Abstract

See full text

An apparatus, system, device, and the like, for a liquid nitrogen dispensing head that may be used in a system for cooling aggregate, such as may be found in a batch plant involved in producing concrete. The dispensing head is positioned over a conveyor belt that conveys aggregate to a mixing apparatus to produce concrete. The head dispenses liquid nitrogen onto the aggregate to cool the aggregate and may include interior chambers separated by one or more baffles. The chambers may reduce the pressure of the liquid nitrogen onto the aggregate in relation to the flow pressure of the liquid nitrogen entering the dispensing head. In another example, an assembly may include sidewalls that extend to the aggregate on either side of the head to form a cooling tunnel through which the aggregate is conveyed and is exposed to the liquid nitrogen being dispensed from the head.
