Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to coffee beans manufacturing apparatus according to an embodiment of the present invention.

1 is a block diagram showing a coffee beans manufacturing apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the coffee bean manufacturing apparatus 100 according to an embodiment of the present invention includes a water supply unit 120, a heater tank 128 with a heater, a mixing unit valve 130, and an extraction unit valve 132. ), An additional raw material supply unit 134, coffee beans supply unit 139, grinding unit 141, coffee liquid extraction unit 150 and mixing unit 153. Here, the water supply unit 120 includes a flow meter 122, a vibration pump 124 and a relief valve 126. And coffee beans manufacturing apparatus 100 according to an embodiment of the present invention includes a control unit (see 160 of FIG. 5) for controlling the grinding unit 141 and the coffee liquid extraction unit 132.

Hereinafter, each configuration of the coffee bean manufacturing apparatus 100 will be described in more detail.

The water supply unit 120 supplies the water supplied from the water source to the heater tank 128. Here, the water source may be a water supply and / or a bucket. Water supplied from the water source flows through the flow meter 122 and reaches the vibration pump 124. The flow meter 122 measures the amount of water supplied from the water source and transmits the measured value to the controller 160.

The vibration pump 124 pressurizes the supplied water to make high pressure (for example, 10 bar to 15 bar) in the heater tank 128. The high pressure of the water using the vibration pump 124 as described above is for easily extracting the coffee liquid from the coffee liquid extraction unit 150 later.

The relief valve 126 serves to keep the pressure in the heater tank 128 safely when the valve is opened when the pressure in the heater tank 128 is higher than the reference pressure (for example, 15 bar).

When the coffee beans are selected by the user, the water supply unit 120 operates by a signal from the controller 160 to pressurize the water supplied from the water source to form high pressure water and supply the same to the heater tank 128. .

The heater inside the heater tank 128 heats the high pressure water supplied from the water supply unit 120 until it reaches a set temperature (eg, 98 ° C.). Since the heater inside the heater tank 128 heats the water supplied from the water supply unit 120 in advance, when the coffee beans are selected by the user, the heater tank 128 can stably and quickly supply hot water. Since a temperature measuring sensor (not shown) is provided inside the heater tank 128, when the water inside the heater tank 128 becomes below a predetermined temperature, the controller 160 controls the heater inside the heater tank 128. To keep the water above a certain temperature at all times. High temperature and high pressure water from the heater tank 128 is introduced into the mixing unit 153 and the coffee liquid extraction unit 150 through the mixing unit valve 130 and the extraction unit valve 132.

The mixing part valve 130 and the extraction part valve 132 allow the high temperature and high pressure water from the heater tank 128 to be stably supplied to the mixing part 153 and the coffee liquid extraction part 150. That is, since the water from the heater tank 128 is very high in pressure and high in temperature, the mixing part valve 130 and the extraction part valve 132 are hot and high pressure water mixing part 153 and the coffee liquid extracting part ( 150) by controlling the amount of the inflow to ensure that the mixing of the additional raw materials and the extraction of the coffee solution can be made stably.

The additional raw material supply unit 134 stores additional raw materials additionally added to the coffee beans, such as sugar, prim, and chocolate, and supplies them to the mixing unit 153 by a signal from the controller 160. The additional raw material supply unit 134 supplies sugar and / or prim to the mixing unit 153 by a predetermined amount while operating for a predetermined time by a signal from the control unit 160. The additional raw material supply unit 134 may be provided corresponding to the type of additional raw material provided in the coffee bean manufacturing apparatus 100. For example, when the additional raw materials provided in the coffee bean manufacturing apparatus 100 are sugar, prim and chocolate, three additional raw material supply units 134 may be provided in the coffee bean manufacturing apparatus 100.

The detailed configuration of the additional raw material supply unit 134 will be described in more detail with reference to FIG. 3.

The coffee bean supply unit 139 stores the coffee beans and serves to supply the coffee beans to the grinder 141 according to a signal from the controller 160. The coffee beans supply unit 139 stores the coffee beans that are not ground, and the coffee beans are ground by the grinding unit 141 after the user selects the coffee beans and is supplied to the coffee liquid extracting unit 150. Therefore, the coffee bean manufacturing apparatus 100 according to the present embodiment may provide a coffee beans having excellent taste and aroma since the coffee beans are immediately ground to prepare coffee beans. The configuration of the coffee bean supply unit 139 may be the same as that of the additional raw material supply unit 134.

