Abstract

After investigation, it was found that there was a temperature difference of 6.09°C before and after the drying area of the small pepper dryer in Guizhou, and the local drying was insufficient. Therefore, this paper starts to optimize and improve the structure of the pepper dryer through simulation analysis, so that the temperature difference between the front and rear of the dryer is within 1.5°C, and the peppers can be dried evenly at the same time. Firstly, this paper studies and analyzes the temperature distribution of the two vertical baffles, and the scheme still has a temperature difference of 3.54°C. Secondly, arc and horizontal slab hybrid optimization scheme is analyzed, and the maximum temperature difference is 1.44°C, so the temperature distribution is very uniform and the temperature difference is small, which can fully meet the actual drying requirements.
