2. Description of the Related Art The invention of Japanese Patent Laid-Open No. 4-252153 has been proposed as a means for collecting aroma by heating. This invention heats a food material to generate an aroma component, and then conveys the aroma component by a carrier gas, and then the aroma conveyed together with the carrier gas is passed through the aroma dissolving and collecting liquid to generate the aroma. A method of dissolving and collecting, and a heating unit that heats a raw material to generate an aroma component, a gas supply unit that conveys the aroma component together with a carrier gas, and an aroma that dissolves and collects the aroma conveyed by the gas supply unit. It is a device for collecting aroma composed of a collecting unit.

[0003] This aroma collection method and device collect food ingredients in the tank and generate aroma components by heating the tank, so that the food ingredients located far from the heat source are It is difficult to generate aroma components, and moreover, heating is concentrated in one part, so it is easy to raise the temperature partly, so that the generation of caramel odor and unnecessary components generated from accumulated carbides are also collected. There is a point.

The invention of JP-A-8-291298 is a method of heating a raw material to be heated such as meat and fish to generate an aroma component, and collecting the aroma component in a collecting liquid.

In this case, the problem of caramel odor is solved, but since the heating means is a gas stove, an electric stove, charcoal, etc., the temperature control cannot be controlled arbitrarily, and all the components of the raw material to be heated are collected. There is a problem that it does.

[0006]

Each of the conventional techniques has its own characteristics, but since it is a method of collecting all components and cannot control the temperature, it is not possible to collect a desired component with high accuracy. In addition, since the coefficient between the concentration of the collected liquid and the time cannot be grasped, it was necessary to control the concentration by another method such as a concentration sensor. The present invention obtains necessary components at a low cost by using a simple device, and thus, a novel method for collecting aroma components and charred components, which solves the conventional problems, and a device and a device for collecting the above components. The purpose is to provide.

[0007]

In order to achieve the above object, the invention according to claim 1 is such that a heater whose temperature can be adjusted is immersed in a liquid raw material at a low temperature and then the heater is pulled up from the liquid raw material. To raise the temperature and heat the liquid raw material attached to the heater to volatilize the aroma and charred components,
This is a method for collecting aroma components and charred components, which is characterized by dissolving this in a collection liquid.

As the liquid raw material, liquefied solid food or liquid such as lard is used.
Since the heater immersed in the liquid raw material has a low temperature, the liquid raw material does not burn directly. When the heater is pulled up from the liquid raw material, the liquid raw material attached to the surface
It vaporizes due to the rise in the temperature of the heater and produces aroma and charred components. Therefore, by controlling the temperature of the heater and setting the time, desired components ranging from an aroma component having a low specific gravity to a burning component having a high specific gravity can be obtained.

Further, by absorbing the aroma component and the charred component into the collecting liquid such as water and seasoning liquid, a collecting liquid having a good flavor containing the above components can be obtained.

There is also a method of impregnating the collected liquid by blowing the components generated from the liquid raw material into the collected liquid as in the case of the above-mentioned conventional collecting means. It is preferable that the collected liquid is jetted in the form of fine water droplets and is adsorbed and impregnated into the water droplets. By circulating this trapping liquid and continuously jetting it, it is possible to increase the concentration of the components in the trapping liquid, and in combination with the temperature adjustment of the heater and the setting of the time, the trapping liquid of the desired component concentration can be obtained. can get.

According to a third aspect of the present invention, in the above first aspect of the invention, the heater in a pulled-up state is heated to a high temperature, and the carbonized solid matter adhered to the heater is burned and cleaned. It is a method of collecting ingredients and charred ingredients.

According to the present invention, after the step of heating the heater to which the liquid raw material is adhered to volatilize the active ingredient, the heater is heated to a temperature of, for example, 1000 ° C. in order to prevent carbonized solids from being accumulated in the heater. It is intended to clean the heater by raising and burning the carbonized solids. By this self-cleaning of the heater, the generation efficiency of aroma components and burnt components and the generation of unnecessary components are prevented.

Further, in the above-mentioned inventions of claims 1 and 2, if the temperature zone depending on the liquid raw material is electronically controlled from a low temperature region to a medium temperature region with time, the components that can be collected have a wide range. Is possible. On the contrary, if the control temperature is fixed, a specific component can be collected. In addition, all components can be collected by sequentially controlling from the low temperature region to the high temperature region.