The mixing unit 153 mixes the high temperature and high pressure water introduced through the mixing unit valve 130 with the additional raw material supplied from the additional raw material supply unit 134. An impeller (not shown) is provided inside the mixing unit 153, so that when the additive and water are supplied, the impeller operates to mix the water and the additive. The mixed water and additives are supplied to a container such as a cup and mixed with the coffee extract.

In order to easily mix the additional raw material and the water, the controller 160 first supplies water to the inside of the mixing unit 153 and supplies the additional raw material in a state of stirring by an impeller. In this way, the water is first supplied from the inside of the mixing unit 153, and then the additional raw material is supplied later, so that the mixing of the additional raw material and water is performed well, and the residue of the additional raw material can be prevented from remaining in the mixing unit 153 and the like. have.

The grinding unit 141 grinds the coffee beans supplied from the coffee bean supply unit 139 to form coffee powder, and then supplies them to the coffee liquid extracting unit 150. The grinding unit 141 is operated by the signal of the control unit 160 and the input amount of the coffee powder supplied to the coffee liquid extraction unit 150 is determined according to the operation time. A detailed configuration of the grinding unit 141 will be described in more detail with reference to FIGS. 2A and 2B below.

The coffee liquid extracting unit 150 extracts the coffee extract by compressing the coffee powder supplied from the grinding unit 141 with high temperature and high pressure water. That is, the coffee liquid extracting unit 150 receives the coffee powder and then applies high-temperature and high-pressure water to allow the water to pass through the filter (not shown) to generate the coffee extract from the coffee powder. The amount and taste of the coffee extract generated in the coffee liquid extracting unit 150 are determined by the amount of the coffee powder injected from the grinding unit 141. Therefore, the input amount of the coffee powder provided to the coffee liquid extraction unit 150 may be adjusted in consideration of the correlation between the input amount of the coffee powder and the production amount of the coffee extract. The amount of coffee extract produced by the coffee extractor 150 is generally proportional to the amount of the coffee powder.

Hereinafter, with reference to Figures 2a to 2b will be described with respect to the crushing unit 141 of the coffee beans manufacturing apparatus 100 according to an embodiment of the present invention.

FIG. 2A is a perspective view illustrating the crushing unit 141 of the coffee bean manufacturing apparatus, and FIG. 2B is a front view of the crushing unit 141.

2A to 2B, the grinder 141 may include a first storage unit 145 for temporarily storing coffee beans supplied from the coffee bean supply unit 139 and a coffee bean stored in the storage unit 145. The cutter 143, the second cutter 144, and a pulverizing unit motor 142 that provides a rotational force to the first cutter 143. And the grinding unit 141 is an adjustment knob 146 for adjusting the interval between the first cutter 143 and the second cutter 144 and the discharge port 147 for discharging the crushed coffee particles to the outside of the grinding unit 141. ).

The accommodating part 145 is formed on the upper part of the grinder 141 to temporarily store the coffee beans supplied from the coffee bean supply part 139. Since the accommodating part 145 has a funnel shape that becomes narrower in width as shown in FIG. 2B, the coffee beans can be smoothly supplied to the first cutter 143 and the second cutter 144. The coffee beans stored in the accommodating part 145 are introduced between the first cutter 143 and the second cutter 144 when the grinder motor 142 is operated to be ground into fine powder.

The first cutter 143 and the second cutter 144 positioned below the accommodating part 145 are disposed to face each other, and the first cutter 143 is coupled to the grinding part motor 142 to rotate. The second cutter 144 is fixed. Therefore, when the grinder 141 operates, the first cutter 143 rotates with respect to the second cutter 144 to grind coffee beans positioned therebetween.

The size of the ground coffee powder is determined by the interval between the first cutter 143 and the second cutter 144. That is, the larger the interval between the first cutter 143 and the second cutter 144, the finer the coffee powder. The distance between the first cutter 143 and the second cutter 144 is determined by adjusting the height of the second cutter 144 by turning the adjustment knob 146 formed on the upper portion of the accommodating part 145.

