Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a continuous low-pressure superheated steam drying device for seafood processing. Background Technology

[0002] Superheated steam drying equipment utilizes high-temperature, low-pressure superheated steam as the heating medium, enabling rapid and uniform drying of various materials. It is widely used in food processing (e.g., dried fruit, seafood, condiments), chemical production (e.g., catalysts, polymers), and pharmaceuticals (e.g., traditional Chinese medicine, raw materials for Western medicine). Superheated steam drying equipment performs exceptionally well for products requiring strict quality and nutritional content control, ensuring the high quality and stability of the final product.

[0003] Existing superheated steam drying equipment typically stores materials in a sealed chamber for drying due to the need for operation in a low-pressure environment. After drying, the sealed chamber is opened to remove the dried material. However, this process of opening and closing the sealed chamber results in significant heat loss. When a new batch of material needs to be dried again, the pressure and temperature inside the chamber must be slowly restored to the specified level, leading to low drying efficiency.

Liquid is filled in the third fixed shell, the second fixed shell and the pipe between them. The sliding rod is provided with a sliding push rod, which slides inside the third fixed shell.

[0010] Preferably, the discharge mechanism includes: The discharge shell is fixedly connected to and communicates with the drying box. The drying box has a storage cavity on the side away from the second guide shell. The storage cavity of the drying box is used to collect the material on the conveying unit. The discharge shell is communicated with the storage cavity of the drying box. The second electric push rod is fixedly connected to the drying box. The telescopic end of the second electric push rod is fixedly connected to a sliding shell. The sliding shell slides inside the discharge shell and is used to alternately communicate with the discharge shell.

[0011] Preferably, the discharge shell is slidably provided with a baffle, and the baffle is fixedly connected to the sliding shell, the baffle being used to block the discharge shell.

[0012] Preferably, the fixing plate is provided with a vertical groove, the vertical groove is connected to the adjacent inclined groove, the n-shaped frame is slidably connected to the adjacent first sliding frame, and a tension spring is installed between the n-shaped frame and the adjacent first sliding frame.

The air pressure inside the drying chamber is regulated to maintain stable pressure and improve energy efficiency. A fixed block intermittently limits the sliding block, controlling the reciprocating vibration of the oscillating plate to help distribute the material evenly within the three guide channels of the first guide shell. Simultaneously, the oscillating plate shakes and discharges the material, preventing adhesion between materials and ensuring uniform contact between the subsequent superheated steam and the material, thus achieving uniform drying. A rotating frame rotates and compresses the material on adjacent conveying units, helping to loosen the material and allowing superheated steam to flow evenly through the gaps between the materials, resulting in uniform drying.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example 1: A continuous low-pressure superheated steam drying device for seafood processing, such as... Figures 1-5As shown, the device includes: a drying chamber 1, with a door at the front; a drying system, a control system, and three conveying units 11; each conveying unit 11 consists of two rotating rollers and a drive belt; the six rotating rollers in the three conveying units 11 are sequentially connected by pulleys and belts; the drive belt has evenly distributed through holes for superheated steam to pass through; the control system controls the electrical components of the device; the drying system regulates the temperature and pressure inside the drying chamber 1 and guides the superheated steam to circulate within the drying chamber 1; and a drive motor 1 is installed in the drying chamber 1. 11. A drive motor 111 is fixedly connected to the rotating roller on the adjacent conveying unit 11. The drive motor 111 is used to drive all the conveying units 11 to rotate counterclockwise synchronously. A first guide shell 12 is fixedly connected to the right side of the upper surface of the drying chamber 1. Two partition plates 13 are fixedly connected inside the first guide shell 12. The upper surface of the partition plates 13 is provided with an inclined surface. The two partition plates 13 and the first guide shell 12 form three guide channels. A second guide shell 14 is fixedly connected inside the drying chamber 1. The second guide shell 14 is used to convey the materials in the three guide channels to the corresponding conveying units 11. A sliding plate 15 is slidably disposed on the first guide shell 12. The first guide shell 12 is provided with two stepped grooves 121. When the sliding plate 15 is located in the stepped groove 121, the two form an L-shaped sealing surface to improve the sealing performance between them. The sliding plate 15 is fixedly connected to three n-shaped frames 16. The n-shaped frames 16 are provided with a first sliding frame 17. The lower part of the first sliding frame 17 is rotatably and sealingly provided with a swing plate 18. The right side of the swing plate 18 is provided with an arc-shaped surface. The upper side of the partition plate 13 is provided with an inclined surface. The lower side of the inclined surface of the partition plate 13 is provided with an arc-shaped surface that contacts and cooperates with the adjacent swing plate 18. The first sliding frame 17 and the adjacent swing plate 18 are used to block the adjacent guide channels. A sealing strip 181 is fixed to the side away from the adjacent first sliding frame 17. The cross-section of the sealing strip 181 is triangular. When the swing plate 18 swings upward from the horizontal state, the swing plate 18 swings so that the sealing strip 181 on it is in close contact with the adjacent partition plate 13 (the rightmost sealing strip 181 is in contact with the first guide shell 12), which limits the swing range of the corresponding swing plate 18. At the same time, the sealing strip 181 deforms and fits the adjacent partition plate 13, which enhances the sealing between the two. The first guide shell 12 is provided with a drive mechanism for adding material into the drying box 1 in a closed manner. The drying box 1 is provided with a discharge mechanism for discharging the dried material in a closed manner.

