Abstract
Description
Technical Field
[0001] This invention relates to a drying and dehumidification device, specifically a drying and dehumidification device for fermented aquatic feed production, belonging to the field of aquatic feed processing technology. Background Technology
[0002] Currently, fermented aquatic feed is a type of aquaculture feed that has undergone special microbial fermentation treatment. It is produced by fermenting conventional feed ingredients using beneficial microorganisms such as lactic acid bacteria and Bacillus. During fermentation, microorganisms decompose macromolecules in the feed, such as proteins and polysaccharides, and transform them into smaller molecules that are more easily absorbed and utilized by aquatic animals, such as small peptides, amino acids, and oligosaccharides. This not only improves the nutritional value and digestibility of the feed, but also reduces anti-nutritional factors in the feed, reducing irritation and damage to the intestines of aquatic animals. For example, fermentation can reduce trypsin inhibitors in soybean meal, allowing fish to better digest and utilize the protein. At the same time, the fermentation process can also produce some beneficial metabolites, such as vitamins and organic acids, which help improve the intestinal health and immunity of aquatic animals. In addition, fermented aquatic feed has better palatability, which can stimulate the appetite of aquatic animals and increase their feed intake and growth rate. The drying and dehumidification of fermented aquatic feed refers to the process of removing excess moisture from the feed and creating a suitable drying environment during the production of fermented aquatic feed using specific technologies and equipment to ensure the quality and storage stability of the feed. During the drying process, hot air or other heating methods are used to evaporate the moisture from the feed.
[0003] A search revealed a Chinese patent with publication number CN217844568U, which discloses a drying device for aquatic feed processing. The device includes a drying box, a drying cylinder, and a control box. The drying cylinder is housed within the drying box and is rotatably mounted on the drying box via bearings at its upper and lower ends. Two bearings are respectively embedded in the middle of the top and bottom of the drying box. The upper feed inlet and lower discharge outlet of the drying cylinder extend out of the drying box, and a second gear is installed at the upper end of the drying cylinder. Two elongated air nozzles are symmetrically installed on both sides of the drying box via fixed rods. A feed hopper is mounted on the left side of the top of the drying box via a bracket, and a rotary motor is installed on the right side of the top of the drying box. The output shaft of the rotary motor passes through the top of the drying box and is fitted with a first gear, which meshes with the second gear. This invention dries the feed by heating external air and blowing it onto the rotating drying cylinder, achieving uniform heating and improving the feed drying effect.
[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:
[0005] In practical applications, the aforementioned equipment uses a fan to assist in drying, while also employing a natural descent method to aid the drying process. Although this method can achieve a certain drying effect, it has significant drawbacks in actual processing. The natural descent method results in a rapid feed discharge speed, often with feed quickly leaking out of the equipment within a few seconds. However, it is clearly difficult to achieve effective drying with hot air in such a short time, as the hot air cannot fully exert its effect and achieve the desired drying result. Furthermore, during the natural descent process, the feed inevitably clumps and piles up. In this situation, even with hot air assistance, the tightly packed internal structure of the clumps or piles makes it difficult for hot air to penetrate, thus hindering thorough and uniform drying. Summary of the Invention

Both the interior of the exhaust slot and the interior of the hot air exhaust pipe are equipped with a mesh to prevent fermented feed from entering.
[0019] This invention provides a drying and dehumidification device for fermented aquatic feed production, which has the following beneficial effects:
[0020] 1. This equipment is equipped with a drive mechanism. After feed is added to the tank from the feed hopper, the drive motor is started to drive the rotating shaft, which causes the stirring auger to rotate clockwise and drive the feed downward. Due to the extrusion of the stirring auger, the feed enters the side cylinder through the inlet trough. At the same time, the drive motor causes the gear ring to rotate, which is redirected by the transmission gear set to drive the drive gear to rotate, causing the lifting auger to reverse and send the feed from the side cylinder upward, and then back to the top of the tank from the discharge trough. This cycle keeps the feed flowing up and down. The rotating shaft also drives the scraper side plate and the stirring plate to rotate, which helps to tumble and disperse the feed, improving the uniformity of mixing. Hot air is evenly discharged into the tank. Because the mixing inside the tank is uniform, the feed can be fully and stably exposed to the hot air, improving the drying efficiency and uniformity. Compared with existing equipment, this equipment can dry continuously without interruption, and the effect is more thorough and comprehensive.
