Description

Technical Field

[0001] This utility model relates to the field of koji mixing equipment, and in particular to a koji mixing equipment for producing glutinous rice wine that can assist in cooling. Background Technology

[0002] Glutinous rice wine, also known as Jiangmi wine, sweet wine, or water wine, is made primarily from glutinous rice. Traditional methods use unpolished glutinous rice, resulting in a sweet and mellow flavor with very low ethanol content, making it a popular beverage. The production process of glutinous rice wine requires cooling and mixing the cooked grains with yeast.

[0003] However, in the traditional glutinous rice wine production process, the cooked glutinous rice usually needs to be cooled before mixing with the yeast to lower its temperature and facilitate the subsequent fermentation process. However, the traditional cooling method often adopts natural cooling, placing the cooked glutinous rice in a well-ventilated place and relying on air convection to dissipate heat. However, this method has a long cooling time, low efficiency, and is greatly affected by the ambient temperature and humidity, making it difficult to ensure the consistency of cooling effect.

[0004] For example, during the hot summer months, the natural cooling effect is very limited due to the high ambient temperature. Even if the cooked glutinous rice is placed in a well-ventilated place, it will take a long time to lower its temperature to the appropriate fermentation temperature range. This not only prolongs the production cycle but also increases energy consumption and labor costs. Utility Model Content

[0005] This utility model discloses a koji mixing device for glutinous rice wine production that can assist in cooling. It aims to solve the technical problem that in the traditional glutinous rice wine production process, cooked glutinous rice usually needs to be cooled before mixing with koji to lower its temperature and facilitate the subsequent fermentation process. However, the traditional cooling method often adopts natural cooling, placing the cooked glutinous rice in a well-ventilated place and relying on air convection to dissipate heat. However, this method has a long cooling time, low efficiency, and is greatly affected by the ambient temperature and humidity, making it difficult to ensure the consistency of cooling effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mixing device for glutinous rice wine production that can assist in cooling includes a box body. The top outer wall and one side outer wall of the box body are respectively provided with a feeding hopper and a mounting plate. Both outer walls of the box body have mounting openings, and the inner walls of the mounting openings are provided with filter screens. The device also includes:

[0008] First cooling mechanism: Located inside the feed hopper, the first cooling mechanism includes a mounting rod. A third motor is provided on one inner wall of the feed hopper. The output shaft of the third motor is fixedly connected to one end of the mounting rod. A vent pipe is connected to the end of the mounting rod away from the third motor via a bearing. A first stirring blade is provided on the outer circumference of the mounting rod. Both the mounting rod and the first stirring blade have hollow interiors. The first stirring blade communicates with the interior of the mounting rod. Several equidistant vent holes are opened on one outer wall of the first stirring blade. Second cooling mechanism: Located inside the housing. Vibration mechanism: Located on the bottom outer wall of the mounting plate.

[0009] The above technical solution reduces manpower, shortens cooling time, and improves production efficiency. Specifically, cooling gas (such as cold air) is first introduced into the mounting rod and the first stirring blade through a vent pipe. Then, the third motor starts, and its output shaft drives the mounting rod to rotate. When the mounting rod rotates, the first stirring blade also rotates, stirring the cooked glutinous rice entering the feed hopper. As the first stirring blade rotates, the cooling gas is evenly released into the cooked glutinous rice through the vent holes on the first stirring blade. The cooling gas comes into full contact with the cooked glutinous rice, achieving rapid pre-cooling. Then, the cooked glutinous rice falls into the second cooling mechanism for further cooling. Finally, it falls into the vibration mechanism for thorough and even mixing and collection. This device reduces manpower, shortens cooling time, and improves production efficiency.

[0010] In a preferred embodiment, the second cooling mechanism includes a first conveyor belt, a second conveyor belt, and a third conveyor belt. The first conveyor belt is located directly below the feed hopper. A cooling chamber is provided on one side of the feed hopper. The top outer wall of the cooling chamber is provided with a mounting frame and two gears. The top inner wall of the mounting frame is provided with a first motor. The output shaft of the first motor is fixedly connected to one of the gears. The two gears mesh with each other. Fan blades are fixedly connected to the bottom outer walls of both gears. The cooling chamber and the interior of the housing are connected.

