Dehydration of liquid, semisolid or water-containing products comprises sealing the product in a semipermeable bag and heating it in a vacuum chamber
Process for dehydrating a liquid, semisolid or water-containing product comprises sealing the product in a bag that is permeable to water vapor and air but not to liquid water; placing the bag in a chamber whose internal walls are at least 5[deg]C hotter than the desired product temperature; and eva...

| description | Process for dehydrating a liquid, semisolid or water-containing product comprises sealing the product in a bag that is permeable to water vapor and air but not to liquid water; placing the bag in a chamber whose internal walls are at least 5[deg]C hotter than the desired product temperature; and evacuating the chamber. Independent claims are also included for the following: (1) apparatus for carrying out the above process, comprising a chamber (1) having internal walls or plates (2) with means for circulating hot liquid or steam produced in an external oil-liquid heat exchanger in which the oil is heated by external means or by heat generated by the adsorption of water on a zeolite and the sensible heat of regeneration of the zeolite; (2) a product dehydrated by the above process without any additives.
Procédé permettant la déshydratation de produits liquides ou pâteux contenant de l'eau, liquide pouvant mousser. L'invention utilise les systèmes de pompage décrit dans le brevet FR89 17413 la zéolithe utilisée assurant la fixation de l'eau et le chauffage. L'eau est évaporée au travers une membrane semi-perméable fabriquée préférentiellement par enduction de diméthylpolysiloxane sur un tissus de fibres synthétiques.Le procédé selon l'invention est remarquable en ce que le produit (4) à déshydrater est placé dans un sac ou au moins une partie dudit sac (3) est constitué de membrane citée ci dessus, il est placé dans une enceinte (1) munie de moyen de chauffage, (2) la pression dans l'enceinte est maintenue entre O, 1 et 50 mb, la pression dans le sac pouvant varier de 2 à 2000 mb. |
