Abstract
The present invention relates to a process permitting the modification of the chemical composition of the inner face of a barrel, consisting in heating and in moistening the inner face of the shell (1) of this barrel, characterized in that it consists in alternately heating and moistening, according to a specified heating power and liquid flow rate, and for a specified time, the heating being distributed over the entire height of the shell. It also relates to a machine implementing this process and comprising a rotating support (12), heating means (19) and moistening means (20, 21, 22) which are vertically displaceable with respect to the main axis of the barrel. Application: barrels for wines and alcohols.
Claims9
A machine for modifying the chemical composition of an inner face of a shell of a barrel having a main axis, comprising:
- means for supporting the shell of the barrel with said main axis oriented vertically;
- means for heating the inner face of the shell;
- means for moistening the inner face of the shell;
- means for supporting and vertically displacing, simultaneously, said heating and moistening means along said main axis;
- and
- means for controlling said heating means and said moistening means so that said inner face of the shell is cyclically, alternately, heated and moistened when said heating and moistening means are moved into said shell by means of said supporting and vertically displacing means.
A process for modifying the chemical composition of an inner face of a shell of a barrel, said barrel having a main axis, comprising the steps of:
- a) placing the shell of the barrel on a rotatable support, with said main axis being oriented vertically and under vertically displaceable heating and moistening means;
- b) rotating the support and the shell about said main axis;
- c) lowering, simultaneously, said heating and moistening means from a first position situated above said shell to a second position situated within said shell;
- said moistening means being disposed under said heating means;
- d) heating the inner face of the shell with a specified heating power for a specified time;
- e) stopping said heating;
- f) lifting up said heating and moistening means from said second position to said first position;
- g) moistening the inner face of said shell with a specified liquid flow rate for a specified time while said heating and moistening means are lifted up from said second position to said first position;
- h) repeating steps c to f;
- and
- i) stopping the rotation of said support.
