Description

The present invention relates to a stirrer that can be used for extraction or emulsification, and more particularly, for example, containing an animal raw material (eg, deer horn powder) or a vegetable raw material (eg, carrot, wolfberry, bitter gourd, or chlorophyll) A stirring device that can be used for extraction or emulsification for producing foods, cosmetics, or fragrances.

Chlorophyll, also called chlorophyll, is a green pigment that is present on the chloroplast substrate in plant chloroplast cells, for example with carotene, lutein, and xanthophylls. Since chlorophyll has, for example, an action of recovering skin diseases and burns, and an action of preventing malodor, this chlorophyll is processed into a drink, powder or tablet and used as a health food.
Among them, beverages that are drunk as health foods conventionally wash the leaves and stems of plants, and if necessary, for example, crush them into small pieces using a mechanical crushing means of a mixer or a juicer. It was manufactured by squeezing the stem. However, since chlorophyll is present in the hard cell membrane of plants, many chlorophylls could not be extracted by this method. For this reason, the chlorophyll is not sufficiently contained in the beverage produced by this method, and the beverage does not have the above-described effects.

Therefore, Patent Document 1 has two tanks and an ultrasonic vibrator provided between the two tanks and can be used for extraction or emulsification (manufacture of a health drink containing chlorophyll). Apparatus).
This stirrer mixes and mixes chlorophyll and water containing fats and oils with a stirring blade in one tank, and moves to the other tank while carrying out ultrasonic dispersion treatment in the middle of transfer by piping. In this device, chlorophyll and water are dispersed and mixed for emulsification treatment by repeatedly performing the operation of stirring and mixing, and transferring to one tank while performing ultrasonic dispersion treatment in the middle of transfer through another pipe.

JP 2004-57105 A (FIG. 3)

However, the conventional stirring device still has the following problems to be solved.
Since the above-described stirring apparatus has a complicated apparatus configuration, for example, chlorophyll-containing substances (fats) are likely to stay in tanks, piping, and stirring blades, and are difficult to stick and remove. For this reason, the sticking thing may rot by contact with water and may contaminate the product manufactured by the stirring device.
In addition, the sticky one cannot be easily removed even if, for example, a commercially available cleaning agent is used. As described above, when a cleaning agent is used, the cleaning agent easily adheres to the chlorophyll-containing material, and there is a possibility that an odor may adhere to the manufactured product.

The present invention has been made in view of such circumstances, and there is no stagnation of raw materials, the adhesion of raw materials can be suppressed and further prevented, it is hygienic and easy to clean, and can be used for extraction or emulsification with high processing efficiency. An object is to provide a stirring device.

The stirrer according to the present invention that meets the object is a stirrer that can be used for extraction or emulsification,
A hollow short tube group in which cylindrical hollow short tubes each provided with a raw material inlet at one end and a raw material outlet at the other end are connected in series, parallel, or series-parallel, and The inflow port is directed substantially tangential to the inner wall surface of the hollow short tube, and in use, the raw material flowing from the inflow port into the hollow short tube flows along the inner wall surface of the hollow short tube. Swirling to generate a swirling flow of the raw material in the hollow short tube.
Here, the hollow short tube that generates the swirling flow of the raw material inside is different from the conventionally used tube in which a spiral guide member is inserted inside, and nothing is inserted in the inside. Instead, the raw material flows in the direction of the tangential line of the hollow short tube (centrifugal force), and the raw material is swung along the inner wall surface of the hollow short tube to form a swirling flow of the raw material.

The stirrer of the present invention includes a raw material from an inflow port which is connected in series, in parallel, or in series-parallel to form a hollow short tube group in a cylindrical hollow short tube, which is directed substantially tangential to the inner wall surface. The material is swirled along the inner wall surface of the hollow short tube, so that a swirling flow of the material can be generated in the hollow short tube without arranging a spiral guide member as in the prior art. Can do. Thus, the apparatus configuration can be simplified, there is no stagnation of the raw material, the adhesion of the raw material can be suppressed and further prevented as compared with the prior art, and a hygienic and easy to clean stirring device can be provided.

