Description

Coffee bean roasting device

This model relates to a coffee bean processing equipment, in particular to a coffee bean roasting device.

Referring to FIG. 1, there is an existing coffee roasting barrel 1, which includes a barrel body 11 that defines a container space 110 suitable for accommodating coffee beans to be processed, and a barrel body 11 connected to the barrel body 11 and used to drive the barrel body 11 The motor 12 rotates with a rotating shaft 121 extending laterally, and a heating source 13 disposed radially below the barrel 11. When roasting coffee beans to be processed, the coffee beans are placed in the containing space 110, and then the motor 12 and the heating source 13 are turned on. While the motor 12 drives the barrel 11 to rotate, the containing space 110 The coffee beans in the container will be stirred, and the heating source 13 will provide heat to the containing space 110 to achieve the purpose of roasting the coffee beans.

However, regardless of whether the heating source 13 uses electric energy, direct fuel fire, or other mechanisms, since the heating source 13 directly heats the barrel body 11, the barrel body 11 itself and the containing space 110 will inevitably be caused by conduction and convection. There is a difference in temperature. In this case, it is not only difficult to accurately control the temperature parameters of the actual coffee beans, but also although the coffee beans in the containing space 110 will be stirred due to the rotation of the barrel 11, they will be directly exposed to relatively high temperature. In the case of the barrel body 11, it is quite easy to cause burnt black due to excessively high temperature, which greatly affects the baking uniformity, and therefore the taste and quality are difficult to effectively improve.

Therefore, the purpose of the present invention is to provide a roasting device that can ensure evenness and precision of roasting coffee beans.

Therefore, the roasting device for coffee beans of the present invention includes a processing unit, a pneumatic unit connected to the processing unit, and a control unit connected to the processing unit and the pneumatic unit.

The processing unit includes a main body defining an inner space, a partition arranged in the inner space and dividing the inner space into a baking area and an installation area, and a heater arranged in the installation area. The partition has a plurality of vent holes penetrating between the roasting area and the installation area and having a diameter smaller than that of the coffee beans.

The pneumatic unit includes a first pipeline connected to the installation area, and a blower connected to an end of the first pipeline opposite to the installation area, and the air flow provided by the blower enters the installation area from the first pipeline Passing through the heater and passing through the vent holes, a hot airflow suitable for roasting the coffee beans is formed in the roasting area.

The control unit includes a temperature controller connected to the heater and a regulator connected to the blower.

The effect of the present invention is that when the air flow provided by the blower enters the roasting area through the partition, the coffee beans in the roasting area will be blown up one after another and hang in the air. With the circulation of the coffee beans falling in the air due to their own weight, the air The uniform stirring effect, and the use of the hot airflow formed by the heater for baking can also form a uniform temperature environment in the baking zone, thereby ensuring the uniformity of baking, and at the same time cooperate with the precise control of the control unit The adjustment of temperature and air volume can achieve more precise baking.

2 and 3, it is an embodiment of a new type of coffee bean roasting device. This embodiment includes a processing unit 2, a pneumatic unit 3 connected to the processing unit 2, and a pneumatic unit 3 connected to the processing unit 2. The feeding unit 4, a terminal unit 5 connected to the pneumatic unit 3 and arranged downstream of the processing unit 2, and an information connection to the processing unit 2 and the control unit 9 of the pneumatic unit 3. It should be noted that in this embodiment, all the components are arranged on a dedicated bracket as shown in FIG. 2 to form an integrated machine, but the shape of the dedicated bracket can be easily completed according to requirements. It is also not the main technical feature of this case, so I will not repeat the relevant details in the following.

The processing unit 2 includes a main body 21 that defines an inner space 200, a partition 22 arranged in the inner space 200 and dividing the inner space 200 into a baking area 201 and an installation area 202, and a partition 22 arranged in the inner space 200. The heater 23 of the installation area 202, a miscellaneous material bucket 24 spaced apart from the main body 21 and defining a collection space 240 with an exhaust port 249, and a miscellaneous material barrel 24 arranged in the installation area 202 and located downstream of the heater 23 Ejector 25 to concentrate the airflow. The partition 22 has a plurality of vent holes penetrating between the roasting area 201 and the mounting area 202 and having a diameter smaller than that of the coffee beans (due to the relationship between the viewing angle and the small size, it is not shown in the figure). Wherein, the roasting area 201 is located above the installation area 202 and is suitable for accommodating a certain amount of green coffee beans for roasting.

