Pluviatank
Pluviatank is an innovative gravity flow vinification system which guarantees high and constant quality in red wine production. Thanks to a user-friendly and highly flexible electronic system, you can program the intensity and frequency of the cycles of pumping the must over the cap during fermentation, the must temperature and the running of the marc extractor blade. All these functions can be executed automatically and save on human labour. The work cycle consists of collecting at least 10% of the liquid volume of the pressed grapes, pumping it to the higher tank until it's filled and pouring it all onto the marc cap within a few seconds, giving off a very high quantity of energy, generated by must flow with a fixed shape determined by the special valve shape. In this way you can properly crush the marc cap and wash the grapes as well.
The system consists of:
- a pump for must loading
- an upper filling tank, equipped with a pneumatic actuator
- power assist - an electronic control panel
Advantages:
- flexible use
- intense extraction of pigments, polyphones, anthcyanins and all the noble substances contained in the grapes
- homogenisation of temperature of fermentation mass
- effective oxygenation - save on human labour
- increase productivity due to faster vinification
- intensity of flavours and fragrances, stability of colour
