a net at the middle of the top inner side of the reflux separation side cylinder 4. The rotating circulation motor 508 is powered by an external power supply. A connecting center thin shaft 509 is fixedly connected to the middle of the bottom end of the rotating circulation motor 508. An isolating fine-pore top net 510 is embedded and installed at the top position of the inner side of the reflux separation side cylinder 4.

They are flush with each other, and the top surface of the discharge hole circular plate 515 is tilted toward the discharge arc tube 516 as a whole. The mutual cooperation between the various components inside the outer separation circulation mechanism 5 optimizes the circulation process of raw materials in the bait production process. The mutual cooperation between the various components inside the reflux separation side tube 4 allows the formed bait to be quickly air-dried and screened when passing through the reflux separation side tube 4, so as to prevent the bait particles from being mixed with powder and affecting the subsequent processing process, and further improve the product quality of the finished bait. The powder under screening is recycled by airflow, further improving the overall smoothness of the preparation equipment and the utilization rate of raw materials, and effectively improving the smoothness of the discharge of bait particles inside the reflux separation side tube 4.

[0091] At the same time, by optimizing the circulation process of the circulating water inside the central forming barrel 1, the utilization rate of the circulating water inside the central forming barrel 1 is effectively improved, and the internal components of the central forming barrel 1 are flushed during the water circulation process, so that the raw materials will not adhere to the internal components of the central forming barrel 1 at will during the transfer process, further improving the smoothness of the operation of the internal components of the central forming barrel 1.

[0092] Working principle and use process of the present invention: In actual application, when bait production equipment is needed to process bait, the transfer deformation telescopic tube 205 is extended to drive the lifting isolation circular plate 206 and the bottom surface of the feeding isolation sleeve 210 to slide and fit each other, so that a temporarily sealed mixing and stirring chamber can be formed between the lifting isolation circular plate 206 and the feeding isolation sleeve 210;

[0093] And in the process of rising of the lifting isolation circular plate 206, the inner cavity of the sealing telescopic rubber ring 207 will be driven to expand and increase. Then, in the process of expansion of the sealing telescopic rubber ring 207, the gas inside the expansion conical rubber sleeve 209 will be sucked into the interior of the sealing telescopic rubber ring 207 through the channel inside the central stirring and mixing paddle 208, so that the expansion conical rubber sleeve 209 is tightly wrapped to the outside of the central stirring and mixing paddle 208 under the action of negative pressure. Then, the bait raw materials are added to the interior of the cavity formed by the lifting isolation circular plate 206 and the feeding isolation sleeve 210, and the top drive rotating frame 204 and the components on its top are driven to rotate synchronously through the cooperation between the bottom central drive motor 202 and the central drive shaft 203, and the raw materials inside the feeding isolation sleeve 210 are stirred and mixed by the central stirring and mixing paddle 208;

[0094] When the mixing of the raw materials inside the feeding isolation sleeve 210 is completed and subsequent processing is required, the gas inside the sealing expansion ring 207 is introduced into the expansion conical rubber sleeve 209 by contracting the transfer deformation expansion tube 205, so that the expansion conical rubber sleeve 209 can expand upward into a cone shape and separate from the bottom surface of the feeding isolation sleeve 210 during the downward movement of the lifting isolation circular plate 206, so that the mixed raw materials can fall downward along the edge of the lifting isolation circular plate 206 into the upper material guide cone 211;

[0095] When the mixed raw materials slide along the interior of the upper guide cone 211 into the interior of the hard filter drum 212 and begin to be centrifugally dehydrated, the hard filter drum 212 and the flexible deformable filter screen 213 are driven to rotate at high speed by the central driving shaft 203, and at the same time, the rectangular rotating frame 215 and the squeezing ball 216 are driven to squeeze the flexible deformable filter screen 213 by the extension and contraction of the squeezing adjustment telescopic rod 214, and then the shape of the flexible deformable filter screen 213 is adjusted by the squeezing ball 216, so that the inner diameter of the middle part of the flexible deformable filter screen 213 becomes smaller to form an inverted cone tray shape, so that the friction between the dehydrated raw materials and the inner wall of the flexible deformable filter screen 213 is greater than The gravity exerted on the raw materials ensures that the bait raw materials inside the flexible deformable filter screen 213 will not slide freely during the dehydration process. After the dehydration of the raw materials inside the hard filter drum 212 is completed, the squeezing ball 216 and the flexible deformable filter screen 213 are separated from each other by the contraction of the squeezing adjustment telescopic rod 214, so that the minimum inner diameter of the flexible deformable filter screen 213 is kept the same as the inner diameter of the hard filter drum 212, so that the friction between the dehydrated raw materials and the inner wall of the flexible deformable filter screen 213 is less than the gravity exerted on the raw materials, thereby allowing the bait to gradually slide and fall into the lower conical drum 218 under the action of gravity, thereby completing the dehydration of the bait raw materials.