Here, when the liquid inlet of the hollow short tube group is connected to the liquid outlet of the hollow short tube group via a pump and a connecting pipe connected thereto, a circulation path of the raw material is formed in the stirring device. Therefore, for example, the apparatus configuration can be made compact, and a space-saving and economical apparatus can be provided.
In addition, when an ultrasonic vibrator is provided in the hollow short tube group, and the ultrasonic vibrator is provided in any one or more of the hollow short tubes, between the adjacent hollow short tubes, and the connecting pipes. Since the raw material can be continuously irradiated with ultrasonic waves at a constant speed without retaining the raw material, the time for ultrasonic treatment can be shortened, and the production time of the product can be shortened.

When the outflow port is made substantially coincident with the inner wall surface of the hollow short tube so that the raw material swirling in the hollow short tube flows out while swirling, for example, the outflow port with respect to the hollow short tube Compared with the case where it is provided in the vertical direction, the outflow of the raw material from the hollow short tube can be carried out smoothly. Thereby, since the retention location of a raw material can further be reduced, adhesion of a raw material can be suppressed and prevented further than before.
When the heating means is provided in the hollow short tube group, for example, when the stirring device is cleaned, water heated by the heating means can flow into each hollow short tube, so that the sterilization processing of the device is possible. This makes it possible to produce hygienic and stable quality products. In addition, for example, since it is not necessary to carry hot water from another place and supply it into the stirring device, workability at the time of cleaning the stirring device is good.
Here, when a heating means has a container for hot water manufacture and the heater installed in the inside, water can be heated by simple structure.

Furthermore, when each hollow short tube has a structure that can be detached from the adjacent hollow short tube, for example, after using the stirrer, each hollow short tube is removed to leave the raw material inside the hollow short tube. Even if it adheres, the inside of the hollow short pipe can be easily and reliably cleaned, and maintenance is very easy.
When the raw material is a chlorophyll-containing material mainly composed of either or both of potato dung and crushed potato and an extraction solvent, chlorophyll in the chlorophyll-containing material can be extracted into the extraction solvent. Moreover, when the raw material is chlorophyll containing water and fat and water, chlorophyll and water can be mixed in an emulsified state.
Thereby, the chlorophyll drink which contains many effective ingredients can be manufactured.

Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.

A sectional view taken along the line aa, (C) is a sectional view taken along the line bb of FIG. 1, FIG. 3 is an explanatory view of the stirring device according to the second embodiment of the present invention, and FIG. Explanatory drawing of the ultrasonic vibrator used for a stirring apparatus, (B) is a front view of the attachment components of the ultrasonic vibrator.

As shown in FIGS. 1 and 2, the stirring device 10 according to the first embodiment of the present invention has a raw material inlets 11 to 14 at an upstream end (one end) and a downstream end (others). A hollow short tube group in which cylindrical hollow short pipes 19 to 22 each provided with raw material outlets 15 to 18 are connected in series in a plurality of stages (here, four stages) in series; The inflow ports 11 to 14 are devices that are directed substantially in the tangential direction with respect to the inner wall surfaces of the hollow short tubes 19 to 22, for example, devices that are suitable for use in extraction processing or emulsification processing. This will be described in detail below.

The hollow short tubes 19 to 22 are arranged in a zigzag shape in the vertical direction with the inflow ports 11 to 14 being high and the outflow ports 15 to 18 being inclined to be low, and the hollow short tubes 19 to 22 are hollow. Connecting pipes forming the inlet 12 of the short tube 20, the outlet 16 of the hollow short tube 20, the inlet 13 of the hollow short tube 21, and the outlet 17 of the hollow short tube 21 and the inlet 14 of the hollow short tube 22, respectively. 23 to 25 connect the adjacent hollow short tubes 19 and 20, the hollow short tubes 20 and 21, and the hollow short tubes 21 and 22. Each of the hollow short tubes 19 to 22 has an angle α, β, γ, and δ (for example, the upper limit is 20 degrees, preferably 10 degrees, more preferably 5 degrees, and the lower limit is 0.5) with respect to the ground surface. In a range of 1 degree, preferably within a range of 1 degree.