[0021] 2. This equipment is equipped with a hot air supply and circulation mechanism. During drying, the feed valve is first activated to close the feed hopper and prevent waste gas from being discharged. The waste gas exhaust pipe is then connected to the external purification equipment. The drive unit is then activated, followed by the hot air blower. The generated hot air passes through the drying pipe rack to the hot air exhaust pipe and is discharged into the tank. The hot air exhaust pipes are arranged linearly at equal intervals on the outer surface of the tank, ensuring that the hot air makes uniform and comprehensive contact with the aquatic feed, improving the drying uniformity and effect. Multiple hot air blowers ensure the supply of hot air. The dried air passes through the exhaust duct to the exhaust pipe rack, and then through the ring pipe and the waste gas exhaust pipe to the external treatment equipment. The exhaust pipe rack spirals and covers the tank. The heat energy of the waste gas during circulation acts on the tank, reusing the heat energy, reducing waste, and improving drying efficiency.
[0022] 3. By incorporating a movable mechanism, the system utilizes the power of a drive motor for auxiliary driving during operation. The power generated by the drive motor not only drives the internal material mixing, drying, and vertical conveying, but also rotates a half-gear. This half-gear meshes with a rack. When the half-gear and rack mesh, the frame moves to one side. As the half-gear rotates, it alternately drives another rack on the opposite side, in the opposite direction. This drives the movable frame in the opposite direction. Therefore, as the drive motor operates, it can drive... The entire frame moves left and right, and because the base plate slides against the bottom rail and movable plate, the entire tank and other structures of the equipment are slidably connected to the top of the base plate. The frame and the base plate are connected, and the base plate is placed on the ground. At this time, the entire tank can be driven to swing left and right in the opposite direction. During this period, the rollers can reduce friction, so that the entire equipment can be in a state of left and right swinging during the drying process. This can further shake the material inside the tank, making it more violently agitated and promoting better tumbling and drying, which can further improve the overall drying efficiency.

[0048] The hot air supply mechanism 3 and the staggered hot air circulation mechanism 6 equipped on the outside of the tank 4 can effectively ensure that the hot air acts evenly and comprehensively on the feed inside the tank 4, significantly improving the uniformity and efficiency of drying, while maximizing the reuse of heat energy and reducing waste. The discharge component 7 facilitates the control of feed discharge. The drive mechanism 9 at the top of the top cover 8 is fixedly connected to the stirring mechanism 10 at the bottom, enabling the stirring mechanism 10 to operate efficiently inside the tank 4, fully stirring the feed and ensuring it is heated evenly, thereby improving the drying and dehumidification effect. In addition, the circulation components 11 fixedly installed at the corners of the tank 4 further promote internal heat exchange and material circulation, which helps to dry and dehumidify more thoroughly, improving production quality and efficiency.
[0049] Please refer to Figures 1-4 and Figures 8-9 The circulation component 11 includes a side cylinder 111, which is fixedly installed at the four corners of the tank body 4. The bottom of the side cylinder 111 is fixedly connected to the top of the support leg 2. An inlet groove 112 is provided at the bottom of the side cylinder 111, and the input end of the inlet groove 112 is connected to the bottom of the tank body 4. A discharge groove 113 is provided at the upper inner side of the side cylinder 111, and the output end of the discharge groove 113 is connected to the inside of the tank body 4. A lifting auger 114 is rotatably connected inside the side cylinder 111. The top of the lifting auger 114 is fixedly connected to the bottom of the drive mechanism 9. The drive mechanism 9 includes a mounting frame 91, a transmission gear set 92, and a drive gear 93. The mounting frame 91 is fixedly installed on the top of the top cover 8. A drive motor 95 is fixedly installed on the top of the mounting frame 91. A gear ring 94 is fixedly installed through the mounting frame 91 at the output end of the drive motor 95. The transmission gear set 92 is rotatably connected to the four corners of the top of the top cover 8.
