Abstract
Kneader-mixers for mechanical and thermal treatment of products in different state forms, comprising a heatable cylindrical casing and a kneader shaft with heatable disk elements revolving therein and on which are arranged kneading blades scraping the inner wall of the casing. During mixing, these stirring elements cooperate with the hook-like kneading counterelments cleaning the stirrer surfaces and fixed in the casing. In each counterelement an arm forms a kneading gap with the casing wall, while second and third arms clean the disks and shaft. Each radial scraper for each disk element has at least two separate scraping edges, which subdivide the product into two product flows and through the inclined position of the kneading counterelements the scraped product acquires a powerful axial and radial transport component.
