I have a 25 kg batch coffee roaster that was custom built in Guatemala in 2004. It is a Probat clone made by Logos Mechanicos, a third generation roaster builder.
It has less than 1 hr/week on it is gas and is fully manual. Recently cleaned, lubed, etc. $15,000. Feel free to ask questions.
sidg - thanks for the coaching as well. Been in the coffee business a long time, read the forums, but never posted so good to remember what kind of info needs to be out there.
