Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grain processing technology, and in particular relates to a rice cooling and moistening device. Background Technology
[0002] Rice is an indispensable food. During the processing of rice, it needs to go through many processes such as cleaning, hulling, separating the grains from the husk, thickness selection, moistening, milling by rice milling machine, and white rice sieving. The multiple milling processes generate heat, and the temperature of the rice rises sharply after hulling, reaching about 41℃-52℃. If it is overheated, it will cause nutrient loss and make it more susceptible to damage from pests and mold. If the high-temperature rice grains are directly processed in subsequent processes, it will not only increase the difficulty of subsequent processing, but also reduce the whole rice rate and increase the broken rice rate, because the high-temperature rice grains are easy to break. Furthermore, subsequent processing will raise the temperature of the rice grains, causing the rice quality to decline and making it less resistant to storage. Therefore, it is necessary to cool the rice.
[0003] In existing technologies, rice cooling equipment is commonly used to cool and lower the temperature of rice. However, existing rice cooling equipment has a single water inlet direction, resulting in uneven cooling of the rice. Furthermore, the rice has a short travel distance within the rice cooling equipment, leading to insufficient cooling. Utility Model Content
[0004] In view of this, in order to solve the problem of uneven and insufficient cooling of rice by the cooling water pipes of existing rice cooling equipment, this utility model proposes a rice cooling and moisturizing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rice cooling and moistening device includes: multiple water-cooled layers connected in sequence along a vertical direction; each water-cooled layer includes a shell and multiple cooling water pipe groups, which are spaced apart along a vertical direction, and each cooling water pipe group includes multiple cooling water pipes, which are spaced apart along a horizontal direction; the water inlet directions of every two adjacent rows of cooling water pipe groups are opposite.
[0007] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the multiple cooling water pipes of each pair of adjacent cooling water pipe groups are arranged in an alternating manner; or the multiple cooling water pipes of each pair of adjacent cooling water pipe groups are arranged correspondingly.
[0008] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the cross-section of the cooling water pipe is elliptical, circular, triangular, or rhomboid.
[0009] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the height of the elliptical cross-section of the cooling water pipe is greater than its width.
[0010] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the height of the elliptical cross-section of the cooling water pipe is 30-50cm; the width of the elliptical cross-section of the cooling water pipe is 20-30cm.
[0011] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the distance between two adjacent cooling water pipes in the same cooling water pipe group is 1-20cm.
[0012] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the cooling water temperature at the inlet end of the cooling water pipe is lower than the cooling water temperature at the outlet end.
[0013] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the cooling water pipe extends in a horizontal direction.
[0014] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the number of water-cooled layers is 6, and the number of cooling water pipe groups in each water-cooled layer is 6.
[0015] As a preferred embodiment of the above-mentioned rice cooling and moistening device, the rice cooling and moistening device further includes a grain discharge facility, which includes a grain discharge roller and an R-groove. The grain discharge roller is rotatably arranged and can discharge rice from the water-cooled stratification to the R-groove. The gap between the grain discharge roller and the R-groove is 1-20cm.

[0017] 1. This utility model provides a rice cooling and moistening device. The device comprises multiple vertically distributed water-cooling layers, each containing multiple vertically distributed cooling water pipe arrays. Each cooling water pipe array includes multiple cooling water pipes. As rice falls from top to bottom, it passes through these multiple cooling water pipe arrays in sequence, resulting in more thorough cooling. The water inlet directions of any two adjacent rows of cooling water pipe arrays are opposite, meaning that water is introduced in a crisscross manner between adjacent rows. For example, water enters from the left side of the first row, the right side of the second row, the left side of the third row, and so on. Because the water temperature differs between the inlet and outlet ends of the cooling water pipes, this crisscross water inlet method ensures more uniform cooling of the rice.

Cold water enters the cooling water pipe, and hot water flows out of the cooling water pipe.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.
[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0041] See Figure 1-8 This invention provides a rice cooling and moistening device, which includes multiple water-cooled layers 1 connected sequentially in a vertical direction. Each water-cooled layer 1 includes a shell 11 and multiple cooling water pipe groups, which are spaced apart in a vertical direction. Each cooling water pipe group includes multiple cooling water pipes 12, which are spaced apart in a horizontal direction. The water inlet directions of every two adjacent rows of cooling water pipe groups are opposite.
