Abstract
Description
Technical Field
[0001] This utility model relates to the field of fecal sulfur bacteria preparation technology, specifically a sealed fermentation tank for preparing fecal sulfur bacteria. Background Technology
[0002] Sealed fermentation tanks are crucial core equipment in fields such as bioengineering, food and beverage (e.g., brewing, yogurt, soy sauce), pharmaceuticals, and environmental protection (e.g., biogas production). Their core function is to maintain a strictly controlled internal environment during fermentation, including anaerobic conditions, specific gas composition, pressure, and temperature, while preventing external contamination and leakage of contents.
[0003] A fermentation tank is needed in the preparation of fecal sulfur bacteria. Chinese utility model patent CN220246082U discloses a fermentation tank for edible fungi. One side of the rotating shaft is fixedly installed above the fermentation tank. The sealing cover is movably connected to the fermentation tank. Two fixing blocks are fixedly installed at one end of the sealing cover and the fermentation tank. The internal threads of the two fixing blocks are connected to fixing bolts. A handle is fixedly connected to the top of the sealing cover. A buffer pad is fixedly installed on the rear side of the sealing cover and the fermentation tank. The two buffer pads are movably connected. This utility model allows the sealing cover to be flipped along the top of the fermentation tank via the rotating shaft. By simply using the handle to flip up the sealing cover, operators can enter the fermentation tank for cleaning. This allows the edible fungi fermentation tank to be quickly and thoroughly cleaned and disinfected, reducing the interference of residual bacteria during edible fungi fermentation and directly improving the quality of the products produced by the fermentation tank.
[0004] This invention facilitates operators entering the fermenter for cleaning. However, existing fermenters lack pretreatment functions and are not conducive to disrupting the material structure. This prevents microorganisms or their secreted enzymes from effectively accessing the nutrients encased within the intact structure. Consequently, microorganisms need to spend more time searching for and attempting to utilize the limited, accessible nutrients, resulting in slow fermentation initiation and reduced fermentation speed. Therefore, a sealed fermenter for preparing fecal sulfur bacteria is proposed to address the aforementioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a sealed fermentation tank for preparing fecal sulfur bacteria, which has advantages such as improved fermentation efficiency through pretreatment, and solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A sealed fermentation tank for preparing fecal sulfur bacteria includes a fermentation tank and a processing box. The processing box is equipped with a crushing and heating component for pretreatment to improve fermentation efficiency.
[0008] The crushing and heating assembly includes a hopper fixedly connected to the top of the processing box, a drive motor fixedly connected to the right side of the processing box, a crushing shaft fixedly connected to the output shaft of the drive motor, a stirring rod fixedly connected to the outer surface of the crushing shaft, a partition plate fixedly connected to the inner side of the processing box, and sieve holes opened on the outer surface of the partition plate. Electric heating tubes for raising and maintaining temperature are fixedly connected to both the fermentation tank and the processing box. A conveying pipe is fixedly installed at the bottom of the processing box, and a control valve is fixedly connected to the outer surface of the conveying pipe.
[0009] Furthermore, a rotary motor is fixedly connected to the bottom of the fermenter, and a rotating shaft is fixedly connected to the output shaft of the rotary motor. A stirring blade for turning over the material at the bottom is fixedly connected to the outer surface of the rotating shaft.
[0010] Furthermore, exhaust pipes are fixedly installed on both the left and right sides of the processing box, and pressure relief valves are fixedly connected to the outer surface of the exhaust pipes.
[0011] Furthermore, a controller, a temperature sensor, and a pressure sensor are fixedly connected to the outer surface of the fermenter, and the processing box is fixedly connected to the top of the fermenter.
[0012] Furthermore, a discharge pipe is fixedly installed at the bottom of the fermenter, and a solenoid valve is fixedly connected to the outer surface of the discharge pipe.
[0013] Furthermore, the conveying pipe is connected to the fermentation tank, and both the fermentation tank and the processing box are made of stainless steel.
[0014] Furthermore, the number of the agitator rods is several, and they are distributed in a ring at equal intervals inside the processing box.
[0015] Furthermore, a support frame is fixedly connected to the outside of the processing box, and support columns are fixedly connected around the bottom of the support frame.
[0016] Compared with the prior art, this utility model provides a sealed fermentation tank for preparing fecal sulfur bacteria, which has the following beneficial effects:
[0017] 1. This sealed fermentation tank for preparing fecal sulfur bacteria utilizes a pulverizing and heating component. A drive motor, via a pulverizing shaft, rotates a stirring rod at high speed inside the processing chamber, thoroughly pulverizing the material and breaking down its structure, thus reducing its volume. During this process, a partition plate intercepts the material, and a sieve screens the material by size, preventing excessively large pieces from falling further. Furthermore, the physically pulverized material is continuously heated by an electric heating element inside the processing chamber for hydrolysis. Ultimately, this effectively disrupts the material structure, increases the proportion of soluble organic matter, improves bioavailability, shortens hydrolysis time, and enhances fermentation efficiency.
