Technical Field
[0001] This utility model relates to the field of milk sterilization technology, specifically to an automatic milk sterilization machine. Background Technology
[0002] A milk sterilizer is a device specifically designed to sterilize milk. Its main purpose is to kill all harmful microorganisms, including pathogens, that may be present in milk to ensure its safety. Most milk sterilizers use pasteurization, a method that kills most pathogens by heating milk to 62-65°C and holding it there for 30 minutes, while preserving more nutrients and flavor. With the continuous development of milk sterilizers, various types of milk sterilizers have emerged, such as an automatic milk sterilizer.
[0003] Currently, milk sterilizers on the market mainly focus on improvements in sterilization. Existing milk sterilizers generally consist of a protective shell, an insulation layer, a water storage and heating layer, an electric heating element, a stirrer, and a controller. Fresh milk is poured into the protective shell, and the electric heating element heats the stored water, thus sterilizing the milk. The stirrer then agitates the fresh milk to ensure even heating. However, existing pasteurized milk sterilizers require manual addition of milk and dispensing via a tap, which is inconvenient and cannot provide continuous automatic sterilization. Therefore, an automatic milk sterilizer that can continuously sterilize, is easy to operate, and requires no manual supervision is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic milk sterilizer, which has the advantages of being able to set the milk sterilization capacity, automatically and continuously sterilizing, being easy to operate, and requiring no manual supervision. It solves the problem that existing pasteurized milk sterilizers require manual addition of milk and dispensing of milk through a tap, which is cumbersome and cannot continuously and automatically sterilize.
[0005] To achieve the above-mentioned purpose of being able to set the milk sterilization capacity, automatically and continuously sterilize, and being simple to operate without human supervision, this utility model provides the following technical solution: an automatic milk sterilizer, including a protective shell, a feed pipe fixedly installed on the top of the protective shell, and a sterilization mechanism provided inside the protective shell;
[0006] The disinfection mechanism includes an insulation layer, a water storage tank, electric heating tubes, an outer electronic water level gauge, an electrically controlled valve one, a heating tank, a discharge pipe, and an electrically controlled valve two. The protective shell has an insulation layer inside, a water storage tank inside, four electric heating tubes fixedly installed inside, an outer electronic water level gauge fixedly installed inside, an electrically controlled valve one fixedly installed outside, a heating tank fixedly installed inside, a discharge pipe fixedly installed at the bottom of the heating tank, and an electrically controlled valve two installed outside the discharge pipe.
[0007] Furthermore, a water inlet pipe is fixedly installed on the outside of the protective shell, the water inlet pipe is connected to the water storage tank, and an electrically controlled valve is installed on the outside of the water inlet pipe.
[0008] Furthermore, a motor is fixedly installed on the top of the protective shell, and the output end of the motor is provided with stirring blades, the number of which is two.
[0009] Furthermore, a controller is fixedly installed on the outside of the protective shell, and a timer is installed inside the controller.
[0010] Furthermore, the heating tank is equipped with an inner electronic water level gauge and a temperature sensor.
[0011] Furthermore, the bottom of the heating tank is provided with an arc surface, which allows the sterilized milk to flow downwards into the discharge pipe.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] This automatic milk sterilization machine, through its sterilization mechanism, connects the feed pipe to the fresh milk tank when sterilization is required. The controller automatically opens the first electrically controlled valve according to a pre-set program. After the inner electronic water level gauge reaches the designated height, the first electrically controlled valve closes. Then, the electric heating element is turned on to heat the milk, and the motor is turned on to agitate the milk. Once the temperature sensor detects that the milk has reached the designated temperature, pasteurization is performed. Subsequently, the second electrically controlled valve is opened, and the finished milk is discharged through the discharge pipe. The controller then repeats the above steps to continuously sterilize the milk. This sterilization mechanism can automatically and continuously sterilize, is simple to operate, and requires no manual supervision. Attached Figure Description