Each of the hollow short tubes 19 to 22 is made of corrosion-resistant stainless steel. For example, the inner diameter is 10 cm to 30 cm and the length is 1 m to 2 m (here, the inner diameter is 20 cm and the length is 1. 5 m and its internal volume is about 47 liters). The inner diameter of each hollow short tube is not limited to the above-described inner diameter as long as the raw material can be swirled therein, and can be dealt with by increasing the flow rate of the raw material when the inner diameter is increased. . Also, the length of each hollow short tube is not limited to the above-described length as long as the inside can be cleaned, but more than necessary when considering the attenuation of swirling flow There is no need to lengthen it.

As shown in FIG. 2 (A), the hollow short pipe 19 arranged at the uppermost stage is formed into a cylindrical shape with a pipe body 28 provided with flange portions 26 and 27 at both ends thereof, and the flange portions 26. , 27 and cover members 31 and 32 having flange portions 29 and 30 respectively abutting on the contact portions 27 and 27. In use, a sealing material (not shown) is disposed between the flange portions 26 and 27 of the pipe main body 28 and the flange portions 29 and 30 of the lid members 31 and 32, and the flange portions 26 and 29 are connected to each other. The hermetically sealed state is maintained by tightening the flange portions 27 and 30 with bolts (not shown). Here, each hollow short tube can also be configured by a tube body that does not include a flange portion, and a lid member that can be attached to and detached from the tube body by, for example, a screw.
The other hollow short tubes 20 to 22 have substantially the same configuration as the hollow short tube 19.

As shown in FIGS. 1, 2 (A), and 2 (B), the downstream end of the first connecting pipe 33 that forms the raw material inlet 11 is connected to the upstream end of the hollow short tube 19. The inflow port 11 is directed in a substantially tangential direction with respect to the inner wall surface 34 of the hollow short tube 19. Since the hollow short tube 19 is positioned on the most upstream side of the hollow short tube group, the inlet 11 for the raw material corresponds to the liquid inlet of the hollow short tube group.
As shown in FIG. 2A, the axial center of the downstream end portion of the first connection pipe 33 has an angle ε (for example, with respect to a direction perpendicular to the axial center m of the hollow short tube 19 in a plan view. For example, the upper limit is inclined by 20 degrees, preferably 10 degrees, more preferably 5 degrees, and the lower limit is 0.5 degrees, preferably within a range of 1 degree.

The downstream end of the hollow short tube 19 is connected to a connecting pipe 23 that forms the raw material outlet 15, and the outlet 15 coincides with the inner wall surface 34 of the hollow short tube 19 in a substantially tangential direction. It is supposed to be. As a result, as shown in FIG. 2 (B), the raw material flowing into the hollow short tube 19 from the first connecting pipe 33 and swirling clockwise in the hollow short tube 19 is changed in its swirling direction. It is possible to flow out from the connection pipe 23 without any trouble. Since the axis of the connecting pipe 23 is substantially perpendicular to the ground surface, the angle α is only perpendicular to the direction perpendicular to the axis of the hollow short tube 19 inclined by the angle α with respect to the ground surface. Inclined.

Here, the inner wall surface 34 of the hollow short tube 19, the outer inner wall surface (raw material contact surface) 35 at the downstream end of the first connecting pipe 33, and the outer inner wall surface (raw material contact) at the upstream end of the connection pipe 23. (Surface) 36 forms a continuous surface with no steps.
As a result, the raw material flowing in from the first connecting pipe 33 not only swirls in the vicinity of the inlet 11 of the hollow pipe 19 but also along the inner wall surface 34 from the upstream side to the downstream side of the hollow pipe 19. While swirling, a swirl flow is formed and flows out from the connection pipe 23 forming the outflow port 15 without staying.

