Description

Technical Field

[0001] This application relates to the field of rice cooling technology, and in particular to a cooling silo for rice production. Background Technology

[0002] Polishing and color sorting are two crucial steps in rice processing. To ensure the efficiency of these steps, the rice needs to undergo proper cooling. Cooling not only stabilizes the rice temperature, preventing quality degradation caused by high temperatures, but also improves the effectiveness of subsequent polishing and color sorting.

[0003] However, in existing rice cooling silos, rice is typically transported directly into the silo via an elevator. While fans are used to cool the rice, uneven contact between the rice and the cold air results in some rice not receiving sufficient heat dissipation. Specifically, when rice accumulates inside the cooling silo, those that haven't cooled properly tend to pile up, waiting for natural cooling, which prolongs the cooling time and may even negatively impact rice quality due to localized overheating.

[0004] To address the aforementioned issues, a cooling chamber for rice production is now being designed. Utility Model Content

[0005] This application provides a cooling chamber for rice production to solve the problem in related technologies where rice does not get enough heat due to uneven contact between the rice and the cold air blown by the fan during use.

[0006] Firstly, a cooling chamber for rice production is provided, comprising:

[0007] The storage chamber has an internal cavity for cooling rice; an exhaust cage is embedded inside the storage chamber.

[0008] The silo body has two sets of partition plates arranged opposite each other, and the partition plates have ventilation holes. The partition plates and the exhaust cage divide the silo body into multiple cooling chambers for the flow of rice. The cooling chamber has two sets of guide plates arranged opposite each other, with adjacent sets of guide plates arranged vertically and horizontally to guide the flow of rice in the cooling chamber from top to bottom.

[0009] A gas supply mechanism includes branch pipes distributed along the height of the chamber, with multiple interfaces provided on the inner side of each branch pipe. The interfaces communicate with the cooling chamber and are used to supply gas to the interior of the cooling chamber. A main pipe is provided on the chamber and is used to supply gas to the multiple branch pipes.

[0010] The exhaust cage extends to the outside of the chamber at both ends and is used to exhaust the gas inside the exhaust cage.

[0011] In some embodiments, the exhaust cage is rectangular with an open top and equidistant exhaust holes. Gas that exchanges heat with the rice enters the exhaust cage through the exhaust holes on both sides and is then discharged to the outside of the storage chamber through the exhaust holes at both ends.

[0012] A guide block is provided at the top of the exhaust cage. The guide block is conical to prevent rice from piling up at the top of the exhaust cage.

[0013] In some embodiments, the partition plate includes a horizontal plate disposed inside the silo body, and a plurality of vertical plates are embedded along the length of the horizontal plate. The horizontal plate and the vertical plates are arranged perpendicularly, and the two ends of the vertical plates are respectively connected to the inner wall of the silo body and the exhaust cage.

[0014] Both the horizontal and vertical plates have equidistant ventilation holes.

[0015] In some embodiments, the branch pipe is rectangular and adapted to the surface of the container body, and multiple interfaces are distributed at equal intervals on the inner side of the corresponding branch pipe;

[0016] The main pipeline includes an interconnected air supply channel and an air vent housing. The air vent housing has a cavity inside and is embedded between multiple branch pipes. All of the multiple branch pipes are connected to the cavity of the air vent housing. One end of the air supply channel is connected to an external fan, and the other end is connected to the cavity of the air vent housing.

[0017] In some embodiments, the hopper body is provided with a top cover, and the top cover and the hopper body enclose a feeding cavity, which is located above the cooling cavity and is interconnected with it;

[0018] The top cover is provided with a feeding pipe, and a feeding hopper is provided on one side of the feeding pipe.

[0019] In some embodiments, a material distribution mechanism is also included, which includes a drive motor disposed above the feeding pipe, a rotating shaft disposed inside the feeding chamber, a material distribution plate connected to one end of the rotating shaft, the material distribution plate having multiple discharge holes, and the other end of the rotating shaft being connected to the output shaft of the drive motor.

[0020] The drive motor is used to drive the distribution plate to rotate, and the rice on the distribution plate falls into multiple cooling chambers through the discharge hole and the edge of the distribution plate.

[0021] In some embodiments, the guide plate has vent holes that are evenly distributed.

[0022] In some embodiments, both ends of the exhaust cage extending outward are provided with extraction chambers, and the extraction chambers are provided with extraction pipes that communicate with an external fan.

