The invention relates to a food processing system (100) allowing reconstitution and/or structuration and/or texturization of dehydrated food materials such as powders, the system comprising: - a dosing system (50) comprising one or a plurality of containers (20) each container comprising a dehydrated or partially dehydrated food material; - at least one reconstitution food processing unit (10) to which the containers (20) from the dosing system can be connected, the processing unit (10) comprising: at least one product inlet (17) for the food material coming from a container (20), at least one liquid inlet (18) for liquid to be mixed with the food material, and at least one product outlet (16) at one end of the unit (10) for in-line depositing the formed food; - a depositing area (60) where the formed food from the processing unit (10) is dispensed; the depositing area (60) and the at least one food processing unit (10) being moveable with respect to each other in such a way that different food shapes and/or patterns from one or different food materials can be formed in the depositing area (60). The invention further relates to a method for operating a food processing system (100) as the one described.L'invention concerne un système de transformation des aliments (100) permettant la reconstitution et/ou la structuration et/ou la texturation de matériaux alimentaires déshydratés tels que des poudres, le système comprenant : un système de dosage (50) comprenant un ou une pluralité de récipients (20), chaque récipient comprenant un matériau alimentaire déshydraté ou partiellement déshydraté ; au moins une unité de transformation des aliments par reconstitution (10) à laquelle les récipients (20) du système de dosage peuvent être reliés, l'unité de transformation (10) comprenant : au moins une entrée de produit (17) pour le matériau alimentaire provenant d'un récipient (20), au moins une entrée de liquide (18) pour un liquide à mélanger avec le matériau alimentaire, et