As shown in FIGS. 1 and 2C, the connection pipe 23 connected to the hollow short tube 19 is connected to the upstream end of the second-stage hollow short tube 20. The connection pipe 23 forms the raw material inlet 12 of the second-stage hollow short tube 20, and the inlet 12 is substantially tangential to the inner wall surface 37 at the upstream end of the hollow short tube 20. Is connected to the hollow short tube 20. A connecting pipe 24 that forms the raw material outlet 16 is connected to the inner wall surface 37 at the downstream end of the hollow short tube 20.
Also in this hollow short tube 20, the axis of each connecting pipe 23, 24 is substantially perpendicular to the ground surface, so that it is perpendicular to the axis of the hollow short tube 20 inclined at an angle β with respect to the ground surface. It is inclined by an angle β with respect to the correct direction.

Thereby, the raw material flowing into the second-stage hollow short pipe 20 from the connection pipe 23 connected to the uppermost hollow short pipe 19 not only swirls in the vicinity of the inlet 12 of the hollow pipe 20, From the connecting pipe 24 connected to the third stage hollow short pipe 21 without staying while forming a swirling flow while swirling along the inner wall surface 37 from the upstream side to the downstream side of the hollow pipe 20. leak.
For the other short hollow tubes, that is, the third and fourth-stage hollow short tubes 21 and 22, the raw material outlet 18 is provided in the axial centers of the connecting pipes 24 and 25 and the lowermost hollow short tube 22. Is formed at an angle γ and a direction perpendicular to the axis of the hollow short tubes 21 and 22 inclined by the angles γ and δ with respect to the ground surface. Each is inclined by δ. Since the hollow short tube 22 is located on the most downstream side of the hollow short tube group, the outlet 18 of the raw material corresponds to the liquid outlet of the hollow short tube group.
Here, each of the hollow short tubes 19 to 22 has a structure that can be attached to and detached from the first connecting pipe 33, the connecting pipes 23 to 25, and the second connecting pipe 38, for example, by screws or one-touch type. It has become.

As shown in FIG. 1, the upstream end of the first connection pipe 33 of the hollow short pipe 19 arranged at the uppermost stage and the downstream of the second connection pipe 38 of the hollow short pipe 22 arranged at the lowermost stage. The side end portion is connected to a raw material transfer pump 39, and the raw material is supplied at a flow rate of, for example, 0.1 m ³ / min to 0.5 m ³ / min (here 0.3 m ³ / min). It is possible to send to the group. Thereby, the raw material can pass through the hollow short tubes 19 to 22 in, for example, 5 seconds to 30 seconds (here, about 10 seconds). The flow rate of the raw material is not limited to the numerical range described above, and can be further increased by adjusting the size of each hollow short tube and the operation output of the raw material transfer pump, for example.

The first connecting pipe 33 and the second connecting pipe 38 are connected via a raw material transfer pump 39 to form a connecting pipe, and the hollow short pipe group in which the hollow short pipes 19 to 22 are connected in series. The liquid outlet is connected to the inlet of the hollow short tube group via the raw material transport pump 39 and the connecting pipe, and the flow path 40 for circulating the raw material in the same system is formed. Thereby, since it can circulate and process a raw material, without using the stirring tank and the stirring blade installed in the inside like conventional, for example, an apparatus structure can be made compact.

Since the flow path 40 is a system closed to the outside, a pipe 42 provided with an air vent valve 41 is attached to the upper part of the uppermost hollow short pipe 19, and the stirring device 10. The internal pressure can be adjusted.
Further, a raw material extraction pipe 44 provided with a raw material extraction valve 43 is connected to the raw material transfer pump 39 side of the first connection pipe 33 of the hollow short pipe 19 arranged at the uppermost stage. The second connecting pipe 38 connected to the hollow short pipe 22 arranged at the lowermost stage is provided with a raw material supply pipe 47 connected to the raw material storage tank 45 and provided with a raw material supply valve 46. Yes.

