Description

Coffee Bean Stir-Fryer {COFFEE BEANS ROASTING MACHINE}

The present invention relates to a coffee bean fryer, and is particularly small and can be easily used in coffee shops and homes to remove noise and smoke, to visually check the roasting process of the beans, and to roast beans optimally. And, it relates to a coffee bean roaster that can be easily used automatically or manually even without knowledge or experience in beans.

In general, when coffee is roasted at high temperatures, the chemical changes occur to taste and aroma, and the coffee beans do not feel the aroma and taste at all. Therefore, the taste of coffee varies depending on the variety of beans, but the root is formed during the roasting process, so the roasting procedure and technique are very important.

However, in recent years, it is easy to improve the quality of coffee beans by roasting the beans after they have been roasted with advanced facilities and technology in large-scale factories. And lost incense.

In other words, after roasting, the original taste and aroma were lost.

This problem could be solved by purchasing raw beans and roasting them directly, but the coffee beans roaster introduced until recently took up a lot of space due to its large volume and weight, and consumed a lot of power, and almost skilled technicians could operate it. There was discomfort. In addition, in this case, there was also a problem in that the technique for roasting the beans should be mastered in advance.

This problem could be solved somewhat by the coffee bean roaster disclosed in patent application No. 2000-27797 filed by the applicant.

Coffee beans roaster according to the prior art as shown in Figure 1 is a perspective means for visually confirming the roasting process of the beans, the shell 14, coffee beans 16 and the measuring vessel 18 The front support plate 10 having the respective receiving holes 19A, 19B, and 19C to be installed, the supply means 22 for bean input, and the bean discharge hole 23 are placed on the second operating member 24D. A rear support plate having a discharge means 24 for opening and closing the discharge door 24C operated by the discharge door 24 and first and second driving members 26 and 28 installed on the first and second mounting brackets 29A and 29B. 20) and the drum chamber 32, which is installed between the front support plate 10 and the rear support plate 20, is grounded to be rotatable by the first drive member 26, and roasts the beans. Upon completion, a cooling means 34 for cooling the drum chamber 32 is provided on both side inclined surfaces 35 and the drum cover member 30 and the drum chamber 32. A heating means 40 installed on the rear support plate 20 so as to be positioned to heat the inside of the drum chamber 32, and installed on the rear support plate 20 so as to be located inside the drum chamber 32; The temperature sensor 50 to sense the temperature inside the chamber 32 and the drum cover member 30 is installed on one side of the exhaust gas generated in the drum chamber 32 to filter and discharge it. The gas discharge means 60 and the beans discharged from the drum chamber 32 are installed on the rear support plate 20 so that the beans are discharged evenly into the bean tray 16, and by the second driving member 28. The transfer conveyor 70 is operated, and is installed on the front support plate 10 is composed of a control means 80 for controlling the roasting process of the beans.

The coffee beans roaster according to the prior art configured as described above is controlled by the control means 80, as shown in Figures 1 to 2b, so that it is easy to roast without the expertise of roasting beans in the home or business It is possible to provide a convenient effect that can be roasted to your liking.

However, coffee beans roaster according to the prior art as described above has the following problems.

That is, as shown in Figs. 1 to 2a, the see-through window 12C, which is intended to cover the see-through hole 12A of the front support plate 10 of the scrambler, was installed in a fitting manner by a plurality of support brackets 12B. Therefore, the viewing window 12C was not in close contact with the front support plate 10, and there was a problem that the exhaust gas such as smoke leaked into the gap during roasting of the beans, and the detachable / mountability of the parts such as the exterior cover and the viewing window 12C. There was a problem of deterioration.

On the other hand, the drum cover member 30 according to the prior art, as shown in Fig. 1 and 2b, the side plate is formed to be inclined inward, respectively, so that the inclined surface 35 is formed, the beans discharged from the drum chamber 32 There is a problem that the shell of the stack is not discharged to the shell 14, the inside of the inclined surface (35).

