Abstract
Inventia se refera la un procedeu si la o instalatie pentru uscarea produselor, prein trecerea unui curent de gaze printre ele pentru extragerea umiditatii, si la un dispozitiv de conectare care produce cel putin un strat de lichid deshidratat în vecinatatea produsului care urmeaza sa fie uscat, start de lichid care elimina umiditatea din curentul de gaze. Curentul de gaze este trecut sub forma de bule printr-un strat de lichid dispus orizontal sau poate sa fie trecut printre elementele conducatoare ale filmului de lichid. lichidul deshidratant este regenerat în mod continuu. Prin intermediul cîtorva curenti de gaze partiali si al unei dispozitiv de contactare mai multe module separate de film lichid, este posibil sa se realizeze uscarea de tip contracurent. produsul poate sa fie încalzit la o temepratura predeterminata prin lichidul deshidratant care trece prin curentul gazelor uscate. The invention relates to a process and apparatus for drying the products, passing a gas stream therethrough for extraction of moisture, and to a connecting device which produces at least one dewatered liquid layer in the vicinity of the product to be dried, start of liquid that removes moisture from the gas stream. The gas stream is bubbled through a horizontally arranged liquid layer or may be passed through the conductive elements of the liquid film. the desiccant fluid is continuously regenerated. By means of several partial gas streams and a contacting device several separate liquid film modules, countercurrent drying is possible. the product may be heated at a predetermined temperature by the desiccant liquid passing through the dry gas stream.