Here, at the upstream end of the second-stage hollow short pipe 20, the hollow short pipe 20 and the first connecting pipe 33 are connected, and the inflow pipe provided with the raw material inflow reserve valves 48 and 49 is provided. 50 can also be provided. By configuring in this way, when the amount of the raw material is small, by closing the valve 59 that opens and closes the flow path on the downstream side of the first connection pipe 33 and opening the raw material inflow preliminary valves 48 and 49, The raw material (for example, liquid) flows into the second hollow short tube 20 via the inflow pipe 50 without flowing into the uppermost hollow short tube 19.
Such a configuration can be applied to the hollow short tubes 21 and 22 in the third and fourth stages.
Thereby, since the flow path of the raw material of a stirring apparatus can be changed according to the amount of raw materials, a small amount extraction or emulsification of a raw material can be implemented efficiently.

As shown in FIG. 1, a heating means 52 is connected to the hollow short tube 22 and the second connecting pipe 38 arranged at the lowermost stage.
The heating means 52 includes a heat-resistant hot water production container 54 in which a heater 53 is disposed, and an upstream end thereof is at the downstream lower portion of the hollow short tube 22 and a downstream end thereof is a second end. The connection pipe 38 is connected via connection pipes 57 and 58 provided via valves 55 and 56.
Thereby, the water that has flowed into the flow path 40 through the above-described raw material supply pipe 47 is stored in the hot water production container 54 and heated by the heater 53, for example, heat of 85 ° C. or more and 100 ° C. or less. After the water is produced, hot water can be flowed into the flow path 40 using the raw material transport pump 39 to perform high-temperature sterilization treatment.
In addition, the water introduced into all the hollow short tubes 19 to 22, the connecting pipes, and the hot water production vessel 54 is circulated by the raw material transport pump 39 to produce, for example, hot water of 85 ° C. or more and 100 ° C. or less. However, high-temperature sterilization treatment can also be performed.
Here, since the hot water producing container 54 is structured to be detachable with respect to the connection pipes 57 and 58 similarly to the hollow short pipes 19 to 22 described above, cleaning is easy.
Note that the used hot water can be discharged to the outside through the raw material extraction pipe 44.

The stirring device 10 is mainly composed of a straight pipe and a joint (union). For example, the stirring device 10 has a structure that can be attached to and detached from each other by screws or bolts. Each member can be cleaned, and maintenance is very easy.
Moreover, since the stirring apparatus 10 can be manufactured by combining each member of a commercial product (standard product) as described above, it is not necessary to manufacture each member specially and can be manufactured at low cost.
And, for example, by eliminating the conventionally used tank and configuring the stirring device 10 mainly using a straight pipe, all the raw materials can always circulate in the flow path 40 of the stirring device 10. There is no stagnation.

Then, the usage method of above-described stirring apparatus 10 is demonstrated.
First, for example, a slurry-like raw material is stored in the storage layer 45, and then the valve 59 of the first connection pipe 33 and the flow path of the second connection pipe 38 connected to the raw material transfer pump 39 are opened and closed. 60, the air vent valve 41 and the raw material supply valve 46 are opened, and the valves 55 and 56 of the connection pipes 57 and 58 connected to the hot water production vessel 54 and the raw material take-out valve 43 are closed. Then, the raw material transfer pump 39 is started. Thereby, the raw material flows into the stirring device 10. In addition, for example, the solid material which is a pulverized material can be introduced from the pipe 42 of the uppermost hollow short tube 19.
At this time, the amount of the raw material that flows into the stirring device 10 is, for example, about 50% by volume to 100% by volume of the volume of all the hollow short tubes 19-22. In addition, when the valve 59 of the first connection pipe 33 is closed, the raw material inflow preliminary valves 48 and 49 are opened, and the uppermost hollow short pipe 19 is not used, the amount of the raw material is set to each of the hollow short pipes 20 to 22. For example, the volume is about 50% by volume to 100% by volume.

