Abstract

Procédé et appareil pour séparer et récupérer le nitrate de potassium d'un extrait de tabac. Le procédé selon l'invention consiste à concentrer en 15 les extraits solubles du tabac, à envoyer le produit dans un cristallisoir 10 dans lequel il est refroidi pour provoquer la cristallisation et ensuite la séparation dans un premier séparateur 12 pour obtenir un extrait dénitrifié 2 et l'adjonction d'eau de dilution dans un récipient mélangeur 13, le produit étant envoyé à un second séparateur 14 pour obtenir du nitrate de potassium en 5 et pour recycler l'eau de dilution à travers une canalisation 6. Fabrication du tabac reconstitué.A method and apparatus for separating and recovering potassium nitrate from a tobacco extract. The process according to the invention consists in concentrating in the soluble extracts of tobacco, in sending the product to a crystallizer 10 in which it is cooled to cause crystallization and then to separation in a first separator 12 to obtain a denitrified extract 2 and the addition of dilution water in a mixing vessel 13, the product being sent to a second separator 14 to obtain potassium nitrate at 5 and to recycle the dilution water through a pipe 6. Manufacture of reconstituted tobacco.