[0020] like Figure 1 and Figure 4As shown, the driving mechanism includes: a first fixed shell 2, fixedly connected to the first guide shell 12, the first fixed shell 2 is in contact with the sliding plate 15, the upper surface of the first fixed shell 2 is composed of two inclined surfaces, the two inclined surfaces of the first fixed shell 2 gradually move away from each other from top to bottom; a first electric push rod 21, fixedly connected to the inner side of the first fixed shell 2; a second fixed shell 22, fixedly connected to the upper surface of the sliding plate 15, the telescopic end of the first electric push rod 21 is located in the second fixed shell 22 and slides in a sealed manner, and a spring is installed between the second fixed shell 22 and the telescopic end of the first electric push rod 21; and a swing assembly, disposed on the sliding plate 15, the swing assembly is used to control the swing range of the swing plate 18, and by controlling the reciprocating extension and retraction frequency of the first electric push rod 21, the speed of the material added to the drying chamber 1 is controlled, and in conjunction with the adjustment of the rotation speed on the conveying unit 11, it is convenient for this device to select different drying rates for different materials, thereby improving the versatility of this device.

[0021] like Figure 4 and Figures 6-8 As shown, the swing assembly includes: a sliding rod 3, which is slidably mounted on the sliding plate 15; a second sliding frame 31, which is slidably mounted on the lower part of the sliding rod 3; three third sliding frames 32 are slidably mounted on the lower part of the second sliding frame 31; springs are installed between the third sliding frames 32 and the second sliding frames 31; initially, the springs of the third sliding frames 32 and the second sliding frames 31 are in a charged state, causing the third sliding frames 32 to drive the swing plate 18 to swing until the corresponding sealing strip 181 deforms and fits against the adjacent partition plate 13 (while the rightmost sealing strip 181 contacts the first guide shell 12); the third sliding frames 32 are rotatably connected to the adjacent swing plates 18; and four fixed plates 33 are fixedly connected to the sliding plate 15 (this number can be set according to actual needs; the number of four is used to improve the stability of the second sliding frame 31); the four fixed plates 33 are distributed in a rectangular shape. The fixed plate 33 is provided with an inclined groove 331, which is inclined from top to bottom and to the left. The second sliding frame 31 is located in the inclined groove 331. The third fixed shell 34 is fixed to the upper surface of the sliding plate 15. The third fixed shell 34 and the second fixed shell 22 are connected by a pipe. Liquid is filled in the third fixed shell 34, the second fixed shell 22 and the pipe between them. The sliding rod 3 is provided with a sliding push rod 35, which slides in the third fixed shell 34. By controlling the extension length of the telescopic end of the first electric push rod 21, the second sliding frame 31 is positioned at a specified position on the inclined groove 331, thereby controlling the swing angle of the swing plate 18. Combined with the control of the rotation speed of the conveying unit 11, this device can control the thickness of the material on the conveying unit 11, so that the device can control the thickness of the material for different material conditions to select the best drying efficiency.

[0022] like Figure 2 and Figure 9As shown, the discharge mechanism includes: a discharge shell 4, fixedly connected to and connected to the left side of the drying chamber 1, the left side of the drying chamber 1 is provided with a storage chamber, the storage chamber of the drying chamber 1 is used to collect materials on the conveying unit 11, the storage chamber of the drying chamber 1 is used to store materials and pre-cool the materials, and the discharge shell 4 is connected to the storage chamber of the drying chamber 1; a second electric push rod 41, fixedly connected to the left side of the drying chamber 1, the telescopic end of the second electric push rod 41 is fixedly connected to a sliding shell 42 located inside the discharge shell 4, the sliding shell 42 is used to alternately communicate with the discharge shell 4, further reducing heat loss in the drying chamber 1, and at the same time the sealed discharge of materials facilitates continuous drying of materials by this device and improves the drying efficiency of this device; the discharge shell 4 is slidably provided with a baffle 43 for sealing the discharge shell 4, and the baffle 43 is fixedly connected to the sliding shell 42.

