Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a liquid milk fermentation and cooling device, including a fermenter 1, an inner cavity of the fermenter 1 is provided with a wall cavity, and an external cooling mechanism 9 is arranged in the wall cavity. An internal cooling mechanism 10 is arranged in the inner cavity of the fermenter 1. A detachable tank cover 2 is arranged above the fermenter 1. A stirring mechanism 8 for stirring dairy products is installed on the tank cover 2. The stirring mechanism 8 and the internal cooling mechanism 10 are arranged alternately;

[0023] The internal cooling mechanism 10 includes a first coil 102 and a second coil 104. The upper end of the first coil 102 penetrates through the tank cover 2 and is communicated with a shunt pipe 101. The lower ends of the second coil 104 and the first coil 102 are both communicated with a ring pipe 103. The inner diameter of the ring pipe 103 is smaller than the inner diameter of the fermenter 1. The first coil 102 and the second coil 104 are both arranged in a snake shape. The first coil 102 and the second coil 104 are symmetrically arranged. Second valves 105 are arranged at the water outlet end of the second coil 104 and the water inlet end of the shunt pipe 101.

[0024] The stirring mechanism 8 includes a motor 81 and a rotating main shaft 82. The motor 81 is installed on the upper surface of the tank cover 2. The upper end of the rotating main shaft 82 penetrates through the tank cover 2 and is driven by the motor 81. Two groups of stirring inner rods 83 are symmetrically welded to the outside of the rotating main shaft 82. Two groups of scraping wall bottom rods 84 are welded to the lower end of the rotating main shaft 82. Two groups of stirring outer rods 85 are welded to the opposite sides of the two groups of scraping wall bottom rods 84. By driving the main shaft to rotate through the motor 81, the rotating main shaft 82 drives the stirring inner rods 83 and the scraping wall bottom rods 84 to rotate. The scraping wall bottom rods 84 drive the stirring outer rods 85 to stir the dairy products synchronously, improving the stirring range, thereby improving the uniformity of stirring the dairy products and accelerating the cooling efficiency of the dairy products.

[0025] The stirring inner rods 83 and the two groups of stirring outer rods 85 are both arranged in the same plane, and the two groups of stirring inner rods 83 and the two groups of stirring outer rods 85 are arranged alternately. The stirring inner rods 83 and the stirring outer rods 85 stir between the first coil pipe 102 and the second coil pipe 104, thereby improving the stirring effect on the dairy products, further accelerating the cooling efficiency of the dairy products, and preventing the dairy products from generating precipitates.

[0026] The external cooling mechanism 9 includes a cooling coil pipe 92 arranged in the wall cavity. The water inlet end of the cooling coil pipe 92 is communicated with a water inlet pipe 91, and the water outlet end of the cooling coil pipe 92 is communicated with a water outlet pipe 93. First valves 94 are arranged at one ends of the water inlet pipe 91 and the water outlet pipe 93. By connecting to an external water supply device at the water inlet end, the recycling of cooling water is realized. At the same time, under the action of the shunt pipe 101, the internal and external cooling of the dairy products is synchronized, improving the cooling efficiency.

[0027] A temperature equalizing plate 12 wrapping the cooling coil pipe 92 is arranged in the wall cavity of the fermentation tank 1. The cooling coil pipe 92 is arranged in a spiral shape, and better temperature conduction can be carried out through the temperature equalizing plate 12.

[0028] A feeding pipe 7 is arranged on the upper surface of the fermentation tank 1. A pressure gauge 3 for detecting the internal pressure of the fermentation tank 1 is arranged on the upper surface of the fermentation tank 1. A thermometer 4 for monitoring the temperature inside the fermentation tank 1 is arranged on the outside of the fermentation tank 1. It is convenient to detect the pressure inside the fermentation tank 1 through the pressure gauge 3, and at the same time, the cooling temperature of the dairy products inside the fermentation tank 1 is displayed by using the thermometer 4, so as to facilitate the discharge of the dairy products after cooling is completed.

[0029] An observation window 5 is arranged on the outside of the fermentation tank 1. A moving support 6 is fixedly connected to the lower end of the outside of the fermentation tank 1. A discharge pipe 11 is arranged on the lower surface of the fermentation tank 1. It is convenient to move the fermentation tank 1 by using the moving support 6, thereby improving the overall convenience of the device.

[0030] In use, it is convenient to put dairy products through the feeding pipe 7, and a cover body for sealing is arranged on the feeding pipe 7. When the dairy products need to be cooled after fermentation in the fermentation tank 1 is completed, the first valve 94 and the second valve 105 of the external cooling mechanism 9 and the internal cooling mechanism 10 are opened, and cooling water is introduced through the water inlet pipe 91. The cooling water is split into the first coiled pipe 102 through the shunt pipe 101, and the water in the first coiled pipe 102 flows into the second coiled pipe 104 through the annular pipe 103. At the same time, the cooling water is discharged through the water outlet pipe 93 by the cooling coiled pipe 92. The cooling water exchanges heat with the dairy products during the flowing process, and at the same time completes the heat exchange in the middle and outside of the fermentation tank 1, thereby improving the cooling efficiency of the hot products, further shortening the cooling time of the dairy products, and thus improving the production efficiency of the dairy products.
