Description

Technical Field

[0001] This invention relates to the field of roasting equipment, and in particular to an energy-saving intelligent coffee bean roasting device. Background Technology

[0002] Most existing coffee bean roasters employ a hot air circulation system combined with a mechanical stirring structure. A fan drives hot airflow within the roasting chamber, while a stirring paddle continuously tumbles the coffee beans to ensure even heating. This type of equipment has a relatively mature structure and allows for some control of the roasting process by adjusting airflow, temperature, and stirring speed. It offers advantages such as ease of operation and batch roasting adaptability. However, existing coffee bean roasters still have certain drawbacks: In actual roasting, although coffee beans are tumbled as a whole by the stirring paddle, they are still prone to temporary accumulation at the bottom or in corners of the chamber, resulting in obstructed airflow and delayed temperature rise in these areas. At the same time, most current hot air circulation systems are unidirectional or uniform, and the airflow velocity decreases significantly when passing through the bean layer, especially in the middle section of the chamber axis, where airflow dead zones are easily formed, making it difficult for heat to penetrate the entire chamber. As roasting progresses, the beans release moisture and undergo chemical reactions, further exacerbating the uneven distribution of temperature and humidity in the chamber, often resulting in over-roasted beans near the heat source and under-roasted beans further away. Although operators can increase the fan power or extend the roasting time to alleviate this problem, it will bring new problems such as increased energy consumption and excessive volatilization of flavor substances, reflecting that existing roasters still have significant limitations in terms of thermal efficiency and roasting uniformity in dynamic bean clusters and complex airflow coupling scenarios. Summary of the Invention

[0003] In view of the problem in the above or existing technology that the beans are over-scorched near the heat source and under-dried at the far end, the present invention is proposed.

[0004] Therefore, the purpose of this invention is to provide an energy-saving intelligent coffee bean roasting device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An energy-saving intelligent coffee bean roasting device includes, The frame and the side panels fixedly mounted on the frame; A housing fixedly mounted on the side plate, with a main shaft rotatably mounted inside the housing; An axial radial pulse turbulence unit is disposed at the end of the main shaft, the axial radial pulse turbulence unit comprising, A turbulence assembly for simultaneously injecting pulsed airflow along the main shaft axial and radial directions; A reciprocating assembly and a control assembly for synchronously controlling the reciprocating assembly as it rotates with the spindle, the reciprocating assembly being used to generate pulsed airflow through reciprocating motion of the turbulence assembly.

[0006] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, the turbulence component includes a sealed cavity opened in the main shaft, and the surface of the main shaft is provided with a plurality of radial air jet holes communicating with the seal.

[0007] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, wherein: a flow guide is fixedly sleeved on the outside of the main shaft, and the flow guide is connected to the sealing cavity through a radial jet hole.

[0008] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, a stirring paddle is fixedly installed on the outside of the main shaft, and a plurality of axial jet holes are provided on the flow guide shroud.

[0009] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, the reciprocating component includes a sealing plate slidably installed in a sealed cavity, a sliding rod that slides through the sealed cavity is fixedly installed on the sealing plate, and a connecting plate is fixedly installed at the end of the sliding rod.

[0010] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, the control component includes a guide rod fixedly installed on the side plate, and a guide sleeve is slidably sleeved on the outer side of the guide rod.

[0011] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, a cylindrical cam is fixedly installed on the outer side of the main shaft, a cam groove is opened on the outer side of the cylindrical cam, a steel ball that is slidably connected to the cam groove is fixedly installed on the guide sleeve near the main shaft, and the connecting plate is fixedly connected to the guide sleeve.

[0012] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, a heating module for heating the heating chamber is fixedly installed on the frame.

[0013] As a preferred embodiment of the energy-saving intelligent coffee bean roasting device of the present invention, a ventilation module for circulating hot air inside the chamber is fixedly installed on the frame.

