Description

Inverter dough conditioner {INVERTER DOUGH CONDITIONER}

The present invention relates to an inverter dough conditioner, and more particularly, to an inverter dough conditioner configured to precisely control the temperature and humidity inside the main body.

In general, bread is baked or steamed after fermenting flour and a certain amount of water, and the main ingredients of such bread are flour, yeast, salt, and water. Depending on the type of bread, sugar, eggs, edible oil and other ingredients are mixed. Bread dough made by fermentation is baked or steamed.

In order to produce such bread in large quantities, it is very important to ferment a large amount of dough (bread dough) at the same time under the same conditions, and a dough conditioner can ferment a large amount of dough at the same time under the same conditions.

In this way, in the case of manufacturing bread using the dough conditioner, the dough conditioner automatically performs freezing, thawing, and fermentation steps to manufacture bread according to a preset command control.

In order to produce a uniform bread with this dough conditioner, it is very important to control the temperature and humidity of the dough. However, in the conventional dough conditioner, for example, since the internal temperature and humidity of the main body are controlled through a fixed-speed compressor operated in an ON/OFF disconnection method, it is difficult to precisely control the internal temperature and humidity of the main body.

In other words, in the conventional dough conditioner, there is a problem in that the temperature and humidity inside the main body, which are actually operated based on the required temperature and humidity previously specified by the user, have a large deviation compared to the reference temperature and humidity. Bread manufactured from such a conventional dough conditioner has problems in that air bubbles inside the bread are irregular, and the skin condition of the bread is not smooth.

In addition, the dough conditioner equipped with a fixed-speed compressor operated by the ON/OFF disconnection method operates the compressor, so failure due to instantaneous overcurrent and current consumption increase due to the repeated ON/OFF operation method, as well as machine operation. Noise also has a big problem.

Accordingly, various research and development have been made on dough conditioners made to precisely control the internal temperature and humidity of the main body.

One such accommodation space 101 may be formed in the main body 100, two or more may be formed, etc., the number of the accommodation space 101 may be variously configured according to the purpose of use. .

For example, if two accommodating spaces 101 are formed in the main body 100, a freezing process is performed in one accommodating space 101, and thawing and defrosting in the other accommodating space 101 The fermentation process can also be carried out.

An operation part 120 is provided on the upper part of the main body part 100.

Meanwhile, the sensor module 200 is provided inside the main body 100 and is configured to measure an internal environmental condition of the accommodation space 101. Here, the internal environmental conditions of the accommodation space 101 measured by the sensor module 200 may be a temperature and a humidity state.

The information measured from the sensor module 200 is transmitted to the central controller 600, and the central controller 600 precisely controls the operation of the inverter dough conditioner 1000 based on the information measured from the sensor module 200. Is done. Such a central control unit 600 may be provided inside the main body 100.

Here, the sensor module 200 is preferably installed on the front side of the upper frame in forming the accommodation space 101 by connecting a plurality of frames. It goes without saying that the location and number of the sensor modules 200 are not necessarily limited to a specific location and number, and can be installed in various forms.

The configuration of the sensor module 200 will be described in detail later.

On the other hand, the humidification heating unit 300 is provided inside the body unit 100.

The humidification heating unit 300 may include a heating heater unit 310 and a spray unit 320.

Here, the heating heater unit 310 is configured to increase the temperature inside the body unit 100 through selective heating.

The heating heater unit 310 may be configured in a form in which, for example, a plurality of polygonal heat sinks are spaced apart from each other at predetermined intervals in a heating unit that generates heat. Since the heating heater 310 needs only to adjust the number of heat sinks according to the capacity and size of the inverter dough conditioner 1000, it is possible to custom manufacture according to the capacity and size of the inverter dough conditioner 1000.

In addition, the polygonal heat sink may have a wide contact area with water sprayed from the spray unit 320. Accordingly, humidification inside the main body 100 can be effectively performed.

