When it is used, it needs to be turned on after the fire is ignited, so that the drum can be evenly heated, and a small amount of Mars can be beaten in the cylinder. Start the conveyor belt to send the leaves, according to the temperature indication to cast the leaves, different grades of fresh leaves or fresh leaves with different water content require different temperatures, the inlet temperature should be controlled at (120 ~ 130) °C, can pass the green machine conveyor belt The upper leaf device is used to control the amount of leaf to be planted, from fresh leaves to leaves for about 1, 5 to 2 minutes. The water content of the green leaves is controlled at about 60%. The moderate sign of greening is dark green in the leaves.
