1 2 The invention relates to a radiator for the following. The effect created in this way is only achieved through the Running evaporators, in which the supply and discharge lines achieve rotation, so that the basic idea of this for the heating media at the same time to hold the patent specification in mounting on a motor-driven Serve radiators inside the container. driven wave lies. Such a radiator too In the case of evaporators or devices for input 5 requires a high level of technical effort and is thick, tubular radiators are usually difficult to clean. turns. The tubes are either battery-like. In contrast, the invention has the task of combined into elements or in the form of a radiator with a higher efficiency snakes present. Although such tubular heating. create, with the installation and removal of the radiator bodies have a larger heating surface, the io is simplified and cleaning is to be made easier, thus achieved performance in an unsatisfactory These goals are mentioned in the introduction Ratio. This is mainly because the radiator according to the invention is realized by the thermodynamics resulting movement that the radiator one to the longitudinal axis of the container Liquid causes local irregularities. has inclined casing pipe on which In addition, such tube-like tubes, which are combined in the manner of a battery, are preferably parallel to the outer jacket surface elements or heating coils for cleaning difficult baffle is arranged. This creates a circulation accessible, so that if the material to be evaporated is exposed for a longer period of time, that is, causes a flow, drove a not inconsiderable part of the heating surface through which the efficiency in relation to the has a reduced heat transfer. Heat transfer is favorably influenced. Through the In the case of the known circulation evaporators, the arrangement of a guide plate still has this effect It is also necessary that it be further increased in terms of construction. The use of the in and out The respective built-in radiators take care of the heating medium to carry the heating have to. This requires in a further consequence entbodies is based on the 'consideration, according to the circulation increased construction costs for the entire pre-evaporator as simply and economically as possible direction and, moreover, when carrying out repairs. doors, especially on the radiator, the failure of the front This advantage of simplicity is in the performance at all. Special attention should be paid to a wide variety of products that need to be thickened because of evaporators or devices for thickening. Compared to complicated apparatuses, it has also been placed on the fact that as far as possible cleaning and thus also easy germ-free keeping, sufficient circulation or a circulating movement 30 takes place, especially in the production of medicinal products and similar liquid within the container, with borrowed branches of industry of great importance,

ensure. A container 1 is shown in longitudinal section in the drawing The German patent specification 809548 describes a 35 with the sight glass 2 shown. In this container Immersion evaporator for high performance with a horizontal radiator is built in, which consists of a heating element and crosswise to one another arranged container axis inclined lying jacket tube 3 consists Heating pipes. and is provided with a guide plate 4. Through the The Austrian patent specification 39 503 describes inflow 5, the heating medium, for example steam, a heater for vacuum pans, in which 40 or hot water, is passed into the radiator and the liquid to be evaporated between one another fills the annular space 6 to the outflow 7 either concentric pipes circulates, with the radiators as condensate or cooled liquid leaving the pipes in two sets that cross at right angles. The liquid to be evaporated between the walls of a preferably rectangular liquid is arranged through the inlet 8 into the container vapor chamber. This construction 45 leads and leaves as a Briide at the pipe socket 9 in principle represents a tube bundle heater. With her the container space. The splash plate 10 is used to - in order to generate the circulation process, very complicated arrangements are necessary for the creation of the circulation process, and to prevent the liquid droplets from overturning upwards.
Efficiency is low. In addition, there is the difficulty of cleaning and the very local differences.
Borrowed circulation flow, which is also associated with zone-wise overheating and subcooling. Radiators for circulation evaporators, where is. In the case of the narrow flow cross-sections, the supply and discharge lines for the heating media inevitably lead to congestion and obstructions; at the same time to hold the radiator inside this type of radiator could not be used in the half of the container, therefore known practice. shows that the radiator has a longitudinal The Swiss patent 268 157 describes the axis of the container inclined casing pipe a tube bundle heater, albeit with this (3), on which parallel to the outer the tube bundling is arranged by nesting a lateral surface with a guide plate (4).
