Description

Baking and inspection system

This creation is about a roasting and inspection system, especially a coffee bean roasting and inspection system.

According to statistics, Chinese people can consume 2.85 billion cups of coffee a year, making my country's coffee beverages annual output value of 75 billion yuan. The phenomenon that cafes have sprung up in the streets and alleys in recent years is enough to show that while people's demand for coffee is increasing, quality is also one of the indispensable factors. In other words, people's preference has been improved from the canned coffee available from general convenience stores to the expectation of a cup of high-quality freshly brewed coffee carefully brewed by hand from a cafe. However, to brew a great cup of coffee, the coffee beans themselves and how they are roasted are the most important key.

In the process of general roasting coffee beans, the conventional equipment can only record its firepower, wind speed, wind temperature, boiler speed, temperature difference and humidity as the basis for determining the roasting time. In general roasting practices, a small amount of coffee beans are taken out with a bean stick, and the color is observed with the naked eye, or the roasting is judged by experience based on the popping sound or smell during roasting. However, this method of judging coffee beans roasting by using empirical rules is too subjective and cannot be detected and judged by scientific and quantitative methods. Moreover, this traditional method requires an experienced coffee bean roaster to operate it, which makes the cost too high and does not meet the mass demand of the public.

Therefore, it is necessary for the industry to provide a baking and inspection system for fully automatic baking and inspection of an agricultural crop.

The reason is that this creation provides a baking and inspection system to automatically bake and inspect an object to be tested.

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 moves relative to the inner cylinder 4 by the second external force, so that the outer cylinder 5 can be located at least at a first position And a second position. In this embodiment, the outer cylinder 5 is subjected to a second external force and also rotates around the inner cylinder 4 along the same axis A as when the inner cylinder 4 rotates. In this embodiment, the outer cylinder 5 rotates in the same direction around the inner cylinder 4. However, in other embodiments, the outer cylinder 5 may rotate around the inner cylinder 4 in a reverse manner. In addition, a sliding rail and/or a bearing structure (not shown) may be included between the inner cylinder 4 and the outer cylinder 5 to enable the inner cylinder 4 and the outer cylinder 5 to move smoothly relative to each other.

The inner cylinder 4 disclosed in this embodiment is cylindrical, and the inner cylinder 4 includes a first annular wall 40 and two bottom covers 42. Two bottom covers 42 are respectively disposed on opposite ends of the first annular wall 40 to close the two ends of the first annular wall 40.

As shown in FIGS. 1 to 5, in this embodiment, the detection device 2 includes a housing 20 and an elastic shield 22. The housing 20 has a receiving opening 24 corresponding to the guiding post 8 when the outer cylinder 5 is in the second position (see FIG. 5). The elastic shielding member 22 is arranged beside the receiving opening 24 to cover the receiving opening 24 in a movable manner. For example, the material of the elastic shield 22 may include silicone. When the guide post 8 of the outer cylinder 5 moves to the receiving opening 24, the elastic shield 22 can be pushed to temporarily deform the elastic shield 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 will return to its original shape (return to its original position) to cover the receiving opening 24, so that the interior of the housing 20 will not be exposed to the outside. In other embodiments, the elastic shield 22 can also be opened manually or by the control device 3 shown in FIG. 1.

The control device 3 includes multiple processing modules and software to perform calculation, storage and control of data. The control device 3 can be provided with a dashboard 30 and buttons 32 for the operator to operate.

An accommodating space 44 is formed in the first annular wall 40 of the inner cylinder 4, and a first opening 46 is formed in the first annular wall 40, and the first opening 46 is communicated with the accommodating space 44. Several heating units, fan units, temperature measurement units, wind speed measurement units, etc. (not shown) can also be provided inside and outside the inner cylinder 4 according to requirements. The heating unit can be a stove or an electronic heating stove for heating the coffee beans to a preset temperature. The fan unit is used for blowing the object 400 (coffee beans) under test. The temperature measuring unit is used to measure the heating temperature. The wind speed measuring unit can measure the wind speed in the accommodating space 44. The heating unit, the fan unit, the temperature measurement unit and the wind speed measurement unit are common knowledge of those skilled in the art, so they will not be repeated here.

