Description

Technical Field

[0001] This utility model relates to the technical field of fermentation product extraction equipment, specifically a fermentation extraction device for separating and extracting probiotic fermentation products. Background Technology

[0002] Probiotics are a class of live microorganisms that have a positive effect on the health of the host. Common types include Bifidobacteria, Lactobacillus, and Lactobacillus acidophilus. With the increasing demand for gut health, immune regulation, and functional foods, the development and application of probiotics are becoming increasingly widespread. During fermentation, probiotics can produce a variety of bioactive metabolites, such as lactic acid, short-chain fatty acids, extracellular polysaccharides, and polypeptides. These fermentation products have important applications in health products, food additives, and pharmaceuticals. To obtain these functional products, the mixture after probiotic fermentation usually needs to be crushed, separated, and extracted. This mixture typically contains probiotic residues, intracellular and extracellular metabolites, and residual culture medium. Its composition is complex, with high water content and heterogeneous structure, thus placing high demands on the structural design of the processing equipment and the extraction method. Traditional probiotic fermentation product processing typically employs a single solid-liquid separation, such as using filters, centrifugation, or sedimentation equipment to separate the liquid portion from the solid, and then concentrating or drying the supernatant. However, single separation methods often fail to fully release the high-value-added components remaining in the solid phase, leading to resource waste, low extraction efficiency, and incomplete processing. Furthermore, there is a lack of capacity for graded management and on-demand processing of products obtained from different processing steps during the extraction process. Due to differences in the solubility, particle size, and distribution of different active substances in probiotic fermentation products, the components extracted at different stages and using different methods exhibit variations. Traditional equipment is mostly linear, single-flow structure, making it difficult to perform targeted graded and diverted processing based on product properties. Simultaneously, some equipment lacks flexible liquid reflux or reprocessing mechanisms, resulting in the inefficient reuse of some insufficiently extracted materials, thereby reducing overall extraction efficiency and output quality.

[0003] In summary, existing probiotic fermentation product processing equipment suffers from the following technical problems: First, the extraction method is singular, failing to fully release components with different structures and dissolved states, making efficient and in-depth extraction difficult. Second, it lacks a flexible process control mechanism, lacking the ability for graded extraction, reflux, or combined processing, making it difficult to meet the personalized requirements of different application scenarios regarding the type, purity, or proportion of extracts. Therefore, a more diversified probiotic fermentation product extraction device with multi-stage processing pathways and graded reflux capabilities is needed. This device should be able to achieve multi-method, multi-stage processing of fermentation products, such as multi-stage solid-liquid separation (e.g., a combination of physical sieving and pneumatic extrusion), combined with a multi-channel liquid conveying structure, flexibly controlling the material flow direction according to different extraction needs, balancing extraction efficiency and component separation accuracy, thereby achieving efficient, precise, and intelligent extraction of probiotic fermentation products. Summary of the Invention

[0004] This invention provides a probiotic fermentation product extraction device, which aims to achieve multi-stage separation and recycling of fermentation products, thereby improving extraction efficiency and adaptability.

[0005] The device includes a raw material processing unit for preliminary crushing of probiotic fermentation products, and a conveying component connecting the raw material processing unit and a first solid-liquid separation unit for conveying the crushed fermentation product mixture. The first solid-liquid separation unit has an internal isolation sieve plate dividing it into upper and lower chambers. The upper chamber is connected to a second solid-liquid separation unit via a first conveying pipe, and the lower chamber is connected to a first liquid storage unit via a fifth conveying pipe.

[0006] The second solid-liquid separation device has an expansion and extrusion section inside, with a guide channel on its inner wall to guide the extruded fermentation liquid to the collection section. The collection section sends the liquid product to the outside through a fourth conveying pipe. The second liquid storage section is connected to the fourth conveying pipe through a second conveying pipe and to the first conveying pipe through a third conveying pipe, for the purpose of reflux treatment of the extract.

[0007] Furthermore, the outlet end of the first liquid storage unit is connected to the first transfer pipe via the fourth transfer pipe, and the second transfer pipe is connected to the fourth transfer pipe at the starting position of the connection to the first liquid storage unit, so as to realize the distribution and convergence of different liquid flow paths.

[0008] To achieve precise control, several control valves are installed on each liquid channel: the first control valve is located on the fourth transmission pipe and is used to control the flow of liquid from the first storage unit to the first transmission pipe; the second control valve is located on the connection passage between the second solid-liquid separation device and the collection unit and is used to control the liquid entering the collection unit; the third control valve is located at the end of the fourth transmission pipe and is used to control whether the liquid is output to the outside or enters the storage system; the fourth control valve is located on the fifth transmission pipe and is used to control the connection status between the lower chamber of the first solid-liquid separation device and the first storage unit.

