Experimental Study of Moisture Content Stability on the Low-speed Pneumatic Drying Process of Cut Stem

Abstract

According to the principle of moisture control at outlet of the cut stem low-speed pneumatic drying equipment of SH23, we studied the relationship between the mixing air valve’s opening and moisture content stability of products and the relationship between the main equipment controllable process parameters and the mixing air valve’s opening by regression analysis. It provides the following basis for improving the moisture content stability by controlling the technological parameters of the equipment, the average value of the mixing air valve’s opening has a significant effect on the stability of moisture content , for each reduction of 1% moisture content in the low-speed pneumatic drying process, it is necessary to turn down the mixing air valve’s opening by about 8.175% and the influence degree of the main control parameters related to the mixing air valve’s opening is arranged.