After supplying a predetermined amount of raw material into the flow path 40 of the stirring device 10, the air vent valve 41 and the raw material supply valve 46, which have been opened, are closed, and the flow rate of the raw material satisfies the above-described conditions. The raw material transfer pump 39 is operated and controlled so as to be within the range to be used. Since the raw material flowing in the uppermost hollow short tube 19 swirls in the hollow short tube 19, even if the air vent valve 41 is kept open, the raw material is hardly blown out. At this time, the raw material can be supplied from the pipe 42, and in this case, the raw material is drawn into the hollow short tube 19 by the suction action in the hollow short tube 19.
Here, the flow rate of the raw material can be confirmed, for example, by providing a flow meter (not shown) in the first connection pipe 33 or the second connection pipe 38 connected to the raw material transfer pump 39.

Thereby, the raw material flowing in the first connecting pipe 33 by the raw material transport pump 39 flows into the hollow short pipe 19 along the inner wall surface 34 at the upstream end of the uppermost hollow short pipe 19, and the flow velocity thereof. Is discharged from the connection pipe 23 while turning along the inner wall surface 34 of the hollow short tube 19 by the centrifugal force obtained by the above.
When the valve 59 of the first connection pipe 33 is closed and the raw material inflow preparatory valves 48 and 49 are opened and the uppermost hollow short pipe 19 is not used, the first connection pipe 39 is used by the raw material transfer pump 39. The raw material flowing through the inside 33 flows into the hollow short tube 20 through the inflow pipe 50 along the inner wall surface 37 at the upstream end of the second-stage hollow short tube 20.

The raw material discharged to the connection pipe 23 is stirred while generating a swirling flow in each of the hollow short pipes 20 to 22 connected in series to the hollow short pipe 19 as described above. It is discharged from the hollow short tube 22 to the second connecting pipe 38. This operation is repeated a plurality of times for a preset predetermined time to stir the raw material.
After the raw material agitation processing is completed, the valve 59 of the first connecting pipe 33 connected to the raw material transfer pump 39 that has been opened is closed, and the air vent valve 41 and The raw material extraction valve 43 is opened. Then, the raw material transfer pump 39 is stopped after the processed raw material in the flow path 40 of the stirring device 10 is taken out from the raw material extraction pipe 44 by the operation of the raw material transfer pump 39.

In addition, as a raw material, for example, chlorophyll mainly composed of either one or both of feces and pulverized cocoons (for example, 80% by mass or more, preferably 90% by mass or more, more preferably 95% by mass or more). A mixture of the content and ethyl alcohol (an example of a solvent for extraction), or a mixture of chlorophyll containing oil and water and water can be used.
This chlorophyll contains oil and fat and is likely to stick to the inside of the flow path 40 of the stirring device 10, but the device configuration is simple (in each hollow short tube 19 to 22, there is a spiral as in the conventional case). Therefore, for example, it is difficult for the raw material to stay, adhere to, and remain within the flow path 40.
Therefore, the stirring device 10 conveys a mixture of the chlorophyll-containing material and ethyl alcohol while stirring, and extracts the chlorophyll from the chlorophyll-containing material into ethyl alcohol, or a mixture of chlorophyll and water containing fat and oil. It can convey while stirring and can perform the emulsification process which disperse-mixes chlorophyll and water in an emulsified state.

In addition, other raw materials can be used as raw materials, for example, animal raw materials (for example, deer horn powder) or vegetable raw materials (for example, carrots, wolfberry, or bitter gourd), and by performing extraction treatment or emulsification treatment, It is also possible to produce foods, cosmetics or fragrances.
Here, for example, with respect to deer horn powder, an extract (active ingredient) can be produced by applying a mixture of this powder and alcohol to the stirring device 10 and performing an extraction treatment. Moreover, about carrot and wolfberry, an extract can be manufactured by performing the extraction process with the stirring apparatus 10 with alcohol or water.
In particular, it was confirmed that the extract obtained by applying ginseng to the stirrer 10 and performing the extraction process is an extract that can produce ginseng liquor with the same quality as a conventional one drop. Thus, the stirring device 10 is a device that can extract an extract efficiently in a short time.

