Full Text | Pasteurising installation The invention refers to a pasteurising installation for the pasteurisation of products in containers as per the generic term of claim 1 In the beverage industry, it is in particular used in easily perishable goods, to pasteurise these items. In known pasteurising installations, therein the containers are delivered with the products in practically uniform movement from entry area to the exit area. During this movement these are heated up till these have picked up the desired pasteurising units, thereafter cooled, with which the pasteurising process is completed. A pasteurising passage planned for this has accordingly, a heating up section, a super heating and pasteurising section with a following cooling section. The individual sections can have further sub zones. The gradual heating up and cooling down ensured through it is in particular preferred for the glass bottles used in the beverage industry in order to avoid a destruction of glass bottles through abrupt change of temperature. The heat transmission to the products contained in the containers takes place normally through spraying of these containers with water, which are moved forward on a conveyor belt which permits the spray liquid to pass through downward. Below the conveyor belt the collecting containers for the spray liquid are brought, from which the pumps for the spray are fed. Between the heating up and cooling down sections zone wise heat can be exchanged with the spray liquid. In order to reach an optimum gradation of temperature in the individual sections, these are correspondingly subdivided. Mostly, the section "heating up" has three to four individual zones, the pasteurizing area has two to three zones, in doing so yet a super heating zone can be planned before the pasteurising zone. The adjoining section "cooling down" has again three to four individual zones in whiGh the containers are cooled down through a stepwise decreasing temperature of the spray liquid up to the desired exit temperature. The spray temperatures adjusted in each case are matched exactly to the product, the length of the zones and the speed of the conveyors, so that it is ensured that the product contained in the containers attains the specified degree of pasteurisation. For the purpose of spray of the containers, in the pasteurising unit housing, trans- verse to the delivery direction a multiple number of spray tubes with spray nozzles or spray openings maintained at spacings adjacent to each other and a sidewise liquid feed are provided. Spray tubes of this type are known as for example from the DE 29716644. Proceeding from a such pasteurising installation the assignment lies at the base of the invention to reduce the required manufacturing-, erection-and commissioning cost of these installations as well as of their pasteurising unit housing and to procure standardised housing module for preferably almost all execution types. This assignment lying at the base of the invention is now solved through it that the passage housing is built in modular design out of any number of flexible,interchangeable segments, in doing so these segments run transverse or longitudinal to the delivery direction of pasteurising unit and may be positioned and placed serially one after the other on zonal tanks and/or hot water tanks showing parallel or longitudinal to this delivery direction. With this design and the features represented in further claims as well as in description supplements simple housing base modules are present which show a high equal part share and which permit a series production of many components. Moreo- ver, it provides a flexible zonal structure for an optimum machine lay out, in doing so on the whole the standardised housing modules are suitable for almost all execu- tion types of heat treatment machines for containers like pasteurising unit, recooler, heater and so on. In the following the invention is explained closer with the help of a diagram with Figures 1 to 5 representing an execution example. In Figure 1 and the following description, in addition to this, first it is referred to a general pasteurising installation and the course of it's process. In the Figures 2 to 5 then the corresponding housing structure in shape of an execution example is explained. Therefore, the pasteurising installation comprises a heating section 2 assembled in flow direction of the respective container 1 in starting area, which can again com- prise a multiple number of individual zones 5-7, in doing so the heating phase is taken up correspondingly carefully. A super heating zone 8 connects to a heating section 2 this follows the actual pasteurising zone 9. Connectingly the area of the cooling section 4 starts which like aiso in other sections, can comprise a larger number of individual zones 10-12. The operating program of such a pasteurising installation is laid out first for the pasteurising operation under optimum conditions. Thus it is as for example planned that the first heating zone 5 shows a spray temperature of 18°C. Correspondingly the exit temperature of the pasteurised products is planned with a spray temperature of 17°C. The second heating