Abstract

A device and method for filling at least one container with fill product are described. The device includes a product reservoir for accommodating the fill product and a stirring element (for stirring the fill product accommodated in the product reservoir. The depth of immersion of the stirring element in the product reservoir can be varied.

First claim

The invention claimed is:

1. A device for filling at least one container with a fill product, comprising:
a product reservoir that accommodates the fill product;
a stirring element that stirs the fill product accommodated in the product reservoir, wherein the stirring element is displaceable at least between a stirring position, in which the stirring element is immersed in the fill product, and an idle position, in which the stirring element is fully or partly outside the fill product;
means for varying a depth of immersion of the stirring element in the product reservoir; and
a controller operatively associated with the stirring element and configured to dispose the stirring element at least partially outside the fill product during a filling operation and immerse the stirring element in the fill product during an interruption of the filling operation.

2. The device of claim 1 , wherein the stirring element is mounted on a non-rotating part of the device, and is stationary relative to the non-rotating part in a direction of rotation of the product reservoir.

3. The device of claim 1 , further comprising means for controlling a temperature of at least a section of the stirring element.

4. The device of claim 3 , further comprising means for causing the at least a section of the stirring element to be heated and/or cooled.

5. The device of claim 1 , wherein the stirring element comprises at least one vane.

6. The device of claim 5 , wherein an angle of the at least one vane with respect to a vertical axis of rotation of a vane mount is adjustable.

7. The device of claim 1 , further comprising a level sensor that measures a fill product level in the product reservoir.

8. The device of claim 1 , further comprising a temperature sensor that measures a temperature of the fill product in the product reservoir.

9. The device of claim 1 , further comprising at least one filling element in the form of a piston filler that fills at least one container connected to the product reservoir, wherein the filling element rotates with the product reservoir about an axis of rotation of the product reservoir.

10. The device of claim 1 , further comprising a temperature controller configured to control a temperature of an interior of the stirring element.

11. The device of claim 1 , further comprising a product feed valve configured to add the fill product to the product reservoir.

12. The device of claim 1 , wherein the stirring element comprises a vane mount and two vanes.

13. A method for filling the at least one container with the fill product by using the device of claim 1 , comprising:
varying the depth of immersion of the stirring element in the product reservoir depending on an operating state of the device.

14. The method of claim 13 , wherein the depth of immersion is varied automatically between the stirring position and the idle position.

15. A method for filling the at least one container with the fill product by using the device of claim 1 , comprising:
lowering the stirring element to a lower end position from an upper end position into the fill product in the product reservoir during the interruption of the filling operation;
determining whether the fill product covers the stirring element;
adjusting the stirring element to a predetermined desired temperature;
agitating the fill product;
withdrawing the stirring element from the fill product once the filling operation resumes; and
returning the stirring element to the upper end position.

16. The method of claim 15 , further comprising adding the fill product until the fill product covers the stirring element.

17. The method of claim 15 , wherein the stirring element is electrically heatable or coolable.

18. The method of claim 15 , wherein a pneumatic and/or an electrical drive lowers the stirring element, withdraws the stirring element, and returns the stirring element.

19. The method of claim 15 , wherein the upper end position comprises a position that is at least partially outside the fill product.
