Description

Technical Field

[0001] This application relates to the technical field of fermentation equipment, and particularly to a multifunctional automatic fermenter. Background Art

[0002] A fermenter is a device used for microbial fermentation or cell culture. It is usually a sealed container with environmental conditions suitable for the growth and fermentation of microorganisms, such as constant temperature, stirring, aeration, etc. Fermenters used in laboratories can be used for research and production in fields such as biopharmaceuticals, biofuels, and the food industry. It can provide a controllable and reusable experimental platform for researchers.

[0003] For example, in the existing Chinese patent with the publication number CN212610573U, it discloses a multifunctional fermentation and emulsification tank, which includes a tank body. An outlet is opened at the bottom of the tank body, and a stop valve is fixedly installed at the outlet. A control switch is fixedly installed at the top of the left outer wall of the tank body. A cover body is detachably installed at the top of the tank body. Two groups of lifting rings are symmetrically installed on both sides of the top of the cover body. An inlet is opened at the top of the cover body. Four groups of hinges are symmetrically and fixedly installed at the top of the cover body. A cover plate is rotatably installed by two groups of hinges. A bearing is fixedly installed at the center of the top of the cover body, and a stirring shaft is fixedly installed on the inner ring of the bearing. Through the above-mentioned existing technology, when the motor is started to operate, the driving gear transmits power to the driven gear through the chain, and then the stirring shaft drives the stirring rod body to rotate, facilitating the emulsification and stirring work of the stirred material. After the stirring is completed, it is discharged through the outlet.

[0004] However, the above-mentioned existing technology has the following technical defects:

[0005] After the above-mentioned existing technology stirs the material to be fermented, the fermented material can only be uniformly discharged from the bottom end of the tank body through the outlet; during the fermentation process, the fermentation states of the materials at different depths in the tank body are different. Experimental researchers need to periodically take out the fermented materials at different depths for observation and research and record the fermentation conditions, and external air should be avoided from entering during the material taking process to ensure that the original fermentation environment is not damaged. The above-mentioned device cannot perform the material taking operation on the fermented materials at different depths in the tank body, and the temperature in the tank body is uncontrollable, resulting in inconvenience during the experimental research process.

[0006] Based on this, on the basis of the existing multifunctional fermentation and emulsification tank, in order to overcome the above-mentioned technical defects, there is still room for improvement. Utility Model Content

Detailed Description of the Preferred Embodiments

[0029] The following will further elaborate on this application in conjunction with the attached Figures 1-7 drawings for a more detailed description.

[0030] An embodiment of this application discloses a multifunctional automatic fermenter, which can facilitate the staff to take out the fermented materials at different depths in the fermenter for observation and research, prevent the entry of external air during the material taking process, and the temperature in the fermenter is controllable.

[0031] Referring to Figure 1 and Figure 2 as shown, this application provides a multifunctional automatic fermenter, including a device base 1 and a fermenter 11 arranged in the device base 1. A fermentation device 2 is provided on the device base 1 and the fermenter 11; it is used to crush and stir the materials used for fermentation, and during the fermentation process, it can facilitate the staff to take samples and observe the fermented materials at different depths in the fermenter 11 at any time, and can prevent external air from entering the fermenter 11 during the sampling process.

[0032] The fermentation device 2 includes a driving motor 21 arranged on the device base 1 and located below the fermenter 11. A transfer rod 22 that penetrates into the fermenter 11 is installed on the rotating end of the driving motor 21. A circular through-hole 111 for the transfer rod 22 to penetrate is opened at the bottom of the fermenter 11. A number of crushing rollers 23 and stirring rollers 24 are successively arranged on the transfer rod 22 located in the fermenter 11. It should be noted that multiple crushing rollers 23 are at the bottom position inside the fermenter 11, and the edges are relatively sharp like blades, which can crush the materials with large volume and precipitation, and can also play a stirring role at the same time. The upper end of the fermenter 11 is covered with a tank top cover 25, and a material taking mechanism 3 is provided on the tank top cover 25 for taking materials of fermented materials at different depths. A transparent glass 27 is hermetically installed on the side wall of the fermenter 11. Through the transparent glass 27, the staff can observe the fermentation situation inside the fermenter 11 in real time.