[0023] In some embodiments, the bottom of the silo is provided with a plurality of rectangularly distributed discharge hoppers, the discharge hoppers being conical in shape and having valves at their bottoms.

[0024] This application provides a cooling chamber for rice production. The chamber is divided into multiple cooling chambers by partitions and an exhaust cage, allowing the rice to be distributed more evenly within each chamber and improving cooling efficiency. The staggered arrangement of the guide plates increases the contact area and time between the rice and the gas, further enhancing the cooling effect.

[0025] The pipes and interfaces allow gas to enter each cooling chamber evenly, preventing local overheating or overcooling. At the same time, the exhaust holes of the exhaust cage ensure that the gas can be discharged smoothly, maintaining the gas flow in the cooling chamber.

[0026] The guide plate not only increases the flowability of the rice, but also reduces the accumulation and blockage of rice during the cooling process, making the cooling process smoother. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] This application provides a cooling chamber for rice production, which solves the problem in related technologies where rice does not get enough heat due to uneven contact between the rice and the cold air blown by the fan during use.

[0037] Please see Figures 1-3 A cooling chamber for rice production includes: a chamber body 1, which has a cavity for cooling rice; an exhaust cage 2 embedded inside the chamber body 1; two sets of partition plates 3 arranged opposite each other inside the chamber body 1, the partition plates 3 having ventilation holes, the partition plates 3 and the exhaust cage 2 dividing the cavity of the chamber body 1 to form multiple cooling chambers 4 for rice flow; two sets of guide plates 5 arranged opposite each other inside the cooling chambers 4, the adjacent sets of guide plates 5 being arranged vertically and crosswise, guiding the flow of rice in the cooling chambers 4 from top to bottom; a gas supply mechanism 6, which includes branch pipes 61 distributed along the height of the chamber body 1, the inner side of the branch pipes 61 having multiple interfaces 62, the interfaces 62 communicating with the cooling chambers 4 and used to supply gas into the cooling chambers 4; a main pipe 63 disposed on the chamber body 1, the main pipe 63 being used to supply gas to the multiple branch pipes 61; and the exhaust cage 2 extending to the outside of the chamber body 1 at both ends and used to discharge the gas inside the exhaust cage 2.

[0038] Rice is fed into the chamber inside the silo 1 by an external elevator. The exhaust cage 2 embedded inside the silo 1 and the two sets of partition plates 3 arranged opposite each other divide the chamber into multiple cooling chambers 4. The ventilation holes on the partition plates 3 allow gas to flow between the cooling chambers 4.

[0039] When the gas supply mechanism 6 is activated, the main pipe 63 supplies gas, such as cold air or cold wind, to the branch pipes 61 distributed along the height of the silo body 1. Multiple interfaces 62 on the inner side of the branch pipes 61 are connected to the cooling chambers 4, so that the gas is evenly delivered into each cooling chamber 4. The gas exchanges heat with the rice in the cooling chamber 4, removing heat from the surface of the rice.

[0040] Inside the cooling chamber 4, two sets of guide plates 5 are arranged in a staggered pattern to guide the flow of rice from top to bottom. This flow pattern increases the contact area and time between the rice and the gas, thereby improving the cooling efficiency.

[0041] After heat exchange with the rice, the gas enters the interior of the exhaust cage 2 through the exhaust holes, and then exits through the portions extending from both ends of the exhaust cage 2 to the outside of the storage chamber 1. The exhaust cage 2 ensures that the gas can be discharged smoothly, avoiding gas accumulation and overheating.

[0042] The chamber is divided into multiple cooling chambers 4 by the partition plate 3 and the exhaust cage 2, allowing the rice to be distributed more evenly within the cooling chambers and improving cooling efficiency. The vertically arranged guide plates 5 increase the contact area and time between the rice and the gas, further enhancing the cooling effect.

[0043] The gas can be evenly introduced into each cooling chamber 4 through the branch pipe 61 and the interface 62, avoiding local overheating or overcooling. At the same time, the exhaust port of the exhaust cage 2 ensures that the gas can be smoothly discharged, maintaining the gas flow in the cooling chamber.

[0044] The guide plate 5 not only increases the flowability of the rice, but also reduces the accumulation and blockage of rice during the cooling process, making the cooling process smoother.

[0045] In summary, through the rational use of the exhaust cage 2, the partition plate 3, the cooling chamber, the guide plate 5, and the air supply mechanism 6, an efficient, uniform, and smooth cooling process is achieved, thereby improving the cooling quality and production efficiency of rice.

