#25 too simple # 20, #21 & #22 too much things in such a small area. This makes it hard to recognize. #18, #19 & #20 A coffee cup has nothing to do with roasting coffee, only drinking. But we only roast.
The Idea of the coffee bag, roasted coffee and coffee tree I like, but in the coffee bag should be green coffee. Try something with a flame like in #23 and try to make it easy to read and recognize.
#65 & #66 are nice, but the grean around the flame should reflect the hybrid part of the roaster. The Hybrid roaster is using the lost heat again and will re-heat it. Hope you can reflect this in the logo.
