Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0020] Appendix Figure 1 This invention demonstrates the composition and pipe connections of the supply system for hot and cold milk, milk foam, and milk cap. The fresh milk container placed in the system's cold storage compartment or external cold storage compartment is connected to the first three-way connector via a milk valve. The hot water boiler or external hot water source is also connected to the first three-way connector via a cleaning hot water valve. The third interface of the first three-way connector is connected to the second three-way connector via a milk pump.
[0021] It has a steam boiler, and a steam valve, a third tee joint, a check valve and a fourth tee joint are sequentially installed on the pipeline connecting the steam outlet of the steam boiler to the second tee joint.
[0022] The third tee connector is not connected to the third interface on the pipeline between the steam boiler and the second tee connector. It is connected to the air inlet via an air pump, and the flow rate of the air pump is adjustable.
[0023] The fourth three-way connector is not connected to the third interface on the pipeline between the steam boiler and the second three-way connector. It is connected to the cold water inlet via the cleaning cold water valve and the cold water pump. The outlet of the cold water pump is also connected to the water inlet of the steam boiler.
[0024] The third port of the second three-way connector is connected to the reversing valve via the milk frother, and then the reversing valve is used to switch the flow to the milk outlet or to the cleaning residue outlet.
[0025] The supply system has an electrical control device, and a milk valve, a hot water cleaning valve, a milk pump, a milk frother, a reversing valve, a steam valve, an air pump, a cold water cleaning valve, and a cold water pump are electrically connected to the electrical control device.
[0026] A sensor is installed outside the pipe that connects the third interface of the second three-way connector to the milk frother to detect whether there is milk in the pipe. The sensor is electrically connected to the electronic control device.
[0027] The milk valve uses an electromagnetic clamp valve, the milk pump uses a magnetic gear pump, the air pump uses a piston air pump, and the cold water pump uses an electromagnetic pump; the hot water cleaning valve, steam valve, and cold water cleaning valve are all two-position two-way electromagnetic valves, and the directional valve is a two-position three-way electromagnetic valve.
[0028] The usage of this utility model is as follows:
[0029] When using this system, it is best to use high-fat fresh milk to make milk foam. There can be various types of fresh milk in the refrigerator. Of course, high-fat fresh milk can also be used for milk and milk foam. The system's milk extraction tube extends into the fresh milk container.
[0030] First, the use of this system includes the process of making milk products and the cleaning process before and after making milk products. When the system is working, the hot water valve and the cold water valve are closed, and the reversing valve opens the milk product outlet. When the system is cleaning, the hot water valve or the cold water valve and the steam valve are opened, and the reversing valve opens the cleaning residue outlet.
[0031] 1. Making hot milk foam: Hot milk foam is produced by fresh milk, steam and a large amount of air. Fresh milk pumped out by milk pump, steam from steam boiler and a large amount of air pumped out by air pump are mixed at the second three-way connector. The mixture is then frothed into hot milk foam by milk frother.
[0032] II. Cold milk foam making: Cold milk foam is produced by fresh milk and a large amount of air. The steam valve is closed, and the fresh milk pumped out by the milk pump and the large amount of air pumped out by the air pump are mixed at the second three-way connector. The mixture is then frothed into cold milk foam by the milk frother.
[0033] 3. Making hot milk foam involves using fresh milk, steam, and a small amount of air to create hot milk foam. Compared to making hot milk foam, the only difference is that the amount of air pumped in is reduced.
[0034] IV. Cold milk foam making: This involves creating a cold milk foam by mixing fresh milk with a small amount of air. Compared to cold milk foam making, it simply reduces the amount of air pumped in.
[0035] V. Making hot and cold milk: Without introducing air, adding steam will produce hot milk, and not adding steam will produce cold milk; when no air enters the pipes, the milk frother will not create milk foam or a milk topping.
[0036] 6. Hot water cleaning: If the system has not been used for a long time, such as more than 2 hours, open the hot water valve and use hot water to rinse it. This cleaning includes cleaning the milk pump.
[0037] 7. Warm water cleaning: If the system has not been used for a short period of time, such as more than 10 minutes, open the cold water cleaning valve and steam valve. The steam and cold water will combine to form warm water for rinsing. This cleaning does not include cleaning the milk pump. After cleaning, you can use the air pump to dry it.
[0038] The variation between large and small amounts of air produced by milk foam and milk topping is achieved by adjusting the air output of the air pump.
[0039] The sensor's function is to activate the milk frother only when it detects milk flowing through the pipeline. When the system enters the cleaning mode, the sensor signal is blocked, and the milk frother will work during both milk frothing and cleaning.
[0040] This system can exist as a standalone machine or be attached to the inside of a beverage machine. When it exists as a standalone machine, it needs to be equipped with a small refrigerator for storing fresh milk and a hot water boiler. The heating element in the hot water boiler is electrically connected to the electrical control device.
[0041] The production of the aforementioned dairy products is accomplished through the mode selection and corresponding program execution of the electronic control device.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
