Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to an automatic coffee bean roasting degree detection and sorting machine. Background Technology

[0002] Coffee, a globally popular beverage, is heavily influenced by the roasting level of coffee beans. The roasting level determines key characteristics such as aroma, acidity, and bitterness. Different roasting levels offer distinctly different taste experiences, from the fresh and bright flavor of light roasts to the rich and full-bodied taste of dark roasts, satisfying diverse consumer preferences. In the coffee production industry, accurate testing and sorting of coffee beans at different roasting levels are crucial to ensuring consistent and stable product quality. This not only helps improve the overall quality of coffee products and enhance brand competitiveness but also satisfies the personalized taste preferences of different consumers, improving market adaptability.

[0003] However, traditional coffee bean roasting degree detection and sorting technologies have many drawbacks. In the past, most of the detection relied on manual methods, with workers judging the roasting degree by observing the color and smell of the coffee beans, or even by chewing them based on experience. This method is inefficient, labor-intensive, and the results are easily affected by the subjective factors of the workers. Different workers have different judgment standards, making it difficult to guarantee the accuracy and consistency of the detection. In the sorting stage, manual operation cannot quickly and accurately separate coffee beans of different roasting degrees, resulting in limited production efficiency. This not only increases production costs but may also affect consumer satisfaction with coffee products due to inconsistent quality, hindering the standardization and large-scale development of the coffee industry. To address this, we propose an automatic coffee bean roasting degree detection and sorting machine. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 An automatic coffee bean roasting degree detection and sorting machine includes a base plate 1. A set of parallel fixed seats 2 are fixedly installed on the top of the base plate 1. A support rod 3 is rotatably installed on the top of one fixed seat 2. A conveying frame 4 is rotatably connected to the top of the other fixed seat 2 and the support rod 3. A feed hopper 5 is fixedly installed on the top of the conveying frame 4. A discharge hopper 11 is fixedly installed at the other end of the conveying frame 4. A conveying structure is provided inside the conveying frame 4. A motor structure is provided on the side of the conveying frame 4. A support frame 13 is fixedly installed on the side of the base plate 1. A vibration structure is provided on the top of the support frame 13. A connecting slide 16 is fixedly connected to the top of the vibration structure. A coffee bean sorting module 17 is fixedly installed at the other end of the connecting slide 16. A detection structure is provided on the top of the coffee bean sorting module 17. A coffee bean collection structure is provided at the bottom of the coffee bean sorting module 17.

[0025] Furthermore, the motor structure includes a conveyor motor 6 and a gearbox 7. The gearbox 7 is fixedly installed on the outside of the conveyor frame 4, and the conveyor motor 6 is fixedly installed on the side of the gearbox 7. The output shaft of the conveyor motor 6 is fixedly connected to the gear inside the gearbox 7. The conveyor motor 6 in the motor structure is a type of motor with stable speed and sufficient torque output, such as an AC asynchronous motor or a DC brushless motor. The AC asynchronous motor has lower cost and reliable operation, and can meet the power requirements of coffee bean conveying under general production scale. The DC brushless motor has higher efficiency and more precise speed control performance, and is suitable for production scenarios with high requirements for conveying accuracy. In addition to transmitting power and changing speed, the gearbox 7 can also reduce the speed and increase the torque of the motor output power, so that the rotation of the roller 8 is more stable and powerful, ensuring that the conveyor belt 9 can stably convey coffee beans and avoid jamming or uneven conveying speed due to insufficient power.

[0026] The conveying structure includes rollers 8, conveyor belts 9, and partitions 10. Rollers 8 are rotatably mounted at both ends of the conveying frame 4. One end of the roller 8 is fixedly connected to the gearbox 7 on the outside of the conveying frame 4. The outer side of the roller 8 is connected to the conveyor belt 9. Multiple sets of partitions 10 are fixedly installed on the surface of the conveyor belt 9 in an equidistant manner. The roller 8 is made of high-strength, wear-resistant metal material, such as stainless steel or alloy steel, to withstand the weight of the coffee beans and the friction of the conveyor belt 9, preventing deformation or wear during long-term use. The conveyor belt 9 is made of rubber or polyurethane material with good flexibility and wear resistance, ensuring that it will not easily break or be damaged during the conveying process. Moreover, the surface of the conveyor belt 9 is specially treated to increase the friction between it and the coffee beans, preventing the coffee beans from sliding during the conveying process and ensuring the stability of the conveying. The height and spacing of the partitions 10 are designed according to the average size of the coffee beans, which can effectively separate the coffee beans without squeezing or damaging them. At the same time, the material of the partitions 10 also has a certain degree of flexibility to prevent damage to the coffee beans or the conveyor belt 9 during collisions.

