Abstract:
The loosening of unpacked strips with FT15 continuous microwave loosening machine was studied,and the loosening rate,changes of structure,temperature,moisture content,moisture uniformity,sensory quality and chemical components of strips before and after microwave loosening were investigated.The results showed that:after microwave loosening,the loosening rate of strips was 94.26% and the moisture content decreased by 0.5%;comparing with loosening by conditioning cylinder alone,large particle content increased by 5% and fines content decreased by 0.3% in microwave+conditioning cylinder treatment,and moisture uniformity also increased.The sensory quality and routine chemical components of strips changed little after microwave loosening,and there was no negative effect to the quality of tobacco leaf.
