A process for continuously carrying out enzymatic reactions on an organic substrate, which comprises the steps of: • a) providing a turbo-reactor (T) comprising a cylindrical tubular body (1) having inlet openings (5, 6) and a discharge opening (7) and a rotor, comprising a shaft (8) provided with radially projecting elements (9), and feeding a continuous flow of the organic substrate into the turbo-reactor, • b) feeding into the turbo-reactor, together with the flow of organic substrate, a continuous flow of an aqueous solution of an enzyme, • c) centrifuging the particles and the droplets against the inner wall of said turbo-reactor, with formation of a thin, tubular, fluid layer,; • d) starting the conversion of the organic substrate into the desired product by means of the enzyme in the thin layer; • e) discharging from this opening a continuous flow of a mixture comprising the product, the enzyme and the organic substrate which has not yet reacted, • f) feeding this continuous flow into a maturation reactor (M), comprising a box-shaped body (12), provided with a screw-type rotor (18); • g) subjecting this continuous flow to continuous mixing; • h) discharging from the reactor (M) a continuous flow of product and enzyme; • i) subjecting this continuous flow to a thermal treatment at a temperature of at least 70°C, in order to inactivate the enzyme. |
