Description

TECHNICAL FIELD [0001] The present invention relates to an ice cream manufacturing apparatus and an ice cream dispensing method,

TECHNICAL FIELD [0001] The present invention relates to an ice cream producing apparatus and an ice cream delivering method, and more particularly, to a technique for producing an ice cream having an optimal ice quality and a technique for making the amount of ice cream uniform when the ice cream is dispensed.

Generally, a soft ice cream has a soft ice quality (quality) that is lower than that of a frozen ice cream by changing the liquid ice cream stock into a slightly frozen ice cream by mixing it with air using a cooling means. The ice cream thus produced is kept in the ice cream producing apparatus until the ice cream is discharged. When the ice cream is dispensed, the fresh ice cream is mixed with the prepared ice cream to regenerate the ice cream.

The ice content of the soft ice cream is mainly determined by the evaporation temperature of the evaporator in the cylinder, the rotation speed of the washer, the temperature at the control point, the temperature of the ice cream stock solution, and the amount of over-run of the air.

The ice cream is produced through an initial stage of producing an ice cream from a liquid ice cream stock solution and a post-injection stage where a fresh stock solution is mixed with the ice cream after the ice cream is produced after the ice cream is produced. And the ice cream produced in this way is maintained in the ice cream manufacturing apparatus until the ice cream is discharged.

It is necessary to rotate the Daisha motor at a high speed in order to secure the ice quality in the initial stage of generating ice cream from the liquid ice cream stock solution and the post-delivery stage of regenerating the ice cream after the ice cream is dispensed. When the ice cream is kept and stored, it is divided into a storage step for storing ice cream produced by stopping the Daisha motor and a maintenance step for regenerating some melted ice cream again with ice cream. In the maintenance step, the Dasher motor is rotated again.

However, if the rotational speed of the Dacer motor is not appropriately adjusted at each step, the ice cream overrun, the strength, the particle size, and the viscosity become different, and the ice cream texture, ice quality and the amount of discharge per unit time continuously change. Further, the viscosity of the ice cream, the degree of melting of the inside of the cylinder and the degree of melting of the ice cream in the outside of the cylinder, and the like are different from each other in a stepwise manner.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention are described in order to more fully explain the present invention to those skilled in the art, and the following embodiments may be modified into various other forms, The present invention is not limited to the embodiment. Rather, these embodiments are provided so that this disclosure will be more faithful and complete, and will fully convey the scope of the invention to those skilled in the art.

In the figures, for example, variations in the shape shown may be expected, depending on manufacturing techniques and / or tolerances. Accordingly, embodiments of the present invention should not be construed as limited to any particular shape of the regions illustrated herein, including, for example, variations in shape resulting from manufacturing. The same reference numerals denote the same elements at all times. Further, various elements and regions in the drawings are schematically drawn. Accordingly, the invention is not limited by the relative size or spacing depicted in the accompanying drawings.

FIG. 1 is a view for explaining a process of generating ice cream, showing a cylinder internal structure.

Referring to FIG. 1, a liquid ice-cream stock solution and air are introduced into a closed cylinder 101 through a charging port 103 through a carburetor. The liquid ice-cream stock solution is stirred in the inside by the rotating shoe 107, and the ice-cream stock solution and air are mixed to form an over-run. Heat exchange is caused by an evaporator (not shown) in the inner wall of the cylinder, and a phase change occurs in the inner wall of the cylinder. That is, solidification by heat exchange results in a liquid ice-cream stock solution becoming a solid ice-cream. At this time, the current of the Daisha motor changes due to the load change due to the phase change from the liquid to the solid.

Thus, the solidified ice cream is pulverized by the blade 105 and the bundle of the damascene structure in accordance with the rotation of the dasher 107. The crushed ice cream is mixed with the inner stock solution by the rotation of the dasher 107. As these processes are repeated, the inner ice cream mixes solid particles, liquid, and air properly. Thereafter, when the Dasher cover (not shown) in the direction of ejection is opened, the soft ice cream in a state in which the solid particles and air are appropriately mixed is discharged to the outside by the internal pressure.

