Description

TECHNICAL FIELD

[0001] The present application relates to fermentation device technical field, specifically to a kind of fruit juice beverage acetic acid fermentation device. BACKGROUND

[0002] Acetic acid fermentation is one of oxidation fermentation, which refers to the process of ethanol being oxidized into acetic acid under the action of acetic acid bacteria. Fruit juice beverages often use acetic acid fermentation in the production process, so the acetic acid fermentation device becomes very important. The existing fermentation device is usually composed of a tank body, a stirrer, a temperature control system, a ventilation system, an inlet and outlet, etc. The tank body is usually made of stainless steel, which has good corrosion resistance and sealing performance. The stirrer is used to stir the fruit juice to ensure that the acetic acid bacteria and the fruit juice are in full contact, thereby promoting the fermentation process. The temperature control system maintains the appropriate temperature required for fermentation through heating or cooling devices. The ventilation system provides oxygen for the acetic acid bacteria to ensure their normal growth and metabolism. However, the existing fermentation tank usually does not have a filtering structure for the fruit juice, resulting in the presence of some fruit pulp impurities in the tank body. During the fermentation process, the fruit pulp impurities may have some impact on the fermentation, and it is not convenient to clean the tank body, which may lead to the growth of bacteria in the tank body, thereby affecting the fermentation effect.

[0003] Therefore, the present application provides a fruit juice beverage acetic acid fermentation device. SUMMARY

The second stirring structure can drive the spraying structure to rotate and spray, so that the spraying is more uniform, thereby improving the efficiency of stirring and mixing.

[0047] Workflow: Pour the juice raw materials into the storage cavity 4 through the feed pipe 9, and store the juice in the storage cavity 4. The temperature in the storage cavity 4 is lowered by the refrigeration fin 40.

When adding juice to the inner cylinder 18, the electromagnet 28 is energized to attract the rotating frame 26, so that the rotating frame 26 moves downward, and the elastic expansion rod 27 is compressed, thereby driving the second rotating shaft 19 to move downward as a whole, so that a gap is formed between the plug ball 22 and the plug ring 21, and the juice can enter the connecting cavity 20 through the gap between the plug ball 22 and the plug ring 21. The juice can be added to the inner cylinder 18. When the addition is completed, the electromagnet 28 is de-energized, and the electromagnet 28 no longer attracts the rotating frame 26, so that the elastic expansion rod 27 rebounds upward to push the rotating frame 26, so that the rotating frame 26 is reset. At this time, the plug ball 22 and the plug ring 21 are in contact, thereby achieving a sealing effect to prevent the juice in the storage cavity 4 from flowing downward. When the motor 7 drives the first rotating shaft 11 to rotate, the first rotating shaft 11 drives the second rotating shaft 19 to rotate through the limiting block 24 and the limiting slot 23, and the second rotating shaft 19 rotates to drive the stirring plate 31 to rotate, thereby stirring the inner cylinder 18. The sterile air is introduced into the inner cylinder 18 through the air inlet pipe 35, thereby ensuring the survival rate of acetic acid bacteria. The exhaust gas can be discharged into the water in the incubator 2 through the exhaust pipe 34, thereby being simply absorbed and purified by the water. The exhaust gas is discharged through the air outlet pipe 49 for further purification, and the sewage is discharged from the water outlet pipe 44. The end of the exhaust pipe 34 can be water sealed, thereby preventing external bacteria from entering the exhaust pipe 34 and causing contamination of the inner cylinder 18. When the second heating pipe 38 is started, the water on the lower side is heated by the second heating pipe 38, thereby water-bath heating the inner cylinder 18, thereby ensuring the fermentation environment in the inner cylinder 18 and improving the survival rate of acetic acid bacteria.When the fermentation tank 1 needs to be cleaned, the first heating pipe 37 and the second heating pipe 38 are powered on, so that the steam in the heat preservation box 2 enters the fermentation tank 1, that is, the fermentation tank 1 is sterilized by steam, so as to ensure the sterile environment of fermentation, improve the success rate of fermentation, and when the steam is introduced, the feeding pipe 9 is blocked, so that the steam enters the spraying rod 30, so that better high-temperature sterilization effect can be achieved, and health dead angle can be prevented.
