Abstract
Abstract A method serves for treating liquid foodstuffs, in particular red grape mash. It comprises the steps of filling the mash (40) into the tank (10) from below until the upper level (43) of the mash is above a sieve (31) which is arranged in the upper portion of the tank (10), which fills the whole cross-sectional area thereof and which serves to retain pomace components (41) of the mash (40), and surrendering the mash (40) in this condition to fermentation for a pre-determined period of time. The sieve (31) used is rotatable about one horizontal axis (33) and the mash (40) is stirred at the end of a pre-determined period of time by rotation of the said sieve (31).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
Apparatus for treating liquid foodstuff containing solid particles, in particular for treating red grape mash, comprising: a tank adapted to be filled with said liquid foodstuff up to a level at a first predetermined vertical coordinate position, said tank having a predetermined horizontal cross-section area at a second predetermined vertical coordinate position located below said first vertical coordinate position; a sieve spanning an area corresponding to said horizontal cross-section area, said sieve being mounted in the tank for rotation about a substantially horizontal axis located at said second vertical coordinate positions; said sieve being permeable to said liquid foodstuff but impermeable to said solid particles; first tube means connected to said tank at a location between said first and said second vertical coordinate positions; second tube means connected to said tank below said second vertical coordinate position, said first and second tube means being in communication with one another; and pump means for establishing a flow of said liquid foodstuff through said first and second tube means and sieve.
Claim 2
Dependent Claim
169 words
Apparatus for treating liquid foodstuff containing solid particles, in particular for treating red grape mash, comprising: a tank adapted to be filled with said liquid foodstuff up to a level at a first predetermined vertical coordinate position, said tank having a predetermined horizontal cross-section area at a second predetermined vertical coordinate position located below said first vertical coordinate position; a sieve spanning an area corresponding to said horizontal cross-section area, said sieve being mounted in the tank for rotation about a substantially horizontal axis located at said second vertical coordinate positions; said sieve being permeable to said liquid foodstuff but impermeable to said solid particles; first tube means connected to said tank at a location between said first and said second vertical coordinate positions; second tube means connected to said tank below said second vertical coordinate position, said first and second tube means being in communication with one another; and pump means for establishing a flow of said liquid foodstuff through said first and second tube means and sieve.
Claim 3
Dependent Claim
82 words
Apparatus according to claim 1, including: a radial pipeline extending in said sieve and disposed to receive the liquid foodstuff from said second tube means; a downwardly extending arm on said sieve presenting an axial pipeline communicating with said radial pipeline to receive the liquid foodstuff therefrom; and a spray head on a lower end of said arm providing upwardly directed nozzles for receiving the liquid foodstuff from the axial pipeline and spraying same into the tank in a generally upward direction.
Claim 4
Dependent Claim
17 words
Apparatus according to claim 1, including heat exchange means on said sieve for heating the liquid foodstuff.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 1, including vertically adjustable mountings for mounting said sieve to the tank.
