摘要

The heat exchanger of the type envelope and tube and inner tube, and / or the cover of a heat exchanger of the type envelope and tube.The heat exchanger body and pipe (W) for the treatment of juice products and foodstuffs like juice with medium to high viscosity.With at least one tube with the cover (1) which contains at least one inner tube (2) with which the inner tube (2) and / or the tube with the cover (1) is formed like a spiral tube with multiple starting coils that function as a thread in an angle ( 225 , 225 1) in relation to the axis of the tube, u (x) M cross tube and twisted with spirals Crusades (D1,D2) at least essentially symmetrical to the axis of the tube, each with an angle of incidence ( 244 , 244 1) between 67 and 72 198 198 in relation to the tube axis (x), that is, with an angle of twist ( 225 , 225 1) 23 198 198 18 in relation to the axis of the tube, which is used as a The tube internal and / or external (1, 2). The depth of the spiral (T) is approximately 0.8 mm to 1.2 mm.