[0033] Before use, first put the materials for fermentation into the fermenter 11 through the port of the fermenter 11, and then cover the port of the fermenter 11 through the tank top cover 25. Starting the driving motor 21 to operate can drive the transfer rod 22 to rotate inside the fermenter 11, thereby driving the multiple crushing rollers 23 and stirring rollers 24 installed on the transfer rod 22 to crush and fully stir the put-in materials. During the process, the staff can observe the situation inside the fermenter 11 through the transparent glass 27; when needed, the fermented materials at different depths in the fermenter 11 can be taken out through the material taking mechanism 3.

[0034] Referring to Figure 3As shown in the figure, considering the need to take out the fermented substances at different depths in the fermenter 11, which is convenient for the staff to observe and study in real time to master the fermentation situation, the material taking mechanism 3 includes a spring rod 31, an end cover 32 and an extraction unit 4; the telescopic end of the spring rod 31 faces downward and is installed on the upper side of the tank top cover 25 through an L-shaped seat 33. The end cover 32 is inserted and covered on the tank top cover 25 and is connected to the telescopic end of the spring rod 31. The spring rod 31 always has a driving force to push the end cover 32 downward; an extraction port 251 adapted to the end cover 32 is penetrated and opened on the tank top cover 25.

[0035] Under the action of the spring rod 31, the end cover 32 always covers the extraction port 251. The extraction unit 4 is arranged on the end cover 32 and the tank top cover 25 for the staff to take out a small amount of fermented substances for observation.

[0036] Refer to Figure 3 and Figure 4 As shown in the figure, in order to prevent a large amount of external air from entering the inside of the fermenter 11 through the extraction port 251 during material taking and ensure that the original fermentation environment is not invaded, the extraction unit 4 includes an extraction tank 41, a push rod 42 and a limiting component 5; the extraction tank 41 is slidably arranged in the extraction port 251 of the tank top cover 25 and is located below the end cover 32. The push rod 42 is vertically installed in the extraction tank 41. A limiting round rod 43 that penetrates upward through the end cover 32 is arranged at the upper end of the push rod 42. A round rod hole 321 for the limiting round rod 43 to penetrate is penetrated and opened on the end cover 32.

[0037] It should be noted that the extraction tank 41, the push rod 42 and the limiting round rod 43 are fixedly connected. The limiting component 5 is arranged on the tank top cover 25 for limiting the position of the extraction tank 41 to prevent it from sliding down due to its own gravity and falling onto the fermented substances.

[0038] Refer to Figure 5 and Figure 6 As shown in the figure, since it is necessary to limit and lock the position of the extraction tank 41, the limiting component 5 includes a diamond-shaped rod 51, a limiting end block 52 and an extractor 6; the diamond-shaped rod 51 is slidably arranged on the tank top cover 25 through a locking seat 53, and one end penetrates the limiting round rod 43. A diamond-shaped hole 431 for the diamond-shaped rod 51 to penetrate is penetrated and opened on the limiting round rod 43. In the initial state, one end of the diamond-shaped rod 51 is inserted into the diamond-shaped hole 431, so as to achieve the effect of locking the position of the extraction tank 41 and prevent the extraction tank 41 from sliding downward.

[0039] The limiting end block 52 is installed at one end of the diamond-shaped rod 51 away from the limiting circular rod 43. On the one hand, the limiting end block 52 can limit the diamond-shaped rod 51. On the other hand, it is convenient for the staff to pull out the diamond-shaped rod 51 to release the locking of the limiting circular rod 43, that is, the position limitation of the extraction tank 41. The extractor 6 is arranged on the limiting circular rod 43 and the device base 1 and is used to take out the fermented substances at different depths from the extraction port 251.