In addition, the roasted beans have to be cooled quickly to obtain their unique taste and aroma. However, the cooling means 34 of the roaster according to the prior art is configured such that the third operating member 34D is operated by the control means 80 to simply open and close the air inlet hole 34A with the cooling door 34C. Because of this, the rapid cooling of the roasted beans was difficult.

That is, since the air inlet hole 34A was simply opened to the cooling door 34C during cooling, the external air could not be quickly introduced into the drum chamber 32, so that the cooling was not quick.

On the other hand, since the temperature sensor 50 according to the prior art was installed to measure only the internal temperature of the drum chamber 32, the temperature of the bean itself heated to the roasting temperature by the heating means 40 cannot be measured. There was a problem that the beans are burned. That is, in the related art, when the temperature inside the drum chamber 32 sensed by the temperature sensor 50 reaches the roasting temperature, for example, 320 ° C., the power applied to the heating means 40 is cut off, and thus the drum When the temperature inside the chamber 32 is detected to be lower than the set value, the heating means 40 is configured to apply power again, so that the heating means 40 is turned on / off irrespective of the temperature of the coffee beans itself. 32) Since the inside was heated, there was a problem that the beans were burned by the high temperature, and the life of the halogen lamp used as the heating means 40 was reduced.

In addition, since the gas discharge means 60 according to the prior art discharged the smoke generated during roasting of the beans, it was not possible to remove the exhaust gas, that is, smoke, which caused a problem that the smoke pollutes the room, In the operation of the blower fan 62, the shell of the beans was discharged to the outside through the discharge pipe 64, and the oil contained in the discharged smoke had a problem of contaminating the room.

On the other hand, the coffee beans roaster according to the prior art as described above was able to operate even if the amount of beans that can be roasted at a time, so the malfunction of the roaster due to the excess capacity was concerned, the problem that the beans are not roasted evenly In case of continuous use, the internal temperature of the machine could be operated in a state where the temperature was raised, and the breaker was concerned.

In addition, the coffee bean coffee roaster according to the prior art does not have a function of storing and displaying the total number of times of use of the roaster or the total amount of use (the amount of beans measured by the electronic weighing machine 90) and the like. There was a problem that it is difficult to manage the elements efficiently.

The present invention is devised to solve the problems of the prior art as described above, the technical problem of the present invention is to change the installation structure of the see-through window and the cover member and the outer cover is installed on the front support plate of the stirrup, such as the see-through window and the cover member It can improve the desorption / mountability of the beans, quickly cool the roasted beans, and control the heating means based on the measured temperature of the beans to prevent the beans from burning during roasting of the beans. It is possible to remove the smoke by burning the exhaust gas discharged from the chamber, and to provide a means for removing the oil contained in the smoke.

In addition, another technical problem of the present invention is to provide an error message when an error occurs in the fryer, and to provide a means for protecting the fryer by displaying the total number of times used or the total amount of roasted beans.

The control means 80 is configured to turn off the heating means 40 when the temperature detected by the coffee bean temperature sensor 50B is 235 ° C. or higher in a state where the amount of beans supplied is 650-1200 g. Can be configured.

The action of the temperature sensor 50 and the bean temperature sensor 50B is that the microcomputer 860 multi-steps the temperature inside the drum chamber 32 (1 st roast temperature, 2 st roast temperature, 3 st roast temperature). It is made organically during the control.

In addition, the control means 80 generates an error message when the weight of the coffee beans input from the electronic weighing machine 90 is greater than or equal to a set value, for example, 1 kg, cuts off power, and stops the operation. The heating means 40 ), If an error occurs in the temperature sensor 50 or the coffee bean temperature sensor 50B, an error message is generated and the operation is stopped, and a start signal is input when the temperature inside the drum chamber 32 is 39 ° C. or higher. Error message and stops the operation.

At this time, the power is not applied to the remaining components in the event of an abnormality in each of the operating members, in particular the cooling means 34, as well as the heating means 40, the temperature sensor 50 and the coffee beans temperature sensor 50B. To protect the stir-fryer.

