Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean roasting, in particular to a coffee bean roasting device with a flip structure. Background Art

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Raw coffee beans themselves do not have any coffee aroma. Only after they are roasted can you smell the rich coffee aroma. During the roasting process, the coffee beans will undergo a series of chemical changes. The green coffee beans will lose some moisture, turn yellow, and expand into a low-density fluffy state. The volume will increase by about one-fold, and they will begin to show a light brown color after light roasting. As the roasting deepens, the color of the coffee beans will gradually darken, and eventually form components that can release the coffee aroma.

[0003] Coffee bean roasting is the process of transforming the internal components of coffee beans and is also one of the key factors that determine the final flavor of coffee beans. Existing roasting is done by hand in a pot, which is labor-intensive and the uneven heating during the roasting process leads to high roasting quality.

[0004] In the prior art, a Chinese patent application with publication number CN212787370U has been proposed to address the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: a coffee bean roasting device comprising a housing and a housing cover, wherein a feed tray and a partition are disposed within the housing, the feed tray being located above the partition with a gap between the feed tray and the partition, a fan being disposed at the bottom of the housing, a heating coil being disposed on the partition, and a low-speed motor being disposed at the top of the housing, the output end of the low-speed motor being connected to a rotating shaft through the housing cover, a turning blade being movably connected to the rotating shaft, the turning blade being located in the feed tray, and the housing cover being snap-connected to the housing. The present utility model aims to provide a coffee bean roasting device that improves roasting quality and efficiency with reduced labor intensity. However, in the above-mentioned solution, there is a certain distance between the turning blade and the feed tray. When the coffee beans are turned by the turning blade, if there are fragments or impurities in the coffee beans, the coffee beans can easily become stuck in the gap between the turning blade and the feed tray, thereby damaging the turning blade and, in turn, crushing other coffee beans, affecting the roasting effect of the coffee beans. Utility Model Content

[0005] The purpose of the present invention is to provide a coffee bean roasting device with a flip structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A coffee bean roasting device with a flip structure comprises a roasting box; a top cover is clamped on the top of the roasting box, a fixed plate is fixedly installed inside the roasting box, a partition is fixedly connected to the inside of the fixed plate, a surface of the partition is provided with a plurality of through holes smaller than the volume of the coffee beans, a drying component is provided inside the roasting box at the bottom of the fixed plate, a flip plate is provided inside the roasting box on the top of the partition, a motor is fixedly installed on the top of the top cover, the output shaft of the motor extends to the inside of the top cover and is fixedly connected to the top surface of the flip plate, a filter box is fixedly installed on the top of the top cover on one side of the motor, a controller is fixedly connected to one end surface of the filter box, a baffle is fixedly installed inside the filter box, a filter plate inclined toward the bottom of the other side is fixedly installed inside the filter box, the other side surface of the filter plate is fixedly connected to the surface of the baffle, and a discharge port is provided on one side surface of the filter box at the bottom of the filter plate.

[0008] In the prior art, there is a certain distance between the turning blade and the material tray. When the turning blade is used to turn the coffee beans, if there are fragments or impurities in the coffee beans, the coffee beans are easily stuck in the gap between the turning blade and the material tray, which may cause damage to the turning blade, and further may cause other coffee beans to be crushed, affecting the roasting effect of the coffee beans. By installing a filter box, the coffee beans to be roasted can be pre-processed, wherein the coffee beans to be roasted are poured into the interior of the filter box, and the coffee beans can be filtered by installing a filter plate. Impurities or broken coffee bean particles with a volume less than or equal to the through-holes opened on the surface of the filter plate can slide to the bottom through the through-holes of the filter plate. Coffee beans with a volume greater than the through-holes opened on the surface of the filter plate can slide to the other side along the top surface of the filter plate and then enter the interior of the roasting box, thereby achieving filtering pre-processing of the coffee beans, preventing impurities or broken coffee bean particles from directly entering the interior of the roasting box and getting stuck in the gap between the first silicone sleeve and the partition and the baffle plate, thereby avoiding affecting the turning effect of the first silicone sleeve on the coffee beans, thereby improving the roasting effect of the subsequent drying assembly on the coffee beans.

[0009] A further improvement of the technical solution of the present invention is that a material blocking plate is fixedly mounted on the top surface of the fixed plate, and the top surface of the material blocking plate is an inclined surface inclined toward the bottom inside.

