Description

Method and apparatus for production of raw oil {APPARATUS AND METHOD FOR MANUFACTURING PERILLA SEED OIL}

The present invention relates to a method and apparatus for producing raw oil, and more particularly, to a method and apparatus for producing raw oil that does not contain harmful substances such as benzopyrene.

Perilla (Scientific name: Perilla frutescens) refers to a perennial plant or its seed with the family Lamiaceae, which is native to Southeast Asia and India. It is presumed to have been planted since then.

Currently, the main types of perilla grown in Korea include Dongle No. 2, Namcheon Perilla, Perilla Perilla, Perilla Perilla, and Perilla Perilla, and perilla and sesame are distinctly different species.

Since these perilla seeds contain various useful ingredients, they are used as medicinal crops, oilseed crops, and leafy vegetables. In other words, perilla seeds contain a large amount of omega-3 fatty acid linolenic acid, which suppresses the synthesis of eicosanoids that cause adult diseases such as hypertension and allergic diseases, and improves learning ability and bioregulation functions such as lifespan effect. It is known that the seed fruit itself is used for sesame tea and confectionery as sesame seeds, and the oil extracted from the seed fruit is used for edible, pharmaceutical, and industrial purposes.

Perilla leaves contain perilla aldehyde, limonene, and perilla ketone, which have unique scents as vegetable essential oils, so they can remove the taste or fishy smell when eating pork or sashimi, and the unique aroma can enhance the taste and fresh leaves. It is used as a vegetable, and the extract of perilla leaves is used as a cosmetic pigment or fragrance.

Moreover, recently it is known that tocopherol can prevent cardiovascular disease and cancer, support immune function, and prevent and mitigate aging-related degenerative diseases, and the demand for perilla, one of the largest natural sources of tocopherol, is increasing. Is increasing.

In addition, according to'Donguibogam', perilla is described as having a warm, non-toxic nature, and taste is reduced. In addition, perilla moisturizes the liver, and when the seeds are boiled, the seeds make the body smooth and beautiful, and have the effect of encouraging energy. It has been described as'medicinal medicine fragment' in that it provides essence (bone marrow in the ear and bones), removes thirst and seawater, removes toxins from the body, and cleans the blood.

Perilla oil, a vegetable oil, is manufactured from these perilla seeds as a raw material and is one of the traditional cooking oils in Korea along with sesame oil. The characteristic is that in the fatty acid composition, saturated fatty acids are about 10% and the remaining 90% are unsaturated fatty acids. That is, α-linolenic acid (C18:3), which belongs to the three-dimensional polyunsaturated fatty acid, accounts for around 60%.

Many studies have been published on the physiological function of perilla oil with a high content of α-linolenic acid. Artificially induced colorectal and breast cancer proliferation suppression, improvement of learning ability, prevention of heart disease and thrombus caused by lowering platelet aggregation ability, and improvement of allergic constitution are attracting attention. It is an oil that plays an important role in maintaining the fatty acid balance. In addition, the perilla oil obtained by roasting and pressing the perilla seeds at 190~210℃ has a unique scent, but the content and pattern of the scent components vary depending on the roasting temperature.

On the other hand, there are various methods for preparing the perilla oil, which are prepared by roasting and pressing the perilla at a constant temperature and time. Among them, a method of roasting perilla using a roaster at a high temperature and then squeezing and extracting milk is extracted.

However, perilla oil produced by this general manufacturing method has a problem in that benzopyrene, which is a kind of polycyclic aromatic hydrocarbon compound, is generated when the perilla is roasted in the roasting step.

Polycyclic aromatic hydrocarbons (PAHs) are known to have over 200 derivatives, and their carcinogenicity has been found. Among them, benzopyrene (benzopyrene, 3,4-benzopyrene) has been found to be particularly strong carcinogenic. Benzopyrene, a carcinogen, contains not only carbon and hydrogen, but also other elements such as nitrogen, sulfur, and oxygen. It has a low solubility in water and has a property of soluble in oil, and is also produced by thermal decomposition by burning or high temperature. It is a substance that can be produced in the process of heating food in food, and is produced by incomplete combustion of carbohydrates, proteins, fats, etc., which are the main components of food during high-temperature cooking and processed cooking, especially char-grilled meat. , Benzopyrene was generated and detected in smoked products, and it is known to contain a lot of benzopyrene in processed foods and high-temperature cooked foods such as compressed oil and coffee.

The main cause of benzopyrene generation in the manufacture of perilla oil is in the roasting process.