[0014] The beneficial effects of the energy-saving intelligent coffee bean roasting device of the present invention are as follows: By setting up an axial-radial pulse turbulence unit, the reciprocating components achieve synchronous axial movement during the rotation of the main shaft through the mechanical coupling of the cylindrical cam and the guide assembly, causing the volume of the sealed cavity to change periodically. This design ensures that the hot airflow is not continuously ejected, but rather alternately ejected in pulse form from the radial and axial jet holes: the radial pulse airflow directly penetrates the gaps between the beans, impacting them at the moment when the stirring paddle turns the beans into a loose state, effectively breaking up small clumps and enhancing the airflow disturbance force on the bean surface; the axial pulse airflow propels directionally along the main shaft, penetrating the entire length of the chamber, forming a two-way push and suction synergy with the suction action of the ventilation module, significantly enhancing the overall airflow fluidity inside the chamber; this multi-dimensional pulse turbulence mechanism not only enhances the heat and mass transfer efficiency between the beans and the hot air, but more importantly, it can dynamically break up the airflow stagnation zone formed by the resistance of the bean layer, promoting the uniform diffusion of heat along the axial direction of the chamber, thereby achieving efficient and balanced temperature field inside the chamber without the need for external forced convection.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-6 This embodiment provides an energy-saving intelligent coffee bean roasting device that enhances the heat and mass transfer efficiency between the coffee beans and the hot air. It includes a frame 1 and a side plate 2 fixedly mounted on the side of the frame 1; a housing 3 fixedly mounted on the side plate 2, with a horizontally mounted main shaft 4 rotatably installed inside the housing 3, and a stirring paddle 6 fixedly mounted on the outside of the main shaft 4; an axial-radial pulse turbulence unit 5 disposed at the end of the main shaft 4, the axial-radial pulse turbulence unit 5 including a turbulence component 51, which simultaneously injects pulsed airflow along the axial and radial directions of the main shaft 4 to form local turbulence, breaking up aggregated bean clumps and driving the airflow out; a reciprocating component 52 and a control component 53 for synchronously controlling the reciprocating component 52 as it rotates with the main shaft 4, the reciprocating component 52 causing the turbulence component 51 to generate pulsed airflow through reciprocating motion.

[0025] It should be noted that the chamber 3 adopts a double-layer insulation structure, with the inner layer being high-temperature resistant stainless steel and the outer layer being insulation cotton, which can reduce heat loss. Combined with the intermittent jet mode of the axial radial pulse turbulence unit 5, the energy-saving effect is further enhanced. In addition, the feed hopper 9 is located on the top of the chamber 3, and the side plate 2 has a discharge port that is connected to the chamber 3, ensuring that the coffee beans can be quickly discharged after roasting, avoiding residual over-roasting.

[0026] Reference Figures 1-6 A heating module 7 for heating the chamber 3 is fixedly installed on the frame 1, and a ventilation module 8 for circulating the hot air inside the chamber 3 is fixedly installed on the frame 1.

[0027] It should be noted that a cooling tray (such as...) is also provided on the side of the machine body. Figure 1As shown, the heating module 7 is preferably an electric heating element or a hot air heater, evenly distributed at the bottom of the chamber 3. It can monitor the temperature inside the chamber 3 in real time via a temperature sensor to achieve precise temperature control. The ventilation module 8 includes a fan and a circulating air duct. Its function is to introduce the hot air generated inside the chamber 3 by the heating module 7 into the circulating air duct, and to exhaust the gradually cooled air through the circulating air duct into the cooling tray to cool the roasted coffee beans. The start-stop rhythm of the heating module 7 and the ventilation module 8 is linked to the spindle speed 4: when the spindle speed 4 increases, the heating power and ventilation volume are increased synchronously to ensure that the pulse airflow is always hot air. The specific structures and working principles of the cooling tray, heating module 7, and ventilation module 8 are all existing technologies, therefore, they will not be described in detail in this application.

[0028] Reference Figures 1-6 The turbulence assembly 51 includes a sealing cavity 514 formed in the main shaft 4, and the main shaft 4 has a plurality of radial jet holes 511 connected to the seal on its surface.

[0029] It should be noted that the volume design of the sealing cavity 514 is adapted to the stroke of the reciprocating component 52. When the sealing plate 522 reciprocates, the air pressure inside the cavity changes periodically, which just meets the injection pressure requirements of the radial jet hole 511. If the pressure is too low, the airflow penetration will be insufficient and it will not be able to break up the coffee beans; if the pressure is too high, it will easily cause mechanical damage to the coffee beans. The radial jet holes 511 are evenly distributed in the four circumferential directions along the main shaft and are axially spaced. The hole diameter is smaller than the diameter of the coffee beans. The openings of the radial jet holes 511 and the axial jet holes 513 are chamfered. This can not only avoid the waste of airflow caused by vortices during airflow injection, but also prevent coffee bean fragments or impurities from entering the sealing cavity 514, and avoid affecting the jetting due to blockage of the radial jet holes 511 and the axial jet holes 513.

