Description

Technical Field

[0001] This utility model relates to a slurry spraying device, belonging to the field of brewing technology. Background Technology

[0002] Strong-aroma baijiu is made from grains as raw materials, using strong-aroma daqu (a type of starter culture) as the saccharification and fermentation agent. It undergoes solid-state fermentation in mud pits, followed by solid-state distillation, aging, and blending. No edible alcohol or coloring, aroma, or flavoring substances not produced by its own fermentation are added directly or indirectly. Yanghe strong-aroma baijiu production mainly adopts the mixed-firing five-still method, characterized by the simultaneous distillation and gelatinization of raw materials and fermented mash in the same still. After gelatinization, the mash is further diluted with water.

[0003] In the brewing process, adding liquid is a crucial step. This typically involves adding a certain amount of liquid to the fermentation liquid or distilled liquor to adjust alcohol content, improve taste, promote fermentation, or meet specific process requirements. This liquid can be water, alcohol, or other specific solutions. In actual production, after the grain mash has gelatinized, workers must first remove the mash from the still, spread it out immediately, and then pour in a liquid heated to over 90°C. The liquid should be poured evenly, and the mash should be removed periodically. This production method, with gelatinization followed by adding liquid, results in a longer cooking time for the grain mash and a higher steam consumption. Furthermore, the manual addition of liquid leads to a longer operation time and a greater physical exertion for the workers. Utility Model Content

[0004] The purpose of this invention is to provide a slurry spraying device to solve the problems of long cooking time and large steam consumption caused by gelatinizing the grain mash before adding slurry in the prior art, as well as the problem of long operation time and labor consumption caused by manual slurry addition.

[0017] This utility model provides a slurry-adding spraying device. The top plate structure is positioned above the steaming pot and includes an outer ring, an inner ring, a support rod, and a water outlet. The water outlet is connected to a nozzle.

[0027] like Figure 1 As shown, this embodiment provides a steamer top plate structure for adding slurry to the grain mash inside the steamer. In some embodiments, the top plate 8 includes an inner ring 81, an outer ring 82, a support pipe 83, and a water outlet 84. Both the inner ring 81 and the outer ring 82 are hollow tubes with diameters adapted to the size of the steamer. The support pipe 83 is located between the inner ring 81 and the outer ring 82, connecting the inner ring 81 and the outer ring 82, providing slurry to the inner ring 81, and also supporting the inner ring 81. The water outlet 84 is located on the inner ring 81 and the outer ring 82, and is used to spray the slurry. The water outlets 84 are evenly distributed on the inner ring 81 and the outer ring 82, spraying the slurry evenly onto the mash inside the steamer.

[0028] like Figure 2 As shown, in some embodiments, a nozzle 11 is connected to the outside of the outlet 84. The nozzle 11 can evenly spray the slurry into the steamer, and the diameter of the nozzle 11 is adapted to the diameter of the outlet 84. Preferably, the nozzle 11 is a spiral nozzle, which is less prone to scale buildup and provides even spraying, meeting production requirements.

[0029] Optionally, multiple support rods 83 can be provided, and the number of support rods 83 can be set according to the required support force of the inner ring 81.

[0030] Optionally, multiple water outlets 84 can be provided. Preferably, in this embodiment, six water outlets 84 are evenly distributed on the inner ring 81 of the top plate 8, and twelve water outlets 84 are evenly distributed on the outer ring 82, and the diameter of the water outlets 84 is 2mm.

