Abstract
Description
Technical Field
[0001] This invention relates to the field of natto production technology, specifically to a fermentation and cultivation device for natto production. Background Technology
[0002] Natto is a traditional fermented food made primarily from soybeans through fermentation with Bacillus subtilis. It is rich in active substances such as nattokinase and vitamin K2, and has high nutritional value and health benefits. In the industrial production of natto, the fermentation stage is the core link that determines the quality of the product. The key lies in the precise and stable control of temperature, humidity, and oxygen supply in the fermentation environment.
[0003] However, existing natto fermentation equipment typically involves placing the starter culture in cultivation frames, which are then stacked within a temperature-controlled incubator. Since natto fermentation requires oxygen and produces waste gas, ventilation is necessary. However, the overlapping frames prevent oxygen from reaching the central frames, slowing down the fermentation process. Furthermore, the heating, humidification, and ventilation systems are often controlled on / off, lacking dynamic adjustment capabilities, leading to large temperature and humidity fluctuations that negatively impact the activity of the natto bacteria. Insufficient ventilation further exacerbates the problem. Insufficient ventilation will result in inadequate oxygen supply. Oxygen is essential for natto bacteria to perform aerobic respiration and obtain energy. Insufficient oxygen will directly inhibit the activity of natto bacteria, preventing them from starting the fermentation process normally. This will cause the soybeans to not produce strands, lack stickiness, and have no special flavor for a long time, ultimately leading to fermentation failure. On the other hand, excessive ventilation will result in excessive oxygen supply, causing the surface of the natto to lose water and form a dry and hard shell, which will hinder internal fermentation and affect the penetration of natto bacteria into the beans and the uniform fermentation. Furthermore, the fermentation state of natto with a dry surface is inconsistent with that of beans with a moist interior, resulting in inconsistent product quality. Therefore, we propose a fermentation cultivation device for natto production. Summary of the Invention
[0004] The purpose of this invention is to provide a fermentation and cultivation device for natto production, addressing the issues raised in the background art. However, because natto fermentation requires oxygen and generates waste gas, ventilation is necessary within the chamber. However, the cultivation frames often obstruct each other, preventing the oxygen from reaching the centrally located frame, thus slowing down the fermentation process. Furthermore, the heating, humidification, and ventilation systems are mostly "on / off" controls, lacking dynamic adjustment capabilities, which can cause excessive temperature or humidity fluctuations, affecting the activity of the natto bacteria. Insufficient ventilation further exacerbates the problem. Insufficient ventilation will result in inadequate oxygen supply. Oxygen is essential for natto bacteria to perform aerobic respiration and obtain energy. Insufficient oxygen will directly inhibit the activity of natto bacteria, preventing them from starting the fermentation process normally. This will cause the soybeans to not produce strands, lack stickiness, and have no special flavor for a long time, ultimately leading to fermentation failure. On the other hand, excessive ventilation will result in excessive oxygen supply, causing the surface of the natto to lose water and form a dry, hard shell, which will hinder internal fermentation and affect the penetration of natto bacteria into the beans and the uniform fermentation. Furthermore, the fermentation state of the dry natto and the moist beans inside will be inconsistent, resulting in inconsistent product quality.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please see Figures 1 to 9 The present invention provides a technical solution: a fermentation and cultivation device for natto production, comprising: a fermentation and cultivation box 1; It also includes: a detection mechanism 4, which is installed on the fermentation incubator 1 and is used to detect the temperature and humidity inside the fermentation incubator 1; The power adjustment mechanism 6 is installed on the fermentation incubator 1. The power adjustment mechanism 6 is used to adjust the temperature and humidity inside the fermentation incubator 1 according to the detection information fed back by the detection mechanism 4. An aeration mechanism 3 is installed on the fermentation incubator 1. The aeration mechanism 3 is used to control and adjust the aeration power through the power adjustment mechanism 6. The exhaust mechanism 5 is installed on the fermentation incubator 1. The exhaust mechanism 5 is used to cooperate with the aeration mechanism 3 and the exhaust operation power is controlled by the power adjustment mechanism 6.
[0020] By setting up the detection mechanism 4 and utilizing the multi-point distributed first and second temperature-conducting plates 43 and 45, the sensing range of the temperature sensor 42 and humidity sensor 44 is expanded, improving the representativeness and real-time performance of the detection data and avoiding the impact of local temperature differences on fermentation uniformity. By setting up the power adjustment mechanism 6, the contact state of the conductive iron block is controlled by an electromagnet, realizing stepless power adjustment of the air pump 34 and the vacuum pump 52, avoiding the drastic environmental fluctuations caused by the traditional "switch" control method, thus making the temperature and humidity control more stable. By setting up the air filling mechanism 3 and the air exhaust mechanism 5, and cooperating with the power adjustment mechanism 6 for control, the air intake and exhaust volume can be adjusted synchronously according to the fermentation requirements, thereby adjusting the oxygen concentration in the fermentation incubator 1, maintaining the air pressure balance and oxygen concentration stability in the chamber, and optimizing the growth environment of natto bacteria. In this way, through the cooperation of the above mechanisms, automatic closed-loop control of the fermentation process can be achieved, reducing manual intervention and improving production efficiency and batch stability.
[0021] The detection mechanism 4 includes a second placement box 41 fixedly connected to one side of the fermentation incubator 1. A temperature sensor 42 is fixedly connected to one side of the second placement box 41. One side of the temperature sensor 42 is located inside the fermentation incubator 1 and is fixedly connected with multiple first temperature-conducting plates 43 at equal intervals. A humidity sensor 44 is fixedly connected to one side of the second placement box 41. One side of the humidity sensor 44 is located inside the fermentation incubator 1 and is fixedly connected with multiple second temperature-conducting plates 45 at equal intervals. During use, the temperature sensor 42 collects temperature data at different locations in the fermentation incubator 1 in real time through multiple first temperature conductive plates 43, and collects humidity data through multiple second temperature conductive plates 45 using the humidity sensor 44, and then feeds the information back to the power regulation mechanism 6.
[0022] The power adjustment mechanism 6 includes a fourth placement box 61 fixedly connected to the outside of the fermentation incubator 1. The fourth placement box 61 has a first limiting groove 62 inside. A first limiting plate 63 is slidably connected to the inner wall of the first limiting groove 62. A first spring 64 is fixedly connected between one side of the first limiting plate 63 and one side of the inner wall of the first limiting groove 62. A first electromagnet 67 is fixedly connected to one side of the fourth placement box 61. A first rack 65 is fixedly connected to the bottom of the first limiting plate 63.

