Embodiment approach
[0037] As an embodiment of the present invention, the diameter of the through hole 22 close to the inside of the drum 2 is greater than the diameter of the through hole 22 away from the inside of the drum 2 .
[0038] During use, when hot air flows through the through hole 22, because the aperture of the through hole 22 near the inside of the drum 2 is greater than the aperture of the through hole 22 away from the inside of the drum 2, the hot air flows from the end of the through hole 22 near the inside of the drum 2 to the through hole 22 away from the inside of the drum 2. The space at one end inside the drum 2 becomes smaller, and the mass of hot air cannot accumulate in the through hole 22, so that the hot air accelerates to flow through the through hole 22, increasing the flow rate of the hot air through the through hole 22, thereby increasing the hot air flow rate inside the drum 2, And then increase the drying speed of coffee beans; when the hot air flows to the inside ...

The invention belongs to the technical field of preparation of cold extraction coffee, and particularly relates to preparation equipment and a preparation method of cold extraction coffee. The preparation equipment comprises a shell, a motor, a temperature controller, a material taking door, a baking unit and a controller; the controller controls the baking unit; the top of the shell is in an arc shape, and a discharging opening is formed in the middle of the top of the shell; the temperature controller is fixedly connected to one side of the arc-shaped surface of the shell, and the motor is fixedly connected to one side, adjacent to the arc-shaped surface, of the shell; and a roller is arranged at the position, close to the top, in the shell, the arc-shaped outer surface of the roller corresponds to the arc-shaped inner wall of the top of the shell. The roller is matched with the through hole, the motor drives the roller to rotate, the roller drives coffee beans to roll on the arc-shaped inner wall of the roller, and hot air enters the roller through the through hole to dry the coffee beans, so when the coffee beans roll over, hot air is blown to the coffee beans, and the drying uniformity of the coffee beans is improved.
Description
technical field [0001] The invention belongs to the technical field of cold-extracted coffee preparation, in particular to a preparation device and method for cold-extracted coffee. Background technique [0002] Cold brew coffee generally refers to coffee drinks made by grinding roasted coffee beans into powder at room temperature or at a lower temperature. Of course, cold iced coffee is not necessarily cold brewed coffee, the two concepts are different. Because cold brew coffee usually takes longer to extract the substance than traditional hot water. This unique temperature and extended contact time results in a unique sensory and quality profile in the finished beverage, characterized by less bitterness, a smoother mouthfeel and a finer mouthfeel. Cold brewing typically uses room temperature or colder water, allowing for longer periods of time to extract the best flavor and solids from the beans. Factors such as contact time, temperature, degree of roast, grind size, pr...
