Description

Roasting detection system and method

Technical Field

The present invention relates to roasting and detecting systems and methods, and more particularly, to a coffee roasting and detecting system and method.

Background

In recent years, coffee has become increasingly popular. The phenomenon that each cafe appears in a street and a small lane like a spring bamboo shoot after raining in recent years is enough to show that the quality is an indispensable factor at the same time when the demand of people for coffee is increased. In other words, the preferences of people have been raised from canned coffee available in general convenience stores to high quality freshly brewed coffee that is expected to be carefully brewed manually from a cafe in one cup. However, it is the coffee beans themselves and the way they are roasted that are the most important to brew a good cup of coffee.

In the process of baking coffee beans, the prior art equipment can only record the firepower, wind speed, wind temperature, boiler rotation speed, temperature difference and humidity as the basis for determining the baking time. In a general roasting process, a small amount of coffee beans are taken out using a probe, and the color thereof is visually observed, or whether the roasting is completed is empirically judged according to the popping sound or smell thereof during the roasting. However, this method of determining roasting of coffee beans using the rule of thumb is too subjective to be detected and evaluated in a scientific and quantitative manner. Moreover, this conventional approach requires an experienced coffee bean baker to operate, which is cost prohibitive and undesirable to the public.

Therefore, it is desirable to provide a baking and inspection system and method for fully automatically baking and inspecting an agricultural crop.

The invention provides a baking and detecting system which can be used for baking and detecting an agricultural crop in a fully automatic mode. For example, the agricultural crop may be coffee beans. In the present invention, the operator can set the roasting degree and aroma flavor of the coffee beans in advance to roast the coffee beans customized to the customer. The degree of baking is, for example, deep baking, medium baking, or low baking. The difference in baking degree can be distinguished by setting. In other embodiments of the present invention, the roasting and inspection system may be applied to other objects, such as other crops that need to be roasted or baked.

Referring to fig. 1 and 2, fig. 1 is a perspective view of a baking and detecting system 100 according to a first embodiment of the present invention, and fig. 2 is a side view of the baking and detecting system 100 according to fig. 1. The baking and detecting system 100 of the present embodiment includes a baking device 1, a detecting device 2 and a control device 3. The detecting device 2 is arranged beside the baking device 1. The control device 3 is electrically connected to the baking device 1 and the detecting device 2, respectively, to control the operations of the baking device 1 and the detecting device 2.

In the structure of the baking apparatus 1 of the present embodiment, the baking apparatus 1 includes a hollow inner cylinder 4 and a hollow outer cylinder 5, and the outer cylinder 5 is disposed outside at least a portion of the inner cylinder 4. In more detail, the outer cylinder 5 disclosed in the present embodiment surrounds a portion of the inner cylinder 4. In addition, the baking device 1 further comprises a first driving device 6 and a second driving device 7. The first driving device 6 and the second driving device 7 may be respectively located at two opposite sides of the inner cylinder 4. The first driving device 6 is coupled to the inner cylinder 4 to provide a first external force to the inner cylinder 4, so that the inner cylinder 4 can rotate along an axis a under the first external force. The second driving device 7 is coupled to the outer cylinder 5 to provide a second external force to the outer cylinder 5, so that the outer cylinder 5 is moved relative to the inner cylinder 4 by the second external force, and the outer cylinder 5 can be located at least in a first position and a second position. The outer tube 5 of the present embodiment is rotated around the inner tube 4 by the second external force along the same axis a as the rotation of the inner tube 4. In this embodiment, the outer cylinder 5 rotates in the same direction around the inner cylinder 4. However, in other embodiments, the outer barrel 5 may rotate about the inner barrel 4 in a reverse manner. In addition, a sliding rail and/or bearing structure (not shown) may be included between the inner cylinder 4 and the outer cylinder 5 to allow the inner cylinder 4 and the outer cylinder 5 to smoothly rotate relative to each other.

