Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a fully automatic rice wine machine. Background Technology

[0002] Rice wine, also known as fermented glutinous rice, is a traditional Chinese fermented food. Its traditional production process typically involves multiple steps, including soaking rice, steaming rice, cooling, mixing with yeast, and fermentation. This process is not only cumbersome and time-consuming, but also requires extremely high standards of hygiene in the operating environment and the experience of the operator. This makes it difficult to guarantee the success rate and quality consistency of homemade rice wine.

[0003] To simplify the brewing process, some automated rice wine machines have emerged on the market. Existing rice wine machines can typically automate steps such as steaming, stirring, and fermentation. Some machines also have cooling functions, such as spraying cooling water onto the steamed rice or using air cooling, and automatically adding yeast after the temperature drops to a set value.

[0004] However, existing automated solutions still have several shortcomings. First, in the cooling stage, some equipment fails to promptly vent the large amount of residual boiling water and steam in the pot after steaming. This enormous residual heat not only severely slows down the subsequent cooling rate and increases the energy consumption of the refrigeration system, but also creates a warm water environment during the cooling process that easily breeds bacteria, which is one of the main reasons for fermentation failure or the production of a sour odor. Second, improper cooling methods lead to uneven temperatures. For example, using methods such as cooling the outside of the container or simple internal air cooling or spraying can easily result in the surface of the rice being too cold while the inside remains scorching hot due to the dense packing of the rice. This uneven temperature makes it impossible for temperature sensors to obtain the true average temperature of the rice as a whole, leading to misjudgments by the control system regarding the optimal timing for adding the yeast. Since the activity of the yeast is extremely sensitive to temperature, adding it too early or too late will directly affect the fermentation process, resulting in low alcohol yield, poor flavor, or even complete fermentation failure. In addition, most existing equipment is not fully automated and cannot automatically complete auxiliary processes such as rice soaking water discharge, secondary fermentation water replenishment, and automatic cleaning. It also lacks the ability to finely control multi-stage fermentation.

[0005] Therefore, there is an urgent need for a fully automatic rice wine machine that can achieve fully automatic control, efficient and uniform cooling, precise addition of yeast, and diverse fermentation functions. Utility Model Content

[0015] The preferred technical solution of this utility model can also produce at least the following technical effects: 1. Proactively draining boiling water improves cooling efficiency and hygiene: By proactively draining the boiling water from the pot immediately after steaming, the negative impact of residual heat on the refrigeration system is completely eliminated, and the total cooling time is significantly shortened. At the same time, this operation eliminates the risk of bacterial growth in a warm water environment, preventing fermentation failure. 2. Achieving rapid and uniform water cooling: An innovative "pre-cooling water supply + stirring water cooling" mode is adopted. The refrigeration unit pre-cools the water in the storage container. After the boiling water in the steamer body is drained, cold water is injected into the steamer body and sprayed onto the rice. Simultaneously, the stirring blades stir the steamed glutinous rice, ensuring thorough mixing and heat exchange with the cold water. This method provides rapid cooling (from 100℃ to approximately 30℃ within minutes), allowing the high-temperature material to fully contact and exchange heat with the cooling medium within the sealed container. This achieves rapid, uniform, and hygienic cooling, creating favorable conditions for subsequent fermentation and effectively preventing contamination by other microorganisms.

[0016] 3. Ensure the accuracy of yeast addition timing: Due to the rapid and uniform cooling process, the temperature detection unit can accurately reflect the true temperature of the rice as a whole. The control unit can then accurately add yeast at the optimal temperature window, avoiding fermentation failure caused by inaccurate temperature and greatly improving the success rate, stability and final quality of fermentation.

[0017] 4. Functional Integration and Optimization: The automatic drainage function quickly drains the soaking water and boiling water after steaming, preparing for the subsequent cooling process; the automatic water replenishment function adjusts the rice wine concentration during the later stages of saccharification and fermentation, promoting secondary fermentation; by setting up a dual-fermentation-starter chamber, the special fermentation-starter can be automatically and quantitatively added at the appropriate time after saccharification and fermentation, and mixed evenly to promote the fermentation process. This results in more complete fermentation of the rice wine, a richer aroma, and a better flavor profile; after the fermented rice wine is removed, the automatic cleaning function can be activated with a single button.

