Description

Technical Field

[0001] This utility model relates to the technical field of glutinous rice flour processing equipment, specifically to a glutinous rice flour sample drying device. Background Technology

[0002] Glutinous rice flour, a common food ingredient, is widely used in the food processing industry. During production, to ensure that the quality and performance of glutinous rice flour meet standards, a series of analyses and tests are typically performed. These tests include particle size analysis, mechanical property testing, chemical property testing, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) analysis, and water absorption testing. To ensure the accuracy and reliability of the test results, glutinous rice flour samples need to undergo drying pretreatment before testing. The main purposes of drying pretreatment are to remove moisture from the sample, standardize testing conditions, prevent microbial interference, facilitate subsequent processing, and extend the sample's shelf life.

[0003] Existing drying oven (refer to the attached instruction manual) Figure 7 The method involves placing a glutinous rice flour sample in a container within a drying oven, then heating it using an electric heating plate mounted on the top wall of the oven. However, in practical use, the following drawbacks exist: During the heating process, heat is primarily transferred from the top to the bottom of the glutinous rice flour sample, resulting in uneven heating and poor drying. This uneven drying affects the overall quality of the sample, impacting the accuracy of subsequent testing results and potentially leading to microbial residue, further affecting the accuracy of the results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a glutinous rice flour sample drying device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A glutinous rice flour sample drying device is provided, including a drying box with an opening on one side, a vertical partition installed inside the drying box to divide its inner cavity into a drying chamber and an installation chamber, an installation block installed on the inner top wall of the drying chamber, an installation groove provided at the bottom of the installation block, and an electric heating plate installed on the inner top wall of the installation groove.

[0007] Below the mounting block is a receiving box, which is connected to a lifting assembly for driving it up and down. When the receiving box moves up to its limit position, the receiving groove at its top and the mounting groove are attached to each other and enclosed to form a closed drying space.

[0008] A rotating shaft extending into the mounting groove is rotatably mounted on the vertical partition. Two scrapers for driving the material at the bottom of the drying space upward are symmetrically mounted on the outer wall of the rotating shaft. An electric motor connected to the rotating shaft is installed in the mounting cavity.

[0009] Furthermore, the lifting assembly includes a telescopic rod, a support plate, and an adjusting component;

[0010] Two vertical telescopic rods are symmetrically installed on the inner bottom wall of the drying chamber. The tops of the two telescopic rods are connected to a tray installed on the bottom of the receiving box. An adjusting component connected to the tray is installed inside the drying chamber. The adjusting component is used to move the tray up and down along the extension direction of the two telescopic rods.

[0011] Furthermore, the adjusting component includes a slider, a hinge rod, and an adjusting rod;

[0012] The slider is slidably mounted on the inner bottom wall of the drying chamber, and its sliding direction is perpendicular to the opening end of the drying box. The slider is sleeved on the adjusting rod and threadedly connected to it.

[0013] The support plate and the slider are respectively hinged to the top and bottom ends of the hinge rod;

[0014] One end of the adjusting rod is rotatably mounted on the inner bottom wall of the drying chamber, and its extension direction is parallel to the sliding direction of the slider.

[0015] Furthermore, a sealing plate for sealing the installation cavity is fixedly installed on the drying oven by screws, and a control panel is fixedly installed on the sealing plate. The control panel is electrically connected to the electric heating plate and the motor respectively.

[0016] Furthermore, a limiting plate is installed at the bottom of the mounting block, and a T-shaped through groove is provided at the bottom of the limiting plate. A limiting block corresponding to the through groove is installed on the receiving box. When the top of the receiving box is attached to the bottom of the mounting block to form a drying space, the limiting block is located in the through groove, and the vertical wall of the limiting block is attached to the vertical wall of the through groove.

[0017] Furthermore, the drying oven is hinged with a door for sealing the opening of the drying chamber, and a positioning element is installed on the drying oven to maintain the closed state of the drying chamber with the door closed.

[0018] Furthermore, the positioning element includes magnet one and magnet two;

[0019] The drying oven has a groove 1, in which a magnet 1 is fixedly installed. The oven door has a groove 2, in which a magnet 2 is fixedly installed. When the oven door closes the drying chamber, magnet 1 and magnet 2 stick together and attract each other.

[0020] Furthermore, the rotating shaft is also equipped with multiple stirring rods perpendicular to it.

