Description

Technical Field

[0001] The utility model belongs to the field of fermentation equipment, and in particular relates to a device capable of increasing the fermentation speed. Background Art

[0002] The stinky tofu brine fermentation device is a device used to accelerate and control the fermentation process of stinky tofu brine. Existing stinky tofu brine fermentation devices have many shortcomings that lead to slow fermentation under natural fermentation. During natural fermentation, microorganisms are distributed in the brine only by natural diffusion and convection, which can easily cause uneven distribution of microorganisms. Some areas have a high density of microorganisms, while others have less. This makes the fermentation progress of different parts of the brine different, and the overall fermentation speed is reduced. Moreover, the mixing of microorganisms and nutrients is not sufficient, and it is difficult for the two to come into efficient contact by relying solely on natural flow. In addition, the metabolic waste produced by fermentation cannot be effectively discharged in the brine on its own, and the gradual accumulation will inhibit the growth and metabolism of microorganisms.

[0003] To address these issues, manual intervention has been used. However, this approach has drawbacks. Manual intervention can disrupt the brine's original microbial community structure, introduce foreign bacteria, disrupt the balance between microorganisms, and potentially trigger undesirable fermentation. Furthermore, manual manipulation can easily cause physical disturbances to the brine, affecting the stability of the microbial living environment. Furthermore, the frequency and extent of manual intervention are difficult to precisely control. Excessive or inappropriate manipulation can cause unnecessary stimulation to the microorganisms, affecting their activity and negatively impacting the fermentation process. Therefore, a new structure is needed to address these technical issues. Utility Model Content

When in use, the stirring motor drives the rotating shaft and the stirring rod to rotate, so that the brine can be fully mixed in the fermentation tank. During the fermentation process of stinky tofu brine, various raw materials need to be evenly distributed.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a device for improving fermentation speed, comprising: a fermentation component, a stirring component 140 and a circulation component, the stirring component 140 is installed inside the fermentation component, and the circulation component and the aeration component are installed on the outer surface of the fermentation component, the fermentation component comprises: a fermentation tank 100 and a feed port 110, a pressure gauge 120 and the feed port 110 are installed on the upper surface of the fermentation tank 100, the aeration component comprises: an air inlet pipe 210 and an aeration pipe 220, the air inlet pipe 210 is installed on the outer surface of the aeration pipe 220, and the aeration pipe 220 is installed inside the fermentation tank 100, the circulation component comprises: a circulation pump 300, a circulation pipe 1 310 and a circulation pipe 2 320, the circulation pump 300 is installed on the lower surface of the fermentation tank 100, and the circulation pipe 1 310 and the circulation pipe 2 320 are installed on the outer surface of the circulation pump 300.

[0024] See also Figures 1 to 4 As a first embodiment of the present invention, a support leg 130 is installed on the lower side of the outer surface of the fermentation tank 100, and a stirring assembly 140 includes a stirring motor 141, a rotating shaft 142, and a stirring rod 143. The stirring motor 141 is installed at the center of the upper surface of the fermentation tank 100, and the rotating shaft 142 is installed inside the fermentation tank 100 to rotate through the stirring motor 141;

[0025] Multiple groups of stirring rods 143 in a cross-shaped structure are evenly installed on the outer surface of the rotating shaft 142. A cover plate is hingedly connected to the feed inlet 110 on the upper surface of the fermenter 100 through a lock seal. A circulating pump 300 is installed at the center of the lower surface of the fermenter 100. Three outlets are respectively provided on the left, right and lower sides of the outer surface of the circulating pump 300.

[0026] During use, the user can put the raw materials needed to prepare the stinky tofu brine into the fermentation tank 100 through the feed port 110. After the addition is completed, the user can put the required water source or other materials through the feed port 110, and then close the cover to start the fermentation operation (the fermentation process and the temperature and time required for fermentation need to be selected according to actual conditions, which will not be described here). During the fermentation process, the user can start the stirring motor 141 on the upper surface of the fermentation tank 100, so that the stirring motor 141 drives the rotation and the stirring rod 143 to stir the stinky tofu brine inside the fermentation tank 100, so that the material and the brine are fully mixed. Since the stirring motor 141 drives the rotating shaft 142 and the stirring rod 143 to rotate during use, the brine can be fully mixed in the fermentation tank 100. During the fermentation process of the stinky tofu brine, various raw materials need to be evenly distributed. Stirring can ensure that the microorganisms are in full contact with the nutrients, thereby accelerating the fermentation reaction. Compared with the case without stirring, the fermentation time will be shortened, thereby accelerating the fermentation speed.