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 opening 54 and extends radially outward from the second annular wall 50 to form a channel 86 therein, and the channel 86 communicates with the second opening 54.

In this embodiment, the detection device 2 further includes a first detection unit 10 and a second detection unit 12. The first detection unit 10 and the second detection unit 12 are both arranged in the housing 20, and are respectively electrically connected to the control device 3 (see FIGS. 1 and 2).

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

The second detection unit 12 is used to detect a second property that is different from the first property of the object 400 under test. The second detection unit 12 may include a Near Infrared Spectrometer (NIR). In more detail, the second detection unit 12 of the detection device 2 disclosed in this embodiment may include a probe type or a miniature near-infrared light detector to facilitate the device in the housing 20. The near-infrared light detector of the second detection unit 12 is used to detect the identification of the chemical properties or specific components (second properties) of the detected object, such as the sucrose content of the object 400 (coffee beans) to be detected. Near-infrared spectroscopy (near-infrared spectroscopy) is a kind of light wave and electromagnetic wave. It is also an absorption spectrum with a wavelength of 780-2500 nm. Food applications often involve the interaction of chemical bonds such as OH, NH, and CH. It is also due to the interaction between light and matter Energy conversion, when molecules absorb the energy of near-infrared light, they will vibrate. But not all the energy of light will be absorbed by molecules, but the energy of discontinuous light that meets its unique molecules and energy levels will be selected, so different molecules will absorb light of different wavelengths, which can be used for qualitative and quantitative analysis of food. However, the values obtained by traditional chemical analysis are also required to perform statistical regression analysis with the near-infrared scanning spectrum. Therefore, the detection device 2 of the present invention uses this principle to detect specific components (for example, detection of sucrose). For example, the probe-type or miniature near-infrared light detector can be EXNER Process equipment GMBH’s EXcell 241 NIR biomass sensor, Syntpot OÜ’s MATRIX-F Fourier Transform Near Infrared (FT-NIR) spectrometer, OTO Photonics (Taiwan Supermicro optical) Eagle's pocket - near infrared ^{TM (pocket Hawk - near-infrared} TM, PH-NIR) spectrometers.

The foregoing embodiments of the first detection unit 10 and the second detection unit 12 are only examples. In other embodiments, the first detection unit 10 may include a near-infrared light detector, and the second detection unit 12 may include an image capturing device and a light source. In addition, the positions of the first detection unit 10 and the second detection unit 12 in the drawings of this embodiment are only for illustration, and the actual positions of the first detection unit 10 and the second detection unit 12 will be adjusted according to actual needs.

In order to confirm the correlation between the obtained signal and the desired measurement component (such as sucrose), the near-infrared light detector can be used in advance to qualitatively and determine the object 400 (coffee beans) of different varieties and different roasting levels. Quantitative analysis. Therefore, the near-infrared light detector is used as a front-end tool for establishing a database or evaluating the feasibility of analyzing a specific component (such as sucrose). For example, the near-infrared light detector with a pre-built database may be a desktop near-infrared light detector, such as the Spectra Star XT NIR Analyzer produced by Unity Scientific, Massachusetts, USA. After a database with sufficient information is created, the operator can use the information to pre-set the baking time, temperature, air volume, rotation speed, etc. of the object 400 to be tested for different varieties and different baking levels. For example, the information collected through many experiments shows that if you need to roast low-roasted and first-variety coffee beans, you need to roast under the conditions of a first time and a first temperature; For middle roast and second varieties of coffee beans, it takes a second time and a second temperature to roast. However, in some embodiments, the roasting of coffee beans can be divided into different time sections, so as to roast at different temperatures in the sections of different time lengths.

In addition, in order to obtain a large amount of data, the baking and inspection system of this creation can be used to establish a database. When the data is complete, you can start making customized baking operations. In addition, when the data is complete, the control device 3 can add a smart mode to adjust the baking parameters according to the changes in the baking degree and sucrose information received during the baking process, customize and gradually fit the operator’s needs Degree of baking and flavor.

Table 1 below shows the RGB values and grayscale values of the dark, medium and light roasted coffee beans in an embodiment of the creation. The range of RGB value and grayscale value is 0 to 255.

