Description

Technical Field

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

[0002] The superheated steam drying device uses superheated steam with high temperature but low pressure as the heating medium, which can quickly and evenly dry various materials. It is widely used in food processing (such as dried fruits, seafood, condiments, etc.), chemical production (such as catalysts, polymers and other materials) and pharmaceuticals (such as Chinese herbal medicines, Western medicine raw materials, etc.). Especially for those products that require strict quality and nutritional content, the superheated steam drying device performs well, ensuring the high quality and stability of the final product.

[0020] like Figure 1 and Figure 4As shown, the driving mechanism includes: a first fixed shell 2, fixedly connected to the first material 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, and the two inclined surfaces of the first fixed shell 2 are gradually separated 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 for sealing and sliding, and a spring is installed between the second fixed shell 22 and the telescopic end of the first electric push rod 21; a swing assembly, arranged on the sliding plate 15, the swing assembly is used to control the swing range of the swing plate 18, and the speed of adding the material into the drying box 1 is controlled by controlling the reciprocating telescopic frequency of the first electric push rod 21, and then the rotation speed of the conveying unit 11 is adjusted, so that the device can select different drying rates for different materials and improve the diversity of the device.

[0021] like Figure 4 and Figure 6-Figure 8 As shown, the swing assembly includes: a sliding rod 3, which is sealed and slidably arranged on the sliding plate 15; a second sliding frame 31, which is slidably arranged at the lower part of the sliding rod 3, and three third sliding frames 32 are slidably arranged at the lower part of the second sliding frame 31, and a spring is installed between the third sliding frame 32 and the second sliding frame 31. In the initial state, the springs of the third sliding frame 32 and the second sliding frame 31 are in a power storage state, so that the third sliding frame 32 drives the swing plate 18 to swing until the corresponding sealing strip 181 is deformed and fits the adjacent partition plate 13 (and the sealing strip 181 on the far right is in contact with the first guide shell 12), and the third sliding frame 32 is rotatably connected to the adjacent swing plate 18, and the sliding plate 15 is fixed with four fixed plates 33 (the number can be set accordingly according to actual needs, and the setting of four is used to improve the working stability of the second sliding frame 31), and 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 to the left from top to bottom, and the second sliding frame 31 is located in the inclined groove 331; the third fixed shell 34 is fixedly connected to the upper surface of the sliding plate 15, and the third fixed shell 34 is connected to the second fixed shell 22 through a pipeline. The third fixed shell 34, the second fixed shell 22 and the pipeline therebetween are filled with liquid, and the sliding rod 3 is provided with a sliding push rod 35, which is located in the third fixed shell 34 and slides. By controlling the length of the telescopic end on the first electric push rod 21, the second sliding frame 31 is located at a specified position on the inclined groove 331, thereby controlling the swing angle of the swing plate 18, and then cooperating with the control of the rotation speed of the conveying unit 11, it is convenient for the device to control the thickness of the material on the conveying unit 11, that is, it is convenient for the device to control the material thickness under different material conditions to select the best drying efficiency.

[0022] like Figure 2 and Fig. 9As shown, the discharge mechanism includes: a discharge shell 4, which is fixedly connected and connected to the left side of the drying box 1, and a storage chamber is provided on the left part of the drying box 1. The storage chamber of the drying box 1 is used to collect materials on the conveying unit 11, and the storage chamber of the drying box 1 is used to store materials and pre-cool the materials. The discharge shell 4 is connected to the storage chamber of the drying box 1; a second electric push rod 41, which is fixedly connected to the left side of the drying box 1, and the telescopic end of the second electric push rod 41 is fixedly connected to a sliding shell 42 sliding in the discharge shell 4, and the sliding shell 42 is used to alternately connect with the discharge shell 4, so as to further reduce the heat loss in the drying box 1. At the same time, the sealed discharge of the material facilitates the continuous drying of the material by the device and improves the drying efficiency of the 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 a small batch of materials, the operator first opens the switch door on the drying box 1, and then the operator evenly adds the materials to be dried to the conveyor belts in the three conveying units 11. After the materials are added, the operator closes the switch door on the drying box 1, and then the operator starts the drying system through the control system on the drying box 1. The drying system works to adjust the pressure in the drying box 1. At the same time, the drying system sprays out superheated steam and circulates the superheated steam in the drying box 1. The superheated steam in the circulation process dries the materials on the conveyor belt in the conveying unit 11. After the materials are dried, the operator closes the drying system through the control system and takes the materials out of the drying box 1.