[0027] See also Figures 1 to 4 As a second embodiment of the present invention, a circulation pipe 1 310 and a circulation pipe 2 320 are respectively installed on the left and right surfaces of the circulation pump 300. The end of the circulation pipe 1 310 away from the circulation pump 300 is connected to the lower edge of the outer surface of the fermentation tank 100, and the end of the circulation pipe 2 320 away from the circulation pump 300 is connected to the upper edge of the outer surface of the fermentation tank 100.

[0028] A filter is provided at the connection between the fermentation tank 100 and the circulation pump 300. An air inlet pipe 210 is installed on the outer surface of the fermentation tank 100. The end of the air inlet pipe 210 away from the fermentation tank 100 is connected to the air supply device.

[0029] One end of the air inlet pipe 210 away from the air supply device passes through the outer surface of the fermenter 100. An aeration pipe 220 is installed inside the fermenter 100 through the air inlet pipe 210. An aeration head is installed on the outer surface of the aeration pipe 220.

[0030] When in use, during the fermentation process, the external air supply device can be started to allow gas to enter the air inlet pipe 210, and then the gas enters the inside of the aeration pipe 220, and then the aeration head on the outer surface of the aeration pipe 220 discharges the air containing oxygen into the brine, so that the microorganisms fermenting in the brine accelerate the reaction, thereby increasing the fermentation speed (note that the specific amount of increased oxygen and the time need to be selected according to the actual situation. Although a moderate increase in oxygen has a promoting effect on fermentation, if there is too much oxygen, some problems may also occur. On the one hand, too high an oxygen concentration may cause oxidative stress, causing peroxidation of the cell membrane lipids of some microorganisms, damaging the cell structure, and affecting the normal metabolism of the microorganisms. On the other hand, excessive oxygen may promote the growth of some unwanted microorganisms. For example, some acid-producing bacteria may overgrow, causing the pH value of the brine to drop too quickly, affecting the growth of other microorganisms and the balance of the fermentation process. Therefore, when increasing oxygen to promote fermentation, it is necessary to control factors such as the amount of oxygen and ventilation time).

[0031] When the aeration assembly is in use, the user can also start the circulation pump 300 on the lower surface of the fermentation tank 100, so that the circulation pump 300 extracts the brine at the bottom of the fermentation tank 100 through the circulation pipe 1 310, and then discharges it into the fermentation tank 100 again through the circulation pipe 2 320, so that the brine at the bottom of the fermentation tank 100 is discharged to the top, thereby forming a mixing effect. When the brine is discharged through the fermentation tank 100, close the valves between the circulation pipe 1 310 and the circulation pipe 2 320 and the circulation pump 300, so that the brine is discharged from the outlet of the lower surface of the circulation pump 300. At this time, the filter at the connection between the circulation pump 300 and the fermentation tank 100 can block the brine inside the fermentation tank 100. The fermented product can be recycled, and the existence of the fermented brine increases the time for the next fermentation. When the fermented product needs to be taken out, it can be fished out through the feed port 110. During use, the aeration component can provide the aerobic microorganisms involved in the fermentation process of the stinky tofu brine with the oxygen necessary for their growth and metabolism. The air inlet pipe 210 transports the outside air (or pretreated oxygen-rich gas) to the aeration pipe 220. The aeration head on the aeration pipe 220 disperses the gas into the brine in the form of tiny bubbles. These tiny bubbles greatly increase the contact area and contact time between oxygen and brine, allowing the microorganisms to fully utilize the oxygen for aerobic respiration, thereby accelerating the fermentation speed.

[0032] The circulation pump 300 circulates the brine in the fermentation tank 100 through the circulation pipe 1 310 and the circulation pipe 2 320. During the fermentation process, the components of the brine will change with the metabolism of microorganisms and the decomposition of substances. The circulation component can prevent excessive differences in local components and ensure that the various components of the brine are evenly distributed throughout the fermentation tank 100, avoiding fermentation stagnation due to local nutrient deficiency, thereby increasing the fermentation speed.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
