Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soymilk producing apparatus which can easily produce soymilk in a short time at home. 2. Description of the Related Art Conventionally, as this type of soymilk producing apparatus, for example, one described in Japanese Patent Application Laid-Open No. 2001-299260 is known. This involves placing a container on a heater provided at the base of the main body, storing water in the container and holding a basket containing soybeans in a suspended state, and driving a crushing blade in the basket by an electric motor. Then, the soybean is crushed, the water-soluble component of the soybean is eluted in water, the water-insoluble component is dispersed in water, and the soybean slag is retained in the basket by the filter. Then, the user takes out the basket from the container and separates the soy milk from the soybean scum in the basket to obtain the soy milk. [0003] In these soy milk making machines, since it takes time until the soy milk is completed, the user is less likely to stick to the soy milk making machine, and is performing other work or taking a break during soy milk making. It seems that there are many cases. However, in these conventional soymilk making devices, when the soymilk making process is completed, the electric motor and the heater are turned off, so that the temperature of the soymilk in the container gradually decreases and the viscosity of the soymilk gradually increases. It will go. And, as mentioned above, since the user is not necessarily at the side of the soymilk production device immediately after the end of the soymilk production process, by leaving the basket in the state after the end of the soymilk production process and letting it cool,
There is a possibility that the viscosity of the soymilk may be increased, and as a result, it becomes difficult to separate the soymilk from the mixture of the high-viscosity soymilk and soybean slag in the basket, and it takes time to use the soybean slag as okara. There was a fear that. [0004] It is an object of the present invention to solve the above problems and to provide a soymilk production device capable of easily separating soymilk and soybean slag. [0005] The soymilk producing apparatus of the present invention comprises:
A main body having an electric motor provided therein, a container detachably provided to the main body, a basket held in the container and communicating with the inside and outside via a filter, and the electric motor provided in the basket and provided with the electric motor. A crushing blade driven by a heater, a heater for heating the container, and a control circuit for controlling the energization of the electric motor and the heater, wherein the control circuit controls the energization of the heater and / or the electric motor. Thus, after the soymilk producing step of producing the soymilk by dissolving and dispersing the soybean component in water, a warming step of keeping the soymilk produced in this step for a predetermined time is executed. According to the present invention, in the soymilk production process, the heater and / or the electric motor are controlled to be energized in the soymilk production process, so that the soybeans crushed by the crushing blade in the basket are heated. The soy components elute and disperse in the water in the container. Then, after the soymilk production process is completed, the viscosity of the soymilk is kept low by keeping the soymilk warm in the warming process. Hereinafter, embodiments of the present invention will be described.
A description will be given with reference to FIGS. Reference numeral 1 denotes a main body. The main body 1 includes a base 2, a standing portion 3 erected from the base 2, and a head 4 attached to and supported by the standing portion 3.
And are substantially U-shaped on the side. A heater 5 is attached to the base 2, and the heater 5 is formed by casting a sheath heater 7 into a heater base 6 made of aluminum die-cast. In addition, the upper surface of the heater base 6 is formed in a convex spherical shape of about 100φ to 1000φ. The movable part 9 is urged upward by an elastic member such as a spring (not shown) inside the head 4.
The movable portion 9 is mounted movably in the vertical direction, and a short cylindrical protection frame 10 is attached to the lower end of the movable portion. And
An electric motor is mounted on the movable part 9 so that the drive shaft is substantially vertical.
11 is installed. Above the head 4, there is provided a switch cover 12 which comes into contact with the movable portion 9 and is rotatable in the horizontal direction. Further, a connecting body 14 constituting a coupling 13 is attached to the lower end of the drive shaft of the electric motor 11 so as to be exposed below the movable part 9 and inside the protection frame 10. [0008] Between the base 2 and the head 4 of the main body 1,
A cylindrical container 15 with a bottom and an open top is detachably arranged. The container 15 is made of stainless steel, and a heat equalizing layer 16 is formed by welding an aluminum plate to the bottom outer surface, and the lower surface of the heat equalizing layer 16 is in close contact with the upper surface of the heater base 6. 100
It is formed in a concave spherical shape of about φ to 1000φ. The provision of the heat equalizing layer 16 in this manner is because the container 15 is formed by drawing stainless steel, the processing accuracy is difficult to obtain, and when the container 15 is formed only of stainless steel,
This is because there is a possibility that the area in contact with the heater base 6 is reduced. When the bottom of the stainless steel container 15 comes into contact with the heater base 6 in a narrow range,
Although there is a risk that only the portion in contact with the heater base 6 becomes hot, the heat equalizing layer 16 is formed,
16 so that the lower surface of 16 is in close contact with the upper surface of heater base 6.