[0010] The above-mentioned technical solution is adopted. In this solution, when the motor drives the flip plate to rotate, the flip plate easily pushes some coffee beans away from the top surface of the partition, so that they stay on the top surface of the fixed plate, resulting in the coffee beans at this position cannot be properly roasted, resulting in uneven heating of the coffee beans, affecting the roasting effect of the coffee beans. In this application, a baffle plate is installed, and the top surface of the baffle plate is set to an inclined surface inclined toward the bottom inside. When the flip plate flips the coffee beans, if some coffee beans roll outward, they will roll back to the top surface of the partition along the inclined surface of the baffle plate, thereby preventing the coffee beans from being too far away from the top surface of the partition and unable to be roasted normally, thereby improving the roasting effect of the coffee beans.

[0011] A further improvement of the technical solution of the present utility model is that a limit plate is fixedly installed inside the filter box on the top of the filter plate.

[0012] The above technical solution is adopted. In this solution, if the operator pours a large amount of coffee beans directly into the interior of the filter box at one time, the coffee beans at a higher position will not contact the surface of the filter plate and will roll to the other side, thereby affecting the filtering effect of the filter plate on the coffee beans. In this application, by installing a limit plate, the movement trajectory of the coffee beans can be guided and limited, which ensures to a certain extent that the coffee beans can normally contact the filter plate, thereby facilitating the use of the filter plate to filter the coffee beans. After the filtration is completed, the qualified coffee beans slide to the other side from the gap between the bottom of the limit plate and the top of the filter plate, thereby improving the filtering effect of the filter plate on the coffee beans.

[0013] A further improvement of the technical solution of the present utility model is that a second silicone sleeve is attached to the outer surface of the limiting plate.

[0014] The above-mentioned technical solution is adopted. In this solution, the hardness of the limiting plate itself is relatively high. When the coffee beans contact the baffle on the surface of the limiting plate, the coffee beans are easily damaged by collision, which easily causes waste of coffee beans. In this application, a second silicone sleeve is provided on the outer surface of the limiting plate. The silicone itself is a soft material, thereby reducing the possibility of the coffee beans being damaged by collision and improving the effect of loading the coffee beans.

[0015] A further improvement of the technical solution of the present utility model is that a material guide plate is fixedly installed on one side surface of the baffle at the bottom of the filter plate, one side surface of the material guide plate is fixedly connected to the inner wall of the filter box at the bottom of the discharge port, and the material guide plate is inclined toward the bottom of one side.

[0016] The above-mentioned technical solution is adopted. In this solution, after the impurities and broken coffee bean particles pass through the surface of the filter plate, most of the impurities will still remain inside the filter box, making it inconvenient for the operator to take them out and clean them, thereby increasing the operator's workload. In this application, by installing a guide plate and tilting the guide plate, it is possible to guide the impurities and broken coffee bean particles to one side, so that they are automatically discharged from the interior of the filter box from the discharge port, thereby reducing the operator's workload and making it easier for the operator to clean them.

[0017] A further improvement of the technical solution of the present utility model is that a first silicone sleeve is attached to the outer surface of the flip plate.

[0018] The above technical solution is adopted. In this solution, a first silicone sleeve is provided on the outer surface of the flip plate. Since silicone itself is a soft material, the possibility of coffee beans being damaged by the flip plate is reduced, thereby improving the effect of flipping the coffee beans.

[0019] A further improvement of the technical solution of the present invention is that a guide plate is fixedly installed inside the baking box outside the drying assembly, and the top surface of the guide plate is fixedly connected to the bottom surface of the fixed plate.

[0020] The above technical solution is adopted. In this solution, by installing a guide plate, the hot air flow generated by the drying component can be reduced and guided, ensuring that the hot air can pass through the partition and blow to the surface of the coffee beans, roasting the coffee beans, thereby improving the roasting effect.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0022] 1. The utility model provides a coffee bean roasting device with a flipping structure, which can pre-process the coffee beans by installing a filter box, wherein after the coffee beans to be roasted are poured into the interior of the filter box, the coffee beans can be filtered by using a filter plate, so that impurities or broken coffee bean particles with a volume smaller than or equal to the through holes opened on the surface of the filter plate slide through the through holes of the filter plate to the bottom, and coffee beans with a volume larger than the through holes opened on the surface of the filter plate slide along the surface of the filter plate into the interior of the roasting box, thereby preventing impurities or broken coffee bean particles from entering the interior of the roasting box and getting stuck in the gaps between the first silicone sleeve and the partition plate and the baffle plate, thereby avoiding affecting the flipping effect of the first silicone sleeve on the coffee beans, and improving the effect of the subsequent drying component on roasting the coffee beans.

