<p>The cooling system comprises a vessel (1) housing an evaporator (2) connected to a refrigeration unit (3) through which a refrigerating fluid flows. A pressure-sensitive device (15) limits the rotation of a stirrer (10), connected to the low pressure circuit (8) between the expansion unit (6) and the compressor (4) of the refrigeration unit (3), when the value of the low pressure exceeds a predetermined value corresponding to an average milk temperature of more than 20 DEG C. <IMAGE></p> |
