Mazzei's Unique Wine Pump-over Aeration Improves Fermentation

Winemakers everywhere are discovering that pumping the juice through a Mazzei^® Venturi injector during fermentation aspirates a substantial amount of air/oxygen into the liquid. This unique process speeds fermentation while aiding in strong yeast development and enhancing the average cell viability. Wine Pump-over Aeration can also minimize the production of sulfides and purge excess carbon dioxide from the top of the tank. Color stabilization of the juice can also be achieved.

Trouble-free with no moving parts, Mazzei Venturi injectors deliver uniform distribution. They are simple-to-use, self-priming and can run dry without problems. Superior mixing is due to Mazzei superior engineering designs.

Cast Stainless Steel Venturi Injectors for Wine Pump-overs

Made of CF3M cast stainless steel, our model 2081 Venturi injector is a complementary product to model 316LSS, a machined product. The cast stainless steel product is a low cost equivalent which still offers vintners all of the high performance and quality they expect in a Mazzei product.

The 2081 Venturi injector was designed not only to provide the fastest and easiest method for aeration, but also to be installed and maintained easily. The 2081 Venturi injector has tri-clamp fittings at all openings for easy installation. The installation can occur at the top of the fermentation tank or at the pump discharge. The cast stainless steel material resists corrosion and is easy to clean.

Mazzei also manufacturers a complete line of Venturi injectors for the wine pump-over market that includes natural PVDF or ECTFE (NSF-51 and FDA 177.2510 approved thermoplastics) in various sizes and corresponding suction capabilities. For more information contact us at 661.363.6500.
