Abstract:

In order to further improve the bulk curing barn automation technology, and achieve the purpose of energy conservation and quality, the test of automatic control device such as inverter and fan automatic control device chain inverter technology was studied. The results showed that variable frequency control technology was beneficial to conserve electricity, especially the treat of self-control and inverter chain speed control according to the dry bulb temperature difference between up and down of the installed room lowered the leaves wind speed in the dry rib period significantly, conserved electricity obviously, and improved the appearance of quality, darkened the color, coordinated the chemical composition of the cured tobacco.
