As for the Sächsische Malzfabrik (Saxon Malt Factory), it was founded on 29th January 1889 in the industrial district of Plauen in Dresden. Once more I haven't found much about this company. It seems it remained in private hands until the early 1950s but was certainly taken over by the East German authorities afterwards.
Looking at the ghost sign on the tower, I would assume the Sächsische Malzfabrik bought at some point the Bad Sulza malt factory from the brewing business controlled by Robert Deinhardt or, following his death in 1937, his family. However that may be totally wrong.
Unfortunately I haven't been able to decipher what was written between "Malzfabrik" and "Bad Sulza."
