In a pulverising equipment for the production of frozen minced meat, essentially consisting of a pulveriser followed by a malaxator, there is provided means for causing the passage, across the pulverised meat, while it is being stirred in the malaxator, of refrigerated air from which the water vapor has been extracted by condensation. The refrigerated air picks up moisture from the meat, and the moisture (in the form of water vapor) is later condensed out at freezing temperatures as low as -10 to -20 degrees centigrade. This eliminates most of the pathogenic germs from the final product.