[0096] When the bait raw material needs to be extruded and shaped, the raw material to be extruded is temporarily stored in the extrusion chamber composed of the extrusion arc sleeve 219 and the internal separation extrusion arc plate 221, and then the internal separation extrusion arc plate 221 and the external separation scraper 222 are driven to rotate by the central driving shaft 203, and the raw material inside the extrusion arc sleeve 219 is extruded through the conical extrusion side tube 220 by the internal separation extrusion arc plate 221, and the raw material particles extruded from the end of the conical extrusion side tube 220 are scraped and separated by the external separation scraper 222, so as to form original bait particles on the outside of the extrusion arc sleeve 219 and fall downward;

[0097] The bait particles falling from the side of the extruded arc sleeve 219 will fall downward to the top of the spiral full-circle rotating plate 224, and at the same time, the center driving gear 223 is driven to rotate by the center driving shaft 203, and the driving side gear ring 226 is driven to rotate through the transmission connecting gear 227 during the rotation of the center driving gear 223, and the spiral full-circle rotating plate 224 and the discharge arc guide plate 225 are driven to rotate synchronously at a low speed during the rotation of the driving side gear ring 226. The bait particles falling to the top of the spiral full-circle rotating plate 224 will trim the shape of the bait particles in the process of rolling downward to make the shape of the bait more rounded, and after the trimmed bait rolls to the top of the discharge arc guide plate 225, the centrifugal force generated during the rotation of the discharge arc guide plate 225 will guide the formed bait through the discharge rectangular side port 3 into the reflux separation side tube 4 to complete the bait molding process;

[0098] When the bait processing needs to be assisted in forming, the circulating water gathered on the top of the waterproof sealing isolation ring 217 during the centrifugal dehydration process can be collected through the diversion rectangular side box 501, and the circulating water inside the diversion rectangular side box 501 is introduced into the inside of the water guide flushing inner ring 504 through the circulating transport water pump 502 and the reflux capillary 503, and the circulating water is introduced from top to bottom into the upper material guide cone 211 through the water guide flushing inner ring 504, so as to assist in flushing the inner wall of the upper material guide cone 211 with the circulating water, so as to ensure that the raw materials inside the upper material guide cone 211 can slide down smoothly, and the raw materials mixing process inside the forming barrel 1 is replenished with water by spraying the water replenishing top ring 507 as the center;

[0099] While the formed raw materials enter the reflux separation side cylinder 4, a continuous upward circulating airflow is generated in the reflux separation side cylinder 4 through the bottom circulation fan 513. The continuous upward airflow reduces the friction between the formed bait and the top surface of the discharge fine hole circular plate 515, causing the bait to roll horizontally along the top of the discharge fine hole circular plate 515 to the discharge arc pipe 516, and then the raw materials moved to the top of the discharge fine hole circular plate 515 can be discharged from the reflux separation side cylinder 4 through the discharge arc pipe 516, and the formed bait is collected for subsequent processing;

[0100] When the bait passes through the top of the discharge porous circular plate 515, the rolling bait particles collide with each other during the rolling process to separate the small particles that are not firmly adhered to the outside of the bait. The small particle powder that falls off from the bait particles will rise along the inner wall of the reflux separation side tube 4 under the action of the airflow, and the small particle powder blown to the top will be intercepted by the isolation porous top net 510, and then the circular arc scraper 511 is driven to rotate by rotating the circulation motor 508 in conjunction with the central thin shaft 509. In the process of the rotation of the circular arc scraper 511, the small particle powder adhered to the bottom of the isolation porous top net 510 enters the reflux top duct 517 under the action of the airflow, and the recovered raw materials are guided back to the center forming barrel 1 through the reflux top duct 517, thereby realizing the circulation of the bait raw materials, and the inner wall of the reflux separation side tube 4 is scraped by the spiral scraper 512 to prevent the raw materials from adhering to the inside of the reflux separation side tube 4.

[0101] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
