Caking of crystals: Characterization, mechanisms and prevention
网页2018年9月1日 · Based on particle and crystal engineering, prevention of crystals caking is discussed through controlling ambient conditions (relative humidity, temperature, liquids screening, and pressure) and improving anticaking property of crystals (particles size, particles shape, impurity, and anticaking agent).
Caking of crystals: Characterization, mechanisms and prevention
网页2018年9月1日 · Mechanisms. Generally, caking of crystals occurs during the absorption and desorption of moisture content, e.g. storage and transport under high humidity, drying process with alcohol or other rinsing liquids on the particles surfaces, etc. The liquid content plays an important role in the caking process [51].
Multiscale Study on the Mechanism of a Bio-Based Anticaking …
网页2020年12月3日 · Figure 1. Caked salt. For NaCl, the most widely used anticaking agent is based on ferrocyanide or [Fe (CN)6] −4. (2,4,5) The sodium salt in its hydrous form is also known as yellow prussiate of soda (YPS). To be effective, only 2.5 ppm (equivalent to 2.5 mg/kg) of YPS is required in salt.
网页The polymorphism, phase tran-sitions, chemistry reactions, nucleation and growth theory are consid-ered to discuss the possible research points. Based on particle and crystal engineering, and the idea of“quality by design ”, the factors for caking prevention are summarized systematically. 2. Characterization.
Caking of crystals: Characterization, mechanisms and prevention
网页2017年4月25日 · A multiscale study of the anticaking effect of the bio-based additive Fe-mTA, a metal–organic complex of iron (III) and meso-tartrate, shows that roughness produces a surface roughness at the micron scale, thus preventing the caking phenomenon and, in addition, preventing adhesion of the crystals to solid substrates. Expand.
Anticaking Agents - Chemistry of Food Additives and Preservatives ...
网页Summary. This chapter contains sections titled: The caking phenomena. Mechanisms of caking. Classification of anticaking agents. Anticaking agents in use. References.
Caking of crystals: Characterization, mechanisms and prevention
网页2017年4月1日 · Mechanisms. Caking process is organized into three stages: moisture sorption, then liquid bridge, and finally crystal bridge.
Multiscale Study on the Mechanism of a Bio-Based Anticaking
网页2020年12月3日 · Caking constitutes a major problem for the flowability, transport, packaging, and consumption of hygroscopic granular crystalline materials such as salt. Sodium chloride is the most abundant salt on the earth and known to form strong lumps, mainly due to cycles of water uptake and water evaporation. ….
Caking of crystals: Characterization, mechanisms and prevention
网页TL;DR: In this paper, the authors consider particle issues and technology in a crystallization view (crystallization science and engineering) and discuss prevention of crystals caking through controlling ambient conditions (relative humidity, temperature, liquids screening, and pressure) and improving anticaking property of crystals (particles s...
Caking of crystals: Characterization, mechanisms and prevention
网页Caking process is organized into three stages: moisture sorption, then liquid bridge, and finally crystal bridge. The mechanisms are reconsidered with recent studies (e.g. mass transfer, adhesion effect of liquid bridge, kinetic of crystal caking) and crystallization science (e.g. nucleation and growth theory, polymorphism, and phase transition).
