Description

GERMAN

The vessels that are used in milk technology to store the milk are already there cooled by placing a tube with relatively large openings around the outside of the upper part of the vessel places and lets water trickle out of the openings along the outer wall of the vessel. Here is the Water consumption relatively high. Because the water flows with pressure from the openings of the cooling ring and should form a continuous water jacket around the container.

On the other hand, double-walled containers are also used for processing the milk, in which the Milk is heated and cooled. Their double wall accommodates the means for heating or cooling. For example, the water used for cooling is fed into the through a connection piece on the floor. Double wall of the container let in and flows through a drain nozzle at the upper edge of the double wall away. The speed of the water along the double wall is understandably only low and its path along the double wall is completely indefinite. The slow flow rate and the indeterminate Flow paths result in a low heat exchange between the hot milk and the cold one Water. As a result, this type of cooling results in a high water consumption because of the long exposure time.

To eliminate these disadvantages, the gap between the double wall is already reduced and In addition, a guide helix is arranged in this gap to create a helical flow path around the wall of the To create inner container. The installation of the guide helix in the narrow gap in the double wall makes but considerable manufacturing difficulties, quite apart from the fact that it is impossible to precisely seal the guide helix in the gap.

The invention is based on the object of the intake of milk, cream and milk or cream-containing Liquids to provide certain containers with a cooling device, which is an essential require lower water consumption because they use the cooling liquid in a relatively thin Let the layer flow along the outer wall of the inner container. The invention solves this problem in that they have a coolant distribution pipe provided with relatively large radial openings arranged in a ring on the upper edge of the milk container and this distributor pipe with a truncated cone surrounds, the inner edge of which rests punctually against the milk container under the distributor pipe and between the contact points forms narrow gaps, from which the coolant in thinner Layer can trickle down from the upper edge of the milk container along its outer wall.

Device for cooling single-walled or multi-walled containers for milk, cream as well as liquids containing milk or cream

Dipl.-Ing. J. Sonnberg, Hildesheim, has been named as the inventor

Here, the water flowing out of the openings is in the channel between the Kagelmantelstump and the container wall, where it forms the water ring standing in the channel. Here is the Braked water flow. The water flows from here much more slowly, and without the line pressure only under the effect of the acceleration of gravity along the container wall.

In addition, the stump of the kegd prevents the spray losses from the cooling water, which are unavoidable, when the cooling water is sprayed against the container at line pressure. Because the truncated cone catches any splashing water and guides it to the container wall.

The drawing serves to explain the concept of the invention. In it shows

Fig. 1 a vertical section through the double wall of a milk or cream container,

Fig. 2 shows a horizontal section through the double wall at the level of each ending with an arrow dash-dotted line of Fig. 1,

Fig. 3 is a view on an enlarged scale of the upper edge of the milk container with the distributor pipe, the wedge-shaped casing sump for sprinkling the outer wall of the container and the trickling down Coolant.

The distributor tube 1, which has the relatively large distributor openings 2 in order to avoid their clogging, is attached to the upper edge of the milk container 3. Its distribution openings are directed against the container wall. The cooling water is fed to this distribution pipe. The truncated cone jacket 4 surrounding the distributor pipe is arranged below the distributor pipe 1. It is punctiform with the ends of the spaced

arranged, wedge-shaped indented beads 5 on the outer wall of the milk container. Between every two adjacent ridge ends, the inner edge of the truncated cone shell and the container wall form a narrow annular gap through which the coolant flows downward in a relatively thin layer along the container wall. The beads give the truncated cone a certain resilience. Therefore, the truncated cone rests tightly on the distributor pipe and on the container wall like a clamping ring. The truncated cone evenly distributes the cooling water flowing out of the large openings in the distributor pipe, and the narrow gaps create a thin film of water on the outer surface of the milk container. The bottom of the outer double wall has the coolant drain 7. Its opening is so high that a mirror is formed on the bottom of the double wall from the cooling water flowing down, which is higher than the bottom of the inner container. As usual, the outer double wall is covered with an insulating layer. It serves to inhibit the heat exchange between the environment and the nutrient liquid in the container when the water cooling is switched off. The coolant trickled in a thin film results in a saving of about 50% of the amount of liquid otherwise required. The speed of the trickling down liquid is many times greater than with the previously known cooling devices and causes a considerable reduction in the cooling times. Patent claims: 1. Device for the cooling of one- or multi-walled containers for milk, cream and milk or cream containing liquids by means of an annularly arranged at the top of the milk container, with radial Ausfiußöffnungen coolant manifold is provided, characterized in that immediately below of the distributor tube (1) a Kegelmantdstumpf (4 ) is arranged, the inner edge of which rests punctually on the milk container and forms narrow gaps between the contact points, from which the coolant can trickle down in a thin layer from the upper edge of the milk container along its outer wall. 2. Apparatus according to claim 1, characterized in that the truncated cone (4) has indented beads, the ridge ends of which bear against the outer wall of the container. 3. Apparatus according to claim 1 and 2, characterized in that the opening of the water drain (7) is mounted so high in the bottom of the outer container that the bottom of the milk container is below the level of the cooling liquid.
