Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of rice wine production and processing, and in particular relates to a rice cooling device for rice wine brewing. Background Art
[0002] Rice wine, also known as fermented glutinous rice, sweet wine, and formerly known as "li," is brewed from glutinous rice and is a traditional specialty of the Han ethnic group. Its primary ingredient is glutinous rice, hence the name "jiangmi wine." In northern China, fermented glutinous rice is commonly referred to as "rice wine" or "sweet wine." It is a sweet rice wine made by fermenting steamed glutinous rice with fermenter's yeast (a special microbial yeast). Its simple brewing process results in a sweet and mellow flavor. Its extremely low alcohol content makes it a popular choice. my country has a long history of brewing wine from high-quality unpolished glutinous rice, spanning over a thousand years. Rice wine has become a daily beverage for farmers. Modern rice wine is mostly produced in factories.
[0003] Currently, the core steps of rice wine brewing include soaking glutinous rice, steaming the rice, mixing the koji, and fermenting it. The key lies in selecting round glutinous rice, maintaining a temperature of 30°C to 35°C, and ensuring sterile tools. Fermentation takes 24-48 hours to produce a sweet, mellow, and fragrant rice wine. The mixing of the koji is particularly crucial. Before mixing, the steamed glutinous rice must be cooled to 30°C to 35°C. Excessively high temperatures kill the koji bacteria, while excessively low temperatures delay fermentation. Currently, glutinous rice cooling methods primarily involve air cooling (blowing) or water cooling (immersion in water). The cooling process typically involves direct, unidirectional cutting of the rice balls using multiple water jets. This breaks up any unsteamed rice into smaller pieces, ensuring that each grain comes into full contact with the cold water. However, this cooling method results in a prolonged cooling time for the rice, significantly reducing cooling efficiency. Summary of the Invention

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A rice cooling device for rice wine brewing comprises a cooling pool, a cutting assembly, a bracket, a guide block and a cylinder.

[0007] As a preferred solution of this embodiment, the cutting assembly includes a water pipe, a water jet nozzle, a connecting rod, a limit bolt and a limit ring. One end of the water pipe is connected to the limit bolt, and the other end of the water pipe is welded to the limit ring. Multiple groups of water jet nozzles are evenly installed in the middle position of the water pipe, and a connecting rod is installed at the other end of the water pipe.
[0008] As a preferred solution of this embodiment, circular holes are opened on both sides of the upper cover of the cutting assembly, water pipes are installed inside the circular holes, and the ends of the water pipes are located inside the bearing seat. The water pipes and the upper cover constitute a rotating sliding structure.
[0009] As a preferred solution of this embodiment, a first through hole is opened inside the upper end of the movable guide rail, and one end of the water pipe passes through the first through hole and is installed on the movable guide rail.
[0010] As a preferred solution of this embodiment, an arc-shaped limiting hole is opened on the outer side of the upper end of the movable guide rail, a limiting bolt is installed inside the limiting hole, and the water pipe and the movable guide rail form a rotating sliding structure.
[0011] As a preferred solution of this embodiment, two groups of grooves are provided side by side on one side of the middle position of the movable guide rail of the cutting assembly, the internal dimensions of the movable guide rail are the same as the external dimensions of one side of the guide block, and the movable guide rail and the guide block constitute a sliding structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention drives the movable guide rail to move axially left and right through the movement of the guide block. The limiting ring provided on the water pipe pushes the connecting rod to slide on the pins provided on both sides of the cooling pool, compressing the spring at the same time. When the spring is compressed into place, the water pipe will not move axially, but the cylinder continues to push the guide block, causing the guide block to continue to push the movable guide rail to move axially left and right. At this time, the limiting hole provided on the movable guide rail drives the limiting bolt to slide inside the limiting hole. The structural design of the limiting hole causes the limiting bolt to rotate, thereby rotating the water pipe. This allows the water jet nozzle to complete the movement and rotation, evenly cutting the rice sliding on the feeding funnel, making the cut rice balls smaller, increasing the contact surface between the rice and the cold water, and improving the efficiency of rice cooling.

