Since 2002, the Agricultural Experimental Station INTA Mendoza ASSI SA and the company, are developing vinaria automaceración vessel for the production of red wines, oenological performance multi-ASSI INTA. This development ends with the problems of maceration and allows multiple jobs on a single tank of circular stainless steel. The idea came from the INTA. The automaceración is a practice that has been developed 20 years ago in Europe. This vessel is performed in horizontal position of great space and has no other purpose than the specific. Then came the idea of building a system that meets existing vessels and oenological have other benefits, said agronomist Santiago Sari, Center for Studies Enológicos EEA INTA Mendoza. While described that besides allowing automaceración, INTA ASSI vessel has a device for incorporating oxygen through porous diffusers at the bottom of the vessel, necessary for growth of the yeast during fermentation. It also has a system of gentle pressing of the marc allows quick draining wort flower. Another benefit is that you can add whole grains to make a carbonic maceration then pressing those grains and stick with a traditional fermentation. Recently, this development won first prize in the IV Provincial Technology Innovation Competition 2007, organized by the Institute of Industrial Development, Technological Services and Mendoza (IDITS) held in the context of the 5th edition of 2007. Expometalmecánica the vessel system advantages, and facilitate and make efficient maceration wine, winemaking has complementary benefits; as the incorporation of microporous diffusers for the incorporation of carbon dioxide in the carbonic maceration-fermentation and oxygen during the fermentation process. When the cycle of the wine fermentation and removed, the air cylinder moves down through the telescopic system, enabling the gentle pressing of the marc deposited on the bottom of the equipment. This operation can also be performed in stage before fermentation, such as a carbonic maceration in which can be pressed grape seeds in the same tank, then performing a conventional mashing. The team can include an accessory that allows you to extract the seeds during fermentation. It has a control panel that automates the movement of the rack piston controlling the fermentation temperature and adjust the quantity of oxygen incorporated during alcoholic fermentation. The vessel can also be used for aging wine. They are built in capacities up to 150 Hl. The project has received funding it through a Secyt Fontar credit and adaptive testing of the vessel was made by a Technical Assistance Agreement between INTA and Bodega Ruca Malen. How automaceración system provides that the fermentation process the must is carried through a submerged cap maceration with permanent also by operation of a pneumatic piston hat rack makes your vertical ascents and career recordable work declines in frequency and intensity. This reciprocating movement causes the entire volume of juice solids make contact with the hat in each race (ascending and descending), the assembly is provided with a twist (120) through a combined mechanism cables. Thus, the assembly becomes helical motion in the juice static mass, increasing juice-solid contact. Source: Diario Los Andes