The feeding unit 4 includes a feeding pipe 41 connected to the baking zone 201 and a hopper 42 connected to the feeding pipe 41. The green coffee beans to be processed can be guided by the hopper 42 and enter the roasting area 201 through the feed pipe 41.

The end unit 5 is spaced from the processing unit 2 and includes a net that defines a cooling space 500 and has a bottom with a plurality of wind holes (not shown in the figure due to the relationship between the viewing angle and the small size) The collecting bucket 51 of the plate 511 and a supporting seat 52 for the collecting bucket 51 to be detachably placed and having an air inlet 520.

The pneumatic unit 3 includes a first pipe 31 connected to the installation area 202, a blower 32 connected to an end of the first pipe 31 opposite to the installation area 202, and a blower 32 connected to the baking area 201 and the cooling area. A second pipeline 33 between the spaces 500, a third pipeline 34 connected between the first pipeline 31 and the air inlet 520, and a third pipeline 34 arranged in the second pipeline 33 for opening The coffee beans in the roasting zone 201 enter the cooling space 500 through the second pipe 33 and the collecting valve 35, which is arranged in the third pipe 34 and is used to guide the airflow through the wind when it is opened. A vent valve 36 with a hole entering the cooling space 500, a de-trash pipeline 37 connected between the baking area 201 and the collection space 240, and a de-trash pipeline 37 arranged in the de-trash pipeline 37 and used for opening The impurities in the baking zone 201 are guided to the impurity removal valve 38 of the collection space 240 through the impurity removal pipeline 37. The first pipeline 31, the second pipeline 33, the third pipeline 34, and the impurity removal pipeline 37 of the pneumatic unit 3, specifically, the processing unit 2 and the terminal unit 5 are completely connected, and A complete air flow path system is formed so that the air flow generated by the operation of the blower 32 can be changed by controlling the opening or closing of the collecting valve 35, the vent valve 36, and the trash removal valve 38 to change the flow path of the air flow. Meet the process requirements of roasting coffee beans.

The control unit 9 includes a temperature controller 91 connected to the heater 23, a regulator 92 connected to the blower 32, a collection switch 93 for controlling the collection valve 35, and a collection switch 93 for controlling the ventilation. The vent switch 94 of the valve 36 and a trash removal switch 95 for controlling the trash removal valve 38. Among them, in this embodiment, the control unit 9 is preferably designed as a touch operation panel and a plurality of button switches, but it is not limited to this. Specifically, the temperature controller 91 uses a variable resistance adjustment mechanism, or presets a number of specific temperature digital adjustments, and the adjuster 92 mainly adjusts the air volume of the blower 32. In addition, the opening and closing of the collecting switch 93, the vent switch 94, and the cleaning switch 95 can preferably be designed with a pre-designed control program to design a predetermined switching time and sequence to match the baking time, Temperature and automatic operation, in order to achieve the needs of fully automated baking.

Referring to FIG. 4 and in conjunction with FIG. 2, when roasting is performed using this embodiment, the green coffee beans are first passed through the hopper 42 placed in the feeding unit 4, and the green coffee beans enter the roasting area 201 through the feeding tube 41. Then, since the installation area 202 is between the baking area 201 and the blower 32, and the baking area 201 is located at a higher position than the installation area 202, when the blower 32 and the heater 23 are both turned on, And make the vent switch 94 close the vent valve 36, the air flow provided by the blower 32 will first enter the installation area 202 from the first pipeline 31, and form a hot air flow by passing through the heater 23, and then pass through the jet The device 25 is adjusted to the required airflow pattern. When the hot airflow enters the roasting zone 201 through the vents of the partition 22, the lifting force of the airflow will blow the green coffee beans upward, and a uniform temperature environment will also be formed in the roasting zone 201. Since the green coffee beans have a certain weight, they will fall down due to gravity after being lifted to a certain height by the airflow. Therefore, this circulation mechanism can be used to properly adjust the air volume of the blower 32 in conjunction with the regulator 92. When a good convective circulation is formed, a uniform stirring effect is achieved. In addition, since the present embodiment roasts coffee beans in a uniform temperature environment in the roasting zone 201, evenly stirring with hot air blowing can achieve a multiplier effect, so a particularly excellent roasting uniformity can be achieved.