At this time, if the rotating speed of the dasher 107 is increased, the number of times the stack of structures and the blade 105 pass through the inner wall of the cylinder per unit time increases. As a result, the solidification time of the ice cream is shortened. Then, the size of the first ice-cream producing particle becomes small. On the other hand, if the rotation speed is slowed down, the size of the ice cream generating particle becomes large. However, as the ice cream raw material, which is a mixture of different components below the freezing point, continues to rotate for the duration of the washer 107, the separation phenomenon of the foreign matter is accelerated by friction (contact between particles). For this reason, the rotation speed and the operation time adjustment of the Dasher 107 are very important factors for ice cream production and ice ice quality. Accordingly, an embodiment of the present invention for improving the ice quality of the ice cream by controlling the rotational speed of the washer 107 will be described.

FIG. 2 is a block diagram showing a schematic configuration of an ice cream production apparatus according to an embodiment of the present invention, FIG. 3 is a graph showing a correlation of torque according to a frequency of a Daishag motor, FIG. Fig. 8 is a flowchart showing the operation of the ice cream production apparatus according to the embodiment.

Referring to FIG. 2, an ice cream production apparatus 100 according to an embodiment of the present invention includes a Dasher 107, a Daisha motor 109, a motor drive unit 111, a motor rotation speed control unit 115, a power supply unit 117, a Daishier motor load measuring means 119, a control unit 121, and a discharge port 123. In addition, the detailed configuration of a general ice cream manufacturing apparatus is also included, such as the configuration of an input unit (not shown), a voice guidance unit (not shown), a display unit (not shown), a freezing unit (not shown) and a refrigerator And only the configuration according to an embodiment of the present invention is shown in FIG.

Here, each constitution of the ice cream producing apparatus 100 will be described as follows. The dasher 107 is in the form of a screw and is located inside the cylinder (101 in Fig. 1). The dasher 107 agitates the ice cream stock solution and the air injected into the closed cylinder while rotating, and then transfers the generated soft ice cream to the front of the cylinder.

The Dasher motor 109 rotates at a rotational speed corresponding to the frequency of the driving power supplied from the motor rotational speed regulating means 115. At this time, when the rotation speed of the Daishag motor 109 is low, the friction of the ice cream is reduced by rotating the dasher 107 at a relatively low rotation speed, so that the ice quality of the ice cream inside the cylinder can be maintained in an optimal state. When the rotation speed is high, the ice maker 107 is rapidly rotated at a relatively high rotation speed, thereby rapidly transferring the ice cream inside the cylinder to the front of the cylinder.

The motor driving unit 111 is constituted by a circuit for driving the motor 113 by switching the driving power output from the motor rotation speed regulating means 115. When the motor driving unit 111 is supplied with driving power having a frequency of 20 to 100 Hz, the motor driving unit 111 rotates the Daehler motor 109 at a speed of about 40 to 200 RPM to rotate the busher 107 at a low speed. When the driving power having a frequency of 50 to 200 Hz is supplied, the motor 105 is rotated at a speed of about 100 to 400 RPM to rotate the busher 107 at a high speed.

The motor rotation speed control means 115 converts the frequency of the driving power supplied from the power supply 117 to a frequency requested by the control unit 121 and supplies the frequency to the motor driving unit 111, Adjust the rotation speed. For example, the motor rotation speed control unit 115 increases the frequency of the operating power having the frequency of 20 to 100 Hz outputted from the power supply unit 117 so as to have a high frequency of about 50 to 200 Hz . On the other hand, the frequency can be reduced and output.

The ice cream is discharged through the discharge port 123 and the outlet 123 is supplied with power from the power supply unit 117 and is opened for a time requested by the control unit 121 so that the ice cream is discharged.

The power supply unit 117 outputs driving power having a predetermined frequency.

The Dascher motor load measuring means 119 measures the load of the Daishag motor 109, converts the measured load value to be recognizable by the control unit 121, and outputs it to the control unit 121. [ The Dasher motor load measuring means 119 may be a Daehler motor current measuring means for measuring the current of the Daishag motor 109 or a Daehler motor speed measuring means for measuring the revolutions per unit time of the Daishier motor 109.

The controller 121 controls components of the ice-cream maker 100 to control the generation and ejection of ice cream. The control unit 121 variably controls the rotation speed of the Daeha-motor 109 in accordance with conditions such as ice cream generation, maintenance, and ejection using the motor rotation speed control means 115. [ In one embodiment, when the revolutions per unit time of the Daehler motor 109 measured by the Daehler motor load measuring unit 119 reaches the predetermined number of revolutions per unit time or the number of revolutions per unit time changes, If the frequency of the driving power supplied to the Daehaser motor 109 is changed by controlling the motor rotation speed control means 115 to maintain the ice structure of the Daehler motor 109 at an optimal state, can do.