The inner cylinder 4 of the present embodiment is cylindrical, and the inner cylinder 4 includes a first annular wall 40 and two bottom covers 42. The bottom covers 42 are respectively disposed at two opposite ends of the first annular wall 40 to close the two ends of the first annular wall 40. One of the bottom covers 42 may include a door (not shown) that is pivotable to remove the object 400 (e.g., roasted coffee beans) from the inner cartridge 4, and the other bottom cover 42 is mechanically coupled to the power source of the first drive means 6.

In this embodiment, the outer cylinder 5 is also cylindrical and comprises a second annular wall 50, a guiding post 8 and an outer cover 9. The second annular wall 50 surrounds the first annular wall 40 of the inner barrel 4. The guide post 8 is disposed on the second annular wall 50 and extends radially outwardly from the second annular wall 50. The guide post 8 is hollow to form a channel. The cover 9 is movably pivoted to the top edge of the guide post 8 for opening and closing the channel in the guide post 8. In other embodiments, the outer cylinder 5 may further have a locking member (not shown) that can electrically or manually fix the outer cap 9 to the guide post 8 and electrically or manually release the outer cap 9.

On the other hand, the outer tub 5 may comprise at least one rack 52. The racks 52 may be disposed around the second annular wall 50 in a welded fashion. As shown in fig. 2, the second driving device 7 includes a power source 70 and a gear 72, the power source 70 is mechanically coupled to the gear 72, and the gear 72 engages the rack 52. By this, the second driving device 7 drives the outer cylinder 5 to rotate at a specific angle with respect to the axis a by the power output from the power source 70 through the meshing relationship between the gear 72 and the rack 52. In the present embodiment, the power source of the first driving device 6 and the power source 70 of the second driving device 7 are both motors.

As shown in fig. 1 to 5, in the present embodiment, the detecting device 2 includes a housing 20 and an elastic shielding member 22. The housing 20 has a receiving opening 24, the receiving opening 24 corresponding to the guide post 8 of the outer cylinder 5 in the second position (see fig. 5). The elastic shielding member 22 is disposed beside the receiving opening 24 and shields the receiving opening 24 in a movable manner. For example, the material of the elastic shielding member 22 may include silica gel. When the guide post 8 of the outer cylinder 5 moves to the receiving opening 24, the elastic shutter 22 may be pushed to temporarily deform the elastic shutter 22 so that the guide post 8 enters the housing 20. When the guide post 8 is removed from the housing 20, the elastic shielding member 22 is restored to its original position to shield the receiving opening 24 from the outside of the housing 20. In other embodiments, the elastic shielding member 22 can be opened manually or via the control device 3 shown in fig. 1.

The control device 3 includes a plurality of processing modules and software, and performs operations, storage, and control on data. The control device 3 may be provided with a dashboard 30 and keys 32 for an operator to operate.

In addition, the roasting and detecting system 100 may further comprise a stand 90 for supporting the inner tub 4 and the outer tub 5. The support 90 may be provided with rollers (not shown), and the support 90 does not rotate with the inner cylinder 4 and the outer cylinder 5 when the inner cylinder 4 and the outer cylinder 5 rotate.

Referring to FIG. 3, a partial cross-sectional view of a first operation of the roasting and inspection system 100 of FIG. 1 of the present invention is shown. The first annular wall 40 of the inner cylinder 4 forms a receiving space 44, and the first annular wall 40 forms a first opening 46, and the first opening 46 communicates with the receiving space 44. The inner cylinder 4 may be provided with a plurality of heating units, fan units, temperature measuring units, wind speed measuring units, etc. (not shown) as required. The heating unit may be a stove or an electronic heating stove for heating the coffee beans to a default temperature. The fan unit is used for blowing the object 400 (coffee beans) to be tested. The temperature measuring unit is used for measuring the heating temperature. The wind speed measuring unit may measure the wind speed in the accommodating space 44. The heating unit, the fan unit, the temperature measuring unit and the wind speed measuring unit are all common general knowledge of a person skilled in the art, and are not described in detail.

