Cooker

摘要

A cooker in the form of a tube heat exchanger, comprises deflection plates along a narrow edge area and provided with segment-like openings on diametrically opposing sides of the inner wall of a jacket housing. The opening in the first plate in the flow direction, lies opposite a material introduction pipe fitting and the opening in the last plate lies opposite a withdrawal pipe fitting. <??>A cooker in the form of a tube heat exchanger, comprises a bundle of narrowly spaced tubes extending within a jacket housing (1) and flowing over by material introduced and withdrawn by pipe fittings on the jacket. Deflection plates (5) are provided in the jacket housing which define flow chambers as well as openings for the transition of the material to be treated from one flow chamber to the next. They are provided with segment-like openings (6) along a narrow edge area. The openings are situated on diametrically opposing sides of the inner wall of the jacket housing. The opening in the first deflection plate in the flow direction, lies opposite the material introduction pipe fitting (11). The opening in the last deflection plate lies opposite the withdrawal pipe fitting (12).
