I also roast 4-5 batches back-to-back and have been cleaning the 
chaff collector on my Quest after every roast using a small shop vac 
dedicated to that purpose. It literally takes about two seconds to 
vacuum the inside area and the mesh strainer. I do this mainly to 
keep the airflow consistent from batch to batch, but it may also help 
reduce the risk of a chaff fire.
