I have a friend in Bulgaria who is a large honey packer, primarily exporting to the EU in barrels and in jars. He has asked me to help him improve his honey filtration and processing to delay granulation. He has asked me to check into ultrasound and vacuum filtration. Does anyone have any knowledge about these filtration techniques? I would be interested in hearing about filtration experience in general, particularly from someone who exports to the EU. He packs high quality linden and acacia honey, so there is a fine balance between good filtration and quality maintenance. thanks, Bill Lord Louisburg, NC :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