Table 2 below is the analysis value of the sucrose content of coffee beans with different roasting degrees according to an embodiment of the creation. Sample name Sampling grams (g) Constant volume (mL) Instrumental analysis value sucrose (g/mL) Concentration of sucrose in the sample (g/100g) Light roasted coffee beans 1.94 10 0.00088314 0.46 Medium roasted coffee beans 1.95 10 0.00059407 0.30 Deep roasted coffee beans 2 10 0 0.00 Table 2. Sucrose content of coffee beans with different roasting degrees

The sucrose content in coffee beans has a significant correlation with the aroma of the coffee after brewing. During the roasting process, the internal sucrose content will gradually decrease with the roasting degree. This trend can also be seen from the above table.

The following describes the operation process of the baking and inspection system 100 of this embodiment. Please refer to FIG. 3. First, in a receiving state, the first opening 46 of the inner cylinder 4 can be located above the drawing. At this time, the outer cylinder 5 is in the first position, that is, the second opening 54 of the outer cylinder 5 is aligned with the first opening 46 of the inner cylinder 4 in this embodiment. In other words, the control device 3 controls both the inner tube 4 and the outer tube 5 to be stationary, and makes the first opening 46 communicate with the second opening 54 of the outer tube 5 at the first position. At this time, the object 400 (such as coffee beans in this embodiment) can be passed from the guide post 8 of the outer tube 5 through the second opening 54 of the outer tube 5 and the first opening 46 of the inner tube 4 in sequence. Pour into the accommodating space 44 of the inner cylinder 4.

Please refer to FIG. 4, which is a partial cross-sectional view of the second action of the baking and inspection system 100 in FIG. At this time, stop pouring the object 400 to be tested and close the outer cover 9. 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 a first path R1 ( That is, the rotation path), and at the same time, the object to be tested 400 in the inner cylinder 4 can be baked. Among them, the parameters such as baking and rotating time, speed, heating temperature, wind power, etc. can be customized by the operator in advance, or they can be controlled through the data stored in the control device 3, in order to obtain 400 test objects. Desired baking degree, aroma and flavor. This baking step is a process well known to those skilled in the art, so it will not be repeated.

Please refer to FIG. 5, which is a partial cross-sectional view of the third action of the baking and inspection system 100 in FIG. When the baking reaches the set time, the power source 70 of the second driving device 7 (as 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 (Figure 5). In detail, as shown in the direction of the drawing in FIG. 5, in a released state, the power source 70 of the second driving device 7 drives the gear 72 to rotate in a counterclockwise direction, and the gear 72 then drives the rack 52 of the outer cylinder 5 to Turn clockwise. At this time, the guide post 8 of the outer cylinder 5 can be moved clockwise along the axis along the second path R2 from above the inner cylinder 4 as shown in FIG. 4 (that is, the position at about zero o'clock in the drawing, the first position of the outer cylinder 5). A rotates and moves to the lower right of the inner cylinder 4 (that is, the position at about four o'clock in the drawing, the second position of the outer cylinder 5), that is, the guide column 8 moves to the receiving port 24 of the detection device 2. At this time, the guide post 8 pushes the elastic shield 22 to temporarily deform the elastic shield 22, so that the guide post 8 enters the housing 20, and the outer cover 9 pivotally connected to the top edge of the guide post 8 Automatically open due to gravity. When the inner cylinder 4 continues to rotate and its first opening 46 is aligned with the second opening 54 of the outer cylinder 5, a small part of the object to be tested 420 in the inner cylinder 4 will self-guide the column 8 due to the influence of centrifugal force and gravity. Drop into a transparent container 26 in the detection device 2. It can be seen that since the first path R1 of the first opening 46 is at least partially overlapped with the second path R2 of the second opening 54 (that is, a part of the rotation path of the inner cylinder 4 passes through the second opening 54), Therefore, when the first opening 46 and the second opening 54 are aligned, a small part of the object to be tested 420 in the object to be tested 400 will fall out of the inner cylinder 4 and fall into the neighboring area through the channel 86 of the guide column 8. It is located in the detection device 2 of the second opening 54 when the outer cylinder 5 is in the second position. After a period of time (for example, a few seconds), or after it is determined that a certain number or weight of the test object 420 has fallen into the detection device 2, the second driving device 7 can drive the outer cylinder 5 back to the original position, that is, the outer cylinder 5 can return from the second position to the first position to prevent more objects 400 to be tested from falling into the detection device 2.