On the other hand, as shown in fig. 3, the second annular wall 50 has a second opening 54. The guide post 8 is disposed at the second aperture 54 and extends radially outwardly from the second annular wall 50 to form a channel 86 therein, the channel 86 being in communication with the second aperture 54.

In this embodiment, the detecting device 2 further includes a first detecting unit 10 and a second detecting unit 12. The first detecting unit 10 and the second detecting unit 12 are disposed in the housing 20 and are electrically connected to the control device 3 (see fig. 1 and 2).

The first detecting unit 10 is used for detecting a first property of the object 400. The first detection unit 10 may include an image capturing device (e.g., camera) 14 and a light source 16. For example, the image capturing device 14 of the first detecting unit 10 may capture an image of the object 400 (e.g. coffee beans in the embodiment) to be detected, and may transmit the image to the control device 3. The control device 3 can determine the color (first property) of the image, for example, by using the detected value of RGB (red, green and blue) or the detected value of gray scale. In one embodiment, the image capturing device 14 may be a digital camera generally available in the market or an industrial digital camera.

The second detecting unit 12 is configured to detect a second property of the object 400 to be detected, which is different from the first property. The second detection unit 12 may include a near infrared photodetector (Near Infrared Spectrometer, NIR). In more detail, the second detecting unit 12 of the detecting device 2 according to the present embodiment may comprise a probe-type or micro-type near infrared detector, so as to be mounted in the housing 20. The near infrared detector of the second detecting unit 12 is used for detecting the chemical property of the detected object or the identification of the specific component (second property), such as the sucrose content of the object 400 (coffee beans). Near Infrared (NIR) spectrum (near-infrared spectroscopy), which is a type of light wave and electromagnetic wave, is also an absorption spectrum of 780-2500nm, and is often involved in chemical bond interactions such as O-H, N-H and C-H in food applications, and also because of energy conversion between light and substances, vibration occurs when molecules absorb energy of near infrared light. However, not all the energy of the light is absorbed by the molecules, but the energy of the discontinuous light conforming to the specific molecules and energy levels is selected, so that the different molecules absorb the light with different wavelengths and can be used for qualitative and quantitative analysis of food. However, the values obtained by conventional chemical analysis are also required to be statistically regressive with the near infrared scanning spectrum. Thus, the detection device 2 of the present invention can detect a specific component (e.g., sucrose) by using such a principle. For example, the probe or mini Near infrared detector may be an excel 241NIR biomass sensor of EXNER Process equipment GMBH, a MATRIX-F Fourier Transform Near Infrared (FT-NIR) spectrometer of Syntpoint OU, a Pocket eagle-Near infrared (PH-NIR) series spectrometer of OTO Photonics.

The embodiments of the first detecting unit 10 and the second detecting unit 12 are merely examples. In other embodiments, the first detection unit 10 may comprise a near infrared photodetector, and the second detection unit 12 may comprise an image capturing device and a light source. In addition, the positions of the first detecting unit 10 and the second detecting unit 12 in the drawings of the present embodiment are only schematic, and the actual positions of the first detecting unit 10 and the second detecting unit 12 will be adjusted according to the actual requirements.

To confirm the correlation between the obtained signal and the component to be measured (e.g., sucrose), qualitative and quantitative analysis of the object 400 (coffee beans) to be measured of different varieties and different roasting degrees can be performed in advance using a near infrared photodetector. Thus, near infrared photodetectors are front-end tools for creating a database or evaluating the feasibility of analyzing a particular component (e.g., sucrose). For example, the pre-established database of near infrared photodetectors may be a desktop near infrared photodetector such as Spectra Star XT NIR Analyzer manufactured by Unity Scientific, mass. After creating the database with enough information, the operator can set the baking time, temperature, air volume, rotation speed and the like required by the objects 400 to be tested with different varieties and different baking degrees in advance by using the information. For example, information collected from multiple experiments may indicate that if low roast and first variety of beans are to be roasted, roasting is required at a first time and a first temperature; if the middle roast and the second variety of coffee beans are to be roasted, a second time and a second temperature are required to be roasted. However, in some embodiments, during roasting of the coffee beans, it may be distinguished into different time sections to roast at different temperatures in sections of different time lengths.

