Process for adsorbent obtaining and process for demetalation of wine-making products with utilization thereof
Abstract
The invention refers to the wine industry, in particular to a process for adsorbent obtaining and to a process for demetalation of wine-making products with utilization thereof.According to the invention, the process for adsorbent obtain of perlite at a temperature of 120…160°C during 1…2 hours, comminution, carbonization in isothermic conditions at a temperature of 450…500°C during 2…3 hours in nonoxidizing atmosphere and electrochemical activation in 3…5% solution of potassium or sodium orthophosphate in the anodic chamber of the diaphragm cell, the anodic current density being of 2…3 A/dm3 during 5…10 min.The process for demetalation of wine-making products with utilization of the adsorbent obtained by said process is carried out with adsorbent fluidization in a dose of 6…10 g of adsorbent per 1 g of iron and/or copper compounds during 15…20 min.The result consists in increasing the different and in intensifying the process for demetalation of wine-making products.

The invention relates to the wine industry, in particular to a process for obtaining the adsorbent and to a process for demetallizing the products of the wine industry with its use.
According to the invention, the process for obtaining the adsorbent includes drying of the sediments resulting from the filtration of the wine with the use of perlite at a temperature of 12O ... 16O ° C for 1 ... 2 hours, crushing, carbonization under isothermal conditions at a temperature of 450. ..500 ° C for 2 ... 3 hours in a non-oxidizing atmosphere and electrochemical activation in potassium or sodium orthophosphate solution of 3. .5% in an anodic sheath of the electrolyser with diaphragm 2 rn, at an anodic current density of 2 ... 3 А / dm<sup>1 2</sup> for 5 ... 10 min.
The process of demetallization of the products of the wine industry with the use of the adsorbent obtained by the mentioned process is carried out with the pseudolysis of the adsorbent in a dose of 6 ... 10 g Ιθ adsorbent to 1 g of iron and / or copper compounds within 15 ... 20 min.
The result consists in increasing the efficiency and intensifying the demetallization process of the products of the wine industry.
