ABSTRACT:
A blade system for a scraped surface heat exchanger includes a number of blade rows which each consists of a number of successively arranged blade scrapers (1) mounted in cut-outs (15) in the surface of a rotor (4) which is mounted in a heating/refrigerating chamber (20) in the heat exchanger. The individual blades, at the edge closest to the inner wall (21) of the chamber (20) are provided with a knife edge (2) and at the edge facing the rotor (4) with a basis (3). The blades are being provided with flaps (8) which are bent in the direction towards the rotational axis of the rotor (4), while elements (9) on the rotor (4) form abutments for the flaps (8) and engagement members (10) for receiving the basis (3) of the blades so as to permit removal of the blades from the heat exchanger without simultaneously dismounting the rotor (4).
