Desorption and sorption isotherms of hemp seeds with dockage

Very few guidelines (such as the isotherm equations – the moisture content of hemp seeds at a given temperature, and relative humidify) exist on aeration, natural air drying, and storage of hemp seeds. If producers and managers used wrong isotherms, spoilage or over drying of the binned hemp seeds might occur during storage. The objectives of this study were to establish the desorption and sorption isotherms of hemp seeds of two common varieties with different percentages of dockage (0, 5, 10, and 15%) by using two most-used methods: static and dynamic methods, and determine the difference of the desorption and absorption isotherms among different hemp varieties. After using the developed isotherms by the producers and managers, the quality of the processed hemp seeds can be improved, so the Canada consumers of the hemp industries can be benefitted from the high quality hemp seeds.
