Definitions
- the invention relates to a method for cit ⁇ c acid purification and concentration of cit ⁇ c- hquors from citric acid fermentation
- cit ⁇ c-hquor is used for solution obtained after fermentation at citnc acid production
- citnc- quors contam except for 10 to 20 % w/w of water and organic acids also proteins in amount of 0 1 to 1 % w/w and reducing sugars in amount of 0 5 to 5 % w/w from which the compounds are formed at mcreased temperature e g 60° C in evaporator, assigned as readily carbonisable substances
- the presence of these substances in product serves as an indicator of citnc acid punty
- Permeate from the second stage is divided to three technological flows according to residual content of citnc acid Technological flow with content of 0 01 to 1 % w/w of citnc acid may be used as a source of water for fermentation Technological flow with content of 1 to 10 % w/w of citnc acid may be used for washing out the citnc acid residue from concentrate at pre-treatment/diafiltration/, while the permeate from diafiitration enters again nanofiltration Technological flow with content of 10 to 20 % w/w is returned for nanofiltration
- Concentration and pu ⁇ fication of citnc acid from citnc-hquors obtained after citnc acid fermentation by nanofiltration through polymenc membranes may be performed regarding to different permeability and selectivity towards the compounds in citnc-hquors Exactly expressed, the pu ⁇ fication effect is provided by higher selectivity of membranes towards citric acid as to reducing sugars In this way both separation effect and concentration effect are secured
- the claims for energy consumption are twenty time lower regarding to different energy consumption at water separation by classical method - evaporator
- the method according to the invention represents an economic solution of the part of technology for citnc acid production, considered for an important product assigned especially for food and pharmaceutical industry

Abstract
Des liqueurs d'acide citrique qui constituent une solution d'acide citrique après fermentation subissent une nanofiltration en deux phases sur des membranes polymères. Dans la première phase, la nanofiltration est exécutée sur des membranes polymères dont le seuil d'arrêt nominal de poids moléculaire est de 10 000 à 20 000 daltons et, dans la deuxième phase, sur des membranes polymères dont le seuil d'arrêt nominal de poids moléculaire est de 200 à 400 daltons. Le produit concentré ainsi obtenu après la deuxième phase subit une cristallisation appropriée et le perméat est recyclé dans des étapes particulières de processus techniques.
