Very popular for low shear mixing, accurate liquid addition, high volume mixing. Examples coffee beans, ground coffee, cereals, animal feeds, pet and aqua feed coating, convection drying. Double mixers solve the transportation problem in larger mixers, over 150 cu. ft. (4250 liters) to achieve high quality. High volume: we have mixers on 36 lb. (.6) bulk density producing 150 metric tonnes per hour. Liquid additions also extremely fast depending upon absorbency.