[0024] When drying a large amount of materials, the operator starts the drying system in the drying box 1, adjusts the temperature and pressure in the drying box 1, and then adds a certain amount of material into the first material guide shell 12, wherein the material falls to 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 to move downward through the connected spring and the second fixed shell 22, and stops moving after the sliding plate 15 moves to the step groove 121. At this time, the sliding plate 15 completes the blocking of the first material 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 step groove 121, the telescopic end of the first electric push rod 21 continues to move downward, and the telescopic end of the first electric push rod 21 squeezes the connected spring and injects the liquid in the second fixed shell 22 into the third fixed shell 34 through the pipeline. The liquid squeezes the sliding push rod 35, the sliding rod 3 and the second sliding frame 31 to move downward. The second sliding frame 31 moves downward under the guidance of 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 during the downward movement. The second sliding frame 31 moves through the connected spring and the three third sliding frames 32 to make the three swing plates 18 swing to unload, and the swing plate 18 swings to unload. 8 swings so that the materials in the material guide channel pass through the second material guide shell 14 and fall onto the conveyor belts of the three conveying units 11 respectively, wherein the control system in the drying box 1 starts the driving motor 111 to work, and the driving motor 111 controls the three conveying units 11 to rotate counterclockwise, and the conveying units 11 rotate to make the materials evenly distributed thereon, wherein the circulating steam in the drying box 1 continuously dries the materials in the moving process, and during the drying process, the rotation speed of the driving motor 111 is controlled by the control system to control the drying time of the materials conveyed on the conveying unit 11, so that the operator can select different drying times for different materials, thereby improving the applicability of the device.

[0026] The dried material is transported by the transmission belt on the conveying unit 11 and falls into the material storage chamber on the drying box 1. The telescopic end of the first electric push rod 21 moves upward and resets, and the material in the material storage chamber on the drying box 1 enters the sliding shell 42 through the discharge shell 4, wherein the control system of the drying box 1 controls the second electric push rod 41 to perform intermittent reciprocating movement, wherein the telescopic end of the second electric push rod 41 first drives the sliding shell 42 and the baffle 43 to move downward, and the sliding shell 42 moves downward and gradually releases the connection with the discharge shell 4, and at the same time the baffle 43 blocks the discharge shell 4, so that the dried material gathers near the baffle 43 side, and 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, and the material in the sliding shell 42 falls from its left opening to the collecting shell (existing equipment, manually placed) placed below it, and then the second electric push rod 41 moves in the opposite direction and resets, and then the above operation is repeated to continuously dry large quantities of materials.

[0027] In the above-mentioned drying process, the material is added into the drying box 1 in a closed manner, and the dried material is taken out from the drying box 1 in a closed manner, so as to reduce the loss of heat and pressure in the drying box 1 and improve the energy utilization rate. At the same time, the above-mentioned operation allows the material to enter a stable and relatively constant closed chamber for drying, and controls the material to be heated evenly, so that the material is dried evenly. If the dried material needs to be dried in a constant temperature environment, the wrinkles and shrinkage of the material due to uneven drying can be avoided. The above-mentioned processing operation can also be used when drying large quantities of materials.

[0028] Embodiment 2: Based on embodiment 1, Figure 5-Figure 7 As shown, the fixed plate 33 is provided with a vertical groove 332, the vertical groove 332 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 force state.

[0029] Specific working principle: During the drying process of large quantities of materials, as the sliding plate 15 moves to the step groove 121, the telescopic end of the subsequent first electric push rod 21 continues to move downward, and guided by the vertical groove 332, the second sliding frame 31 and the three third sliding frames 32 move downward first, and the third sliding frame 32 moves downward to squeeze the adjacent swing plate 18 and the adjacent first sliding frame 17. After the subsequent second sliding frame 31 moves into the inclined groove 331, the material between the swing plate 18 and the sliding plate 15 is dumped into the second material guide shell 14, and then the above operation is repeated to perform the material drying operation.