In addition, when the baking reaches the set period, the control device 3 can also send out a signal or alarm to remind the operator. The operator can manually adjust or assist according to the message and/or alarm.

When part of the test object 420 falls into the detection device 2 for a short period of time (for example, a few seconds), a first detection step can be performed sequentially (ie, separately) or simultaneously (turn on the light source 16 and control the image capture device 14 to capture Image) and a second detection step (using the near infrared light detector of the second detection unit 12 to scan and detect with near infrared light). That is, the first detection unit 10 and the second detection unit 12 are used to detect the stationary part of the test object 420 (most of the test objects 400 are still located in the inner cylinder 4) falling into the detection device 2. It should be noted that since some of the objects to be tested 420 are currently in a static state, the detection results of the first detecting unit 10 and the second detecting unit 12 for the stationary part of the objects to be tested 420 are compared with those of the objects to be tested that are still being rotated. The detection of the object 400 will obviously have better accuracy. Therefore, the image capturing device 14 of the detection device 2 does not require a highly sophisticated expensive camera to achieve the image capturing effect required in this case.

As described above, the first detection unit 10 and the second detection unit 12 can measure the properties of a part of the object to be tested 420 by capturing images and detecting near-infrared light. The RGB value or grayscale detection value of part of the object to be tested 420 can be detected by capturing the image. When the detection value is equal to or exceeds a preset first threshold, it means that the baking has been completed (all the results have been reached). Desire baking degree). In addition, the near-infrared light can be used to detect the detection of a specific component of the object 420 (such as sucrose). When the detection value is equal to or exceeds a preset second threshold, it can represent that the baking has been completed (The desired flavor or aroma has been achieved). It should be noted that the operator can set in advance whether the two detection values must meet the first threshold and the second threshold respectively before the baking is considered complete; or, the operator can set in advance as long as the first threshold or The second threshold value can be deemed to be completed. In other words, the operator can pre-set as long as one of the desired baking degree and flavor aroma meets the standard, or both the baking degree and flavor aroma must meet the standard.

When the control device 3 determines that the roasting step is completed, the operation of the inner cylinder 4 can be stopped, and then the roasted coffee beans are taken out to complete. In one embodiment, the baked object 400 in the inner cylinder 4 can be taken out in an automatic manner. In other embodiments, the baked object 400 can be taken out from the inner cylinder 4 manually.

If the control device 3 determines that the baking step has not been completed, another period of baking is required. For example, the control device 3 can calculate the time required for rebake according to the difference between the two detection values and the first threshold and the second threshold. At this time, the inner cylinder 4 will continue to operate and continue to bake during this period. After that, part of the objects that have been tested that originally fell into the detection device 2 can be manually or automatically removed from the detection area (that is, the transparent container 26), and the release step can be performed again. The release step is as described above, the outer cylinder 5 is rotated to move its second opening 54 to the second position of the outer cylinder 5 shown in FIG. 5, so that a part of the rotation path of the inner cylinder 4 (first opening The hole 46) corresponds to the second opening 54 and the receiving opening 24 of the detection device 2 also corresponds to the guiding post 8 and the second opening 54. In this way, another part of the object 400 can fall into the detection device 2 through the first opening 46 and the second opening 54 to perform another detection. If the detected value is greater than or equal to at least one or both of the first threshold value and the second threshold value (that is, whether the above-mentioned preset setting is to meet all or one of them meets), it means that the detection is passed. When the test is qualified, the rotation of the inner cylinder 4 can be stopped, and the object 400 can be taken out. If the detection still does not meet at least one or both of the first threshold value and the second threshold value, a third baking operation can be performed, and the above steps can be continued until the detection meets the threshold value.

In other embodiments, when the detected value does not meet the threshold value, the operator will be notified. The operator can decide whether to proceed with the next baking operation by manual judgment.

