Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extraction device for extracting a dashi component from dashi stock such as bonito flakes and kelp, and in particular, workability and extraction efficiency can be improved by performing the extraction and the solid-liquid separation in the same device. The present invention relates to an excellent extraction device and a method of selling the extraction device on the premise of this high efficiency.

2. Description of the Related Art Inosinic acid, glutamic acid and the like extracted from knotobushi, mackerel, murobushi and other soup stocks and kelp and soup stock are widely used as seasonings as broth ingredients with umami and unique flavors. There is. The soup stock used in the food processing industry, etc., is extracted by combining the above-mentioned soup stock materials with our own know-how, because the taste and flavor are important.

A conventional dashi extraction device will be described with reference to FIG. The conventional general dashi extraction uses the extraction device 11 and the solid-liquid separation device 12 together, and the extraction is performed by the extraction device 11.
The solid-liquid separation device 12 is used for the solid-liquid separation of the stock material and the extract. The extraction device 11 has a stirrer 13 for efficiently promoting the extraction and a heater (not shown) for heating the stock material liquid in the device. Further, the solid-liquid separation device 12 has a solid-liquid separation wire net 14. In the extraction device 11, after extracting the broth component from the broth raw material at a predetermined temperature for a predetermined time with stirring, the extraction liquid containing the broth raw material as a solid content is transferred to a solid-liquid separation device 12 to separate the broth raw material and the extraction liquid. To separate. Since the soup stock can be extracted several times, the solid-liquid separation device 1 is used as the residue after the soup stock extraction.
However, the raw material remains in the solid-liquid separation wire net 14 of No. 2 but is returned to the extraction device 11 again, and extraction is performed in the same manner as the previous time. Repeated extraction of soup stock can be performed as long as the concentration of soup stock in the extract is maintained at a predetermined value, and the general extraction limit is about 2 to 3 times although it varies slightly depending on the stock.

To improve the extraction efficiency of soup stock, (1)
Extraction stock is increased by increasing the extraction solvent to reduce the solid-liquid ratio. (2) As shown in Fig. 2, a stirrer is installed in the extraction container to stir the extraction stock and hot water and other extraction solvents. (3) The same raw material is repeatedly used as described above, and the extraction solvent is replaced with a new solution each time extraction is performed, and the extraction is repeated.

Further, in order to obtain a high-concentration stock extract, there is a circulation extraction method in which the stock material and the extract once extracted are returned to the extraction container and re-extracted using the extract.

[0006] The conventional selling method of the soup stock extraction device is similar to that of other mechanical devices, and the user generally pays all the device main cost and other various costs at the time of sale.

[0007]

However, in the extraction of soup stock, the amount of extraction solvent for the stock stock is often fixed. For this reason, there is a problem that a method of increasing the extraction efficiency by using a large amount of extraction solvent for the raw material cannot be used. Further, when the extraction liquid is circulated and the extraction is repeated, the concentration of the broth component in the extraction liquid increases, and the difference in concentration with the broth raw material becomes small, which makes it difficult to proceed with the extraction. Further, stirring cannot be performed unless there is a sufficient amount of liquid in the extraction container, so that there is a problem that the extraction efficiency is reduced in this case as well.

[0008] When the conventional extraction of the stock component and the solid-liquid separation of the stock material residue after extraction and the extraction liquid are carried out using separate devices, the steps such as the recycling of the stock material are complicated and complicated. There is also a problem that the cost is high because the number of required workers increases. In addition, if the process becomes complicated, the number of places such as the connecting portion between the extraction device and the solid-liquid separation device will inevitably increase, and the maintenance of the device will be complicated.

The soup stock extractor and the like are expensive to purchase, and a careful investigation is required at the time of purchase. With conventional sales methods, users are not sure whether they will get the desired effect after purchase. In addition, after purchase, there are cases in which sufficient effects may not be obtained, and there is a problem that it is not easy to adopt new equipment.