[0011] In this scheme, when the glutinous rice cooked material falls from the feed hopper into the first conveyor belt, the first conveyor belt conveys it to a position below the cooling chamber. At this time, the first motor starts, driving the gears and fan blades to rotate and generate airflow. The airflow passes through the inside of the cooling chamber and exchanges heat with the glutinous rice cooked material, thereby reducing the temperature of the glutinous rice cooked material. Then, the glutinous rice cooked material continues to be conveyed to the second and third conveyor belts, thereby increasing the residence time of the glutinous rice cooked material inside the chamber and extending the heat dissipation time. Finally, the glutinous rice cooked material is conveyed to the vibration mechanism to mix it.

[0012] In a preferred embodiment, the vibration mechanism includes a feeding box, the bottom outer wall of which has a fixing opening, the feeding box being slidably connected to the inner wall of the fixing opening, the bottom outer wall of the mounting plate having a second motor and a connecting rod, the output shaft of the second motor being fixedly connected to a first mounting wheel, one end of the connecting rod being connected to a second mounting wheel via a bearing, a connecting belt being sleeved on the outer walls of the first and second mounting wheels, a fixing post being provided on the top outer wall of the second mounting wheel near its edge, and a connecting plate being provided on one side outer wall of the feeding box, the connecting plate being sleeved on the fixing post.

[0013] In this solution, when it is necessary to mix the cooled glutinous rice material for koji preparation, the second motor is started. The output shaft of the second motor rotates, driving the first mounting wheel to rotate. Through the connecting belt, the rotation of the first mounting wheel is transmitted to the second mounting wheel. The rotation of the second mounting wheel drives the fixed column to make a circular motion. Based on the principle of eccentric wheel and under the limiting action of the fixed opening, the feeding box moves back and forth within the mounting opening. Thus, the feeding box also forms a small-range back and forth movement with the movement of the connecting plate. This vibration prevents the glutinous rice material from accumulating inside the feeding box. Combined with the rotation of the second stirring blade, the glutinous rice material is mixed evenly for koji preparation.

[0014] As described above, a koji-mixing device for glutinous rice wine production that can assist in cooling includes a housing. The top outer wall and one side outer wall of the housing are respectively provided with a feeding hopper and a mounting plate. Mounting openings are provided on both sides of the housing, and the inner wall of each mounting opening is provided with a filter screen. The device also includes: a first cooling mechanism located inside the feeding hopper, comprising a mounting rod; a third motor located on one side inner wall of the feeding hopper; the output shaft of the third motor fixedly connected to one end of the mounting rod; a vent pipe connected to the end of the mounting rod away from the third motor via a bearing; a first stirring blade on the circumferential outer wall of the mounting rod; both the mounting rod and the first stirring blade having hollow interiors; the first stirring blade communicating with the interior of the mounting rod; and several equidistantly distributed vent holes on one side outer wall of the first stirring blade; a second cooling mechanism located inside the housing; and a vibration mechanism located on the bottom outer wall of the mounting plate. This utility model provides a koji-mixing device for glutinous rice wine production that can assist in cooling, which has the technical effects of reducing manpower, shortening cooling time, and improving production efficiency.

