Because the structure of the drying room for drying equipment for wolfberry is relatively complicated, and the state of the airflow tissue distribution of the drying room is also the result of the comprehensive effect of various factors. After the analysis of the cloud map in the airflow tissue in the original drying room, it can be obtained. The speed of the airflow at the position of the inlet ingredients in the drying room is significantly greater, that is, the strength of the airflow is large, which is conducive to the heat transfer of the wolfberry drying process. The material layer, the airflow speed is significantly small, and most of the rotary vortex appear at the location. At the same time, because the air inlet is set at the front end of the drying room, the airflow showed that the length of the drying chamber decreased, and the rear of the drying room also showed more parts of the vortex. Therefore, the impact of the position of the air inlet setting on the distribution of airflow tissue in the drying room is very needed. The use of a reasonable air inlet port installation scheme is of great significance to enhance the uniformity of the distribution of airflow tissue in the drying room and the use of thermal air utilization rate. Essence
For the air inlet position of the air inlet of the air -energy drying equipment, there is a problem with the distribution of airflow tissue in the drying room. In the numerical simulation scheme of the drying room, some designers mainly consider how to make the heat blew into the drying room evenly in the drying room. To maintain the wolfberry layer of various parts, the more uniform wind. Combined with the relevant literature, there are air inlets in the drying room in the simulation scheme.
The air inlet is set along the length of the drying chamber, and 6 inlets are set on each side. In order to prevent the phenomenon of airflow blowing, the air inlet adopts the scheme of the upper and lower staggered settings to determine the inlet of the inlet in the drying room. The accurate position, at the same time, the exhaust port is set at the top of the drying room, and other conditions remain unchanged.
According to analysis, after the air inlet is set on both sides of the drying chamber, there is still a dead end of the airflow tissue in the drying room, but compared with the original inlet setting scheme, there will be a significant improvement. Therefore The status of the organization can be evaluated directly from the speed distribution cloud chart.
