A plant (1) for de-aerating and heating a vegetable product (100) comprises an extraction section (80) in which a vegetable starting product (5) is treated, in order to obtain an extracted vegetable product (100), in particular a puree, or a vegetable juice. The extracted vegetable product (100) is fed to a cold de-aeration section (10) obtaining an extracted vegetable product and de-aerated cold (105). The plant (1) also comprises a heating section (20) in which the de-aerated vegetable product (105) is heated from the starting temperature Tl to a final temperature T2, with T2>；T1, obtaining a heated de-aerated product (110). The plant (1) also comprises a storage reservoir (30) of the de-aerated vegetable product. According to the invention, the storage reservoir (30) is located downstream of the heating section (20), proceeding along the conveying direction of the de-aerated vegetable product through the plant (1). Therefore, the de-aerated vegetable product present in the storage reservoir (30) is a vegetable de-aerated and heated product (110). The plant (1) also comprises a deviation means (50) located downstream of the storage reservoir (30) and arranged to feed selectively the heated de- aerated product (110) in an outlet duct (41), for transferring the product out from the plant (1), or in a recirculation duct (42), for recirculating the product at a recirculation point (60) of the plant (1) [Fig. 1].L'invention concerne une installation (1) de désaération et de chauffage d'un produit végétal (100) comprenant une section d'extraction (80) dans laquelle un produit de départ végétal (5) est traité en vue de l'obtention d'un produit d'extrait végétal (100), en particulier une purée ou un jus végétal. Le produit d'extrait végétal (100) est introduit dans une section de désaération froide (10) en vue de l'obtention d'un produit d'extrait végétal désaéré et froid (105). L'installation (1) comprend également une section de chauffage (20) dans laquelle le produit
