Liquid heater

Hach of German Patent 1 095 785 is a Liquid heater for partial evaporation of the liquid within the heater to increase the concentration of the same known. This heater consists of vertically arranged Flattening, the heating channels and fluid channels with sifting changes according to the cross-flow principle between adjacent plat exhibited. In this case, riser ducts are arranged on the door of the associated heating plate, while evaporator panels are located fall channels are provided on the evaporator plate located behind this heating plate. The heating plate also has an opening connecting the rising and falling channels.

The disadvantage is that an "evaporator plate is required for the riser ducts and for the fall ducts." As a result, the production costs are increased quite considerably, which has the effect of increasing the price of the entire product.

The innovation is based on the clear recognition and elimination of this deficiency. This task will be renewed solved in that on each evaporator plate at least one riser channel for the product to be evaporated

In a further embodiment of the concept of innovation, there is a heater with between the evaporator plates arranged FlacJadeals the passage opening for the Product to be evaporated from each plate above the passage opening for the condensate of each plate.

Another feature of the innovation is the passage opening for the product to be evaporated at least one flat gasket surrounding each evaporator plate a recess is provided through which the to evaporating liquid flows upwards along the evaporator plate in the ascending spur. In addition, there is the passage opening for the mixture of concentrated liquid and vapors from a flat gasket surrounding each evaporator plate zuaindesrfc provided a recess through which the Enter the mixture of the riser channel into the passage opening toire.

It is useful in the flat seal surrounding the passage opening for the heating steam of each heating plate at least one recess is provided through which the Heating steam flows down along the heating plate.

It is advantageous in the passage opening for the condensate a heater board ¹ each uüigebenden Flachdichfcung zumindesrt a recess, via which the con-

condensate into the oil access opening for the condensate of each Heating plate is discharged.

An embodiment of the liquid heater according to the innovation « is explained in more detail below with reference to the drawing. In this show in a purely Scottish way:

Fig. 1 is an isometric representation of the innovation according to the invention Liquid heater

Fig. 2 is a view of an evaporator plate of the innovation Liquid heater

3 shows a view of a heating plate of the liquid heater according to the invention.

As can be seen from the drawing, there is a liquid heater from a stack of evaporator plates P1 and heating plates P2, which are arranged in alternating sequence and in are clamped together in a suitable manner.

Each has an evaporator plate P1 and a heating plate P2 Passage opening Bn 1, 1a for the zn evaporating product, z. B. milk and the like, and barch entry openings 2 »2a for the mixture of concentrated liquid and vapors.

Hit 3, 3a are passage openings for the heating medium in particular 3) ampf denotes »while the condensate over the Durchtrittsöffnxmgen 4, 4a is derived.

Flat seals 5, 5a are arranged between the plates P1, P2. The plates P1, P2 are pressed together with these flat gaskets 5 »5a in such a way that chambers are formed between the individual plates P1, P2 which are connected to the corresponding openings 1, 1a to 4» 4a. , - A -

In the flat seal surrounding the passage opening 1 for the product to be evaporated of each evaporator plate P1 5 at least one recess 5a is provided through which the liquid to be evaporated flows upwards along the evaporator plate in an ascending flow. To this end is on at least one riser channel 6 of each evaporator plate P1 intended for the product to be evaporated.

In which the passage opening 5a surrounding for the heating steam of each hot plate P2 gasket 5 is provided at least one recess 5b through which the heating steam _T along the heating plate P2 by flowing below. Finally is; in which the passage opening for the condensate surrounding 4a of each hot plate P2 gasket 5 at least one recess 5c seen -ROR _t over which the condensate is discharged into the passage opening 4a of each hot plate P2

In addition, the passage opening 2 for aas mixture of concentrated liquid and vapors is one each evaporator plate P1 surrounding flat seal 5 is provided at least one recess 5d through which the mixture vosi riser 6 can enter the passage opening 2.

The mode of action of the newly introduced fluid heater is the following:

The hot medium, for example heating steam, occurs the passage opening 3a into the heating channel of the heating plate P2. By appropriately designing the flat seal 5 in the * area the passage opening 3 of the evaporator plate P1 is the heating steam the way into this plate Pt is blocked.

The steam or the condensate that forms take their ¥ eg along the TpnisTi indicated in FIG. The condensate wirö doing through the opening 5c in the Durchtrittsöff-ί tion 4a, 4 carried out.