[0046] like Figure 2 and Figure 5 As shown, the exhaust cage 2 in this embodiment is rectangular with an open top, and has equally spaced exhaust holes. The gas that exchanges heat with the rice enters the exhaust cage 2 through the exhaust holes on both sides and is then discharged to the outside of the storage body 1 through the exhaust holes at both ends. A guide block 21 is provided on the top of the exhaust cage 2. The guide block 21 is conical to prevent rice from accumulating on the top of the exhaust cage.

[0047] The chamber inside the compartment 1 is divided into multiple cooling chambers 4 by the exhaust cage 2 and the partition plate 3. The vent holes on the partition plate 3 allow gas to flow between the cooling chambers 4.

[0048] Gas, such as cold air, is supplied to the branch pipe 61 through the main pipe 63. The interface 62 on the inner side of the branch pipe 61 sends the gas into the cooling chamber 4 to exchange heat with the rice. The gas after exchanging heat with the rice enters the interior of the exhaust cage 2 through the equally spaced exhaust holes on both sides. The gas entering the exhaust cage 2 flows inside and is discharged to the outside of the silo 1 through the exhaust holes at both ends of the exhaust cage.

[0049] The exhaust cage 2 allows the gas that has exchanged heat with the rice to enter and exit smoothly, achieving efficient heat dissipation and improving cooling efficiency.

[0050] like Figure 2 As shown, specifically, in this embodiment, the partition plate 3 includes a horizontal plate 31 disposed inside the hopper 1, and a plurality of vertical plates 32 are embedded along the length of the horizontal plate 31. The horizontal plate 31 and the vertical plates 32 are arranged perpendicularly, and the two ends of the vertical plates 32 are respectively connected to the inner wall of the hopper 1 and the exhaust cage 2; both the horizontal plate 31 and the vertical plates 32 are provided with equidistant ventilation holes.

[0051] The internal chamber of the compartment 1 is divided into multiple cooling chambers 4 by the partition plate 3 and the exhaust cage 2. The partition plate 3 is composed of horizontal plate 31 and vertical plate 32, forming a grid structure.

[0052] The horizontal plate 31 and vertical plate 32 of the partition plate 3 are arranged vertically to form a grid structure, which allows the gas to flow smoothly between the cooling chambers 4 and improves the heat dissipation efficiency.

[0053] The equidistant vents ensure uniform gas distribution on the partition plate 3, avoiding local overheating or overcooling.

[0054] like Figure 3 As shown, in one embodiment, the branch pipe 61 is rectangular and adapted to the surface of the chamber 1, and multiple interfaces 62 are equidistantly distributed on the inner side of the corresponding branch pipe 61; the main pipe 63 includes an interconnected air supply channel 631 and a ventilated shell 632, the ventilated shell 632 has a cavity inside, the ventilated shell 632 is embedded between multiple branch pipes 61, and multiple branch pipes 61 are all connected to the cavity of the ventilated shell 632, one end of the air supply channel 631 is connected to an external fan, and the other end is connected to the cavity of the ventilated shell 632.

[0055] When the external fan is started, cold air is sent into the air supply channel 631. The gas in the air supply channel 631 enters the cavity of the ventilation shell 632. The ventilation shell 632 is embedded between multiple branch pipes 61 to ensure that the gas can be evenly distributed to each branch pipe 61.

[0056] The interface 62 on the inner side of each branch pipe 61 sends gas into the corresponding cooling chamber 4. Since the branch pipe 61 is rectangular and adapts to the surface of the chamber 1, it can ensure the uniform distribution of gas within the chamber 1. The gas entering the cooling chamber 4 exchanges heat with the rice, carrying away the heat from the rice and achieving a cooling effect.

[0057] After heat exchange, the gas is discharged to the outside of the chamber 1 through the vent holes on the partition plate 3 and the exhaust holes of the exhaust cage 2, completing the entire cooling cycle.

[0058] The branch pipe 61 is rectangular and fits the surface of the chamber 1, ensuring uniform gas distribution within the chamber 1. Multiple ports 62 are evenly distributed inside the branch pipe 61, further enhancing gas uniformity. The cavity structure of the vent housing 632 allows gas to smoothly enter the branch pipe 61 from the gas supply channel 631, preventing gas accumulation and blockage within the pipe.

[0059] like Figure 1 and Figure 4 As shown, in one embodiment, the silo body 1 is provided with a top cover 7, and the top cover 7 and the silo body 1 enclose a feeding cavity 71, which is located above the cooling cavity 4 and is interconnected with it; the top cover 7 is provided with a feeding pipe 8, and a feeding hopper 81 is provided on one side of the feeding pipe 8.

