Description

Technical Field

[0001] The utility model relates to the technical field of milk production, in particular to a milk production device. Background Art

[0002] Before the milk is produced, it will be sent to the dairy factory. After receiving the raw materials and quality inspection, the milk quality is ensured to meet the requirements. The fresh milk is heat-pasteurized, usually by high temperature short-time treatment or ultra-high temperature treatment, to kill bacteria and extend the shelf life. The heated milk needs to be evenly mixed by a stirring device to ensure that the ingredients are evenly distributed, which can help producers improve production efficiency and ensure milk quality.

[0003] When sterilizing milk, the traditional milk production device first heats the milk to a higher temperature, and then uses a single-chip microcomputer to control the motor to drive the rotating shaft to rotate, which drives the evenly distributed stirring rods to rotate to ensure its uniformity and stability.

[0004] Traditional milk production devices have the following problems: using a single stirring rod may not achieve sufficient sterilization effect during the stirring process, may require a longer stirring time or increase the stirring intensity, and may leave milk or dirt in the unreachable areas, which may easily lead to repeated bacterial growth. For this reason, we propose a milk production device. Utility Model Content

During the heating process, the single-chip microcomputer 5 controls the operation of the motor 21. The rotation of the output shaft of the motor 21 drives the rotating shaft 22 to rotate. However, the rotating shaft 22 is fixed in the rotating groove of the top wall of the mixing barrel 4 through the support of the bearing. The rotation of the rotating shaft 22 drives the scraper 27 to rotate, thereby ensuring that the milk is evenly stirred. At the same time, the scraper 27 contacts the inner wall of the mixing barrel 4 during rotation to avoid milk residue on the inner wall of the mixing barrel.

[0026] The working principle of a milk production device provided by the utility model is as follows: first, the milk is poured into the mixing barrel 4 through the feeding pipe 1, and then the electric heating wire 11 is controlled by the single chip microcomputer 5 to heat it so as to reach an appropriate temperature for sterilization, and exhaust is achieved through the air valve 7 at the top of the exhaust pipe 3 to ensure that the gas inside the milk can be discharged smoothly during the heating process to avoid excessive pressure affecting the treatment effect.

However, the rotating shaft 22 is fixed in the rotating groove of the top wall of the mixing barrel 4 through the support of the bearing. The rotation of the rotating shaft 22 drives the scraper 27 to rotate, thereby ensuring that the milk is evenly stirred. At the same time, the scraper 27 contacts the inner wall of the mixing barrel 4 when rotating to avoid milk residue on the inner wall of the mixing barrel. At the same time, the rotating shaft 22 drives the bevel gear 3 96 to rotate when rotating, and the bevel gear 3 96 rotates. 6 meshes with bevel gear 2 95 and rotates, so that bevel gear 2 95 starts to rotate. Bevel gear 2 95 rotates and meshes with bevel gear 1 92 and rotates, thereby driving bevel gear 1 92 to start rotating. At this time, bevel gear 1 92 rotates in the opposite direction to bevel gear 3 96 through the transmission of bevel gear 2 95, and drives the rotating cylinder 23 to rotate. The rotating cylinder 23 is fixed to the middle part of the rotating shaft 22 through the support of the bearing, and drives the support rod 24 to rotate. The support rod 24 drives the stirring blade 25 to rotate. The rotation of the stirring blade 25 and the scraper 27 form a rotation in the relative direction, which can ensure that the milk is fully stirred, which helps to improve the sterilization effect and make the sterilization more uniform and thorough. However, when the stirring blade 25 rotates, the existence of the avoidance port 26 allows the milk to pass smoothly during rotation, and will not interfere with the stirring of the milk, ensuring the continuity and efficiency of the stirring process. After the sterilization is completed, the valve 81 is opened and the milk flows out to the outside in sequence through the discharge pipe 8.
