Abstract:
A screw-type dosage unit for producing doses of solid or powdered products, comprising: a frame; a hopper supported on said frame for receiving product to be dosed, said hopper including a first wall and a second wall; an extractor for removing controlled amounts of said product from said hopper; and a stirrer suspended inside said hopper above said extractor for generating vibrations to induce separation, from said first wall and said second wall, of product adhering to said first wall and said second wall, thereby permitting descent of product toward said extractor, said stirrer including a plurality of mutually parallel first rod members each on a different longitudinal axis, all located parallel to and adjacent to said first wall, said stirrer further including a plurality of mutually parallel second rod members each on a different longitudinal axis, all located parallel to and adjacent to said second wall; wherein said stirrer includes a symmetrical tubular structure which is complementary to an internal shape of said hopper, said rod members being mounted to said tubular structure; wherein said first rod members are mounted to a first arm of said tubular structure; said second rod members are mounted to a second arm of said tubular structure; said first rod members and said second rod members all extend parallel to a longitudinal axis of said extractor; and said stirrer is suspended in said hopper so that said first arm and said second arm are parallel to said first wall and said second wall, respectively.