[0029] As an optional implementation, the automatic feeding structure includes at least two independent feeding chambers 17, each of which has a feeding control switch 18 at its bottom. The feeding control switch 18 is electrically connected to the control unit 1. During feeding, the control unit 1 controls the feeding control switch 18 to open, which opens the baffle at the bottom of the feeding chamber 17, allowing the yeast inside the feeding chamber 17 to fall onto the steaming rack 5.

[0030] As an optional implementation, the system also includes a housing 19. The cooking and fermentation vessel, control unit 1, cooling supply assembly, and drainage collection assembly are all located within the housing 19. The cooling supply assembly is located above the drainage collection assembly, and both the cooling supply assembly and the drainage collection assembly are located on the same side of the cooking and fermentation vessel. The control unit 1 is mounted on the top of the housing 19. The entire structure of the fully automatic rice wine machine is housed within the housing 19 to achieve a compact structural layout. The automated operation of the entire fully automatic rice wine machine is controlled by the control unit 1. The temperature detection unit 3 serves as an input device, sending the real-time temperature signal it detects to the control unit 1. The control unit 1 runs a preset brewing program and sends control commands to each actuator based on the program logic and the received temperature feedback. These actuators include, but are not limited to, a heating unit 2, a cooling unit 11, a stirring motor 7, a water injection solenoid valve 12, a drainage solenoid valve 15, and a feeding control switch 18. In this way, the control unit 1 constructs a closed-loop control system that can precisely coordinate various functional components to complete the complex automated brewing process.

[0031] The working process and brewing method of this fully automatic rice wine machine are described in detail below: Preparation: After washing the weighed rice (such as glutinous rice), place it in the steaming rack 5 inside the steamer body 4. Add sufficient purified water to the liquid storage container 10 and put an appropriate amount of saccharification yeast into the feeding chamber 17. After starting the preset brewing program, the control unit 1 starts to automatically execute a series of operations.

[0032] The first step is the pre-treatment process: Control unit 1 controls the cooling supply component to inject water into the steamer body 4. Specifically, control unit 1 sends an opening command to the water injection solenoid valve 12, allowing room temperature water in the liquid storage container 10 to flow into the steamer body 4 until the water level sensor detects that the water level has submerged the rice in the steaming rack 5, thus achieving automatic rice soaking. The soaking process lasts for a preset time to allow the rice grains to fully absorb water. After soaking, control unit 1 sends an opening command to the drain solenoid valve 15 to completely drain the soaking water into the collection container 14. This automated rice soaking and draining process improves the pre-brewing process and avoids the tediousness of manual operation.

[0033] Next comes the stage where steaming and pre-cooling occur simultaneously: after draining the soaking water, the control unit 1 again controls the water injection solenoid valve 12 to open, injecting an appropriate amount of clean water into the steamer body 4 as steaming water, with the water level usually below the steaming rack 5. Subsequently, the control unit 1 simultaneously initiates two parallel processes: first, it applies power to the heating unit 2 to heat the water in the steamer body 4 to generate steam to cook the rice in the steaming rack 5; second, it sends a start command to the cooling unit 11 to begin pre-cooling the purified water in the liquid storage container 10. This design, which executes the steaming and pre-cooling processes in parallel, can make full use of the time required for steaming and prepare the liquid cooling medium in advance for subsequent rapid cooling.

[0034] The core cooling and fermentation stage then begins: Control unit 1 determines whether the cooking process is complete by timing or by combining readings from temperature detection unit 3. Once cooking is finished, control unit 1 immediately executes a continuous automated cooling and fermentation process: The first step is to drain the boiling water: Control unit 1 immediately sends an opening command to drain solenoid valve 15, quickly and thoroughly draining the high-temperature boiling water and condensate remaining at the bottom of the steamer body 4 after steaming into collection container 14. This step removes a major heat source from the container, preventing this heat from continuously heating the rice, thus creating conditions for subsequent rapid cooling. Correspondingly, draining the hot water also prevents the formation of a warm water environment suitable for the growth of miscellaneous bacteria during the cooling process, significantly improving the hygiene level of the brewing process.