[0023] 2. The utility model provides a coffee bean roasting device with a flipping structure. By installing a baffle plate and setting its surface into an inclined surface, the coffee beans will not roll away from the top surface of the partition during the flipping plate flipping the coffee beans, thereby preventing the coffee beans from being too far away from the top surface of the partition and unable to be roasted normally, thereby improving the effect of coffee bean roasting.

[0024] 3. The utility model provides a coffee bean roasting device with a flipping structure. By installing a limit plate, it can ensure that the coffee beans are in normal contact with the filter plate to a certain extent, thereby facilitating the use of the filter plate to filter the coffee beans, thereby improving the filtering effect of the filter plate on the coffee beans. In addition, by arranging the first silicone sleeve and the second silicone sleeve, because the silicone itself is a soft material, it can reduce the possibility of the coffee beans being damaged due to collision with the flipping plate and the limit plate, thereby improving the effect of loading and flipping the coffee beans, and further improving the effect of subsequent coffee bean roasting.

[0032] The present invention is further described in detail below with reference to the embodiments:

[0033] Example 1

[0034] like Figure 1 、 Figure 3 and Figure 4As shown, the utility model provides a coffee bean roasting device with a flip structure, including a roasting box 1; a top cover 2 is clamped on the top of the roasting box 1, a fixed plate 13 is fixedly installed inside the roasting box 1, and a partition 14 is fixedly connected to the inside of the fixed plate 13, and a surface of the partition 14 is provided with a plurality of through holes smaller than the volume of the coffee beans, a drying assembly 15 is provided inside the roasting box 1 at the bottom of the fixed plate 13, and a flip plate 8 is provided inside the roasting box 1 at the top of the partition 14, a motor 5 is fixedly installed on the top of the top cover 2, the output shaft of the motor 5 extends to the inside of the top cover 2 and is fixedly connected to the top surface of the flip plate 8, a filter box 3 is fixedly installed on the top of the top cover 2 on one side of the motor 5, and a controller 4 is fixedly connected to one end surface of the filter box 3, a baffle 10 is fixedly installed inside the filter box 3, and a filter plate 18 is fixedly installed inside the filter box 3, which is inclined toward the bottom of the other side, and the other side surface of the filter plate 18 is fixedly connected to the surface of the baffle 10, and a discharge port 7 is provided on one side surface of the filter box 3 at the bottom of the filter plate 18.

[0035] In this embodiment, there is a certain distance between the turning blade and the material tray set in the prior art. In the process of turning the coffee beans by the turning blade, if there are fragments or impurities in the coffee beans, the coffee beans are easily stuck in the gap between the turning blade and the material tray, which may cause damage to the turning blade, and then may cause other coffee beans to be crushed, affecting the roasting effect of the coffee beans. By installing the filter box 3, the coffee beans to be roasted can be pre-processed, wherein the coffee beans to be roasted are poured into the interior of the filter box 3, and the coffee beans can be filtered by installing the filter plate 18, and the volume is less than or equal to the filter plate Impurities or broken coffee bean particles in the through holes opened on the surface of 18 can pass through the through holes of the filter plate 18 and slide to the bottom. Coffee beans with a volume larger than the through holes opened on the surface of the filter plate 18 can slide to the other side along the top surface of the filter plate 18 and then enter the interior of the roasting box 1, thereby achieving filtering pretreatment of the coffee beans and preventing impurities or broken coffee bean particles from directly entering the interior of the roasting box 1 and getting stuck in the gap between the first silicone sleeve 9 and the partition 14 and the baffle plate 17, thereby avoiding affecting the turning effect of the first silicone sleeve 9 on the coffee beans, thereby improving the effect of the subsequent drying component 15 on the coffee bean roasting.

[0036] Example 2

[0037] like Figure 1 、 Figure 4 and Figure 5 As shown, based on Example 1, the present invention provides a technical solution: preferably, a baffle plate 17 is fixedly installed on the top surface of the fixing plate 13, and the top surface of the baffle plate 17 is an inclined surface inclined toward the bottom inside.

[0038] In this embodiment, when the motor 5 drives the flip plate 8 to rotate, the flip plate 8 easily pushes some coffee beans away from the top surface of the partition 14, so that they stay on the top surface of the fixed plate 13, resulting in the coffee beans at this position cannot be properly roasted, resulting in uneven heating of the coffee beans, affecting the roasting effect of the coffee beans. In this application, a baffle plate 17 is installed, and the top surface of the baffle plate 17 is set to an inclined surface inclined toward the bottom inside. When the flip plate 8 flips the coffee beans, if some coffee beans roll outward, they will roll back to the top surface of the partition 14 along the inclined surface of the baffle plate 17, thereby preventing the coffee beans from being too far away from the top surface of the partition 14 and unable to be roasted normally, thereby improving the roasting effect of the coffee beans.