[0023] Specific working principle: When drying small batches of materials, the operator first opens the door of the drying chamber 1, then evenly adds the material to be dried onto the conveyor belts in the three conveying units 11. After the material is added, the operator closes the door of the drying chamber 1. Then, the operator starts the drying system through the control system on the drying chamber 1. The drying system adjusts the pressure inside the drying chamber 1 and simultaneously sprays superheated steam, which circulates within the drying chamber 1. During the circulation process, the superheated steam dries the material on the conveyor belts in the conveying units 11. After the material is dried, the operator closes the drying system through the control system and removes the material from the drying chamber 1.

[0024] When drying a large quantity of materials, the operator starts the drying system in the drying chamber 1, adjusts the temperature and pressure inside the drying chamber 1, and then adds a fixed amount of material into the first guide shell 12. The material falls onto the upper surface of the swing plate 18. After the material is added, the operator starts the first electric push rod 21 through the control system. The first electric push rod 21 drives the sliding plate 15 downward through the connected spring and the second fixed shell 22. The sliding plate 15 stops moving after it reaches the stepped groove 121. At this time, the sliding plate 15 completes the sealing of the first guide shell 12, and the material is located between the sliding plate 15 and the swing plate 18.

[0025] After the sliding plate 15 moves to the stepped groove 121, the telescopic end of the first electric push rod 21 continues to move downward. The telescopic end of the first electric push rod 21 will squeeze the connected spring and inject the liquid in the second fixed shell 22 into the third fixed shell 34 through the pipe. The liquid squeezes the sliding push rod 35, the sliding rod 3, and the second sliding frame 31 downward. The downward movement of the second sliding frame 31 is guided by the inclined groove 331. The second sliding frame 31 moves to the left relative to the sliding rod 3, so that the second sliding frame 31 moves to the left at the same time as it moves downward. The movement of the second sliding frame 31 causes the three swing plates 18 to swing and unload through the connected spring and the three third sliding frames 32. The oscillation mechanism causes the material located in the guide channel to fall through the second guide shell 14 onto the conveyor belts of the three conveying units 11. The control system in the drying chamber 1 starts the drive motor 111, which controls the three conveying units 11 to rotate counterclockwise. The rotation of the conveying units 11 evenly distributes the material on them. The circulating steam in the drying chamber 1 continuously dries the material during the movement. During the drying process, the control system controls the rotation speed of the drive motor 111 to control the drying time of the material conveyed on the conveying units 11, which allows the operator to select different drying times for different materials and improves the applicability of the device.

[0026] The dried material is conveyed by the transmission belt on the conveying unit 11 and falls into the storage chamber on the drying box 1. The telescopic end of the first electric push rod 21 moves upward and resets. The material in the storage chamber on the drying box 1 enters the sliding shell 42 through the discharge shell 4. The control system of the drying box 1 controls the second electric push rod 41 to move intermittently back and forth. The telescopic end of the second electric push rod 41 first drives the sliding shell 42 and the baffle 43 to move downward. The sliding shell 42 moves downward and gradually disconnects from the discharge shell 4. At the same time, the baffle 43 blocks the discharge shell 4, causing the dried material to gather near the baffle 43. Then the sliding shell 42 continues to move downward, so that the discharge shell 4 gradually releases the obstruction of the left opening on the sliding shell 42. The material in the sliding shell 42 falls from its left opening into the collection shell placed below it (existing equipment, which can be placed manually). Then the second electric push rod 41 moves in the opposite direction and resets. The above operation is repeated to continuously dry a large batch of material.

[0027] In the above drying process, the material is added to the drying chamber 1 in a closed manner, and the dried material is removed from the drying chamber 1 in a closed manner. This reduces the loss of heat and pressure in the drying chamber 1 and improves energy utilization. At the same time, the above operation allows the material to enter a stable and relatively constant closed chamber for drying, controlling the material to be heated evenly, thereby ensuring uniform drying. If the material to be dried needs to be dried in a constant temperature environment to avoid wrinkling and shrinkage of the material due to uneven drying, the same processing operation can be used when drying large quantities of material.

[0028] Example 2: Based on Example 1, such as Figures 5-7 As shown, the fixed plate 33 is provided with a vertical groove 332, which is located above the inclined groove 331. The vertical groove 332 is connected to the adjacent inclined groove 331. The n-shaped frame 16 and the adjacent first sliding frame 17 are slidably connected, and a tension spring is installed between the n-shaped frame 16 and the adjacent first sliding frame 17. In the initial state, the second sliding frame 31 is located in the middle of the vertical groove 332, and the tension spring between the n-shaped frame 16 and the adjacent first sliding frame 17 is in a stored state.