On the other hand, the control means 80 is configured to accumulate and store the number of operations of the start switch 848, and to display the total number of times of use when the operation of the use display button 842A on the use display unit 882A, the electronic meter 90 stores and calculates the total cumulative amount of beans finally weighed, and displays the total amount of beans on the use display unit 882A when the use display button 842A is operated.

For example, a separate timer may be operated by a signal generated every time the start switch 848 is operated each time, and the number of operations of the start switch 848 may be accumulated and stored by the timer. In order to display the stored number of times as described above, the number of times of use may be displayed on the use status display part 882A using the use display button 842A. In addition, the electronic meter 90 accumulates and stores the weight of the coffee beans finally weighed so that when the user operates the use display button 842A, the total usage may be displayed on the use display unit 882A. It is.

At this time, the temperature sensor 50 to detect the temperature inside the drum chamber 32 is used to detect the room temperature.

Referring to the operation of the present invention configured as described above are as follows.

The support member 11 is installed on the front support plate 10, the rotation shaft 32D of the drum chamber 32 is coupled to one inner diameter of the support member 11, and is exposed to the outside of the viewing window 12C. On the other side of the supporting member 11, an elastic member 11C is installed on the other side of the viewing window 12C in close contact with the front support plate 10, and the second screw thread 11B formed in the outer diameter of the supporting member 11 is provided. A tightening nut 11D for pressing the elastic member 11C is fastened, and an adjustment knob 11E coupled to the outer cover 10C is attached to the first screw thread 11A formed at the inner diameter of the support member 11. In the fastened state, the rotating shaft 32D is supported by a bearing built into the support member 11 to be freely rotatable.

In this state, in order to clean the see-through window 12C or to maintain the drum chamber 32, etc., loosen the adjusting knob 11E coupled to the outer cover 10C and fastened to the other inner diameter of the support member 11, The outer cover 10C is separated from the cover member 10B.

When the tightening nut 11D is released from the second screw thread 11B formed at the outer diameter of the support member 11 in this state, the elastic force of the elastic member 11C that has been pressing the viewing window 12C is reduced, and then When the elastic member 11C is separated from the other end of the support member 11, the viewing window 12C may be separated from the front support plate 10. In this way, by loosening and tightening the adjusting knob 11E and the fastening nut 11D, the installation structure and disassembly / combining work of the front support plate 10 can be easily and quickly performed.

On the other hand, when the first main switch 820 is "on", the microcomputer 860 measures the voltage of the power applied, and applies the power to the voltage / temperature display unit 881 to display the incoming voltage The electronic meter 90 is initialized.

In such a state that the roaster is initialized, in order for the user to fry the raw beans, first, the measuring container 18 installed in the drawer type on the front support plate 10 is removed and placed on the electronic meter 90. When the measuring container 18 is placed on the electronic meter 90, the electronic meter 90 measures the net weight of the measuring container 18, and measures the weight of the measured measuring container 18 at the time / weight. Displayed on the display unit 882.

In this case, the microcomputer 860 displays an error message on the time / weight display unit 882 when the weight of the coffee beans weighed by the electronic meter 90 is set, for example, when the weight exceeds 1 kg. Will not. This is to prevent various components from being excessively operated when roasting the excess capacity as described above.

Subsequently, when the user presses the zero button 841, the microcomputer 860 resets the time / weight display unit 882. That is, when the user presses the zero button 841, the electronic meter 90 is reset.

In this state, the user puts the raw beans in the weighing container 18 and places them on the weighing container 90. When the electronic meter 90 is reset and the measuring container 18 containing the beans is lifted up, the electronic meter 90 results in measuring only the weight of the beans.

That is, since the empty weighing container 18 is placed and the full weighing machine 90 is reset, when the weighing container 18 containing the beans is placed, the electronic weighing machine 90 measures only the weight of the beans.