In addition, to obtain a large amount of data, a database may be built using the baking and detection system of the present invention. When the data is complete, the custom-made baking operation can be started. In addition, after the data are complete, the control device 3 can add an intelligent mode, automatically adjust the baking parameters according to the baking degree and sucrose information received in the baking process, customize and gradually fit the baking degree and flavor required by the operator.

The following table shows RGB values and gray scale values of the roasted coffee beans according to an embodiment of the present invention. The RGB values and the gray scale values are all in the range of 0 to 255.

Table one: color quantitative detection value of coffee beans with different roasting degrees

The following table two shows the analytical values of sucrose content of coffee beans of different roasting degree according to the embodiment of the present invention.

And (II) table: sucrose content of coffee beans with different roasting degree

The sucrose content in the coffee beans has a significant correlation with the aroma of the brewed coffee, which gradually decreases with the roasting degree during the roasting process, as can be seen from the above table.

The following describes the operation flow of the baking and detecting system 100 according to the present embodiment. Referring to fig. 3, first, in a receiving state, the first opening 46 of the inner cylinder 4 may be located above the drawing. At this point, the outer barrel 5 is in the first position, i.e., the second aperture 54 of the outer barrel 5 is aligned with the first aperture 46 of the inner barrel 4 in this embodiment. In other words, the control device 3 controls both the inner cylinder 4 and the outer cylinder 5 to be stationary, and communicates the first opening 46 with the second opening 54 of the outer cylinder 5 in the first position. At this time, the object 400 to be measured (e.g. coffee beans in this embodiment) can be poured from the guide column 8 of the outer cylinder 5 into the accommodating space 44 of the inner cylinder 4 through the second opening 54 of the outer cylinder 5 and the first opening 46 of the inner cylinder 4 in sequence.

Referring now to FIG. 4, therein is shown a partial cross-sectional view of a second operation of the roasting and inspection system 100 of FIG. 1 of the present invention. At this time, pouring of the object 400 to be measured is stopped and the cover 9 is closed, and the first driving device 6 shown in fig. 1 drives the inner cylinder 4 to continuously rotate along the axis a in the clockwise direction of the drawing to have the first path R1 (i.e., the rotation path), and simultaneously the baking operation can be performed on the object 400 to be measured in the inner cylinder 4. Parameters such as baking and rotation time, speed, heating temperature, wind power and the like can be customized by an operator in advance, or can be controlled by data stored in the control device 3 so as to obtain the desired baking degree, aroma and flavor of the object 400 to be tested. The baking step is a procedure well known to those skilled in the art, and will not be described in detail.