[0050] The transmission gear set 92 is divided into two meshing transmission gears. The driving gear 93 is rotatably connected to the top of the top cover 8. There are four groups of driving gears 93, which are respectively arranged at the positions corresponding to the tops of the side cylinders 111. The driving gear 93 is meshed and connected with the outer transmission gear in the transmission gear set 92. The tooth ring 94 is meshed and connected with the inner transmission gear in the transmission gear set 92. The upper end of the shaft body of the lifting auger 114 penetrates through the top cover 8 and is fixedly connected to the bottom of the driving gear 93. In the circulation component 11, the side cylinders 111 are fixed at the four corners of the tank body 4. The inlet slot 112 opened at the bottom can communicate with the inner bottom of the tank body 4. The discharge slot 113 at the upper end of the inner side is also connected to the inside of the tank body 4. The lifting auger 114 rotatably connected inside can realize the circulating transportation of materials. This design enables the materials to flow orderly between the tank body 4 and the side cylinders 111, ensuring the uniformity and comprehensiveness of the heat received by the materials. In the driving mechanism 9, the mounting frame 91 provides a stable mounting position for the driving motor 95.
[0051] The tooth ring 94 at the output end of the driving motor 95 transmits power to the driving gear 93 through the transmission gear set 92, thereby driving the lifting auger 114 to rotate. The setting of the transmission gear set 92 realizes the steering and distribution of power, enabling the driving motor 95 to effectively control the operation of multiple lifting augers 114 at the same time. At the same time, it also makes the rotation directions of the lifting auger 114 and the stirring auger 102 opposite, realizing a good circulation of feed, which is beneficial to the upper and lower ranges of the feed. This design with a compact structure and efficient power transmission not only improves the operating stability of the equipment but also reduces energy loss, ensuring that the entire device can work continuously, stably, and efficiently, thereby improving the effect and quality of the production, drying, and dehumidification of fermented aquatic feed.
[0052] Embodiment 2
[0053] Please refer to Figure 1 、 Figures 8-10 On one side of the top of the top cover 8, a feed valve 12 is fixedly installed. On the top of the feed valve 12, a feed pipe 13 is fixedly installed. On the top of the feed pipe 13, a feed hopper is fixedly installed. The stirring mechanism 10 includes a rotating shaft 101. The rotating shaft 101 is rotatably connected to the bottom of the top cover 8. The top of the rotating shaft 101 is fixedly connected to the output end of the driving motor 95. A stirring auger 102 is fixedly installed on the outer surface of the rotating shaft 101. The inner bottom of the tank body 4 is conical. The lower end of the stirring auger 102 is also conical. Scraping side plates 103 are fixedly installed at equal intervals on the upper end of the outer surface of the rotating shaft 101. The lower end of the scraping side plates 103 is in a '丿' shape. Stirring rods are fixedly installed at equal intervals on the inner side of the scraping side plates 103.
