A coffee bean roasting heating mechanism

Abstract

This invention relates to the field of roasting technology, and in particular to a coffee bean roasting heating mechanism, comprising a support component including a tray, a heating element disposed at the end of the tray, and a cover plate disposed above the tray. The invention utilizes multiple roasting components eccentrically arranged in a circumferential array on the tray, forming multiple independent roasting spaces using storage troughs on an arc-shaped plate. Different types of coffee beans are separated and heated synchronously in their respective storage troughs, physically cutting off the direct contact path between oils and aromas, effectively avoiding flavor cross-contamination when multiple varieties are roasted in the same oven, and perfectly preserving the pure flavor of the coffee beans. Furthermore, before roasting, the arc-shaped plate can rotate around its axis, extending through the discharge channel to the outside, enabling independent and precise feeding of each compartment without interference and preventing mixing. During roasting, the storage troughs rotate back into the chamber, continuously tumbling the coffee beans inside, significantly improving the uniformity of heating and roasting efficiency.

Description

Technical Field

[0001] This invention relates to the field of baking technology, and in particular to a coffee bean roasting heating mechanism. Background Technology

[0002] In recent years, with the popularization of specialty coffee culture, more and more coffee lovers and professional tasters tend to use small or handheld coffee bean roasting equipment to conduct small-batch, frequent roasting experiments. In practical applications, in order to make blended coffee or to simultaneously compare and test green beans from different origins and with different processing methods, such as washed, sun-dried, and honey-processed beans, users often need to roast multiple different types of coffee beans at the same time.

[0003] However, most existing handheld or small coffee roasters use a single-compartment, one-piece internal structure. This structure has significant limitations: Firstly, if different types of coffee beans are mixed and heated in the same roasting chamber, a large amount of oils, moisture, and volatile aroma compounds will overflow during the high-temperature roasting stage, easily leading to cross-contamination between different bean varieties and causing severe flavor mixing, thus destroying the original unique flavor and body of each type of coffee bean. Secondly, if a batch-by-batch, single-variety roasting method is used to avoid flavor mixing, it is not only extremely time-consuming and labor-intensive, but also difficult to maintain absolutely consistent ambient temperature, hand posture, and heating time for each roasting, easily leading to a loss of objectivity in comparative evaluation. In addition, existing roasters usually require the entire lid to be removed when adding and discharging, which is extremely inconvenient when handling multiple types of coffee beans with precise feeding, and is prone to accidental spills or bean mix-ups.

[0004] Therefore, a coffee bean roasting and heating mechanism is proposed. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is: in view of the problems that existing single-compartment roasting equipment is prone to cross-contamination of flavors when processing multiple types of coffee beans at the same time, and that batch roasting is time-consuming and labor-intensive, and the process of adding multiple types of ingredients is cumbersome and easy to confuse, the present invention aims to provide a coffee bean roasting heating mechanism.

[0006] The above-mentioned technical problem is solved by the following technical solution: a coffee bean roasting heating mechanism, comprising a supporting component including a tray, a heating element disposed at the end of the tray, and a cover plate disposed above the tray; wherein a discharge channel is formed between the tray and the cover plate; a plurality of roasting components circumferentially arranged on the tray, each including a rotating shaft eccentrically disposed on the tray, an arc-shaped plate integrally formed outside the rotating shaft, and a storage trough opened on the arc-shaped plate; wherein, before roasting, the arc-shaped plate extends through the discharge channel to the outside of the supporting component, at which time different types of coffee beans are placed in each of the storage troughs, and then the rotating shaft is controlled to rotate, and each of the arc-shaped plates rotates into the supporting component, activating the heating element; to optimize roasting efficiency, the storage troughs also rotate within the supporting component during roasting.

[0007] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention, a transmission component is further included, the transmission component including a connecting frame rotatably mounted on the axial direction of the tray.

[0008] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: the connecting frame is used to support the fixed-point rotation of each of the rotating shafts, and the outer wall of each of the rotating shafts is provided with toothed grooves, while the connecting frame is provided with a first transmission gear, a second transmission gear and a third transmission gear on its axial direction.

[0009] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: the tooth groove is meshed with the first transmission gear, the first transmission gear and the second transmission gear rotate synchronously, while the third transmission gear can rotate independently.

[0010] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: the outer wall of each of the arc-shaped plates is provided with a receiving end for accommodating the grooves on the other arc-shaped plates, and the end of the storage tank is provided with a second through hole.

[0011] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention, an output component is further included, the output component including a telescopic column disposed on the connecting frame.

[0012] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: the telescopic column consists of a bottom column and a top column. The bottom column is rotatably mounted on the connecting frame via a bearing, while the top column is movably sleeved on the bottom column. An elastic element is provided between the bottom column and the top column.

