  • The journey of coffee beans’ mellow transformation

The journey of coffee beans’ mellow transformation

June 30, 2025

In the world of coffee, every cup of mellow and rich coffee is the amazing result of coffee beans undergoing many “transformations”. The wonderful process from coffee beans to coffee drinks is not only a sublimation of flavor, but also inseparable from the ingenuity of professional coffee equipment. ​
Everything starts with careful screening. High-quality coffee beans are the foundation of mellow coffee. We use high-precision screening equipment to remove defective beans through strict size and density screening to ensure that every coffee bean entering the subsequent links has a full shape and excellent quality, laying the foundation for the mellow taste of coffee. ​
Next, the coffee beans usher in the critical moment of roasting. Roasting is the core of the formation of coffee bean flavor. Our professional coffee roasting equipment is like a “magician” who accurately controls temperature and time. In the range of 180℃ – 220℃, coffee beans undergo Maillard reaction and caramelization reaction, and the internal sugar and protein undergo complex changes, gradually releasing charming aromas such as nuts, chocolate, and flowers and fruits. As the degree of roasting deepens, the coffee beans change from the freshness and brightness of light roasting, to the balanced and mellowness of medium roasting, and then to the richness and intensity of deep roasting. Different roasting curves give coffee beans unique flavors. ​

The journey of coffee beans’ mellow transformation
After the roasted coffee beans are cooled slightly, they enter the grinding stage. The coarseness of the grinding directly affects the coffee extraction effect. Our grinding equipment can accurately adjust the size of the grinding particles according to different extraction methods, such as espresso, hand pouring, French press, etc. Espresso requires extremely fine grinding particles to achieve fast and sufficient extraction; hand pouring prefers medium grinding, allowing the water to slowly flow through the coffee powder to extract rich layers of flavor. ​
Finally, the essence of the coffee beans is released through extraction. Whether it is a high-pressure extraction espresso machine that instantly extracts the rich oil and mellow taste of coffee; or an elegant hand pouring device that slowly awakens the aroma and flavor of coffee with a gentle flow of water, professional extraction equipment can retain the unique charm of coffee beans to the greatest extent and transform it into a cup of intoxicating mellow coffee.​
From coffee beans to coffee drinks, every link is full of professionalism and craftsmanship, and every piece of equipment carries the pursuit of quality. Our commercial coffee equipment is committed to helping you witness the perfect transformation of coffee beans, making every cup of coffee a double enjoyment for your taste buds and soul. Welcome to learn about our coffee equipment and start your journey of mellow coffee!
