What is cold grinding or cryogenic grinding?<\/strong><\/p>

Cold grinding – also known as cryogenic grinding or cryogenic milling – describes the process in which liquid nitrogen is added to the materials to be ground in order to obtain particularly high particle sizes with consistent quality during micronization. This process of ultra-fine grinding (cryogenic grinding) is mainly used for soft, flexible or moist materials, as these are often difficult or impossible to grind. As soon as the ground material is cooled, the material properties change during cold grinding: The material becomes hard and brittle – thus enabling the finest grinding processes. This prevents the ground material from melting and sticking together during micronization. In the case of spices, the aroma and flavors can be lost due to the high temperatures generated by the grinding energy. There is also a risk of oxidation and even dust explosion.<\/p>

Cold grinding is suitable for many materials, for example:<\/strong><\/p>
