Description

Technical Field

[0001] This utility model relates to the field of lactic acid bacteria fermentation technology, specifically an integrated device for the fermentation and enrichment of lactic acid bacteria. Background Technology

[0002] Lactic acid bacteria are bacteria that ferment sugars to produce lactic acid; these bacteria are found in yogurt. They are a group of microorganisms that live in the body and are beneficial to the host's health; their role in maintaining human health and regulating immune function is widely recognized.

[0003] When fermenting lactic acid bacteria, a fermentation tank is required. The fermentation tank needs an oxygen supply device to supply oxygen into the fermentation tank in order to improve the growth efficiency of lactic acid bacteria. However, when the oxygen supply device is in use, it does not have the function of dust removal and sterilization. As a result, the oxygen contains dust and harmful bacteria and is directly transported into the fermentation tank, resulting in poor fermentation effect of lactic acid bacteria. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an integrated device for the fermentation and enrichment of lactic acid bacteria stem cells, which has the advantages of filtering dust and sterilizing oxygen, thus solving the problem of not having the ability to filter dust and sterilize oxygen.

[0005] This utility model discloses an integrated device for the fermentation and enrichment of lactic acid bacteria, comprising a workbench. A fermentation tank is located on the right side of the top of the workbench, and an oxygen filtration assembly is located on the left side of the top of the workbench. The oxygen filtration assembly includes a filter box, the bottom of which is fixedly connected to the workbench. The inner cavity of the filter box contains a filter plate composed of a filter fiber layer and a polytetrafluoroethylene (PTFE) layer, with the filter fiber layer located on top of the PTFE layer. A sealing plate is located on the left side of the filter plate, and its surface is in close contact with the filter box. An air intake port is located at the bottom of the front of the filter box, and a fan is located at the top of the filter box. The input end of the fan is connected to an air intake pipe, the bottom of which penetrates and extends into the inner cavity of the filter box. The output end of the fan is connected to an air outlet pipe, the end of which, away from the fan, is connected to the fermentation tank. This utility model is the first... First, the raw materials and fermentation broth are poured into the fermentation tank through the feed inlet for fermentation. When oxygen needs to be supplied to the fermentation tank, the fan first runs, transmitting oxygen through the intake port to the filter box. The filter plates in the filter box remove dust and sterilize the oxygen. The filter fiber layer in the filter plate filters dust from the oxygen, and the polytetrafluoroethylene (PTFE) layer in the filter plate filters harmful bacteria from the oxygen. Then, the filtered oxygen is transmitted to the intake pipe, which in turn transmits it to the fan, which then transmits it to the exhaust pipe. The exhaust pipe then delivers oxygen to the fermentation tank, thereby improving the growth efficiency of lactic acid bacteria. The exhaust valve allows the fermentation tank to be vented, preventing the oxygen supply device from lacking dust removal and sterilization functions, which could result in the oxygen containing dust and harmful bacteria being directly delivered to the fermentation tank, causing poor fermentation of lactic acid bacteria.

[0006] This utility model discloses an integrated device for the fermentation and enrichment of lactic acid bacteria stems. Both ends of the inner cavity of the filter box are fixedly connected to concave plates, and the inner cavity of the concave plates is engaged with the filter plate. This utility model allows the filter plate to be easily disassembled by means of the concave plates. Only the sealing plate needs to be moved, and the filter plate is moved by the sealing plate. When the filter plate is moved out of the concave plate, the filter plate can be cleaned regularly.

[0007] The present invention relates to an integrated device for the fermentation and enrichment of lactic acid bacteria stems, wherein the sealing plate is provided with a handle on the left side, and the surface of the handle is covered with an anti-slip sleeve. The handle and the anti-slip sleeve facilitate the movement of the sealing plate, avoiding the situation where the sealing plate is inconvenient to move.

[0008] This utility model discloses an integrated device for the fermentation and enrichment of lactic acid bacteria stem cells. The fermenter has a motor at its top, and a rotating rod at its output end. The bottom of the rotating rod extends through and into the inner cavity of the fermenter. A stirring rod is mounted on the surface of the rotating rod, and stirring blades are mounted on the bottom of the rotating rod surface. The motor drives the rotating rod to rotate, which in turn drives the stirring rod and stirring blades to rotate. The stirring rod mixes the raw materials and fermentation liquid, resulting in better fermentation. The stirring blades transport the raw materials and fermentation liquid from the bottom of the fermenter cavity upwards, preventing them from settling.

[0009] This utility model discloses an integrated device for the fermentation and enrichment of lactic acid bacteria stems. The bottom of the surface of the fermentation tank is fixedly fitted with a fixing plate, and the inner cavity of the fixing plate is fixedly connected to the workbench by fixing bolts. The fixing plate and fixing bolts can fix the fermentation tank, so that the fermentation tank can be used more effectively and avoid shaking during use, which would lead to instability of the components inside the fermentation tank.

[0010] The present invention relates to an integrated device for the fermentation and enrichment of lactic acid bacteria stems, wherein the workbench is provided with support columns at the four corners of its bottom, and the bottom of the support columns is provided with anti-slip pads.

