11 Feb Stone grind slowly at low temperature
True. From a research conducted by Professor Giovanni Dinelli of the University of Bologna, full professor at the department of agricultural sciences and technologies, it has been shown that stone grinding plants can be of various models and types, usually when they do not exceed 80 turns per minute, they do not overheat the flour reaching a maximum of 45 ° C, unlike the cylinder grinding where the flour can reach temperatures that reach 90 ° C.
Obviously, there may be cases in which the companies grind stone with the sole objective of maintaining high quantities, in that case they use mills that exceed 200 rpm and the product can increase the temperature exceeding 65 ° C.
It goes without saying, that the higher the temperatures of the product, the greater the nutrients that will inevitably be lost.