Here, the torque of the Daishag motor 109 is expressed by Equation (1).

Figure pat00001

Where Tm is the torque, K is the motor torque constant,? Is the magnetic flux, I is the current, F is the frequency and V is the voltage.

The correlation of the torque according to the frequency is shown in Fig. Therefore, if the frequency of the driving power supplied to the Daisha motor 109 is changed, the rotating speed of the Daisha motor 109 is changed, and the resistance force of the Dasher 107 varies depending on the frequency. That is, a change in the required torque occurs. By substituting this into Equation 1, it can be seen that the current changes when it is assumed that the state of the inner cylinder 101 is the same for each frequency. When K, V, and Tm are constant when the frequency changes in the same torque region, and when F changes, I also fluctuates. In addition, even if the resistance force of the shock absorber 107 is the same, the current measured by the Daisha motor 109 can be changed by the deviations by device and motor.

Therefore, when the current of the Taescher motor 109 measured by the Daishier motor load measuring means 119 reaches a preset current or a constant current changes, the controller 121 keeps the ice ice of the ice cream in an optimal state The rotational speed of the Daisha motor 109 can be set to a desired speed by changing the frequency of the driving power supplied to the Daisha motor 109 by controlling the motor rotational speed control means 115. [

4, first, the control unit 121 determines the rotational speed changing point of the Daeha-motor 109 based on the load of the Daehsler motor 109 measured by the Daehler motor load measuring unit 119 (S101). As described above, the Daehler motor load measuring means 119 can measure the current or the number of revolutions per unit time of the Daehler motor 109. Next, it is determined whether the measured load of the sander motor 109 satisfies a specific condition (S103). Here, the specific condition is, for example, whether the measured current or the number of revolutions per unit time reaches a pre-input current or the number of revolutions per unit time, or whether the measured current or the number of revolutions per unit time changes. That is, it is determined whether or not the current or the current measured by the motor / generator 109 or the number of revolutions per unit time, the constant current, or the number of revolutions per unit time changes in advance with respect to the current input to the control unit 121 or the number of revolutions per unit time, In this case, the control unit 109 determines that time point as a time point at which the speed of the motor 109 is changed (S105). The current conversion time point may be set to the delta current (I), and the conversion time point per unit time may be set to the number of rotations per unit time DELTA RPM.

Although not shown in FIG. 4, in the embodiment, when a predetermined time elapses after the driving of the Daehler motor 109 at a constant current or per unit time, It can be determined that the rotation speed is changed.

When the rotation speed change of the Daisha motor 109 is determined, the frequency of the Daisha motor 109 is changed (S107) to adjust the rotation speed of the Daisha motor 109. [ The control unit 121 outputs a preset frequency to the motor rotation speed control unit 115 to change the frequency of the motor driving unit 111 to a predetermined frequency so as to change the driving power frequency of the motor driving unit 111.

That is, when the Daisha motor 109 is driven at the first frequency and the load measured by the Daisha motor 109 satisfies the above-described specific condition, the point of time is determined as the point of time when the Daisha motor 109 is changed, (109) to a second frequency that is different from the first frequency.

Here, in the initial ice cream producing step, since the liquid ice cream stock solution is formed of solidified ice cream, a frequency for a relatively high rotational speed, for example, 50 to 120 Hz is required. In the stage where the solidified ice cream is maintained, the ice cream is melted with the lapse of time, and the shape and texture of the ice cream are maintained over time. Therefore, the frequency for a relatively low rotation speed, for example, 80 Hz is required. Based on this point, the control unit 121 determines the frequency of the driving power output from the motor rotation speed control means 115. The control unit 121 adjusts the rotation speed of the dasher 107 in accordance with the ice cream producing step to maintain the texture and shape. The same ice condition (state) is maintained by measuring and controlling the current or the number of revolutions per unit time of the Daisha motor 109 at the control point in spite of the change of the rotation speed according to the generation step.

FIG. 5 is a graph showing an ice cream production interval according to an embodiment of the present invention, and FIG. 6 is a graph showing a current measured by the Daisha motor at the time of ice cream production.