[0030] Reference Figures 1-6 The main shaft 4 is fixedly fitted with a flow guide 512. The flow guide 512 is connected to the sealing cavity 514 through a radial jet hole 511. The flow guide 512 has several axial jet holes 513 on the side near the agitator 6.

[0031] It should be noted that the flow guide shroud 512 has a ring-shaped structure and is coaxially sleeved on the outside of the main shaft 4. The airflow ejected from several axial jet holes 513 first enters the flow guide shroud 512, and then is guided by the inner wall of the flow guide shroud 512 before being blown axially to the coffee bean cluster, avoiding excessive local disturbance caused by the airflow from a single jet hole being too concentrated. The axial jet holes 513 are located on the end face of the flow guide shroud 512 near the stirring paddle 6, and are evenly distributed around the circumference of the flow guide shroud 512. Their jet direction is parallel to the axis of the main shaft 4 and faces the exhaust direction of the ventilation module 8. The core function of the hole 513 is to fill the axial airflow blind zone of the chamber 3. When the main shaft 4 rotates, the axial jet hole 513 sprays pulsed airflow into the chamber 3, pushing the hot airflow from one end of the chamber to the other. This not only solves the problem of excessive axial temperature difference in the chamber 3 in the prior art, making the temperature difference in each area of ​​the chamber 3 more balanced, but also blows the hot air towards the ventilation module 8, thereby assisting the ventilation module 8 in exhausting air. In addition, the outer surface of the guide shroud 512 is designed with an arc shape, which can reduce the frictional resistance with coffee beans and prevent the coffee beans from being scratched.

[0032] Reference Figures 1-6 The reciprocating assembly 52 includes a sealing plate 522 slidably installed in the sealing cavity 514. A sliding rod 521 that slides through the sealing cavity 514 is fixedly installed on the side of the sealing plate 522 away from the stirring paddle 6. A connecting plate 523 is fixedly installed at the end of the sliding rod 521.

[0033] It should be noted that the edge of the sealing plate 522 is embedded with a high-temperature resistant sealing ring, which forms an interference fit with the inner wall of the sealing cavity 514 to ensure that there is no airflow leakage when the sealing plate 522 reciprocates, and to ensure that the high-pressure airflow generated by each compression can be completely ejected through the radial jet hole 511 and the axial jet hole 513; the slide rod 521 is made of high-strength stainless steel, and a guide sealing sleeve is provided at the penetration point between it and the sealing cavity 514, which not only restricts the slide rod 521 to slide only along the axial direction, but also further enhances the sealing effect and prevents airflow leakage from the penetration point; the connecting plate 523 has an L-shaped structure, one end of which is welded and fixed to the slide rod 521, and the other end is detachably connected to the guide sleeve 532 by bolts, which is convenient for later maintenance and replacement.

[0034] In practical use, the operator first sets the target roasting temperature, and the heating module 7 starts to preheat the inner cavity of the chamber 3. At the same time, the ventilation module 8 starts to form a hot air circulation in the chamber 3 through the circulating air duct. At this time, the ventilation module 8 continuously delivers the heated airflow to the air inlet of the sealed cavity 514 to reserve a stable source of hot airflow for subsequent pulse jets, and at the same time provides a uniform initial temperature environment for coffee bean roasting.

[0035] Once the temperature inside chamber 3 reaches the preset preheating temperature, the operator adds coffee beans to be roasted into chamber 3 through the feed hopper 9 at the top of chamber 3. After the coffee beans enter chamber 3, the main shaft 4 starts to rotate, simultaneously driving the stirring paddle 6 to rotate. The stirring paddle 6 moves in a circular motion with the main shaft 4, turning the coffee beans inside chamber 3 from the bottom up, and then scattering them by gravity, forming a continuous dynamic dispersion state, avoiding uneven heating of coffee beans due to gravity accumulation at the bottom of the chamber. At this stage, the control component 53 starts synchronously with the rotation of the main shaft 4, starting to drive the reciprocating component 52 to perform preliminary reciprocating motion, preparing for subsequent pulse jet spraying.