In addition, an overheating blocking part (not shown) may be further provided inside the main body 100. When the internal temperature of the main body 100 is equal to or higher than a predetermined temperature, the overheat prevention blocking unit automatically stops the operation of the humidification heating unit 300.

For example, the overheating blocking unit is electrically connected to the central control unit 600, but when the internal temperature of the body unit 100 is higher than a predetermined temperature, the operation of the humidification heating unit 300 through the central control unit 600 is You can also control it. Alternatively, the overheating prevention blocking unit may be directly connected to the humidifying heating unit 300, so that the overheating prevention blocking unit may directly stop the operation of the humidifying heating unit 300.

Meanwhile, the cooling module 400 is configured to adjust the internal environment of the main body 100. That is, the cooling module 400 is configured to control the temperature and humidity inside the main body 100 together with the humidification heating unit 300.

Such a cooling module 400 may include a compressor 410, a condenser 420, and an evaporator 430.

Here, the compressor 410 is provided on the main body 100. The compressor 410 controls the incoming refrigerant to a predetermined high temperature and high pressure state. The operation of the compressor 410 may be controlled by the central control unit 600. At this time, the central control unit 600 does not control the compressor 410 through a conventional ON/OFF disconnection method, but applies a predetermined control frequency to the compressor 410 for each process step, thereby accurately controlling the compressor 410 Is made to control. Here, the control frequency may be PWM (Pulse Width Modulation).

In other words, the central control unit 600 applies a control frequency to the compressor 410, and the compressor 410 is a rotor (not shown) provided in the compressor 410 according to the control frequency applied from the central control unit 600. ) By controlling the number of revolutions, the compressor 410 can be precisely controlled.

In this way, when the compressor 410 is operated by the control frequency applied from the central control unit 600, the compressor 410 can be continuously operated without being disconnected, so that power consumption can be minimized. In addition, the compressor 410 may minimize an internal temperature error range of the main body 100 even when controlling the inside of the main body 100 to a predetermined temperature range. Therefore, in manufacturing bread, the user can manufacture bread in the correct temperature range for each process step. This compressor 410 may be controlled by an inverter method.

In addition, the condenser 420 is provided on the upper part of the main body 100 and is configured to deliver the refrigerant to the evaporator 430 while the temperature of the refrigerant delivered from the compressor 410 is lowered.

And the evaporator 430 is provided inside the main body 100. The evaporator 430 adjusts the internal temperature of the main body 100 to a required temperature through evaporation of the refrigerant delivered from the condenser 420. Such an evaporator 430 may be provided under the humidification heating unit 300.

In this way, the evaporator 430 provided under the humidification heating unit 300 may generate moisture during cooling and defrosting. Here, when the fermentation step of the inverter dough conditioner 1000 begins, the humidification heating unit 300 arranged in close contact with the top of the evaporator 430 evaporates the cooled moisture generated in the evaporator 430 during the cooling and defrosting process. And, by minimizing evaporation of moisture contained in the dough during freezing operation, it is made to maintain an optimal fermentation state in which the frozen dough is neither dry nor wet during the fermentation process.

Accordingly, the inverter dough conditioner 1000 can quickly increase the humidity inside the accommodation space 101 in the fermentation step. In this way, due to the constitutive arrangement of the evaporator 430 disposed under the humidification heating unit 300, the inside of the main body 100 can be effectively humidified.

Referring to Figures 3 to 5, Figure 3 is a graph showing the internal temperature state of the main body 100 at each process step, the bread manufactured from the inverter dough conditioner 1000 is frozen step (S1), thawing step (S2) ) And the fermentation step (S3).

Here, the temperature and humidity inside the main body 100 may be precisely controlled by control values applied from the central control unit 600 to the respective components such as the compressor 410 and the blower 500.

The central control unit 600 that controls the configuration of each device of the inverter dough conditioner 1000 is configured to enable firmware, so that software upgrade of the inverter dough conditioner 1000 is possible.

