Abstract (en)
[origin: EP0363860A2] The invention relates to a method and an apparatus for the simultaneous grinding and cooling of solid substances by means of a cutting mixer. The cutting mixer is evacuated in at least one vacuum stage, and refrigerated liquefied gas is introduced into the cutting mixer in at least one cooling stage. In order to optimise the method, it is proposed to draw off the waste gas arising during the cooling stage. A waste gas valve 12 is to this end advantageously installed which is closed before the end of the vacuum stage and opens after the latter is complete in order to draw off the waste gas arising during the cooling. <IMAGE>