[0021] 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, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The present invention discloses a glutinous rice wine mixing equipment that can assist in cooling. It is mainly used in the traditional glutinous rice wine production process. Before mixing the glutinous rice with koji, the cooked glutinous rice usually needs to be cooled to lower its temperature, so as to facilitate the subsequent fermentation process. However, the traditional cooling method often adopts natural cooling, placing the cooked glutinous rice in a well-ventilated place and relying on air convection to dissipate heat. However, this method has a long cooling time, low efficiency, and is greatly affected by the ambient temperature and humidity, making it difficult to ensure the consistency of cooling effect.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A mixing device for glutinous rice wine production that can assist in cooling includes a housing 1. The top outer wall and one side outer wall of the housing 1 are respectively provided with a feeding hopper 3 and a mounting plate 7. Both sides of the outer wall of the housing 1 are provided with mounting openings. The inner wall of the mounting opening is provided with a filter screen 2. It also includes: a first cooling mechanism: located inside the feeding hopper 3. The first cooling mechanism includes a mounting rod 15. A third motor is provided on one side inner wall of the feeding hopper 3. The output shaft of the third motor is fixedly connected to one end of the mounting rod 15. The end of the mounting rod 15 away from the third motor is connected to a vent pipe through a bearing. A first stirring blade 14 is provided on the circumferential outer wall of the mounting rod 15. The interior of the mounting rod 15 and the first stirring blade 14 are hollow structures. The interior of the first stirring blade 14 is connected to the interior of the mounting rod 15. A number of equidistant vent holes 16 are provided on one side outer wall of the first stirring blade 14; a second cooling mechanism: located inside the housing 1; and a vibration mechanism: located on the bottom outer wall of the mounting plate 7.

[0024] Among them, the feeding hopper 3 has an "I" shaped structure. The feeding port and the discharge port of the feeding hopper 3 with the "I" shaped structure have a larger opening area, which facilitates the rapid and large-scale input of glutinous rice. The central vertical part is used to guide the glutinous rice into the box 1 and to stir and pre-cool it.

[0025] In the specific implementation process, the first stirring blade 14 has a spiral structure. This design enables the stirring blade to generate stronger stirring force and a wider stirring range when rotating, which helps to reduce the risk of blockage of glutinous rice cooked material inside the feed hopper 3. When the glutinous rice cooked material is evenly dispersed during the stirring process, it is less likely to form clumps or block the passage. At the same time, it is easy for cold air to be fully mixed with the glutinous rice cooked material, thereby making the glutinous rice cooked material cool down quickly.

[0026] Specifically, firstly, cooling gas (such as cold air) is introduced into the mounting rod 15 and the first stirring blade 14 through the vent pipe. Then, the third motor is started, and its output shaft drives the mounting rod 15 to rotate. When the mounting rod 15 rotates, the first stirring blade 14 also rotates, stirring the glutinous rice cooked material entering the feed hopper 3. As the first stirring blade 14 rotates, the cooling gas is evenly released into the glutinous rice cooked material through the vent hole 16 on the first stirring blade 14. The cooling gas comes into full contact with the glutinous rice cooked material, achieving rapid pre-cooling. Then, the glutinous rice cooked material falls into the second cooling mechanism for further cooling. Finally, it falls into the vibration mechanism to be fully and evenly mixed and collected. This device can reduce manpower, shorten cooling time, and improve production efficiency.

[0027] Reference Figure 2 and Figure 3In a preferred embodiment, the second cooling mechanism includes a first conveyor belt 11, a second conveyor belt 12, and a third conveyor belt 13. The first conveyor belt 11 is located directly below the feed hopper 3. A cooling chamber is provided on one side of the feed hopper 3. The top outer wall of the cooling chamber is provided with a mounting frame and two gears 5. The top inner wall of the mounting frame is provided with a first motor 4. The output shaft of the first motor 4 is fixedly connected to one of the gears 5. The two gears 5 mesh with each other. Fan blades 17 are fixedly connected to the bottom outer walls of both gears 5. The cooling chamber and the interior of the housing 1 are connected.

[0028] It should be noted that, during use, the first conveyor belt 11, the second conveyor belt 12, and the third conveyor belt 13 can be equipped with special scraping devices to prevent some cooked glutinous rice from sticking to their surfaces. This avoids the accumulation of cooked glutinous rice on the surfaces of these conveyor belts. Since this device is primarily designed to assist in cooling the cooked glutinous rice, the scraping devices are not shown in the attached drawings.

