Orchard Fan with Two Blades
Working principle in orchard:
In the early spring and late autumn, the air temperature drops because of cool air invasion, especially in the clear & ash-breeze morning and night. When the surface temperature of fruit tree drops under 0ºC, the frost is heavy.
The orchard fan can make the surface temperature of fruit free higher than 0ºC by blowing the wind to mix the high temperature air of high area and the low temperature air around floor, so as to prevent from the frost and low temperature damage.
Working principle in Tea plantation: .
On the clear & ash-breeze night of early spring, it is easy to be happened for late e crown frost. The temperature of low-lying place in tea plantation is lowest, whose frost is heavy. Thlayer temperature of individual tea tree is uneven. The temperature of north-west of upper crown layer is lowest. So it is useful for disturbing the thermal inversion layer near the floor by Tea plantation fan, and blowing the warm air to the lower of crown layer of tea tree to rise the temperature and prevent from the frost. Before the sunrise, the thermal inversion layer gradually vanishes. The temperature near floor is lower than the crown layer of tea tree. At that time, the tea plantation fan can ease the fast temperature rise of crown layer lamina to avoid the stress damage.
