title_body: What are the good industrial roasters and grinders ?
upvoted_answer: This questions are hard to answer as the answer may be subjective. Still, as far as I understood that you are mainly after Turkish coffee, why not check industrial coffee producers in Turkey? They have specialized roasters and grinders.
  
  Some keywords in Turkish:
  
  
  "kahve değirmeni" -> "coffee grinder"
  "industrial coffee roaster" -> "kahve kavurma makinası".