Referring now to FIG. 5, therein is shown a partial cross-sectional view of a third operation of the roasting and inspection system 100 of FIG. 1 of the present invention. After baking for a set period of time, the power source 70 of the second driving device 7 (shown in fig. 1) drives the outer cylinder 5 to rotate along the second path R2 from the original first position (fig. 4) to a second position (fig. 5). In detail, as shown in the direction of the drawing of fig. 5, in a released state, the power source 70 of the second driving device 7 drives the gear 72 to rotate in the reverse clock direction, and the gear 72 drives the rack 52 of the outer cylinder 5 to rotate in the clockwise direction. At this time, the guide post 8 of the outer cylinder 5 can be rotationally moved from above the inner cylinder 4 (i.e., about zero o 'clock in the drawing, the first position of the outer cylinder 5) to the right below the inner cylinder 4 (i.e., about four o' clock in the drawing, the second position of the outer cylinder 5) along the second path R2 clockwise along the axis a, i.e., the guide post 8 moves to the receiving port 24 of the detecting device 2, as shown in fig. 4. At this time, the guiding post 8 pushes the elastic shielding member 22 to temporarily deform the elastic shielding member 22, so that the guiding post 8 enters the housing 20, and the cover 9 pivoted to the top edge of one side of the guiding post 8 is automatically opened due to gravity. When the inner cylinder 4 continues to rotate and the first opening 46 of the inner cylinder is aligned with the second opening 54 of the outer cylinder 5, a small portion of the object 420 to be tested in the inner cylinder 4 falls from the guide column 8 into a transparent container 26 in the detecting device 2 due to the influence of centrifugal force and gravity. It can be seen that, since the first path R1 of the first opening 46 at least partially overlaps the second path R2 of the second opening 54 (i.e., a portion of the rotational path of the inner cylinder 4 passes through the second opening 54), when the first opening 46 and the second opening 54 are aligned, a small portion of the object to be measured 420 in the object to be measured 400 falls out of the inner cylinder 4 and falls into the detection device 2 adjacent to the second opening 54 when the outer cylinder 5 is in the second position via the channel 86 of the guide post 8. After a period of time (e.g. several seconds), or after it is determined that a certain number or weight of the objects to be tested 420 have fallen into the detecting device 2, the second driving device 7 may drive the outer cylinder 5 in the opposite direction to return to the original position, i.e. the outer cylinder 5 may return from the second position to the first position, so as to avoid that more objects to be tested 400 fall into the detecting device 2.

In addition, the control device 3 can also send out a signal or alarm to remind the operator when baking to the set period. The operator may make manual adjustments or assistance based on the information and/or alarms.

After a portion of the object to be tested 420 falls into the detecting device 2 for a short period of time (e.g., several seconds), a first detecting step (i.e., turning on the light source 16 and controlling the image capturing device 14 to capture an image) and a second detecting step (i.e., scanning and detecting with near infrared light by using the near infrared light detector of the second detecting unit 12) can be sequentially or simultaneously performed. That is, the first detection unit 10 and the second detection unit 12 are used to detect the part of the object to be measured 420 (most of the object to be measured 400 is still located in the inner cylinder 4) that falls stationary in the detection device 2. It should be noted that, since the current part of the object 420 is stationary, the detection results of the first detection unit 10 and the second detection unit 12 for the stationary part of the object 420 are significantly better in accuracy than the detection of the object 400 still under the rotary baking. Therefore, the image capturing device 14 of the detecting device 2 can achieve the capturing image effect required by the present invention without the need of a highly precise and expensive camera.

As described above, the first detecting unit 10 and the second detecting unit 12 can capture images and detect near infrared light to measure properties of a portion of the object 420. The RGB values or the gray-scale detection values of the part of the object 420 to be tested can be detected by capturing the image, and when the detection values are equal to or exceed a preset first threshold value, it can be indicated that the baking is completed (the desired baking degree is achieved). In addition, by detecting a specific component (e.g., sucrose) of the object 420 with near infrared light, the baking is completed (the desired flavor or aroma is achieved) when the detected value is equal to or exceeds a predetermined second threshold. It should be noted that, the operator can set in advance whether the two detection values respectively meet the first threshold value and the second threshold value to confirm that the baking is completed; or, the operator can set in advance that the baking is completed as long as the first threshold or the second threshold is met. In other words, the operator may set in advance that one of the baking degree and the flavor and fragrance required meets the standard, or that both the baking degree and the flavor and fragrance meet the standard.

When the control device 3 determines that the roasting step is completed, the operation of the inner tube 4 is stopped, and then, the roasted coffee beans are taken out to complete. In one embodiment, the baked objects 400 within the drum 4 may be removed in an automated manner. In other embodiments, the baked object 400 may be manually removed from the inner barrel 4.

