摘  要:
为解决气体射流冲击干燥机装载量低、喷嘴直径与喷嘴出口形状更换困难等问题,设计了一种脉动式气体射流冲击干燥机。该干燥机可根据不同物料调整风温、风速、料架转速及喷嘴直径与出口形状。干燥过程中物料受脉动高速热气流的冲击,有利于物料内部水分向外迁移。以加工番茄为例进行了干燥机的性能验证试验,结果表明:脉动式气体射流冲击干燥与气体射流冲击干燥相比装载量和去水强度得到了较大的提高。

摘  要:
A pulsed air-impingement dryer was designed with large processing capacity,convenient to replace the size and shape of the nozzle exit compared to conventional air-impingement dryer.The machine could adjust air temperature,wind speed,rotary speed of materiel shelf,nozzle diameter and structure according to different materials properties.Material was received the pulsed impact of high-speed hot air,which contributed to outward migration of moisture within the material.Tomato was adopted to test the performance of pulsed air-impingement dryer.The results showed that the dehydration intensity and processing capacity of pulsed air-impingement dryer was improved than the conventional air-impingement dryer.