The first is to use a stirrer to stir the sesame during the roasting process. At this time, as the stirrer rotates, a physical collision is applied to the sesame and the sesame is broken and many pieces are formed. These pieces burn easily, resulting in benzopyrene.

The second is that the roasting process takes place at high temperatures. Normally, the temperature for roasting sesame is made at a high temperature of 150 to 200°C, but roasting at a high temperature of 120°C or higher inevitably generates benzopyrene.

In this way, when the perilla oil is produced by roasting the perilla seeds, harmful components such as benzopyrene may occur above a standard value, resulting in a problem of deterioration in quality.

In order to solve this problem, there have been proposed methods for producing raw oil without going through a high-temperature roasting process, but the conventional method for producing raw oil takes a long time to produce raw oil due to a long drying time. There is a problem in that saturated fat or other impurities remain in the produced raw oil in various ways, and there is a problem in that a complicated process is required to remove them, and the production yield is also low and thus is not activated.

Registered Patent No. 10-1124152

The present invention has been devised to solve the above-described conventional problems, and its purpose is to provide a method and apparatus for producing raw oil that can improve the production yield without generating harmful components such as benzopyrene.

In order to achieve the above object, a device for drying perilla to produce raw oil according to the present invention is provided with a first hot air fan therein, and includes two first rollers and a second roller on both sides in a horizontal direction separated by a predetermined distance. Two rollers are installed, including a first conveyor belt that is mounted on the first roller and the second roller and rotates for a long time, and removes foreign substances by washing with water and removes debris through a centrifugal separator. A first conveyor device for conveying in a horizontal direction using a belt, drying by the first hot air fan, and dropping in a vertical direction; A second hot air fan is provided inside, and two third rollers and fourth rollers are installed on both sides in a diagonal direction separated by a predetermined distance, and a second conveyor mounted on the third roller and the fourth roller rotates for a long time. It is configured to include a belt, and is configured to include a second conveyor device that receives the perilla dropped in the vertical direction by the first conveyor device and then transports it in a diagonal direction to dry by the second hot air blower.

In addition, in order to achieve the above object, the method for producing raw perilla oil according to the present invention comprises the steps of washing perilla with water to remove foreign substances; Dehydrating the perilla washed through the above steps through a centrifuge; A step of primary mixing and drying the perilla dehydrated through the above steps at a temperature of 50 to 60 degrees Celsius in a transfer mixing barrel; Cooling the perilla dried through the above steps for 10 minutes to 20 minutes with a wind of 7 degrees to 13 degrees Celsius and drying for a second low temperature; It comprises a step of squeezing the perilla dried by the low temperature through the milking machine through the above steps.

As described above, according to the present invention, it is possible to minimize the production of harmful substances such as benzopyrene in the production of perilla oil by minimizing the situation of applying heat at a high temperature.

In particular, by using the perilla mixing drying apparatus, mixing and drying are performed when the perilla is dried, so that rapid drying is possible, and further, the milking yield can be improved.

In addition, it is possible to easily remove saturated fats or impurities generated during production of fresh oil through a storage step in the freezer.

1 is a raw oil production process according to an embodiment of the present invention,
Figure 2 is a schematic structural diagram of a perilla mixing drying apparatus according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, each embodiment according to the present invention is only one example to help understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention may be composed of a combination of at least one or more of individual components, individual functions, or individual steps included in each embodiment.

In particular, for convenience, some claims in the claims include alphabets such as'(a)', but these alphabets do not define the order of each step.

The overall production process for producing raw oil according to an embodiment of the present invention is as shown in FIG. 1.

First, the first step of washing the perilla with water to remove foreign substances (step S1).

For example, foreign substances may have been introduced during the storage of perilla seeds, or the perilla seeds may be included together. In addition, these impurities are washed with water to cleanly remove dirt and the like on the perilla seeds.

Of course, it is also possible to jet foreign substances on the periphery of the perilla or by packaging the perilla by a method such as wind or centrifugation, but it is preferable to wash with water to reliably remove fine dust and the like.

Since the perilla wraps the perilla peel contains more oil compared to the perilla peel, it is preferable to wash the perilla itself sufficiently with a low possibility of moisture permeation so that the perilla peel can be called. The so called perilla peel has the effect of allowing the perilla and sesame peel to be separated smoothly from the peeler. It is preferable to remove some water from the perilla which has been washed in this way using a plate or a screen.

Next, a second step of dehydrating the perilla which has undergone the washing process in the first step through a centrifugal separator is performed (step S2).

The centrifugal separator for dehydration may be composed of a motor that rotates the through-passage, and a myriad of holes through which water escapes may be formed on the surface of the through-passage.