If the control means 3 determines that the baking step has not been completed, another period of baking is required. For example, the control device 3 may calculate the time required for re-baking according to the difference between the two detected values and the first threshold and the second threshold. At this time, the inner tub 4 continues to operate and continues to bake during this period. The part of the object that was originally dropped into the inspection device 2 can then be manually or automatically removed from the inspection area (i.e., transparent container 26) and the release step can be performed again. The releasing step is to rotate the outer cylinder 5 to move the second opening 54 to the second position of the outer cylinder 5 shown in fig. 5, such that a part of the rotation path of the inner cylinder 4 (the first opening 46) corresponds to the second opening 54, and the receiving opening 24 of the detecting device 2 also corresponds to the guiding post 8 and the second opening 54. In this way, another portion of the object 400 can be dropped into the detecting device 2 through the first opening 46 and the second opening 54 for further detection. If the detected value is greater than or equal to at least one or both of the first threshold and the second threshold (i.e., the predetermined values are all met or one of them is met), it represents that the detection is passed. When the detection is acceptable, the rotation of the inner cylinder 4 is stopped, and the object 400 is taken out. If the detection does not meet at least one or both of the first threshold and the second threshold, a third baking operation may be performed again, and the above steps are performed until the detection meets the threshold.

In other embodiments, the operator is notified when the detection value does not meet the threshold. The operator can determine whether to perform the next baking operation by means of a manual determination.

Referring now to FIG. 6, a partial cross-sectional view of a first operation of a roasting and inspection system 200 according to a second embodiment of the present invention is shown. The present embodiment is substantially identical to the previous embodiment in terms of its structure, differing mainly in the design of the guide post 8'. In this embodiment, the two sides of the guiding post 8' may have different lengths, the left side 80 may be slightly longer than the right side 82, and the cover 9' is movably pivoted to the left side 80 of the guiding post 8 '. The outer cylinder 5 may further have a locking member (not shown) for automatically or manually fixing the outer cap 9 'to the guide post 8' or releasing the outer cap 9 'from the guide post 8'. In the present embodiment, at least one of the guiding post 8 'and the cover 9' may be transparent, so as to facilitate the first detection unit 10 and the second detection unit 12 penetrating the guiding post 8 'or the cover 9' to detect the object 400.

The baking and detecting method of the present embodiment is described below. First, as shown in fig. 6, the object 400 to be measured is placed into the accommodating space 44 of the inner cylinder 4 via the guide column 8 'of which the outer cover 9' has been opened.

Referring to fig. 7, a partial cross-sectional view of a second operation of the roasting and inspection system 200 of fig. 6 is shown. Then, the cover 9 'is closed and fixed to the guide post 8'. The drum 4 starts to rotate and the object 400 is baked for a predetermined time.

Referring to fig. 8, a partial cross-sectional view of a third operation of the roasting and inspection system 200 of fig. 6 is shown. After baking for a predetermined time, the outer cylinder 5 starts to rotate clockwise to a second position along the second path R2, and the guide post 8' of the outer cylinder 5 is guided into the detecting device 2. At this time, the inner cylinder 4 continues to rotate. Then, when the first opening 46 of the inner cylinder 4 is rotated to correspond to the second opening 54, the object 400 falls into the guiding post 8' from the inner cylinder 4. Because of the centrifugal force of rotation and the influence of gravity, the object 400 to be measured falls into the bottom of the guide column 8 '(i.e., on the inner side of the outer cover 9').

