In order to deliver products flowable and dosable, the conversion of powder or fiber mixtures is necessary. The most effective process here is granulation or compacting. At JRS, only the recipe components are compacted between press rolls - without the addition of foreign substances - and converted into granules of any grain size and degree of compaction by means of crushing and screening equipment. The process usually leads to a temperature increase of 20 - 30°C only for a short time. By means of special additional equipment, even very hygroscopic or temperature-sensitive products can be processed.

The technology and world market leader is the only service provider in Germany to offer its customers certified compacting services with food standard - FSSC 22000, HACCP - in quantities of o more than 100 tons per month.
