Abstract
In a method and a corresponding device for producing an extrudate, starting products are introduced into an extrusion container, heated, and homogeneously intermixed by dual asymmetric centrifugation of the extrusion container. The extrusion container is rotated about a primary rotation axis that extends outside the extrusion container, and is simultaneously rotated about a secondary rotation axis that extends through the extrusion container and is situated at an acute angle with respect to the primary rotation axis. Lastly, the intermixed starting products are jointly extruded from the extrusion container. The method and the corresponding device are particularly suitable for processing small and very small substance quantities.
Claims13
A device for producing an extrudate from at least two starting products, at least one of which is a hot-melting starting product, comprising
- an extrusion container for receiving the starting products, having an extrusion opening,
- a heater configured to heat the starting products present in the extrusion container,
- an extruder configured to extrude the starting products, present in the extrusion container, from the extrusion container, and
- a centrifuge for dual asymmetric centrifugation of the extrusion container about a primary rotation axis and a secondary rotation axis, the primary rotation axis extending outside the extrusion container, and the secondary rotation axis extending through the extrusion container and being situated at an acute angle with respect to the primary rotation axis to intermix the starting products,
- wherein the device is configured to extrude the intermixed starting products, present in the extrusion container, from the extrusion container by single-axis centrifugation about the primary rotation axis, with the extrusion opening open.
