Description

Technical Field

[0001] This utility model relates to the field of biofilm technology, and more specifically, to a biofilm fermentation device. Background Technology

[0002] During aerobic fermentation of biofilms, strict control of oxygen content is required. In the early stage of fermentation, oxygen promotes colony growth and reproduction; in the middle stage, the oxygen supply affects the type and quantity of products; and in the final stage, the oxygen supply significantly impacts product quality and taste. However, existing technologies cannot effectively control the oxygen content required at different stages of biofilm fermentation. Furthermore, existing technologies often directly inject air into the fermentation tank when adding oxygen, and impurities in the air can affect fermentation quality. In addition, existing technologies require timely replenishment of water during biofilm fermentation, which is mostly done manually based on experience and estimation. This makes it difficult to accurately control the amount of water added, which can easily reduce the subsequent fermentation effect of the biofilm. Therefore, this invention proposes a biofilm fermentation device to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-2This utility model provides a technical solution: a biofilm fermentation device, including two fermentation tanks 10, with a base 20 on one side of each fermentation tank 10. An oxygen control component and auxiliary components are mounted on the base 20. The oxygen control component includes an air purifier 2103 mounted on top of the base 20. The air purifier 2103 is a "Belker air purifier" or other industrial air purifier, which can remove dust and other impurities from the air to prevent these impurities from affecting the fermentation effect of the biofilm. An air pump 2104 is mounted on the air purifier 2103. An air supply pipe 2105 is located at the output end of the air pump 2104, and a diversion pipe 2106 is located at one end of the air supply pipe 2105. The two ends of the diversion pipe 2106 extend into the interior of the two fermenters 10, respectively. When the oxygen content inside the fermenter 10 is insufficient, air can be introduced through the air purifier 2103 and then delivered by the air pump 2104 through the diversion pipe 2106 to the interior of the two fermenters 10 to supplement the oxygen content inside the fermenter 10. This provides sufficient oxygen for the biofilm at each stage of fermentation to improve the fermentation quality of the biofilm.

[0026] In this embodiment, a blower 21 is provided on the other side of the air purifier 2103. An air inlet pipe 2101 is fixed to the input end of the blower 21, and an air supply pipe 2102 is fixed to the output end of the blower 21. The other end of the air supply pipe 2102 is fixed to the air purifier 2103. The blower 21 delivers the air from the factory to the air supply pipe 2102 through the air inlet pipe 2101 and then delivers the air to the air purifier 2103 for purification.

[0027] The blower 21 and the water tank 22 are both fixedly installed on the top of the base 20. A water supply pipe 2207 is fixed on the left side of the water tank 22. When the water stored in the water tank 22 is used up, the water supply pipe 2207 can be connected to an external water source to replenish the water in the water tank 22 using a power device.

[0028] It should be noted that a ventilation fitting 2107 is fixed to the other end of the diversion pipe 2106. A multi-way valve 2108 is fixedly installed on the ventilation fitting 2107. The multi-way valve 2108 can control the oxygen delivery speed from the diversion pipe 2106 to the ventilation fitting 2107. The ventilation fitting 2107 is provided with multiple exhaust nozzles 2109 evenly distributed from top to bottom. The ventilation fitting 2107 is designed in an "E" shape to increase the contact area between oxygen and biofilm fermentation material, so that the oxygen distribution is more uniform and it is beneficial to improve the fermentation effect of biofilm.

[0029] Meanwhile, a detection element 2110 is set between the two fermenters 10, and an oxygen detector 2111 is fixedly installed on the detection element 2110. The oxygen detector 2111 is electrically connected to an external computer control terminal. Since the computer control of the oxygen detector 2111 is a common method in the prior art, it will not be described in detail in this technical solution. The oxygen detector 2111 can be a suitable model such as ERUN-QB9100, ERUN-QZ9100, or ERUN-QZ9100S. The oxygen detector 2111 can detect the oxygen concentration inside the fermenter 10 and replenish the oxygen inside the fermenter 10 according to the oxygen concentration required by the biofilm at different fermentation stages.

[0030] In this embodiment, the auxiliary components include a water tank 22 disposed on one side of the air purifier 2103, a water pump 2201 disposed on one side of the water tank 22, a water supply pipe 2202 disposed at the input end of the water pump 2201, and a water delivery pipe 2203 disposed at the output end of the water pump 2201. When the fermentation tank 10 needs to be replenished with water, the water pump 2201 is started and the water in the water tank 22 is delivered to the inside of the fermentation tank 10 through the water delivery pipe 2203 to meet the water requirements of the biofilm at different stages of fermentation.

[0031] Understandably, an electric valve 2204 is fixedly installed on the water supply pipe 2203, and a water outlet nozzle 2205 is fixedly installed at the other end of the water supply pipe 2203. A flow controller 2206 is fixedly installed on the fermentation tank 10. The flow controller 2206 can be one of the Inside electromagnetic flow meter or the Lainde intelligent technology turbine flow meter, which can control the water flow rate and is used to accurately control the amount of water added to the fermentation tank 10.

[0032] Finally, the ends of the water supply pipes 2203 extend into the interiors of the two fermenters 10.

[0033] Specifically, the working principle of this biofilm fermentation device is as follows:

[0034] During use, the oxygen detector 2111 can detect the oxygen concentration inside the fermenter 10 and replenish the oxygen inside the fermenter 10 according to the oxygen concentration required by the biofilm at different fermentation stages. Specifically, the blower 21 delivers air from the plant to the air supply duct 2102 through the air inlet duct 2101, and then to the air purifier 2103 for purification. The air purifier 2103 then passes the air through the air pump 2104, which then delivers the air through the splitter duct 2106 to the two fermenters 10 to replenish the oxygen inside the fermenter 10. The oxygen content is sufficient to provide enough oxygen for the biofilm at each stage of fermentation to improve the fermentation quality. In addition, when the biofilm needs to be replenished with water during fermentation, the water pump 2201 is started to transport water from the water storage tank 22 to the inside of the fermentation tank 10 through the water delivery pipe 2203 to meet the water needs of the biofilm at different stages of fermentation. The flow controller 2206 can control the water flow rate to accurately control the amount of water added to the fermentation tank 10, avoiding the inaccuracy of controlling the water needed by the biofilm during fermentation when adding water manually.

[0035] It should be noted that the specific models and specifications of the blower 21, air purifier 2103, air pump 2104, oxygen detector 2111, water pump 2201, and flow controller 2206 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and operating principles of the blower 21, air purifier 2103, air pump 2104, oxygen detector 2111, water pump 2201, and flow controller 2206 are clear to those skilled in the art and will not be described in detail here.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] Furthermore, the terms “first,” “second,” “third,” and “fourth” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as “first,” “second,” “third,” or “fourth” may explicitly or implicitly include at least one of those features.