[0036] As the main shaft 4 continues to rotate, the stirring paddle 6 continuously breaks up and tumbles the coffee beans. The control component 53 drives the reciprocating component 52 into a stable reciprocating cycle, realizing the pulse action of air intake and exhaust. Specifically, the control component 53 drives the slide bar 521 to move away from the sealing cavity 514 through the connecting plate 523, thereby pulling the sealing plate 522 back synchronously in the sealing cavity 514, so that the internal volume of the sealing cavity 514 expands and a negative pressure is formed. At this time, the hot airflow delivered by the ventilation module 8 is drawn into the sealing cavity 514 through the air inlet to complete the airflow reserve. The whole process is synchronized with the timing of the stirring paddle 6 turning the coffee beans upward and the expansion of the gaps between the coffee beans in the box 3.

[0037] As the stirring paddle 6 continuously agitates the coffee beans until they are dispersed, the control component 53 drives the slide bar 521 towards the sealed cavity 514. The sealing plate 522 slides forward within the sealed cavity 514, compressing the hot airflow inside and causing the air pressure inside the cavity to rise rapidly. The high-pressure hot airflow is ejected through the radial jet holes 511 on the surface of the main shaft 4, directly impacting the dispersed coffee bean clusters, forming local turbulence, and breaking up any remaining small bean clumps. At the same time, some of the hot airflow enters the guide shroud 512 through the radial jet holes 511. After being guided by the inner wall of the guide shroud 512, it is ejected from the axial jet holes 513 along the axis of the main shaft 4, filling the axial airflow blind zone inside the housing 3. This pushes the hot airflow from the end of the housing 3 away from the feed hopper 9 to the end near the feed hopper 9, making the temperature difference between different areas inside the housing 3 tend to be more even. Meanwhile, the presence of coffee beans inside the housing 3 creates local airflow resistance, resulting in an airflow stagnation zone near the middle of the housing 3 and away from the air duct inlet. The pulsed airflow ejected from the axial jet port 513 has a clear directional thrust. The airflow flows along the axis of the main shaft 4 towards the ventilation module 8, forming an active pushing force. This works in synergy with the suction of the ventilation module 8, directly breaking the stagnant airflow in the stagnant zone. This significantly increases the overall airflow velocity within the chamber 3, allowing the hot airflow to penetrate the chamber more quickly and complete the closed-loop cycle of heating, heat exchange, and exhaust. This synergistic effect avoids the ventilation module 8 relying solely on its own power to overcome airflow resistance, significantly reducing the load pressure on the fan. Furthermore, the hot airflow within the chamber 3 gradually cools down during natural circulation due to heat exchange with the inner wall of the chamber 3 and the heat absorption of the coffee beans. This results in the airflow temperature near the air inlet side of the ventilation module 8 being lower than the average temperature within the chamber 3, affecting roasting uniformity. The auxiliary circulation function of the axial airflow shortens the residence time of the hot airflow within the chamber 3, reducing its contact time with the low-temperature chamber wall and increasing the temperature of the airflow entering the circulation duct.

[0038] As the roasting process progresses, the internal moisture of the coffee beans gradually evaporates, and the Maillard reaction and caramelization reactions begin, requiring greater stability in temperature and airflow. At this point, if the operator increases the spindle speed 4 and the frequency of coffee bean turning according to roasting needs, the heating power of the heating module 7 and the ventilation volume of the ventilation module 8 will be increased synchronously to ensure that the pulse jet airflow is always a stable hot airflow, avoiding temperature fluctuations inside the chamber 3 caused by the injection of cold airflow, and ensuring that the reaction proceeds smoothly. The pulse airflow continuously washes the surface of the coffee beans, enhancing heat transfer and ensuring that each coffee bean is roasted to a uniform degree.

