VESSEL ROTARY TYPE MIXING MACHINE AND METHOD FOR PRODUCING GRANULAR DETERGENT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a vessel rotation type mixing machine that can produce a granular detergent composition having good particle dissolution and high particle roundness and a method for producing the granular detergent composition. SOLUTION: This vessel rotation type mixing machine is equipped with an almost horizontal rotary shaft 1a, a cylindrical vessel that rotates around this rotary shaft 1a, a bar type blade 3 that is set in the inner face of the cylindrical vessel 1 and stirs powder 2 in the cylindrical vessel 1 and with a liquid injector 5 for pouring liquid 4 into the cylindrical vessel in which the height of the stirring blade 3 is set to 50% to 90% of the height of the layer of the powder 2 to be put into the vessel 1.
