Description

Technical Field

[0001] The present invention relates to the field of lactic acid bacteria transformation, and in particular to a precise temperature-controlled lactic acid bacteria efficient transformation device and method. Background Art

[0002] Lactic acid bacteria conversion mainly refers to the process in which lactic acid bacteria convert fermentable carbohydrates (such as glucose, lactose, etc.) into lactic acid through a series of biochemical reactions under suitable conditions. In the conversion process, temperature is a crucial factor, which directly affects the growth rate, metabolic activity, and yield and quality of the final product of lactic acid bacteria. Traditional methods cannot accurately control fermentation conditions, resulting in a decrease in the growth rate of lactic acid bacteria, low conversion efficiency, and low substrate utilization. At the same time, the sensitivity of lactic acid bacteria to parameters such as temperature and pH value requires highly precise regulation, and traditional technologies have obvious deficiencies in this regard, causing instability in the fermentation process, further affecting lactic acid yield and purity.

[0003] To this end, Chinese patent application CN116974313B discloses a drying room temperature control system suitable for the hot drying production of lactic acid bacteria. It sets the duration of each production stage and the appropriate temperature curve corresponding to the duration, and performs real-time temperature detection and analysis on each area of ​​the drying room based on the corresponding appropriate temperature curve, thereby generating a normal temperature signal or a comprehensive temperature adjustment signal, and marking the corresponding temperature collection points as collection points to be temperature adjusted or non-temperature adjusted collection points through analysis, thereby achieving comprehensive temperature detection and analysis of the drying room and timely overall temperature adjustment and targeted local temperature adjustment. It has high control accuracy and good regulation effect, which helps to ensure the production efficiency and product quality of lactic acid bacteria hot drying.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 5 : A precise temperature-controlled lactic acid bacteria efficient conversion device, comprising a fermentation tank 1 and a stirring device 2 arranged in the fermentation tank 1, the stirring device 2 comprising a mounting seat 21 and a rotating drive component 22 for driving the mounting seat 21 to rotate, the mounting seat 21 is arranged in the fermentation tank 1, and the mounting seat 21 is provided with a stirring rod 211 for stirring the material inside the fermentation tank 1, and the stirring rod 211 is provided with a heating wire 212 for heating the material.

[0032] The present invention realizes the function of heating the material while stirring the material through the fermentation tank 1 and the stirring device 2. While heating the material, the material is continuously pushed by the rotation of the stirring rod 211, and the stirring rod 211 drives the heating wire 212 to continuously rotate to achieve the effect of continuously changing the heating position, thereby avoiding the situation of excessive local temperature difference during heating, improving the uniformity of heating, and thus achieving the purpose of improving the conversion efficiency of lactic acid bacteria, and solving the problem of excessive local temperature difference due to heating dead corners in the traditional temperature control system during heating. The bottom of the fermentation tank 1 is provided with a frame 11 for supporting the fermentation tank 1, and the bottom of the frame 11 is provided with a universal wheel 111, and the top of the fermentation tank 1 is provided with a cover body 12, and a pipe 121 for injecting material is provided on the cover body 12, and a pump body is provided on the pipe 121, and the pipe 121 is connected to the culture medium storage device, and the pump body and the culture medium storage device are not shown in the figure, and a controller for human-computer interaction is provided on the frame 11. During processing, the operator adds new culture medium material from the pipeline 121 to the fermentation tank 1 through the pump body and the culture medium storage device, and then starts the rotary drive component 22 and the heating wire 212 through the controller. After receiving the signal, the rotary drive component 22 drives the mounting base 21 to rotate, and the mounting base 21 drives the stirring rod 211 and the heating wire 212 to rotate, and during the rotation, the material is heated by the heating wire 212.

[0033] Reference Figure 3-Figure 5 : The stirring rod 211 is arc-shaped as a whole.

[0034] The present invention realizes the function of extending the heating wire 212 by setting the stirring rod 211 to be arc-shaped, thereby increasing the contact area between the heating wire 212 and the material, and further improving the heating uniformity and heating efficiency. During the processing, the rotary drive assembly 22 drives the mounting seat 21 to rotate, and the mounting seat 21 drives the stirring rod 211 to rotate. By setting the stirring rod 211 to be arc-shaped, the overall length of the stirring rod 211 can be increased. The increase in this length directly corresponds to the expansion of the coverage of the heating wire 212. The heating wire 212, which may have been limited by the length of the linear stirring rod 211, can now naturally extend with the extension of the arc-shaped stirring rod 211 to form a wider and denser heating network. In this way, not only the number of contact points between the heating wire 212 and the material is greatly increased, but also the contact mode becomes more diverse and effective, ensuring that heat can be transferred to every corner of the material more evenly and quickly. In addition, the design of the arc-shaped stirring rod 211 also subtly balances the relationship between stirring and heating. Although the direct stirring effect of the conventional linear stirring rod 211 may be slightly weakened, this weakening is compensated by the significant improvement in heating efficiency and uniformity, which far exceeds expectations. Therefore, from the perspective of overall performance, this innovative design is undoubtedly a major improvement and upgrade of the conventional stirring heating method.