[0029] Specific working principle: During the drying process of a large quantity of materials, as the sliding plate 15 moves to the stepped groove 121, the telescopic end of the first electric push rod 21 continues to move downward. Guided by the vertical groove 332, the second sliding frame 31 and the three third sliding frames 32 move downward first. The third sliding frame 32 moves downward and squeezes the adjacent swing plate 18 and the adjacent first sliding frame 17 to move downward. After the second sliding frame 31 moves into the inclined groove 331, the material between the swing plate 18 and the sliding plate 15 is poured into the second guide shell 14. Then the above operation is repeated to dry the material.

[0030] During the process of adding materials into the drying chamber 1, the swing plate 18 moves downward relative to the sliding plate 15, thereby reducing the pressure between the swing plate 18 and the sliding plate 15. This allows the pressure added into the drying chamber 1 to be adjusted autonomously, keeping the pressure inside the drying chamber 1 relatively stable, further reducing resource consumption and improving the drying stability of the device.

[0031] Example 3: Based on Example 2, such as Figure 6 and Figure 8 As shown, it also includes: a fixed rod 5, fixed to the left side of the sliding rod 3; a sliding block 51, slidably disposed on the upper part of the fixed rod 5, the sliding block 51 having two inclined surfaces, the two inclined surfaces of the sliding block 51 gradually moving away from left to right, and a tension spring installed between the sliding block 51 and the fixed rod 5; a first fixed shell 2 fixedly having a plurality of evenly distributed fixed blocks 52, the fixed blocks 52 being used to change the motion state of the sliding block 51; the sliding rod 3 being slidably connected to the sliding push rod 35, and a spring installed between the sliding rod 3 and the sliding push rod 35; when the sliding push rod 35 moves down the length between two adjacent fixed blocks 52, the downward pressure exerted by the sliding push rod 35 on the sliding rod 3 by the connected spring is greater than the resistance force between the sliding block 51 and the fixed rod 5 under the tension of the adjacent tension spring.

[0032] Specific working principle: During the drying process of a large quantity of materials, as the sliding plate 15 moves downwards along with the connected parts, it is limited by the fixed block 52 on the sliding block 51. The sliding rod 3 initially remains stationary. As the sliding plate 15 moves downwards along with the third fixed shell 34 and the sliding push rod 35, the second sliding frame 31 moves upwards relative to the fixed plate 33. That is, the second sliding frame 31 moves upwards in the vertical groove 332. When the downward distance of the sliding plate 15 is equal to the length between two adjacent fixed blocks 52, it is limited by the fixed block 52. When pressed, the sliding block 51 moves to the right, stretching the connected spring, causing the sliding block 51 to pass through the fixed block 52. Subsequently, under the action of the spring connected to the sliding rod 3, the sliding rod 3 pops out downward. At the same time, under the elastic action of the tension spring connected to the sliding rod 3, the sliding rod 3 moves up and down reciprocally. The sliding rod 3 causes the swing plate 18 to move up and down reciprocally through the connected parts. The reciprocating movement of the swing plate 18 vibrates the material, making the material evenly distributed in the three material guide channels, thereby enabling the device to dry the material evenly and ensuring that the drying degree of the material in the same batch remains consistent.

[0033] When the swing plate 18 swings to unload material, the sliding block 51 passes through the remaining fixed blocks 52, causing the swing plate 18 to repeat the above-mentioned reciprocating shaking operation, so that the material falls evenly and loosely onto the transmission belt of the conveying unit 11, which facilitates the device to dry the material steadily and evenly.

[0034] Example 4: Based on Example 3, such as Figure 3 and Figure 10 As shown, it also includes: a rotating frame 6, of which there are six, the rotating frames 6 located on the same horizontal plane are grouped into three groups, and each group of rotating frames 6 is rotatably mounted on an adjacent conveying unit 11. The rotating frames 6 are used to press the transmission belt on the adjacent conveying unit 11; and a gearbox 61, of which there are three, all fixed to the rear side of the drying box 1. The transmission ratio of the gearbox 61 is set according to the requirements. The gearbox 61 is used to connect the adjacent conveying unit 11 and the adjacent rotating frame 6.

[0035] The specific working principle is as follows: During the drying process of the material, the rotation of the transmission rollers on the three conveying units 11 controls the rotation of the six rotating frames 6 through the three gearboxes 61. The rotation of the rotating frames 6 squeezes the transmission belts on the adjacent conveying units 11. This squeezing causes the material on the transmission belts of the conveying units 11 to shake and loosen, so that the superheated steam can pass evenly through the gaps in the material, thereby controlling the material to dry evenly and ensuring the quality of the dried material.

They should not be construed as limiting the scope of protection of the present invention.
