Addendum to patent 966

In the previously known cream grippers, the cream container is surrounded by a second container, whereby a cavity is formed into which steam or cooling water can be admitted. The cooling water is used for direct cooling of the cream, while the steam is used for direct heating of the cream is used. There is a swiveling agitator in the cream container, which brine flows through to freeze the cream. Another construction is divided the cavity formed by the two containers. The annular gap between the two container jackets is traversed by brine, while the chamber between the two container bottoms with Steam is charged. The first version has the disadvantage that if there are leaks in the agitator the brine runs into the cream. Furthermore, the agitator cannot be different from that used in the dairy industry stainless V2 a-steel are produced, because this material is not brine-resistant. In the second construction, the cream container can be made from for the same reason cannot be made of V2a steel. One has therefore gone over to this container made of V2 a-plated steel

place. This version has the disadvantage that rust easily forms on the weld seams, which leads to destruction.

The invention is therefore based on the object of creating a cream gripper which has the aforementioned Avoids disadvantages and the inner container does not come into contact with brine, so that he through and can be made from V2a. The solution to the task is thereby indirect

ίο heating and cooling brought about, whereby as Heat or cold carrier a liquid, for example glycerine, is used. As a device the single-cell continuous heater described in German Patent 966 856 is used for dairy industry Purposes.

Then the cream container made of V2a steel hangs in a river steel container; The gap between these two is filled with glycerine in a manner known per se. The glycerine container is surrounded by another mild steel container, creating the heating and cooling room is formed. So glycerine is heated with steam or cooled with water. For the purpose of rapid circulation of the glycerine filling a pump is arranged, which it in countercurrent to the flowing cream. In this way, the cream will get to the required level in the shortest possible time Temperature brought.

The deep-freezing, as well as the heating and pre-cooling, takes place with glycerine. The cooling then happens very quickly, as the glycerine filling circulates during the freezing process will. In order to be able to freeze the circulating glycerine, a cooling unit is arranged in which it is cooled in countercurrent by brine. Because the frozen glycerine gives the cream the heat withdraws, it is possible to freeze the cream in a very short time.

Loss of glycerine cannot occur because all lines are permanently installed. A mix liquids are also excluded.

The drive for the agitator and its supply lines are fixed on the fixed cover part can be laid because its base is fixed. The other part of the lid can be opened.

The drawing represents an embodiment of the

cream gripper according to the invention schematically in section.

The cream container 1 is complete at the bottom and at the sides enclosed by a container 2 for receiving the heat or cold carrier. A circulation pump 3 leads through pipes 4 and one Inlet connection 5 to the container 2, the heat or cold carrier, which via the outlet connection 6 and the return line 7 runs back to the circulation pump 3. By means of a three-way valve 8, a cooling unit 9 can be switched into the pipeline 4.

The container for holding the heat or The coolant is in turn surrounded by a third container 10, which is used to hold steam or cooling water is used. It also has an inlet connection 11 and an outlet connection 12.

A jacket 13 covers the device according to the invention and at the same time provides thermal insulation.

The cream container 1 has an emptying nozzle above 14 a bottom valve 15, which via a connecting rod 16 by means of an above the horizontal outer wall 17 of the container 2 arranged hand wheel 18 can be operated.

On der.horizontalen outer wall 17 of the container 2 an agitator 19 is also fixedly arranged, which with its agitator 20 in the cream container 1 protrudes.

The cream container 1 can be closed by means of a hinged lid 21.

The application and mode of action of the cream gripper according to the invention is as follows: When closed Bottom valve 15 is the cream container ι after opening the lid 21 is filled with cream. In the case of pre-cooling, cooling water is sent through the container 10. The cooling water cools the continuously circulated coolant very quickly, whichever just as quickly releases the cold absorbed into the cream. If the cream is to be heated, so steam is admitted into the container 10; the steam heats the continuously circulated heat transfer medium very quickly and indirectly heats the cream.

When freezing, the steam or cooling water supply switched off. After switching over the three-way valve 8, the coolant is passed through the cooling unit 9 passed so that it is strongly cooled and when passing through the container 2 with cream Removes heat in a very short time.
