A method for treating a vegetable product in form of crushed material comprising the steps of (i) storing the crushed material in a first vat (10) to let it ferment and form a cap (34) of solid parts floating on a liquid mass (30) therein; (ii) connecting a second vat (12) to the first one to gather in it the gaseous products (32) generated due to fermentation; (iii) isolating the two vats; (iv) reducing the gaseous pressure in the first vat; (v) connecting the second vat to the first at a point beneath the cap so that, due to the differential pressure between the two vats, spontaneous racking of gaseous products in the liquid mass occurs, in such a manner that rising they get into contact with the cap. |