[0020] See also Figures 1 to 8 As shown, an embodiment of the present invention provides a rice cooling device for rice wine brewing, which specifically includes a cooling pool 1, a cutting assembly 4, a bracket 7, a guide block 10 and a cylinder 12. The cooling pool 1 is fixed at the middle position of the upper end of the bracket 7, and a feeding funnel 2 is provided at one end of the cooling pool 1. Funnel reinforcement ribs 3 connected to the cooling pool 1 are welded on both sides of the back of the feeding funnel 2. An upper cover 5 is fixed to the upper end of the feeding funnel 2, and a cutting assembly 4 is provided between the feeding funnel 2 and the upper cover 5. Two groups of bearing seats 8 are symmetrically fixed on both sides of the upper end of the bracket 7, and a movable guide rail 6 is provided on one side of the cooling pool 1. A guide block 10 is slidably installed on one side of the movable guide rail 6 away from the cooling pool 1, and one side of the guide block 10 is partially abutted against the bracket 7. A cylinder 12 is provided at one end of the guide block 10, and the movable guide rail 6 is connected to the cutting assembly 4. A door 11 with multiple holes is installed on one side of the cooling pool 1. Water flows out through the holes in door 11. The water flow rate inside the cooling pool 1 (the flow rate of water sprayed by the water jet nozzle 42) is greater than the water flow rate. This allows the rice balls soaked in the cooling pool 1 to flow out through the upper end of door 11 and enter the next step in the rice wine production process. This also ensures water fluidity. Furthermore, one side of the guide block 10 partially abuts against the bracket 7, preventing the guide block 10 from moving in the opposite direction during uniaxial movement by the cylinder 12.
[0021] See also Figure 6 and Figure 7As shown, the cutting assembly 4 specifically includes a water pipe 41, a water jet nozzle 42, a connecting rod 43, a stopper 44, and a stopper ring 45. The stopper 44 is connected to one end of the water pipe 41, and the stopper ring 45 is welded to the other end of the water pipe 41. Multiple groups of water jet nozzles 42 are evenly installed in the middle of the water pipe 41, and the connecting rod 43 is installed at the other end of the water pipe 41. In this embodiment, during operation, the water jet nozzles 42 are constantly in operation through external air and water sources to cut any rice that has fallen. The structural design of the water pipe 41, connecting rod 43, and stopper 44 allows the stopper 44 to rotate and slide while simultaneously driving the water pipe 41 and connecting rod 43 to rotate and move. This allows the position and angle of the water jet nozzles 42 to be adjusted by controlling the motion of the water pipe 41.
[0022] See also Figures 1 to 4 As shown, circular holes are opened on both sides of the upper cover 5, and water pipes 41 are installed inside the circular holes. The two ends of the water pipes 41 are located inside the bearing seat 8. The water pipes 41 and the upper cover 5 form a rotating and sliding structure. The design of the upper cover 5 can prevent rice from splashing when cutting, and also prevent water from splashing when the water jet is cutting. In addition, the circular holes opened on the upper cover 5 play a supporting and limiting role in the installation of the water pipe 41. See also Figure 1 、 Figure 5 and Figure 7 As shown, a first through hole is provided inside the upper end of the movable guide rail 6, and one end of the water pipe 41 is installed on the movable guide rail 6 through the through hole. An arc-shaped limiting hole 61 is provided on the outer side of the upper end of the movable guide rail 6, and a limiting bolt 44 is installed inside the limiting hole 61. The water pipe 41 and the movable guide rail 6 form a rotating sliding structure. The distance between two adjacent groups of water jet nozzles 42 is the same as the straight length of the arc-shaped limiting hole 61 provided on the movable guide rail 6. The angular range of the water jet nozzle 42 and the feeding funnel 2 is 90°-120°. Two groups of grooves are provided side by side on one side of the middle position of the movable guide rail 6. The internal dimensions of the movable guide rail 6 are the same as the external dimensions of one side of the guide block 10. The movable guide rail 6 and the guide block 10 form a sliding structure. The structural design of the movable guide rail 6 and the guide block 10 can achieve the movement of the movable guide rail 6 perpendicular to the movement direction of the guide block 10 by controlling the guide block 10 to move forward and backward. The guide block 10 is controlled to move forward and backward, driving the movable guide rail 6 to move back and forth perpendicular to the cooling pool 1. The stopper holes 61 on the movable guide rail 6 engage the stopper bolts 44, which are controlled to rotate and slide. This causes the multiple sets of water jet nozzles 42 mounted on the water pipe 41 to rotate and move left and right, cutting the rice into more uniform and fine pieces. Furthermore, the spacing between the water jet nozzles 42 and the length of the stopper holes 61 on the movable guide rail 6 ensure that the water jet nozzles 42 can more comprehensively break up the rice balls.
