Path analysis of leaf temperature and curing factors of accumulation of loose leaf cured tobacco in curing process
To study the influence of some cured factors on leaf temperature in the curing process,the leaf temperature,wind speed,wind pressure,dry bulb temperature,wet bulb temperature and relative humidity were monitored by multi-parameter real-time monitor of flue-curing tobacco and temperature and humidity auto-controlled apparatus in curing process.The results showed that there were four stages about the leaf temperature in the curing process:preheated warming stage,stably warming stage,slowly warming stage and quickly warming stage.There were different main factors in the four stages.The main factors included dry bulb and wind pressure in the preheated warming stage; and the main factors were relative humidity and air pressure in stably warming stage; but the main factors were the dry bulb temperature and relative humidity in slow warming stage,however,the main factors were dry bulb temperature and relative humidity,next were wind speed and wind pressure in quickly warming stage.The reason for tobacco leaf temperature changing was the external environment and internal physiological interaction,so the leaf temperature could be controlled to improve the quality of tobacco curing comparison in loose leaf accumulation curing process.
