Enjoy Your Coffee Life How does a milk frother work? Frothing milk involves a process that introduces air into the chemical properties of milk to create the light and airy product of frothed or foamed milk. The pros of automatic milk forther compared with handheld one 1. The automatic frother will froth cold or warm milk for your coffee and milk beverages at the touch of a button. 2. Equipped with a strix temp control, automatic milk forther will auto shut off when the milk is at desired temperature when frothing. (Needn’t to heat milk before forthing) 3. Automatic frothers run on electricity and provide a hands-free operation. Warm Foam Use the thick warm foam setting to crown a cappuccino or a perfect latte. Cold Foam Enter cold foam: foam that's frothed without the use of heat or steam. The result is a thick and creamy meringue-like topping that's ideal for layering over the top of iced cold brew, nitro coffee, and iced lattes. Multifunctional Frother Whole milk is recommended (Fat content>3%) The SCA recommends heating milk to 139–149°F(55–65°C ) with a maximum temperature of 158°F(70°C ) and minimum of 122°F(50°C). At this temperature, the amount of whey protein denaturation is ideal for the best adsorption on the surface of air bubbles, so your foam will be stable. While frothing, make sure to pour the milk to the max line(not the top but the lower one), to avoid overflowing. Use a whisk without a spring to heat milk.
