Description

Grinding system

The present invention relates to a grinding system and a grinding method, and more particularly to a grinding system and a grinding method capable of setting the rotational speed of a driving module.

Good coffee, in addition to high-quality coffee beans and baking, the appropriate extraction of sour, sweet, bitter, salty and other flavors of coffee, in order to get a cup of sweet and sour, bright, sweet and mellow coffee. The extraction process determines the change in the taste of the coffee. The common control factors are the temperature, pressure and extraction time during extraction, as well as the amount of coffee powder, the thickness of the coffee powder, and so on.

At present, the world coffee trend has entered the so-called "third wave coffee", emphasizing the use of light and medium baking to interpret the bright and lively coffee with strong floral aroma characteristics, while the brewing of shallow coffee is testing. The ability of the barista to regulate various brewing parameters, however, each brewing parameter has an adjustment limit, and the adjustment of each parameter often affects the interaction. It is the pursuit of each professional barista that can accurately control the brewing flavor change. The goal.

Recent studies have found that the particle size distribution of coffee powder after grinding of coffee beans, including the uniformity of the particles and the amount of fine powder produced during grinding, has a critical impact on the flavor change during coffee extraction. Coffee beans are ground to a powder using a coffee grinder. However, different grinders have different cutter types and different cutter sizes with different power motors. These factors determine the coffee beans after grinding. Particle size distribution.

However, in the same grinder, the cutter pattern, the cutter size and the motor are fixed, and only the grinding thickness can be changed. This is impossible for the particle size distribution and fine powder amount under the same grinding scale. The change has changed so that the change of coffee extraction flavor has not been adjusted more effectively. It is difficult to cope with the finer flavor requirements of the third wave of light roasted coffee, and it is necessary to obtain a larger flavor change unless it is replaced by one. Taiwanese grinders, so many professional coffee shops, there are often many different types of grinders.

The embodiments of the polishing system and the polishing method according to the present invention will be described below with reference to the related drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals.

Please refer to FIG. 1 to FIG. 4 , which are schematic diagrams, structural drawings, particle size curves and flavor curves of the first embodiment of the polishing system of the present invention. As shown, the polishing system 1 includes a polishing device 10 and a control device 11. The polishing apparatus 10 includes a device body 100, a receiving module 101, a driving module 103, and a cutting module 102. The accommodating module 101 is disposed at one end of the device body 100. The accommodating module 101 is recessed inwardly to form a receiving slot 1010 for receiving a plurality of objects 2, and the other side of the accommodating module 101 has an opening 1011. The cutting module 102 is disposed in the device body 100, and one end of the cutting module 102 is connected to the opening 1011. The driving module 103 is disposed in the device body 100. The driving module 103 has a rotating component 1030 at one end and is connected to the other end of the cutting module 102. The control device 11 is electrically connected to the driving module 103. When the control device 11 receives the activation signal 110A and the preset rotation signal 113, the control device 11 adjusts the preset required for the operation of the driving module 103 according to the preset startup time. The operating current 111 is supplied to the driving module 103 to drive the driving module 103 to rotate, so that the driving module 103 drives the cutting module 102 to rotate and rotate the plurality of objects 2 by the rotating component 1030. The control device 11 controls the driving module 103 to gradually accelerate from the starting speed to the preset operating speed according to the preset speed signal 113 in the preset acceleration time.

Specifically, the polishing system 1 of the present invention includes a polishing device 10 and a control device 11. The polishing device 10 can be a polishing device. The polishing device 10 includes a device body 100, a receiving module 101, a driving module 103, and a cutting module 102. The device body 100 can be a housing structure. The receiving module 101 is disposed at one end of the device body 100. The receiving module 101 is recessed inwardly to form a receiving slot 1010 for receiving a plurality of objects 2, such as coffee beans. The device body 100 is further provided with a driving module 103 (such as a DC motor, an AC motor, a stepping motor or a servo motor), and the rotating component 1020 at one end of the driving module 103 is disposed on the other surface of the accommodating module 101. The cutting module 102 is disposed in the receiving slot 1010 of the receiving module 101 and is connected to one end of the rotating component 1020. The cutting module 102 can be a grinding blade such as a flat knife, a cone cutter or a ghost tooth. The control device 11 is electrically connected to the driving module 103.

When the polishing system 1 is in operation, the control device 11 first receives the start signal 110A and the preset speed signal 113, and then the control device 11 will operate the drive module 103 for a preset start time (eg, 2 seconds). The operating current 111 (such as the rated current) is increased to a preset starting current 112 (such as 1.5 times or more of the rated current), and a preset starting current 112 is provided to the driving module 103 to drive the driving module 103 to rotate. Then, since the plurality of objects 2 in the receiving slot 1010 are dropped into the cutting module 102 through the opening 1011, the driving module 103 can be driven by the rotating component 1030 (such as the driving shaft) when the driving module 103 rotates. The cutting module 102 rotates to grind a plurality of objects 2. Moreover, the control device 11 also controls the driving module 103 to gradually accelerate from the starting speed (the just running speed) to the preset operating speed (such as 500) according to the preset speed signal 113 and in the preset acceleration time (for example, 3 seconds). ~2000 rpm, determined according to the speed value corresponding to the preset speed signal 113 set by the user).