[0054] The movable mechanism 14 includes a base plate 149 and a half gear 141. The half gear 141 is fixedly installed on the outer side of the shaft at the output end of the drive motor 95. The half gear 141 is located on the upper end of the gear ring 94. Two sets of slide rails 142 are fixedly installed on the top of the base plate 149. A movable plate 143 is slidably connected inside the slide rails 142. The top of the movable plate 143 is fixedly connected to the bottom of the base plate 1. A square groove 144 is opened in the middle of the base plate 1. Rollers 145 are rotatably connected at equal intervals inside the square groove 144. The bottom of the rollers 145 is in contact with the top of the base plate 149. Both sides of the top of the base plate 149 are fixed. A fixed arm 146 is installed, and a frame 147 is fixedly installed on the inner side of the fixed arm 146. Racks 148 are fixedly installed at both ends of the inner side of the frame 147. The inner side of the racks 148 meshes with a half gear 141. The half gear 141 is fixedly installed on the outer side of the shaft at the output end of the drive motor 95, ensuring direct and efficient power transmission. It can accurately convert the power of the drive motor 95 into the rotation of the half gear 141, thereby driving the subsequent transmission process, reducing energy loss and improving power utilization efficiency. Two sets of slide rails 142 are fixedly installed on the top of the base plate 149, and a movable live rail is slidably connected to them. The movable plate 143 provides a reliable guarantee for the smooth movement of the entire device. This sliding structure not only allows the device to move more stably from side to side during operation, but also reduces resistance during movement, reduces wear between components, and extends the service life of the device. The rollers 145, which are rotatably connected at equal intervals within the square groove 144 in the middle of the base plate 1, greatly reduce friction. This means that the driving energy required during device operation is reduced, and the heat generated by friction of components is also reduced, reducing the risk of thermal deformation and further ensuring the accuracy and stability of the device operation. Base plate 1 The combination of the fixed arms 146 fixedly installed on both sides of the top of the 49, and the inner frame 147 and rack 148, enables the meshing transmission of the half gear 141 and rack 148 to be precise and stable, thereby realizing the left and right movement of the tank 4. This ensures the regularity and controllability of the shaking of the tank 4. The movement of the tank 4 can further promote the tumbling of the material, which helps to improve the consistency and reliability of the drying effect. In summary, the ingenious design of this moving mechanism 14 and the synergistic effect of various components make the entire drying equipment more efficient, stable and energy-saving during operation, thus improving the performance and use value of the equipment.

The combination of the feed valve 12, feed pipe 13 and feed hopper on one side of the top of the top cover 8 facilitates the addition of feed. The feed valve 12 can effectively control the feed amount and feeding timing. At the same time, it can seal the output end of the feed hopper to prevent drying exhaust gas from being discharged into the production workshop.
[0056] In the stirring mechanism 10, the rotating shaft 101 is connected to the drive motor 95, which drives the stirring auger 102 to rotate. The conical design of the bottom of the tank body 4 and the lower end of the stirring auger 102 is conducive to the flow of feed and uniform mixing. The scraping side plate 103 on the upper part of the outer surface of the rotating shaft 101 and the stirring rod on the inner side can further improve the mixing effect and make the feed fully mixed. In the discharge assembly 7, the cooperation of the discharge frame 71, the electric push rod 72 and the sealing plate 73, through the electric push rod 72 to control the sealing plate 73, achieves precise discharge and ensures smooth and controllable discharge. These designs work together to improve the overall performance of the device, making the production, drying and dehumidification process of fermented aquatic feed more efficient, stable and controllable, and improving the overall processing efficiency and drying uniformity.
[0057] Example 3
[0058] Please refer to Figures 1-7 The hot air supply mechanism 3 includes three sets of mounting plates 31, which are fixedly installed on both sides and the middle of the rear side of the top frame 5. A hot air blower 32 is fixedly installed on the outer side of the mounting plate 31. A drying pipe rack 33 is fixedly installed at the output end of the hot air blower 32. The drying pipe rack 33 is fixedly installed on both sides and the middle of the back of the tank 4. Hot air pipes 34 are fixedly installed at equal intervals on the inner side of the drying pipe rack 33. The inner output end of the hot air pipes 34 is connected to the inside of the tank 4. The hot air circulation mechanism 6 includes an exhaust pipe rack 61, which is spirally installed on the outer surface of the tank 4. The exhaust pipe rack 61 and the hot air pipes 34 are arranged in an alternating manner.
