Device, for continuous degassing of highly viscous liquid or pasty products, comprises two reaction zones that are formed separately or partially coupled to rotors, the rotor in reaction zone I and/or additionally in reaction zone II exhibits a product inlet device, the rotor in the last reaction zone exhibits a construction in form of a spatial lattice and the rotors with longitudinal bars at their periphery and are provided with anchorages. Device, for continuous degassing of highly viscous liquid or pasty products e.g. for the polycondensation of polyester from bi- or more-functional alcohols and carboxylic acids and their sub types with or without comonomer portions such as: polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycyclohexane dimethylene terephthalate (PCT), polypropylene terephthalate (PPT), polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), polycyclohexane trimethylene naphthalate (PCN) or polypropylene naphthalate (PPN), where the rotor or rotor of systems a