Table 1 below is a table showing the control states of the compressor 410 and the blower 500 controlled by the central control unit 600 for each process step.

As shown in FIG. 3 and Table 1, in the case of the refrigeration maintenance transfer mode, the inverter dough conditioner 1000 rapidly cools the internal temperature of the main body 100 at room temperature.

In this case, the central control unit 600 sets a control frequency of 50 to 67 Hz so that the internal temperature of the main body 100 is adjusted from room temperature to -10°C in the refrigeration maintenance transfer mode of the freezing step (S1). It is applied to to control the operation of the compressor 410. In this case, the number of rotations of the rotor provided in the compressor 410 may be rotated at 3000 to 4020 rpm.

In addition, the central control unit 600 controls the operation of the blower unit 500 within a control voltage range of 3.7 to 4.0 V for a predetermined internal temperature of the body unit 100 in the freezing maintenance transfer mode of the freezing step (S1). do. In this case, the number of rotations of the blowing fan provided in the blowing unit 500 may be rotated at 2900 to 3400 rpm. The blower 500 circulates air inside the accommodation space 101 so that a uniform temperature and humidity can be maintained at any position in the accommodation space 101. Here, the control voltage for controlling the operation of the blower 500 may be a brushless direct current (BLDC) driving control voltage Vsp.

In this way, in the refrigeration maintenance transfer mode of the refrigeration step (S1), the central control unit 600 controls the compressor 410 and the blower 500 as described above, so that the refrigeration maintenance transfer mode of the inverter dough conditioner 1000 is effectively Let it happen.

Here, referring to FIG. 4, in controlling the compressor 410 and the blower 500 from the central control unit 600 as described above to control the internal temperature of the main body 100 to the temperature of the refrigeration maintenance mode, 33 minutes It satisfies the required internal temperature of the main body 100 within a fast enough time.

In addition, the central control unit 600 applies a control frequency of 30 to 67 Hz to the compressor 410 so that the internal temperature of the main body 100 is adjusted to -10°C in the freezing maintenance mode of the freezing step (S1). It will control the operation of 410. In this case, the number of rotations of the rotor provided in the compressor 410 may be rotated at 1800 to 4020 rpm.

In addition, the central control unit 600 controls the operation of the blower unit 500 within a control voltage range of 3.3 to 3.7V for a predetermined internal temperature of the body unit 100 in the freezing maintenance mode of the freezing step (S1). . In this case, the number of rotations of the blowing fan provided in the blowing unit 500 may be rotated at 2200 to 2900 rpm.

In this way, in the refrigeration maintenance mode of the refrigeration step (S1), the central control unit 600 controls the compressor 410 and the air blower 500 as described above, so that the refrigeration maintenance mode of the inverter dough conditioner 1000 is effectively achieved. do.

Here, referring to FIG. 5, when controlling the compressor 410 and the blower 500 from the central control unit 600 as described above to adjust the internal temperature of the main body 100 to the refrigeration maintenance mode, according to the present invention. It can be seen that the inverter dough conditioner 1000 maintains a temperature deviation range of ±0.2°C based on -10°C in the internal temperature of the main body 100 as shown in FIG. 5A. On the other hand, it can be seen that in the dough conditioner equipped with a compressor controlled by the conventional ON/OFF method, the internal temperature of the main body 100 shows a large temperature deviation of ±2°C based on -10°C.

In addition, the central control unit 600 applies a control frequency of 20 to 30 Hz to the compressor 410 so that the internal temperature of the main body 100 is maintained at 0 to 3°C in the defrosting maintenance mode of the defrosting step (S2). ) To control the operation. At this time, the number of rotations of the rotor provided in the compressor 410 may be rotated at 1200 ~ 1800rpm.

In addition, the central control unit 600 controls the operation of the blower unit 500 within a control voltage range of 3.3 to 4.0 V for a predetermined internal temperature of the body unit 100 in the defrosting maintenance mode of the defrosting step (S2). . At this time, the number of rotations of the blowing fan provided in the blowing unit 500 may be rotated at 2200 to 3400 rpm.