A second rack 69 is meshed with the bottom of the gear 68. A second limiting plate 610 is fixedly connected to one side of the second rack 69. The placement box 61 has a second limiting groove 611 inside that cooperates with the second limiting plate 610. The second rack 69 has a third limiting groove 612 inside. The inner wall of the third limiting groove 612 is slidably connected to a first limiting block 613. A second spring 614 is fixedly connected between one side of the first limiting block 613 and one side of the inner wall of the third limiting groove 612. A second magnet 616 is fixedly connected to one side of the first limiting block 613. A second electromagnet 615 is fixedly connected to one side of the second rack 69. An insulating box 617 is fixedly connected to the inside of the fourth placement box 61. A second conductive iron block 619 is fixedly connected to the inside of the insulating box 617. A first conductive iron block 618 is slidably connected to the inside of the insulating box 617. The first conductive iron block 618 is fixedly connected to the first limiting block 613. In use, the second conductive iron block 619 is connected to an external power supply, and the first conductive iron block 618 is connected to the inflation mechanism 3 and the deflation mechanism 5 via wires. Based on the information fed back by the temperature sensor 42, the first electromagnet 67 is energized. The magnetic poles of the first electromagnet 67 and the first magnet 66 are opposite, thus attracting the first magnet 66. This causes the first limiting plate 63 at the top of the first rack 65 to slide within the first limiting groove 62 and compress the first spring 64. This, through the transmission of the gear 68, drives the second rack 69, causing the moving second rack 69 to drive the second limiting plate 610 to slide within the second limiting groove 611, thereby driving... The first conductive iron block 618 at the bottom moves to make it contact the second conductive iron block 619 or change the contact area. According to the information fed back by the humidity sensor 44, the second electromagnet 615 is controlled to be energized. The magnetic poles of the second electromagnet 615 and the second magnet 616 are opposite, thus attracting the first limiting block 613 on one side of the second magnet 616 to move, so that it slides in the third limiting groove 612 and compresses the second spring 614. This can further adjust the contact area between the first conductive iron block 618 and the second conductive iron block 619, thereby changing the current input to the air pump 34 and the air pump 52, thus realizing stepless adjustment of their operating power.
[0023] The aeration mechanism 3 includes a spiral tube 31 fixedly connected to the inside of the fermentation incubator 1. The spiral tube 31 has multiple through holes 32 equidistantly opened inside. A first placement box 33 is fixedly connected to the outside of the fermentation incubator 1. An air pump 34 is fixedly connected to the bottom of the inside of the first placement box 33. The output end of the air pump 34 is fixedly connected to one end of the spiral tube 31.

Activated carbon 38 is fixedly connected to the inside of the filter cylinder 35 on the side of the filter element 37 away from the filter screen 36. During use, the air pump 34 operates according to the adjusted power, purifying the outside air through the filter cartridge 35, filtering dust and impurities through the filter screen 36, further filtering fine dust and microorganisms through the filter element 37, and finally sending the air into the spiral tube 31 after the activated carbon 38 adsorbs odors. The air is then evenly sprayed out through multiple through holes 32 on the spiral tube 31, providing oxygen for the natto bacteria and regulating the humidity.

[0025] It also includes a storage mechanism 2, which is installed on the fermentation incubator 1. The storage mechanism 2 is used to store natto and to seal the fermentation incubator 1.

[0026] The fermentation incubator 1 has two transparent windows 7 inside; When in use, staff can observe the internal fermentation status in real time through the two transparent windows 7 inside the fermentation incubator 1, so that they can understand the situation inside the fermentation incubator 1 without opening the box.
