The technologies used to make condensed milk and evaporated milk were applied in the early twentieth century to the production of dried milk powder.
Nicholas Appert, produced dried tablets in 1810. A patent for a dried milk process with sugar added was issued to a man name Birdeye in 1850 and in 1855 a British patent covering a milk drying process with issued to Grimwade and a number of other patent were issued.
In 1869, Henry Nestle perfected the process in Switzerland.
United States issued a patent for producing it in 1872. In 1899, Dr. Martin Eckenberg, of Sweden, developed a film drier operating in a vacuum.
In United Kingdom, sterile powder milk successfully marketed after 1900, when new technological process permitted large-scale manufacturing, it was first bought by a managerial, professional and artisanal segments of British society.
By 1907, the local milk stations began to distribute it in place of liquid milk, so that its use spread to the poorer workers.
In United States in 1895, candymaker Milton Hershey crated milk chocolate formula based on Swiss method of combining conched chocolate with powdered milk.
Whole and skim milk powders are commercially produced currently by spray-drying. Whole or skim milk is dispersed as fine droplets into stream of hot air and the bulk of the water evaporates in a matter of second.
By 1980s imported dried milk became a significant competitor in developing countries for people who lacked refrigeration.
