Description

Technical Field

[0001] The utility model belongs to the technical field of plant beverage production equipment, and specifically relates to a fermentation device for producing plant beverages for controlling blood sugar. Background Art

[0002] With the accelerated pace of urban life, the improved quality of life, and the changes in people's eating habits, high blood sugar, high blood lipids, and high blood pressure have gradually become the three major killers threatening human health, and are showing a trend of becoming younger.

[0003] Short-term, one-time high blood sugar does not cause serious harm to the human body (such as short-term high blood sugar that occurs under stress or when one is emotionally excited or highly nervous), but long-term high blood sugar can cause lesions in various tissues and organs throughout the body, leading to acute or chronic complications such as dehydration, electrolyte imbalance, nutritional deficiency, decreased resistance, impaired renal function, neuropathy, fundus lesions, cardiovascular and cerebrovascular diseases, diabetic foot, etc., so it is imperative to control high blood sugar.

[0004] Making beverages with Chinese herbal medicine has a long history in my country. Beverage ingredients with blood sugar control effects (such as ginseng, Chinese yam, wolfberry, Poria, Pueraria root, Astragalus, mulberry, bitter melon, Polygonatum odoratum and other plant extracts) are processed through processes such as crushing, sterilization, fermentation, and wall breaking to obtain a plant beverage that controls blood sugar. Depending on the fermentation bacteria used, aerobic fermentation or anaerobic fermentation may be required.

[0005] In the Chinese utility model patent with patent application number 202023247536.3, an efficient production device for lactic acid bacteria fermentation of traditional Chinese medicine is proposed. The main problem with this patent is that hot air will be blown into the reactor during the fermentation process, so this patent can only be used for aerobic fermentation and anaerobic fermentation cannot be performed. An anaerobic fermentation tank must be used separately for anaerobic fermentation. However, plant beverage raw materials are prone to infection during transportation, which affects the quality of plant beverages. Utility Model Content

[0029] The arrangement of the oxygenation structure 7 and the vacuum pump 8 makes the utility model applicable to the fermentation of plant beverage raw materials by different fermentation bacteria, thus improving the applicability of the utility model.

[0030] like Figure 1 As shown, the outer temperature control assembly 2 includes an outer temperature control cavity 21 arranged in a ring shape, and a plurality of outer heating elements 22 and outer cooling elements 23 arranged at intervals are fixedly installed in the outer temperature control cavity 21 .

[0031] In this embodiment, the outer layer heating element 22 may be an electric heating rod, and the outer layer cooling element 23 may be a ceramic cooling sheet.

[0032] In this embodiment, an outer fermentation temperature detection element (not shown in the figure) is arranged in the outer position area inside the fermentation tank 1, and the outer fermentation temperature detection element is used to monitor the temperature in the outer position area inside the fermentation tank 1 in real time.

[0033] When the temperature is higher than the preset maximum fermentation temperature, the outer refrigeration element 23 is used to perform a refrigeration operation to reduce the fermentation temperature in the outer position area to a preset fermentation temperature range.

[0034] On the contrary, when the temperature is lower than the preset minimum fermentation temperature, the outer layer heating element 22 is used for heating operation to increase the fermentation temperature in the outer layer position area to the preset fermentation temperature range.

[0035] The inner temperature control assembly 3 includes a plurality of first vertical tubes 31 arranged in a ring shape, each of which has an inner heating element 32 fixedly installed therein, a second vertical tube 33 provided between every two adjacent first vertical tubes 31 , and each of which has an inner cooling element 34 fixedly installed therein.

[0036] In this embodiment, the inner layer heating element 32 may be an electric heating rod, and the inner layer cooling element 34 may be a ceramic cooling sheet.

[0038] When the temperature is higher than the preset maximum fermentation temperature, the inner refrigeration element 34 is used to perform a refrigeration operation to reduce the fermentation temperature in the middle position area to a preset fermentation temperature range.

[0039] On the contrary, when the temperature is lower than the preset minimum fermentation temperature, the inner layer heating element 32 is used to perform a heating operation to increase the fermentation temperature in the middle position area to a preset fermentation temperature range.

[0040] In this embodiment, the setting of the outer temperature control component 2 and the inner temperature control component 3 ensures that the fermentation temperature at each position in the fermentation tank 1 remains consistent, avoiding the situation where there is a large difference in the fermentation degree of the plant beverage raw materials due to inconsistent fermentation temperatures at different positions, thereby ensuring the consistency of the fermentation effect and fermentation efficiency of the plant beverage raw materials.

[0042] In this embodiment, both the outer oxygenating nozzle 71 and the inner oxygenating nozzle 72 can only allow sterile air to be sprayed into the fermentation tank 1, and do not allow liquid to pass through.

[0043] like Figure 1 As shown, the oxygenation structure 7 also includes an oxygenation chamber 73 arranged in a ring shape. The oxygenation chamber 73 is arranged in the tank wall of the fermentation tank 1. The oxygenation chamber 73 is connected to an oxygenation pipe 74.

[0045] In this embodiment, sterile air needs to pass through the outer temperature control chamber 21, the first vertical pipe 31 and the second vertical pipe 33 to heat the sterile air to the fermentation temperature, thereby preventing the sterile air temperature from being too low and affecting the fermentation quality and efficiency.

[0046] At the same time, the double-layer oxygenation structure can keep the oxygen concentration in the inner and outer areas and the middle area of ​​the fermentation tank 1 consistent, ensuring the consistency of the fermentation efficiency of the plant beverage raw materials in various locations.

[0052] In the second step, sterile air is introduced into the outer temperature control chamber 21, the first vertical pipe 31 and the second vertical pipe 33 through the oxygenation pipe 74 and the oxygenation chamber 73. The sterile air is heated inside the outer temperature control chamber 21, the first vertical pipe 31 and the second vertical pipe 33 so that its temperature is within the fermentation temperature range.
