Description

Technical Field

[0001] This utility model relates to the field of food production technology, and in particular to a drying device for producing jujube cake. Background Technology

[0002] Drying devices for jujube cake production are commonly used in daily jujube cake processing. They mainly undertake key tasks such as evaporating moisture, shaping the product, enhancing flavor, and extending shelf life, effectively ensuring product quality, optimizing production processes, and improving output efficiency. Publication number CN210203111U discloses a drying device for jujube cake production, relating to the field of food production technology. It includes a base and a partition. A shell is fixed above the base, and a holding mechanism is installed inside the shell. The holding mechanism includes a side plate, a slider, a slide rail, a holding plate, a protrusion, and a baffle. A slider is fixed to the front end of the side plate, and a slide rail is provided outside the slider. The holding plate is connected to the left side of the side plate. A protrusion is placed above the holding plate, and a baffle is fixed to the left side of the protrusion. A mesh opening is installed inside the partition, and the partition is located on the right side of the holding mechanism. A drying mechanism is fixed to the right side of the partition. The aforementioned drying device for jujube cake production has the advantages of facilitating the storage and retrieval of jujube cakes without requiring hands to be inserted into the excessively hot device. It can also classify and store jujube cakes according to their size, consumes little power during operation, and can recycle heat. This utility model, through the design of side plates, sliders, slides, a holding plate, protrusions, and baffles, can classify and store jujube cakes according to their size, consume little power during operation, and recycle heat. However, it cannot automatically clean the jujube cake holding plate after drying, leaving residual debris and sticky residue on its surface. This necessitates disassembling the holding plate or reaching inside the device to wipe and clean it after drying. Incomplete cleaning can lead to residue accumulation, which, during subsequent drying, can char and produce odors, contaminating new batches of jujube cakes and affecting product flavor and hygiene. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a drying device for producing jujube cake, including a drying box, a door hinge fixedly installed on the surface of the drying box, a door rotatably connected to the surface of the door hinge, a transparent window fixedly installed on the surface of the door, a baffle fixedly installed inside the drying box, an electric heating rod fixedly installed on the surface of the baffle, a motor A fixedly installed on the surface of the drying box, a lead screw A fixedly installed at the output end of the motor A, a slide rod A fixedly installed inside the drying box, a grid plate threadedly connected to the surface of the lead screw A, a slide rod block A fixedly installed on the surface of the grid plate, a motor B and a slide rod B fixedly installed on the surface of the grid plate, a lead screw B fixedly installed at the output end of the motor B, a chip removal frame threadedly connected to the surface of the lead screw B, a slide rod block B and a scraper fixedly installed on the surface of the chip removal frame, and a brush plate fixedly installed on the surface of the chip removal frame by screws.

[0005] Preferably, the length of the slide bar A is the same as the length of the lead screw A and they are symmetrically distributed on both sides of the grid plate. The surface of the slide bar A and the interior of the slide bar block A are slidably connected. Here, the grid plate is evenly stressed, avoiding unilateral offset or jamming, and ensuring that the grid plate can slide smoothly in the horizontal direction. This makes it convenient for operators to pull the grid plate out of the drying box to place the jujube cake, or to take it out smoothly after drying, without having to frequently bend over or go deep into the box, thus improving the ease of operation. The sliding structure has low frictional resistance, and the movement is smooth and wobbly, which can prevent the jujube cake from falling or scattering. Combined with the hollow design of the grid plate, it does not affect the heat conduction of the heating rod, and lays a stable foundation for subsequent chip removal operations, taking into account both practicality and operational safety.

[0006] Preferably, the length of the slide bar B is the same as the length of the lead screw B and they are symmetrically distributed on both sides of the chip removal frame. The surface of the slide bar B and the interior of the slide bar block B are slidably connected. Here, the chip removal frame is subjected to balanced force, and there will be no deviation or jamming during movement. This ensures that the scraper and brush on the frame can always be in close contact with the grid surface and move smoothly back and forth in the horizontal direction. This allows the scraper to accurately scoop up the blocky debris remaining after drying, while the brush simultaneously sweeps away fine powder and residue adhering to the grid gaps. The sliding structure has low resistance, and the chip removal frame can quickly complete a comprehensive cleaning, avoiding the accumulation of debris that will affect the next drying operation. This not only improves the grid cleaning efficiency but also ensures the hygienic quality of subsequent jujube cake production.

