Abstract
Description
Technical Field
[0001] This application relates to the field of food fermentation technology, and in particular to a household food fermentation device and system. Background Technology
[0002] Food fermentation, as a traditional food processing technique, has a rich cultural background and market presence. Fermented foods, with their unique flavor and relatively simple processing methods, are popular among families. Because traditional fermentation methods are low-cost and often operated by experienced middle-aged or elderly family members, household fermentation products on the market tend to cater to this demographic, being inexpensive and offering limited functionality. Currently, products widely used in intelligent fermentation are primarily employed in large-scale production in food factories, restaurants, and other commercial settings. Taking factory production as an example, most fermentation machines utilize high-powered constant temperature insulation technology to ensure scale, and are equipped with specialized product monitoring sensors for the food they produce.
[0003] In related technologies, traditional methods require manual monitoring of temperature and humidity, which is cumbersome and prone to failure. Users cannot intuitively judge the fermentation process and need to rely on experience or simplified tools. Furthermore, industrial-grade technologies (such as dedicated sensors and complex control systems) are difficult to miniaturize and are not suitable for monitoring food fermentation in home settings.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0030] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this application and not all possible implementations. Based on the embodiments in this application, those skilled in the art can obtain other embodiments without creative effort, and these embodiments are also within the protection scope of this application.
[0031] To facilitate understanding, the application scenarios of this application embodiment are first introduced. This application embodiment is applied to the scenario of monitoring household food fermentation, including rice wine fermentation, kimchi fermentation, dough fermentation, fermented tofu fermentation, yogurt fermentation, fruit wine fermentation, etc. These types of household food fermentations all have very similar fermentation processes, and this application can record and monitor these processes. Considering the scenario of home use, a technology with low power consumption, moderate capacity, and versatility is used, suitable for the home fermentation environment, and easy for most users to understand. This application embodiment focuses on filling the market gap for small-scale intelligent fermentation products, targeting home, shared rental, and other living scenarios. To meet this scenario, a small-scale monitoring and production model has been developed, and a monitoring format with living scenarios has been designed, allowing the monitoring screen to be placed in different living environments, enabling visualization of the fermentation process.
[0032] Addressing the issue that fermentation monitoring products are primarily used in large-scale production scenarios, while fermentation in home settings requires experienced personnel for supervision, resulting in poor monitoring effectiveness due to manual monitoring in home settings, this application is applicable to home users monitoring the fermentation of home food. It uses sensor components to detect environmental signals within the fermentation container, and a main control chip processes these signals to generate visual signals, which are then displayed on a fermentation monitor. This provides home users with intuitive and visual feedback on the fermentation process, thereby lowering the barrier to fermentation monitoring, ensuring fermentation success rates, improving the effectiveness of home food fermentation monitoring, and enhancing the user experience.
[0033] This application, based on a miniaturized and easy-to-use smart fermentation product for home use, fills a market gap and solves the problems of existing equipment being limited in function and complex in operation. Through visual feedback and intelligent temperature control, it lowers the barrier to entry and ensures a high success rate of fermentation (even inexperienced users can operate it). It supports a variety of fermented foods (such as rice wine, kimchi, yogurt, dough, etc.), meeting diverse family needs. Furthermore, this application provides a visual display; the fermentation indicator uses changes in the color of the display circles and the increase in the number of circles to provide intuitive feedback. Users can judge the fermentation process without professional knowledge. Targeting home users, its price is lower than industrial-grade equipment, enabling home users to monitor food fermentation.
[0034] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0035] like Figure 1 As shown, the preferred embodiment of the household food fermentation device of this application includes a fermentation container 10, a heating mechanism 20, and a fermentation display 30; a monitoring plug 11 is connected to the fermentation container 10, a main control chip 12 is provided inside the fermentation container 10 or the monitoring plug 11, a sensor assembly 13 is provided inside the fermentation container 10 or the monitoring plug 11, the main control chip 12 is connected to the fermentation display 30 and the sensor assembly 13 respectively, the heating mechanism 20 is fitted to the fermentation container 10, and the heating mechanism 20 is used to control the temperature inside the fermentation container 10;
[0036] The sensor assembly 13 is used to acquire environmental signals inside the fermentation container 10 and send them to the main control chip 12. The main control chip 12 is used to generate a visualization signal based on the environmental signals. The fermentation display 30 is used to display information about home food fermentation based on the visualization signal.