Referring to FIG. 5, changes in behavior due to ice cream production are roughly classified into four stages, as shown in Table 1 below.

Step name Explanation First creation step
(First) The raw liquid in a liquid state is generated as an ice cream containing solid air. Maintenance phase
(Run) Maintains the built-in ice cream and regenerates some melted ice cream The dispensing phase
(Draw) It generates ice cream with an internal pressure higher than a certain level and emits ice cream. Post-Dispatch Step
(After draw) Regenerated by mixing liquid raw liquid and solid ice cream properly

According to Table 1, the first generation step (First) creates a liquid state raw ice cream as a solid state ice cream. At this time, the ice cream producing behavior is formed in the inner wall of the cylinder 101, and the crushed solid particles are mixed with the liquid inside and then mixed with the crushed solid particles to form ice cream. If the rotation speed is slow, the ice cream is reduced in bubbles and air entrainment, thereby reducing the overrun and softness and reducing the heat transfer to form ice cream having a relatively large solid particle size. If the particles become larger than a certain size, they will have rough texture like sherbet, so the particles must be controlled to a certain size or less. It is also important to create an ice cream with the appropriate level of friction (contact between particles) and cold air. If the machine is operated for a long period of time at a high rotational speed, friction is generated more than necessary, and the components of the ice cream mixture are separated by physical properties and the ice cream particles become larger and thinner. Therefore, high-speed operation is required first in the initial generation stage.

Next, the maintenance step (Run) maintains the ice cream made inside the cylinder and regenerates some melted ice cream. At this time, the ice cream generation behavior is mixed with the ice cream remaining inside while solidifying some melted ice cream on the outer wall. If the rotation speed is fast, the particles of the ice cream to be replenished are made finely, but the ice cream already existing in the ice is also accelerated by crushing and friction. When friction (contact between particles) increases below the freezing point, the same material binds due to its physical properties, the foreign matter is separated, the particles become large and coarse, and cause the phenomenon of thinning. Therefore, a relatively low rotational speed (40 to 200 rpm) is required.

Next, the dispensing step (Draw) generates an internal pressure equal to or higher than a certain level in the ice cream produced inside, thereby to eject the ice cream to the outside. When the dasher 107 is rotated at a constant speed or more, internal pressure is generated. At this time, when the discharge port 123 of the dasher cover is opened, the inner ice cream is discharged and the amount of the original liquid and air is replenished. At this time, if the rotation speed of the shock absorber 107 is slow, the pressure at the cylinder inlet becomes low and the injection is slowed down. Therefore, a relatively high rotation speed (100 to 400 rpm) is required since a speed at which a certain pressure or more can be assured is required.

Next, the after-draw step is regenerated by appropriately mixing the raw liquid in the liquid state and the ice-cream in the solid state. Mix and regenerate as much as the amount of the injected liquid and the remaining ice cream. At this time, the amount of the original liquid and the air introduced into the ice cream amount has been introduced, and it is a process of mixing and regenerating some remaining ice cream. Since the post-discharge step is characterized by the intermediate nature between initial generation and maintenance, it is necessary to adjust the size of the particles so as to increase the overrun and promote the heat transfer by injecting a large amount of air into the liquid stock solution through relatively high- A higher rotation speed (100 to 400 rpm) is required.

Although not shown in Table 1, as shown in Fig. 5, after the ice cream is produced (initial generation step) or regenerated (maintenance step, after the projecting step), the stored ice cream (solidified ice cream) There is a step Break.

However, since there is a difference in the rotational speeds required even within the same step, it is difficult to generate ice cream having the same ice quality in each step in the rotational speed control of the four steps described in Table 1 simply. That is, with the ice cream generating method of the four steps described in Table 1, there is a limit to keeping the ice cream of the ice cream constant.

Accordingly, among the four ice cream production methods described in Table 1, the initial production stage and the post-delivery stage may be subdivided into six stages or more.

The initialization step (First Speed) of Table 1 is divided into an initial generation period (First Speed # 1) and a late generation period (First Speed # 2). The after draw of Table 1 is divided into the after draw speed # 1 and the after draw speed # 2.