[0007] Preferably, the surface of the shovel and the surface of the grid plate are in contact, and the surface of the brush blade and the surface of the grid plate are in contact. This allows for precise shoveling of hardened, clump-like residue from the dried jujube cake, preventing lumpy residue from getting stuck in the grid gaps or adhering to the plate surface to form stubborn stains. The close contact of the brush blade allows for simultaneous cleaning of fine powder and adhesive debris from the grid surface and gaps, preventing debris from accumulating due to gaps and preventing scratches on the grid surface during cleaning. This ensures a clean and flat surface when placing jujube cakes later, preventing residual debris from affecting the drying quality and hygiene of the new batch of jujube cakes.

[0008] Preferably, a debris box is placed at the bottom of the drying chamber, a handle is fixedly installed on the surface of the debris box, a limiting groove is formed on the surface of the drying chamber, a spring groove is formed on the surface of the limiting groove, a spring is fixedly installed on the surface of the spring groove, and a limiting block is fixedly installed on the other end of the spring. Here, after the debris removal rack finishes cleaning the grid plate, the debris can fall directly into the debris box below, avoiding it from scattering inside the drying chamber and being difficult to clean, thus ensuring the hygiene of the chamber. The handle allows the operator to easily pull out the debris box to empty the waste material without the aid of tools, making the operation convenient and efficient. The limiting groove and the spring-driven limiting block can automatically lock and fix the debris box when it is pushed in, preventing the box from shifting or tipping over during the drying operation or equipment operation, which would cause debris to leak out. At the same time, it can be removed by simply pushing the limiting block, taking into account both the stability of the fixation and the convenience of loading and unloading, making the debris collection process both efficient and reliable, and providing a guarantee for the hygiene and safety of the subsequent jujube cake drying operation.

[0009] Preferably, the surface of the limiting block is arc-shaped, and the surface of the limiting block fits into the surface of the debris box. Two limiting grooves are symmetrically distributed on both sides of the debris box. Here, the curved surface allows for smooth pressure on the limiting block, causing it to automatically compress the spring and retract into the spring groove. This eliminates the need for manual operation, easily completing the box installation and avoiding jamming caused by right-angle structures. In the fitted state, after the box is in place, the limiting block, under the action of the spring force, tightly presses against the box body, forming a stable limit and preventing the box from shaking or shifting during equipment operation. The symmetrical limiting grooves on both sides further enhance the fixing effect, ensuring balanced force on the box body and avoiding tilting or displacement caused by unilateral limiting. This ensures no risk of spillage during debris collection and allows for easy removal of the debris box by simply pulling it out and pressing the limiting block again through the arc-shaped surface when emptying the waste. It balances stability and ease of operation, ensuring efficient and orderly debris collection.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a lead screw A, a slide bar A, a grid plate, a lead screw B, a slide bar B, a chip removal frame, a brush, and a scraper, the lead screw A, in conjunction with the slide bar A, drives the grid plate to move smoothly laterally, facilitating the quick placement of the jujube cake to be dried and the removal of the finished product. At the same time, the position of the grid plate can be adjusted to ensure uniform drying. After drying, the lead screw B and the slide bar B drive the chip removal frame to move smoothly along the grid plate. The scraper, which is in contact with the grid plate, first scrapes up the blocky residual chips, and then the brush simultaneously sweeps away the fine powder and residue in the grid gaps, avoiding chip accumulation that affects subsequent production, thus taking into account both production convenience and hygiene standards.