According to a fourth aspect of the present invention, a heater that can adjust the temperature from a low temperature region to a high temperature region is attached to one side of the transmission shaft that reciprocally rotates at a predetermined angle, and the heater is moved up and down by the rotation of the transmission shaft. Below the operating heater, a container for the liquid raw material that receives the heater when the heater descends is provided as a pair, and is a device for generating aroma components and burning components.

According to the present invention, a heater which can be moved up and down and whose temperature can be adjusted from a low temperature region to a high temperature region is immersed in a liquid raw material in a container arranged below the heater at a low temperature, and the heater is pulled up. After that, the temperature is raised and the liquid raw material adhering to the surface is heated to volatilize the aroma component and the burnt component.

Therefore, the aroma component and the burnt component can be quickly and efficiently vaporized from the liquid raw material by the raising and lowering operation of the heater and the temperature control. Further, by raising the temperature of the heater to a high temperature, the carbonized solid matter remaining on the surface of the heater can be burned, and the active ingredient can always be efficiently vaporized.

According to a fifth aspect of the present invention, the inside of the closed box is partitioned by partition walls having upper and lower vents to form a heating chamber and a collection chamber, and the heating chamber contains a liquid raw material. A container and a generator having a heater that dips the scent component and the charred component from the liquid raw material that adheres when rising to the heating chamber are installed, and a lower part of the heating chamber is equipped with an air filter. An intake port, an exhaust port equipped with a valve are provided at the top, a collection liquid jet nozzle is provided at the top of the collection chamber, and a collection liquid outlet is provided at the bottom of the collection chamber. It is a device for collecting aroma components and charred components, which is characterized in that the components are connected by a circulation pipe equipped with a pump.

The present invention is an apparatus used in the inventions of claims 1 to 3, and is an apparatus for collecting aroma components and charred components utilizing the invention of claim 4. Therefore, although the same action and effect as the invention of each claim are exhibited, since the intake port is provided in the lower part of the heating chamber, when the air in the box becomes lean, the outside air is automatically discharged from this intake port. Since it infiltrates, a decrease in the generation efficiency of the active ingredient is prevented. Further, since an exhaust port with a valve is provided in the upper part of the heating chamber, the opening of this valve allows unnecessary components to be promptly released to the outside of the box.

Due to the temperature change between the heating chamber and the collection chamber partitioned by the partition wall, and the water pressure of the collected liquid sprayed from the injection nozzle, the air containing the aroma component and the burnt component causes convection, and the upper and lower walls of the partition wall. It smoothly circulates in the box after passing through the ventilation hole provided in the, and the aroma component and the charred component are efficiently adsorbed and dissolved in the collection liquid.

An injection nozzle provided in the upper part of the collection chamber,
Since the outlet provided in the lower part of the collection chamber was connected by a circulation pipe equipped with a pump, the collected liquid retained in the lower part of the collection chamber was sucked up by the pump and circulated, whereby Collection efficiency is further improved.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a cross-sectional view showing an embodiment of an apparatus used in the method for collecting aroma components and charred components of the present invention. FIG. 2 is a perspective view of a device for generating an aroma component and a burnt component.

The box 1 shown in FIG. 1 is partitioned by a partition wall 4 provided with upper and lower vents 2 and 3, and a heating chamber 5 for generating an aroma component and a charring component, and the generated component dissolved in a collecting liquid 6. The collection chamber 7 is formed.

The heating chamber 5 is equipped with a device 8 for generating aroma and burnt components. As shown in FIG. 2, the generator 8 includes a container 10 for containing a liquid raw material 9 and an operating angle 2
Motor 11 and motor 1 that rotate left and right in the range of 5 degrees
1, a transmission shaft 12 that transmits the rotation of 1, a support 13 that supports the transmission shaft 12, a heat dissipation plate 14 that is fixed to the transmission shaft 12 in a horizontal state,
The heat radiating plate 14 includes a heater 15 attached to the tip of the radiating plate 14 and a base 16 to which the respective components are assembled. The base 16 is attached to an intermediate portion of the heating chamber 5. An intake port 18 with an air filter 17 is provided in the lower part of the heating chamber 5, and an exhaust port 20 provided with an exhaust valve 19 is provided in the upper part.

