Through the experiments,the drying constant has been comfirmed in this paper,and the heat and mass transfer model of deep fixed-bed for styrene butadiene rubber(SBR) is established.

The dimensional analysis method was employed to build an empirical equation of the drying constant k,which are function of drying temperature,sample quality,stem length,medium velocity and initial moisture content,and the functional relation between the temperature characteristic coefficient n and drying temperature was obtained.

Experimental research on decreasing the drying rate differences between stems and leaves of the alfalfa;

Effect of ultrasonic pretreatment on sludge drying rate

BP neural network prediction of the effects of drying rate of fruits and vegetables pretreated by high-pulsed electric field

Change of moisture content(MC) and drying velocity characteristics of wood flakes,the influence of microwave power and flake form on the change properties of MC and drying velocity were studied by experiments with regular microwave drying,air oven drying and combined drying of microwave pretreatment and air oven drying.

Electronic moisture analyzer is used to study the dehydration of alfalfa during drying temperature 80 -230℃ and analyze other factors which influence on drying velocity of stems, leaves and stems with leaves attached and the shrinkage of stems and leaves.

The electronic moisture analyzer and the constant temperature and humidity equipments were used to study the influences of humidity to alfalfa drying velocity.
