Abstract: The invention relates to an apparatus for treatment of foodstuffs for processing and subsequent drying. The apparatus comprises an endless conveyor belt which along part of its length follows a helical path to form a stack, which helical path defines a central space in the stack. The conveyor belt has passages for letting a flow of a gaseous medium both vertically and horizontally through the stack. An end portion of the stack is vertically surrounded by an encapsulation. The apparatus comprises a first means for supplying a first gaseous medium to said central space, and a second means for supplying a second gaseous medium to the encapsulation. The encapsulation is arranged to direct the flow of the second gaseous medium in such a manner that it is passed vertically from said encapsulation to the rest of the stack. The invention also relates to a method for treatment of foodstuffs for processing and subsequent drying.

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.