In this way, in the defrosting maintenance mode of the defrosting step (S2), the central control unit 600 controls the compressor 410 and the blower 500 as described above, so that the defrosting maintenance mode of the inverter dough conditioner 1000 is effectively achieved. do.

And the central control unit 600 is the compressor 410 with a control frequency of 0 to 20 Hz so that the internal temperature of the main body 100 is maintained at 3 to 40°C in the first fermentation mode and the second fermentation mode of the fermentation step (S3). It is applied to to control the operation of the compressor 410. At this time, the number of rotations of the rotor provided in the compressor 410 may be rotated at 0 ~ 1200rpm.

In this way, in the first fermentation mode and the second fermentation mode of the fermentation step (S3), the central control unit 600 controls the compressor 410 and the blower 500 as described above, thereby defrosting the inverter dough conditioner 1000. Make the maintenance mode effective.

Here, in the first fermentation mode, the internal temperature of the main body 100 is increased from 3℃ to 20℃, and in the second fermentation mode, the internal temperature of the main body 100 is increased from 20℃ to 40℃. , Can shape the volume of bread.

In this way, the central control unit 600 is applied to the compressor 410 and the blower 500 at each step in the process of performing each process of the freezing step (S1), the thawing step (S2) and the fermentation step (S3). This numerical range is a very important control reference range for making the best bread.

If the numerical range applied to the compressor 410 and the blower 500 in each step of the process is out of the range, the upper and lower temperature deviation of the accommodation space 101 may be largely generated, and the inverter dough conditioner 1000 The power consumption for the operation of the bread may be increased, and there is a problem that the required quality level of various breads such as the skin color of the manufactured bread, the surface air bubbles of the bread, the uniformity of the bubbles in the bread, and the volume of the bread cannot be satisfied.

As shown in Figure 6, the bread manufactured in the present invention and in a state that satisfies the numerical ranges applied to the compressor 410 and the blower 500 in each process step (Example) and the bread (Comparative Example) not It can be seen that there is a big difference in the quality of bread such as the color of the skin of the prepared bread, the surface air bubbles of the bread, the uniformity of the air bubbles in the bread, and the volume of the bread.

Herein, when the refrigeration maintenance mode state is described as an example, when the central control unit 600 controls the compressor 410 and the blowing unit 500, the control frequency applied to the compressor 410 is less than 30 Hz, and the blowing unit When the voltage applied to 500 is less than 3.3V, there is a problem in that a temperature difference between the upper and lower portions of the accommodation space 101 is largely generated. In this case, there is a problem in that the manufacturing state of the dough finally prepared from the dough disposed on the upper portion and the dough disposed on the lower portion is not uniform.

And when the central control unit 600 controls the compressor 410 and the blower 500, the control frequency applied to the compressor 410 is greater than 67Hz, and the voltage applied to the blower 500 is greater than 3.7V. In this case, there is a problem in that unnecessary power use is largely generated.

In this way, the central control unit 600 applies a predetermined numerical value to the compressor 410 and the blower 500 for each step of the process, so that the finally produced bread can be made into a high-quality bread, the inverter dough conditioner 1000 ) To control the operation.

Each component provided in the 1000 is controlled.

The sensor module 200 measures the temperature and humidity of the accommodation space 101 at predetermined time intervals, and then provides the corresponding information to the central control unit 600. Here, the measurement time interval of the sensor module 200 may be, for example, 30 to 60 seconds, but is not necessarily limited to the corresponding time interval, and the temperature and humidity of the accommodation space 101 may be measured at various time intervals. Yes, of course.

Here, since the central control unit 600 controls the inverter dough conditioner 1000 as a whole based on information provided from the sensor module 200, it is very important to accurately measure the temperature and humidity of the sensor module 200.