The principle of dewatering using centrifugation is that when a wet object is rotated at a high speed in a centrifuge tube, the object receives a force outside the center of the cylinder due to centrifugal force, where the object stays inside the container while water is passed through the hole formed in the container This is the same as the principle of the dehydrator of the washing machine, and the dehydration method itself by the centrifugal separation principle corresponds to a known technique, so a more detailed description is omitted.

However, since the time is too long to dehydrate only the washed perilla as it is, it is possible to rapidly dehydrate it by proceeding with dehydration using this centrifugation principle.

Next, the third step of the primary mixing at a temperature of 50 to 60 degrees Celsius and drying the perilla which has been dehydrated through the second step is carried out in a transfer mixing barrel (step S3).

Even if dehydration was performed in a centrifugal separation step in the second step, a drying process is essential in order to produce perilla oil by milking perilla. In the present embodiment, in some cases, a natural drying method that is left for several days is used. The drying process includes the process of mixing hot air and perilla.

This is to shorten the drying time to the maximum since it may take a long time (for example, about a week) to allow natural drying as in the conventional method.

Specifically, the primary mixing and drying step (the third step) is a step of transporting and drying the dehydrated perilla through the first conveyor device 110 equipped with a hot air blower and dropping it vertically (step 3-1). ), and similarly, after receiving the perilla dropped in the previous step through the second conveyor device 120 equipped with a hot air blower therein, it may be made to include a step of raising and transporting in a diagonal direction (step 3-2). .

That is, in step 3-1, the perilla is placed on the belt (aka'first conveyor belt 111') of the first conveyor device 110 and then dried while being moved, in this case, inside the first conveyor device 110, that is, , A heat source (for example, hot air) for drying exists in an inner center where the belt of the first conveyor device 110 is rotated for a long time, and when the belt of the first conveyor device 110 moves over the heat source, perilla is placed thereon. Is drying by the heat source below.

The perilla which was dried while being transported on the belt of the first conveyor device 110 falls vertically at the end of the belt, because the belt of the first conveyor device 110 is configured to rotate long.

That is, in a position in which the belt of the first conveyor device 110 moving in the horizontal direction faces downward, the perilla placed on the belt of the first conveyor device 110 falls to the lower air hole.

At this time, the perilla falling in the vertical direction is seated on a belt (also,'second conveyor belt 121') of another second conveyor device 120, and then additional drying is performed while moving.

That is, inside the second conveyor device 120, that is, the second conveyor device 120, the inner center where the belt rotates for a long time, as in the first conveyor device 110 described above, a heat source (for example, hot air) for drying perilla is provided. Existing, when the belt of the second conveyor device 120 moves over this heat source, the perilla on it is further dried by the heat source below.

At this time, the second conveyor device 120 receives the vertically dropped perilla from the belt of the first conveyor device 110, and then raises it in a diagonal direction to transport and dry it.

That is, the belt of the second conveyor device 120 may be configured to rotate long in the diagonal direction, wherein the lower part receiving the dropped canopy is gradually moving upward in the diagonal direction, and additional drying is performed during the movement. .

As such, after drying the perilla through the first conveyor device 110, it is dropped to the second conveyor device 120 by a falling motion, thereby achieving the effect of mixing the perilla.

In other words, when the perilla is mixed by this dropping method, the perilla perilla may be mixed, but the perilla kernel itself changes up and down or left and right, and eventually becomes evenly dried, which has an excellent effect, which greatly affects perilla oil production yield. Corresponds to the factor.

For reference, FIG. 2 shows a simple structural diagram of the perilla mixing drying apparatus 100. In this embodiment, a description and description of parts that can be sufficiently understood and expected by those skilled in the art will be omitted, and the characteristic parts will be mainly described.

As shown in this figure, the perilla mixing drying apparatus 100 may include a first conveyor apparatus 110 and a second conveyor apparatus 120.

Here, the first conveyor device 110 includes a first hot air fan 114, a first roller 112, a second roller 113, a first conveyor belt 111, and a first roller 112 and a second roller It may be configured to include a first motor 115 and the second motor 116 to rotate (113), respectively.

Here, the first hot air fan 114 is a device that applies heat to dry the perilla 200 moving on the first conveyor belt, and may be replaced with another heat source that can heat the perilla 200 instead of the hot air fan. Of course.

The first hot air fan 114 is preferably located in the inner center of the first conveyor device 110, as shown in the figure.