An injection nozzle 21 for the collected liquid 6 is provided in the upper part of the collection chamber 7, and an outlet 22 for the collected liquid 6 is provided in the lower part. The outer end of the injection nozzle 21 and the outer end of the outlet 22 are provided. And pump 2
They are connected by a circulation pipe 24 provided with 3. A series of operations of the above device is performed by a command from the control circuit 25 shown in FIG.

When the aroma component such as lard and the burnt component are collected by the above device, the liquid raw material 9 such as lard is put in the container 10 of the generator 8 installed in the heating chamber 5. Further, a predetermined amount of the collecting liquid 6 is put in the lower part of the collecting chamber 7 in which the generated components are dissolved. Although water is used as the collecting liquid 6, a commercially available seasoning liquid may be used as described later.

When the control circuit 25 is operated, the generator 8 and the pump 23 are operated by the command of the control circuit 25. A slight electric current flows through the heater 15 in the generator 8 to heat the heater 15 to a low temperature range of about 50 to 200 ° C., and when the motor 4 rotates in an angle range of 25 degrees, the transmission shaft 12 rotates and the heat dissipation plate 14 moves. The heater 15 that rotates and is attached to the tip of the heat dissipation plate 14 descends. When the heater 15 descends to the lowermost end, the liquid raw material 9 in the container 10 adheres to the surface of the heater 15. When the motor 4 starts reversing operation,
The heat dissipation plate 14 is inverted to the horizontal position, and the heater 15 rises.

At the same time as the heater 15 stops at the horizontal position, the current increases at an accelerating rate, and the medium temperature range is about 200 to 8
When the temperature is raised to 00 ° C, smoke having different components is generated depending on the specified temperature. As above, heater 15
By repeating the descending and ascending operations, the aroma component and the burnt component are continuously vaporized in the heating chamber 5. Heater 1
Although the immersion time of 5 in the liquid raw material 9 is instantaneous, it is 2 in the case of a liquid raw material obtained by liquefying a solid food, for example, a liquid raw material containing powdered or granular material obtained by crushing tea leaves or coffee beans and liquefying. The heating time in the middle temperature range of the heater 15 that has moved up is about 10 to 15 seconds when the liquid raw material is soy sauce, and about 5 seconds when it is oil.

On the other hand, when the pump 23 operates, the collected liquid 6 is sucked, and the collected liquid 6 is vigorously ejected from the injection nozzle 21 via the circulation pipe 24. An air flow 26 is generated by this injection energy. Air flow 2 on the partition 4 side
6 flows into the heating chamber 5 through the ventilation port 3, flows into the collection chamber 7 through the ventilation port 2 together with the target component in the heating chamber 5, and is ejected from the ejection nozzle 21 in the form of fine water droplets. It is dissolved and absorbed in the collected liquid 6.

After repeating the descending and ascending operations of the heater 15, the current value is raised to the maximum value and the temperature of the heater 15 is increased to about 1000 ° C. to burn the solid carbonized material adhering to the heater 15, to clean. Simultaneously with the increase of the current value, the valve 19 of the exhaust port 20 opens.

The unnecessary components generated by the self-cleaning of the heater 15 are discharged from the exhaust port 20 to the outside of the box 1 together with the rising airflow 27 generated by the heat of the heater 15. With this exhaust action, the outside air 28 enters the heating chamber 5 through the air inlet 17 through the air inlet 17.
Even when the air in the box 1 becomes lean due to the action of the heating device 8, the outside air 28 flows from the intake port 18 into the box 1
Naturally supplied within.

When an aroma component having a low specific gravity is to be collected, it can be collected by repeating the generation of the component in the low temperature region and the self-cleaning operation in the high temperature region. Moreover, when trying to collect a burnt component having a large specific gravity, the component generated in the low temperature region is discharged from the exhaust port 20, and the generation of the component in the medium temperature region or the high temperature region and the self-cleaning operation in the high temperature region are repeated. Can be collected by.

In the component generating operation according to the present invention, if the temperature setting and time distribution according to the collection purpose are determined,
Can be easily collected at the desired concentration. Therefore, it is not necessary to control the concentration of the collected liquid with a concentration sensor or the like, the mechanism of the device can be simplified, and the manufacturing cost of the device can be reduced.