[0035] Reference Figure 2-Figure 5 : A temperature sensor is provided on the stirring rod 211.

[0036] The present invention realizes the function of real-time detection of material temperature during the heating process by arranging a temperature sensor on one of the stirring rods 211, and at the same time, the effect of detecting the local temperature of each part of the material during the stirring process is achieved through the rotation of the stirring rod 211. Due to the rotation characteristics of the stirring rod 211, the temperature sensor can traverse every corner and layer of the material as the stirring action deepens. This dynamic and comprehensive temperature monitoring method effectively avoids the local overheating or temperature unevenness problems that may be caused by traditional static temperature measurement points, and ensures the overall temperature consistency of the material during the heating process.

[0037] Reference Figure 4 and Figure 5 : An auxiliary mechanism 3 is also provided on the stirring rod 211 , and the auxiliary mechanism 3 includes a spoiler 31 , and the spoiler 31 is arranged on the stirring rod 211 .

[0038] The present invention realizes the function of improving the stirring efficiency through the spoiler 31. When stirring, the material is pushed by the spoiler 31, and the movable seat 321 and the spoiler 31 are controlled to rise and fall when the mounting seat 21 and the stirring rod 211 are lifted and lowered, and the material is pushed to the upper layer or the lower layer when the spoiler 31 rotates, so as to further improve the efficiency of material dispersion and the heat dispersion efficiency of the heating wire 212. During the stirring process, as the mounting seat 21 and the stirring rod 211 move up and down, the spoiler 31 also adjusts its height position accordingly. This dynamic lifting adjustment not only ensures that the spoiler 31 can always act on the best layer of the material, but also further promotes the uniform mixing of the material and the effective transfer of heat by changing the thickness and distribution state of the material layer. In addition, when the spoiler 31 rotates during the stirring process, its unique design enables the material to be cleverly pushed to the upper layer or the lower layer of the stirring area. This vertical material flow not only breaks the stratification phenomenon that may exist in the traditional stirring method, but also enables the heat generated by the heating wire 212 to be more evenly distributed to all layers of the material. This not only improves the heat dispersion efficiency, but also ensures the overall temperature consistency of the material during the heating process, thereby achieving a better heating effect.

[0039] Reference Figure 4-Figure 7 : A support 32 is provided on the stirring rod 211, a movable seat 321 is slidably installed on the support 32, a hinged rod 311 is provided on the spoiler 31, two spoilers 31 are set as a group, the hinged rods 311 of the spoilers 31 in the same group are hinged to each other, the two spoilers 31 in the same group are installed on the same movable seat 321, and the hinged rod 311 of the spoiler 31 is connected to the movable seat 321 through a torsion spring, and a lifting device 4 for controlling the lifting and lowering of the mounting seat 21 is provided in the fermentation tank 1.

[0040] The present invention realizes the function of automatically controlling the movement and rotation of the spoiler 31 when the stirring rod 211 rotates through the hinged rod 311, the support 32 and the movable seat 321, so as to achieve the effect of automatically rotating the spoiler 31 by utilizing the resistance encountered by the stirring rod 211 when the stirring rod 211 rotates. In the process of the rotating drive assembly 22 driving the mounting seat 21 and the stirring rod 211 to rotate, the mounting seat 21 is controlled to be lifted and lowered reciprocatingly in the vertical direction by the lifting device 4. During the lifting process, the movable seat 321 is subject to the resistance of the material and has a tendency to stay in place, so that the movable seat 321 drives the spoiler 31 to deflect in the opposite direction of the moving direction, and as the stirring rod 211 rotates, the spoiler 31 is subject to the resistance of the material and tilts, and then the material is pushed toward the moving direction of the mounting seat 21 along the vertical direction by driving the tilted spoiler 31, so as to achieve the effect of continuously pushing the material in the vertical direction during the stirring process, and to avoid the situation of heat stratification while improving the stirring effect. During the stirring process, the rotary drive assembly 22, as the core power source, not only drives the mounting seat 21 and the stirring rod 211 thereon to rotate efficiently, but also ensures the continuity and stability of the stirring action through precise synchronous control. At the same time, the lifting device 4, as another key component, accurately controls the reciprocating lifting and lowering motion of the mounting seat 21 in the vertical direction. This dynamic adjustment strategy greatly enriches the stirring path and promotes the multi-dimensional mixing of materials. When the mounting seat 21 is lifted and lowered, the movable seat 321 tends to remain in place due to the influence of the material resistance. This mechanical phenomenon naturally guides the spoiler 31 to deflect in the opposite direction of movement. As the stirring rod 211 continues to rotate, the spoiler 31 is not only driven by the rotational force, but also tilted due to the reaction force of the material. This tilted state further enhances its ability to push the material. This dynamic stirring mode not only significantly improves the mixing efficiency and uniformity, but also effectively avoids the occurrence of heat accumulation and stratification by continuously breaking the static stratification of the material, thereby ensuring the temperature consistency and quality stability of the material during the stirring process.

