Rotatory Roaster

Diesel burner is used to heat the air. The heated air is continuously re-circulated, resulting in efficient energy usage. The temperature of the heated air is controlled precisely with an adjustable electronic thermostat.It comes from the Dutch word rooster, meaning “list” or “grid,” a reference to the lined paper used for such lists. (The English word rooster, meaning “a male chicken,” shares a common root.) Roster is used in military contexts to refer to a list of units or soldiers and their duties.