By forming a concave spherical shape of about 0φ to 1000φ, heat from the heater 5 is transmitted to the heat equalizing layer 16 on an average and further to the bottom of the container 15 on an average. A grip 17 is attached to a side surface of the container 15, and a container lid 18 is detachably attached to an upper portion of the container 15. The container lid 18 has a concave portion 19 formed substantially at the center, and a through hole 20 formed at the center of the concave portion. The recess 19 is formed slightly larger in diameter than the protection frame 10. A pair of sensor electrodes 21 and 22 are attached to the lower side of the container lid 18. Below the through hole 20, a basket 23 is detachably mounted. The basket 23 includes a hanging part 24 and a housing part 25 having an open side and a bottom.
And a housing lid 26 attached to the lower opening of the housing 25. A driven shaft 27 is rotatably attached to the hanging portion 24. This driven shaft
At the upper end of 27, the coupling body 14
A connecting body 28 constituting 13 is attached. And
The connecting body 28 is exposed from the through hole 19 when the basket 23 is attached to the container lid 18. Further, the lower end of the driven shaft 27 extends to a lower portion in the housing portion 25,
A crushing blade 29 is detachably attached to the lower end of the driven shaft 27. The crushing blade 29 has a tip end extending in a direction delayed with respect to the rotation direction, and an inclined portion 29a having a rear portion inclined upward with respect to the rotation direction at an end thereof. The housing portion 25 is formed in a slightly flat and substantially short cylindrical shape having a slightly wide lower portion and an inner diameter of about 1.5 times the inner height. The inner size of the storage section 25 is the same as the storage section 25 in which the necessary amount of soybean S is stored in the container 15 in which the required amount of water is stored for producing a predetermined amount of soymilk.
When soybeans are put, even the highest one of the soybeans S is immersed in water. Desirably, all the soybeans S are formed with a diameter sufficient to be lower than the water surface W. And
A mesh filter 30 is detachably attached to the side surface of the housing portion 25. Further, the mesh filter 31 is also provided on the housing lid 26 attached below the housing 25.
Is formed. The housing lid 26 is engaged with the housing 25 by rotating in the axial direction, or the housing 25 is rotated in the axial direction.
Is formed so as to be disengaged from the connector. A slanted surface 32 having a higher outer peripheral side is formed around the filter 31 on the inner side 26a of the housing lid 26, and a short rib-like shape is formed on the outer 26b of the housing lid 26. A plurality of projections 33 are formed radially. Reference numeral 34 denotes a control circuit for controlling the energization of the electric motor 11 and the heater 5. Next, the operation of the present invention will be described. First, a required amount of dried soybean S is immersed in water for 5 to 7 hours in advance so that the soybean S absorbs water. At this time, this soybean S
It is desirable to soak it in a container (ball or the like) different from 15 and basket 23. And soybean S soaked in this water
Into a basket 23 equipped with a crushing blade 29 and a filter 30.
And the opening is closed by the housing cover 26. Then, the basket 23 is attached to the container lid 18, and stored in the container 15 storing a required amount of water. Then, the container 15 is inserted between the base 2 and the head 4 of the main body 1 and placed on the heater 5. When the switch cover 12 is further rotated clockwise by 180 degrees, the movable unit 9 and the electric motor 11 are moved downward by a lifting mechanism (not shown). The connecting body 14 attached to the lower end of the shaft of the electric motor 11
Meshes with the connector 28 attached to the upper end of the
The lower end of 10 is in contact with the concave portion 19 of the container lid 18, and these protective frames 10
And the container lid 18 cover the coupling 13. at the same time,
A switch (not shown) is closed, and the control circuit 34 starts energization control of the heater 5 and the electric motor 11. The operation of the heater 5, the electric motor 11, and the crushing blade 29 will be described with reference to FIG. In addition, the time of each step described below is an example, and can be appropriately changed. First, when the switch (not shown) is closed by rotating the switch cover 12, a preheating step is started. In this preheating step, the heater 5 is continuously energized. by this,
The water in the container 15 and the soybean S in the basket 23 are heated. In this step, the electric motor 11 is not energized. After a 7 minute preheating step, the process proceeds to a pulverizing step. In the pulverizing step, the heater 5 is continuously energized, and the electric motor 11 is energized so as to repeat the energization stop period of 10 seconds and the energization period of 20 seconds. That is, the electric motor 11 rotates the crushing blade 29 intermittently and periodically. As a result, the water in the container 15 is warmed, and
