Abstract

Tobacco granules for heated tobacco products (TGHTPs) were at amorphous state and prone to caking during processing and storage. Hence, it was essential to understand the dynamic caking behavior of TGHTPs for quality control. Moisture sorption isotherms of TGHTPs were of type III and could be well fitted by both DLP and GAB model. Homogeneous caking was observed in TGHTP1 while TGHTP2 ∼ TGHTP4 presented non-homogeneous caking behavior. The basic flow energy (BFE) of TGHTPs increased with rising of relative humidity (RH) and exposure time. BFE value (4093 mJ) of TGHTP3 after 48 h exposure to 90% RH was five times than that of 53% RH (806 mJ). Bound water was found predominant in TGHTPs, the migration of immobilized water to bound state was observed during the moisture uptake process. When the RH was over 56.83 ∼ 58.65% at 25°C, glass transition of TGHTPs was happened from “amorphous glassy” to “amorphous rubbery”.

期刊介绍： The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
