Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of design of foaming milk foam preparation devices, in particular to a foaming device for steam foaming milk foam. Background Art
[0002] Frothed milk not only adds visual and flavorful appeal to coffee and other hot drinks, but also offers several practical benefits. First, milk foam offers a unique taste experience. Its dense and silky texture contrasts with the bitterness of coffee, adding richness and balance to the drink. This contrast not only satisfies the taste buds but also adds a layer of depth to the drink. Second, frothed milk foam retains heat to a certain extent, keeping hot drinks warm longer—a significant advantage for those who enjoy savoring their coffee more slowly. Furthermore, the foamy structure of milk foam can buffer the direct impact of caffeine, resulting in a gentler release and less stomach irritation. Furthermore, the milk foaming process heats and beats the lactose and proteins in milk, which helps enhance the milk's flavor, making it sweeter and more fragrant. For those with lactose intolerance, a moderate amount of milk foam can enhance the milk's flavor while reducing lactose intake.
[0003] The existing foaming device for foaming milk foam often requires a long waiting time during the foaming process, the heating area of the milk foam is small, and the discharge speed is slow. Utility Model Content

[0023] See also Figures 1-4 A steam-frothing milk foaming device comprises a mixing device 1 , on the top of which a steam heating device 2 is provided.
[0024] In this embodiment, the mixing device 1 includes a connecting valve 101, a milk solenoid valve 103 is provided at the top of the connecting valve 101, a milk inlet pipe 104 is provided on the outside of the milk solenoid valve 103, a mixing core assembly 105 is provided on one side of the connecting valve 101, a high-frequency air valve 102 is provided at the bottom of the mixing core assembly 105, a gear pump 106 is provided on one side of the mixing core assembly 105, and a transfer pipe 107 is provided at the output end of the gear pump 106. A control panel 3 is provided in front of the mixing device 1, and a fixing frame 4 is provided on one side of the control panel 3. The output end of 05 is connected to the input end of the gear pump 106. When the milk solenoid valve 103 is open, the milk flows along the milk inlet pipe 104 through the connecting valve 101 and enters the mixing core assembly 105. At the same time, the high-frequency air valve 102 draws air and injects it into the mixing core assembly 105. In this process, the milk and air are mixed to form dense milk foam. The degree of density of the milk foam can be controlled by adjusting the air flow of the high-frequency air valve 102. This is pre-mixing. The pre-mixed milk foam is further mixed by the gears in the gear pump 106 and then flows into the heated pipe 201 through the transfer pipe 107.
[0025] In this embodiment, the steam heating device 2 includes a heating pipe 201, a stainless steel coil 202 is provided on the outside of the heating pipe 201, a steam joint 203 is provided on the top of the stainless steel coil 202, a steam solenoid valve 207 is provided on the bottom of the steam joint 203, a steam inlet pipe 204 is provided on the outside of the steam solenoid valve 207, a discharge pipe 205 is provided on the top of the heating pipe 201, a nipple 206 is provided at the end of the discharge pipe 205, a transfer pipe 107 is connected to the heating pipe 201, the heating pipe 201 is located in the center of the stainless steel coil 202, the heating pipe 201 and the stainless steel coil 202 are both spirally evenly arranged, the steam inlet pipe 204 is connected to the heat source that generates steam, the milk foam in the transfer pipe 107 rises spirally along the heating pipe 201, and the steam solenoid valve 207 is provided at the bottom of the steam joint 203. 7. The steam inlet pipe 204 is controlled to transport steam through the steam connector 203 and into the stainless steel coil 202. The steam spirally moving along the stainless steel coil 202 heats the milk foam in the heating tube 201 in the middle of the stainless steel coil 202, causing the milk foam to reach a set temperature. Finally, the steam flows along the discharge pipe 205 at the top of the heating tube 201 and enters the nipple 206. The nipple 206 guides the foamed milk foam to fall and complete the discharge. By arranging the spiral stainless steel coil 202 to wrap around the heating tube 201, the mixed milk foam is fully heated. The spiral heating tube 201 can increase the heating area of the milk foam, so that the milk foam is heated to the required temperature during the movement, which facilitates the discharge speed. At the same time, the steam can better release heat, resulting in lower overall energy consumption and higher economic efficiency of the device.
[0026] Working principle: The device is fixed in the coffee machine through the fixing frame 4, and the steam inlet pipe 204 is connected to the heat source that generates steam. When working, the milk solenoid valve 103 is opened, and the milk passes through the connecting valve 101 along the milk inlet pipe 104 and enters the mixing core assembly 105. At the same time, the high-frequency air valve 102 extracts air and injects it into the mixing core assembly 105. In this process, the milk and air are mixed to form dense milk foam. The degree of milk foam density can be controlled by adjusting the air flow of the high-frequency air valve 102. This is pre-mixing. The pre-mixed milk foam is then mixed again by the gear stirring in the gear pump 106 and flows into the heated pipe 201 through the transfer pipe 107. The milk foam in the transfer pipe 107 spirally rises along the heated pipe 201. At the same time, the steam solenoid valve 207 controls the steam inlet pipe 20 The steam is conveyed through the steam connector 203 and enters the stainless steel coil 202. The steam spirally moves along the stainless steel coil 202, heating the milk foam in the heating tube 201 in the middle of the stainless steel coil 202, so that the milk foam reaches a set temperature. Finally, the steam enters the nipple 206 along the discharge pipe 205 at the top of the heating tube 201. The nipple 206 guides the foamed milk foam to fall and complete the discharge. By arranging the spiral stainless steel coil 202 to wrap the heating tube 201, the mixed milk foam is fully heated. The spiral heating tube 201 can increase the heating area of the milk foam, so that the milk foam is heated to the required temperature during the movement, which is convenient for increasing the discharge speed. At the same time, the steam can better release heat, lowering the overall energy consumption of the device and improving economic efficiency.
