8CRYOGENIC GRINDING SYSTEM: • The cryogenic grinding system consists of two main units, namely 1) Precooling unit and 2) Grinding unit The cryogenic precooler is a cooling device made up of a screw conveyor enclosed in a properly insulated barrel and a system to introduce liquid nitrogen into the barrel, thereby providing The cost of nitrogen alone takes over 40% of the cost of cryogenic grinding (Wilczek et al, 2001) For many materials, the supply of cold temperature is not necessarily −1956°C ( Wilczek et al, 2004 )Key issues and challenges in spice grinding ScienceDirect