[0031] like Figure 3As shown, this application also provides a slurry spraying device using a top plate 8 for slurry addition. The slurry spraying device 100 is equipped with a slurry tank 3. One end of the slurry tank 3 is connected to a deep well water pipe 1 and a steam pipe 2. The deep well water pipe 1 transports well water to the slurry tank 3 for heating, and the steam pipe 2 introduces steam into the slurry tank 3 to provide a heat source. A slurry pipe 4 is connected to the end of the slurry tank 3 away from the deep well water pipe 1 and the steam pipe 2. The end of the slurry pipe 4 away from the slurry tank 3 is connected to the top plate 8. The slurry pipe 4 transports the slurry from the slurry tank 3 to the top plate 8. The slurry is sprayed into the steam pot 9 through a nozzle 11 connected to a water outlet 84 on the top plate 8. A water pump 7 is installed on the slurry pipe 4. When the water pump 7 is powered on, it can transport the slurry through the slurry pipe 4 to the top plate 8. The power supply box 5 is connected to the water pump 7 via the wire 6, providing power to the water pump 7. For equipment safety, both the power supply box 5 and the water pump 7 are double grounded for safety protection. The top plate 8 is connected to the bracket 10, and the bracket 10 provides support for the top plate 8.

[0032] Optionally, the slurry tank 3 is equipped with an automatic control system that enables automatic water supply and automatic heating.

[0033] Optionally, the slurry pipe 4 and the top plate 8 can be connected by a metal pipe. Preferably, the slurry pipe 4 and the top plate 8 are connected by a metal flexible hose. The metal flexible hose has good flexibility, high temperature resistance, anti-scalding, and is easy to disassemble and move, and can add slurry to multiple steamers separately.

[0034] In the slurry-adding stage of the brewing process in this application, the slurry in the slurry tank 3 is first heated to above 90℃. After the acid is flushed into the still for 25-30 minutes, the water pump 7 is turned on and its frequency is adjusted to 30Hz. The water pump 7 transports the slurry from the slurry tank 3 to the top plate 8, and adds slurry to the grain mash in the still 9 through the nozzle 11. The slurry-adding time is about 5-7 minutes, and the total weight of slurry added is about 160-180kg. During the slurry-adding process, the still 9 is always kept in a steaming state, and the still 9 is heated by steam to achieve the steaming of the grain mash. After adding slurry, the soaking of the grain mash in the slurry accelerates the steaming speed, shortens the steaming time, and saves steam consumption. Actual production calculations show that the cooking time for each still (9) is reduced by approximately 20 minutes. Since this application uses the traditional five-still method for brewing, which requires repeated cooking, each group can save one hour of cooking time and one hour of steam consumption. Based on on-site steam consumption measurements, each group can save 0.3-0.5 tons of steam per shift per day, reducing water loss. Simultaneously, the addition of slurry via nozzles on the top plate ensures even distribution, significantly reducing worker workload, shortening working hours, and improving efficiency.

[0035] In actual production, three workshops were selected and experimental and control pits were set up. The experimental pits used the slurry spraying device provided in this application, while the control pits used the traditional slurry addition method. By testing and comparing some substances in the experimental and control pits of the three workshops, the physicochemical comparison data in Table 1 were obtained. The specific data are shown in Table 1.

[0036] Table 1. Physicochemical Comparison Data

[0037]

[0038] As shown in Table 1, the total acidity at the mouth of the experimental fermentation pits in the three workshops was about 10% higher than that at the mouth of the control fermentation pits; ethyl hexanoate and ethyl acetate were slightly higher, while ethyl lactate was slightly lower; and isoamyl alcohol in the experimental fermentation pits was about 30% lower than that at the mouth of the control pits. The decrease in isoamyl alcohol indicates that after the in-still slurry addition process was carried out by the slurry addition spraying device of this application, the physicochemical properties of the raw wine were good, and the typicality of the style was improved.

[0039] The process parameters of the three experimental workshops were optimized and adjusted, and the values ​​of moisture, acidity, starch and gelatinization in the mash after the process parameters of the experimental and control fermentation pits were obtained. The specific values ​​are shown in Table 2.

[0040] Table 2 Comparison of mash parameters after adjustment of supporting process parameters

[0041]

[0042] By optimizing and adjusting the supporting process parameters, the water content, acidity, and gelatinization degree of the experimental pit group were basically the same as those of the control pit group. Therefore, by using the slurry spraying device of this application to perform the slurry addition process in the still, the stability of production can be maintained by optimizing and adjusting the supporting process parameters.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
