Immersion blender

An immersion blender is basically a machine with 2 rotating Blades on the end which are immersed into what is being blended, such as a soup. If I had a meat immersion blender which was then used in blending a hot, pareve soup including onions, does that make everything pareve which was used into fleishig? Thanks

Was the blender used for meat within 24 hours of its use for the pareve soup?

Does the questioner follow Ashkenazi or Sephardic customs?

Not been used 24 hours before and ashkenazi, thanks

Its still pareve