At this time, the initial generation period (First Speed # 1) and the after-draw-up period (After draw Speed # 1) are high-speed operation stages and the over-run is applied, minimizing the particle size by increasing heat transfer, to be. In the low-speed operation stage, the same load control of the ice cream in the cylinder 101 maintains a constant ice cream, excessive friction (inter-particle contact), and the like. And the ice cream separation phenomenon should be minimized. Then, the late generation section (First Speed # 2) and the after-draw section (After draw Speed # 2) rotates the Daehler motor 109 at the same or similar frequency as the holding step of Table 1.

Therefore, the ice cream generating section according to the embodiment of the present invention may include a first generation section P1 as an initial generation section (First Speed # 1), a second generation section P3 as a late generation section (First Speed # 2) A fourth generation section P7 as a projecting stage of Table 1, a fifth generation section P9 as an after draw speed # 1 stage, and a post-projecting stage P8 as a post- (After draw Speed # 2), and a sixth generation interval P11. In addition, a storage step (Break Time) is provided between the second generation interval P3 and the third generation interval P5, between the third generation interval P5 and the fourth generation interval P7, and after the sixth generation interval P11, .

Here, the high-speed rotation section of the Daishag motor 109 is a first generation section P1, a fourth generation section P7 and a fifth generation section P9. The low-speed rotation section of the Daisha motor 109 is a second generation section P3, a third generation section P5 and a sixth generation section P11.

At this time, the controller 121 generates ice cream at a high speed in the first generation interval P1 and ice cream at a relatively low rotation speed in the second generation interval P3, for example, at the rotation speed of the maintenance step P5 . Likewise, in the fifth generation period P9, ice cream is generated at a high speed, and in the sixth generation period P11, the ice cream is controlled at a relatively low speed, for example, the speed of the maintenance stage P5.

As described above, the control unit 121 can control the second generation period P3 and the sixth generation period P11 in the same or similar to the rotation speed of the third generation period P5. At this time, the control unit 121 may determine the control point based on the load measured by the motor load measurement unit 119, or may determine based on the elapsed time of the first generation interval P1 and the fifth generation interval P9 . The Daishier motor load measuring means 119 can measure the current or the number of revolutions per unit time of the Daishag motor 109. In this case, when the current or the number of revolutions per unit time reaches the current or the number of revolutions per unit time, or the constant current or the number of revolutions per unit time is changed, the control unit 121 generates the second generation period P3, It is possible to control the rotational speed of the dasher 107 in the sixth generation interval P11.

6 is a graph showing the current of the Daisha motor at the time of ice cream production.

Referring to FIG. 6, when the liquid phase ice cream is mixed with the air, that is, in the first generation period P1, the current starts to change and the ice cream stock solution starts phase change from solid to liquid, Lt; / RTI > That is, if the load applied to the Daisha motor 109 changes due to a phase change, the load can be detected as a change in current (? I). Therefore, when the time P at which the current change? I is detected, the time at which the current reaches the specified value, or the predetermined elapsed time? T elapses, the operation state change of the motor 109, .

In the first generation period P1, only the liquid source ice cream liquid and air are present, so that the measured current is constant. The controller 121 monitors the current and determines that the second generation interval P3 starts when the current change ΔI and the current time reach a specific value or a predetermined elapsed time Δt has elapsed And changes the frequency of the power supplied to the Daisha motor 109 to the frequency of the third generation interval P5. When the controller 121 detects that the current measured in the fifth generation period P9 after the ice cream is discharged is constant (? I), the current reaches the specified value or the predetermined elapsed time? T has elapsed, It is determined that the sixth generation interval P11 is started and the frequency of the power supplied to the Daisha motor 109 is changed to the frequency of the third generation interval P5 or a similar frequency.

6 shows only the current measured by the Daisha motor 109 at the time of ice cream production, but it is also similar to the number of rotations per unit time measured by the Daishag motor 109. Fig. That is, when the liquid phase ice cream is mixed with the air, that is, in the first production interval P1, the number of rotations per unit time is constant and when the liquid phase of the ice cream starts to change from solid to liquid, The second generation period P3 and the sixth generation period P11 start point can be determined through the time point at which the number of revolutions per unit time reaches a specific value or the change in revolutions per unit time (DELTA RPM) , The control unit 121 may change the frequency of the power supplied to the Daisha motor 109 to the frequency of the third generation period P5 or a similar frequency.

As described above, the control unit 121 can know the time at which the ice cream is generated from the current measured by the Daehler motor load measuring unit 110 or the number of revolutions per unit time. Therefore, the control unit 121 recognizes the change time point of the rotation speed of the damper 107 and changes the rotation speed of the Daehisa motor 109 from high speed to low speed to control the speed to a low speed state so as to always maintain the strength and ice- .