When the weight of the coffee beans is measured by the above process, the user opens the feeding cover 22D of the supply means 22 and inputs the raw coffee contained in the measuring container 18 to the feeding guide 22B.

Meanwhile, when the closing cover 22D is opened, the microcomputer 860 operates the first operating member 22G based on a signal detected by the opening / closing sensing member 22E.

When the input door 22F is lifted upward, and the coffee beans are fed into the feeding guide 22B while the first operating member 22G is opened, the coffee beans injected into the feeding guide 22B are It is supplied into the drum chamber 32 through the injection hole 22A formed in the rear support plate 20 along the photographic base plate 22C.

That is, when the input cover 22D is opened in order to supply the coffee beans metered by the electronic meter 90 to the drum chamber 32, the opening / closing sensing member 22E receives the open signal transmitted by detecting the opening. By operating the first operating member 22G to open the input hole 22A by the input door 22F, and then closing the input cover 22D again, the opening / closing detecting member 22E detects this. Receiving the closing signal sent out to operate the first operating member (22G) to close the closing hole (22A) of the input door (22F).

When the dispensing of coffee beans is completed, the user presses the display button 842. The display button 842 is used as a time / temperature button as well as the weight input button. As such, when the display button 842 is pressed, the weight of beans measured by the electronic meter 90 is input to the microcomputer 860, and the microcomputer receives the weight of the coffee beans from the electronic meter 90. 860 accumulates and stores the weight of the input beans, and in this state, when the user presses the use display button 842A to grasp the total usage of the beans, the microcomputer 860 stores the total weight of the beans. (Total usage amount) is displayed on the use status display portion 882A.

When the weight of the coffee beans is input in the above process, the user selects and inputs the size of the coffee beans into the size selection button 843. When the size of the beans is input, the microcomputer 860 turns on the power by applying power to the selected size selection lamp.

In this state, the microcomputer 860 receives the room temperature detected by the temperature sensor 50 as data for automatically setting the temperature and time required for roasting the beans together with data such as voltage and size of the beans. I use it.

Subsequently, when the size selection of the beans is completed, the microcomputer 860 checks whether the temperature or time required for the roasting of the beans is input from the temperature selection button 843 or the time selection button 846, and selects the temperature. When the temperature or time is input from the button 843 or the time selection button 846, the microcomputer 860 recognizes the manual progress mode. If the temperature or time is not input, the microcomputer 860 enters the automatic progress mode. Will be recognized. Therefore, the roaster according to the present embodiment can be switched to the automatic or manual mode without the user operating a separate switch.

In this state, the microcomputer 860 checks whether the user inputs the roasting degree of the coffee beans through the color selection button 844. If the user inputs the color, the microcomputer 860 receives the color of the coffee beans. , Among the lamps indicating the degree of roasting of the beans, turn on the lamp corresponding to "strong". In other words, the operation of the color selection button 844 does not affect the manual or automatic progress mode switching.

At this time, the automatic progress mode can be initially set. In other words, if the automatic progress mode is set to "weak" or "middle" and does not change randomly, it can proceed to the set mode. In the present embodiment, the degree of roasting is initially described based on a state set to "river".

On the other hand, after being recognized in the automatic progress mode, when the start switch 848 is "on", the microcomputer 860 drives the timer 890, the real-time input from the timer 890 receives the input data Calculates and displays the advancing step and the advancing time on the voltage / temperature display unit 881 and the time / weight display unit 882, respectively, and applies power to the first driving member 26 for driving the drum chamber 32. Allow forward rotation.

When the drum chamber 32 is rotated forward by the first drive member 26, the introduced beans are flown in the drum by the transfer wire 32C, and then the micom 860 is heated by the heating means 40. ) Is applied to the heating means 40 made of a halogen lamp is turned on to generate heat.

When power is applied to the heating means 40, the temperature inside the drum chamber 32 is raised to a one-step roasting temperature over about 6-8 minutes depending on the inlet voltage and room temperature, and senses the temperature being raised. The temperature sensor 50 transmits the detection signal to the microcomputer 860 in real time.

