[0002] Milk is loved by people because it is rich in nutrients, but it is also easy to spoil and difficult to store. Due to geographical issues in China, all companies use UHT sterilization technology to sterilize milk in order to achieve the purpose of long-distance transportation. UHT is the abbreviation of ultra-high temperature sterilization. That is, using a high temperature of 134℃~135℃ to instantly sterilize raw milk for 4 seconds, so that all harmful bacteria and microorganisms in the milk, including their spores, are killed.

[0003] After searching, the Chinese patent publication number CN208875281U discloses an automated milk sterilization device, including a box layer, a heat preservation layer is arranged inside the box layer, a motor is installed at the upper end of the box layer, a rotating shaft is connected to the lower end of the motor, a feed port is arranged on the left side of the box layer, an ultraviolet light switch is installed on the right side of the box layer, a heating rod is installed inside the box layer, a heating rod connecting device is arranged on the right side of the heating rod, a filter is arranged at the lower end of the heating rod, a waste chip port is arranged outside the box layer, and a pull ring is installed on the left side of the waste chip port, a nozzle is installed on the front of the box layer, a support frame is installed on the right side of the box layer, and a main control box is installed on the upper end of the support frame, a supporting leg is installed at the bottom end of the box layer, screws are arranged outside the heating rod connecting device, and an ultraviolet light switch housing is installed outside the ultraviolet light switch.

[0030] The switching assembly includes a ratchet 13 and a claw 14, the ratchet 13 is fixed to the outer wall of the stirring shaft 7, the claw 14 is rotatably connected to the inner wall of the top end of the rotating cylinder 11, one end of the claw 14 is limitedly matched with the ratchet 13, a limiting column 16 is provided on one side of the claw 14, and a limiting spring 15 is fixed to the outer wall of the other side of the claw 14, and the other end of the limiting spring 15 is connected to the inner wall of the rotating cylinder 11.

[0031] During the sterilization process, the motor 6 drives the stirring shaft 7 to rotate to stir the milk. At this time, the ratchet 13 rotates with the stirring shaft 7, squeezing the claw 14, and the limit spring 15 is compressed, so that the claw 14 avoids the ratchet 13, so that the rotating cylinder 11 cannot rotate with the stirring shaft 7. When the milk is sterilized and discharged from the discharge port 3, the motor 6 reverses. At this time, the claw 14 cannot rotate to one side due to the limitation of the limit column 16, so that the stirring shaft 7 drives the rotating cylinder 11 to rotate through the ratchet 13, so that the cleaning plate 9 scrapes and cleans the inside of the box body 1. At the same time, during the rotation process, the sleeve 10 continuously slides back and forth along the rotating cylinder 11 through the cooperation of the fixed column 12, the U-shaped groove and the reset spring 17, so that the cleaning plate 9 and the inside of the box body 1 are displaced up and down, so that the cleaning effect is better.

When the milk is sterilized and discharged from the discharge port 3, the motor 6 reverses. At this time, the claw 14 cannot rotate to one side due to the limitation of the limit column 16, so that the stirring shaft 7 drives the rotating drum 11 to rotate through the ratchet 13, thereby reducing unnecessary friction between the cleaning plate 9 and the inner wall of the box body 1, and improving the service life of the cleaning plate 9.

[0034] Example 2

[0035] Normal temperature milk sterilizing machine, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 5 As shown, the side wall of the connecting frame 8 is provided with a slide groove 18, one end of the cleaning plate 9 is slidably matched with the slide groove 18, a connecting block 19 is provided on one side of the slide groove 18, the connecting block 19 is slidably matched with the connecting frame 8, a return spring 22 is fixed to one end of the connecting block 19, a limiting hole that is limited and matched with the connecting block 19 is provided on the outer wall of one side of the cleaning plate 9, an extrusion rod 21 is provided on one side of the connecting block 19, and an inclined groove that is slidably matched with the extrusion rod 21 is provided on the side wall of the connecting block 19, and a return spring 22 is connected to one side of the extrusion rod 21.

[0036] When replacing the cleaning plate 9, push the extrusion rod 21 to squeeze the chute, so that the connecting block 19 moves to one side and disengages from the cleaning plate 9, then pull the cleaning plate 9 out of the chute 18, and insert a new connecting block 19.

[0037] By setting the slide groove 18, the connecting block 19, the connecting spring 20, the squeezing rod 21 and the reset spring 22, when replacing the cleaning plate 9, the squeezing rod 21 is pushed to squeeze the inclined groove, so that the connecting block 19 moves to one side and disengages from the cleaning plate 9, and then the cleaning plate 9 is pulled out of the slide groove 18 and the new connecting block 19 is inserted, so as to facilitate the replacement of the cleaning plate 9.

[0038] Working principle: during the sterilization process, the motor 6 drives the stirring shaft 7 to rotate and stir the milk. At this time, the ratchet 13 rotates with the stirring shaft 7, squeezing the claw 14, and the limit spring 15 is compressed, so that the claw 14 avoids the ratchet 13, so that the rotating cylinder 11 cannot rotate with the stirring shaft 7. When the milk is sterilized and discharged from the discharge port 3, the motor 6 reverses. At this time, the claw 14 cannot rotate to one side due to the limit of the limit column 16, so that the stirring shaft 7 drives the rotating cylinder 11 to rotate through the ratchet 13, so that the cleaning plate 9 scrapes and cleans the inside of the box body 1. At the same time, during the rotation process, the sleeve 10 continuously slides back and forth along the rotating cylinder 11 through the cooperation of the fixed column 12, the U-shaped groove and the return spring 17, so that the cleaning plate 9 and the inside of the box body 1 are displaced up and down, so that the cleaning effect is better; when replacing the cleaning plate 9, push the extrusion rod 21 to squeeze the chute, so that the connecting block 19 moves to one side and disengages from the cleaning plate 9, then pull the cleaning plate 9 out of the slide groove 18, and insert the new connecting block 19.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