The soybean S stored in the inside is crushed by the crushing blade 29. The movement of soybean S and water in the storage section 25 will be described in detail. Since all of the soybeans S are immersed in water in the storage section 25, these soybeans S are generated by the water flow caused by the rotation of the crushing blade 29. It is possible to circulate inside. Then, due to the centrifugal force due to the rotation of the crushing blade 29, the water level on the outer peripheral side in the storage unit 25 rises and reaches the ceiling 25a, and the water flow heading toward the outer peripheral side by the centrifugal force at the lower part of the storage unit 25 is stored. Ascending along the inclined surface 32 formed on the inner side 26a of the lid 26, and furthermore, the inclined portion 29a is formed on the crushing blade 29, so that an upward water flow is generated on the outer peripheral side in the accommodating portion 25. I do. And these water flows are
The soybean S mixed in the water stream is repeatedly crushed by frequent collision with the crushing blade 29 because it is circulated by quickly changing its direction upon hitting a, returning to the center side of the storage portion 25 and descending. For this reason, a large amount of soybean S can be ground without leaving a large amount in the storage section 25, and the concentration of soybean component in soymilk can be increased in a short time. And during this crushing process,
The soybean S is crushed and stirred in the storage section 25. As a result, the water-soluble soybean component is eluted into the warm water, and the water-insoluble soybean component is also dispersed in the warm water. Stays in the accommodation section 25. At this time, since components such as saponin are dissolved in the soy milk being manufactured, bubbles easily occur due to turbulence or the like, but as described above, the water flow directed to the outer peripheral side at the lower portion of the storage portion 25 is along the inclined surface 32. As it rises smoothly, turbulence is less likely to occur, which suppresses foaming of the soy milk during production. During the pulverizing process, the soybean S in the basket 23 is pulverized while the water in the container 15 is heated by the heater 5. At this time, when the soybean S is pulverized in a state where the temperature around the soybean S is high, the soybean S tends to be pulverized into fine particles. However, during the pulverization process, the water temperature rises only up to about 50 ° C.
The pulverized soybean S contains fewer unnecessarily fine particles, so that the soybean S passes through the filters 30 and 31 and passes through the storage section 25.
Little soy particles are emitted outside. After a 4-minute pulverizing step, the process proceeds to a heating step. In this heating step, the heater 5 is intermittently and periodically energized, and the energization of the electric motor 11 is stopped. Note that the heater 5 will be energized intermittently and periodically thereafter until the soymilk production process ends. During this time, the water-soluble component is eluted from the soybean S, and the water-insoluble component continues to be dispersed. Further, by continuing the heating in this manner, the fresh smell disappears from the soymilk being manufactured.
The average temperature of the soymilk during the production is about 80 to 90 ° C., but the water-insoluble components and soybean particles are slightly settled near the bottom in the container 15, so that the soymilk near the bottom is partially However, when bubbles come into contact with both of the sensor electrodes 21 and 22 at the same time and the two sensor electrodes 21 and 22 are electrically connected to each other, the power supply to the heater 5 is stopped and the soymilk is removed. Spills and burning of soybean particles are prevented. Further, since the heat equalizing layer 16 that can be in close contact with the upper surface of the heater base 6 is formed on the outer bottom of the container 15, the heat of the heater 5 is transmitted to the heat equalizing layer 16 on an average and the inside of the container 15 Since it is transmitted to the bottom on average, the inner bottom of the container 15 does not become extremely hot locally,
The phenomenon that non-water-soluble components and soybean particles are scorched is prevented. After a heating step of 15 minutes, the process moves to a stirring step. In this stirring step, as described above, the heater 5
Are intermittently and periodically energized, and the electric motor 11 is also intermittently and periodically energized, so that the crushing blade 29 intermittently and periodically rotates. In this step, the energizing period of the electric motor 11 is shorter than the energizing period of the electric motor 11 in the pulverizing step,
The power supply period of 5 seconds and the power supply stop period of 55 seconds are alternately repeated. At this time, the soybean S crushed in the storage section 25 is stirred, so that the high-temperature soymilk outside the storage section 25 is filtered.
