Abstract
Description
Technical Field
[0001] This disclosure relates to the field of coffee bean roasting technology, and in particular to a coffee bean cooling device and roasting equipment. Background Technology
[0002] Before grinding coffee beans, since raw coffee beans are not volatile, they need to be roasted to ensure they release their aroma. This involves raising the temperature of the beans. However, after roasting, the beans need to be cooled to prevent over-roasting due to residual heat.
[0003] Currently, there are two methods for cooling coffee beans: natural cooling and air cooling. Natural air cooling has a poor cooling effect, and coffee beans are easily affected by ambient humidity. Air cooling usually uses fans or ventilation systems to cool coffee beans, but it is necessary to ensure that each coffee bean is cooled evenly and that the air cooling efficiency is guaranteed. The existing technology CN221648819U discloses a roasting bean cooling machine that uses an air cooling solution. However, in one embodiment, the bean container only has ventilation holes at the bottom, and when the fan is working, it only blows air onto the bottom of the bean container, so that the coffee beans at the bottom of the bean container are cooled first. The coffee beans that are gradually moving away from the bottom of the bean container cannot be cooled at the same time. This makes it impossible for the coffee beans on each side to be cooled at the same time, thereby reducing the cooling efficiency of the coffee beans. This leads to over-roasting of the coffee beans due to their own residual heat, which affects the quality of the coffee beans.
[0004] Similarly, when using hot air blowing, i.e., external air intake and the fan carrying internal heat out through the air outlet, the above-mentioned cooling efficiency problem will still exist if other conditions remain unchanged. Utility Model Content
[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a coffee bean cooling device and roasting equipment that can cool all sides of a container containing coffee beans.
[0006] The purpose of this disclosure is achieved through the following technical solution:
[0007] A coffee bean cooling device includes a housing, a bean receiving assembly, a cooling fan, and a cooling chamber door assembly. The housing has a sequentially connected door opening, a cooling chamber, and an air outlet. The bean receiving assembly, the cooling fan, and the cooling chamber door assembly are all located within the cooling chamber. The bean receiving assembly includes a bean basket and a rolling rod assembly. The rolling rod assembly is connected to the housing, and the bean basket is disposed on the rolling rod assembly. The bean basket has multiple cooling holes, which are distributed on each side of the bean basket and communicate with the cooling chamber. The cooling fan is installed inside the housing, and its air outlet faces the air outlet. The cooling chamber door assembly includes a driver, a push plate, and a cooling chamber door. The driver is installed inside the housing, one end of the push plate is connected to the power output end of the driver, and the other end of the push plate is fixedly connected to the cooling chamber door, so that the driver drives the push plate and the cooling chamber door to allow airflow or isolation between the door opening and the outside air.
[0008] In one embodiment, the door opening and the air outlet are arranged on opposite sides of the outer casing.
[0009] In one embodiment, the cooling compartment door includes a door panel and a damping shaft, one end of which is fixedly connected to the push plate, and the other end of which is rotatably connected to the door panel.
[0010] In one embodiment, the side of the silo door away from the bean basket has a handle.
[0011] In one embodiment, the damping shaft includes an upper damping shaft, a middle damping shaft, and a lower damping shaft. The upper damping shaft is rotatably connected to the lower damping shaft via the middle damping shaft. The lower damping shaft is fixedly connected to the push plate, and the upper damping shaft is fixedly connected to the door panel.
[0012] In one embodiment, the rolling rod assembly includes a plurality of rolling rods spaced apart, each rolling rod including a roller and a connecting rod, the connecting rod being fixedly connected to the inner wall of the housing, the roller being sleeved on the connecting rod so that the roller rolls around the connecting rod as the center, and the bean basket being disposed on the roller.
[0013] In one embodiment, the bean receiving assembly further includes a bean receiving handle disposed on the bean receiving basket.
[0014] In one embodiment, the coffee bean cooling device further includes a baffle mounted on the housing and located within the air-cooling cavity, so as to isolate the rolling rod assembly from the driver via the baffle.
[0015] In one embodiment, the driver is a lead screw motor or a drive cylinder.
[0016] A coffee bean roasting apparatus, comprising the coffee bean cooling device described in any of the above embodiments.
