In second annular groove 121, and 122 circumferential wall of annular slab is fixedly connected with 4 outer wall of outer cylinder；Since the weight of inner cylinder 5 is larger, annular
Plate 122 is entrenched in the inner cylinder 5 that is set as in the second annular groove 121 and provides secondary support, further strengthens the support of inner cylinder 5
Power, it is even more important that the setting of annular slab 122 plays sealing function to cavity 6, to improve the thermal insulation property of cavity 6, adds
Fast inner cylinder 5 by thermal velocity.
Deflector 13 is welded on the inner wall of inner cylinder 5.Since the material viscosity being heated reduces, when mixing speed is larger
When, fluid foods easily pour into the inner wall of inner cylinder 5 under the influence of centrifugal force, cause 5 surrounding material face of inner cylinder to rise, center material
Face decline, to form whirlpool.The setting of deflector 13, so that the tangential flow of fluid foods is changed into axial flowing and radial direction
Flowing, while eliminating whirlpool, accelerates the speed that the heat of 5 surrounding material of inner cylinder is transmitted to 5 center of inner cylinder, so that inner cylinder
Material is heated evenly in 5.
When the present embodiment is in use, material is sent into inner cylinder 5 from feed inlet 21, then starts driving motor 9, as master
Moving gear 101 provides power, since driving gear 101 is between driven gear ring 102 and driven gear 103, driving gear 101
Drive driven gear ring 102 and driven gear 103 to rotate when rotation, thus drive turbo blade 31 in inner cylinder 5 and rotation axis to
Opposite direction rotation；Steam is passed through in cavity 6 by air inlet pipe 7 again, the inner cylinder 5 of rotation compared with fixed inner cylinder 5, by
Heat is more uniform, efficiently solves the very fast and separate steam inlet duct 7 that is heated inside the autoclave body 1 of 7 side of steam inlet duct
The heated slower problem of the autoclave body 1 of side reaches good stirring effect so that the material in inner cylinder 5 is uniformly heated
Fruit.