The soybean component is further eluted and dispersed in the basket 23 while passing through the filters 30 and 31, and is then discharged out of the basket 23 through the filters 30 and 31. For this reason, the soybean component is more contained in the soymilk. In addition, among the soybeans S crushed in the basket 23, those having a small particle size are diffused into the container 15 through the eyes of the filters 30 and 31, but by rotating the crushing blade 29 during heating. Not only the short time before the end of the soymilk production process, but also the grinding blade
Due to the rotation of 29, a water flow is generated in the container 15, so that the water-insoluble components and soy particles hardly settle, and even if settled slightly, it is a short time. And the like is less likely to be scorched. And
Four minutes after the start of the stirring step, the power supply to the electric motor 11 is stopped, and the soymilk production step including the preheating step, the crushing step, the heating step, and the stirring step ends. After the end of the soymilk production process, the process proceeds to the heat retention process. In this heat retaining step, the power supply time to the heater 5 is shorter than the power supply time in the heating step and the stirring step, and the power supply for 8 seconds and the power supply stop for 52 seconds are alternately repeated for 20 minutes. As a result, the soymilk in the container 15 and the basket 23 is kept at 80 ° C. or higher. When the soymilk is taken out, when the switch cover 12 is rotated counterclockwise by 180 degrees, the movable portion 9 and the electric motor 11 are moved upward by a lifting mechanism (not shown), and the engagement of the coupling 13 is released. With protective frame 10
Is separated from the concave portion 19 of the container lid 18, and at the same time, a switch (not shown) is opened. Then, the container 15 is taken out from between the base 2 and the head 4 of the main body 1 and the basket 23 is removed from the container 15 to complete the soymilk. At this time, by keeping the soymilk warm, the user can drink warm soymilk without reheating the soymilk during the warming process. Then, when the basket 23 is placed on a saucer or the like such that the housing lid 26 faces downward,
Soymilk is separated from the mixture of soybean slag (okara) and soymilk in the storage section 25 and flows out. At this time, if the housing portion lid 26 is in contact with a tray or the like, the gravity is applied, so that the filter 31 from which the soy milk is most likely to flow out is closed. Since the projections 33 are formed on the lid 26, the storage portion 25 is floated from the tray by the amount of the projections 33.
The state is also likely to flow out of the filter 31 provided in the filter. For this reason, the soy milk flows out of the storage section 25 through the filters 30 and 31 satisfactorily. The soybean slag remaining in the storage section 25 is removed and discharged by rotating the storage section cover 26 around the axis. At this time, since the diameter of the housing portion 25 is large, it is difficult for a woman with a small hand to grasp the housing portion lid 26, but a rib-shaped protrusion is formed on the outer side 26b of the housing portion lid 26.
Since the projection 33 is formed, the user can hook the projection 33 to rotate the housing lid 26. Further, the basket 23 from which the soybean slag has been discharged can be easily cleaned by removing the crushing blade 29 and the filter 30. By the way, the viscosity of soymilk increases when it cools. Therefore, if the soymilk cools while the basket 23 is kept in the container 15, it is difficult for the soymilk to be separated from the soybean scum in the storage portion 25 when the basket 23 is taken out of the container 15. This is because the soybean scum attached to the inside of the filters 30 and 31 of the basket 23 makes it difficult for soy milk having a high viscosity to pass through the filters 30 and 31 and the soybean scum. However, as described above, during the warming process, the soy milk is kept warm,
Since the viscosity is kept low, soy milk is relatively easily separated from the soybean scum in the basket 23 when the basket 23 is taken out from the container 15. For this reason, if you come back to take out soy milk at the end of the soy milk production process, even if the return is somewhat delayed, the viscosity is kept low because it is in the heat retention process, soy milk and soy slag are The user does not need to be on hand with the soymilk making machine because it is relatively easy to separate. As described above, according to the present invention, the control circuit 34 is provided inside the main body 1 in the soymilk production process,
Rotating the motor 11 and the container attached to the body 1
After driving and controlling the heater 5 for heating 15, the soybean is crushed and agitated, and the components of the soybean are eluted and dispersed in water in the container 15 to produce soymilk. By keeping the soymilk in the container 15 warm for a predetermined period of time, the viscosity of the soymilk is kept low,
When taking out 23, the soymilk and the soybean slag can be relatively easily separated, so that the user does not need to cut off the soymilk producing apparatus. The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the above embodiment, the heat retention step is for 20 minutes, but can be appropriately changed within a range that does not impair the taste of soymilk. Further, another step may be inserted between the soymilk production step and the heat retaining step. According to the present invention, there is provided a soymilk producing apparatus comprising: a main body having an electric motor therein; a container detachably provided to the main body; a container held in the container and a filter. A soymilk production device comprising a basket with which the inside and outside communicate, a crushing blade provided in the basket and driven by the electric motor, a heater for heating the container, and a control circuit for controlling energization of the electric motor and the heater. After the soymilk production step of producing soymilk by dissolving and dispersing soybean components in water by controlling the energization of the heater and / or electric motor by the control circuit, the soymilk produced in this step is kept warm for a predetermined time. After the soymilk production process is completed, the temperature of the soymilk is kept low by keeping the soymilk warm in the heat retention process. Therefore, when removing the basket from the container, the soybean slag and the soymilk in the basket can be relatively easily separated.
