Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation equipment technology, specifically to a constant temperature fermentation device for fermented milk. Background Technology
[0002] After pretreatment, dairy raw materials enter the fermentation tank, where a specific lactic acid bacteria inoculum is added. Under the control of the system, the internal environment (temperature, pH, oxygen concentration, etc.) is precisely controlled. Lactic acid bacteria rapidly multiply in this optimal environment, converting lactose into lactic acid, thus acidifying the milk and producing its unique flavor. Isothermal fermentation refers to maintaining the temperature of the fermentation system within a relatively constant range during the fermentation process. Isothermal fermentation is crucial for fermented milk because it directly affects the growth and metabolism of lactic acid bacteria and the quality of the final product.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0033] Combination Figure 1-4A constant-temperature fermentation device for fermented milk includes a fermentation tank 1. A support column 2 is fixedly connected to the bottom of the fermentation tank 1, ensuring the entire device remains horizontal. An inner liner 20 is fixedly connected inside the fermentation tank 1, and the space between the fermentation tank 1 and the inner liner 20 is filled with heat-insulating material 16, typically polyurethane foam. The interaction between the inner liner 20, the fermentation tank 1, and the heat-insulating material 16 achieves a heat-insulating effect. A lid 5 is installed on the top of the fermentation tank 1. The lid 5 is removable for easy cleaning and is sealed during operation. A pH meter 8 is installed on the top left side of the lid 5, allowing the pH value inside the device to be detected via a pH probe. A motor 6 is installed in the center of the top of the lid 5. The output of the motor 6... One end of the fermentation tank 1 is fixedly connected to a stirrer 14, and the other end of the stirrer 14 is rotatably connected to the middle of the bottom of the inner tank 20. The motor drives the rotation of the stirring rod to achieve a uniform stirring effect. A vortex heating rod 15 is fixedly connected to the inner side of the bottom of the fermentation tank 1. A temperature control device 18 is fixedly connected to the middle of the left side of the fermentation tank 1. The temperature control device 18 controls the temperature of the vortex heating rod 15 to achieve precise temperature control and uniform heating. An air vent 13 is provided on the upper front side of the fermentation tank 1. The air vent 13 passes through and is fixedly connected to the upper front side of the inner tank 20 to exhaust the contents of the device. An outlet 11 is provided on the lower front side of the fermentation tank 1. The outlet 11 passes through and is fixedly connected to the lower front side of the inner tank 20 to remove the product.
[0034] A barometer 7 is installed on the front of the top of the lid 5 to monitor the air pressure inside the device. A feed pipe 17 is fixedly connected through the top of the lid 5. A pump 9 is fixedly connected to one end of the feed pipe 17. A raw material tank 10 is fixedly connected to the bottom of the pump 9. The feed port of the pump 9 passes through the raw material tank 10 through a pipe and extends to the bottom of the raw material tank 10. The feed pipe 17 takes out the raw material from the raw material tank through the pump 9 and puts it into the stirring device. Valves 12 are installed at the top of the discharge port 11 and the air port 13 to control the on and off. A window 19 with glass is opened on the upper left side of the fermentation tank 1 to facilitate the observation of the inside by the staff during the operation. A water level gauge 3 is fixedly connected to the upper right side of the fermentation tank 1 to facilitate the observation of the water level inside.
[0035] Working principle: First, turn on the power supply 4. After determining the fermentation strain, place it in the raw material tank 10. Observe the appropriate amount of water added through the water level gauge 3. Then, open the valve 12 of the air vent 13 to expel air from the stirring device. After turning on the vortex heating rod 15, adjust the temperature control device 18 to a suitable temperature. In this way, the vortex heating rod 15, which is laid flat at the bottom of the device, can evenly heat the device. After preparation, turn on the pump 9 on the raw material tank 10 to transport the raw material into the stirring device through the feed pipe 17. Then, open the motor 6 on the cover 5 to drive the stirring rod to start working. Turn on the pH tester 8 and the barometer 7 to monitor the internal pH value and air pressure value in real time. When the air pressure is too high, the air vent 13 needs to be opened to release the excess carbon dioxide in a sealed manner to prevent the mixing of air and bacteria. During the operation, the fermentation tank 1, the inner liner 20, and the heat insulation material 16 (polyurethane foam) between them can isolate the temperature and play a good role in constant temperature preservation. After fermentation is completed, open the valve 12 and take out the product through the discharge port 11.