[0035] The second step involves injecting pre-cooled water and stirring: After confirming that the boiling water has drained, the control unit 1 immediately sends an opening command to the water injection solenoid valve 12, injecting the pre-cooled low-temperature water (i.e., liquid cooling medium) from the storage container 10 into the steamer body 4. The amount of water injected is preset to be sufficient to mix with the rice in the steaming rack 5. Simultaneously or immediately after injecting the cold water, the control unit 1 immediately starts the stirring motor 7, driving the stirring blades 8 to rotate at a medium-low speed. The tumbling action of the stirring blades 8 forces the freshly steamed, high-temperature rice grains to break up and make full and uniform direct contact with the injected cold water. Understandably, this forced convection heat transfer method is far more efficient than traditional external air cooling or static water cooling, enabling the overall temperature of the rice to drop rapidly in a very short time.

[0036] The third step is precise yeast addition based on real-time temperature: During the mixing and cooling process, the control unit 1 continuously and frequently monitors the temperature inside the steamer body 4 through the temperature detection unit 3. Due to the mixing and stirring cooling method, the temperature distribution inside the container is relatively uniform, so the reading of the temperature detection unit 3 can accurately reflect the average temperature of the rice as a whole. The program inside the control unit 1 continuously compares the real-time temperature with a preset addition temperature. This preset addition temperature is the temperature at which the yeast activity is optimal. Only when the control unit 1 determines that the monitored temperature has dropped to the preset addition temperature range, it immediately sends an opening command to the addition control switch 18. The addition control switch 18 actuates, accurately adding the saccharified yeast from the addition chamber 17 to the rice at the appropriate temperature. After addition, the stirring blades 8 can continue to stir for several tens of seconds to ensure that the yeast and rice are evenly mixed.

[0037] Next comes the constant temperature fermentation stage: after the yeast is added, the equipment automatically enters the fermentation program. The control unit 1, based on the preset fermentation temperature, intermittently starts or adjusts the power of the heating unit 2 to precisely maintain the temperature inside the steamer body 4 near the set value, providing the best environment for the saccharification of the yeast.

[0038] Secondary addition of yeast: After the saccharification and fermentation reaches the predetermined time point, the control unit 1 sends an opening command to the control switch 18 for the second addition of yeast, which automatically adds the special yeast (such as yeast) used for wine fermentation to the rice wine mash that has completed saccharification.

[0039] Water replenishment and stirring: Control unit 1 is also configured to perform automatic water replenishment during or after the second addition of yeast. At this time, it will briefly open the water injection solenoid valve 12 to add a small amount of liquid (which can be pre-cooled purified water) from the storage container 10 into the steamer body 4. The purpose of replenishing the liquid is to dilute the high-concentration sugar solution produced after saccharification, adjusting the Baume degree of the fermentation substrate to a range more suitable for yeast to carry out alcoholic fermentation, thereby increasing the alcohol yield. After water replenishment, control unit 1 will briefly start the stirring motor 7 to stir, ensuring that the newly added yeast and the replenished water are thoroughly and evenly mixed with the rice wine mash.

[0040] Alcoholic fermentation: After the second addition of yeast and water mixing, the equipment automatically enters the second stage of fermentation, namely alcoholic fermentation. Control unit 1 can adjust the target temperature for constant temperature control according to the process requirements of alcoholic fermentation. Generally, the suitable temperature for alcoholic fermentation is slightly lower than the saccharification temperature.

[0041] Automatic Cleaning: After fermentation is complete, the user can remove the brewed rice wine and select the "One-Touch Cleaning" function on the touchscreen. At this time, control unit 1 will execute the following cleaning process: Injecting cleaning liquid: The control unit 1 first controls the water injection solenoid valve 12 to open, injecting clean water from the liquid storage container 10 into the steamer body 4 as cleaning liquid until a higher preset water level is reached.

[0042] Stirring and cleaning: Subsequently, the control unit 1 controls the stirring motor 7 to operate in high-speed mode, driving the stirring blades 8 to rotate rapidly. The high-speed rotating blades generate strong water flow and eddies in the water, which powerfully washes the inner wall of the steamer body 4, the surface of the steaming rack 5, and the stirring blades 8 themselves, removing the attached residue.

[0043] Wastewater discharge: After the stirring and cleaning is completed, the control unit 1 controls the drain solenoid valve 15 to open, so that the cleaning wastewater containing residue is completely discharged into the collection container 14.

[0044] Through the above process, the fully automatic rice wine machine of this application achieves rapid, uniform, and hygienic cooling of the cooked materials through the core control logic of "draining boiling water, injecting pre-cooled water and stirring, and accurately adding yeast according to real-time temperature," while ensuring the accuracy of yeast addition, thereby helping to improve the success rate and quality stability of rice wine brewing.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
