Our History

Alfredo Melandri and Luigi Deggiovanni, before agricultural machinery producers on behalf of third parties, started designing and producing two screws continuous presses and vertical hydraulic presses for grape pressing.
Then Costruzioni Meccaniche Deggiovanni & Melandri company was established.


The company extended its production of machinery for the wine-making field. The first Florsvin-Enotork unit for grape continuous pressing, “Velocipressa” and press for distillery were worked out. The products were sold to the main Italian wineries and abroad in the main foreign countries producing wine.
Costruzioni Enolmeccaniche DIEMME s.n.c. company was established from Deggiovanni & Melandri and moved to Lugo (RA), Via Bedazzo.


The new company lived a great growth in the wine-making field. The Florsvin Enotork 780 – 670 – 600 continuous lines range was extended and it met with the general approval. More equipment for wine-making process in the filtration, thermo-vinification, flotation and destemming field were worked out.

In 1986 Costruzioni Enolmeccaniche DIEMME s.n.c. and Filtri Diemme SpA companies merged in only one company named DIEMME SpA and the logo, that will come with us till the 100th anniversay, was developped. Two independent branches of business were born, Winemaking Division and Filtration Division, which developed respectively their business with new technologies and markets.