[0011] The present invention relates to an integrated device for the fermentation and enrichment of lactic acid bacteria stem cells, wherein the fermentation tank has a feed inlet on the top right side, a discharge outlet on the bottom front side of the fermentation tank, and an exhaust valve is fitted on the left side of the top of the fermentation tank cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this invention, the raw materials and fermentation broth are first poured into the fermentation tank through the feed inlet for fermentation. When oxygen needs to be supplied to the fermentation tank, the fan first runs, and the oxygen is transferred to the filter box through the air intake. The filter plate in the filter box removes dust and sterilizes the oxygen. The filter fiber layer in the filter plate can filter dust from the oxygen, and the polytetrafluoroethylene (PTFE) layer in the filter plate can filter harmful bacteria in the oxygen. Then, the filtered oxygen is transferred to the air intake pipe, and then to the fan through the air intake pipe. The fan then transfers the oxygen to the air outlet pipe, and finally to the fermentation tank for oxygen supply, thereby improving the growth efficiency of lactic acid bacteria. The exhaust valve can exhaust the gas from the fermentation tank, avoiding the situation where the oxygen supply device does not have the function of dust removal and sterilization, which would result in the oxygen containing dust and harmful bacteria being directly transported into the fermentation tank, causing poor fermentation effect of lactic acid bacteria.

[0014] 2. The concave plate of this utility model facilitates the disassembly of the filter plate. Simply move the sealing plate, which in turn moves the filter plate. Once the filter plate is removed from the concave plate, it can be cleaned regularly.

[0015] The handle and anti-slip sleeve facilitate the movement of the sealing plate, avoiding the situation where the sealing plate is inconvenient to move.

[0016] The motor drives the rotating rod to rotate, which in turn drives the stirring rod and stirring blades to rotate. The stirring rod can mix the raw materials and fermentation liquid, resulting in better fermentation. The stirring blades can transport the raw materials and fermentation liquid from the bottom of the fermentation tank upwards, preventing them from settling to the bottom.

[0017] The fermentation tank can be fixed in place by using fixing plates and bolts, which makes the fermentation tank more effective during use and prevents it from shaking, which could lead to instability of the internal components. Attached Figure Description

A sealing plate 404 is provided on the left side of the filter plate 409, and the surface of the sealing plate 404 is in close contact with the filter box 401. An air intake 407 is provided at the bottom of the front of the filter box 401. A fan 403 is provided at the top of the filter box 401. The input end of the fan 403 is connected to an air intake pipe 4010. The bottom of the air intake pipe 4010 penetrates and extends into the inner cavity of the filter box 401. The output end of the fan 403 is connected to an air outlet pipe 402. The end of the exhaust pipe 402 furthest from the blower 403 is connected to the fermentation tank 5. In this invention, the raw materials and fermentation liquid are first poured into the fermentation tank 5 through the feed inlet 10 for fermentation. When oxygen needs to be supplied to the fermentation tank 5, the blower 403 operates, transmitting oxygen through the intake port 407 to the filter box 401. The oxygen is then filtered and sterilized by the filter plate 409 within the filter box 401. The filter fiber layer 4091 within the filter plate 409 filters dust from the oxygen, and the polytetrafluoroethylene (PTFE) layer 4092 within the filter plate 409 filters out impurities in the oxygen. The oxygen is filtered to remove harmful bacteria, and then the filtered oxygen is transferred to the suction pipe 4010. The oxygen is then transferred to the blower 403, and then to the exhaust pipe 402. The oxygen is then transferred to the fermenter 5 for oxygen supply, thereby improving the growth efficiency of lactic acid bacteria. The exhaust valve 8 can be used to exhaust the gas from the fermenter 5, avoiding the situation where the oxygen supply device does not have the function of dust removal and sterilization, which would result in the oxygen containing dust and harmful bacteria being directly transported into the fermenter 5, causing poor fermentation of lactic acid bacteria.

[0027] Both ends of the inner cavity of the filter box 401 are fixedly connected to concave plates 408, and the inner cavity of the concave plates 408 is engaged with the filter plate 409. The concave plates 408 facilitate the disassembly of the filter plate 409. Simply move the sealing plate 404 to move the filter plate 409. When the filter plate 409 is moved out of the concave plates 408, the filter plate 409 can be cleaned regularly.

[0028] A handle 406 is provided on the left side of the sealing plate 404, and an anti-slip sleeve 405 is provided on the surface of the handle 406.

The surface of the rotating rod 14 is equipped with a stirring rod 11, and the bottom of the surface of the rotating rod 14 is equipped with a stirring blade 13. When the motor 9 is running, the motor 9 drives the rotating rod 14 to rotate, which in turn drives the stirring rod 11 and the stirring blade 13 to rotate. The stirring rod 11 can stir and mix the raw materials and fermentation liquid, which improves the fermentation effect. The stirring blade 13 can transport the raw materials and fermentation liquid at the bottom of the inner cavity of the fermentation tank 5 upward, preventing the raw materials and fermentation liquid from settling to the bottom.

When oxygen needs to be supplied to the fermentation tank 5, the blower 403 is started, and oxygen is transferred to the filter box 401 through the air intake 407. The oxygen is then filtered and sterilized by the filter plate 409 in the filter box 401. The filter fiber layer 4091 in the filter plate 409 can filter dust from the oxygen, and the polytetrafluoroethylene (PTFE) layer 4092 in the filter plate 409 can filter harmful bacteria in the oxygen. Then... The filtered oxygen is transferred to the suction pipe 4010, which then transfers it to the blower 403. The blower 403 then transfers the oxygen to the exhaust pipe 402, which in turn transfers it to the fermenter 5 for oxygen supply, thereby improving the growth efficiency of the lactic acid bacteria. The exhaust valve 8 can be used to exhaust the gas from the fermenter 5, preventing the oxygen supply device from lacking dust removal and sterilization functions, which would otherwise result in the oxygen containing dust and harmful bacteria being directly transported into the fermenter 5, causing poor fermentation of the lactic acid bacteria.

[0033] The motor 9 drives the rotating rod 14 to rotate, which in turn drives the stirring rod 11 and the stirring blade 13 to rotate.
