Fábrica de harinas San Antonio in Medina de Rioseco

In the heart of Medina de Rioseco, Valladolid, the Fábrica de harinas San Antonio is an industrial building dating from 1852. It is located at the first water drop of the Canal de Castilla. The factory's development followed the completion of the canal in 1849 and the arrival of the railway in Valladolid in 1864. Over time, stone mills were replaced with cilindros estriados, and a 1912 reform introduced modern machinery for cleaning and milling.

In 1914, there was a strong increase in flour exports. The current production system was established in 1944, based on a layout designed for Antonio de Hoyos to automatically mill 17,000 kilos of soft wheat in 24 hours. While the factory closed production a few years ago, it is now owned by the Town Hall of Medina de Rioseco.

Most of the machinery preserved inside is from 1944, which serves as the main attraction of the factory. The machinery includes brands such as Daverio, Robinson, Buhler, Morros, Gombar, Henri Simon, and Pérez y Montané, complemented by Siemens motors. The factory produced flour, tercerilla, cuarta, and salvado de hoja.
