Definitions
- the invention relates to a heat exchanger Panel construction according to the preamble of claim 1.
- a such plate heat exchanger for use in the Food and luxury food industry, for example, is out DE 31 17 496 A1 become known.
- the flow resistance to reduce the viscous product has several distribution pipes extending over its top, which in turn lead to plate channels. The flow takes place in the downdraft principle by moving the product from top to bottom flows through the plate channels below.
- Such, on Low flow resistance of designed plate heat exchangers is for use in the confectionery industry where it mainly about cooking sugary Solution mixtures and mixtures with sugar substitutes only suitable to a limited extent.
- the length of the flow path of the product in the heat exchanger simple way to be able to change this one desired, the respective product and the flow rate adjusted length and thus residence time.
- the heating medium for example Water vapor
- Heat transfer area and the temperature difference between the product and the heating medium can be changed to a to achieve optimal adaptation to the product, so too sensitive products can be gently heated.
- the so-called Snake cooker prevailed, although this in terms its size and flexibility compared to a plate heat exchanger has disadvantages.
- the plate-type heat exchanger according to the invention with the characteristic features of claim 1 has in contrast the advantage that it is simple in terms of its Flow length and its flow cross section as well with regard to the amount of heat to be transferred to each product to be processed is customizable. Beyond that his product room is easy to clean and offers the Possibility to adapt to different products.
- FIG. 1 shows a first heat exchanger in a longitudinal section in a schematic representation
- Figure 2 den 1 in a cross section in schematic representation
- Figures 3 and 4 others Embodiments of the heat exchanger with modified Head plates also in longitudinal sections in schematic Representations.
- the heat exchanger 10 shown in FIGS. 1 and 2 in Panel construction is preferably used for heating or cooking sugar-containing solution mixtures and mixtures with Sugar substitutes in the confectionery industry. These mixtures are used as a product for the sake of simplicity designated.
- the housing 11 of the heat exchanger 10 has a box-shaped central part 12 on its respective End faces with an intermediate layer, not shown Seals of a head plate 13, 14 are sealed is.
- the two head plates 13, 14 are preferably with also not shown quick fasteners with the Middle part 12 connected so that an exchange of Head plates 13, 14 is possible in a relatively short time.
- the interior 16 of the housing 11 is by means of two, parallel to the top 17 or bottom 18 of the housing 11 arranged, parallel partition walls 19, 20 in three Sub-rooms 21, 22, 23 divided.
- these subspaces 21, 22, 23 opens into one side wall 24 of the housing 11 in each case an inlet 26, 27, 28 for a heating medium, for example water vapor.
- the inlets 26, 27, 28 are each at the highest point of the respective subspace 21, 22, 23 near the top 17 or the intermediate walls 19, 20 arranged.
- In the other Side wall 29 of the housing 11 is for each subspace 21, 22, 23 each have an outlet 31, 32, 33 for the heating medium arranged.
- the outlets 31, 32, 33 are in turn on the lowest point of the respective subspace 21, 22, 23 near the partitions 19, 20 and the underside 18 arranged.
- Each of the subspaces 21, 22, 23 is not part of one shown separate heat circuit, so that the Temperature of the heating medium in each of the sub-rooms 21, 22, 23 can be controlled or regulated separately.
- Each of the subspaces 21, 22, 23 is made up of three each Cross section rectangular product channels 35 penetrates the all arranged parallel to each other, as well as straight and are formed without undercuts.
- the length of the Product channels 35 is such that these with the end faces of the middle part 12 of the housing 11 or with the end plates 13, 14 finish flush.
- the width b of the product channels 35 is smaller than the width B of the housing 11, so that between the product channels 35 and the side walls 24, 29 the housing 11 remains a distance.
- the height h of the Product channels 35 is in each of the sub-spaces 21, 22, 23 for taken in the same way, but from one room to another differently.
- the partial space 23 facing is the height h1 of the product channels 35 least, whereas the height h3 of the product channels 35 in the subspace 21 facing the top 17 is largest.
- the height h2 is in the central subspace 22 Product channels 35 between the heights hl and h3. It follows also that the cross-sectional area of the product channels 35 largest in subspace 21, the cross-sectional area of the Product channels 35 in the subspace 23, however, is the smallest.
- a static known per se Mixing element 37 are introduced.
- This the corresponding Height h of the product channel 35 adapted mixing element 37 consists for example of a sheet metal body with protruding beads, Rags or similar and ensures through the increased flow resistance for better mixing of the product.
- the product channels 35 are on by means of the head plates 13, 14 the end faces of the middle part 12 integral with each other connectable so that a continuous product flow is achieved becomes.
- each two Product channels 35 arranged one above the other in the middle part 11 connect with each other.
- Product inlet pipe 39, and on the other head plate 14 opposite in the area of the top 17 of the housing 11 a product outlet pipe 41 is arranged.
- the arrangement or Formation of the overflow channels 38 is such that the Product on a meandering path, i.e. on the longest possible path between the inlet pipe 39 and the Outlet pipe 41 in the middle part 12 through the product channels 35 is directed.
- the heat exchanger 10a shows two overflow channels 38a in the top plate 13a trained, the four arranged one above the other Connect product channels 35 to one another.
- the other head plate 14a has an overflow channel 38b for two Product channels 35, one overflow channel 38c for three Product channels 35 and one overflow channel 38d for four Product channels 35 formed.
- a drain valve 42 which the Drain valve 42 at the level of the bottom of the Product channels 35 is arranged, or even below.
- the heat exchangers 10, 10a, 10b described above work as follows: by means of a in front of the inlet pipe 39 arranged, not shown pump is the product through the inlet pipe 39 into the head plate 13, 13a, 13b promoted. This flows through the delivery pressure of the pump Product in the product channels 35 with heating and increasing pressure the heat exchanger 10, 10a, 10b, the Flow path, i.e. its length by means of the above described training through differently designed Head plates 13, 13a, 13b, 14, 14a, 14b can be influenced.
- each of the subspaces 21, 22, 23 is part of a separate controllable and adjustable heating circuit, it is possible for example, the lowest temperature in the lower subspace 23 to provide, in the upper subspace 21, however, the highest, so that the product is heated gently. This can especially when using heat sensitive additives such as for example, milk may be beneficial. It is of course also possible, bsw. also two of the three Heating circuits to a heating circuit with the same temperature as the Heat transfer medium to summarize.
- the height h3 of the product channels 35 larger in the subspace 21 assigned to the outlet pipe 41 is as the height h1 of the product channels 35 in the Partial space 23 assigned to inlet pipe 38 Volume of the product with increasing temperature and at Transition to the two-phase area (steam and concentrate) otherwise this would increase over the flow path constant high height h of the product channels 35 to one increasing product flow rate.
- the heat exchangers described above can be used Disassembly of the head plates and possibly in the Product channels of existing mixing elements are particularly simple clean as the product channels are straight and are formed without undercuts. Through training of the product channels is the changeover time between two different products or the Recommissioning time or after a break in production relatively low.