[0013] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: an output gear is provided on the top column, and the output gear is meshed with the second transmission gear and the third transmission gear respectively; a control plate is provided on the cover plate at the end of the top column away from the bottom column.

[0014] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: the end face of the cover plate is respectively provided with a display screen and control buttons electrically connected to the heating element.

[0015] In a preferred embodiment of the coffee bean roasting and heating mechanism of the present invention: a first through hole is provided through the end face of the tray, and a palm pressure plate is installed under the tray by bolts.

[0016] The beneficial effects of this invention are as follows: By using multiple roasting components arranged eccentrically in a circular array on a tray, and utilizing the storage troughs on the arc-shaped plate, multiple independent roasting spaces are formed. Different types of coffee beans are separated in their respective storage troughs and heated simultaneously, physically cutting off the direct contact path between oils and aromas, effectively avoiding flavor cross-contamination when multiple varieties are roasted in the same oven, and perfectly preserving the pure flavor of the coffee beans. Furthermore, before roasting, the arc-shaped plate can rotate around its axis and extend through the discharge channel to the outside, enabling independent and precise feeding of each compartment without interference and preventing mixing. During roasting, the storage troughs rotate back into the chamber, causing the coffee beans inside to tumble continuously, significantly improving the uniformity of heating and roasting efficiency.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0026] Reference Figure 1 This embodiment provides a coffee bean roasting heating mechanism, including a support assembly 10, comprising a tray 11, a heating element 111 disposed at the end of the tray 11, and a cover plate 12 disposed above the tray 11. The support assembly 10 constitutes the main frame and heating environment of the roaster. The tray 11, as a bottom support, together with the cover plate 12 above, forms a relatively enclosed heating chamber. The heating element 111, which can be a ceramic heating plate or a ring-shaped electric heating tube, is arranged at the end of the tray 11, and can quickly generate and conduct heat within the chamber, providing the high-temperature environment required for roasting coffee beans.

[0027] A discharge channel 121 is formed between the tray 11 and the cover plate 12; the discharge channel 121 is a lateral opening connecting the internal heating chamber to the external environment. (See attached diagram.) Figure 1 and Figure 3 It is known that the cover plate 12 does not completely seal the side. This channel provides physical clearance for the subsequent unscrewing and feeding of internal components and the discharge after baking.

[0028] A number of baking components 20 arranged in a circular array on a tray 11 include a rotating shaft 21 eccentrically disposed on the tray 11, an arc-shaped plate 22 integrally formed outside the rotating shaft 21, and a storage trough 221 opened on the arc-shaped plate 22.

[0029] Combined with appendix Figures 2 to 4 Preferably, there are three roasting components 20 arranged in a 120-degree equidistant circular array. The core of each roasting component is a crescent-shaped arc plate 22. The pivot 21 is eccentrically positioned at one end of the arc plate, not at its geometric center. This eccentric design allows the arc plate 22 to produce a movement trajectory similar to unfolding and contracting as it rotates around the pivot 21. The storage trough 221 is an independent compartment for storing coffee beans.

[0030] Before roasting, the arc plate 22 extends through the discharge channel 121 to the outside of the support component 10. At this time, different types of coffee beans are placed in each storage tank 221. Then, the rotating shaft 21 is controlled to rotate, and each arc plate 22 rotates into the support component 10. The heating element 111 is activated. In order to optimize roasting efficiency, the storage tank 221 will also rotate within the support component 10 when being roasted.

[0031] This is the core interaction logic, such as Figure 4 As shown, in the feeding state, the arc-shaped plate 22 extends outward, and the three storage compartments 221 are completely exposed to the outside of the device. Users can put different coffee beans into different compartments without interference. After feeding is completed, the rotating shaft 21 rotates in the opposite direction, and the arc-shaped plate 22 retracts back into the supporting component 10 like closing petals. At this time, each storage compartment is relatively independent, achieving physical isolation of flavors. During the heating process, in order to prevent the side near the heating element 111 from burning, the storage compartment 221 continues to rotate inside the cavity, ensuring that the coffee beans in each compartment receive uniform microwave or heat radiation.

[0032] It also includes a transmission assembly 30, which includes a connecting frame 31 rotatably mounted on the axial direction of the tray 11. The transmission assembly 30 is the power transmission hub for realizing the above-mentioned unfolding or folding, as well as the baking rotation. The connecting frame 31 is similar to the planet carrier in a planetary gear mechanism. It is mounted on the central axis of the entire tray 11 and can rotate 360 ​​degrees around the central axis.

