Air is introduced from the steam wand by immersing only the tip of the wand in the milk. This process is sometimes known as frothing, stretching, or surfing, [8] and usually lasts less than 10 seconds. After the creation of small bubbles, the milk is covered with a soft foam phase which separates from the liquid and floats on top of the milk.
A milk frother is a utensil for making milk froth, typically to be added to coffee (cappuccino, latte, etc.). It aerates the milk, creating a thick but light foam. [ 1 ] Milk frothers were introduced through the use of espresso machines that contained steamed wands that would froth steamed milk.
Foam fractionation is a chemical process in which hydrophobic molecules are preferentially separated from a liquid solution using rising columns of foam. It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums ; these units are known as " protein skimmers ".
An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...

Changing whole milk to butter is a process of transforming a fat-in-water emulsion to a water-in-fat emulsion . Whole milk is a dilute emulsion of tiny fat globules surrounded by lipoprotein membranes that keep the fat globules separate from one another. Butter is made from cream that has been separated from whole milk and then cooled; fat ...
Warm milk skimming separator: At first the raw milk is heated and then skimmed warm. There is a significant difference in density between cream and skimmed milk, because of the higher temperature. Cold milk skimming separator: Because of the lower energy, which is used, the production cost will be reduced. Also at cold temperatures, the growth ...