[0037] Specifically, the fermentation container 10 serves as the core reaction chamber for food fermentation, providing a sealed fermentation environment. A monitoring plug 11 is nested at the top of the fermentation container 10, and a constant temperature control system (heating mechanism 20) is integrated at the bottom. The heating mechanism 20 enables self-regulation, reducing losses caused by the difficulty in controlling temperature during traditional fermentation processes. In this embodiment, the monitoring plug 11 integrates a sensor array and a wireless transmission module, serving as a data acquisition and transmission hub at the top of the container. The monitoring plug 11 is physically nested within the fermentation container 10 and connected to the processor (main control chip 12, motherboard) via cable or wirelessly. The fermentation display 30 (wireless display screen) receives data from the processor via Bluetooth / Wi-Fi and displays the fermentation status in a graphical interface. The fermentation display 30 can display circular colors, with color gradients (light red to dark brown) and changes in quantity / volume visually reflecting the activity of the microbial community. It also simultaneously displays real-time temperature, humidity, and remaining fermentation time. The fermentation display 30 communicates wirelessly with the main control chip 12 and supports placement in various scenarios (such as kitchen countertops and refrigerator doors).
[0038] In one embodiment of this application, see Figure 2 and Figure 3 The main control chip 12 is disposed inside the monitoring plug 11, and the sensor assembly 13 is disposed inside the monitoring plug 11.
[0039] In one embodiment of this application, the fermentation display 30 is disposed on the fermentation container 10; or
[0040] The fermentation display 30 is mounted on the monitoring plug 11; or
[0041] The fermentation display 30 is isolated from the fermentation container 10 and the monitoring plug 11. (See below) Figure 1 .
[0042] Specifically, the fermentation display 30 can be placed on the fermentation platform (i.e., in an isolated setting), inside the monitoring plug 11, inside the fermentation container 10, or in any living environment, so that users can view the changes in the fermented product in real time. The fermentation time and temperature are displayed digitally, and the specific fermentation status is shown by the number and color of the dots.
[0043] In one embodiment of this application, the sensor assembly 13 includes a timer, a temperature sensor, and a humidity sensor. The timer, the temperature sensor, and the humidity sensor are respectively connected to the main control chip 12, and the temperature sensor and the humidity sensor are located below the main control chip 12.
[0044] Understandably, temperature, humidity, and fermentation progress data will be presented in a concrete visualization and connected to the fermentation display 30, which carries a processor, via Bluetooth to provide users with real-time information.
[0045] Specifically, a temperature sensor collects real-time temperature data inside the container, providing feedback signals for constant temperature control and serving as input parameters for estimating the fermentation process. The temperature sensor is directly connected to the main control chip 12, and the data is synchronized to the fermentation estimation program. A humidity sensor monitors the gas humidity content, helping to determine the stability of the fermentation environment (e.g., humidity control is needed to prevent the growth of unwanted microorganisms in rice wine fermentation). The humidity sensor is connected to the main control chip 12 and transmits data to it via an independent data channel. A time module (timer) records the fermentation duration, forming a time series with the temperature and humidity data, providing dynamic parameters for the estimation program. The timer is built into the main control chip 12 (motherboard) and uses a clock chip to implement the timing function.
[0046] It should be noted that, in response to changes in environmental data generated during the fermentation process, the product incorporates several sensors to monitor the fermentation progress: a temperature sensor to estimate the heat generation during fermentation and provide preconditions for temperature control, ensuring a suitable environment; a humidity sensor to measure the humidity content in the container's gas, estimating the fermentation environment based on ambient humidity and providing calculation data; and a time module (timer, not shown in the figure) to estimate the fermentation progress and products by calculating the fermentation time and combining it with temperature and humidity sensor data. The main control chip 12, based on temperature and humidity sensor data and time calculations, combined with processor algorithms, estimates the fermentation progress and provides visualization of the fermentation products and process. The constant temperature control system (heating mechanism 20), based on controllable power heating technology, provides corresponding heating power according to temperature sensor data, achieving real-time temperature control within a suitable range for the fermentation process, ensuring the continuous and effective fermentation. This application is applicable to the current home kitchen environment and has a large market potential.