Another embodiment of this creation is introduced below. Please refer to FIG. 6, which is a partial cross-sectional view of the first action of the baking and inspection system 200 of the second embodiment of the creation. The structure of this embodiment is substantially the same as the previous embodiment, and the difference is mainly in the design of the guide post 8'. In this embodiment, the two sides of the guide post 8'can have different lengths. The left side 80 shown in the figure can be slightly longer than the right side 82, and the outer cover 9'is pivotally connected to the guide post 8'in a movable manner. 80 on the left. The outer cylinder 5 may additionally have a locking member (not shown), which can automatically or manually fix the outer cover 9'on the guide post 8', or release the fixation of the outer cover 9'on the guide post 8' . In this embodiment, at least one of the guide post 8'and the outer cover 9'may be transparent to facilitate the first detection unit 10 and the second detection unit 12 to penetrate the guide post 8'or the outer cover 9' The object 400 is detected.

The baking and detection methods of this embodiment are described below. First, as shown in FIG. 6, the object 400 to be tested is put into the accommodating space 44 of the inner cylinder 4 through the guide post 8 ′ with the outer cover 9 ′ opened.

Please refer to FIG. 7, which is a partial cross-sectional view of the second action of the baking and inspection system 200 of FIG. 6. Then, close the outer cover 9'and fix it on the guide post 8'. The inner cylinder 4 starts to rotate and bake the object 400 in a predetermined time.

Please refer to FIG. 8, which is a partial cross-sectional view of the third action of the baking and inspection system 200 of FIG. 6. After baking for a predetermined time, the outer cylinder 5 starts to rotate clockwise and follows the second path R2 to the second position, and the guide post 8 ′ of the outer cylinder 5 is guided into the detection device 2. At this time, the inner cylinder 4 will continue to rotate. Then, when the first opening 46 of the inner cylinder 4 corresponds to the second opening 54 during rotation, the object 400 to be tested will fall from the inner cylinder 4 into the guide post 8'. Due to the influence of the centrifugal force of rotation and gravity, the object 400 to be tested will fall into the bottom of the guide post 8'(ie, on the inner side of the outer cover 9').

Then, the first detection step and the second detection step can be performed sequentially or simultaneously to detect the object 400 under test. The first detection step and the second detection step of this embodiment are similar to the previous embodiment, so they will not be repeated. In this embodiment, if the detection meets the predetermined threshold value, the outer tube 5 will return to the first position, and the detected object in the guiding column 8'will pass through the second opening 54 of the outer tube 5 and the inner tube 4 The first opening 46 falls into the accommodating space 44 of the inner cylinder 4. Then the inner cylinder 4 can stop rotating to complete the baking operation. If the detection does not meet the predetermined threshold value, the outer cylinder 5 will return to the first position, and the detected object in the guiding column 8'will pass through the second opening 54 of the outer cylinder 5 and the first opening of the inner cylinder 4 46 and fall into the accommodating space 44 of the inner cylinder 4. Then, in another predetermined period of time, the inner cylinder 4 continues to rotate and bake. After that, the aforementioned release and detection steps are performed. That is, the outer cylinder 5 is rotated so that the part of the object 400 to be tested enters the guide column 8 ′, and the part of the object to be tested is detected in the detection device 2. In this embodiment, it should be noted that part of the object to be tested 420 is placed in the guide column 8'for measurement, and can be returned to the inner tube 4 by the reverse rotation of the outer tube 5, so All the objects 400 can be contained in the baking device 1 during baking and inspection operations. In this way, since the objects 400 are all in the baking device 1, external influences can be effectively avoided, thereby improving the accuracy of detection.

Move the outer cylinder 5 back to the first position. Part of the object to be tested 420 is detected to generate a detection value. When the detection value is equal to or exceeds a threshold value, the inner cylinder 4 stops rotating and stops baking.

The baking and detection method of this embodiment further includes: when the detection value is less than the threshold value, the inner cylinder 4 continues to rotate and the baking is performed in a second period. The release step is performed to move the outer cylinder 5 to move the second opening 54 to the second position, so that another part of the object 400 falls into the detection device 2 through the first opening 46 and the second opening 54. The other part of the object 400 is detected to generate another detection value.
