After heating the material (28), a vacuum is generated in the gastight space. The material is stirred using a heated tool (32), and is flushed using inert gas, typically nitrogen, which can be injected into the material. The level to which the induction vessel (26) is filled with the material can be set dependent on the amount of the volatile ingredients, so that it remains nearly constant after they have been discharged. |
