The invention relates to a device for the piping of process systems in the food and beverage industry, according to the preamble of independent claim 1 or independent claim 2, and a method of operating such a device. The invention is particularly applicable in situations where the process systems serving for product processing and product transfer must meet stringent microbiological quality requirements and requirements for maximal cleanability under flow conditions (so-called "CIP capability" (clean in place)). The underlying problem of the invention was to devise a device for piping, of a general described type, which device has high operating safety and meets the highest requirements for quality of the fluid products processed in it, which device overall (particularly its anti- mixing valves) is also easy and inexpensive to fabricate, and which, under all practically occurring arrangement variants of the valve distributor tree in relation to the associated process aggregate or tank of the process apparatus, in [sic] the respective valve distributor tree, reproduces [sic], to the extent possible, the same technological conditions and condition parameters as in the process aggregate or tank; wherewith, inter alia, the process engineering problem is clearly delineated with respect to the last-mentioned aspect. This problem is solved in that: .cndot. the respective valve distributor tree (B1, B2, ..., Bi, ..., Bn) opens immediately into the lower tank bottom (T1a, T2a, Tia, ..., Tna) of a respectively associated tank (T; T1, T2, ..., Ti, ..., Tn) of the process system, and/or .cndot. the respective valve distributor tree (B1, B2, ..., Bi, ..., Bn) is connected via an associated pipe connection (R; R1, R2, ..., Ri, ..., Rn; Ux.1; U1.1, U2.1, U3.1, ..., Ui.1, ..., Un.1) to an associated process aggregate (P; P1, P2, ..., Pi, ..., Pn; P**; P1**, P2**, ..., Pi**, ..., Pn**) or to the lower tank bottom (T1 a , T2a, ..., Tia, ..., Tna) or tank (T*; T1 *, T2*, ..., Ti*, ..., Tn*; T**; T1**, T2**, ..., Ti**, ..., Tn**) of the process apparatus, and the pipe connection (R; Ux.1) opens out into the tank-side or process-aggregate-side end of the valve distributor tree (B1, B2, ..., Bi, ..., Bn); .cndot. a stirring device (16) which is operative in the entire interior space of the hollow structure (B1a, B2a, ..., Bia, ..., Bna) is disposed in the valve distributor tree (B1, B2, ..., Bi, ..., Bn); and/or .cndot. the valve distributor tree (B1, B2, ..., Bi, ..., Bn) with the entire interior space of the hollow structure (B1, B2, ..., Bi, ..., Bn) is part of a circulation line (U; U1, U2, U3, ..., Ui, ..., Un) which extends over the tank (T; T*; T**) or the process aggregate (P, P*); and/or .cndot. the valve distributor tree (B1, B2, ..., Bi, ..., Bn) can be recuperatively acted upon by a heat transfer medium (W).
L'invention concerne un système de tuyauterie pour des installations de traitement des industries alimentaires et des boissons. Selon l'invention, l'arbre de vannes de distribution considéré débouche directement dans le fond inférieur d'une cuve associée à l'installation de traitement ou/et l'arbre de vannes de distribution est relié par une canalisation tubulaire à un groupe de traitement associé ou à une cuve associée de l'installation de traitement et la canalisation tubulaire débouche dans l'extrémité de l'arbre de vannes de distribution située du côté de la cuve ou du groupe de traitement. Dans l'arbre de vannes de distribution est disposé un équipement d'agitation occupant la totalité de l'espace intérieur de la structure creuse ou/et l'arbre de vannes de distribution avec la totalité de la structure creuse de l'espace libre est intégré à une conduite de dérivation passant par la cuve ou le groupe de traitement ou/et l'arbre de vannes de distribution peut être exposé dans un but de récupération à un fluide caloporteur.
