  • Patent number: 10349620
    Abstract: A device for forming and cooling an initially hot and therefore flowable melted cheese having (a) a first metallic cooling belt capable of moving in a downstream direction; (b) a counter-pressure roller proximal to the first metallic cooling belt; and (c) a rotatable shaping roller disposed proximal to the first metallic cooling belt downstream of the supply nozzle and upstream from the counter-pressure roller, wherein the rotatable shaping roller has a number of molding cavities formed in the surface, which are separated from one another by separating webs, wherein the separating webs are formed by the remaining surface of the rotatable shaping roller, wherein the rotatable shaping roller is capable of applying a pressure by way of the separating webs onto the cooling belt that results in displacement of the still-hot melted cheese from a region of the separating webs lying thereon, so that shaped bodies of melted cheese released from the molding cavities remain on the first metallic cooling belt for cooling

  • Patent number: 9510620
    Abstract: A method for forming and cooling an initially hot and therefore flowable melted cheese (1), which is applied via a supply nozzle onto a moving metallic cooling belt (3?), wherein individual shaped bodies (6) are formed out of the melted cheese (1) in that a shaping roller (5), which comprises molding cavities (7) located in the surface, impinges upon the cooling belt (3?), wherein a pressure of the shaping roller (5) against the cooling belt (3?) is provided during forming that induces full displacement of the still-hot melted cheese (1) from the region of the separating webs (8) delimiting the individual molding cavities (7) and bearing against the cooling belt (3?), wherein the formed bodies (6) are released from the molding cavities (7) and are cooled by remaining on the moving cooling belt (3?).

  • Patent number: 4833115
    Abstract: A ceramic catalyst carrier has a honeycombed structure which comprises a plurality of elongated parallel preferably square channels and thin, porous walls. The thickness of the walls is between 0.4 mm and 1.2 mm. The open cross-sectional area of the channels is greater than 80% of the total cross-section of the carrier body. Besides an intended low primary porosity, a secondary porosity is produced by an opening material. The pores of the secondary porosity which enlarge the active surface for the catalyst show a selected pore size distribution curve with negative skewness and a modal value ranging from 4,000 nm to 60,000 nm. The total true porosity amounts preferably between 50 and 70 Vol. % of the ceramic, whereby the ratio between total and secondary porosity is in the range of 1:1 to 6:1. By ceramic fibres the mechanical strength of the thin walls of the soft green clot and of the fired porous structure can be improved.