The present invention has been made to cope with such a problem, and in an extraction device for extracting a dashi component from a dashi material such as dried bonito and kelp, the extraction of the dashi component and the dashi material and the extraction liquid are performed. It is possible to perform solid-liquid separation with and using the same device, which is excellent in workability and has an excellent extraction rate, but an extraction device, and a method of selling the extraction device that allows users to purchase with confidence on the premise of this high efficiency. With the goal.

In addition, as the elution of the broth component from the broth raw material into the extraction solvent proceeds in the broth extraction container, the concentration of the broth component in the extraction solvent increases, so the concentration gradient between the broth raw material and the extraction solvent decreases. However, according to the present invention, the concentration gradient is kept constant and the extraction can be stably performed, and the extraction efficiency is excellent in the present invention.

By installing a pump in the path of the liquid discharge pipe, the filtration in the filtration wire mesh portion is performed while sucking with the pump, so that the filtration time can be shortened.

By connecting the liquid injection pipe and the liquid discharge pipe, it is possible to easily inject again the extracted liquid discharged using the pump installed in the pipe path into the extraction container. As described above, a high-concentration extract can be obtained by circulating the extract obtained by extracting the soup component from the once-stocked raw material and performing the extraction again using this extract.

BEST MODE FOR CARRYING OUT THE INVENTION A soup stock extraction device of the present invention will be described with reference to FIG. FIG. 1 is a schematic sectional view of a dashi extractor according to an embodiment of the present invention. In the extraction container 1, a stirrer 3 having a stirring blade 3a for stirring the stock material liquid consisting of stock material and an extraction solvent inside the container is provided for adjusting the temperature of the stock material solution in the container in the side wall surface of the container. To heater 4
However, at the bottom of the container, a lid 5 having a wire mesh 5a for filtration for solid-liquid separation of the stock material and the extract is installed, respectively. The lid 5 is openably and closably attached to the bottom surface of the extraction container 1 by a clamp or the like so that the lid 5 can be easily opened and closed at the time of cleaning or the like. The lid 5 is provided with a liquid discharge pipe 8 and a drain drain (not shown).

The liquid circulation device 2 is for injecting the extraction liquid into the extraction container 1 during circulation, and a liquid injection pipe 7 for discharging the extraction liquid after solid-liquid separation which is connected to the lid portion. Liquid discharge pipe 8, pump 10 installed in the pipe path as power for injection or discharge, liquid level detection sensor 6 for detecting the liquid height inside extraction container 1, and liquid from this sensor And a controller (not shown) that controls the pump so as to circulate a predetermined amount of liquid based on the height information. In the soup stock extractor of the present invention, the liquid injection pipe 7 and the liquid discharge pipe 8 are connected so that the extraction liquid can be returned to the extraction container and the circulation extraction can be performed again with this extraction liquid. ing.

The procedure for extracting the stock component from the stock material by the stock extraction device of the present invention will be described in accordance with the following (1) to (5). (1) After putting the stock material such as bonito flakes and kelp into the extraction container 1, close the air valves 9a, 9b, 9e, and
After opening c and 9d, water, hot water, or those obtained by adding a seasoning or the like is injected as an extraction solvent from the liquid discharge pipe 8. (2) After the extraction, extraction is performed while stirring the stock solution containing the stock material and the extraction solvent with the stirrer 3. Further, during extraction, the soup stock solution in the container is heated by the heater 4 so as to maintain a constant temperature so that the soup stock is easily melted. (3) After the extraction by stirring is completed, the raw material liquid is filtered by the wire mesh 5a of the lid 5 while sucking with the pump 10 to obtain the extract liquid. When the extraction liquid is circulated here, the air valves 9b and 9c are closed and 9a, 9d and 9e are closed.
Open to connect the liquid injection pipe 7 and the liquid discharge pipe 8,
The extraction liquid obtained by the pump 10 is again used for liquid injection piping 7
To the inside of the extraction container 1. The circulation is repeated for a predetermined time while the pump 10 sucks at a pressure specified for each raw material. (4) After the circulation operation is completed, the air valves 9a, 9c, 9
e is closed, 9b and 9d are opened, and suction is performed by the pump 10 to obtain the extraction liquid from the liquid discharge pipe 8. A control device (not shown) controls so that the amount of liquid in the extraction container 1 is maintained at a predetermined amount during liquid collection. Specifically, the air valve 9a,
Since the liquid injection pipe 7 and the liquid discharge pipe 8 can be used independently by closing 9c, the liquid height detection sensor 6 is used during the liquid collection from the liquid discharge pipe 8 using the pump 10. The liquid height in the extraction container 1 is detected, and when the liquid height falls below the sensor 6, the air valve 9e is opened to inject a new amount of the extraction solvent from the liquid injection pipe 7. (5) After the addition of a predetermined amount of new liquid is completed, the heating by the heater 4 is stopped and the liquid is drained from the liquid discharge pipe 8.