[0040] Continue to refer to Figure 5 and Figure 6 As shown, in order to facilitate the staff to take out the fermented substances at different depths, the extractor 6 includes a bolt 61 arranged at the upper end of the limiting circular rod 43. An extraction rod 63 is installed on the outer side wall of the device base 1 through a side rod seat 62. An internal thread hole 631 adapted to the bolt 61 is opened at the upper end of the extraction rod 63. It should be noted that the outer diameter of the extraction rod 63 is the same as the outer diameter of the limiting circular rod 43 and is adapted to the inner diameter of the circular rod hole 321. When the limiting circular rod 43 or the extraction rod 63 is forced to pass through the circular rod hole 321, it will always fit with the inner side wall of the circular rod hole 321, thus preventing a large amount of external air from entering the fermentation tank 11 through the circular rod hole 321.

[0041] When it is necessary to take out the fermented substances in the fermentation tank 11 for observation and research, first, the staff removes the extraction rod 63 from the side rod seat 62, and then rotates and threadedly connects the end of the extraction rod 63 with the internal thread hole 631 to the bolt 61, so that the extraction rod 63 can be integrally arranged with the limiting circular rod 43, the push rod 42 and the extraction tank 41 through the threaded connection with the bolt 61. After the extraction rod 63 is rotatably connected to the bolt 61, the diamond-shaped rod 51 is pulled out to release the locking of the limiting circular rod 43, and then the extraction rod 63 is pushed downward to control the extraction tank 41 to move down to any depth, achieving the purpose of taking materials from the fermented substances at different depths.

[0042] After the material taking is completed, when the extraction rod 63 is pulled up to a certain height, the push rod 42 will contact and push the end cap 32 upward, so that the end cap 32 is separated from the extraction port 251. It should be noted that before separating from the extraction port 251, since the extraction tank 41 is already in the extraction port 251 at this time, the extraction port 251 is still in a closed state, and external air will not enter the fermentation tank 11 to affect the internal fermentation; the end cap 32 is pulled and pushed until the spring rod 31 is completely contracted and cannot be pushed up further. At this time, the upper side of the extraction tank 41 can extend out of the extraction port 251 to facilitate the staff to take out a small amount of fermented substances in the extraction tank 41. Finally, the extraction tank 41 is driven to move down and reset into the extraction port 251, and the end cap 32 is reset and re-covered on the extraction port 251 under the action of the spring rod 31. Then, the diamond-shaped rod 51 is inserted again to the diamond-shaped hole 431 of the limiting circular rod 43.

[0043] Furthermore, it realizes the effect that the staff can take a small amount of the fermented material at different depths in the fermentation tank 11 and prevent external air from entering the fermentation tank 11 during the material taking process.

[0044] Refer to Figure 7 As shown, since it is necessary to control the temperature in the fermentation tank 11 for better fermentation, a number of heating pipes 26 are equidistantly arranged in the device base 1, and a number of embedded grooves 101 for installing the heating pipes 26 are equidistantly opened in the device base 1. The staff can control the temperature in the fermentation tank 11 by adjusting the temperatures of the multiple heating pipes 26.

[0045] The implementation principle of this embodiment is as follows:

[0046] (1) Material feeding: Feed the materials to be used into the fermentation tank 11 through the port of the fermentation tank 11, and then cover the tank top cover 25 on the port of the fermentation tank 11.

[0047] (2) Thorough stirring: Start the driving motor 21 to operate, and drive the transfer rod 22 to drive the multiple crushing rollers 23 and stirring rollers 24 to crush and thoroughly stir the fed materials.

[0048] (3) Temperature control: During the process, control the temperature in the fermentation tank 11 by adjusting the temperature of the heating pipe 26. At the same time, the staff can observe the internal condition of the fermentation tank 11 through the transparent glass 27.

[0049] (4) Deep material taking: Rotate and thread one end of the internal thread hole 631 of the extraction rod 63 onto the bolt 61, then pull out the diamond-shaped rod 51 and push down the extraction rod 63 to control the extraction tank 41 to move downward to take the fermented material at different depths; then pull up the extraction rod 63 so that the upper side of the extraction tank 41 extends out of the extraction port 251, and the staff can take out the fermented material in the extraction tank 41.

[0050] All the embodiments of this specific implementation manner are the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
