Abstract: A cylindrical freezing drum for a slice ice making machine and method of producing the freezing drum. The freezing drum is supplied with a freezing medium to one side of a drum wall and with a water to an opposite side thereof and cooperates with a scrapper arrangement for successively scrapping off the ice produced on the drum, with the drum being made of steel and provided with an exterior metallic coating. The metallic coating is an aluminum coating applied by an arc spray method. At least one cylindrical side of the steel drum is provided with a corrosion protective metallic coating by applying to the drum surface a layer of aluminum and thereafter turning the drum surface to an accurate cylindrical shape.

Abstract: In a slice-ice producing machine of the type in which water is frozen on a rotating drum and scraped off therefrom in the axial direction by means of slightly inclined scraper knives or edges provided on a stationary knife bar, the knives are arranged in two groups of mutually opposite inclination, whereby the total forces acting on the drum and the knife bar, respectively, are drastically reduced.