[0018] 2. The sealed fermentation tank for preparing fecal sulfur bacteria, through the cooperation of a rotary motor, rotating shaft and stirring blades, can rotate and turn the material accumulated on the bottom wall of the fermentation tank to prevent it from settling. At the same time, the exhaust pipe and pressure relief valve can promptly discharge gas to the outside when the gas pressure inside the fermentation tank is too high to avoid accidents.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 3 This embodiment describes a sealed fermentation tank for preparing fecal sulfur bacteria, comprising a fermentation tank 1 and a processing chamber 2. The processing chamber 2 is equipped with a pulverizing and heating assembly for pretreatment to improve fermentation efficiency. The pulverizing and heating assembly includes a hopper 3 fixedly connected to the top of the processing chamber 2, a drive motor 4 fixedly connected to the right side of the processing chamber 2, a pulverizing shaft 5 fixedly connected to the output shaft of the drive motor 4, a stirring rod 6 fixedly connected to the outer surface of the pulverizing shaft 5, a partition plate 7 fixedly connected to the inner side of the processing chamber 2, and sieve holes 8 formed on the outer surface of the partition plate 7. Electric heating tubes 9 for increasing and maintaining temperature are fixedly connected to both the fermentation tank 1 and the processing chamber 2. A conveying pipe 10 is fixedly installed at the bottom of the processing chamber 2, and a control valve 11 is fixedly connected to the outer surface of the conveying pipe 10. The drive motor 4 can drive the stirring rod 6 to rotate at high speed inside the processing chamber 2 via the pulverizing shaft 5, thereby fully pulverizing the material, destroying its structure, and reducing its volume.
[0025] During this process, the partition plate 7 can intercept the material, and the screen hole 8 can screen the material size to prevent excessively large materials from falling further downwards.
[0026] In addition, the material that has been physically crushed is continuously heated by the electric heating tube 9 inside the processing tank 2 for hydrolysis. Ultimately, this effectively destroys the material structure, increases the proportion of soluble organic matter, improves bioavailability, shortens hydrolysis time, and increases fermentation efficiency.
[0027] In this embodiment, a rotary motor 12 is fixedly connected to the bottom of the fermentation tank 1, and a rotating shaft 13 is fixedly connected to the output shaft of the rotary motor 12. An agitator 14 for turning over the bottom material is fixedly connected to the outer surface of the rotating shaft 13. Through the cooperation of the rotary motor 12, the rotating shaft 13 and the agitator 14, the material accumulated on the bottom wall of the fermentation tank 1 can be rotated and turned over, so as to avoid the deposition of the material.
[0028] It should be noted that exhaust pipes 15 are fixedly installed on both the left and right sides of the processing tank 2. A pressure relief valve 16 is fixedly connected to the outer surface of the exhaust pipe 15. The exhaust pipe 15 and the pressure relief valve 16 can promptly discharge gas when the gas pressure inside the fermenter 1 is too high, thus avoiding accidents.
[0029] It should be noted that a controller 17, a temperature sensor 18, and a pressure sensor 19 are fixedly connected to the outer surface of the fermenter 1. The processing box 2 is fixedly connected to the top of the fermenter 1. The controller 17, temperature sensor 18, and pressure sensor 19 are used to control the equipment and monitor the internal temperature and pressure of the fermenter 1 in real time.
[0030] Specifically, a discharge pipe 20 is fixedly installed at the bottom of the fermentation tank 1, and a solenoid valve 21 is fixedly connected to the outer surface of the discharge pipe 20. The discharge pipe 20 and the solenoid valve 21 achieve the effect of discharging fermentation products.
[0031] It should be noted that the conveying pipe 10 is connected to the fermentation tank 1, and both the fermentation tank 1 and the processing box 2 are made of stainless steel.
[0032] Specifically, there are several agitators 6, which are distributed in a ring at equal intervals inside the processing box 2.
[0033] It should be noted that the processing box 2 is externally fixedly connected to a support frame 22, and support columns are fixedly connected around the bottom of the support frame 22. The support frame 22 achieves the effect of externally supporting the processing box 2.
[0034] The working principle of the above embodiments is as follows:
[0035] In operation, the staff first pours materials and water into the processing tank 2 through the hopper 3. After pouring, the drive motor 4 and the electric heating tube 9 are started in sequence. The drive motor 4 drives the crushing rod 6 to rotate at high speed inside the processing tank 2 through the crushing shaft 5, thereby fully crushing the materials, destroying their structure, and reducing their volume. During this process, the partition plate 7 intercepts the materials, and the sieve hole 8 screens the materials by size, preventing excessively large materials from falling further down. In addition, the physically crushed materials are continuously heated by the electric heating tube 9 inside the processing tank 2 for hot water hydrolysis, increasing the proportion of soluble organic matter. Finally, when the material pretreatment time reaches the set time, the control valve 11 outside the conveying pipe 10 is opened, and the pretreated materials are then conveyed to the fermentation tank 1 through the conveying pipe 10 for fermentation.
[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
