DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing soymilk, and more particularly to an improvement in the arrangement of a cooking pot and a pressing machine in the apparatus, and belongs to the field of soymilk production technology.

[0002]

2. Description of the Related Art For example, soymilk, which is a raw material for tofu, is soaked in water to swell soybeans, and the resulting mixture is heated and agitated, and the resulting gel-like material called "nigo" is pressed. Manufactured. Therefore, in general, a soy milk production apparatus is provided with a cooking pot for producing boiled go and a pressing machine for extracting soy milk from the boiled go. For example, in a soymilk production apparatus disclosed in Japanese Patent Application Laid-Open No. 8-214815, a cooking pot is arranged above a pressing machine. On the other hand, in the soymilk production apparatus disclosed in Japanese Utility Model Registration No. 3004561, a pressing machine is arranged above the cooking pot. In each case, a pipe is provided between the cooking pot and the pressing machine, and the boiled gou produced in the cooking pot is supplied to the pressing machine through the pipe.

[0003] Conventionally, as a pressing machine, a screw in which a boiled go is pressurized by the rotation of a spiral blade is provided in a cylindrical jacket, and a press is provided in a cylindrical shape around the screw. A screw press type having a screen for extracting soy milk from boiled go is widely used. In this case, as disclosed in the above publication, a supply port for boiled go is provided at one end of the jacket, and a discharge port for soymilk and okara, which is a pressed residue, are provided at the other end. Is supplied to the pressing machine from the supply port, and then separated into soymilk and okara while being transported by a screw in the jacket, and each is discharged to the outside from each discharge port.

[0004]

However, when the cooking pot and the pressing machine are arranged vertically as in the apparatus disclosed in the above-mentioned publication, the floor installation area is reduced but the height of the apparatus is increased. Conversely, when these are arranged side by side, the width of the device becomes large. Therefore, in any case, the size of the soymilk producing apparatus cannot be reduced as a whole.

[0005] On the other hand, boiled gou contains a large amount of solid components, and when cooled, viscosity increases and yuba is generated. Therefore, if the boiled gou taken out of the cooking pot is not sufficiently kept warm during the pressing, a high load is applied to the rotation of the screw, so that the pressing process becomes difficult or the screen is clogged. The above-mentioned publication does not disclose such a heat retaining means, and if a device for keeping the temperature of the boiled squeezed gou is added separately, the whole soymilk production device becomes even larger.

In view of the above situation, the present invention improves the arrangement of the cooking pot and the pressing machine to reduce the size of the soymilk production apparatus, and eliminates the need to provide a dedicated heat retaining device for the boiled gou during pressing. It is an object to keep the temperature sufficiently. Hereinafter, the present invention will be described in detail including other problems.

[0007]

Means for Solving the Problems In order to solve the above-mentioned problems, in a soymilk production apparatus according to the present invention, soybeans and water are heated and agitated to squeeze the boiled gou into a boiler for producing a boiled gou. A squeezing machine for squeezing soy milk is arranged. In particular, the pressing machine is arranged in the cooking pot in a portion between the supply port of the boiled go and the discharge port of the soy milk, that is, in a range where the boiled go moves during the pressing process.

[0008] Since the cooking pot and the pressing machine are not separately arranged, but the pressing machine is housed in the cooking pot and they are integrated, the whole soymilk production apparatus becomes compact,
Installation space is small. In addition, since the cooking pot functions as a heat retaining device of the pressing machine, it is possible to smoothly perform the pressing process without separately providing a dedicated heat retaining device.

According to a more specific aspect of the present invention,
The pressing machine is a screw press type having a screw for pressurizing the boiled gou, and a screen for straining soy milk from the pressurized boiled gou, in a cylindrical jacket, and a range in which the screen is installed. , A pressing machine is accommodated and arranged in the cooking pot. The boiled gou is cooled and the viscosity is increased, and it is possible to avoid that a high load is applied to the rotation of the screw to make the pressing process difficult, and in particular, it is possible to effectively prevent clogging due to sticking of the yuba on the screen. You.

According to another more specific aspect of the present invention,
Around the squeezing machine, the stirring blades for the boiled go inside the boiler are rotatably provided at a portion arranged in the boiler. The boiling pot is provided with rotating blades as a means for crushing soybeans and stirring the boiled go. Rather than disposing the stirring blades and the pressing machine separately in the cooking pot, the stirring blades are provided on the outer periphery of the pressing machine and integrated with each other. The capacity of the hook does not decrease.

Hereinafter, the present invention will be described in more detail through embodiments of the present invention.

With such a configuration, the stirring blades 19... 19 are always driven to rotate when the drive motor 50 is operated, whereas the compression screw 35 is driven by the spiral blades 33 in accordance with the rotation direction of the drive motor output shaft 50a. It is selectively driven to rotate only in the forward direction.

A cylindrical screen 32 is stretched around the pressing screw 35 so as to surround the screw 35. The screen 32 has an end on the supply port 37 side attached to the inner surface of the jacket 31 and an end on the discharge port 40 side attached to the inner surface of the left bearing unit 41. Although not shown, an infinite number of fine holes are formed in the peripheral surface of the screen 32, and the inner surface thereof is almost in contact with the spiral blade 33 of the screw 35 and the scrapers 34.

At this time, the spiral blade 33 gradually decreases in blade pitch and blade width from the supply port 37 side to the discharge port 40 side, and accordingly, the cylindrical screen 32 moves in the same direction. It has a tapered shape.

When the left bearing unit 41 is rotated via screwing with the jacket 31, the end of the unit 41 or the cylindrical screen 32 on the discharge port 40 side moves in the longitudinal direction with respect to the jacket 31. I do. Accordingly, the gap between the screen 32 and the screw 35 can be adjusted.