[0059] Four sets of exhaust ducts 62 are evenly spaced on the upper inner side of the exhaust duct frame 61. The exhaust ducts 62 are connected to the upper inner end of the tank body 4. An annular pipe 63 is fixedly installed at the bottom of the exhaust duct frame 61. An exhaust gas delivery pipe 64 is fixedly installed on the rear side of the annular pipe 63. A connecting flange 65 is fixedly installed at the rear output end of the exhaust gas delivery pipe 64. The interior of the exhaust ducts 62 and the interior of the hot air exhaust pipe 34 are equipped with mesh screens to prevent fermented feed from entering. In the hot air supply mechanism 3, three sets of mounting plates 31 are fixed on the top. The sides and rear center of frame 5 provide stable support for the hot air blower 32. The hot air generated by the hot air blower 32 is delivered to the sides and rear center of tank 4 through the drying pipe frame 33. The hot air exhaust pipes 34 with equal spacing inside the tank ensure that the hot air enters the tank 4 evenly, ensuring that the feed in the tank 4 is heated comprehensively and evenly, effectively improving the drying efficiency. In the hot air circulation mechanism 6, the exhaust pipe frame 61 is spirally installed on the outer surface of the tank 4 and is staggered with the hot air exhaust pipes 34, which greatly improves the heat energy utilization efficiency.
[0060] The exhaust duct 62 at the upper inner end is connected to the upper inner end of the tank 4 to discharge exhaust gas in a timely manner. The annular pipe 63 at the bottom and the exhaust gas delivery pipe 64 at the rear can effectively export exhaust gas. The connecting flange 65 facilitates connection with external processing equipment. The mesh inside the exhaust duct 62 and the hot air exhaust pipe 34 can prevent fermented feed from entering the interior of each pipe, ensuring the normal operation of the mechanism and avoiding feed waste and equipment blockage. It is particularly worth mentioning that the hot air exhaust pipe 34 is arranged on the outer surface of the tank 4. When the dried exhaust gas enters the exhaust pipe rack 61 through the exhaust duct 62, the heat energy still contained in the exhaust gas can act on the tank 4, realizing the reuse of heat energy, reducing energy waste, and making the entire drying and dehumidification process more efficient, energy-saving, stable and reliable.
[0061] The implementation principle of the fermented aquatic feed production drying and dehumidification device in this application embodiment is as follows: By setting a drive mechanism 9, the feed to be dried can be added to the tank 4 from the feed hopper during the drying operation. After the feed is added to the tank 4, the drive motor 95 is started. The drive motor 95 drives the rotating shaft 101 to rotate. The rotation of the rotating shaft 101 causes the stirring auger 102 to rotate clockwise. When the stirring auger 102 rotates clockwise, it drives the feed inside the tank 4 to flow downward. In this process, due to the squeezing action of the stirring auger 102, the feed can flow into the side cylinder 111 through the inlet trough 112. At the same time, the drive motor 95 drives the gear ring 94 to rotate. The power of the gear ring 94 is transmitted through the two sets of transmission gears of the transmission gear set 92 and changes direction. At this time, it can drive the drive gear 93 to rotate. Due to the change in the direction of the transmission gear set 92, the rotation directions of the gear ring 94 and the drive gear 93 are opposite. When the stirring auger 102 rotates clockwise... Meanwhile, the drive gear 93 drives the lifting auger 114 to rotate in the reverse direction inside the side cylinder 111. Through the reverse rotation of the lifting auger 114, the feed inside the side cylinder 111 can be conveyed upward. After the feed moves upward, it can be synchronously discharged back into the upper part of the tank 4 from the discharge chute 113. This cycle is repeated, which can promote the stable up and down circulation of materials. Moreover, during this process, the rotating shaft 101 drives the scraper side plate 103 and the stirring plate inside it to rotate, which can further assist in the feeding inside the tank 4. The equipment tumbles, breaks up, and agitates the feed to effectively improve its uniformity. At this time, hot air is evenly discharged into the tank 4 through the hot air supply mechanism 3. Due to the uniform agitation inside the tank 4, the feed can come into full and stable contact with the hot air, thereby significantly improving its drying efficiency and drying uniformity. Meanwhile, during the drying process, the feed can be continuously dried by circulating it up and down throughout the process. Compared with existing equipment, this equipment can achieve multiple continuous and uninterrupted drying processes, resulting in a more thorough and comprehensive overall drying effect.
