Study on Microwave Drying Characteristics of Peony Seeds


Abstract: In order to explore a method that can quickly dry peony seeds and dry them, the method is to prolong the storage time and ensure the quality of oil extraction. The peony seeds are tested by microwave drying equipment. The heating time, intermittent time and material layer thickness of microwave drying were selected as experimental factors. The microwave drying characteristics of peony seeds were studied. The drying rate, shelling rate and ripening rate of peony seeds were used as evaluation indexes. The optimum process parameters of peony seed microwave drying were obtained by the integrated balance method.
The results showed that the dehydration process of peony seeds was mainly in the constant speed stage. Different microwave drying parameters had different effects on the microwave drying characteristics of peony seeds. When the drying time was 20 s, the rest time was 60 s, and the material layer thickness was 2 layers. It can obtain a faster drying rate under the premise of ensuring the quality of peony seeds.
