Coating With Honey: A Study With Model Solids

Simulation studies on coating of steel balls with honey as well as the rheological measurements were carried out at different moisture contents (20.3–37.7%, dry basis), and temperatures (5–80C). The coating characteristics of honey were judged by the thickness of honey layer, and by the proposed index, dimensionless uptake. Honey possesses extremely high viscosity at low temperatures and/or at low moisture contents. The sensitivity of honey viscosity with temperature was determined by using Arrhenius equation. Enhanced values of dimensionless uptake and thickness were obtained at low temperature‐low moisture combinations. Viscosity of honey for easy handling and coating is in the neighborhood of 103 mPas corresponding to a temperature of 50C.