In this case, the microcomputer 860 is applied to the temperature inside the drum chamber 32 and the heating means 40 to the voltage / temperature display unit 881 and the time / weight display unit 882 of the display unit 880 From this point of time, the time of the timer 890 is controlled to display the roasting progress time.

As the roasting of the beans proceeds as described above, in the roasting process of the beans, the microcomputer 860 is heated to the heating means 40 such that the temperature in the drum chamber 32 detected by the temperature sensor 50 becomes 260-330 ° C. By controlling the amount of current applied to adjust the amount of heat, when the temperature detected by the coffee bean temperature sensor 50B reaches 230-235 ℃ turn off the heating means 40 and when the temperature falls below 230 ℃ heating means 40 again Turn on) to adjust the temperature. As described above, the smoke generated from the roasting of the beans, that is, the exhaust gas, is burned in multiple stages while passing through the small smoker 61, and then discharged to the outside through the communication 63.

That is, the smoke introduced into the small smoke 61 is first burned while passing through the first heating wire 61L provided between the lower insulating plate 61H and the insulating separator 61K, and again, the insulating separator 61K. And second combustion while passing through the second heating wire (61M) provided between the upper insulating plate and 61G is discharged to the outside through the communication (63). The length of the communication 63 is preferably about 40-50 cm, which is to facilitate the discharge of the exhaust gas.

On the other hand, look at the operation of the small smoke 61 according to another embodiment of the present invention as follows. As shown in FIG. 8B, the smoke introduced into the small combustion machine 61 through the discharge pipe 64 passes through the lower base 61 through the inlet 61-1A formed at the center of the lower base 61-2. -2) is introduced into the lower base 61-2 through a plurality of inlet holes 61-2A formed around the inlet hole 61-2A formed at the same time as it is introduced into the interior. At this time, since the space is formed between the bottom surface of the lower base (61-2) and the seating portion (61-1E) of the inner case (61-1C) by the annular gap holding end (61-2C), the lower base Smoke (emission gas) can flow in between the bottom of 61-2 and the mounting part 61-1E.

As such, the smoke introduced into the lower base 61-2 is discharged from the lower base 61-2 while being primarily burned by the lower heating wire 61-4 installed on the bottom surface of the insulating member 61-6. Deodorized by far infrared rays.

Subsequently, the primary combustion of the smoke by the lower heating wire 61-4 is carried out between the middle portions of the upper and lower bases 61-3 and 61-2, that is, between the upper and lower bosses 61-3B and 61-2B. It is introduced into the upper base (61-3) through a space formed between the edge of the insulating member (61-6) and the inner diameter of the upper, lower base (61-3, 61-2) installed in the.

Smoke introduced into the upper base 61-3 is discharged from the upper base 61-3 while secondary combustion is performed by the upper heating wire 61-5 installed on the upper surface of the insulating member 61-6. Far infrared rays deodorize the odor contained in the smoke. Therefore, since the smoke is burned in multiple stages while passing through the lower base 61-2 and the upper base 61-3, and the smell is deodorized, a plurality of discharge holes 61-3A formed in the upper base 61-3. Only heat can be discharged through the communication (63).

When this process is performed, the microcomputer 860 checks the temperature inside the drum chamber 32 detected by the temperature sensor 50, so that the temperature inside the drum chamber 32 is one-step roasting temperature 310-. When the temperature reaches 330 ° C., preferably 320 ° C., the amount of current applied to the heating means 40 is adjusted so that the inside of the drum chamber 32 is at the first stage roasting temperature for one stage roasting time (2-6 minutes). 4 minutes) and check if the initial roasting time has elapsed. At this time, the first stage roasting temperature is varied according to the voltage introduced or the size of the beans as described above. In this case, the microcomputer 860 may apply power to the fourth operating member 68A so that the damper 68 may halve the discharge pipe 64.