Then, the first detection step and the second detection step may be sequentially or simultaneously performed to detect the object 400 to be detected. The first detection step and the second detection step in this embodiment are similar to those in the previous embodiment, and thus are not described again. In this embodiment, if the detected value meets the predetermined threshold value, the outer cylinder 5 returns to the first position, and the detected object in the guiding column 8' falls into the accommodating space 44 of the inner cylinder 4 through the second opening 54 of the outer cylinder 5 and the first opening 46 of the inner cylinder 4. Then the inner cylinder 4 can stop rotating to finish the baking operation. If the detected value does not meet the predetermined threshold value, the outer cylinder 5 returns to the first position, and the detected object in the guiding column 8' falls into the accommodating space 44 of the inner cylinder 4 through the second opening 54 of the outer cylinder 5 and the first opening 46 of the inner cylinder 4. Then, the inner drum 4 continues to be spin baked for another predetermined period of time. Then, the release and detection steps are performed. That is, the outer tube 5 is rotated so that the partial object 400 to be measured enters the guide column 8', and the partial object to be measured is detected in the detecting device 2. In the present embodiment, it should be noted that part of the objects to be measured 420 are placed in the guiding columns 8' for measurement, and can be returned to the inner cylinder 4 by the reverse rotation of the outer cylinder 5, so that all the objects 400 can be accommodated in the baking device 1 during the baking and detecting operations. Thus, since the objects 400 are all in the baking device 1, external influence can be effectively avoided, and the detection accuracy is improved.

In addition, in the present embodiment, due to the design of different heights on the two sides of the guiding post 8', when the outer cylinder 5 is located at the second position, the transparent cover 9' can be parallel to the bottom surface of the detecting device 2, so that the image capturing device 14 of the first detecting unit 10 and the second detecting unit 12 can be easily aligned to the transparent cover 9, which is further beneficial to the accuracy of the detection of the first detecting unit 10 and the second detecting unit 12.

Fig. 9 is a perspective view of a baking and inspection system 300 according to a third embodiment of the present invention. Fig. 10 is a partial cross-sectional view of a first action of the roasting and inspection system 300 of fig. 9 of the present invention. The present embodiment is similar to the embodiment shown in fig. 1 to 5, and therefore the description thereof will not be repeated.

In this embodiment, the outer cylinder 5' does not rotate with respect to the shaft center a; the outer cylinder 5 'includes a second annular wall 50, a hollow first guiding post 8a and a hollow second guiding post 8b, and the second annular wall 50 of the outer cylinder 5' has a second opening 54 and a third opening 56. The first guide post 8a and the second guide post 8b are respectively communicated with the second opening 54 and the third opening 56 shown in fig. 10, and are respectively disposed on the second annular wall 50 and extend radially outwards from the second annular wall 50.

In this embodiment, the first guiding post 8a comprises an outer cover 9. As shown in fig. 10, when the outer cover 9 is opened, the object 400 to be measured can be put into the inner cylinder 4 from the first guide column 8 a. In addition, the inner end of the second guiding post 8b may comprise a gate 84, and the outer end of the second guiding post 8b is connected to the detecting device 2. The control device 3 can control the movement of the gate 84, and thus the opening and closing of the third opening 56 of the second guide post 8 b. In other words, when the shutter 84 is closed, the object 400 to be measured cannot enter the second guide column 8b from the inner tube 4. When the shutter 84 is opened and the first opening 46 of the inner cylinder 4 corresponds to the third opening 56 of the outer cylinder 5', the object 400 to be measured can enter the second guiding column 8b from the inner cylinder 4.

The baking and detecting method of the present embodiment is described below. As shown in fig. 10, the outer cover 9 of the first guide post 8a may be opened first, and the second opening 54 of the first guide post 8a corresponds to the first opening 46 of the inner cylinder 4. Next, the object 400 to be measured is put into the inner cylinder 4 from the outer cover 9 of the first guide column 8 a. At this time, the shutter 84 at the inner end of the second guide post 8b is in a closed state.

Fig. 11 is a partial cross-sectional view of a second action of the roasting and inspection system 300 of fig. 9 of the present invention. As shown in fig. 11, the inner drum 4 is started to start rotating the inner drum 4 along the first path R1 and baking the object 400 to be tested.