The soup stock extraction device of the present invention performs the stirring extraction in the extraction container 1 and the wire mesh 5a for filtration provided on the lid.
Since it is possible to perform solid-liquid separation of the soup stock and the extract,
Compared to the conventional case where the extraction and the solid-liquid separation are performed by separate devices, the work steps such as moving the stock material and the stock extract liquid between the devices are reduced. As a result, it is possible to reduce labor costs and other costs associated with the reduced work process, and because the number of processes is reduced, the number of equipment failure points is also reduced.
Maintenance of the device becomes easy.

Since the lid portion 5 is hinged to the bottom portion of the extraction container 1 as a lower lid so that it can be opened and closed, the post-treatment after the completion of the extraction operation is performed by opening the lid portion 5 with a clamp or the like as a fulcrum. However, it can be easily carried out by scraping off the raw material residue left on 5a into a residue container (not shown) arranged below the extraction container 1.

The stirring blades 3a of the stirrer 3 can be changed in the number to be installed and the blade shape depending on the extraction conditions such as the stock material used and the extraction solvent. Further, a baffle may be provided on the inner wall of the extraction container 1 to promote stirring.

As the heater 4 installed on the wall surface of the extraction container, one using electromagnetic induction or steam can be used.
The extraction temperature differs depending on the stock material, and the temperature during stock extraction easily affects the flavor and so on.Therefore, a heater that uses steam is used because it is less likely to cause uneven heating and is easy to reuse in the factory. It is suitable for the present invention. Further, in the soup extraction device of the present invention, since the lid portion at the bottom of the extraction container is filtered at the same time as the extraction, the stock material for the soup is easily deposited on the bottom of the extraction container 1. For this reason, the elution of the dashi component mainly occurs around the bottom portion, so that it is efficient and preferable to install the heater 4 around the bottom portion of the extraction container 1.

The liquid level detecting sensor 6 can be arranged at an arbitrary position of the extraction container 1. Further, since the liquid height in the extraction container 1 also changes depending on the extent of extraction, it is preferable to install the liquid height detection sensor 6 in the extraction container 1 at a plurality of different heights.

Liquid level detection sensor 6, air valve 9
The liquid height of the extraction container 1 can be maintained at the designated height by controlling e by a control device (not shown) and injecting a new extraction solvent corresponding to the liquid decrease amount through the liquid injection pipe. As a result, since a new extraction solvent (new solution) is sequentially supplied, a decrease in the concentration gradient between the stock material and the extraction solvent due to the progress of extraction, which causes a decrease in extraction efficiency, is suppressed,
Excellent extraction efficiency because a large concentration difference can be maintained at all times.

In the broth extraction apparatus of the present invention, the injection amount of the new liquid serving as the extraction solvent may be the same as the discharge amount of the extraction liquid, and the amount of extraction solvent required until the extraction is completed may be small. This required amount of solvent is much smaller than the case where all extraction solvents are replaced and extraction is repeated, and it is suitable for extraction when the amount of extraction solvent cannot be secured sufficiently. The obtained extract has a predetermined concentration range and has a sufficient umami and flavor.