[0047] In one embodiment of this application, as Figure 2 As shown, the sensor assembly 13 also includes a pressure sensor 15, and the monitoring plug 11 is provided with a light strip 16 (i.e., a light ring). The pressure sensor 15 and the light strip 16 are respectively connected to the main control chip 12.
[0048] The pressure sensor is used to detect the concentration of carbon dioxide gas in the fermentation container, and the light strip is used for brightness display.
[0049] When the gas inside the fermentation container 10 increases and triggers the pressure sensor 15, the pressure sensor 15 sends a brightness adjustment signal to the main control chip 12, and the main control chip 12 controls the brightness of the light strip 16 according to the brightness adjustment signal.
[0050] Understandably, this application can provide visual feedback for the fermentation process. When the gas pressure inside the bottle increases during fermentation, it will gradually trigger the pressure sensor 15 and control the LED light strip 16 to light up accordingly.
[0051] In one embodiment of this application, as Figure 3 As shown, the sensor assembly 13 also includes a carbon dioxide gas detector 14, which is connected to the main control chip 12 and is used to detect the concentration of carbon dioxide gas in the fermentation container 10.
[0052] In one embodiment of this application, as Figure 1 As shown, the fermentation container 10 includes a fermentation tank and a fermentation cover. The fermentation tank and the fermentation cover are detachably connected, and the monitoring plug 11 is disposed on the fermentation cover.
[0053] Understandably, during fermentation, detectors installed at the top of the fermenter continuously receive information about the fermentation environment inside the tank, which is then displayed as color-coded circles representing the microbial community on a wireless display screen via a processor algorithm. As fermentation progresses, the circles gradually darken from light red and light yellow to dark brown, increasing in number and size. A suitable fermentation stage is indicated by brightly colored circles. This visual language is simple and easy to understand, reducing the barrier to entry for users. Simultaneously, the display screen (fermentation display 30) also synchronously monitors real-time temperature and time data.
[0054] In one embodiment of this application, as Figure 1 As shown, the fermentation cap has a circular groove and a sealing hole that penetrates the fermentation cap, and the sealing hole is located at the center of the circular groove; the monitoring plug 11 includes a sealing structure and a plug head, the plug head is connected to the sealing structure, the sensor assembly 13 is disposed in the sealing structure, and the main control chip 12 is disposed in the plug head; the sealing structure is disposed opposite to the sealing hole, and the plug head is disposed opposite to the circular groove.
[0055] Understandably, in order to integrate with and conform to the fermented food habits of most families, this application embodiment uses monitoring and temperature control technology, which saves the steps that need to be operated while making it easy to view and monitor, increases the adjustable operation, and ensures the quality of the product.
[0056] Based on the above embodiments, this application also provides a household food fermentation system, wherein, as Figure 1 As shown, the household food fermentation system includes a household food fermentation device as described in any of the above embodiments.
[0057] In one embodiment of this application, the household food fermentation system further includes a base (fermentation platform) and a storage bottle 40. The base is provided with a first groove and a second groove. The heating mechanism 20 is disposed in the first groove, and the first groove is used to place the fermentation container 10. The second groove is used to place the storage bottle 40. The storage bottle 40 is detachably connected to the monitoring plug 11. The storage bottle 40 is used to store the liquid after household food fermentation.
[0058] In this embodiment, the display screen (fermentation display 30) is placed on the fermentation platform (base) in the product kit, or it can be placed on the monitoring plug 11, or placed in any living environment, so that users can easily view the changes in the fermented product in real time. The fermentation time and temperature are displayed digitally, and the specific fermentation status is indicated by the number and color of the dots.
[0059] The embodiments of this application can reduce the number of fermentation steps. The household food fermentation system of this application integrates a tool kit (toolbox 50) required for fermentation, which is convenient to store and use. Furthermore, a corresponding stacking position is designed for each item, making the operation process simple and convenient.