The discharge holes 147 formed on the side surfaces of the first cutter 143 and the second cutter 144 lead the coffee powder ground in the first cutter 143 and the second cutter 144 to the outside of the grinding unit 141. Provide a passageway. The discharge port 147 is coupled to the side of the crushing unit 141 and extends to the outside by a predetermined length, and the side is closed to prevent the coffee powder discharged at high speed by the rotation of the first cutter 143 from scattering to the outside. Has The coffee powder passing through the discharge port 147 is supplied to the coffee liquid extracting unit 150.

The grinding unit motor 142 of the grinding unit 141 is operated by the control signal of the control unit 160, thereby grinding the coffee beans while the first cutter 143 rotates relative to the second cutter 144. do. Since the grinding unit motor 142 rotates while maintaining a constant rpm, the amount of coffee powder is determined corresponding to the operation time of the grinding unit motor 142. That is, the longer the operation time of the grinding unit motor 142 increases the amount of ground coffee powder. In addition, since the operation time of the grinding unit motor 142 and the amount of the ground coffee powder are generally proportional, the coffee extract liquid extracted from the coffee liquid extraction unit 150 may be adjusted in consideration of this.

Hereinafter, with reference to Figure 3 will be described for the additional raw material supply unit 134 of the coffee beans manufacturing apparatus according to an embodiment of the present invention.

The additional raw material supply unit 134 has a cylindrical shape capable of storing additional raw materials such as sugar, prim and chocolate. In addition, the additional raw material supply unit 134 discharges the additional raw material conveyed by the transfer screw 135 for transferring the additional raw material, the transfer motor 137 and the transfer screw 135 for providing the rotational force to the transfer screw 135 to the outside. And a discharge port 138 that provides a passage.

The feed screw 135 is located in the substantially horizontal direction at the bottom of the feedstock supply unit 134. In addition, blades 136 having constant intervals are formed around the transfer screw 135. The blade 136 rotates together with the transfer screw 135 and serves to push sugar or prim stored in the additional material supply unit 134 toward the discharge port 138. Since the blades 136 have the same shape and spacing along the longitudinal direction of the conveying screw 135, the conveying screw 135 rotating at a constant speed can push an almost constant amount of additional material toward the discharge port 138. have. Therefore, if the rotational force of the transfer motor 137 provided to the transfer screw 135 is kept constant, the transfer screw 135 can push a predetermined amount of additional raw materials in the direction of the discharge port 138 in proportion to the rotation time.

The transfer motor 137 provides a constant rpm to the transfer screw 135. Although not indicated by the reference numeral, the transfer motor 137 is connected to the transfer screw 135 by a geared motor. Since the rotational force provided by the transfer motor 137 is too large as the rotational force of the transfer screw 135, it is possible to stably supply a certain amount of additional raw materials by reducing the rotational speed and increasing the torque.

The discharge port 138 is connected to the lower side of the additional raw material supply unit 134, the lower portion of which is open. And the end of the conveying screw 135 is located in the discharge port 138. Therefore, the additional material moving in the direction of the discharge port 138 by the rotation of the transfer screw 135 passes through the discharge port 138 and falls in the direction in which the discharge port 138 is opened. The additional raw material from the discharge port 138 is introduced into the mixing unit 153 shown in FIG. 1 and then mixed with the water introduced through the mixing unit valve 130 and discharged into the container.

Hereinafter, the setting unit and the display unit 182 of the coffee bean manufacturing apparatus 100 according to an embodiment of the present invention will be described with reference to FIG. 4.

As shown in FIG. 4, the setting unit may select a mode button 174 to select a setting mode, increase / decrease buttons 176 and types of coffee beans to increase / decrease input amount of coffee beans and additional raw materials. And a beverage setting button 178. A display unit 182 is provided between the mode button 174 and the increase / decrease button 176 to display the selected setting mode and to indicate the amount of coffee beans added and the amount of additional raw materials added numerically.

The mode button 174 allows the user to select a setting mode associated with various functions of the coffee bean manufacturing apparatus 100. When the user presses the mode button 174, a different kind of setting mode is displayed on the display unit 182. do. Setting modes that can be set by the mode button 174 include a raw material amount setting mode, a sugar increase / decrease amount setting mode, a cup auto / manual mode, a sales cup number setting mode, a temperature setting mode, and the like.