[0012] 2. In this utility model, by setting up a debris box, a pull handle, a limiting groove, a spring groove, a spring, and a limiting block, the debris can fall directly into the debris box below through the synergistic effect of these structures, achieving centralized collection and avoiding scattering into the drying chamber and causing cleaning dead corners. The limiting groove provides precise installation positioning for the debris box, and the spring in the spring groove provides continuous elasticity to the limiting block, making the limiting block fit tightly against the surface of the box, preventing the box from shifting or tipping over during equipment operation, which would cause debris to leak out. The box can be removed and the waste material disposed of by simply pulling and squeezing the arc-shaped limiting block. This not only ensures the stability and hygiene of debris collection, but also simplifies the cleaning operation process, providing a strong guarantee for a clean environment for subsequent jujube cake drying operations.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-4This utility model provides a technical solution: a drying device for producing jujube cake, including a drying chamber 1, forming a closed drying space to ensure that the heat generated by the heating rod 6 is not easily lost, maintaining a stable drying temperature environment inside the chamber, providing the basic conditions for efficient drying of jujube cake. A door hinge 2 is fixedly installed on the surface of the drying chamber 1, and a chamber door 3 is rotatably connected to the surface of the door hinge 2. A transparent window 4 is fixedly installed on the surface of the chamber door 3, allowing operators to directly observe the drying status of the jujube cake inside the drying chamber 1 without opening the chamber door 3, avoiding frequent opening of the door and causing heat loss, and facilitating timely detection of abnormalities during the drying process. A baffle 5 is fixedly installed inside the drying chamber 1, and a heating rod 6 is fixedly installed on the surface of the baffle 5. A motor A7 is fixedly installed, and a lead screw A8 is fixedly installed at the output end of the motor A7. A slide bar A9 is fixedly installed inside the drying chamber 1. The length of the slide bar A9 is the same as the length of the lead screw A8 and is symmetrically distributed on both sides of the grid plate 10. The surface of the slide bar A9 and the interior of the slide bar block A11 are slidably connected. Here, the grid plate 10 is evenly stressed, avoiding unilateral offset or jamming, and ensuring that the grid plate 10 can slide smoothly in the horizontal direction. This makes it convenient for operators to pull the grid plate 10 out of the drying chamber 1 to place the jujube cake, or to take it out smoothly after drying, without having to frequently bend over or go deep into the chamber, thus improving the convenience of operation. The sliding structure has low frictional resistance, and the movement is smooth and wobbly, which can prevent the jujube cake from falling or scattering. Combined with the hollow design of the grid plate 10, it does not affect the heating rod. The heat conduction of 6 provides a stable foundation for subsequent chip removal operations, balancing practicality and operational safety. A screw A8 is threadedly connected to a grid plate 10. A slide block A11 is fixedly mounted on the surface of the grid plate 10. A motor B12 and a slide rod B14 are also fixedly mounted on the surface of the grid plate 10. The length of the slide rod B14 is the same as that of the screw B13 and they are symmetrically distributed on both sides of the chip removal frame 15. The surface of the slide rod B14 and the interior of the slide block B16 are slidably connected. This ensures that the chip removal frame 15 is evenly stressed and will not shift or jam during movement. It also ensures that the scraper 19 and brush 18 on the frame can always be in close contact with the surface of the grid plate 10, moving smoothly back and forth in the horizontal direction. This allows the scraper 19 to accurately scrape up the remaining blocky debris after drying. Simultaneously sweeping away fine powder and residue adhering to the grid gaps, the sliding structure has low resistance, allowing the chip removal frame 15 to quickly complete a thorough cleaning, preventing chip accumulation from affecting the next drying operation. This improves the cleaning efficiency of the grid plate 10 and ensures the hygienic quality of subsequent jujube cake production. A lead screw B13 is fixedly installed at the output end of the motor B12, and the chip removal frame 15 is threaded onto the surface of the lead screw B13. A sliding block B16 and a scraper 19 are fixedly installed on the surface of the chip removal frame 15. A brush 18 is fixedly installed on the surface of the chip removal frame 15 by screws 17. The surfaces of the scraper 19 and the grid plate 10 are in contact, and the surfaces of the brush 18 and the grid plate 10 are also in contact. Here, the hardened and clump-forming residual chips of the jujube cake after drying can be precisely scraped up.To prevent lumpy residue from getting stuck in the grid gaps or adhering to the board surface to form stubborn stains, the brush blades 18 fit tightly together to simultaneously sweep away fine powder and adhesive debris from the surface of the grid plate 10 and the grid gaps. This not only prevents debris from accumulating due to gaps but also prevents scratches on the surface of the grid plate 10 during cleaning, ensuring a clean and flat surface when placing jujube cakes later, and avoiding residual debris affecting the drying quality and hygiene safety of the new batch of jujube cakes.