An example of collecting aroma components of tea leaves using the above-mentioned collecting device is as follows. Mix the same weight of water with the raw material of raw tea leaves, put this in the container 10,
After controlling the low temperature range and raising the water temperature to 80 ° C, the equipment was operated and the aroma components generated in the low temperature range were extracted. , It was possible to collect the tea-specific components that can be perceived by the sense of smell when drinking special Sencha. The extraction of the aroma component is a result of the temperature control of the heater 15 and the opening / closing operation of the valve 19. If this collected liquid is added to, for example, a green tea beverage enclosed in a plastic bottle or the like, it can be transformed into a beverage having a special flavor of sencha with a unique tea flavor.

Next, an example of the case where the aroma component and the burnt component of soy sauce are collected using the above-mentioned collection device is as follows. The soy sauce stock solution was placed in the container 10 and electronically controlled from the middle temperature range to the high temperature range, and the charred component of soy sauce was adsorbed in the soy sauce stock solution used as the collecting solution 6, resulting in a fragrant grilled rice ball without bitterness. It was possible to obtain the seasoning liquid for fried rice crackers. The bitterness is not included in this seasoning liquid,
The bitterness component generated just before the carbonized solid matter burns out,
This is because the gas is discharged from the exhaust port 20.

In the above collecting device, the difference in scent in the temperature range of the heater was tested. Commercially available pure lard is used as the liquid raw material, water is used as the collection liquid, and each of the components in the middle temperature range and the high temperature range is circulated for 2 hours by the collection device to increase the concentration. The collected liquid was blended according to the composition shown in Table 1 to prepare a sausage of roast meat. When this was subjected to a sensory test by 10 panelists, the results shown in Table 2 were obtained.

[0036]

[Table 1]

[0037]

[Table 2]

A test was conducted in which lard was used as a liquid raw material, aroma components were generated in a medium temperature range (about 200 ° C. to 800 ° C.) and a high temperature range (about 1000 ° C.), and water was used as a collecting liquid to absorb the aroma components. It was At that time, the amount of water as the collection liquid and the time were changed, and the relation between the time and the concentration and the relation between the amount of the collection liquid and the agricultural degree were investigated. In addition, the concentration was measured because the aroma component became cloudy when dissolved in water as a collection liquid, and thus the cloudiness was measured. A turbidimeter was used as the measuring instrument, and the concentration was expressed by the number of the turbidimeter.

Further, as shown in FIG. 3, it has been found that the concentration of the aroma component in the collected liquid is approximately proportional to the time for which the collected liquid is brought into contact with the aroma component. It was also clarified that time can be controlled if the heater temperature and the amount of the collected liquid are constant.

Although the above-described embodiments of the present invention are intended for food as a liquid raw material, they can be carried out when a scent component is extracted and collected from a plant such as an herb, and similar effects can be obtained. Be done.

As described above, according to the present invention, a heater is directly immersed in a liquid raw material to deposit an appropriate amount of the liquid raw material on the surface, and the liquid raw material is heated at an appropriate temperature from a low temperature region to a high temperature region. However, since it is a method and apparatus for volatilizing and collecting desired aroma components and charred components in the liquid raw material, it is possible to easily generate and collect desired components by selecting heating temperature and heating time. You can

According to a second aspect of the present invention, the water pressure of the jet nozzle is used to generate fine water droplets of the air flow and the collected liquid,
When the aroma component and the burnt component are adsorbed and dissolved in the water droplets, the effective component can be easily and efficiently collected.

As in the third aspect of the present invention, by heating the heater at a high temperature and burning and removing the carbonized solid matter adhering to the heater, the generation efficiency of the active ingredient is reduced and the unnecessary ingredient is prevented from being mixed. be able to.

According to the fourth aspect of the invention, the aroma component and the burnt component can be quickly and efficiently volatilized from the liquid raw material by the raising and lowering operation of the heater and the temperature control.

According to the fifth aspect of the present invention, the aroma component and the charred component generated in the heating chamber are collected by the temperature difference between the high temperature heating chamber and the low temperature collecting chamber, and by the spray nozzle. Since the water pressure of the liquid smoothly circulates in the box, the collected liquid can be efficiently and promptly adsorbed and dissolved.

Further, since the collection liquid accumulated in the lower part of the collection chamber is sucked up by the pump and jetted from the jet nozzle, it is possible to further improve the collection efficiency of the aroma component and the charred component. The concentration can be adjusted by time control.

Furthermore, since it is a device that circulates the scent component and the charred component by utilizing the flow of air generated in the closed box and dissolves it in the collection liquid, it does not require a carrier gas as in the conventional case, Therefore, the mechanism of the device is simplified,
The manufacturing cost of the device can be significantly reduced.