In addition, the microcomputer 860 of the control means 80 turns off the heating means 40 when the temperature of the beans detected by the coffee bean temperature sensor 50B reaches 230-235 ° C., and the temperature of the coffee beans is 230 When the temperature is lower than or equal to Celsius, the temperature in the drum chamber 32 is maintained to be appropriate for each gospel temperature while turning on the heating means 40.

When the temperature inside the drum chamber 32 is maintained at the first stage roasting temperature (310-330 ° C.) and the initial roasting time (5-6) has elapsed, the microcomputer 860 is a temperature inside the drum chamber 32. Check whether the second stage roasting temperature (295-315 ℃, preferably 305 ℃) subtracted 10-20 ℃ at the first stage roasting temperature, if the second stage roasting temperature, the amount of current applied to the heating means 40 By controlling the amount of heat generated by the control, the drum chamber 32 is maintained at the second stage roasting temperature for two stages of roasting time (2-6 minutes, preferably 4 minutes), and checks whether the two stages of roasting time have elapsed. do.

That is, when the temperature inside the drum chamber 32 is maintained at the first stage roasting temperature and the first stage roasting time has elapsed, the microcomputer 860 is heated such that the temperature inside the drum chamber 860 becomes the second stage roasting temperature. The amount of heat generated is controlled by controlling the amount of current applied to the means 40. At this time, the time required for changing from the first stage roasting temperature to the second stage roasting temperature takes approximately 25-35 seconds.

The shell separated from the beans roasted in this process is collected in the shell 14 installed on the front support plate 10 through the through hole 32B perforated in the drum chamber 32. At this time, since both side plates 35 of the drum cover member 30 are vertically formed, the shells discharged through the through holes 32B do not accumulate in the side plates 35.

When the temperature inside the drum chamber 32 is maintained at a two-step roasting temperature and the two-step roasting time has elapsed, the microcomputer 860 sets the temperature inside the drum chamber 32 at a two-step roasting temperature at 1-10 ° C. Change to subtractive three-step roast temperature (285-310 ° C., preferably 300 ° C.) to maintain for three-step roasting time.

At this time, the three-step roasting time is a time step selected by the user in the separation time from 1 minute to 5 minutes 30 seconds as described above, that is, if the user operated the nine-step button to select the color of the beans, three-step roasting Since the time is 5 minutes, the microcomputer 860 is to maintain the three-step roasting time for 5 minutes. In other words, the three-step roasting time is a time input by the user using the color selection button 844.

On the other hand, since the user can visually confirm the beans roasted through the see-through window 12C of the see-through means 12, the user checks the roasted state of the beans through the see-through window 12C and when left unattended. However, when an abnormality occurs in the roasted state, for example, when the beans are roasted in an undesired color, the stopper 849 may be used to emergency stop the stopper.

In addition, the components required for the progress during the roasting of the beans, for example, various operating members, various driving members, the temperature sensor 50, the temperature sensor 50B, the components such as heating means 40 When the abnormality occurs, the microcomputer 860 first displays an error message on the voltage / temperature display unit 881 or the time / weight display unit 882, and checks whether power is supplied to the heating unit 40. If power is not supplied to the heating means 40, all power is cut off. If power is supplied, only the power supplied to the heating means 40 is cut off, and power is supplied to the third operating member 34D to cool the cooling door 34C. ) Opens the air inlet hole (34A), and when the air inlet hole (34A) is opened, the heat generated in the drum chamber (32) by applying power to the blower fan (62) and the fourth operating member (68A). And exhaust gas, the air inlet hole 34A is opened and exhaust gas is exhausted. In the discharged state, the temperature sensor 50 checks the temperature inside the drum chamber 32, and if the temperature inside the checked drum chamber 32 is 45-55 ° C. or less, all power is cut off and the drum chamber 32 If the internal temperature is 45-55 ° C or more, the process returns to the step of checking the temperature inside the drum chamber 32 to check the internal temperature again.

