水稻秸秆营养穴盘热风辅助微波干燥工艺参数优化
Optimization of Technological Parameters for Hot Air-assisted Microwave Drying of Straw-based Nutrient Seedling-planting Bowl Tray
摘要
Abstract
In order to study the optimal process of hot air-assisted microwave drying of straw-based nutrient seedling-growing bowl tray under different conditions,the drying rate and deformation variables of straw-based nutrient seedling-growing bowl tray were used as indicators,and the effects of microwave power,heating temperature and hot air velocity on the hot air-assisted microwave drying process of straw-based nutrient seedling-growing bowl tray were studied by u-sing the response surface,and a quadratic polynomial regression model was established,and the drying process was opti-mized.The results showed that the regression model has high fitting ability,which can better describe the drying process of straw-based nutrient seedling-growing bowl tray.The optimal process parameters of hot air-assisted microwave drying of straw-based nutrient seedling-growing bowl tray were microwave power 1600W,heating temperature 60°C,hot air speed 15m/s,the fastest drying rate was4.015%/min,and the minimum shape variable was1.522cm.This study pro-vides important theoretical support and technical support for promoting the promotion and application of straw-based nu-trient seedling-growing bowl tray.关键词
