Detailed Implementation
[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0026] See Figure 1As shown, a probiotic fermentation broth filtration device includes a base 1, on which two sets of filtration mechanisms 2 for filtering the fermentation broth and a conveying mechanism 3 for conveying the fermentation broth into the filtration mechanisms 2 are arranged. The filtration mechanisms 2 are connected in parallel through corresponding pipelines and then connected to the inlet of the conveying mechanism 3. In this embodiment, the conveying mechanism 3 is a diaphragm pump. The two sets of filtration mechanisms 2 are backups of each other, so that when one of the filtration mechanisms 2 is maintained, the operation does not stop, ensuring uninterrupted production, greatly improving production efficiency and reducing the risk of production stoppage due to equipment maintenance. To achieve this purpose, manual valves 5 corresponding to each filtration mechanism 2 are arranged on the pipeline between the filtration mechanism 2 and the conveying mechanism 3. The manual valves 5 control whether to supply fermentation broth to the corresponding filtration mechanism 2 (i.e., the inlet pipe 26).
[0027] Further, see Figure 2-3 As shown, in this embodiment, the filtration mechanism 2 includes a cylindrical outer shell 21, an inner cylinder assembly 22, a cover plate 23, and a filter assembly 24; the inner cylinder assembly 22 is disposed inside the outer shell 21, forming a chamber 25 between the outer shell 21 and the inner cylinder assembly 22; the outer shell 21 is provided with an infusion pipe 26 and a drainage pipe 27 communicating with the inner cylinder assembly 22, and the outer shell 21 has an infusion port 211 and a drainage port 212 communicating with the chamber 25; the cover plate 23 covers the opening of the outer shell 21; the filter assembly 24... The probiotic fermentation broth is housed within the inner cylinder assembly 22. During operation, the probiotic fermentation broth enters the inner cylinder assembly 22 via the infusion pipe 26, is filtered by the filter assembly 24, and then discharged from the drain pipe 27 for the next processing step. During filtration, hot water flows into the chamber 25 via the infusion port 211 and flows out via the drain port 212, allowing hot water circulation within the chamber 25. This maintains the temperature of the probiotic fermentation broth entering the inner cylinder assembly 22, thereby preserving the activity of the probiotics and ensuring the quality and effectiveness of the product.
[0028] Further, see Figure 1 As shown in this embodiment, a heat exchanger 4 is also provided on the base 1. The heat exchanger 4 is connected in the pipeline between the filter mechanism 2 and the conveying mechanism 3. The heat exchanger 4 maintains the temperature of the probiotic fermentation liquid during the conveying process, thereby maintaining the activity of the probiotics and ensuring the quality and effect of the product.
[0029] Further, see Figure 1 As shown, in this embodiment, a solenoid valve 6 is provided in the drain pipe 27, and the opening and closing of the drain pipe 27 is controlled by the solenoid valve 6.
[0030] Further, see Figure 2-3 As shown, in this embodiment, the inner cylinder assembly 22 includes an outer cylinder 221 and an inner cylinder 222. The inner cylinder 222 is disposed inside the outer cylinder 221, and thermally conductive silicone 223 is filled between them. By using the thermally conductive silicone 223, heat transfer is made as uniformly as possible. A ring of protruding ribs 28 is provided on the inner sidewall of the inner cylinder 222, and the filter assembly 24 is installed through the ring of protruding ribs 28. A liquid level sensor 29 is provided on the inner sidewall of the inner cylinder 222. The liquid level sensor 29 includes upper and lower liquid level switches, which monitor the liquid level of the probiotic fermentation liquid stored in the inner cylinder 222 after filtration. Specifically, when the liquid level is lower than the lower liquid level switch, the solenoid valve 6 is controlled to close, and when the liquid level is higher than the upper liquid level switch, the solenoid valve 6 is controlled to open.
[0031] Further, see Figure 3 As shown, in this embodiment, the filter assembly 24 includes a mounting frame 241. A primary filter screen 242 is provided at the upper end of the mounting frame 241, and a fine filter screen 243 is provided at the lower end of the mounting frame 241. The primary filter screen 242 and the fine filter screen 243 are detachably fixed to the mounting frame 241 (e.g., screw connection). In this embodiment, the primary filter screen 242 is a stainless steel filter screen to intercept large particulate impurities; the fine filter screen 243 is a ceramic ultrafiltration membrane to retain tiny suspended matter. During installation, the mounting frame 241 cooperates with the annular protrusion 28 to install the filter assembly 24 in the inner cylinder 222. During operation, the probiotic fermentation liquid entering the inner cylinder 222 is filtered by the primary filter screen 242, enters the mounting frame 241 between the primary filter screen 242 and the fine filter screen 243, and is then filtered by the fine filter screen 243 before being stored at the lower end of the inner cylinder 222.
[0032] Further, see Figure 3 As shown, in this embodiment, the mounting bracket 241 is provided with a pair of handles 244. By providing the handles 244, it is convenient to assemble and disassemble the filter assembly 24. In this embodiment, the upper end of the handle 244 should meet the requirement that when the filter assembly 24 is installed in the inner cylinder 222 and the cover plate 23 is closed on the outer shell 21, the upper end of the handle 244 abuts against the inner end face of the cover plate 23, thereby preventing the filter assembly 24 from moving in the vertical direction.
[0033] Further, see Figure 1-3As shown, in this embodiment, the cover plate 23 is detachably locked to the outer shell 21 by the latch 7, and the stability of the connection between the cover plate 23 and the outer shell 21 is improved by setting the latch 7.
[0034] The working principle of this utility model is as follows:
[0035] During operation, the probiotic fermentation broth, driven by the conveying mechanism 3, is sequentially fed into the inner cylinder 222 through the heat exchanger 4 and the delivery pipe 26. After passing through the primary filter 242 and the fine filter 243, the broth is stored at the lower end of the inner cylinder 222, completing the filtration process. When the liquid level is higher than the upper liquid level switch, the control solenoid valve 6 opens, discharging the probiotic fermentation broth stored in the inner cylinder 222 to the next process. When the liquid level is lower than the lower liquid level switch, the control solenoid valve 6 closes, stopping the discharge.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