This is to stop after cooling the inside of the drum chamber 32 in order to prevent such a risk, such as a fire may occur if all the power is cut off while the drum chamber 32 is heated.

In addition, the microcomputer 860 is configured to check whether there is an abnormality of each component before the roasting of the beans as described above, to display an error message when an abnormality occurs and not to operate in the next step.

On the other hand, when the temperature inside the drum chamber 32 is three-step roasting time to three-step roasting temperature has elapsed, the microcomputer 860 cuts off the power applied to the heating means 40, the respective cooling doors ( 34C applies power to the third operating member 34D to open the air inlet hole 34A and the inlet of the cooling blower 31, and at the same time, applies power to the cooling blower 31 to cool the blower 31. ) To supply external air to the drum chamber 32, to operate the blowing fan 62 of the gas discharge means 60 and to apply power to the fourth operating member (68A) to the damper (68). To open the rear discharge pipe (64).

At this time, a part of the shell is filtered in the strainer 69 installed at the rear of the discharge pipe 64, and the oil contained in the smoke, as well as various foreign matters are filtered out.

As described above, when each of the cooling doors 34C opens the air inlet hole 43A and the cooling blower 31 operates, the outside air is forced into the drum chamber 32 to quickly cool the beans. It will be done.

Subsequently, the microcomputer 860 turns on the cooling display lamp 885.

At this time, it is preferable to open the air inlet hole 34A about 5 seconds before the operation of the blower fan 62, which is performed when the air inlet hole 34A is not opened. It is operated to form a vacuum state in the drum chamber 32, thereby preventing the separated shell from entering the drum chamber 32 again.

In addition, when the cooling blower 31 and the blower fan 62 are operated as described above, the exhaust gas generated by the heat and roasting in the drum chamber 32 is forcibly discharged to the discharge pipe 64 and discharged. Exhaust gas is discharged after the odor and harmful components are removed and purified while passing through the ion generator 66 installed on one side of the blower fan 62, and then some shells and oils are finally removed from the strainer 69. will be. Ions generated from the ion generator 66 remove odor remaining in the drum chamber 32.

Subsequently, the power applied to the heating means 40 is cut off, and the microcomputer 860 is inside the drum chamber 32 in a state in which heat and exhaust gas are discharged to gradually decrease the temperature inside the drum chamber 32. The temperature of is maintained during the multistage aging stage.

That is, the aging machine is a primary aging unit for 1-3 minutes to maintain the temperature of the drum chamber 32 is lowered to 310-240 ℃, and maintained for 7-10 minutes at 260-40 ℃ when the primary aging machine has elapsed It is made of a secondary aging machine.

In other words, That is, when the power applied to the heating means 40 is cut off, the temperature inside the drum chamber 32 gradually decreases, and in this state, the roasted beans have a primary ripening machine. At this time, the microcomputer 860 cuts off only the power applied to the heating means 40.

Therefore, the microcomputer 860 checks whether the time when the temperature inside the drum chamber 32 falls to 310-240 ° C, that is, 1-3 minutes (preferably 2 minutes) has elapsed. Once passed (1-3 minutes have elapsed), the microcomputer 860 matures the roasted beans during the second ripening period. That is, when the primary aging machine has elapsed, the temperature inside the drum chamber 32 is further lowered. As such, the time for the temperature inside the drum chamber 32 to decrease to 260-40 ° C. (7-10 minutes, Preferably, 8 minutes) the microcomputer 86 is to leave the roasted beans to be matured in the secondary.

Therefore, the microcomputer 860 checks whether 7-10 minutes have elapsed while the temperature inside the drum chamber 32 falls to 260-40 ° C., and when the temperature of the drum chamber 32 is detected by the temperature sensor 50, 32) Check whether the internal temperature is discharge temperature (40-60 ° C., preferably 50 ° C.), and if discharge temperature is applied, power is supplied to the second operating member 24D so that the discharge door 24C is ground. Open the discharge hole (23).