Since a small amount of liquid is required at the time of extraction, the size of the extraction device can be greatly reduced as compared with the conventional one.

The solid-liquid separation by filtration in the present invention is performed while sucking with a pump, so that the filtration time can be shortened. In addition, the suction raw material is pressed onto the wire mesh 5a for filtration to be in a state of being pressed, which delays the progress of the filtration. Further, although the agitator 3 is provided in the extraction container 1, the agitator 3 is pressed at the bottom, but the raw material cannot be agitated. Therefore, in the present invention, the suction of the pump 10 is temporarily stopped so that pressure is accumulated but the raw material is released from the suction pressure of the pump and diffused in the extraction container 1. Also,
This operation can be automatically performed on a regular basis by monitoring the change in suction pressure of the pump 10 due to the pressure buildup of the stock material on the filter wire mesh 5a.

The air valves 9b and 9c are closed, and 9a and 9c
By opening d and 9e and connecting the liquid injection pipe 7 and the liquid discharge pipe 8, the extraction liquid can be returned into the extraction container, and the circulation extraction can be performed by performing extraction again with this extraction liquid. Circulation extraction is used to obtain a high-concentration extract liquid, and after repeating circulation at a predetermined pressure for a predetermined time, valves 9a, 9c,
9e is closed and 9b and 9d are opened to obtain a highly concentrated extract liquid from the liquid discharge pipe 8.

In the extraction apparatus of the present invention, the continuous injection of the above-mentioned new liquid and the control of the circulation extraction can be automated by the control apparatus, so that the number of workers can be reduced.

Can be reduced. This sales method is premised on this high extraction efficiency and the accompanying reduction in raw material costs. The seller usually performs comparative measurement of the extraction rate between the stock extraction device of the present invention and the existing stock extraction device in the presence of the user. The measurement is performed using an actual machine or a reduced-scale demo machine under the same temperature conditions as in Table 1 above. Note that the calculation of the extraction rate follows Formula 1. Only when the user is satisfied with the measurement result, the user enters into a sales contract including terms such as payment of the usage fee after purchase, and pays the cost of the soup stock extraction device body. Either the user or the seller may pay for the installation cost of the device, and if the seller pays, the user should pay for it at the time of installation or add it to the usage fee for each period. You can also

By conducting an extraction rate measurement experiment using an actual machine or a demonstration machine, it is easy to accurately predict the raw material reduction amount calculated from the extraction rate and the like. In particular, in a measurement experiment using a demonstration machine, since a smaller one than the actual machine is used, the resistance of the raw material on the side of the extraction container during extraction is large.
Therefore, it can be expected that the actual machine has a higher extraction rate than the demo machine. As a result, users can purchase and use the device with confidence.

Since the usage fee to be paid after purchase is determined in advance, the user can easily make a budget plan thereafter. Also, since the raw material cost reduction amount is calculated based on the comparison measurement result,
Users can easily make accurate forecasts of cost recovery.

The payment of the usage fee can be freely negotiated between the user and the seller at any predetermined period or in a lump sum.

The usage fee may be a predetermined ratio of the difference between the conventional raw material cost required for a predetermined period and the actual raw material cost during the predetermined period and the same period.
As a result, the usage fee is calculated based on the cost that was actually reduced, so there is no deficit due to payment of the usage fee.

The soup stock extractor of the present invention has many advantages such as simple and stable work and small size in addition to the excellent extraction rate. All of the effects obtained by the stock extraction device of the invention can be obtained only at the cost of the device at the time of purchase. One feature of the method of selling the soup stock extraction device of the present invention is that the user returns a predetermined percentage of the stock material cost to the seller in exchange for the great effect and profit obtained by the device.