In particular, because green coffee beans of different varieties and origins have different roasting temperature and time requirements, the operation requirements of light roasting, medium roasting, and even deep roasting can be adjusted by the temperature controller 91 The required temperature, and preset the required baking time.

Referring to Figure 5, in the process of roasting coffee beans, impurities such as the silver film on the surface of the coffee beans and the ground powder of abnormal beans are lighter than the whole coffee beans, so they will be forced by the airflow blowing from the bottom to the top. Separate from the coffee beans and move relatively upward. At this time, since part of the trash removal pipeline 37 extends upward from the roasting area 201, as long as the roasting of coffee beans is started, the trash removal switch 95 is synchronously controlled to open the trash removal valve 38, and at the same time, the aggregate The switch 93 closes the collecting valve 35, and impurities with low density and continuously blown upward by the airflow will be transported from the roasting zone 201 to the collection space 240 of the miscellaneous material bucket 24 through the de-trash pipeline 37. In addition, considering the possibility that the airflow needs to be directly discharged from the collection space 240, the collection space 240 is preferably provided with a filter 247 for filtering the impurities, and located between the filter 247 and the row Activated carbon 248 between the outlets 249 and used to filter the gas. When the gas containing impurities enters the collection space 240, the filter 247 can filter the impurities with relatively large particle size first, and the activated carbon 248 can absorb odors, such as carbon dioxide gas, and the relatively small particle size. Dust impurities ensure that the gas discharged from the discharge port 249 will not cause adverse effects on the surrounding environment.

6 and 7, when the coffee beans are roasted in the roasting zone 201, only control the collecting switch 93 to open the collecting valve 35, and at the same time make the trash removal switch 95 close the trash removal valve 38, roasting The finished coffee beans can enter the cooling space 500 of the collecting bucket 51 through the second pipe 33 by the blowing force of the airflow. At this time, because the coffee beans have just been roasted and the temperature is still high, the vent valve 36 is opened by the vent switch 94, and the air flow generated by the blower 32 will pass through the second pipe 34, and then by the carrier 52. The air inlet 520 enters the cooling space 500 through the air holes, so as to cool the roasted coffee beans by blowing the air flow not heated by the heater 23 directly. It should be particularly noted that the air flow used to cool the coffee beans at this stage also needs to be properly adjusted by the regulator 92 to adjust the air volume of the blower 32. In addition to grasping an appropriate and efficient cooling time, it also avoids excessively strong cooling time. The blowing force loses the aroma of the coffee beans.

Finally, after the cooling is completed, the roasting process of the coffee beans is completed. As long as the vent valve 36 is closed, and the collecting bucket 51 is directly removed from the supporting seat 52, the roasted coffee beans can be obtained. Subsequently, as long as the collecting bucket 51 is re-placed on the supporting base 52, another round of coffee bean roasting process can be restarted. Of course, the heating stage as shown in FIG. 4, the stripping and de-impurity stage as shown in FIG. 5, and even the discharging and cooling stage as shown in FIG. 6 and FIG. With proper settings of the control unit 9, each individual stage can be automatically switched, and the use is not limited to the execution of a complete process.

To sum up, in this embodiment of the coffee bean roasting device of the present invention, when the airflow provided by the blower 32 enters the roasting zone 201, the coffee beans in the roasting zone 201 will be blown up and suspended. After the beans are suspended in the air, the cycle of falling due to their own weight produces a uniform stirring effect. At the same time, by the hot air flow formed by the heater 23, a uniform temperature environment can be formed in the roasting zone 201 to roast the coffee beans to ensure roasting At the same time, with the multi-stage precise temperature control and air volume adjustment of the control unit 9 and other detailed parameters adjustment, in addition to achieving the automation of the complete baking process of heating, removing impurities, stripping, collecting, and cooling, it can also achieve The precision of baking. Therefore, it can indeed achieve the purpose of cost-new type.

However, the above are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
