Description

technical field [0001] The invention relates to a combined microwave and electric heating coffee roasting device, which belongs to the technical field of agricultural product processing. Background technique [0002] Due to its technical advantages of fast and convenient heating, clean and environmentally friendly energy, high efficiency and low energy consumption, the application research of microwave in agricultural product processing has always attracted much attention. Microwave baking can penetrate deep into the material instantly without heat transfer process, and use the higher temperature generated by microwave to directly achieve the processing purpose of improving the flavor and structure of the material. At present, the coffee roasting process on the market mostly uses electric heating as the heating method for roasting green coffee beans, and the roasting chamber needs to be preheated in advance. During the roasting process, the heat transfer process is slow and ...