[0039] Example 3

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, based on Example 2, the utility model provides a technical solution: preferably, a limit plate 11 is fixedly installed inside the filter box 3 at the top of the filter plate 18, and a second silicone sleeve 12 is attached to the outer surface of the limit plate 11. A guide plate 6 is fixedly installed on one side surface of the baffle 10 at the bottom of the filter plate 18, and one side surface of the guide plate 6 is fixedly connected to the inner wall of the filter box 3 at the bottom of the discharge port 7, and the guide plate 6 is inclined toward the bottom of one side.

[0041] In this embodiment, if the operator pours a large amount of coffee beans directly into the filter box 3 at one time, the coffee beans at a higher position will not contact the surface of the filter plate 18 and will roll to the other side, thereby affecting the filtering effect of the filter plate 18 on the coffee beans. In this application, by installing the limiting plate 11, the movement trajectory of the coffee beans can be guided and limited, which ensures that the coffee beans can normally contact the filter plate 18 to a certain extent, thereby facilitating the use of the filter plate 18 to filter the coffee beans. After the filtration is completed, the qualified coffee beans slide to the other side from the gap between the bottom of the limiting plate 11 and the top of the filter plate 18, thereby improving the filtering effect of the filter plate 18 on the coffee beans; the limiting plate 11 itself has a high hardness, and when the coffee beans contact the baffle 10 on the surface of the limiting plate 11, the coffee beans are easily impacted and broken. The coffee beans are easily damaged and thus wasteful. In the present application, a second silicone sleeve 12 is provided on the outer surface of the limiting plate 11. The silicone itself is made of a soft material, which can reduce the possibility of the coffee beans being damaged by collision and improve the effect of feeding the coffee beans. After the impurities and broken coffee bean particles pass through the surface of the filter plate 18, most of the impurities will still remain inside the filter box 3, making it inconvenient for the operator to take them out and clean them, thereby increasing the workload of the operator. In the present application, a guide plate 6 is installed and tilted to guide the impurities and broken coffee bean particles to one side, so that they are automatically discharged from the interior of the filter box 3 from the discharge port 7, thereby reducing the workload of the operator and making it easier for the operator to clean them.

[0042] Example 4

[0043] like Figure 1 、 Figure 4 and Figure 5 As shown, based on Example 3, the present invention provides a technical solution: preferably, a first silicone sleeve 9 is attached to the outer surface of the flip plate 8, and a guide plate 16 is fixedly installed inside the baking box 1 outside the drying component 15, and the top surface of the guide plate 16 is fixedly connected to the bottom surface of the fixed plate 13.

[0044] In this embodiment, by providing a first silicone sleeve 9 on the outer surface of the flip plate 8, since silicone itself is a soft material, the possibility of the coffee beans being damaged by the flip plate 8 can be reduced, thereby improving the effect of flipping the coffee beans; by installing the guide plate 16, the flow direction of the hot air generated by the drying component 15 can be reduced and guided, ensuring that the hot air can pass through the partition 14 and blow to the surface of the coffee beans, thereby roasting the coffee beans, thereby improving the roasting effect.

[0045] The working principle of the coffee bean roasting device with a flip structure is described in detail below.

[0046] like Figure 1-Figure 5As shown, the operator pours the coffee beans to be roasted into the interior of the filter box 3. The coffee beans are guided by the limit plate 11 to contact the surface of the filter plate 18, and then the filter plate 18 is used to filter the coffee beans, so that impurities or broken coffee bean particles with a volume less than or equal to the through holes opened on the surface of the filter plate 18 pass through the through holes of the filter plate 18 and slide to one side along the guide plate 6, and are finally discharged from the discharge port 7. The coffee beans with a volume larger than the through holes opened on the surface of the filter plate 18 slide to the other side along the top surface of the filter plate 18 into the interior of the roasting box 1. The operator can use the motor 5 to drive the turning plate 8 to rotate to turn the coffee beans. At the same time, the baffle plate 17 ensures that the coffee beans slide inward to the top surface of the partition 14, and uses the drying component 15 to blow hot air through the surface of the partition 14 to the coffee beans, thereby realizing the roasting of the coffee beans. After the roasting is completed, the operator can remove the top cover 2 from the top to separate the top cover 2 from the roasting box 1, thereby facilitating the removal of the roasted coffee beans.

[0047] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