Since the conventional grinder does not have the control device 11, the following problems exist for a long time: the grinder motor (such as the drive module 103) is started differently from the general light load motor, and the grinding chamber (such as the cutting die) is started when the grinder is started. Group 102) is filled with coffee beans, and the cutter head is filled with coffee granules that have not been ground last time. Especially when grinding espresso coffee, it needs to be ground into very fine coffee powder. The distance between the cutters is very small, plus the cutter head. The coffee granules filled with the card form a brake-like state. When the power is turned on, the motor needs to overcome the great friction force to rotate, causing the motor starting current to be abnormally increased, and it is easy to jump due to overcurrent operation, and currently The common professional grinder in the city, whether it is store operation or household type, is limited by the use occasion, the volume can not be too large, but in order to allow the grinder to have a large enough starting torque to start and run the grinding machine Beans, usually equipped with 0.5 HP to 1.2 HP or higher power motors, plus the coffee grinder's general operation mode, will continue to switch on and off in a short time, that is, multiple high power in a short time Start-up operation, after a period of time the opportunity grinding hot, heat expansion and contraction pitch cutter affected, resulting in uneven polishing accuracy. Therefore, the traditional coffee grinder mostly drives the grinder cutter directly by the motor, or the motor drives the grinder cutter disc through the speed reduction mechanism, and the rotation speed is additionally set or controlled.

Accordingly, the polishing system 1 of the present invention can realize the grinding function by changing the rotation speed of the driving module 103 under the same polishing machine table by the above-mentioned structural design. Moreover, when the drive module 103 is operated at different rotational speeds, the obtained coffee powder particle size will not only be different (as shown in Fig. 3, c1 is 1500 rpm, c2 is 1000 rpm, c3 is 500 rpm), and after grinding The coffee powder is extracted into a coffee beverage, and its flavor will be different (as shown in Fig. 4, d1 is aroma, d2 is acidity, d3 is sweetness, d4 is bitterness, d5 is salty, d6 is alcohol thickness, d7 is Return to rhyme).

Further, when the control device 11 receives the activation signal 110A, and the control device 11 determines that the driving module 103 is in the stop operation state, the control device 11 drives the driving module 103 to perform a plurality of inching operations during the preset driving time. When the control device 11 determines that the preset driving time is over, the control device 11 increases the preset operating current 111 of the driving module 103 to the preset starting current 112 at a preset starting time, and drives the driving module 103 to rotate.

That is to say, when the polishing apparatus 10 is started, the storage tray 1010 and the cutter head of the cutting module 102 are filled with broken beans, and the state of high frictional resistance is exhibited. If the continuous operation is started, the motor cannot be overcome at one time, and the lock is blocked. Dead state, causing overcurrent protection and tripping. Therefore, after the control device 11 receives the activation signal 110A, if the control device 11 determines that the driving module 103 is in the stop operation state, the control device 11 can be in the preset driving time before starting the driving module 103 for normal operation (eg, 2 seconds) driving the drive module 103 to perform multiple inching operations (such as 0.3 second interval), that is, the driving module 103 performs instantaneous rotation at intervals of 0.1 second, so that the high friction resistance can be overcome and the motor can be smoothly started (drive module) 103).

Please refer to FIG. 5, which is a schematic view of a second embodiment of the polishing system of the present invention. Please also refer to Figures 1 to 4 together. As shown in the figure, the polishing system in this embodiment is similar to the operation of the same components described in the polishing system of the first embodiment described above, and therefore will not be described herein. However, it is worth mentioning that in the embodiment, the control device 11 includes an input module 11A, a processing module 11B, and a storage module 11C. The input module 11A can receive a plurality of touches to generate the start signal 110A and the preset speed signal 113; the processing module 11B is electrically connected to the input module 11A, and receives the start signal 110A and the preset speed signal 113; the storage module The 11C is electrically connected to the processing module 11B to store the preset speed signal 113. When the processing module 11B receives the start signal 110A and the preset speed signal 113, the processing module 11B increases the preset operating current 111 required to operate the driving module 103 to the preset starting current according to the preset starting time. 112, in order to drive the driving module 103 to rotate, and the driving module 103 drives the cutting module 102 to rotate a plurality of objects 2 by rotating the component 1030, and the processing module 11B accelerates according to the preset speed signal 113. In the time, the control driving module 103 is gradually accelerated from the starting speed to the preset operating speed.

