Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, and in particular to a flour drying device. Background Technology

[0002] Flour is a powdery substance made from wheat through grinding. Based on protein content, it can be divided into four main categories: high-gluten, medium-gluten, low-gluten, and gluten-free flour. Because flour is susceptible to mold growth due to moisture, manufacturers need to dry it during production to extend its shelf life and reduce quality and safety risks.

[0003] Sometimes flour may contain clumps that have become damp and condensed. However, many existing flour drying equipment only have agitators to tumble the whole batch of flour, and lack separate crushing equipment for the clumps. This results in the clumps having lower heat transfer efficiency and slower drying speed compared to other flour that has not clumped. Utility Model Content

[0004] This utility model proposes a flour drying device that solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A flour drying device includes a drying box, in which a grinding chamber and a hot drying chamber are sequentially arranged from top to bottom, and the grinding chamber and the hot drying chamber are connected to each other. A rotating shaft is rotatably arranged in the drying box, extending from the grinding chamber to the hot drying chamber. A motor for driving the rotating shaft is provided on the drying box. A sieve bucket is provided in the grinding chamber, and a grinding scraper is provided on the sieve bucket. The grinding scraper is fixedly arranged on the rotating shaft. A vibration mechanism for driving the sieve bucket to vibrate is provided in the drying box. A paddle is provided in the hot drying chamber, and the paddle is fixedly arranged on the rotating shaft.

[0007] The present invention is further configured such that: an annular limiting step is provided on the inner side wall of the grinding chamber, the annular plate is disposed above the limiting step, and the elastic abutment is abutted between the limiting step and the annular plate.

[0008] The present invention is further configured such that: a slider is provided on the outer side wall of the annular plate, and a limiting groove is provided on the inner side wall of the grinding cavity for the slider to slide up and down.

[0009] The present invention is further configured such that a through groove is provided on the side wall of the grinding scraper.

[0010] The present invention is further configured such that: an annular corrugated plate is provided between the annular plate and the limiting step, and the upper and lower ends of the corrugated plate are respectively sealed to the lower end surface of the annular plate and the upper end surface of the limiting step.

[0011] The present invention is further configured such that: the elastic support member is provided on the outer side of the corrugated plate; the upper end of the drying box is provided with a feed inlet; the feed inlet is connected to the grinding chamber; the upper side wall of the grinding chamber is provided with an annular enclosure; the lower end of the enclosure is provided with an inverted conical guide slope; the lower end of the guide slope converges toward the middle of the sieve hopper.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, this utility model discloses a flour drying device, including a drying chamber 1, as... Figure 1 As shown, the drying chamber 1 has a grinding chamber 11 and a hot drying chamber 12 arranged sequentially from top to bottom, wherein the grinding chamber 11 and the hot drying chamber 12 are connected to each other. A rotating shaft 22 is rotatably arranged in the drying chamber 1, which extends from the grinding chamber 11 to the hot drying chamber 12. The drying chamber 1 is equipped with a motor 21 for driving the rotating shaft 22 to rotate. In this structure, a sieve 31 is provided in the grinding chamber 11, and a number of sieve holes (not shown in the figure) are opened on the sieve 31. A grinding scraper 32 is provided on the sieve 31 and is fixedly arranged on the rotating shaft 22. At the same time, a vibration mechanism is provided in the drying chamber 1 for driving the sieve 31 to vibrate. In addition, a paddle 41 is provided in the hot drying chamber 12 and is fixedly arranged on the rotating shaft 22.

[0025] Furthermore, the vibration mechanism includes an annular plate 33 and an extension plate 34. The annular plate 33 is fixedly disposed on the upper outer edge of the sieve hopper 31, and the annular plate 33 is slidably connected to the inner wall of the grinding chamber 11. Specifically, a slider 52 is disposed on the outer wall of the annular plate 33, and a limiting groove 53 is provided on the inner wall of the grinding chamber 11 for the slider 52 to slide up and down. Meanwhile, the extension plate 34 is fixedly disposed on the rotating shaft 22 and extends from the rotating shaft 22 toward the annular plate 33. In this structure, the upper end face of the annular plate 33 is provided with a number of spherical grooves 35 along the circumferential direction. Correspondingly, the lower end face of the extension plate 34 is fixedly provided with spherical protrusions 36. Each spherical groove 35 is exactly on the rotation path of the spherical protrusions 36. In addition, an annular limiting step 51 is provided on the inner side wall of the grinding cavity 11. In this structure, the annular plate 33 is positioned above the limiting step 51, and an elastic abutment member 37 is provided between the limiting step 51 and the annular plate 33 to abut against each other.

[0026] The working principle of the above structure is as follows: Flour is first poured into the sieve hopper 31. After being poured into the sieve hopper 31, the rotating shaft 22 drives the grinding scraper 32 to start rotating. During the rotation of the grinding scraper 32, the spherical protrusions 36 enter and leave the spherical grooves 35 in sequence. During this process, the sieve hopper 31 will vibrate up and down, thereby accelerating the sieving of flour by the sieve hopper 31, so that the flour that has not clumped can move into the hot drying chamber 12. At the same time, for some clumps of flour, the grinding scraper 32 can break them up, so that they can also fall from the sieve hopper 31 into the hot drying chamber 12. After the flour falls into the hot drying chamber 12, the hot drying mechanism dries it. The paddle 41 is used to stir the flour to make it heat evenly. In this structure, the hot drying mechanism can refer to the prior art. Since it does not involve the key technical problems that this utility model is specifically trying to solve, it will not be described in detail here.

[0027] Furthermore, the elastic support member 37 is provided on the outer side of the corrugated plate 54. The upper end of the drying box 1 is provided with a feed inlet 13, which is connected to the grinding chamber 11. At the same time, the upper side wall of the grinding chamber 11 is provided with an annular wall 14. The lower end of the wall 14 is provided with an inverted conical guide ramp 15. The lower end of the guide ramp 15 converges towards the middle of the screen hopper 31, and the lower opening of the guide ramp 15 is smaller than the inner diameter of the annular plate 33. In addition, an annular corrugated plate 54 is provided between the annular plate 33 and the limiting step 51. The upper and lower ends of the corrugated plate 54 are respectively sealed to the lower end surface of the annular plate 33 and the upper end surface of the limiting step 51.

[0028] With this setup, when flour is poured into the grinding chamber 11, it is collected into the sieve hopper 31 by the influence of the guide slope 15. At the same time, when flour falls from the sieve hopper 31, the corrugated plate 54 can act as a shield to prevent flour from accumulating on the limiting step 51. The corrugated plate 54 slides and contracts with the up and down sliding of the annular plate 33, which can shake off the flour on the corrugated plate 54.

[0029] Furthermore, a passage groove 321 is provided on the side wall of the grinding scraper 32. This structure is used to reduce the resistance received by the grinding scraper 32 when it rotates. When some flour cannot be sieved out by the sieve hopper 31 in time, it can pass through the passage groove 321 first.

[0030] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.