[0062] By setting up a hot air supply mechanism 3 and a hot air circulation mechanism 6, during the drying process, the feed valve 12 can be activated to close the feed hopper to prevent the exhaust gas after drying from being discharged through the feed hopper. At this time, the connecting flange 65 of the exhaust gas discharge pipe 64 is connected to the external exhaust gas treatment and purification equipment. Then, the drive equipment is started to drive the stirring mechanism 10 and the circulation component 11. Next, the hot air blower 32 is started. The hot air generated by the hot air blower 32 is discharged into each hot air discharge pipe 34 through the drying pipe rack 33. Each hot air discharge pipe 34 is arranged linearly with equal spacing on the outer surface of the tank 4. At this time, through the guidance and conveying of the hot air discharge pipes 34, the drying hot air can be evenly discharged into the tank 4, so that the hot air can come into more even and comprehensive contact with the aquatic feed, effectively improving its drying uniformity and effect. The configuration of the hot air blower 32 can provide a stable and reliable supply of drying hot air, significantly improving the efficiency of hot air drying. After drying, the air enters the exhaust pipe frame 61 through the exhaust duct 62, and is then guided to the external exhaust gas treatment equipment through the exhaust pipe frame 61, the annular pipe 63 and the exhaust gas delivery pipe 64. During this process, the exhaust pipe frame 61 is coiled and wrapped around the outer surface of the tank 4. When the exhaust gas flows inside the exhaust pipe frame 61, the heat energy inside the exhaust gas can continuously act on the tank 4, maximizing the reuse of drying heat energy, reducing heat energy waste, and thus improving drying efficiency. After the equipment has finished drying, the sealing plate 73 can be pulled out by starting the electric push rod 72. The sealing plate 73 is pulled away from the discharge frame 71, and the discharge frame 71 and the bottom output end of the tank 4 are connected, so that the processed aquatic feed can be discharged.
[0063] By setting the movable mechanism 14, the power generated by the drive motor 95 can be fully utilized for auxiliary drive during use. At this time, the power generated by the drive motor 95 can not only drive the stirring, drying, and vertical conveying of materials inside the entire equipment, but also drive the half gear 141 to rotate. The half gear 141 is in a meshing connection with the rack 148. When the half gear 141 and the rack 148 are meshed, the frame 147 can be driven to move to one side. As the half gear 141 continues to rotate, the half gear 141 will alternately drive the other rack 148 on the other side. The transmission direction of the other rack 148 is opposite to that of the previous rack 148. Therefore, with the operation of the drive motor 95, it can... Correspondingly, the entire frame 147 is driven to move left and right. Since the base plate 1 is slidably connected to the movable plate 143 through the bottom slide rail 142, the entire structure of the equipment, including the tank 4, is slidably connected to the top of the base plate 149. The frame 147 is also connected to the base plate 149, and the base plate 149 is placed stably on the ground. Therefore, the entire tank 4 can be driven to swing left and right in the opposite direction. During this period, the clever arrangement of the rollers 145 can effectively reduce friction. This allows the entire equipment to be in a state of left and right swaying during the drying process, which can further shake the material inside the tank 4, making it more violently agitated and allowing the material to tumble and dry better, thereby significantly improving its overall drying efficiency.
