Energy-saving high-efficiency coffee bean baking machine

Abstract

The invention discloses an energy-saving high-efficiency coffee bean baking machine. The energy-saving high-efficiency coffee bean baking machine comprises a base, wherein a baking machine body, a cooling disk and a tail gas box are mounted at the top end of the base; the baking machine body is located between the cooling disk and the tail gas box; an inner cylinder and a gas filtering plate are mounted in the baking machine body; the gas filtering plate is located below the inner cylinder; a thermal mixing cavity and a combustion cavity are separately formed in two sides of the gas filteringplate; a combustor is mounted in the combustion cavity; and a fuel gas pipe is connected between the combustion cavity and the base. According to the energy-saving high-efficiency coffee bean baking machine disclosed by the invention, an exhaust pipe, the tail gas box, a gas return pipe, the thermal mixing cavity, a fan, the gas filtering plate and the combustion cavity are arranged, when the baking machine operates, and fuel gas enters the baking machine body, the fuel gas is combusted through ignition of the combustor, so that expansion combustion is realized in the combustion cavity, and the temperature is quickly raised; after combustion, generated high-temperature gas penetrates through the gas filtering plate to enter the thermal mixing cavity, and then the high-temperature gas is guided to the inner cylinder through the fan to heat and bake coffee beans.

Description

technical field [0001] The invention belongs to the technical field of coffee bean roasting, and in particular relates to an energy-saving and high-efficiency coffee bean roaster. Background technique [0002] Coffee bean roasting is the conversion process of the internal components of coffee beans. A series of chemical changes will occur during the roasting process. Initially, the green coffee beans will lose part of their humidity and turn yellow. During this process, the coffee beans will expand, from The firm, high-density green bean state is transformed into a low-density fluffy state. After this process, the coffee beans will approximately double in size and appear light brown after light roasting. After this stage is completed, the heat will be reduced. , the color of the coffee turns dark. When the preset roasting depth is reached, the coffee beans can be cooled with cold air to stop the roasting process. [0003] But existing coffee bean roasting machine is in the ...