FIG. 7 is a diagram showing the behavior of ice cream particles at the time of ice cream production, and is a view for explaining effects according to the embodiment of the present invention.

Here, FIG. 7 (a) shows ice cream particle behavior according to the internal phase change in the initial generation step according to the conventional system. FIG. 7 (b) shows the ice cream particle behavior according to the internal phase change in the initial generation step according to the embodiment of the present invention.

FIG. 7 (a) shows a case where ice cream is generated by rotating only at a high speed in the initial generation step and the post-discharge step according to the conventional method. In the case of generating ice cream as described above, The texture, ice quality and the amount of output per unit time continue to change. Therefore, the size of ice cream particles is not uniform. In addition, since the changing point of the rotation speed of the Daishag motor 109 is not based on the load measured by the Daishag motor 109, it is impossible to accurately change the rotation speed of the Daishag motor 109 according to the phase change, It is impossible to maintain the ice quality of the ice cream.

On the other hand, the ice cream is generated at high speed in the initial generating step and the post-ejecting step, respectively, and the rotation speed is changed at the point of time (phase change point) 7 (b), the relatively small particles generated in each of the first generation section (P1 in FIG. 5) and the fifth generation section (P9 in FIG. 5) Particles are grown at a relatively low speed in each of the second generation period (P3 in FIG. 5) and the sixth generation period (P11 in FIG. 5) Ice cream is formed while maintaining the size, and texture and shape formation can be ensured. That is, the ice cream particle size is made uniform.

As described above, in the six-stage ice cream production step control according to the embodiment of the present invention, the same load is measured with the same control point but different in frequency, and the deviation of the ice cream level in each stage is small, The control is performed at a relatively low speed to maintain a relatively uniform particle size, thereby improving the beam formation.

In the above description, the ice cream production step is described as six stages. However, the present invention is not limited to the six stages, and only the initial stage may be changed to the fifth stage or the second stage may be changed to the fifth stage. In another embodiment, the initial creation step or the post-projection step may be further subdivided into six or more steps.

Also, the control unit 121 can control the opening time of the dispensing opening 123, and control the amount of the generated ice cream to be discharged to the outside.

It is common for ice cream to be sold in certain containers at the time of sale, in which case a certain amount of ice cream is required to be delivered. However, ice ice (intensity) of ice cream is different depending on the stage of ice cream production, and the amount of ice cream to be output per unit time is not constant. 8 shows changes in the amount of ice cream discharged per unit time in the stage of generating ice cream.

As shown in FIG. 8, the amount of ice cream discharged per unit time is large immediately after the first speed (first speed) of ice cream. In the ice cream storing step (Break), the amount of ice cream per unit time is increased as the storage time is longer. That is, the amount of ice cream discharged per unit time is the most immediately before entering the ice cream holding step (Run). However, the amount of ice cream delivered per unit time is the smallest after the ice cream dispensing stage (Draw), and the amount of ice cream discharged per unit time is small even in the ice cream maintaining stage.

Immediately after the first ice cream producing step, the amount of soft ice cream, which is composed of solid, liquid and gas, is filled in the cylinder 107, and the amount of emission per unit time is increased. In the ice cream storing stage, the ice cream melts at the inner wall of the cylinder and the inner wall of the shocker cover, resulting in a high liquid ratio on the wall surface. Accordingly, the frictional force is reduced, and accordingly, the amount of ice cream discharged per unit time is the greatest.

On the other hand, after the ice cream dispensing step, the ratio of the liquid is increased by the freshly introduced raw liquid in proportion to the ice cream discharge amount, the liquid ratio in the cylinder 107 becomes high and the amount of discharge per unit initial amount is small. Similarly, in the ice-cream maintaining step, the liquid ratio in the cylinder becomes high, and the amount of the discharge per unit time becomes small.

It can be seen that the volume change of the undiluted solution is not observed when the ice cream is produced, and therefore the density change of the inner ice cream is not large. As a result, it is considered that the amount of ice cream per unit time is changed by the change of the ratio of the solid and the liquid in the ice cream, and the amount of ice cream per unit time is changed according to the viscosity of the ice cream.

