摘要： PROBLEM TO BE SOLVED: To make a cooling unit smaller and simpler, achieve a more accurate temperature control for precooling and realize an easier method of control.
SOLUTION: The method of control for precooling of casting concrete comprises pouring ready-mixed concrete into the drum 2 of the truck agitator 1, spraying a liquified gas through liquified gas spray nozzle 3 in the drum 2 while agitating, calculating the relationship between the temperature drop of the ready-mixed concrete and the amount of the sprayed liquified gas by adjusting the amount of the spray, setting the surface temperature detection spots 4, 4, ... on more than one spots on the surface of the drum 2 for detecting the temperatures corresponding to the temperature of the ready-mixed concrete in the drum 2 to enable a convertive determination of the temperature of the ready-mixed concrete from the surface temperatures of the surface temperature detection spots 4, 4, ... measured by non-contact thermometers and controlling the amount of the liquified gas sprayed into the drum 2 from the calculated values and the measured values of the surface temperatures to obtain a desired precooling temperature.