The first roller 112 and the second roller 113 are provided in both horizontal directions separated by a predetermined distance, and the first conveyor belt 111 moves in combination with the first conveyor belt 111 as described later. It performs the function to do. Since the coupling structure of the conveyor belt and the roller itself is a well-known technique, a more detailed description is omitted.

The first conveyor belt 111 is configured to be moved and rotated in combination with the first roller 112 and the second roller 113 as described above.

The first motor 115 and the second motor 116 are responsible for the rotational motion of the first roller 112 and the second roller 113, respectively, and the number of motors can be any number through structural changes.

The first roller 112 and the second roller 113 rotate through the rotation operation of the first motor 115 and the second motor 116 so that the first conveyor belt 111 moves in a horizontal direction, Accordingly, the perilla 200 placed on the first conveyor belt 111 is dried by the first hot air fan 114 while moving horizontally (left to right), and the end point of the first conveyor belt 111 (bending downward) ) In the downward direction.

Meanwhile, the second conveyor device 120 includes a second hot air fan 124, a third roller 122, a fourth roller 123, a second conveyor belt 121, and a third motor 125 and a fourth motor. It can be configured to include 126.

Here, the second hot air blower 124 is a device that applies heat to dry the perilla 200 moving on the second conveyor belt, and may be replaced with another heat source that can heat the perilla instead of the hot air blower. .

The second hot air fan 124 is preferably located in the inner center of the second conveyor device 120, as shown in the figure.

The third roller 122 and the fourth roller 123 are located on both sides in a diagonal direction separated by a predetermined distance, and the second conveyor belt 121 moves in combination with the second conveyor belt 121 as described later. It performs the function to do. Since the coupling structure of the conveyor belt and the roller itself is a well-known technique, a more detailed description is omitted.

The second conveyor belt 121 is configured to move and rotate for a long time in combination with the third roller 122 and the fourth roller 123 as described above.

The third motor 125 and the fourth motor 126 are responsible for the rotational movement of the third roller 122 and the fourth roller 123, respectively, and the number of motors can be any number through structural changes.

Through the rotation operation of the third motor 125 and the fourth motor 126, while the third roller 122 and the fourth roller 123 rotate, the second conveyor belt 121 moves upward in a diagonal direction. , Accordingly, the perilla 200 placed on the second conveyor belt 121 is dried by the second hot air fan 124 while moving upward in the diagonal direction, and the end point of the second conveyor belt 121 (the point bent downward) You will fall down and prepare for the next step.

Next, the fourth step of performing the second low-temperature drying is performed by cooling the dried perilla seeds through the third step with a wind of 7 to 13 degrees Celsius for 10 to 20 minutes (step S4).

This is to increase the yield of perilla oil by ensuring the degree of drying of perilla dried by a heat source such as hot air.

In other words, when cooling at a low temperature for 10 to 20 minutes with a wind of 7 to 13 degrees Celsius corresponding to a cool dry wind, an effect of reliably removing moisture remaining in the perilla occurs, thereby increasing the perilla oil yield. do.

Next, a fifth step of pressing and milking the perilla dried at a low temperature through the fourth step through a milking machine is performed (step S5).

For example, the perilla dried at low temperature through the fourth step is placed in a milking machine composed of two sauds, a spoon, a bottom plate, and a cylinder (6.5 kg to 8.5 kg), and compressed for 15 to 25 minutes at a pressure of 550 Kgf to 650 kgf. So you can milk raw oil.

The technique of extracting oil from grains of grain by pressure corresponds to a known technique, so a more detailed description is omitted.

Thereafter, the raw oil milked through the fifth step is stored and stored in a freezer having a temperature of -3 degrees Celsius to 0 degrees Celsius for 2 days to 5 days to perform a sixth step of solidifying impurities containing saturated fat (step S6). ).

In the case of raw oil milked according to the present embodiment, impurities such as saturated fats that are partially aggregated are generated when stored at 10 degrees, but even if filtered, another saturated fat and impurities are found at 5 degrees, similarly Even if it is filtered out, another saturated fat, etc. can be found when stored at 0 degrees.

Therefore, when stored in a freezer at a temperature of 3 to 0 degrees Celsius (2 days to 5 days) below zero, all kinds of impurities such as saturated fat appear in a solidified form.

Therefore, after passing through the sixth step, by proceeding with the seventh step of filtering the filter oil by applying pressure from the filter press (step S7), the final solidified oil can be produced.

In addition, the present invention is not limited to the specific embodiments described above, but can be implemented by modifying and modifying in various ways without departing from the gist of the present invention. It will be apparent that such variations and modifications are included in the present invention if they fall within the scope of the appended claims.