[0023] See also Figure 1 、 Figure 5 and Figure 7 As shown, four sets of pins are symmetrically welded on both sides of the cooling pool 1. Two sets of second through holes are opened on the connecting rod 43 and the movable guide rail 6. One end of the pin passes through the connecting rod 43 and the movable guide rail 6 and is installed with a retaining ring. A spring 9 is installed on the outside of the pin located inside the connecting rod 43. The spring 9 is located between the connecting rod 43 and the upper column of the bracket 7. The pins on the cooling pool 1 facilitate the limitation of the movable guide rail 6 and the connecting rod 43 and control their movement direction. In addition, the structural design of the pins and retaining rings facilitates the installation, disassembly and maintenance of the movable guide rail 6 and the connecting rod 43.
[0024] When the present invention is used, the steamed rice is put into the interior of the cooling pool 1 through the feeding funnel 2. When the rice slides into the cooling pool 1 through the feeding funnel 2, the water jet nozzle 42 is kept working by the external air source and water source to cut the sliding rice and disperse the rice. The cylinder 12 is continuously extended and retracted to control the guide block 10 to move forward and backward. The movement of the guide block 10 drives the movable guide rail 6 to move left and right along the axial direction. The limit ring 45 provided on the water pipe 41 is used to control the guide block 10 to move forward and backward. It will push the connecting rod 43 to slide on the pins set on both sides of the cooling pool 1, and compress the spring 9 at the same time. When the spring 9 is compressed into place, the water pipe 41 will not move along the axial direction, but the cylinder 12 continues to push the guide block 10, which will cause the guide block 10 to continue to push the movable guide rail 6 to move left and right along the axial direction. At this time, the limiting hole 61 opened on the movable guide rail 6 will drive the limiting bolt 44 to slide inside the limiting hole 61. The structural design of the limiting hole 61 causes the limiting bolt 44 to rotate, thereby causing the water pipe 41 to rotate. As a result, the multiple groups of water jet nozzles 42 installed on the water pipe 41 can move left and right with the function of rotation. When the cylinder 12 contracts, the movable guide rail 6 loses its limit, and then the limit bolt 44 loses its limit. At this time, the spring 9 resets, and the connecting rod 43 is pushed to slide on the pin, and then the water pipe 41 is moved axially first through the cooperation of the limit ring 45, thereby pushing the movable guide rail 6 to move close to the guide block 10 through the limit bolt 44. When the movable guide rail 6 and the guide block 10 are in contact, the movable guide rail 6 will not move axially. At this time, the connecting rod 43 continues to move, which will cause the limit bolt 44 to move from a position close to the cooling pool 1 (from Figure 8 state) to a position away from the cooling pool 1 (from Figure 4 In this process, the water pipe 41 rotates, causing the water jet nozzle 42 to rotate. As the rice falls and slides in the feeding funnel 2, the left and right rotation of the water jet nozzle 42 cuts the input rice into more uniform and fine pieces.
[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0026] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