[0009] With the above-mentioned structural arrangement, the device of this utility model can realize the initial crushing of probiotic fermentation products, two-stage solid-liquid separation, collection of extract and multi-path circulation treatment. It has the advantages of high extraction efficiency, flexible control and compact structure, and is particularly suitable for application scenarios of graded recovery and deep processing of fermentation liquid products.

[0010] Figure 1 This is a schematic diagram of the probiotic fermentation product extraction device of this utility model. Detailed Implementation

[0011] The following will describe in detail the implementation of this utility model with reference to the embodiments, so that you can fully understand and implement how to use technical means to solve technical problems and achieve technical effects.

[0012] The probiotic fermentation product extraction device of this utility model is as follows: Figure 1 As shown, the device includes a raw material processing device 1 for preliminary crushing of probiotic fermentation products. The crushed fermentation product mixture is conveyed to the upper chamber of a first solid-liquid separation device 2 via a conveying component 4. The first solid-liquid separation device is equipped with an isolation sieve plate 5, which divides the first solid-liquid separation part into upper and lower chambers. Unfiltered material in the upper chamber of the first solid-liquid separation device 2 is conveyed to a second solid-liquid separation device 3 via a first conveying pipe 8. The second solid-liquid separation device 3 is equipped with an expansion and extrusion section 20 and a driving device for driving the expansion and extrusion section 20. The driving device can inflate the expansion and extrusion section 20 with air to expand it and extrude the probiotic fermentation products between it and the inner wall of the device. After being extruded, the probiotic fermentation products are conveyed to a collection section 13 along a guide groove 11 set on the inner wall of the second solid-liquid separation device 3. The second solid-liquid separation device 3 and the collection section 13 are controlled to open or close by a second control valve 12. The bottom of the collecting section 13 is provided with a fourth conveying pipe 15, and the end of the fourth conveying pipe 15 is provided with a third control valve 14 to control its opening and closing.

[0013] The bottom of the lower chamber of the first solid-liquid separation device 2 is connected to the first liquid storage section 6 via a fifth transfer pipe 18. A fourth control valve 16 is installed on the fifth transfer pipe 18. The first liquid storage section 6 is connected to the first transfer pipe 8 via a sixth transfer pipe 17, which is equipped with a first control valve 7. A second transfer pipe 9 is installed at the initial position where the sixth transfer pipe 17 connects to the first liquid storage section 6. The second transfer pipe 9 sequentially connects to the second liquid storage section 19 and the fourth transfer pipe 15. A control valve is installed on the second transfer pipe 9 to control the output of the first liquid storage section 6, the output of the fourth transfer pipe 15, and the input to the second liquid storage section 19. The second liquid storage section 19 also has a third transfer pipe that outputs to the first transfer pipe 8.

[0014] The working principle of this utility model is as follows: First, the primary product after probiotic fermentation is subjected to preliminary crushing by the crushing treatment device 1. The processed product is then conveyed by the conveying component 4 to the upper chamber of the first solid-liquid separation device 2, where the first solid-liquid separation device 2 filters and separates the pre-crushed product. The unfiltered product in the upper chamber of the first solid-liquid separation device 2 is conveyed by the first conveying pipe 8 to the second solid-liquid separation device 3. The fermentation product between itself and the inner wall of the second solid-liquid separation device 3 is then subjected to secondary processing by the expansion and extrusion section 20. The processed liquid product is guided, collected, and filtered along the inner wall of the second solid-liquid separation device 3, then sent to the collection section 13, and finally discharged by the fourth conveying pipe 15. If necessary, the collection section 13 sends the processed liquid into the second storage section 19 through the fourth conveying pipe 15, and then the third conveying pipe 10 connected to the second storage section 19 returns it to the first conveying pipe 8 and conveys it to the second solid-liquid separation device 3 for further processing.

[0015] Furthermore, the filtered material in the lower chamber of the first solid-liquid separation device 2 is transported to the first storage unit 6 via the fifth transfer pipe 18. Depending on the processing of the fermentation product, the filtered material can be selectively transported directly to the fourth transfer pipe 15 via the second transfer pipe 9 for further processing. If further extraction of the filtered product is required, it can be introduced into the first transfer pipe 8 via the sixth transfer pipe 17 and then transported back to the second solid-liquid separation device 3 for further processing. If it is not necessary to differentiate between the products from the first and second screenings, the liquid from the first screening is sent from the first storage unit 6 to the second storage unit 19 via the second transfer pipe 9 for multiple cycles. Thus, this device can not only perform two processing steps on the fermentation product, but also achieve the differentiation and / or merging of multi-stage processed products through the connection of multiple pipelines, thereby meeting the requirements for multi-level extraction of fermentation products.