As shown in FIG. 3 in particular, the left bearing unit 41 has a space inside and outside the jacket 31, more specifically, a space surrounded by a tapered cylindrical screen 32 inside the jacket 31. A communication passage 60 is provided for communicating between the outside and the outside, and serves as an outlet for okara, which is a compressed residue. The outlet member 60 has a lid member 61.

And a return spring 64 is interposed therebetween. The screw shaft 62 into which the receiving plate 63 is inserted is screwed with a nut 65, and by rotating the nut 65, the distance between the lid member 61 and the receiving plate 63, that is, the compression length of the spring 64 is changed, so that the lid member 61 is compressed. The pressing force against the discharge port 60 is adjusted.

An L-shaped link 66 is attached to the receiving plate 63.
A link 67, an operation lever 68 to which these links 66, 67 are connected, and a left protruding end 31a of the jacket 31.

Further, a chute 71 for receiving the okara dropped and discharged from the discharge port 60 is provided at the left protruding end 31 a of the jacket 31.

Next, an example of a specific soymilk producing operation of the soymilk producing apparatus 1 will be described.

First, soybeans and water are charged into a cooking pot 10 in a predetermined amount and at a predetermined ratio from a raw material input port 12, and are stirred by a stirrer 14 for a predetermined time while being heated by a heater 13, crushed and mixed. To produce boiled go. At this time, it is preferable to rotate the stirring blades 19... 19 so as to be opposed to the high-temperature steam ejection direction of the heater 13.

Next, the heater 13 and the stirrer 14 are stopped, and the pressure pump 38 is operated. The generated boiled go is introduced into the jacket 31 from the boiled supply port 37 of the pressing machine 30 through the pipe 36.

The squeezing screw 35 is driven, and the boiled go is transferred to the discharge ports 40 and 60 by the spiral blade 33. The boiled go moves in the longitudinal direction in the jacket 31 so as to cross the inside of the boiler 10. While passing through the jacket 31, the boiled gou is gradually squeezed by the reduced pitch and width of the spiral blades 33 and the tapered shape of the screen 32, and separated into soymilk and okara.

The separated soy milk is drawn out from the inside of the screen 32, fills the outer space of the screen in the jacket 31, and is taken out from the soy milk outlet 40 of the pressing machine 30 through the pipe 39. On the other hand, okara is a spiral blade 33
And is discharged from the discharge port 60 of the left bearing unit 41 and falls onto the chute 71. At the time of discharging, the okara is covered with the lid 61 against the urging force of the spring 64.
Press to open. Therefore, by adjusting the pressing force of the lid 61 against the outlet 60, the pressing pressure of the boiled go is adjusted.

While the squeezing machine 30 is performing such squeezing work, the cooker 10 continues to produce the next boiled gou. That is, when all of the previously produced boiled gou has been supplied to the pressing machine 30, the pump 38 is stopped, soybeans and water are newly charged into the boiler 10, and heating by the heater 13 and The stirring by the stirrer 14 is performed. Then, when the boiled go is formed, the pump 38 is reactivated,
The generated boiled go is sent to the pressing machine 30.

At this time, if the same quality soymilk is to be produced, the first boiled go and the next boiled go may be mixed in the pressing machine 30. Therefore, regardless of the progress of the previous boiled gou pressing work, in other words, regardless of whether or not the previous boiled gou remains in the jacket 31, the next boiled gou is immediately squeezed at the time of its generation. Machine 30. On the other hand, when the quality of the previous boiled gou is different, even if the next boiled gou is produced, the boiled gou is kept waiting in the boiler 10 until all of the previous boiled gou is processed by the pressing machine 30. .

As described above, in the soymilk production apparatus 1 according to this embodiment, the soybean milk and the soybean milk are heated and agitated, and the soymilk is squeezed into the cooking pot 10 for producing the soybean milk. Machine 30, and in particular, the pressing machine 30
7 is disposed in the cooking pot 10 in a portion between the soymilk discharge port 40, that is, the range in which the boiled go moves during the squeezing process. Therefore, the cooking pot 10 and the pressing machine 30
And the squeezing machine 30
Are stored in the cooking pot 10 and they are integrated, so that the whole soymilk producing apparatus 1 is compact and the installation space is small. In addition, the cooking pot 10 is a pressing machine 30.
, And the squeezing process can smoothly proceed without separately providing a dedicated heat retaining device.

Further, since the pressing machine 30 is accommodated in the cooking pot 10 within the installation range of the screen 32, the boiling water is cooled and the viscosity becomes high, and a high load is applied to the rotation of the screw 35 to perform the pressing process. The difficulty can be avoided, and in particular, the clogging caused by the sticking of the yuba on the screen 32 can be effectively avoided. The scrapers 34... 34 physically scrape the high-viscosity adhesive adhered to the inner surface on the upstream side of the screen 32.

Furthermore, in the arrangement portion in the cooking pot 10, the stirring blades 19 ... 19 are rotatably provided around the jacket 31 of the pressing machine 30, so that the stirring machine 14 and the pressing machine 30 are boiled. The internal configuration of the cooking pot 10 is simpler than in the case where the cooking pots 10 are separately arranged, and the capacity of the cooking pot 10 is secured.

[0035]

As described above, according to the present invention, the arrangement of the cooking pot and the pressing machine is improved, and as a result, the soymilk production apparatus becomes compact, the installation space is small, and the inside of the cooking pot is reduced. Using the temperature, the boiled squeezed go can be sufficiently kept warm, and the squeezing process is performed smoothly.

The present invention can be widely and suitably used not only in the production of soymilk as a beverage and soymilk as a raw material for tofu, but also in the general food manufacturing industry involving the pressing of a gel-like substance under heating.