The raw material amount setting mode is activated by pressing the mode button 174 once, and pressing each button corresponding to each beverage (Americano, Espresso, Cappuccino, Caffe Latte, and Cafe Mocha, etc.) provided in the beverage setting button 178, causes each beverage to be pressed. The input amount of the current coffee powder and additional raw materials for the display unit 182 is displayed numerically or graphically. For example, when the input amount of the coffee powder pulverized in the grinding unit 141 and supplied to the coffee liquid extraction unit 150 is 7 g, the display unit 182 may be displayed as 4.5 seconds, which indicates that the grinding unit 141 is 4.5. By operating for seconds, it means that the coffee beans are ground to 7 g of coffee powder and then provided to the coffee liquid extracting unit 150. In addition, when the input amount of the additional raw material supplied from the additional raw material supply unit 134 to the mixing unit 153 is 3g, the display unit 182 may be displayed as 1 second, which is 3g by operating the additional raw material supply unit 134 for 1 second. It means that the additional raw material of the mixing unit 153 is provided.

In the state where the input amount of the current coffee powder and the additional raw materials for each beverage is displayed, the input amount of the coffee powder can be set, and when the increase / decrease button 176 is pressed, the input amount of the coffee powder can be increased or decreased. That is, when the increase and decrease button 176 is pressed, the display unit 182 is displayed in increments of 4.5 seconds to 0.1 seconds and finally changed to 5 seconds, and the grinder 141 grinds the coffee beans for 5 seconds to 8g coffee. The powder is supplied to the coffee liquid extraction unit 150. When the mode button 174 is pressed again while the input amount of the coffee powder is reset, the input amount of the additional raw material can be set. When the increase / decrease button 176 is pressed, the input amount of the additional raw material can be increased or decreased. . For example, in the case of sugar, pressing the increase / decrease button 176 is displayed in increments of 1 second to 0.1 seconds in the display unit 182 and finally changed to 2 seconds and displayed, and at this time, the sugar supplied from the additional raw material supply unit 134 The amount will increase from 3g to 6.5g.

In the sugar increase / decrease setting mode, the unit setting value of the increase / decrease button 176 can be adjusted. When the consumer wants to drink by adjusting the amount of sugar for the beverage to which the sugar is added, adjust the amount of sugar input using the increase / decrease button 176 and select the beverage, and the amount of sugar is increased or decreased from the sugar value of the corresponding beverage. Is discharged. For example, if the sugar increase and decrease button 176 is pressed before selecting a beverage, the state of increasing or decreasing is displayed on the display unit 182 as a picture, and the amount of sugar to be dispensed is proportional to the number of times of pressing the increase or decrease button 176. To increase or decrease the unit setting value (for example, 0.1 second). When the user selects a beverage, it is dispensed with the adjusted value from the sugar setting value for the selected beverage, and when the dispensing is finished, the user returns to the original setting value. Of course, in addition to sugar, other additives such as prim can be adjusted in the same way.

It is also possible to reduce the input amount of the coffee powder and the input amount of the additional raw material by using the increase and decrease button 176. And in order to be in the setting mode for the other coffee beans, press the beverage setting button 178. In addition, pressing the mode button 174 once more changes to another setting mode state (for example, cup automatic / manual setting mode, sales cup number setting mode, temperature setting mode, etc.).

The cup automatic / manual setting mode determines the use or not of the disposable cup that can be provided inside the coffee bean making machine.If it is automatic, the disposable cup is automatically dispensed and provided externally when it is manually The case of using the cup (for example, a cup of a user) which becomes the following is shown.

The sales cup number setting mode corresponds to a state in which the number of coffee beans sold can be counted from an arbitrary time point when the coffee bean manufacturing apparatus according to the present embodiment is a vending machine.

The temperature setting mode may change the temperature of the water heated in the heater of the heater tank 128, and may increase or decrease the temperature of the water supplied using the increase / decrease button 176. Of course, when the temperature of the water provided from the heater tank 128 is always set to be constant, the coffee bean manufacturing apparatus may not have a temperature setting mode.

