Definizione

Machine consisting of a hopper, an Archimedean screw and a horizontal or vertical rotating drum, against which a more rapidly rotating paddled shaft presses the grapes. 1

Nota

A firm specializing in mechanical separation has developed a centrifugal process for extracting juice from grapes. The process is used for the processing of red wine. It functions as follows: after the stems are removed from the grapes in the basket centrifuge and they have been heated to 82° C to produce an intense colour, the so–called must is fed into a decanter. In a rotating drum, centrifugal force flings the grapes against the drum wall and separates the must from the solid components. Solids are conveyed to the outlet with the aid of a worm rotating at a different speed. The must, on the other hand, stays inside and is drained off in the opposite direction where the vintner can start its fermentation. The results are convincing. 2

Contesto

There are various types of press machines: the crusher and stalk separator (that by beating and rolling separates the stalks from the must); the roller crusher (two fluted cylinders turning in opposite directions and squeezing the berries between them); the centrifugal grape mill (squeezing the berries by spinning and pressing them against the machine walls). 9
