[0002] Coffee beans refer to the fruit of the plant used to make coffee. Coffee beans need to be roasted during the production process. Only after roasting can the coffee beans be used to make coffee. Baking equipment is needed during the roasting process.

[0003] In the patent application with the authorization publication number CN221576793U and the authorization publication date 2024-08-23, entitled "A Coffee Bean Roasting Device", an air pressure sensor and a plurality of heating rods are installed on the top surface of the roasting cylinder. The coffee beans added to the roasting cylinder can be roasted by arranging the roasting cylinder, the stirring mechanism and the plurality of heating rods. The roasted coffee beans can be quickly cooled by arranging the cooling mechanism and coordinating the stirring mechanism, the solenoid valve, the exhaust pipe and the air pressure sensor. The design of the cooling mechanism can make the jet nozzle rotate while diffusing the cold air, so that the cold air can be quickly diffused to various places inside the roasting cylinder, thereby making the cooling effect of the entire cooling mechanism better;

[0004] However, in actual use of the above device, since several heating rods are fixed on the top surface of the roasting cylinder, the coffee beans are heated unevenly when drying, resulting in poor drying efficiency of the coffee beans, affecting the drying efficiency of the coffee beans, and the air jet nozzle rotates around the center of the rotating tube under the drive of the rotating tube, resulting in a smaller cooling range and lower cooling efficiency.

[0005] So we proposed coffee bean roasting equipment to solve the above problems. Utility Model Content
