VORRICHTUNG SOWIE VERFAHREN ZUR PHYSIKALISCHEN BEHANDLUNG VON MATERIALIEN ZUR REDUZIERUNG DES MIKROBENGEHALTES

摘要

A manipulating apparatus (10) receives a plurality of previously frozen pieces of foodstuffs or workpieces (23) and physically manipulates or stresses the workpieces while they remain at least partially in a frozen state. The physical manipulation causes relative movement between various points within the volume of the workpieces (23) and kills microbes within the foodstuff. The treatment process may include physically manipulating the foodstuff in multiple cycles to enhance microbe kill.
