Oil press Valea Mică – Zlatna, Alba county, 19th century
Locally called "Oloiniță", the installation was transferred to the museum in 1967 and consists of four distinct components involved in the same technological process, namely the manufacture of oil seeds.
The hydraulic wheel and the axle with feathers train the hammers that hit the seeds placed in the "pot", pushing them. The flour obtained after the pissing was sifted in the sieve and kneaded with water, the resulting cake being frying on an integrated metal tray. Once fried, the cake was subjected to the pressure of the massive beam of the spike by twisting the wooden screw, the oil flowing into the place dug in the pipe. From 3-4 kg of seeds, about 1 liter of oil was obtained, depending on the quality of the seeds.
The installation is complemented by a crush made up of a rounded stone rolled in a semicircular gutter. The fruits (especially apples) were crushed and inserted into the press, and later, by fermentation, food vinegar.
The complex is sheltered under a chopon with wooden pillars, surrounded by a short stone wall, which support a roof in four waters with shingles (originally from straw).
