A roller for a roller press has a core formed with axially opposite outer ends, an axially central passage, and axially spaced and radially extending inlet and outlet passages extending radially at the outer ends from the central passage and opening radially outward at an outer surface of the core. A coolable jacket surrounds the core, and respective manifold rings are mounted on outer ends of the core, cover inlet and outlet passages at the end faces of the jacket. Respective L-shaped connecting passages each have an axially extending segment opening into a respective one of the cooling passages of the jacket and a radially extending segment opening into the respective groove.

A self-optimizing, adaptive product processing system and a corresponding method for grinding and/or crushing cereals and seeds. The grinding and/or crushing takes place in at least one roller mill which includes a roller pair. So as to detect the temperature of the surfaces of the rollers, at least two temperature sensors are disposed on at least one of the rollers. The detected temperature measurement values are used for optimal adjustment and signal generation of the roller setting.

The present invention Production process of nixtamalized maize flour, nixtamalizing the maize fractions separately without producing nejayote, considers the integration of the processes: Semi-humid milling of the maize (fractionated degerm), extruding of the maize endosperm and milling-instant dehydration of the different nixtamalized and extruded maize fractions, has as novelty the way in which the nixtamalization process is carried out and the objective is to provide a nixtamalized maize flour production system that reduces the residues from the maize grain and completely eliminating nejayote production.