[0033] The connecting frame 31 supports the fixed-point rotation of each rotating shaft 21. Each rotating shaft 21 has toothed grooves on its outer wall, and the connecting frame 31 has a first transmission gear 32, a second transmission gear 33, and a third transmission gear 34 respectively arranged axially. (See attached diagram.) Figure 2 The shafts 21 of the three baking components are rotatably connected to the three outwardly extending cantilever arms of the connecting frame 31. The toothed grooves on the outer wall of the shaft 21 are equivalent to planetary gears, while the third transmission gear stacked in the center is equivalent to the central sun gear set. By rotating the central gear set, the movement of the outer shafts 21 can be precisely controlled.

[0034] The gear 32 meshes with the first transmission gear 33, which rotates synchronously with the second transmission gear 33. The third transmission gear 34 can rotate independently. The shaft 21 meshes only with the bottommost first transmission gear 32. Since the first transmission gear 32 and the second transmission gear 33 are coaxial and synchronous, they can be considered as a double-layer gear. Therefore, driving the second transmission gear 33 will drive the first transmission gear 32 to rotate, thereby causing the shaft 21 to rotate and enabling the arc plate 22 to unfold and retract. The third transmission gear 34 operates independently and is mainly used to drive the entire connecting frame 31 to revolve when locked.

[0035] Each arc-shaped plate 22 has a receiving end 223 on its outer wall for accommodating the grooves on other arc-shaped plates 22, and a second through hole 222 is provided at the end of the storage trough 221. Figure 3 As shown, this concave clearance notch is the receiving end 223. When the three arc-shaped plates 22 are gathered in the center, the receiving end 223 can just nest the gear part of the adjacent rotating shaft, making the entire internal structure extremely compact in the contracted state and reducing the overall volume of the equipment. The second through hole 222 is a vent hole, through which hot air and baking fumes can circulate, which not only improves heat exchange efficiency but also allows for timely dissipation of moisture.

[0036] It also includes an output component 40, which includes a telescopic column 41 mounted on a connecting frame 31. The telescopic column 41 consists of a bottom column and a top column. The bottom column is rotatably mounted on the connecting frame 31 via bearings, while the top column is movably sleeved on the bottom column. An elastic element is provided between the bottom column and the top column. An output gear 42 is provided on the top column, and the output gear 42 is meshed with the second transmission gear 33 and the third transmission gear 34 respectively. A control plate 43 is provided on the cover plate 12 at the end of the top column away from the bottom column.

[0037] The elastic element inside the telescopic column 41 gives it the ability to extend and retract vertically, which is used to change the meshing object of the output gear 42. When the control plate 43 is not pressed, only the output gear 42 is rotated. At this time, the output gear 42 only meshes with the third transmission gear 34, which drives the rotating shaft 21 to rotate through gear transmission, thereby rotating the arc plate 22 out of the bearing assembly 10 for feeding.

[0038] When the user presses the control panel 43 to overcome the spring force and lower the top column, the output gear 42 undergoes axial displacement, disengaging from the third transmission gear 34 and engaging with the second transmission gear 33. Under this pressed and rotated state, the power will directly drive the entire connecting frame 31 to rotate.

[0039] The end face of the cover plate 12 is respectively provided with a display screen T-1 and a control button T-2, which are electrically connected to the heating element 111. For example... Figure 1As shown, the cover plate 12 is equipped with a display screen T-1 and control buttons T-2, which are mainly used for displaying basic information and controlling the machine after it is powered on.

[0040] A first through hole 112 is provided through the end face of the tray 11, and a palm pressure plate 13 is bolted to the bottom of the tray 11. Figure 5 The first through hole 112 facilitates airflow circulation within the cavity; the palm pressure plate 13 installed below is ergonomic, allowing the user to comfortably support the device with their palm when used as a handheld device, and also serves to insulate against heat and prevent burns.

[0041] In summary, before baking, in the default state without pressing the control panel 43, the output gear 42 is driven to rotate. At this time, the output gear 42 only meshes with the third transmission gear 34, and through transmission, the three arc-shaped plates 22 are rotated out of the machine, as shown. Figure 4 In the lower half of the state, users can pour different types of raw beans into the three exposed storage tanks 221.

[0042] After the material storage is completed, the reverse drive output gear 42 is reversed, and the arc plate 22 retracts back into the bearing component 10, forming independent physical compartments to prevent cross-contamination of odors.

[0043] Turn on the heating element 111. At this time, press the control panel 43 to move the output gear 42 downward and switch it to mesh with the second transmission gear 33. In this pressed and rotated state, the power drives the entire connecting frame 31 to revolve, thereby causing the three internal roasting components 20 to rotate as a whole, so that the coffee beans are roasted evenly in continuous tumbling and hot air circulation.

[0044] After roasting, release the control plate 43 to reset it, re-engage it with the third transmission gear 34, and rotate the output gear again to unscrew the arc plate 22, then pour out the roasted beans.

[0045] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