[0017] Compared with the prior art, this disclosure has at least the following advantages:
[0018] After roasting, the coffee beans fall from the roasting structure into the bean receiving basket. Since the roasted coffee beans are at a high temperature, a cooling fan is needed to remove their heat. Specifically, when cooling the coffee beans, the actuator moves the push plate to move the cooling chamber door away from the outer shell, allowing the door opening to connect with the outside air. Then, the cooling fan is activated, allowing outside air to enter through the door opening and drawing in the hot air inside the air-cooling chamber. Finally, the hot air is blown out through the air outlet by the cooling fan. At the same time, there are cooling holes on each side of the bean receiving basket, allowing outside air to pass through the cooling holes under the action of the cooling fan, thus rapidly cooling the coffee beans on each side of the bean receiving basket, thereby improving cooling efficiency and preserving the aroma characteristics of the coffee beans.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0030] Please see Figures 1 to 4This is a coffee bean cooling device 10 according to an embodiment of the present invention, comprising a housing 100, a bean receiving assembly 200, a cooling fan 300, and a cooling chamber door assembly 400. The housing 100 has a chamber door opening 101, a cooling chamber 102, and an air outlet 103 connected in sequence. The bean receiving assembly 200, the cooling fan 300, and the cooling chamber door assembly 400 are all located within the cooling chamber 102. The bean receiving assembly 200 includes a bean receiving basket 210 and a rolling rod assembly 220A. The rolling rod assembly 220A is connected within the housing 100, and the bean receiving basket 210 is disposed within the housing. Specifically, a bean-receiving basket 210 can be placed on the rolling rod assembly 220A. The bean-receiving basket 210 has multiple cooling holes 211, which are distributed on each side of the basket. All cooling holes 211 communicate with the air-cooling chamber 102. A cooling fan 300 is installed inside the housing 100, with its outlet facing the outlet 103. The cooling chamber door assembly 400 includes a driver 410, a push plate 420, and a cooling chamber door 430. The driver 410 is installed inside the housing 100. Inside the chamber 100, one end of the pusher plate 420 is connected to the power output end of the driver 410, and the other end of the pusher plate 420 is fixedly connected to the cooling chamber door 430, so that the driver 410 drives the pusher plate 420 and the cooling chamber door 430 to either circulate or isolate the chamber door opening 101 from the outside air. Specifically, when coffee bean cooling is not performed, the cooling chamber door 430 is against the outer casing 100, i.e., in the closed state. After roasting, the coffee beans fall into the bean receiving basket 210. To perform the coffee bean cooling step, the driver 410 drives the pusher plate 420 to move away from the outer casing 100. The driver 410 moves in a direction that causes the cooling chamber door 430 to move away from the door opening 101, and then the coffee bean cooling process begins. At this time, the air in the door opening 101 circulates with the outside air. After the cooling process is completed, the driver 410 drives the push plate 420 to move in a direction close to the driver 410, which in turn causes the cooling chamber door 430 to move in a direction close to the door opening 101 until it touches the outer casing 100. At this time, the air in the door opening 101 is isolated from the outside air by the cooling chamber door 430.
[0031] After roasting, the coffee beans fall from the roasting structure into the bean receiving basket 210. Since the roasted coffee beans have a high temperature, the cooling fan 300 needs to remove the heat from the coffee beans. Specifically, when cooling the coffee beans, the driver 410 drives the pusher plate 420 to move so that the cooling chamber door 430 is away from the outer shell 100, so that the chamber door opening 101 is connected to the outside air. Then the cooling fan 300 is turned on, so that the outside air enters from the chamber door opening 101, and the hot air inside the air-cooling chamber 102 is drawn in by the cooling fan 300. Finally, the hot air is blown out from the air outlet 103 under the action of the cooling fan 300. At the same time, there are cooling holes 211 on each side of the bean receiving basket 210, so that the outside air passes through the cooling holes 211 under the action of the cooling fan 300, thereby allowing the coffee beans on each side of the bean receiving basket 210 to be cooled quickly, thereby improving the cooling efficiency and ensuring the aroma characteristics of the coffee beans.
[0032] Specifically, after roasting, the coffee beans fall from the roasting structure into the bean receiving basket 210. Since the roasted coffee beans are at a high temperature, air circulation with the outside is necessary to ensure that the heat is dissipated. The actuator 410 drives the pusher plate 420, indirectly driving the cooling chamber door 430 away from the outer casing 100, so that the door opening 101 connects to the outside. That is, a certain gap is maintained between the cooling chamber door 430 and the outer casing 100 near the door opening 101. Then, the cooling fan 300 is turned on, and outside air flows from the door opening 101... The air is drawn in and enters the air-cooling chamber 102. Part of the air, under the action of the cooling fan 300, passes through the cooling holes 211 to cool the roasted coffee beans. Subsequently, the heat from the coffee beans is exhausted through the air outlet 103 by the cooling fan 300. The cooling holes 211 are distributed on each side of the bean basket 210, ensuring uniform cooling of the coffee beans on that side and improving cooling efficiency. Furthermore, the airflow direction is: door opening 101 → air-cooling chamber 102 → air outlet 103. A schematic diagram of the airflow direction is shown below. Figure 4 As shown; after the coffee bean cooling process is completed, the cooling fan 300 stops working, the driver 410 drives the push plate 420 to indirectly drive the cooling chamber door 430 to abut against the outer casing 100 and seal the chamber door opening 101, so that the chamber door opening 101 is isolated from the outside air.
[0033] In one embodiment, the door opening 101 and the air outlet 103 are arranged on both sides of the outer casing 100 to ensure the flow of external air through the door opening 101, the air-cooled cavity 102 and the air outlet 103.
