Abstract

LA PRESENTE INVENTION SE RAPPORTE A UN PROCEDE DE SECHAGE DE PRODUITS, NOTAMMENT DE PRODUITS AGRICOLES, A L'AIDE DU POUVOIR CALORIFIQUE DU RAYONNEMENT SOLAIRE ET A UN DISPOSITIF POUR LA MISE EN OEUVRE DE CE PROCEDE. CE PROCEDE S'APPLIQUE A DES PRODUITS STOCKES DANS UN SECHOIR DE TYPE CONNU, ET SE CARACTERISE EN CE QUE L'ON SECHE UNE CERTAINE QUANTITE D'AIR, ET QU'ON ELEVE SA TEMPERATURE AU CONTACT D'UNE SOLUTION PREALABLEMENT CONCENTREE A L'AIDE DE L'ENERGIE SOLAIRE ET RENDUE DE CE FAIT AVIDE D'EAU; ON SEPARE D'UNE PART L'AIR AINSI SECHE ET CHAUFFE ET D'AUTRE PART LA SOLUTION DILUEE A LA SUITE DE L'ABSORPTION D'UNE CERTAINE QUANTITE D'EAU CONTENUE DANS L'AIR ATMOSPHERIQUE; ON REINTRODUIT LA SOLUTION DILUEE DANS LE DISPOSITIF DE CONCENTRATION SOLAIRE EN VUE D'UNE NOUVELLE CONCENTRATION; ON FAIT CIRCULER L'AIR CHAUD ET SEC DANS LE SECHOIR AU CONTACT DES PRODUITS A SECHER. APPLICATION AU DOMAINE DE L'ENERGIE SOLAIRE.