The increase / decrease button 176 makes it possible to change each value in the setting mode activated by the mode button 174. As illustrated in FIG. 4, the increase and decrease buttons 176 may include two separate increase and decrease buttons, or may be implemented as one button at which both ends are separate buttons.

The display unit 182 is a portion showing various setting modes displayed by the mode button 174 and numerical values displayed by the increase / decrease button 176. In addition, the display unit 182 is a portion showing various states of the coffee bean manufacturing apparatus 100. The display unit 182 may be implemented by an LCD, but is not limited thereto.

5 is a block diagram illustrating a configuration of the controller 160 according to an embodiment of the present invention.

Referring to FIG. 5, the control unit 160 includes a water supply unit 120, a heater tank 128, a mixing unit valve 130, an extraction unit valve 132, a grinding unit 141, and a coffee liquid extraction unit 150. , Mixing unit 153, coffee beans supply unit 139, additional raw material supply unit 134, power supply unit 164, coin recognition unit 166, cup recognition unit 168, temperature sensing unit 170, setting unit ( 172 and the display unit 182 and controls the overall operation of the coffee beans manufacturing apparatus 100.

The controller 160 may be connected to the water supply unit 120 to determine the amount of water supplied from the water source. That is, a signal for the amount of water identified by the flow meter 122 is transmitted to the controller 160 in FIG. 1, and the controller 160 interprets this signal to determine the amount of water to be introduced and then controls the amount of water to be relief. In addition, the controller 160 controls the vibration pump 124 to supply water introduced into the heater tank 128 and controls the pressure of the water by the relief valve 126 (not shown).

The control unit 160 is connected to the heater tank 128 and when the temperature of the water input from the temperature sensing unit 170 is less than a predetermined value to operate the heater of the heater tank 128. The controller 160 determines the temperature of the water provided to the coffee liquid extracting unit 150 when it is reset and controls the heater tank 128 so that the temperature of the water becomes a reset value.

The control unit 160 controls the mixing section valve 130 and the extraction section valve 132, the amount and timing of the water heated by the heater tank 128 to the mixing section 153 and the coffee liquid extraction section 150 To control.

The controller 160 may control the amount of the coffee powder injected into the coffee liquid extracting unit 150 by controlling the grinding unit 141. As described above, when the grinding unit 141 rotates at a constant speed, the amount of ground coffee powder is constant by controlling the operation time of the grinding unit 141, and the coffee liquid extraction unit 150 is also constant by using the same. A positive coffee extract can be produced. For example, when the grinding unit 141 is rotated for 4.5 seconds to discharge 7 g of the ground coffee powder (in this case, the amount of the coffee extraction liquid generated in the coffee liquid extraction unit 150 is about 35 g). If you change this setting and want a more rich taste for the same type of coffee, change the setting using the increase / decrease button 176 (for example, change the amount of "coffee" from 4.5 to 5 seconds. In this case, it is possible to increase the amount of coffee powder by further lengthening the operation time of the grinding unit 141.

The controller 160 controls the coffee liquid extracting unit 150 to extract the coffee liquid when the coffee powder is input from the grinding unit 141. The controller 160 may control an operation timing of the coffee liquid extracting unit 150 with respect to the mixing unit 153 according to the type of selected coffee beans, which will be described in more detail below.

 The controller 160 controls the mixing unit 153 to mix the additional raw material and water from the additional raw material supply unit 134. In addition, the controller 160 controls an operation timing of the mixing unit 160 with respect to the coffee liquid extracting unit 150 according to the type of coffee beans selected.

Coffee beans may vary depending on the type of coffee extract and added raw materials such as sugar, prim and chocolate. For example, in the case of Americano, café latte or caffe mocha, coffee extract may be added first, and then sugar and prim (or in the case of caffe mocha) may be added. In addition, in the case of cappuccino, the coffee extract may be added after sugar and prim are added first.

In the coffee bean manufacturing apparatus 100 according to the present exemplary embodiment, the controller 160 may control the coffee extract liquid injecting time with respect to the input time of the additional raw material according to the type of the coffee beans selected. Here, the input time of the additional raw material may be determined by the operating time of the mixing unit 153, and the input time of the coffee extract liquid may be determined by the operating time of the coffee liquid extracting unit 150. Therefore, the control unit 160 determines the operation timing of the coffee liquid extraction unit 150 (or the operation timing of the mixing unit 153 with respect to the operation timing of the coffee liquid extraction unit 150) for the operation timing of the mixing unit 153. By the determination, it is possible to determine the timing of injecting the coffee extract with respect to the timing of addition of the additional material.