[0034] like Figure 1As shown, in one embodiment, the cooling chamber door 430 includes a door panel 431 and a damping shaft 432. One end of the damping shaft 432 is fixedly connected to the push plate 420, and the other end of the damping shaft 432 is rotatably connected to the door panel 431. It can be understood that the door panel 431 can be driven by the driver 410 to move horizontally, or it can rotate around the damping shaft 432 to open or close the cooling chamber door 430. Specifically, after the coffee bean cooling process is completed, the cooling chamber door 430 can be manually opened by rotating the door panel 431 around the damping shaft 432 at a certain angle to open the door. Then, the bean basket 210 can be removed from the housing 100 to retrieve the coffee beans. After removing the bean basket 210, the cooling chamber door 430 can be pushed, causing the door panel 431 to rotate in the opposite direction at a certain angle to close the door. Furthermore, a handle 4311 is provided on the side of the door panel 431 facing away from the bean basket 210. In this way, when it is necessary to open the cooling door 430, a person can grab the handle 4311 to drive the door panel 431.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the damping shaft 432 includes an upper damping shaft 4321, an intermediate shaft 4322, and a lower damping shaft 4323. The upper damping shaft 4321 is rotatably connected to the lower damping shaft 4323 via the intermediate shaft 4322. The lower damping shaft 4323 is fixedly connected to the push plate 420, and the upper damping shaft 4321 is fixedly connected to the door plate 431. When the cooling compartment door 430 is opened, since the upper damping shaft 4321 is rotatably connected to the lower damping shaft 4323 via the intermediate shaft 4322, that is, with the intermediate shaft 4322 as the rotation center, the upper damping shaft 4321 moves relative to the lower damping shaft 4323, and consequently the door plate 431 moves relative to the push plate 420, so that the door opening 101 communicates with the outside air, thus opening the door. Conversely, opening the door closes the door.
[0036] like Figures 3 to 5As shown, in one embodiment, the rolling rod assembly 220A includes a plurality of rolling rods 220 spaced apart. Each rolling rod 220 includes a roller 221 and a connecting rod 222. The connecting rod 222 is fixedly connected to the inner wall of the housing 100. The roller 221 is sleeved on the connecting rod 222 so that the roller 221 rolls around the connecting rod 222 as the center. The bean basket 210 is disposed on the roller 221. Specifically, the bean basket 210 can be placed on the roller 221. It is understandable that, on the one hand, the arrangement of multiple rolling rods 220 can be used to support the bean basket 210; on the other hand, the rollers 221 roll around the connecting rod 222, so that when the bean basket 210 is placed in or taken out, the rollers 221 of each rolling rod 220 roll, causing the bean basket 210 to move relative to each other, thus facilitating the placement or removal of the bean basket 210; furthermore, since the rolling rods 220 are spaced apart, when the cooling fan 300 is working, some air also passes through the gaps between adjacent rolling rods 220 and the cooling holes 211 at the bottom of the bean basket 210, thereby cooling the coffee beans located at the bottom of the bean basket 210, thus further playing a role in rapid heat dissipation and cooling.
[0037] like Figure 3 As shown, in one embodiment, the bean receiving assembly 200 further includes a bean receiving handle 230, which is disposed on the bean receiving basket 210. In this way, when it is necessary to remove the bean receiving basket 210, the bean receiving handle 230 can be grasped by hand to remove the bean receiving basket 210. Thus, the setting of the bean receiving handle 230 can improve the convenience of removing the bean receiving basket 210.
[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the coffee bean cooling device 10 further includes a baffle 500, which is installed on the housing 100 and located inside the air-cooling cavity 102, so that the rolling rod assembly 220A and the driver 410 are isolated by the baffle 500. In this way, when the roasted coffee beans fall into the bean receiving basket 210, some coffee beans are mixed with silver skin. After passing through the cooling hole 211, the silver skin falls onto the baffle 500, which can prevent some of the silver skin from falling onto the driver 410, so as not to affect the normal operation of the driver 410.
[0039] In one embodiment, the driver 410 is a lead screw motor or a drive cylinder. In this embodiment, the driver 410 is a lead screw motor, so that the push plate 420 moves horizontally along the lead screw track of the lead screw motor under the drive of the lead screw motor.
[0040] This disclosure also provides a coffee bean roasting apparatus, including the coffee bean cooling device 10 of any of the above embodiments.
[0041] Compared with the prior art, this disclosure has at least the following advantages:
[0042] After roasting, the coffee beans fall from the roasting structure into the bean receiving basket 210. Since the roasted coffee beans have a high temperature, the cooling fan 300 needs to remove the heat from the coffee beans. Specifically, when cooling the coffee beans, the driver 410 drives the pusher plate 420 to move so that the cooling chamber door 430 is away from the outer shell 100, so that the chamber door opening 101 is connected to the outside air. Then the cooling fan 300 is turned on, so that the outside air enters from the chamber door opening 101, and the hot air inside the air-cooling chamber 102 is drawn in by the cooling fan 300. Finally, the hot air is blown out from the air outlet 103 under the action of the cooling fan 300. At the same time, there are cooling holes 211 on each side of the bean receiving basket 210, so that the outside air passes through the cooling holes 211 under the action of the cooling fan 300, thereby allowing the coffee beans on each side of the bean receiving basket 210 to be cooled quickly, thereby improving the cooling efficiency and ensuring the aroma characteristics of the coffee beans.
[0043] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