[0021] This invention provides a device for drying glutinous rice flour samples. Compared with the prior art, it has the following advantages:

[0022] 1. When drying glutinous rice flour, the glutinous rice flour in the receiving tank is turned over, which is beneficial to the overall drying of the glutinous rice flour in the receiving tank. This replaces the method of drying the glutinous rice flour in the receiving tank from top to bottom, improves the drying uniformity of the glutinous rice flour in the receiving tank, and thus improves the accuracy of the test results of the glutinous rice flour in the later stage.

[0034] Example 1

[0035] To address the technical problems in the background section, the following glutinous rice flour sample drying device is provided:

[0036] Combination Figures 1-6 As shown, the present invention provides a glutinous rice flour sample drying device, including a drying box 1 with one side open. A vertical partition 11 perpendicular to the opening end is fixedly installed inside the drying box 1, dividing the interior of the drying box 1 into an independent drying chamber 12 and an installation chamber 13. An installation block 2 is fixedly installed on the inner top wall of the drying chamber 12, and an installation groove 21 is opened at the bottom of the installation block 2. An electric heating plate 22 is fixedly installed on the inner top wall of the installation groove 21. It is worth noting that the electric heating plate 22 is provided with an electric heating wire. When in use, the electric heating plate 22 is energized, and the electric heating wire in the electric heating plate 22 is energized to convert electrical energy into heat energy, so that heat energy can be dissipated into the installation groove 21 through the electric heating plate 22. It is worth noting that an inclined exhaust pipe 23 is connected through the side wall of the installation block 2 away from the drying chamber 12. The exhaust pipe 23 is inclined downward along the interior of the installation groove 21, and the highest end of the exhaust pipe 23 extends through the drying box 1 to the outside of the drying box 1.

[0037] A rotating shaft 3 extending into the mounting groove 21 is rotatably mounted on the vertical partition 11. Scrapers 31 are symmetrically fixedly mounted on the outer wall of the rotating shaft 3 and within the mounting groove 21. Stirring rods 32 are fixedly connected in a horizontal linear array on both sides of the outer wall of the rotating shaft 3 and within the mounting cavity 13. An electric motor 33 for driving the rotating shaft 3 to rotate is fixedly mounted on the vertical partition 11 and within the mounting cavity 13.

[0038] The inner bottom wall of the drying chamber 12 is equipped with a lifting assembly 4. A container 5 for holding glutinous rice flour is placed on the top of the lifting assembly 4. A receiving groove 51 is opened on the top of the container 5. The lifting assembly 4 is used to lift the container 5 so that the top of the container 5 is in contact with the bottom of the mounting block 2. When the top of the container 5 is in contact with the mounting block 2, the scraper 31 and the stirring rod 32 extend into the receiving groove 51 and are in contact with the cross section of the inner wall of the receiving groove 51. It is worth noting that when the top of the container 5 is in contact with the bottom of the mounting block 2, the container 5 seals the bottom opening of the mounting groove 21, and the receiving groove 51 is connected to the inside of the mounting groove 21. The center of the longitudinal section of the receiving groove 51 is located in the axial direction of the rotating shaft 3. This equipment is powered by an external power source.

[0039] When drying glutinous rice flour, the flour to be dried is poured into the receiving groove 51 of the receiving box 5. The receiving box 5 is then placed on the lifting assembly 4, which lifts it so that the top of the receiving box 5 is in contact with the bottom of the mounting block 2. At this time, the scraper 31 and stirring rods 32 extend into the receiving groove 51. The electric heating plate 22 is turned on, dissipating heat into the mounting groove 21, raising the internal temperature of the mounting groove 21, and thus raising the internal temperature of the receiving groove 51. This achieves the drying effect of the glutinous rice flour in the receiving groove 51. During this process, the motor 33 is turned on, driving the rotating shaft 3 to rotate on the vertical partition 11. This, in turn, causes the scraper 31 and multiple stirring rods 32 to rotate around the rotating shaft 3. During the process, the glutinous rice flour in the receiving tank 51 is scraped to place it on the scraper 31. When the scraper 31 rotates around the rotating shaft 3 and tilts downward along the direction of the rotating shaft 3, the glutinous rice flour on the scraper 31 slides down the surface of the scraper 31 and falls into the receiving tank 51. During this process, when the glutinous rice flour slides down the surface of the scraper 31 and comes into contact with the stirring rod 32, it slides to both sides of the stirring rod 32, thus achieving the effect of dispersing the glutinous rice flour. Therefore, when the scraper 31 and multiple stirring rods 32 rotate around the rotating shaft 3, the glutinous rice flour in the receiving tank 51 can be turned over, which is beneficial to the overall drying of the glutinous rice flour in the receiving tank 51. This replaces the method of drying the glutinous rice flour in the receiving tank 51 from top to bottom, improves the drying uniformity of the glutinous rice flour in the receiving tank 51, and thus improves the accuracy of the test results of the glutinous rice flour in the later stage.