zone 6 shows a spray temperature of slightly above 24°C, in doing so the cooling zone communicating with it can again He slightly lower at 23°C. At the example of both these zones it is identifiable that the water out of the zones "cooling" 4 in each case is supplied to the zone in section "heating 2" whose desired heating temperature comes nearest to the desired cooling tempera- ture. For balancing of the respective temperature difference, preferably water from the first tank 13 is supplied in minor amount to water out of cooling section 4, whose water of higher temperature comes from the last station 7 of the heating section 2. In connection to the heating section the superheating zone 8 is located whose temperature is again higher than the temperature of the last heating zone 7 and is fed from a second container 15 with higher temperature in contrast to the first container 13. A third container 16 is allocated to the second container 15 to which the excess water of the container 15 is supplied. This third container 16 is in addition maintained at a predetermined higher temperature by means of a heating equipment. From this container 16 also the super heating- and pasteurising zone 8, 9 are serviced, in doing so the draining hot water quantity is collected in the second container 15 and is mixed with hot water of the third container 16. in case of an arising disturbance, as for example caused through a container back pressure in the pasteurizing installation, through a not further represented control equipment a careful activation of definite valves is taken up, so that as for example the water of less temperature is supplied from the fixed container 13 to the super heating- and/or pasteurising zone 8, 9. Likewise water of less temperature can be supplied to other sections 2, 4 as for example to a fourth container 14. The device itself, as per the Figure 2 to 5 in shape of a pasteurising unit housing, is a modular housing construction out of multiple number of segments, in doing so, the lower structure out of pre erected zone tank 21 comprise the pipelines,valves and wiring to which sidewise the pipelines 22 in joint or individual segments are allocated. From these at spacing the segments 24 of hot water buffer tanks run. The free space remaining in between is planned as crawling way 25 for maintenance cases, as Figure 2 shows. In Figure 3 the interchangeable and flexible segment 6 of the real passage housing is represented. These individual segments contain the conveyor belt substructure with a back strand support as well as the spray distributor and a lid structure preferably with external ribbings. The side openings 28 are sealable with side panels 29 which may be brought sidewise. The passage segments 26 are put on as per Figure 4 transverse to the convey device of pasteurizing unit running on the zone tank 21 and the hot water tank 24 located for this at distance. The passage segments 26 are equipped in the base area with sliding items, assembly rolls or rearrangeable sliding rolls for the simplified local shifting and are to be placed in horizontal level which may be moved as well as may be lined up in series to each other. In this way the passage segments 26 form as per Figure 5 a compact housing structure 30 which form through front sided pre connection of the actual inlet - and outlet segment 31 a complete, each time reducable or expandable pasteurizing installation. Therein the machine width forms on the whole also the treatment width, in doing so the compact housing structure is limited purely by narrow side panels 29. These are held sealing free in the side wall formations 20 of the segments 26 and purposefully supported in a water carrying lower frame 32. In place of this passage segments aligned transverse to the delivery device of the pasteurizing unit, also segments can be used which may be lined up one after the other in series parallel to the delivery direction, in doing so the substructures run in shape of tanks 21 and 24 transverse to the actual delivery direction. The frame of the segments 26 can as for example be shaped out of tubes, square tubes or the equivalent. The outfit parts like spray tubes, spray distributors, delivery goods sub structure, back strand support and further are preferably integral com- ponent of the segment construction and consequently are also planned for the stiffening of the system. The standardised housing segments are built in form of assembly structure groups, in doing so their dimensions correspond to the permitted usual container sizes as for example of a ship-or sea container. The zone tanks can additionally be equipped with endless- belt screen dirt- and fragment conveyors. In the regenerative zone a cascading cooling or hot water run is planned for optimum utilisation of the energy of hot or cooling water. The water management is taken up over stepped weirs in doing so the level of the zones is maintained through suitable medium like as for example corresponding sensors and frequency regulated pumps. The erection of pasteurization installation takes place preferably as per the features of the claims 15, to which it is referred correspondingly. Patent Claims 1.
