Abstract

a invenção se refere a um processo para tratamento de produtos alimentícios líquidos (p) sensíveis ao calor, a uma instalação para realização do processo e a uma bomba centrífuga para tal instalação. isto é alcançado com a técnica de processos, com as seguintes etapas de tratamento (a) e (d): o produto alimentício líquido (p), (c) sofre um terceiro resfriamento (k3) em uma tampa de alojamento (8) de um alojamento de bomba (12) da bomba centrífuga (54), conectado ao tubo de saída (52) ou bocal de sucção (76); (d) serve, com uma parte de seu fluxo volumétrico transportado, em uma roda impulsora (100) da bomba centrífuga (54), configurada aberta para a tampa de alojamento (8) da bomba centrífuga (54), uma lavagem planejada do alojamento de bomba (12) e da roda impulsora (100), através de uma fenda posterior (s1) de roda impulsora que está prevista entre uma parede de alojamento (10) da bomba centrífuga (54) e a roda impulsora (100), e através de uma fenda anterior (s2) de roda impulsora que está prevista entre a tampa de alojamento (8) e a roda impulsora (100), os fluxos volumétricos das lavagens planejadas superam em até um múltiplo os fluxos de compensação forçados dentro do alojamento de bomba (12), os quais resultam de um desenho otimizado hidraulicamente da bomba centrífuga (54) com uma respectiva fenda posterior mínima e uma fenda anterior mínima (s1*, s2*), as quais garantem a funcionalidade mecânica da bomba centrífuga (54).The invention relates to a process for treating heat sensitive liquid (P) food products, a process facility and a centrifugal pump for such an installation. This is achieved with the process technique, with the following treatment steps (a) and (d): the liquid food product (p), (c) undergoes a third cooling (k3) in a housing cover (8) of a pump housing (12) of the centrifugal pump (54), connected to the outlet tube (52) or suction nozzle (76); (d) serves, with a portion of its volumetric flow conveyed, on a centrifugal pump (54) drive wheel (100) configured open for the centrifugal pump (54) housing cover, a planned wash of the housing (12) and the impeller wheel (100) through a rear impeller wheel slot (s1) which is provided between a housing wall (10) of the centrifugal pump (54) and the impeller wheel (100), and Through an anterior impeller slot (s2) which is provided between the housing cover (8) and the impeller wheel (100), the volumetric flows of the planned washes exceed the forced compensation flows within up to a multiple of (12), which result from a hydraulically optimized design of the centrifugal pump (54) with its minimum back slit and a minimum front slit (s1 *, s2 *), which guarantee the mechanical functionality of the centrifugal pump (54) .
