Description

Technical Field

[0001] This utility model relates to the technical field of coffee bean roasting production equipment, specifically to a heat dissipation device for coffee bean roasting production. Background Technology

[0002] Coffee beans are the core raw material for making coffee. Their quality, processing methods, and roasting level directly affect the final flavor of coffee. Coffee bean roasting refers to the process of heating green beans to cause a series of physical and chemical reactions inside and outside the coffee beans, generating a variety of flavors such as acidity, bitterness, and sweetness, forming body and color, and transforming green beans into dark brown beans.

[0003] In existing coffee bean roasting production cooling devices, the cooling pipes are usually straight pipes or direct fan blowing to cool the coffee beans. These methods have poor cooling efficiency and long cooling times. Straight pipe cooling pipes have a small heat exchange area in the same space, resulting in low heat exchange efficiency and long cooling times. Although direct fan blowing can increase airflow, it often only dissipates heat from the surface of the coffee beans, and the internal heat is difficult to dissipate effectively. Due to the low cooling efficiency of straight pipe or direct fan blowing methods, it is often necessary to run for a longer time or consume more energy to achieve the ideal cooling effect. The long and uneven cooling time of straight pipe or direct fan blowing methods can easily lead to a deterioration in the flavor of the coffee beans or the development of a burnt and bitter taste.

[0004] Therefore, it is necessary to invent a heat dissipation device for coffee bean roasting to solve the above problems. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The diagram shows a heat dissipation device for coffee bean roasting production, including a mixing tank 1, a motor 2, a turntable 3, and a main rod 4. The motor 2 is installed in the middle of the bottom surface of the mixing tank 1, and the output end of the motor 2 is connected to the turntable 3. The turntable 3 is located in the middle of the inner bottom surface of the mixing tank 1. A docking plate 301 is provided on the surface of the turntable 3. The cross-sectional diameter of the docking plate 301 is the same as the cross-sectional diameter of the main rod 4. A large docking groove 302 is opened in the middle of the docking plate 301. A docking post 303 that engages with the large docking groove 302 is fixedly installed in the middle of the bottom surface of the main rod 4. The docking plate 301 is fixedly installed on the surface of the turntable 3. Small docking grooves 304 are opened on all four sides of the edge of the docking plate 301. A docking block 305 that engages with the small docking grooves 304 is fixedly provided on all four sides of the bottom surface of the main rod 4. The main rod 4 is located above the turntable 3.

[0026] A stirring rod 5 is provided on the outer side of the main rod 4. The stirring rod 5 is L-shaped and there are four of them. The four stirring rods 5 are respectively installed on the four sides of the outer wall of the turntable 3. Stirring blades 501 are fixedly installed on both sides of the outer wall of the stirring rod 5. Auxiliary rods 6 are provided above the main rod 4. There are four auxiliary rods 6, which are respectively located on the four sides of the top surface of the mixing tank 1. The connecting ends of the four auxiliary rods 6 are provided with fixing posts 601. The fixing posts 601 are fixed to the middle of the top surface of the main rod 4. The other end of the auxiliary rod 6 extends to the edge of the top surface of the mixing tank 1. The extension end 602 of the auxiliary rod 6 is... The mixing tank 1 is F-shaped, with a circular sliding groove 603 on the top. The F-shaped extension end 602 of the auxiliary rod 6 is slidably engaged in the sliding groove 603. The motor 2 drives the turntable 3 to rotate, which in turn drives the main rod 4 to rotate. The rotation of the main rod 4 will drive the four auxiliary rods 6 to rotate, and the extension end 602 slides according to the shape of the sliding groove 603. The mixing tank 1 is double-layered. A cooling pipe 7 is installed in the inner layer of the mixing tank 1. The cooling pipe 7 is a spiral coil type. A temperature controller is installed on one side of the outer wall of the mixing tank 1. The temperature controller is electrically connected to the cooling pipe 7.

[0027] The motor 2, cooling pipe 7 and temperature controller mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0028] The working principle of this practical application is as follows:

[0029] Refer to the instruction manual appendix Figure 1-5 For this type of cooling device used in coffee bean roasting, the mixing tank 1 adopts a double-layer design. A spiral coil cooling pipe 7 is installed in the inner layer. Efficient heat dissipation is achieved through circulating cooling medium. The spiral coil structure of the cooling pipe 7 increases the contact area and improves the heat exchange efficiency, ensuring that the coffee beans cool down quickly. The motor 2 drives the turntable 3 to rotate, which drives the main rod 4, stirring rod 5 and auxiliary rod 6 to rotate synchronously, so as to achieve uniform stirring of coffee beans. The stirring rod 5 has an L-shaped design, with stirring blades 501 fixed on both sides of the outer wall to enhance the stirring effect. The F-shaped extension end 602 of the auxiliary rod 6 slides and engages in the sliding groove 603 at the top of the mixing tank 1 to ensure stirring stability. The temperature controller monitors the temperature inside the mixing tank 1 in real time and controls the flow rate or temperature of the cooling medium in the cooling pipe 7 through electrical connection. When the temperature exceeds the set value, the temperature controller starts the cooling pipe 7 to accelerate heat exchange. When the temperature drops below the set value, the temperature controller adjusts the working state of the cooling pipe 7 to avoid over-cooling.

[0030] When using this device, first ensure that the double-layer structure of the mixing tank 1 is well-sealed and that the cooling pipe 7 is leak-free. Check that the connections of the motor 2, turntable 3, main rod 4, stirring rod 5, and auxiliary rod 6 are secure. Correctly connect the power supply and control signal lines of the temperature controller to the cooling pipe 7. Adjust the temperature controller, set the target temperature range, and turn on the motor 2. The turntable 3 will drive the main rod 4, stirring rod 5, and auxiliary rod 6 to begin stirring. The temperature controller will monitor the temperature inside the mixing tank 1 in real time. When the temperature exceeds the set value, the temperature controller will activate the cooling pipe 7, circulating the cooling medium to lower the temperature. Stirring rod 5 and auxiliary rod 6 continuously stir to ensure even heat dissipation of coffee beans. After the coffee beans have cooled completely, motor 2 is turned off to stop stirring. The temperature controller adjusts the working state of cooling pipe 7 according to the set value to ensure that the coffee beans are cooled to a safe temperature. When it is necessary to remove the coffee beans, the auxiliary rod 6 together with the main rod 4 is lifted upward. At this time, the docking post 303 and docking block 305 at the bottom of the main rod 4 disengage from the large docking groove 302 and small docking groove 304 on the turntable 3, making it easier to remove some parts inside the stirring tank 1 and to conveniently remove the cooled coffee beans.