Subsequently, the microcomputer 860 applies power to the second driving member 28 to operate the transfer conveyor 70, and discharges the first driving member 26 from 30 seconds to 1 minute 30 seconds. Rotating in the reverse direction during the roasting is completed so that the roasted coffee beans are discharged into the coffee cup holder 16 through the coffee bean discharge hole 23 by the transfer wire 32C.

At this time, after operating the second driving member 28 to operate the transport conveyor 70, and when the first driving member 26 is reversely rotated, beans roasted in the drum chamber 32 is By the spiral feed wire 32C fixedly installed on the inner circumferential surface of the drum chamber 32, it moves to the rear side, that is, to the bean discharge hole 23 side. This is because the transfer wire 32C is formed in a helical shape, when the drum chamber 32 is rotated forward, the beans move forward, and when rotated reversely, it moves backward.

As such, when the bean discharge hole 23 is opened and the transfer conveyor 70 is operated, and the drum chamber 32 is reversely rotated, the beans which have been roasted in the drum chamber 32 are drum chambers. It moves to the rear side in the 32 and is discharged to the bean tray 16 installed in the drawer type on the front support plate 10 through the bean discharge hole 23.

At this time, the coffee beans discharged to the coffee bean cup 16 are accumulated only in a part, which can be solved by operating the transfer conveyor 70. That is, since the transfer conveyor 70 disperses the coffee beans that are discharged to the coffee cups 16 and accumulated in only one place, the coffee beans to be discharged will be evenly contained inside the coffee cups 16.

On the other hand, the microcomputer 860 to which the first driving member 26 is supplied with power to reverse rotation checks whether the discharge time (30 to 1 minute 30 seconds) has elapsed, and when the discharge time has elapsed, the buzzer The 884 is operated 2-3 times, the stir-off lamp 886 is turned on, and each driving and operating source, that is, the first and second driving members 26 and 28, the second operating member 24D, and the third The roasting of the beans is completed by cutting off the power applied to the actuating member 34D and the fourth actuating member 69A.

As described above, since the roasting process, the cooling process, and the discharge process of the beans are automatically proceeded and the roasted beans are discharged to the bean tray 16, the user inputs the weight and size of the beans and selects colors. After inputting to the left and the stir fry machine, the subsequent operation is that the microcomputer 860 to automatically roast the beans by calculating a variety of data, the roasted beans are collected and used from the coffee beans receiving 16 It is just to clean the shell 14 for the next operation.

On the other hand, when the start switch 848 to continually roast the beans in the state of complete roasting of the beans is completed, the microcomputer 860 is the temperature in the drum chamber 32 detected by the temperature sensor 50 On the basis of this, the operation is performed or stopped. That is, when the temperature inside the drum chamber 32 detected by the temperature sensor 50 is 39 ° C. or higher, the microcomputer 860 does not allow the user to proceed with the next process even when the user operates the start switch 848. Will be. As such, it is possible to prevent excessive use of the roaster by operating only the state in which the roaster is cooled to a certain temperature, thereby reducing the failure rate of each part.

Such a fryer can easily grasp the total number of uses (total amount of roasted beans) as well as the final number of times by the following process.

That is, when the user operates the start switch 848, the microcomputer 860 of the control means 80 calculates and stores the number of operations. At this time, the microcomputer 860 preferably operates the start switch 848 to store the number of operations after the next process. When the user operates the use display button 842A in this state, the microcomputer 860 displays the total number of times of use of the stored roaster on the use display unit 882A. Therefore, the user can more easily manage the stator, such as to easily grasp the use of the stator, and to easily identify the period of replacement of the various parts.

In addition, the microcomputer 860 of the control means 80 stores, calculates and stores the total accumulation of the beans finally measured by the electronic meter 90. At this time, the microcomputer 860 is based on the weight signal input by the electronic meter 90 to the microcomputer 860. In this state, when the user operates the use display button 842A, the microcomputer 860 displays the total amount of beans stored in the use display unit 882A. It will be managed.
