Various technical innovations were actively used in Sarepta, a German colony. The Sareptians did not miss the opportunity to facilitate domestic using new devices. The milk separator has made the process of separating milk into its constituent parts less labor intensive. Thanks to the separator, housewives spent less time and effort on obtaining cream for making butter.

Despite the asceticism of the Sarepta Hernguters - representatives of Protestantism - they were not forbidden to consume milk, butter, cream during fasting. Butter was one of the daily staples of the inhabitants of Sarepta. This is how the journalist Alexander Voeikov, who lived in the settlement in 1812-1813, described the food of the Sareptians:

The Sareptians prepared many dishes from milk. Homemade and processed cheese and cottage cheese were made from fermented milk. The fresh milk was filtered and put into the cellar. From the skimmed sour cream and sour cream, butter was churned in churns. Cream and milk were added to coffee and tea.

The History of Sarepta exhibition presents the Westfalia manual milk separator, which was restored by the museum staff. The separator is based on centrifugal force. Milk is poured into a special drum, the rotation of which generates centrifugal force. Due to the difference in the masses of the constituent parts of the milk is divided into cream and a fat-free part – skim milk. The skim milk and cream streams are discharged into specially prepared containers. The first manual separators were not equipped with self-emptying drums - residues were removed from them manually.

The first separator based on centrifugal force was invented by the Swedish engineer Gustav de Laval in 1878. And in 1893, stepbrothers Franz Ramezol and Franz Schmidt opened the Westfalia workshop in Elda, Westphalia, and began to produce milk separators. By 1900, more than 10,000 milk separators from this company were in operation. They were reliable and easy to use.