[0024] Example 2

[0025] Please see Figure 5 A debris box 20 is placed at the bottom of the drying oven 1 to collect debris falling from the shaving rack 15 after cleaning the grid 10, preventing debris from scattering inside the drying oven 1 and making it difficult to clean, thus ensuring the hygiene of the drying oven 1. At the same time, the collected debris is easy to dispose of in a unified manner later, reducing the amount of cleaning work. A handle 21 is fixedly installed on the surface of the debris box 20. A limit groove 22 is formed on the surface of the drying oven 1. A spring groove 23 is formed on the surface of the limit groove 22. A spring 24 is fixedly installed on the surface of the spring groove 23. A limit block 25 is fixedly installed on the other end of the spring 24. Here, after the chip removal frame 15 finishes cleaning the debris from the grid plate 10, the debris can fall directly into the debris box 20 below, preventing it from scattering inside the drying chamber 1 and becoming difficult to clean, thus ensuring the hygiene of the chamber's interior. The pull handle 21 allows operators to easily pull out the debris box 20 to empty the waste material without the need for tools, making operation convenient and efficient. The limiting groove 22 and the limiting block 25 driven by the spring 24 can automatically lock and fix the debris box 20 when it is pushed in, preventing the box from shifting or tipping during drying operations or equipment operation, which could cause debris to leak out. At the same time, disassembly can be done simply by gently pushing the limiting block 25. The design balances stability with ease of loading and unloading, ensuring efficient and reliable debris collection and guaranteeing hygiene and safety for subsequent jujube cake drying operations. The surface of the limiting block 25 is arc-shaped, fitting snugly against the surface of the debris box 20. Two limiting grooves 22 are symmetrically distributed on both sides of the debris box 20. Here, the curved surface allows for smooth compression of the limiting block 25, causing it to automatically compress the spring 24 and retract into the spring groove 23. This eliminates the need for manual operation, easily completing the box installation and avoiding jamming caused by right-angle structures. Once the box is in place, the limiting block 25, under the elastic force of the spring 24, tightly presses against the box body, forming a stable limit to prevent the box from shaking or shifting during operation. The symmetrical limiting grooves 22 on both sides further enhance the fixing effect, making the box body evenly stressed and avoiding tilting or displacement caused by unilateral limiting. This ensures no risk of leakage during debris collection and allows the debris box 20 to be easily removed by simply pulling it out and squeezing the limiting block 25 again through the arc surface when emptying the waste. It balances the stability of the fixation with the convenience of operation, ensuring that the debris collection process is efficient and orderly.

[0026] Working Principle: When faced with residual crumbs and sticky residue on the surface of the dried jujube cake tray, the tray needs to be automatically cleaned after the drying process to prevent residue accumulation. This residue can cause charring and produce odors during subsequent drying, contaminating the new batch of jujube cake and affecting product flavor and hygiene. Opening the chamber door 3 and starting motor A7 drives the lead screw A8 to rotate, causing the grid plate 10 to slide smoothly out of the drying chamber 1. After placing the jujube cake to be dried on the surface of the grid plate 10, motor A7 is started in reverse, and the grid plate 10 returns to the drying chamber 1 along with the lead screw A8. The chamber door 3 is closed to form a sealed space. The heating rod 6 is turned on, and the generated heat is transferred to the jujube cake. The jujube cake inside the chamber can be observed through the transparent window 4. In the drying state, after drying is completed, turn off the heating rod 6, start the motor A7 to slide out the grid plate 10, take out the finished date cake, and after the grid plate 10 is reset, start the motor B12. The motor B12 drives the lead screw B13 to rotate, and the chip removal frame 15 moves smoothly with the cooperation of the slide bar B14 and slide bar block B16. The scraper 19 is in contact with the grid plate 10 to scoop up the blocky residue, and the brush 18 sweeps away the fine debris. The debris falls into the debris box 20. After cleaning, hold the handle 21 and pull gently. The debris box 20 squeezes the limiting block 25 to compress the spring 24. After taking out and emptying the debris, push it into the debris box 20 along the limiting groove 22. The limiting block 25 is reset and fixed under the action of the spring 24, completing one complete drying operation.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