[0029] The first conveyor belt 11 and the third conveyor belt 13 are arranged parallel to each other, the second conveyor belt is arranged parallel to the horizontal plane, and the first conveyor belt 11 and the third conveyor belt 13 are inclined downward.

[0030] Specifically, when the cooked glutinous rice falls from the feed hopper 3 into the first conveyor belt 11, the first conveyor belt 11 conveys it to a position below the cooling chamber. At this time, the first motor 4 starts, driving the gear 5 and the fan blade 17 to rotate, generating airflow. The airflow passes through the interior of the cooling chamber and exchanges heat with the cooked glutinous rice, thereby reducing the temperature of the cooked glutinous rice. Then, the cooked glutinous rice continues to be conveyed to the second conveyor belt 12 and the third conveyor belt 13, thereby increasing the residence time of the cooked glutinous rice inside the box 1 and extending the heat dissipation time. Finally, the cooked glutinous rice is conveyed to the vibration mechanism to be mixed.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 In a preferred embodiment, the vibration mechanism includes a feeding box 6. A fixing opening is provided on the bottom outer wall of the box body 1. The feeding box 6 is slidably connected to the inner wall of the fixing opening. A second motor 20 and a connecting rod are provided on the bottom outer wall of the mounting plate 7. The output shaft of the second motor 20 is fixedly connected to a first mounting wheel 8. One end of the connecting rod is connected to a second mounting wheel 10 through a bearing. A connecting belt 9 is sleeved on the outer wall of the first mounting wheel 8 and the second mounting wheel 10. A fixing post is provided on the top outer wall of the second mounting wheel 10 near the edge. A connecting plate 19 is provided on one side outer wall of the feeding box 6. The connecting plate 19 is sleeved on the fixing post.

[0032] The feeding box 6 is equipped with a second stirring blade 18 inside. A fourth motor is installed on one inner wall of the feeding box 6. The output shaft of the fourth motor is fixedly connected to the second stirring blade 18. A connection port is opened on the bottom outer wall of the feeding box 6. A limit plate is slidably connected to the inner wall of the connection port. A handle 21 is installed on one outer wall of the limit plate. When the cooked glutinous rice is conveyed to the feeding box 6, the fourth motor starts and drives the second stirring blade 18 to rotate. The cooked glutinous rice and the yeast water are stirred and mixed. After the mixing is completed, the handle 21 is pulled to pull out the limit plate, and then the cooked glutinous rice will be discharged from the feeding box 6. This setting realizes the stirring and mixing of cooked glutinous rice and yeast water.

[0033] Specifically, when it is necessary to mix the cooled glutinous rice material, the second motor 20 is started. The output shaft of the second motor 20 rotates, driving the first mounting wheel 8 to rotate. Through the connecting belt 9, the rotation of the first mounting wheel 8 is transmitted to the second mounting wheel 10. The rotation of the second mounting wheel 10 drives the fixed column to make a circular motion. According to the principle of eccentric wheel and under the limiting action of the fixed opening, the feeding box 6 moves back and forth in the mounting opening. Thus, the feeding box 6 also forms a small range of back and forth movement with the movement of the connecting plate 19. This vibration prevents the glutinous rice material from accumulating inside the feeding box 6. Combined with the rotation of the second stirring blade 18, the glutinous rice material is mixed evenly.

[0034] Working principle: In use, cooling gas, such as cold air, is first introduced into the mounting rod 15 and the first stirring blade 14 through the vent pipe. Then, the third motor is started, and its output shaft drives the mounting rod 15 to rotate. When the mounting rod 15 rotates, the first stirring blade 14 also rotates, stirring the glutinous rice cooked material entering the feed hopper 3. As the first stirring blade 14 rotates, the cooling gas is evenly released into the glutinous rice cooked material through the vent hole 16 on the first stirring blade 14. The cooling gas comes into full contact with the glutinous rice cooked material, achieving rapid pre-cooling. Then, the glutinous rice cooked material falls into the second cooling mechanism for further cooling. Finally, it falls into the vibration mechanism to be fully and evenly mixed and collected.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