The propulsive force of the ice cream is generated by the rotation of the Dasher bundle, and is proportional to the rotation number (RPM) of the Dasher. The surface force (frictional force) is generated at the inner wall of the cylinder or the inner wall of the dasher cover, that is, the interface between the flow path and the fluid, and is proportional to the viscosity. The volume force of the ice cream is generated inside the ice cream, and considering the characteristics of the ice cream (keeping the fluid behavior in the ice cream dispensing and maintaining the shape after the dispensing), the ice cream is a non-Newtonian fluid having a shear stress that is not directly proportional to the strain It is reasonable to interpret it as a shear stress model of an ideal plastic fluid. This is shown in Equation (2).

Figure pat00002

Here, τ yx represents the shear stress, τ y represents the minimum yield stress, η represents the apparent viscosity, and du / dy represents the rate slope, which represents the amount of the ice cream delivered per hour (strain).

The relationship between the shear stress τ and the strain du / dy is shown in FIG. 9, and the relationship between the apparent viscosity η and the strain du / dy is shown in FIG. As shown in Figs. 9 and 10, when the shear stress increases or the apparent viscosity increases, the strain increases.

The following facts can be seen from this. It can be seen that the shear stress is increased when the ice-cream-releasing resistance is large, which means that the viscosity is increased. It can be seen that the amount of ice cream per unit time will be increased accordingly. On the contrary, when the ice cream-releasing resistance is small, it can be seen that the shear stress is decreased and the viscosity is lowered. It can be seen that the amount of ice cream per unit time will be reduced accordingly. If the storage time of the ice cream is prolonged, it is understood that the frictional force is lowered and the amount of ice cream per unit time of discharge will increase.

In summary, if the force (= stress) required for the ejection of the ice cream increases, the strain rate of the ice cream increases, the amount of ice cream per unit time of discharge increases, and if the storage time of the ice cream becomes longer, the frictional force decreases, The amount of discharge per unit time is increased.

The dasher 107 is rotated using the Daishag motor 109, and the torque of the Daishag motor 109 is as shown in the equation (1).

As shown in Equation (1), if the current I of the Daisha motor 109 increases or the number of revolutions per unit time decreases, the force required to eject the ice cream increases. That is, when the current measured by the Daisha motor 109 before the icecream is high or the number of revolutions per unit time is small, the amount of ice cream per unit time is increased. On the contrary, when the current measured by the Daisha motor 109 before the icecream is low or the number of revolutions per unit time is large, the amount of ice cream discharged per unit time is decreased.

2, an embodiment 100 of an ice cream manufacturing apparatus according to the present invention includes an ice maker 100, which can dispense a predetermined amount of ice cream, 107, a Daisha motor 109, a Daisha motor load measuring unit 119, an ice cream storing time measuring unit (not shown) and a control unit 121.

The dasher 107 is located inside the cylinder 101 as described above, and stirs the liquid ice-cream stock solution and air introduced into the closed cylinder 107.

The Dasher motor 109 also rotates the bushers 107 as described above.

The Daishier motor load measuring means 119 can measure the current of the Daisha motor 109 or the number of revolutions per unit time by measuring the load of the Daisha motor 109 as described above.

The ice cream storing time measuring means (not shown) measures the elapsed time of the ice cream storing step (Break).

The controller 121 controls the dispensing time of the ice cream on the basis of the load of the stirrer motor 109 measured by the stirrer motor load measuring means 119. The dispensing time of the ice cream can be controlled by adjusting the opening time of the dispensing opening 123. [ To this end, the control unit 121 is set with the reference current or predetermined number of revolutions per unit time, in which a predetermined amount of ice cream is projected. The reference current or the number of revolutions per unit time per unit time may be set to one or more.

If the current measured by the Dascher motor load measuring means 119 is large or the number of revolutions per unit time is small, the amount of ice cream to be discharged per unit time is increased. On the other hand, if the current measured by the Daishier motor load measuring means 119 is small or the number of revolutions per unit time is large, the amount of ice cream discharged per unit time is reduced.

Therefore, the control unit 121 controls the ejection time of the ice cream to be reduced if the current measured by the Daishier motor load measuring unit 119 is larger than the reference current. For example, when the current measured by the Daishier motor load measuring unit 119 is large, the controller 121 controls the opening time of the discharge port 123 to be reduced so that a predetermined amount of ice cream can be discharged. On the contrary, if the current measured by the DSC motor load measuring means 119 is smaller than the reference current, the controller 121 increases the opening time of the dispensing opening 123 and controls the dispensing time of the ice cream to be increased.