As described above, after the treated raw material is taken out from the flow path 40 of the stirring device 10, the stirring device 10 is continuously cleaned.
First, after washing water is stored in the storage tank 45, the valve 59 of the first connection pipe 33, the valve 60 of the second connection pipe 38, the air vent valve 41, and the material supply supply connected to the raw material transfer pump 39. The valve 46 and the valves 55 and 56 of the connection pipes 57 and 58 connected to the hot water production container 54 are opened, the material take-out valve 43 is closed, and the material transport pump 39 is started.
Thereby, the washing water is caused to flow through the flow path 40 of the stirring device 10. At this time, the amount of the washing water flowing through the flow path 40 includes the hollow short pipes 19 to 22, the connection pipes 23 to 25, the first connection pipe 33, the second connection pipe 38, the hot water production container 54, and For example, the inner volume of each of the connection pipes 57 and 58 is about 50% by volume to 100% by volume. It is also possible to supply cleaning water into the agitator 10 with a water faucet opened after a hose (not shown) connected to a water faucet is directly connected to the raw material supply pipe 47.

After supplying a predetermined amount of washing water to the flow path 40 of the agitator 10, the air vent valve 41 that is open is kept open, and the raw material supply valve 46 that is open is closed. Then, the raw material transport pump 39 is operated, the heater 53 is energized, and the (circulation) washing water flowing into the hot water production container 54 is heated to become hot water. Thereby, the inside of the stirring apparatus 10 can be high-temperature sterilized.
In addition, the temperature of the hot water flowing through the stirring device 10 is lowered by its use. For this reason, by opening the valves 55 and 56 of the connection pipes 57 and 58 connected to the hot water production vessel 54 and heating the hot water even during sterilization, the temperature drop of the hot water is suppressed as much as possible. can do.

After the sterilization process is completed, the valve 59 of the first connection pipe 33 connected to the raw material transporting pump 39 that is in the open state is closed, and the air vent valve 41 and the raw material take-out valve that are in the closed state are closed. The valve 43 is opened. Then, by operating the raw material transport pump 39, the processed hot water in the stirring device 10 is taken out from the raw material extraction pipe 44, and then the raw material transport pump 39 is stopped.
As described above, since the device configuration of the stirring device 10 is simple, sterilization treatment can be easily performed.
Thus, the sterilization process of the stirring apparatus 10 is performed. In addition, before flowing hot water in the stirring apparatus 10, it is also possible to remove the deposit | attachment in the stirring apparatus 10 previously using the washing water before a heating.

Next, a stirring device 70 according to a second embodiment of the present invention will be described. This stirring device 70 is a part of the hollow short tubes 19 to 22 of the stirring device 10 described above (here, the third stage). The hollow short tubes 21) are replaced with transport tubes 71 to 73 through which raw materials flow linearly. Accordingly, the same members as those used in the stirring device 10 are denoted by the same reference numerals.

Each of the transport pipes 71 to 73 is arranged in a zigzag manner (three in this case) in the height direction between the second-stage hollow short pipe 20 and the lowermost hollow short pipe 22. The downstream end of the transport pipe 71 located at the uppermost stage is connected to a connection pipe 74 connected to the upstream end of the transport pipe 72 located at the second stage, and the downstream end of the transport pipe 72 is The connection pipe 75 is connected to the upstream end of the transport pipe 73 located at the lowest stage.
The upstream end of the transport pipe 71 located at the uppermost stage is connected to a connection pipe 76 that forms the outlet 16 of the second-stage hollow short pipe 20, and is downstream of the transport pipe 73 located at the lowermost stage.
