Problems solved by technology

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, the heat transfer process is slow during the roasting process, and the energy consumption is relatively high
At present, there is no technology and device for roasting coffee using microwaves in the market. This invention proposes a coffee roasting device combined with microwave and electric heating, which is used to realize the processing technology of roasting coffee using microwaves without preheating process, shortening the Baking time, and can adjust the microwave power in real time by monitoring the changes in temperature and humidity, realize the single heating and coupled heating functions of electric heating and microwave, can give full play to the respective advantages of the two heating methods, and improve the baking quality and baking efficiency, reduce production costs, save energy and protect the environment

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 ...
