ROTEX system is a fully automated carousel returning equally cured blocks after a pre-set period of time (being the minimum necessary curing time) since they have been produced.
The system concept consists in loading the wet blocks into a single large circular rack that moves step-by-step, in a continuous cycle, to assure the same curing time for all loaded blocks, which can be unloaded after the pre-set curing time.
Indeed, the geometrical position of the block identifies also the exact curing time of the same one.
The circular rack moves inside an insulated prefab tunnel where heated air is suitably circulated and activated to achieve the pre-set conditions.
Various temperature and humidity probes, heaters and fans are located in strategical positions and controlled by a PLC.
Loader and Unloader are also enclosed in the insulating chamber with small holes for inlet/outlet of the tiles. This guarantees a very limited heat leakage.
Advantages: of ROTEX over traditional curing chambers are:
-
Perfect control of curing conditions allowing to reduce number of wooden pallets
-
Simplified logic as only the hydraulic indexer of the carousel has to be controlled (4 limit switches)
-
Much less machines reflecting both in a reduced cost and in better efficiency
-
Less energy required for heating a single compact tunnel and for energizing the machines
-
Less maintenance required due to the minimized number of machines
-
Savings on civil works as less area is needed and just a flat floor to erect the prefab tunnel