[0027] Furthermore, the vibration structure includes a vibratory plate 12, a support plate 14, and a support block 15. The support plate 14 is fixedly installed on the top side of the support frame 13, and the support block 15 is fixedly installed on the top of the support plate 14. The vibratory plate 12 is fixedly installed at the top center of the support frame 13, and one side of the top of the vibratory plate 12 is fixedly installed on the top of the support block 15. A connecting slide 16 is fixedly installed at the end face of the vibratory plate 12. The vibratory plate 12 generates vibration through electromagnetic vibration or eccentric wheel vibration. The electromagnetic vibration type vibratory plate generates periodic electromagnetic force by energizing and de-energizing an electromagnetic coil, causing the vibratory plate 12 to vibrate. The eccentric wheel vibration type vibratory plate generates vibration by rotating an eccentric wheel driven by a motor. The vibration of the vibratory feeder 12 is caused by the force of the vibration. The support plate 14 and support block 15 not only support the vibratory feeder 12, but also buffer and adjust the vibration. The materials are usually selected with certain elasticity and damping, such as rubber or polyurethane, so as to reduce the impact of vibration on other parts of the equipment, and at the same time ensure that the vibration amplitude and frequency of the vibratory feeder 12 are stable within a suitable range, so that the coffee beans can be evenly dispersed and lined up on the connecting slide 16. In addition, the vibration frequency and amplitude of the vibratory feeder 12 can be adjusted according to the characteristics of the coffee beans and production needs. For example, for coffee beans with larger particles or stronger stickiness, the vibration frequency and amplitude can be appropriately increased to improve the dispersion effect.

[0028] Furthermore, the detection structure includes a detector 18 and an indicator light 19. The top of the coffee bean sorting module 17 has multiple sets of equidistant, linearly distributed slots. The detector 18 is fixedly installed in each slot, and the indicator light 19 is fixedly installed on top of the detector 18. The detector 18 can employ various detection technologies, such as near-infrared spectroscopy and machine vision. Near-infrared spectroscopy analyzes the absorption and reflection characteristics of coffee beans to near-infrared light to accurately obtain information on the internal chemical composition of the coffee beans, thereby determining their roasting degree. Machine vision uses a high-definition camera to capture images of the coffee beans and analyzes their color, shape, and texture through image processing algorithms to accurately determine the roasting degree. The indicator light 19 uses LEDs of different colors; for example, green indicates a satisfactory roasting degree, and red indicates an unsatisfactory degree, allowing operators to intuitively understand the detection results. Moreover, the brightness and flashing frequency of the indicator light 19 can be set. In bright production environments, the brightness of the indicator light can be increased to ensure that operators can clearly see the detection results. When it is necessary to attract the operator's attention, the indicator light can be set to flash rapidly.

[0029] Furthermore, the coffee bean collection structure includes coffee bean outlets 20 and coffee bean collection boxes 21. The bottom of the coffee bean sorting module 17 has an outlet, and multiple sets of coffee bean outlets 20 are fixedly installed at the bottom of the coffee bean sorting module 17. A coffee bean collection box 21 is located at the bottom of each coffee bean outlet 20, and a square groove corresponding to the coffee bean outlet 20 is formed on the top of the coffee bean collection box 21. The size and number of coffee bean outlets 20 are designed according to the coffee bean output and sorting accuracy. For production lines with higher output, the number of coffee bean outlets 20 can be increased, and the outlet size can be appropriately enlarged to improve collection efficiency. The coffee bean collection box 21... 1. Typically, a movable design is adopted, which makes it convenient to replace the coffee beans in time when they are full, without affecting the normal operation of the equipment. The material of the collection box 21 is food-grade plastic or metal to ensure that it will not affect the quality of the coffee beans. In addition, some dividers can be set inside the collection box 21 to further separate coffee beans of different batches or different roasting levels for easy subsequent management and processing. Some auxiliary devices, such as guide plates or buffer pads, can also be installed between the coffee bean outlet 20 and the collection box 21 to allow the coffee beans to fall into the collection box 21 more smoothly and avoid damage caused by splashing or collision during the fall.

[0052] Working principle: Coffee beans are poured into the conveyor frame 4 through the feed hopper 5. The conveyor motor 6 starts, and the output shaft drives the gears in the gearbox 7 to rotate. The gearbox 7 is fixed on the outside of the conveyor frame 4. Its power is transmitted to the rollers 8 connected to the gearbox 7, causing the rollers 8 to rotate at both ends of the conveyor frame 4. The rollers 8 drive the conveyor belt 9 to rotate. The partitions 10 on the surface of the conveyor belt 9 separate the coffee beans, so that the coffee beans are arranged in an orderly manner on the conveyor belt and move from one end of the feed hopper 5 to the other end of the discharge hopper 11 to achieve stable conveying. The coffee beans falling from the discharge hopper 11 enter the vibrating structure. The vibrating plate 12 is installed at the top center of the support frame 13 and is powered by an external power source to generate vibration.

The support plate 14 is installed on the side of the support frame 13 to ensure the stable operation of the vibrating plate 12. The vibration of the vibrating plate 12 causes the coffee beans to gradually disperse and line up on the connecting slide 16. To avoid piling up and ensure that coffee beans enter the coffee bean sorting module 17 one by one, improving the efficiency of subsequent detection and sorting, the coffee beans enter the coffee bean sorting module 17 via the connecting slide 16. The detector 18 installed in the slot at the top of the module starts to work. It uses optical and electronic technologies to analyze the color, texture and other characteristics of the coffee beans to determine the roasting degree. If the coffee beans meet the preset roasting degree standard, the indicator light 19 on the top of the detector 18 lights up, sending a signal that the coffee beans meet the requirements, providing a basis for subsequent sorting. The detected coffee beans are sorted according to the roasting degree. When the detector 18 determines that the coffee beans are roasted to be qualified, the corresponding coffee bean outlet 20 at the bottom of the coffee bean sorting module 17 opens, and the coffee beans fall into the coffee bean collection box 21 below. The square slot at the top of the coffee bean collection box 21 corresponds to the coffee bean outlet 20, ensuring that the coffee beans fall accurately, realizing the precise sorting and classification collection of coffee beans with different roasting degrees.
