Tunnel oven for roasting coffee beans, peanuts, etc. - with a forced draught of hot air
Реферат: In a tunnel oven, the coffee beans or peanuts rest on the moving grill without need of turning or tumbling, as in a rotary roaster, so they suffer less damage. Moreover, the heating in a tunnel oven is very uniform. The oven is made in units of 1m dimension. In the ceiling of each unit is an electric heating element and an electric fan, which blows directly on the elements and sens the heat, through ducts at the side of the oven, to the grill, which is underneath the fan. The passage from the ducts to the main body of the oven is regulated. The hot air recirculates.
