I have noticed that you roast on 5 kg one too and that is also "great". I believe the 5 kg toper should be really good, but how is cafemino great? It can not separate the chaff and the beans come out full of it in the cooling drum. The machine can not simply cool the beans and my one (I dont use it at all after a few trials) is not exception. On my email they answered that "after my letter they had done trials and to their surprise it turnd out they had done some mistakes when making this model and now they would work on this and come back with solution". I got the solution too -- "We can give you a stronger fan motor but it will result in longer roasting time per batch". I myself doubt that it will also grab the roasted beans to the chaff collector. And after all when you put 1 kg load it can not do it earlier then 30 minutes even now and if prolonged you can imagine the rest. When there is from 500g to 1 kg load the beans are usually stuck in glass window and they dont roll with other beans, so when the batch is already roasted you still see only green beans in the glass, the huge sampler is located too high and it permanently fails to get any beans out till it is really at the end of roasting and the bean size is increased very much, that time you have chance to grab some.
So I doubt your experience that you "roast with the Toper's Cafemino - Electric with no issues. It's great! Roasts 2lbs per batch every 15 minutes depending on the temperature and roast."
Good luck!
Ok, I have 60 kg Toper and that is good.
