Abstract

An externally cooled cylindrical vessel has a draft tube centered in the lower half thereof. A continuous circulation seeded with tartars crystals includes a fast downward flow through the draft tube and a slow upward flow outside the draft tube. The circulation induces crystal growth and the removal of tartars from the liquid. A coning zone is defined in the vessel above the draft tube. The slow upward flow moves toward the calming zone, facilitating classification of the crystalline matter which is reintroduced into the fact downward flow. The liquid product from which the tartars has been removed and which is collected in the upper section of the vessel is tapped off by an overflow port located near the top of the vessel.