[0030] In the above process of adding materials into the drying box 1, the swing plate 18 moves downward relative to the sliding plate 15, so that the pressure between the swing plate 18 and the sliding plate 15 is reduced, and the pressure added to the drying box 1 is autonomously adjusted to keep the pressure in the drying box 1 relatively stable, further reducing resource consumption and improving the drying stability of the device.

[0031] Embodiment 3: Based on embodiment 2, Figure 6 and Figure 8 As shown, it also includes: a fixed rod 5, fixedly connected to the left side of the sliding rod 3; a sliding block 51, slidably arranged on the upper part of the fixed rod 5, the sliding block 51 is provided with two inclined surfaces, the two inclined surfaces of the sliding block 51 gradually move away from each other from left to right, and a tension spring is installed between the sliding block 51 and the fixed rod 5, the first fixed shell 2 is fixedly connected with a plurality of evenly distributed fixed blocks 52, the fixed block 52 is used to change the movement state of the sliding block 51, the sliding rod 3 is slidably connected to the sliding push rod 35, and a spring is 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 sliding push rod 35 compresses the connected spring acting on the sliding rod 3. The downward pressure is greater than the hindering force between the sliding block 51 and the fixed rod 5 under the tension of the adjacent tension springs.

[0032] Specific working principle: During the drying process of a large number of materials, the sliding plate 15 drives the connected parts to move downward, and the fixed block 52 limits the sliding block 51, wherein the sliding rod 3 remains stationary first, and the sliding plate 15 drives the third fixed shell 34 and the sliding push rod 35 to move downward. At this time, the second sliding frame 31 moves upward relative to the fixed plate 33, that is, the second sliding frame 31 is located in the vertical groove 332 and moves upward. When the sliding plate 15 moves downward by a distance equal to the length between two adjacent fixed blocks 52, the fixed block 52 limits the position of the sliding rod 31. The sliding block 51 is pressed to the right and the connected spring is stretched, so that the sliding block 51 passes through the fixed block 52. Subsequently, under the spring action of the spring connected to the sliding rod 3, the sliding rod 3 pops up downward. At the same time, under the elastic action of the tension spring connected to the sliding rod 3, the sliding rod 3 reciprocates up and down. The sliding rod 3 makes the swing plate 18 reciprocate up and down through the connected parts. The reciprocating movement of the swing plate 18 vibrates the material, so that the material is evenly distributed in the three material guide channels, so that the device can evenly dry the material, so as to keep the drying degree of the materials in the same batch consistent.

[0033] When the swing plate 18 swings to perform the unloading operation, the sliding block 51 passes through the remaining fixed blocks 52, so that the swing plate 18 repeats the above-mentioned reciprocating shaking operation, which makes it easier for the material to fall evenly and loosely onto the transmission belt of the conveying unit 11, so that the device can dry the material smoothly and evenly.

[0034] Embodiment 4: Based on the embodiment 3, Figure 3 and Fig.10 As shown, it also includes: a rotating frame 6, which has six pieces, and the rotating frames 6 located on the same horizontal plane are a group, and the six rotating frames 6 are divided into three groups, each group of rotating frames 6 is rotatably set on the adjacent conveying unit 11, and the rotating frames 6 are used to squeeze the transmission belts on the adjacent conveying units 11; there are three gear boxes 61, which are all fixed to the rear side of the drying box 1, and the transmission ratio of the gear box 61 is set according to the needs, and the gear box 61 is used to connect the adjacent conveying units 11 and the adjacent rotating frames 6.

[0035] Specific working principle: During the material drying process, the transmission rollers on the three conveying units 11 rotate through three gear boxes 61 to control the six rotating frames 6 to rotate. The rotating frames 6 rotate to squeeze the transmission belts on the adjacent conveying units 11. The squeezing causes the material on the transmission belts on the conveying units 11 to shake and loosen, making it easier for superheated steam to evenly pass through the gaps between the materials, thereby controlling the uniform drying of the materials and ensuring the quality of the materials after drying.

[0036] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
