Stabilization plants: continuous tartaric stabilization by membrane
Proper stabilization of wines is an immediately noticeable feature by consumers that wine is proposed.
Potassium and tartaric acid are substances naturally contained in the grapes, but are clearly separate. At the time of pressing these together are under waterlogging conditions must. The wine that will result will therefore be subject to certain and obvious phenomena of precipitation of BITARTRATE (KHT) potassium salts because even the yeast action allows a substantial reduction in fermentation phase.
One of the traditional methods to resolve the problem consists stabilization by reducing sedimentation through cold and successive filtration cartridges before bottling.
DT Separtech proposes instead a system based on separation by wrapped spiral polymer membranes. This method creates the rapid oversaturation of tartaric acid and potassium allowing activation of the nucleation of the germs of crystallization followed after their growth. These crystals will be removed on stage filtration of wine with filters of new generation of 3 microns.
The obtained concentrate wine is free of tartrates and mixes then promptly to permeate before last stored in vats.
Advantages: Economically advantageous treatment by need low energy consumption, never more than 20 kW and also thanks to the simple automated management of the entire cycle.
Normally there is no need for adjuvants of crystallization.
Maximum respect to the organoleptic characteristics of the treated wines, white, red or pink.
