The ENARETE hot air generation system is designed and built to produce hot air for use in various drying processes—both for food products (using a heat exchanger) and for agricultural products intended for animal feed, olive pomace, sawdust, etc.
The basic configuration of the system for hot air generation includes the fuel feeder and doser, the heat generator, and the flue gas cleaning and shaping chamber.
Feeder
The feeder consists of a motorized hopper equipped with level sensors, where the fuel is stored. A spring extractor rotates at the base of the hopper, pushing the material toward the feed opening connected to the burner auger.
Burner Auger
The burner auger is made up of two superimposed augers:
The upper auger receives the material from the feeder above and doses it into the lower auger,
The lower auger then transports the fuel to the crucible located inside the combustion chamber.
Both augers are powered by a single gear motor connected via a chain and sprocket system. This setup is designed so that the dosing rate of the upper auger is lower than the transport capacity of the lower auger, to avoid blockages and to prevent any risk of fire from residual material in the loading feeder when the generator is shut down.
Heat Generator
The system can operate with either direct or indirect heat exchange.