[0041] Reference Figure 4 and Figure 7 A limit block 322 is provided on the support 32 for limiting the tilting range of the spoiler 31.

[0042] The present invention realizes the function of limiting the tilt angle of the spoiler 31 through the limit block 322 . The spoiler 31 is supported and limited by the limit block 322, so that the spoiler 31 will not be excessively deflected and stuck in the support 32. At the same time, the upper spoiler 31 is limited by the limit block 322 to control its tilt angle, so that it can have a sufficient pushing area to push the material, thereby improving the running stability of the equipment.

[0043] Reference Figure 2 and Figure 3 The rotary drive assembly 22 includes a first rotary driver 221, a reduction gear box 222 and a rotating shaft 223. The first rotary driver 221 is installed on the fermentation box. The two ends of the reduction gear box 222 are respectively connected to the driving end of the first rotary driver 221 and the rotating shaft 223. The mounting seat 21 can be slidably sleeved on the rotating shaft 223.

[0044] The present invention realizes the function of driving the mounting seat 21 to rotate through the first rotary driver 221, the reduction gear box 222 and the rotating shaft 223. The first rotary driver 221 is preferably a servo motor, and the servo motor is electrically connected to the controller; after starting the device, the controller sends a signal to the first rotary driver 221, and after receiving the signal, the first rotary driver 221 drives the rotating shaft 223 to rotate through the reduction gear box 222, and the rotating shaft 223 drives the mounting seat 21 to rotate. At the same time, the lifting device 4 drives the mounting seat 21 to reciprocate and lift, and the material in the fermentation tank 1 is evenly heated.

[0045] Reference Figure 2 and Figure 7 The lifting device 4 includes a push ring 41 and a lifting assembly 42. The push ring 41 is rotatably connected to the mounting seat 21, and the lifting assembly 42 is used to drive the push ring 41 to rise and fall.

[0046] The present invention realizes the function of driving the mounting seat 21 to rise and fall through the push ring 41 and the lifting assembly 42. The lifting assembly 42 is electrically connected to the controller; while the first rotary driver 221 drives the rotating shaft 223 to rotate, the controller sends a signal to the lifting assembly 42, and the lifting assembly 42 drives the push ring 41 to rise and fall after receiving the signal, and the push ring 41 drives the mounting seat 21 to rise and fall, and the push ring 41 is rotatably connected to the mounting seat 21, and the lifting and falling of the push ring 41 will not affect the normal rotation of the mounting seat 21. Therefore, the mounting seat 21 can maintain a continuous and stable rotation state while realizing flexible adjustment of the height, thereby improving the operating efficiency and flexibility of the entire system.

[0047] Reference Figure 2 , Figure 4 , Figure 8 and Fig.10 A support rod 411 is provided on the push ring 41, and a slider 412 is provided at the end of the support rod 411. The slider 412 slides with the inner wall of the fermentation tank 1. The lifting assembly 42 includes a second rotary driver 421 and a screw 422. The second rotary driver 421 is arranged on the fermentation tank 1, and the screw 422 is rotatably installed in the fermentation tank 1. The second rotary driver 421 is used to drive the screw 422 to rotate, and the screw 422 is threadedly connected to the slider 412.

[0048] The present invention realizes the function of driving the push ring 41 and the mounting seat 21 to rise and fall through the support rod 411, the slider 412, the second rotary driver 421 and the screw 422. The second rotary driver 421 is preferably a servo motor, which is electrically connected to the controller; after starting the device, the controller sends a signal to the first rotary driver 221, and the first rotary driver 221 drives the rotating shaft 223 to rotate through the reduction gear box 222 after receiving the signal, and the rotating shaft 223 drives the mounting seat 21 to rotate. At the same time, the controller sends a signal to the second rotary driver 421, and the second rotary driver 421 drives the screw 422 to rotate after receiving the signal, and the screw 422 drives the slider 412 threadedly connected thereto to rise and fall, and the slider 412 drives the push ring 41 to rise and fall through the support rod 411, and then pushes the mounting seat 21 to reciprocate through the push ring 41. As a component directly acting on the mounting seat 21, the lifting and lowering movement of the push ring 41 further drives the mounting seat 21 to reciprocate in the vertical direction. This dynamic process not only enriches the stirring path, but also enables the stirring mechanism on the mounting seat 21 to penetrate the material layer more deeply, achieving deeper mixing and stirring. At the same time, due to the reciprocating lifting of the mounting seat 21, the material in the fermentation tank 1 is effectively stirred, promoting the uniform distribution of heat, thereby achieving uniform heating of the material and ensuring the temperature control accuracy and reaction efficiency of the fermentation process.
