Coffee bean roasting and brewing system

The present invention provides a coffee bean roasting and brewing system, which includes a coffee bean roasting device, a coffee bean brewing device, and a cloud server connected to the coffee bean roasting device and the coffee bean brewing device. The coffee bean roasting device and the coffee bean brewing device may respectively obtain a target roasting curve and the target brewing curve from the cloud server, and the coffee bean roasting device and the coffee bean brewing device can respectively display the actual roasting curve, the target roasting curve and the actual brewing curve and the target brewing curve for operator reference, which is beneficial to ensuring the quality of roasting and brewing. In addition, the roasting information of the coffee bean roasting device and the brewing information of the coffee bean brewing device will be transmitted to the cloud server for storage, thus the cloud server may use the machine learning algorithm to learn the collected roasting information and brewing in