That is to say, the control device 11 of the present invention further includes an input module 11A, a storage module 11B, and a processing module 11C. The input module 11A can be a physical button or a touch panel with virtual buttons. After the input module 11A sets the rotational speed of the drive module 103 via the user touch input, the input module 11A generates a preset rotational speed signal 113 accordingly. Then, when the user wants to start the polishing device 10 by touching the input module 11A, the input module 11A generates the activation signal 110A. Then, the processing module 11B increases the preset operating current 111 required for the operation of the driving module 103 to the preset starting current 112 according to the startup signal 110A and the preset rotation signal 113, and presets During the acceleration time, the control driving module 103 is gradually accelerated from the starting speed to the preset operating speed set by the user.

Please refer to Fig. 6, which is a schematic view of a third embodiment of the polishing system of the present invention. Please also refer to Figures 1 to 5. As shown in the figure, the polishing system in this embodiment is similar to the operation of the same components described in the polishing system of the first embodiment described above, and therefore will not be described herein. However, it is worth mentioning that, in this embodiment, when the control device 11 receives and drives the driving module 103 to stop according to the stop signal 114 and the control device 11 receives another activation signal 110B, the control device 11 detects the driving mode. The current rotational speed of the group 103 is accordingly provided to provide an accelerated starting current 115 to the drive module 103 to drive the drive module 103 to continue from the current rotational speed to the predetermined operational rotational speed.

For example, since the operation of the polishing apparatus 10 does not necessarily start from a standstill every time, that is, after the user stops the operation of the polishing apparatus 10, the user restarts the grinding apparatus 10 again before the driving module 103 is completely stopped. Operation, therefore, the current speed of the drive module 103 is tracked by the control device 11, and the starting current is supplied with the current speed in conjunction with the acceleration to avoid overcurrent heating. Therefore, after the control device 11 receives and drives the driving module 103 to stop according to the stop signal 114, when the control device 11 receives another activation signal 110B, the control device 11 can detect the current rotation speed of the driving module 103 (such as 200). Rpm), and according to the current speed, an acceleration starting current 115 is provided to the driving module 103 to drive the driving module 103 to accelerate from the current speed to a preset operating speed (a speed value set by the user, such as 500 rpm).

Please refer to Fig. 7, which is a schematic view of a fourth embodiment of the polishing system of the present invention. Please also refer to Figure 1 to Figure 6. As shown in the figure, the polishing system in this embodiment is similar to the operation of the same components described in the polishing systems of the above embodiments, and thus will not be described herein. However, it is worth mentioning that, in this embodiment, when the control device 11 determines that the preset startup time is over, and the driving module 103 is operated by the preset operating current 111 to reach the preset operating speed, the control device 11 reduces the driving. The preset operating current 111 of the module 103 is preset to a low operating current 116.

Specifically, after the smooth start of the polishing apparatus 10 of the present invention, in order to avoid a continuous high current, the temperature of the motor is increased, and when the set speed is maintained and the inertial force is assisted, the running current is moderately reduced, and the motor can be prevented from rising. . That is, when the control device 11 determines that the preset startup time is over, and the driving module 103 is operated by the preset operating current 111, and the preset operating speed has reached the preset operating speed, the control device 11 can lower the driving module 103. The preset operating current 111 is preset to a low operating current 116 (eg, 85% motor rated current operation) to prevent the operating temperature of the motor (drive module 103) from being too high.

Please refer to FIG. 8 , which is a schematic diagram of a fifth embodiment of the polishing system of the present invention. Please also refer to Figures 1 to 7. As shown in the figure, the polishing system in this embodiment is similar to the operation of the same components described in the polishing systems of the above embodiments, and thus will not be described herein. However, it is worth mentioning that, in this embodiment, when the driving module 103 operates by the preset operating current 111 and the control device 11 detects that the current rotational speed of the driving module 103 is lower than the preset operating speed, the control device 11 is to increase the preset operating current 111 of the driving module 103 to the acceleration rotating current 117 to drive the current rotational speed of the driving module 103 to a preset operating speed.

Specifically, since the number of objects 2 that the user has poured into the storage tub 1010 is not the same every time, if the load is increased and the rotation speed is delayed, the control device 11 can increase the current to compensate the torque. That is, when the driving module 103 is operated by the preset operating current 111 (eg, 500 rpm), the control device 11 detects that the current rotational speed of the driving module 103 (eg, 450 rpm) is lower than the preset operating speed, and the control device 11 is to increase the preset operating current 111 of the driving module 103 to accelerate the rotating current 117 (such as increasing the rated current of the motor to 120% of the motor rated current) to drive the current speed of the driving module 103 to a preset operation. Rotating speed.