Likewise, the control unit 121 controls the delivery time of the ice cream to be reduced when the rotation speed per unit time measured by the Daishier motor load measurement unit 119 is smaller than the reference rotation speed per unit time. For example, when the rotation speed per unit time measured by the Daishier motor load measuring unit 119 is small, the controller 121 controls the opening time of the discharge port 123 to be reduced so that a predetermined amount of ice cream can be discharged. On the contrary, if the rotation speed per unit time measured by the Mohsen motor load measuring unit 119 is larger than the reference rotation speed per unit time, the controller 121 increases the opening time of the discharge port 123 and controls the discharge time of the ice cream to be increased.

The control unit 121 may control the dispensing time of the ice cream based on the elapsed time of the storing step of the ice cream measured by the ice cream storing time measuring unit. For this purpose, the control section 121 sets the reference storage time of the ice cream in advance. The reference retention time may be set to one, or several reference retention times may be set.

As described above, when the storage time of the ice cream is prolonged, the ice cream melts on the inner wall of the cylinder and the inner wall of the washer, so that the frictional force decreases and the amount of ice cream discharged per unit time increases. Accordingly, when the storage time of the ice cream measured by the ice cream storage time measuring means reaches the reference storage time, the control unit 121 shortens the opening time of the dispensing opening 123 and controls the dispensing time of the ice cream to be reduced.

11 is a flowchart illustrating an ice cream dispensing method according to an embodiment of the present invention.

As described above, the ice cream is produced through the first generation step (first speed) in which the liquid ice-cream stock solution is produced as a solid ice-cream. And a storage step (Break) for storing the solidified ice cream and a maintenance step (Run) in which the solidified ice cream is mixed with the partially melted ice cream in the cylinder to regenerate the ice cream. The ejection of the ice cream occurs while the ice cream is stored and maintained. After the ice cream is delivered, the original liquid of the ice cream is injected as much as the amount of the delivered ice cream, and the remaining ice cream and the freshly introduced ice cream stock solution and air are mixed to regenerate the ice cream. The step of regenerating the ice cream after the ice cream is dispensed is an after draw as described above. When the post-dispensing step is completed, the storing step and the maintaining step are repeated again. The ice cream can be delivered to the outside not only in the storage step and the maintenance step but also in the post-discharge step.

Referring to FIG. 11, when the ice cream is discharged while the ice cream is stored and maintained (S201), the current or the number of rotations per unit time of the Daisha motor 109 is measured (S203). Then, the measured current or the number of revolutions per unit time is compared with the reference current or the reference number of revolutions per unit time (S205). If the measured current is larger than the reference current or the measured revolutions per unit time is smaller than the reference revolutions per unit time, the amount of ice cream delivered per unit time is large, so that the dispensing time of the ice cream is reduced and a certain amount of ice cream is discharged (S207). On the contrary, if the measured current is smaller than the reference current, or if the measured number of revolutions per unit time is larger than the reference number of revolutions per unit time, the amount of the ice cream per unit time is small so that the amount of ice cream can be projected (S209).

Although not shown in FIG. 11, when the elapsed time of the storing stage of the ice cream reaches the reference storage time, the amount of the ice cream per unit time of discharge is increased, so that the dispensing time of the ice cream is reduced and a certain amount of ice cream can be discharged. This may be performed separately from steps S207 and S209, or may be performed when performing steps S207 and S209. For example, when the current measured by the Taescher motor 109 is larger than the reference current, and the ice-cream storage time reaches the reference storage time, in step S207, the ice-cream delivery time is further reduced, . Likewise, if the number of revolutions per unit time measured by the Daisha motor 109 is larger than the reference number of revolutions per unit time and the ice-cream storage time is significantly smaller than the reference storage time, the operation time of the ice- Allow a certain amount of ice cream to be dispensed.

As described above, by regulating the time of dispensing the ice cream from the load (the current or the number of revolutions per unit time) measured by the Daishag motor 109 and the storage time of the ice cream, the discharge amount of the ice cream can be controlled to be constant.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the particular embodiments set forth herein. It will be understood by those skilled in the art that various changes may be made and equivalents may be resorted to without departing from the scope of the appended claims.