[0060] Rice enters the feeding pipe 8 through the feeding hopper 81 and then falls into the feeding chamber 71. The feeding chamber 71 is located above and connected to the cooling chamber 4. The rice falls naturally from the feeding chamber 71 into the cooling chamber 4 below, where the cooling process begins.

[0061] like Figure 4 As shown, in a preferred embodiment, it also includes a material distribution mechanism 9, which includes a drive motor 91 disposed above the feeding pipe 8, a rotating shaft 92 disposed inside the feeding chamber 71, and a material distribution plate 93 connected to one end of the rotating shaft 92. The material distribution plate 93 has multiple discharge holes, and the other end of the rotating shaft 92 is connected to the output shaft of the drive motor 91. The drive motor 91 is used to drive the material distribution plate 93 to rotate, and the rice on the material distribution plate 93 falls into multiple cooling chambers 4 through the discharge holes and the edge of the material distribution plate 93.

[0062] Rice is fed into the feeding hopper 81 by an elevator, and then enters the feeding chamber 71 through the feeding pipe 8.

[0063] Above the feeding chamber 71, the distributing mechanism 9 begins to operate. The drive motor 91 drives the rotating shaft 92 to rotate, which in turn drives the distributing disc 93 to rotate. The distributing disc 93 has multiple discharge holes. When rice falls onto the distributing disc 93, as the distributing disc rotates, the rice is evenly distributed into each discharge hole and falls down. At the same time, the rice falls from the edge of the distributing disc 93 and falls into the multiple cooling chambers 4 below.

[0064] The distribution mechanism 9 ensures that the rice is evenly distributed into multiple cooling chambers 4, avoiding the accumulation and overheating of rice in a single cooling chamber and improving the uniformity and efficiency of cooling.

[0065] Through the rotation of the distribution plate 93 and the discharge hole, the rice can fall into the cooling chamber 4 quickly and evenly to start the cooling process, thereby improving the cooling efficiency.

[0066] like Figure 4 As shown, specifically, the guide plate 5 described in this embodiment has equidistantly distributed exhaust holes.

[0067] The exhaust vents are evenly distributed on the guide plate 5, ensuring that the cooling medium can pass through the cooling chamber 4 evenly and smoothly, and fully exchange heat with the rice.

[0068] Guided by the guide plate 5, the rice flows evenly from top to bottom, fully exchanging heat with the cooling medium to ensure uniform cooling of the rice.

[0069] like Figure 5 and Figure 6 As shown, preferably, both ends of the exhaust cage 2 extending outward are provided with an exhaust chamber 10, and the exhaust chamber 10 is provided with an exhaust pipe that communicates with an external fan.

[0070] An external fan extracts the heat-exchanged gas from the exhaust cage 2 through an exhaust pipe and discharges it to the outside of the chamber 1.

[0071] The extraction chamber 10 allows the heat-exchanged gas in the exhaust cage 2 to be extracted more effectively.

[0072] With the cooperation of the extraction chamber 10 and the extraction pipe, the gas after heat exchange can be quickly extracted and discharged to the outside of the chamber, thereby accelerating the gas renewal rate in the cooling chamber and improving the cooling efficiency.

[0073] It should be noted that the bottom of the silo 1 is provided with a plurality of rectangularly distributed discharge hoppers 11, the discharge hoppers 11 are conical, and valves 12 are provided at their bottoms.

[0074] After the rice has cooled, it falls naturally to the bottom of the silo 1 due to gravity. At this point, the rice is distributed above each discharge hopper 11.

[0075] The discharge hopper 11 is conical with a large opening at the top to facilitate the receipt of rice falling from the cooling chamber; the bottom gradually narrows to form a concentrated outlet, which helps the rice flow smoothly and reduces the risk of rice accumulation and blockage in the hopper.

[0076] Each discharge hopper 11 is equipped with a valve 12 at its bottom. The opening and closing status of the valve 12 is precisely controlled by the control system according to production needs. When rice needs to be discharged, the control system opens the corresponding valve 12, and the rice flows smoothly out of the discharge hopper 11; when discharge is not required, the valve 12 remains closed to prevent rice leakage.

[0077] By controlling the opening sequence and timing of the valves 12 at the bottom of each discharge hopper 11, orderly control of rice discharge can be achieved. This helps maintain the continuity and stability of the production line and improves production efficiency.
