Description

Technical Field

[0001] The utility model relates to the technical field of lactic acid bacteria fermentation, in particular to a temperature control device for lactic acid bacteria fermentation. Background Art

[0002] Lactic acid bacteria are a type of microorganism that is widely distributed in nature. They are extremely widespread in nature and have rich species diversity, including at least 18 genera and more than 200 species. They can convert carbohydrates into lactic acid through the fermentation process, produce sour taste and acidity, thereby protecting food, improving taste, and increasing nutritional value. The metabolic pathway of lactic acid bacteria mainly produces energy and lactic acid through the fermentation process of sugars. During the fermentation of sugars, lactic acid bacteria break down sugars into various monosaccharides through sugar acid enzymes, and then convert monosaccharides into lactic acid through lactate dehydrogenase, while producing ATP molecules to provide energy for cells.

[0003] Lactic acid bacteria fermentation needs to be carried out in an anaerobic and sterile environment and also needs to have a suitable temperature range. In order to ensure the smooth completion of the lactic acid bacteria fermentation process, the temperature of the fermented lactic acid bacteria needs to be controlled. The fermentation process of lactic acid bacteria generally uses an airlift fermentation tank. In the airlift lactic acid bacteria fermentation, the temperature control of the lactic acid bacteria cannot be carried out by stirring to evenly diffuse the temperature in the lactic acid bacteria, resulting in uneven temperature distribution in the control of the lactic acid bacteria environment temperature during lactic acid bacteria fermentation. For this reason, we provide a temperature control device for lactic acid bacteria fermentation. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a temperature control device for lactic acid bacteria fermentation, comprising a fermentation tank 1 and a tank cover 2. The tank cover 2 is movably installed on the top of the fermentation tank 1. The internal thread of the tank cover 2 is sleeved with a fixing bolt 3. The fermentation tank 1 and the tank cover 2 are fixed together by the fixing bolt 3. A driving motor 4 is fixedly installed on the top of the tank cover 2. A screw 5 is fixedly connected to the bottom of the output shaft of the driving motor 4. A moving plate 6 is sleeved with an external thread of the screw 5. The screw 5 is driven by the driving motor 4 to rotate, and the moving plate 6 can be moved up and down along the moving plate 6, thereby driving the temperature sensor 1 7 and the temperature sensor 2 8 to move up and down, which is convenient for temperature detection of lactic acid bacteria liquid at different upper and lower parts. The two ends of the moving plate 6 are fixedly connected with the temperature sensor 1 7 and the temperature sensor 2 8. The temperature sensor 17 is located at the center of the fermentation tank 1, and the temperature sensor 28 is located at the edge of the fermentation tank 1. Through the coordinated use of the temperature sensor 17 and the temperature sensor 28, the temperature sensor 17 can check the temperature inside, and the temperature sensor 28 can detect the temperature outside, so that the temperature detection result is more real and accurate. The top of the temperature sensor 17 is provided with a display terminal 171, and the top of the temperature sensor 28 is provided with a display terminal 281. The display terminal 171 and the display terminal 281 are both fixed on the top of the tank cover 2. By setting the display terminal 171 and the display terminal 281, the display terminal 171 is used to display the temperature detected by the temperature sensor 17, and the display terminal 281 is used to display the temperature detected by the temperature sensor 28, so that the temperature inside and outside of the lactic acid bacteria liquid can be displayed intuitively.

[0023] See also Figures 4 to 5 The outside of the movable plate 6 is fixedly connected with a heat exchange chamber 9, and the heat exchange chamber 9 is a C-shaped structure. The tops of the two ends of the heat exchange chamber 9 are fixedly connected with a feed port 10 and a discharge port 11. By setting the heat exchange chamber 9, the heat exchange chamber 9 is used to heat up or cool down the inside of the lactic acid bacteria liquid. The heat exchange chamber 9 can move up and down, and can more accurately heat up or cool down various parts of the lactic acid bacteria liquid, and more accurately control the temperature of the lactic acid bacteria. The feed port 10 and the discharge port 11 are fixed on the tank cover 2, and the heat exchange chamber 9 and the feed port 10 and the discharge port 11 are connected by a corrugated telescopic tube. The bottom of the tank cover 2 is fixedly connected with a guide rod 12, and the guide rod 12 is movably sleeved inside the movable plate 6. By setting the guide rod 12, the guide rod 12 plays a guiding role, so that the movable plate 6 can move up and down stably to prevent the movable plate 6 from rotating.

[0024] See also Figure 1 , Figure 2 An outer coil 13 is installed in the inner wall of the fermentation tank 1. The outer coil 13 is spirally distributed inside the fermentation tank 1. By setting the outer coil 13, the outer coil 13 can heat up or cool down the lactic acid bacteria liquid from the outside, thereby improving the heating or cooling efficiency.

When the temperature of the lactic acid bacteria liquid is too low or too high, the heat exchange chamber 9 and the outer coil 13 are respectively transported to heat exchange chamber 9 and outer coil 13 to heat or cool the inside and outside of the lactic acid bacteria liquid. At the same time, the heat exchange chamber 9 can move up and down with the movable plate 6, so that each part of the lactic acid bacteria liquid can be heated or cooled more accurately, and the temperature of the lactic acid bacteria can be more accurately controlled.
