A method of measuring or dosing dry mixture ingredients includes providing separate flow channels for ingredients. The flow channels including at least a first flow channel and a second flow channel configured such that the first flow channel is at least partially disposed around the second flow channel. The first flow channel may include an outer concentric metering screw and the second flow channel may include an inner concentric metering screw. The method further including providing a first material to the first flow channel and a second material to a second flow channel, wherein one of the first and second materials comprises a single dry ingredient and the other of the first and second material comprises multiple dry ingredients. The materials are advanced through the channels to a shared exit where a mixing zone is provided.