As described above, when Americano, Caffe Latte or Caffe Mocha is selected, the controller 160 operates the coffee liquid extracting unit 150 first to complete the input of the coffee extract liquid, and then operates the mixing unit 153 to form sugar and prim. (In the case of cafe mocha, including chocolate powder) can be added. In addition, when the cappuccino is selected, the control unit 160 may operate the mixing unit 153 first to inject sugar and prim, and then control the coffee liquid extracting unit 150 to inject coffee extracting liquid.

The control unit 160 controls the coffee beans supply unit 139 and the additional raw material supply unit 134 so that the coffee beans and additional raw materials may be supplied to the grinding unit 141 or the mixing unit 153. Coffee beans supply unit 139 may be made of a feed screw, a transfer motor and a discharge port provided with a blade, similar to the configuration of the additional raw material supply unit 134.

The control unit 160 may control the operation of the coffee bean manufacturing apparatus 100 through the power supply unit 164 and recognize that the coin is input by a signal applied from the coin recognition unit 166. In addition, the controller 160 determines the presence or absence of a cup (for example, a disposable paper cup) inside the coffee bean manufacturing apparatus 100 by a signal applied from the cup recognition unit 168 and determines that there is no cup. In this case, the display unit 182 may display no cup.

In addition, the control unit 160 is connected to the setting unit 172 and stores information on the amount of coffee powder input and the additional raw material input amount set by the setting unit 172. The controller 160 causes the display unit 182 to display information about the coffee powder input amount and the additional raw material input amount set by the user.

The controller 160 is connected to the basic setting switch 162. When the basic setting switch 162 is turned on, the control unit 160 controls the display unit 182 to change the preset value, and when the basic setting switch 162 is turned off, the control unit 160 changes the user setting. The set value is stored in the controller 160, and the coffee beans are manufactured by the changed value.

In addition, the controller 160 may adjust a unit value corresponding to a change in the set value by the operation of the increase / decrease button 176. For example, when the input amount of sugar is changed from 1 second to 2 seconds by the operation of the increase and decrease button 176, the unit value at this time corresponds to 1 second. However, if the unit value is changed to 0.5 seconds to finely adjust the amount of sugar input, pressing the increase / decrease button 176, the amount of sugar is changed from 1 second to 1.5 seconds and the amount of sugar actually added to the mixing unit 153 is It is 6.5 at 3g.

Such a change in unit value can be changed for coffee extracts as well as additional ingredients such as prim and chocolate containing sugar.

Hereinafter, a method for manufacturing coffee beans according to an embodiment of the present invention will be described with reference to specific examples.

Table 1 below shows the input amount of the predetermined coffee powder and additives (sugar and prim) for the cafe latte in the coffee beans manufacturing apparatus 100 according to an embodiment of the present invention. In the table below, the input amount of the coffee powder is set to 4.5 seconds, 7g coffee powder is put into the coffee liquid extracting unit 150, and when 40cc of water is added, 35cc of the coffee extract is generated. Then, when the amount of sugar is 1.0 seconds, 3g of sugar is added to the mixing unit 153, and when the amount of prim is 2.0 seconds, 10g of prim is added to the mixing unit 153. At this time, the amount of water added to the mixing unit 153 corresponds to about 50cc.

When the user wants to adjust the taste of the cafe latte manufactured by the method of Table 1, the setting value is changed using the mode button 174, the increase and decrease button 176 and the beverage setting button 178 as described above. Can be. If the user wants to increase the coffee powder input amount and the sugar input amount after changing to the settable state by operating the basic setting switch 162, the coffee powder input amount is 5 seconds using the increase / decrease button 176 and the sugar input amount is 1.5 seconds. can do. As a result, the input of the coffee powder according to the changed value is 8g and the input of sugar is 10g. At this time, the controller 160 determines whether the setting value for the input amount of the coffee powder and the additional raw material is changed, and stores the changed setting value when the user turns off the basic setting switch 162. In this case, the setting values stored in the controller 160 are shown in Table 2 below.
