ABSTRACT: In order to explore a method of drying peony seeds quickly and with better quality after drying, in order to prolong the storage time and ensure the quality of pressed oil, microwave drying experiments were carried out on Peony seeds.
The microwave drying characteristics of peony seeds were studied by choosing heating time, intermittent time and material layer thickness of microwave drying equipment as experimental factors. The drying rate, shell bursting rate and ripening rate of peony seeds were taken as evaluation indexes. Orthogonal experiments were carried out on Peony seeds. The optimum technological parameters of microwave drying of peony seeds were obtained by comprehensive balance method.
The results showed that the water loss process of peony seeds was mainly at the constant speed stage. Different microwave drying parameters had different effects on the microwave drying characteristics of peony. When the drying time was 20 seconds and the drying time was 60 seconds, and the material layer thickness was 2 layers, a faster drying rate could be obtained under the premise of guaranteeing the quality of peony.
