Description of the Related Art FIG. 3 is a view showing an outline of an apparatus for producing ready-mixed concrete, in which aggregates such as sand and gravel are separated into fine aggregates (sand) and coarse aggregates (gravel). The aggregate is cooled by the aggregate cooling device 1, and the coarse aggregate is cooled by the coarse aggregate cooling device 2, and the cooled fine aggregate and the coarse aggregate are respectively transported by the transport devices 3.
The raw material is conveyed to a batcher plant 5 by a kneader 4, and the cooled fine bone and coarse aggregate are kneaded with cement, water, an admixture, and the like to produce ready-mixed concrete. As disclosed in, for example, JP-A-8-112812, the fine aggregate cooling device 1 is provided with a low-temperature cooling air supply device 8A from an air supply port 7 provided near a lower end portion of a tower-shaped cooling device main body 6. A low-humidity air flow is supplied to the cooling device main body 2, and fine aggregate sent from the transport device 9 is supplied from an aggregate input popper 10 provided at the upper end of the cooling device main body 2, and the cooling is performed. The fine aggregate is cooled by the evaporative cooling method while being dispersed and collided by the dispersing device 11 provided in the aggregate falling passage of the apparatus main body 2 (see FIG. 1). In the evaporative cooling method, a low-temperature, low-humidity air stream is sent to the aggregate to vaporize the moisture (surface water) adhering to the surface of the aggregate, and the surface water is vaporized from the aggregate when the surface water is vaporized. The above aggregate is cooled by removing heat. Further, the coarse aggregate cooling device 2 includes a water spraying device 13 above the coarse aggregate storage bottle 12 and a cold air supply device 8B from the lower portion because the coarse aggregate has good air permeability.
A structure that supplies a low-temperature, low-humidity airflow is used (see FIG. 1). Coarse aggregate cooling device 2
In this method, surface water is attached to the surface of the coarse aggregate by spraying water, and after spraying, an air flow is sent from the lower part of the storage bottle 12, and the surface water is vaporized by the air flow to cool the coarse aggregate. The cold air supply devices 8A and 8B are independently controlled according to the required supply amount of fine aggregate or coarse aggregate.
Normally, the aggregate cooling devices 1 and 2 stop cooling the aggregate except for the ready concrete production time, and the cool air supply device 8
A and 8B also stopped blowing.

When A and 8B are provided, not only does the blower facility become larger, but also the operating efficiency of each of the cool air supply devices 8A and 8B is low and the facility efficiency is poor. Further, since the coarse aggregate has a larger heat capacity than the fine aggregate, the target cooling temperature of the coarse aggregate is higher than the target cooling temperature of the fine aggregate, and the pre-cooling time can be short.
The operation rate of B was even lower.