[0042] In this embodiment, there are 6 water-cooled strata 1, and each water-cooled strata 1 has 6 cooling water pipe assemblies. There are a total of 36 cooling water pipe assemblies.
[0043] In this rice cooling and moistening device, multiple water-cooling layers 1 are distributed vertically. Within each water-cooling layer 1, multiple cooling water pipe groups are distributed vertically. Each cooling water pipe group includes multiple cooling water pipes 12. As rice falls from top to bottom, it passes through these multiple cooling water pipe groups in sequence, ensuring more thorough cooling. The water inlet directions of any two adjacent rows of cooling water pipe groups are opposite; that is, water enters in a crisscross pattern between adjacent rows. For example, water enters from the left side of the first row, the right side of the second row, the left side of the third row, and so on. Because the water temperature at the inlet and outlet of the cooling water pipes 12 is different, this crisscross water inlet method ensures more uniform cooling of the rice.
[0044] In other embodiments, each pair of adjacent cooling water pipes 12 in the same row of cooling water pipes may have different water inlet directions, i.e., cross-inlet water, so as to make the rice cool more evenly.
[0045] Optionally, the multiple cooling water pipes 12 in every two adjacent rows of cooling water pipe groups are staggered; or the multiple cooling water pipes 12 in every two adjacent rows of cooling water pipe groups are correspondingly arranged. It is understood that, as Figure 5 As shown, the multiple cooling water pipes 12 of two adjacent rows of cooling water pipe groups are staggered, meaning that the multiple cooling water pipes 12 of the upper row of cooling water pipe groups are spaced apart, and the multiple cooling water pipes 12 of the lower row correspond to the gaps between two cooling water pipes 12 of the upper row. Figure 4 As shown, the multiple cooling water pipes 12 in two adjacent rows of cooling water pipe groups are arranged in a vertically spaced manner, which makes the cooling of rice more uniform.
[0046] Optionally, the cross-section of the cooling water pipe 12 is elliptical, circular, triangular, or rhomboid.
[0047] It is understandable that when the cross-section of the cooling water pipe 12 is triangular, the tip points upwards; when the cross-section of the cooling water pipe 12 is rhomboid, the tip with an acute angle points upwards.
[0048] It is understood that the cross-section of the cooling water pipe 12 is elliptical, that is, the cross-section of the cooling water pipe 12 is oval. Optionally, the height of the elliptical cross-section of the cooling water pipe 12 is greater than its width. Optionally, the height Y of the elliptical cross-section of the cooling water pipe 12 is 30-50cm; the width X of the elliptical cross-section of the cooling water pipe 12 is 20-30cm. For example, the height Y and width X of the elliptical cross-section of the cooling water pipe 12 are 30cm and 23cm respectively; or, the height Y and width X of the elliptical cross-section of the cooling water pipe 12 are 50cm and 30cm respectively.
[0049] Optionally, the distance between two adjacent cooling water pipes 12 in the same cooling water pipe group is 1-20cm. The spacing between two cooling water pipes 12 can be 10cm, 15cm or 20cm.
[0050] Optionally, the cooling water temperature at the inlet of the cooling water pipe 12 is lower than the cooling water temperature at the outlet. Cold water enters the cooling water pipe 12, and hot water flows out of the cooling water pipe 12.
[0051] Optionally, the cooling water pipe 12 extends in a horizontal direction.
[0052] Optionally, the rice cooling and moistening device also includes a discharge mechanism, which includes a discharge roller 21 and an R-groove 22. The discharge roller 21 is rotatable and discharges rice from the water-cooled layer 1 to the R-groove 22. The gap between the discharge roller 21 and the R-groove 22 is 1-20 cm. It is understood that the R-groove 22 is inclined, and the rice in the water-cooled layer 1 moves towards the discharge roller 21 through a guide structure. The rotation of the discharge roller 21 causes the rice to fall into the R-groove 22. The 1-20 cm gap between the discharge roller 21 and the R-groove 22 allows the rice to fall smoothly.
[0053] Obviously, the above-disclosed embodiments of the present invention are merely for illustrating the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to only the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. It is neither necessary nor possible to exhaustively list all embodiments here.
