Abstract
A system for curing molded concrete products, such as green concrete blocks supported on pallets, wherein a carousel chassis mounting circumferentially spaced carriers, with generally radially extending, vertically spaced shelf members for supporting the products, is disposed for indexing rotary travel in a circular kiln tunnel, the carousel carriers comprising racks with substantially imperforate inner and outer end walls, a substantially imperforate bottom wall, a substantially imperforate radial wall, and a substantially imperforate top wall, but being sidewisely open at at least one side. Circumferentially spaced groups of rack surrounding seals comprising circumferentially spaced resilient wiper blades are mounted to form sealed compartments between the groups as a result of carriers being stopped in indexed position at a series of circumferentially spaced locations in the tunnel, and means is provided for introducing heated air with entrained steam into certain compartment, recirculating it, and entraining added steam in the recirculated flow. At least one carriage mounted for reciprocatory movement on the tunnel floor indexes the carousel chassis which is supported on rollers which adjust in position automatically to accommodate variations in chassis level.
