In 1799-1801 he was first to developed a technology for obtaining sugar from beets under industrial conditions in Russia.[1] CommercializationIn November 1802, J.S. Esipov built the first beet sugar and alcohol distillery in Russia, in partnership with Yegor Ivanovich Blankennagel in the village of Alyabyevo ({{lang-ru|Алябьево}}) of the Chernovsky County ({{lang-ru|Чернский уезд}}) of the Tula Governorate ({{lang-ru|Тульская губерния}}). During 1802-1803 the factory produced 4.9 tons of raw sugar from beets harvested from 11 tithe of crops (1 tithe = 1.09 ha). The purity of raw sugar was approximately 85%. Waste sugar production (molasses, etc.) was processed into ethyl alcohol. In 1807, the sugar-refining department was added to operation at the plant. For the first time in Russia J.S. Esipov introduced the purification of beet juice with lime. This method is still used at present time.[2][3] Fall of 1802 J.S. Esipov built the second, more advanced beet sugar plant with a sugar refining capabilities in the village of Nikolskoe ({{lang-ru|Никольское}}). In 1803-1804, it produced not only raw sugar, but also white sugar, alcohol, and liquor. The byproduct of manufacturing was used for animal feed. According to calculations by Mr. Esipov, the yield of raw sugar from beet was 3.1% of the beet mass.[4] References1. ^"Есипов Яков Степанович" {{Authority control}}2. ^[https://slovar.wikireading.ru/2456463 "slovar.wikireading"] 3. ^"History of sugar production" 4. ^"History of sugar production" 3 : 1805 deaths|Russian inventors|Russian businesspeople |
