It was born to improve the fermentation process increasing the efficiency, reducing time and eliminating unnecessary installation cost. It is based on the direct reuse of CO2 from fermentation process or we can use any other inert gas, which reintroduced into the liquid phase under cap, with a suitable pressure and flow rate, allowing the displace a huge quantity of liquid necessary to fragment and mix the skin cap. It allow you to save working time, this achieves to anthocyans protection from oxidation (environment under CO2 protection), improves polyphenols extraction and preserve aromatic compounds. It can be equipped with a manual or automatic injection hose and is managed by a programmable control system It is available in two version, standalone and plant system on the tank.