[0039] When the coffee beans reach the preset roasting level (achieved through time control or flavor monitoring), the main shaft 4 continues to rotate, and the stirring paddle 6 continues to tumble the coffee beans to prevent the remaining coffee beans in the chamber 3 from being over-roasted. The operator opens the discharge port on the side plate 2, which is connected to the chamber 3, and continuously pushes the roasted coffee beans to the discharge port, allowing them to quickly fall into the cooling tray on the side of the machine. At this time, the ventilation module 8 introduces part of the cooled airflow from the circulating air duct into the cooling tray to quickly cool the freshly roasted coffee beans, terminate the roasting reaction, and lock in the final flavor of the coffee beans.

[0040] Reference Figures 1-6 The control component 53 includes a guide rod 531 fixedly installed on the side plate 2 away from the housing 3, and a guide sleeve 532 slidably sleeved on the outer side of the guide rod 531; a cylindrical cam 534 fixedly installed on the outer side of the main shaft 4, and a cam groove 535 is opened on the outer side of the cylindrical cam 534; a steel ball 533 slidably connected to the cam groove 535 is fixedly installed on the side of the guide sleeve 532 near the main shaft 4; and the connecting plate 523 is fixedly connected to the guide sleeve 532.

[0041] It should be noted that the cylindrical cam 534 is keyed to the main shaft 4 and rotates synchronously with the main shaft 4. The cam groove 535 on its outer side has a sinusoidal curve profile. The sinusoidal curve profile design allows the steel ball 533 to drive the guide sleeve 532 to make a smooth reciprocating linear motion along the guide rod 531 when sliding in the groove, avoiding movement jamming. The steel ball 533 is installed at the end of the guide sleeve 532 through ball bearings, which can reduce the coefficient of friction with the cam groove 535 and improve service life. The guide rod 531 is a rounded square shaft, ensuring that the guide sleeve 532 can only slide along the axial direction of the guide rod 531, without radial movement. The offset ensures that the movement trajectory of the sealing plate 522 is coaxial with that of the sealing cavity 514, thus avoiding sealing failure caused by friction between the sealing plate 522 and the cavity wall of the sealing cavity 514. The control component 53 can control the reciprocating motion of the reciprocating component 52 without additional power synchronization. For each rotation of the main shaft 4, the cam groove 535 drives the guide sleeve 532 to complete one reciprocating motion, that is, one intake and exhaust cycle. The timing of the exhaust is exactly matched with the moment when the stirring paddle 6 turns the coffee beans into a dispersed state. At this time, the gap between the coffee beans is the largest, the airflow penetration is the strongest, and the heat transfer efficiency is the best, realizing the adaptive coordination of motion and exhaust.

[0042] In practical use, when the main shaft 4 starts to rotate, the cylindrical cam 534 rotates synchronously with the main shaft 4. At this time, the stirring paddle 6 inside the housing 3 tumbles the coffee beans synchronously with the main shaft 4. When the cylindrical cam 534 rotates, the sinusoidal profile of the cam groove 535 rotates synchronously, and the groove wall forms continuous contact and relative sliding with the steel ball 533 on the guide sleeve 532. When the protruding part of the cam groove 535 contacts the steel ball 533, it will generate a thrust along the axial direction of the main shaft 4 on the steel ball 533, pushing the guide sleeve 532 to slide along the guide rod 531 towards the main shaft 4. When the recessed part of the cam groove 535 rotates to the position of the steel ball 533, the thrust disappears. Guided by the contour of the subsequent cam groove 535, the guide sleeve 532 slides along the guide rod 531 in a direction away from the main shaft 4, completing one reciprocating stroke. The continuous smoothness of the sine curve avoids abrupt changes in motion. The steel ball 533 is installed at the end of the guide sleeve 532 through a ball bearing, which converts sliding friction into rolling friction. The coefficient of friction is greatly reduced, which not only ensures the smoothness of motion but also reduces component wear, making it suitable for long-term working scenarios where the main shaft 4 rotates continuously during baking.

[0043] The reciprocating linear motion of the guide sleeve 532 is transmitted to the slide rod 521 through the connecting plate 523, which in turn drives the sealing plate 522 to slide axially along the sealing cavity 514. For each rotation of the main shaft 4, the sinusoidal curve profile of the cam groove 535 drives the steel ball 533 to complete one push-back cycle, and the guide sleeve 532 completes one complete reciprocating motion. Then, through the connecting plate 523 and the slide rod 521, the sealing plate 522 completes one intake and exhaust cycle.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
