Design of the Rotation-Cage-Type Drier of Penetrating Hot Air
摘要
Abstract
The way to design the rotation-cage-type drier of penetrating hot air to dry some friable grainy material was discussed in this paper. Loaded with material, the rotation of the cage can slowly and continuously change the position of the internal and external material layers under the gravity and internal fraction. Hot air passes through the layers and dries the material evenly. The influence of the wind outlets of the all opened, partial barrier and the all barrier on the distribution of the airflow velocity was compared in this paper. Experiments have shown that the airflow velocity distribution of the all barrier at the wind outlet is more even than those of the other two. Using a hot air of 125℃ and a flow quantity of 8 511m3/h, a two-hour trial production with split walnuts was performed and a high quality product of even dryness with the moisture content reduced from 30% to 3% and a small broken fraction were obtained. That can meet the requirement of production.关键词