[0040] Example 2

[0041] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0042] In this embodiment, the lifting assembly 4 includes a telescopic rod 41, a support plate 42, and an adjusting component 43;

[0043] The inner bottom wall of the drying chamber 12 is symmetrically fixedly equipped with vertical telescopic rods 41, and the top of the two telescopic rods 41 is fixedly equipped with a support plate 42. An adjusting component 43 connected to the support plate 42 is installed in the drying chamber 12. It is used to make the support plate 42 slide along the two telescopic rods 41 or stop sliding. In use, the support plate 42 can be made to slide up or down along the two telescopic rods 41 by adjusting the component 43, so as to realize the lifting effect of the container 5 placed on the support plate 42.

[0044] In this embodiment, the adjusting member 43 includes a slider 431, a hinge rod 432, and an adjusting rod 433;

[0045] A slider 431 is slidably installed on the inner bottom wall of the drying chamber 12 along the opening end of the drying box 1. The top of the slider 431 is hinged to a hinge rod 432 that is hinged to the bottom of the support plate 42. A horizontal adjusting rod 433 is rotatably installed on the inner bottom wall of the drying chamber 12. The adjusting rod 433 is threadedly connected to the slider 431. In use, a rotational force is applied to the adjusting rod 433, which allows the slider 431 to slide on the inner bottom wall of the drying box 1. The hinge rod 432 rotates around itself hinged on the slider 431. The other end of the hinge rod 432 rotates with the support plate 42, which allows the support plate 42 to slide up or down along the two telescopic rods 41. The operation is simple.

[0046] In this embodiment, a sealing plate 14 for sealing the installation cavity 13 is fixedly installed on the drying oven 1 by screws. A control panel 15 is fixedly installed on the sealing plate 14. The control panel 15 is electrically connected to the electric heating plate 22 and the motor 33. In use, it is convenient to control the electric heating plate 22 and the motor 33 on and off.

[0047] Example 3

[0048] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0049] In this embodiment, a limiting plate 6 is fixedly installed on the bottom of the mounting block 2, on the side of the mounting groove 21 away from the opening of the drying oven 1. The limiting plate 6 has a T-shaped through groove 61, and the bottom of the through groove 61 penetrates the bottom of the limiting plate 6. A limiting block 52 with a T-shaped cross-section is fixedly installed on one side of the receiving box 5. When the top of the receiving box 5 is in contact with the bottom of the mounting block 2, the limiting block 52 is inserted into the through groove 61 and engages with the limiting plate 6. By setting the limiting plate 6 and the limiting block 52, when the receiving box 5 is placed on the tray 42, the limiting block 52 is located directly below the through groove 61, and the tray 42 slides upward along the two telescopic rods 41. When the top of the receiving box 5 is in contact with the bottom of the mounting block 2, the limiting block 52 is inserted into the through groove 61 and engages with the limiting plate 6. Thus, the limiting plate 6 and the limiting block 52 can be used to limit the receiving box 5.

[0050] In this embodiment, the drying oven 1 is hinged with a door 16 for sealing the opening of the drying chamber 12. By setting the door 16, the opening of the drying chamber 12 is sealed, making the equipment more reasonable. The drying oven 1 is equipped with a positioning component 7 connected to the door 16, which is used to position or cancel the positioning between the drying oven 1 and the door 16. By setting the positioning component 7, the positioning effect between the drying oven 1 and the door 16 is achieved.

[0051] In this embodiment, the positioning element 7 includes a first magnet 71 and a second magnet 72;

[0052] The drying oven 1 has a groove 1 near its opening end, located above and below the drying chamber 12. A magnet 71 is fixedly installed on the drying oven 1 within the groove 1. The top and bottom of the door 16 have two grooves, and a magnet 72 is fixedly installed on the door 16 within the groove 2. When the door 16 blocks the opening end of the drying chamber 12, the two magnets 72 are magnetically attracted to the two magnets 71 respectively. In use, when the door 16 blocks the opening end of the drying chamber 12, the two magnets 72 are magnetically attracted to the two magnets 71 respectively, thus positioning the door 16 relative to the drying oven 1. Conversely, when a rotational force is applied to the door 16, causing it to rotate on the drying oven 1, the two magnets 72 are separated from the two magnets 71 respectively, thus canceling the positioning effect of the door 16 relative to the drying oven 1.