Fig. 12 is a partial cross-sectional view of a third action of the roasting and inspection system 300 of fig. 9 of the present invention. After a certain period of time, the shutter 84 of the second guiding column 8b can be opened for a short period of time, and when the first opening 46 of the inner cylinder 4 corresponds to the third opening 56, the part of the object 420 to be measured falls into the second guiding column 8b. Then, the part of the object 420 to be tested falls into the transparent container 26 of the detecting device 2 via the second guiding column 8b. Then, the shutter 84 is closed to prevent the excessive objects 400 from falling into the second guide column 8b.

At this time, the first detecting unit 10 and the second detecting unit 12 may detect the stationary part of the object 420 located in the transparent container 26 simultaneously or sequentially (respectively). When the detected value meets the threshold value, the operation of the inner cylinder 4 is stopped and the baking operation is completed. When the detection is not in accordance with the threshold value, the operation of the inner cylinder 4 is continued, and the baking operation is continued. It should be noted that, when the detection does not meet the threshold, the object 400 that is detected in the detection device 2 can be manually or automatically removed from the detection device 2, so that the transparent container 26 can accommodate a new object 400 to be detected.

According to one embodiment of the present invention, a baking and detecting method includes the following steps. The baking and inspection systems 100, 200 described above are provided. A receiving step is performed, wherein the inner cylinder 4 and the outer cylinder 5 are stationary, and the first opening 46 of the inner cylinder 4 corresponds to the second opening 54 of the outer cylinder 5 at a first position, and a plurality of objects 400 are placed into the accommodating space 44 of the inner cylinder 4 through the first opening 46 and the second opening 54. The inner tub 4 is rotated and the object 400 is baked during a first period. A releasing step is performed to move the outer cylinder 5 to move the second opening 54 to a second position, so that a portion of the rotation path of the inner cylinder 4 corresponds to the second opening 54, and the receiving opening 24 of the detecting device 2 corresponds to the second opening 54, so that a portion of the object 420 to be detected falls into the detecting device 2 through the first opening 46 and the second opening 54. The outer cartridge 5 is moved back to the first position. A portion of the object under test 420 is inspected to generate an inspected value. When the detected value is equal to or exceeds a threshold value, the inner cylinder 4 stops rotating and baking is stopped.

The baking and detecting method of the present embodiment further includes: when the detected value is smaller than the threshold value, the inner cylinder 4 continues to rotate and is baked for a second period. A release step is performed to move the outer cylinder 5 to move the second opening 54 to the second position so that another portion of the object 400 falls into the detection device 2 through the first opening 46 and the second opening 54. Another portion of the object 400 is detected to produce another detected value. When the other detection value is equal to or exceeds the threshold value, the inner drum 4 stops rotating and the roasting is stopped.

In view of the foregoing, the present invention provides a roasting and inspection system 100, 200 and method for roasting and inspecting an agricultural crop (e.g., coffee beans). In one embodiment, the outer cylinder 5 of the baking and detecting system 100, 200 can rotate relative to the axis a to enable the object 400 to be tested to enter the inner cylinder 4 for baking or enable the object 400 to be tested to move out of the inner cylinder 4 and enter the detecting device 2 for detection. The baking and inspection systems 100, 200 and methods for the stationary object 400 in such a fully automated manner can quickly obtain a baked good of a quality (e.g., baking level or aroma) desired by an operator at low cost and quickly without the need for human labor. Meanwhile, through scientific detection, huge losses caused by human errors are avoided. Moreover, the object 400 to be tested is detected in the device to be tested, so that the interference of high heat, dynamic and moisture of the inner cylinder 4 during baking or the interference of the outside can be avoided, and the high-quality image can be captured, thereby effectively improving the accuracy of detection.

In another embodiment, the outer cylinder 5' of the baking and detecting system 300 does not rotate relative to the axis a, but has two guiding columns 8a and 8b that can be opened and closed respectively to control the entry and exit of the object 400 to be tested, so that the effect of the present invention can be achieved.
