Description

Method and apparatus for producing wild oils {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 without harmful substances such as benzopyrene.

Perilla frutescens (perilla frutescens) means perennial herb or its seeds, which are native to Southeast Asia and the Indian Highlands, distributed on the Korean Peninsula, South and Central China, and India, and are widely planted in Korea during the Unified Shilla Era. It is estimated to have been planted since then.

Currently, the main perilla varieties cultivated in Korea are Dongle No. 2, Namcheon Perilla, Perilla Perilla, Perilla Perilla, and Perilla Perilla, and Perilla and Sesame are strictly different species.

These perillas contain many useful ingredients and are used as medicinal crops, oilseed crops and leafy vegetables. That is, the seeds of perilla 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 the ability to learn and improve the lifespan. It is known that the seed itself is used for perilla tea and confectionery as sesame, and the oil extracted from the seed is used for food, drug addition, and industrial use.

Perilla leaves contain perilla aldehydes, limonene, and perilla ketones as vegetable essential oils, eliminating the taste and fishy smell of pork and sashimi, and the unique fragrance can make your appetite fresh. It is used as a vegetable, and the extract of perilla leaves is used as a cosmetic pigment or fragrance.

Moreover, the recent demand for perilla, one of the largest natural sources of tocopherol, has been increasing, as tocopherols are known to prevent cardiovascular disease and cancer, support immune function, and prevent and alleviate degenerative diseases associated with aging. It is increasing.

In addition, according to the agreement, the perilla nature is described as warm, non-toxic, and taste lowers sour. Also, sesame seeds make the liver smooth, and the seeds boiled porridge makes the body smooth and beautiful and has the effect of boosting energy. 'Pharmaceutical fragments' is said to help clean water (精髓, bone marrow in the ear), eliminate thirst and sea water, remove toxins in the body, and cleans the blood.

Perilla oil, which is a vegetable oil, is produced from raw perilla, and is one of the traditional cooking oils of Korea along with sesame oil. It is characterized by about 10% saturated fatty acids and 90% unsaturated fatty acids in fatty acid composition. It is the point that α-linolenic acid (C18: 3) which belongs to 3 series polyunsaturated fatty acid occupies around 60%.

Many studies have been published on the physiological function of perilla oil with high content of α-linolenic acid. Inhibiting the proliferation of artificially induced colorectal and breast cancer, improving learning ability, preventing heart disease and blood clots caused by lowering platelet aggregation ability, improving allergic constitution, etc. It is an oil that plays an important role in maintaining fatty acid balance. In addition, the perilla oil obtained by squeezing perilla at 190-210 ° C. has a unique fragrance, and the content and pattern of the fragrance component are different depending on the roasting temperature.

On the other hand, there are various methods for preparing such perilla oil by roasting perilla at a constant temperature and time and then compressing. Among them, a typical method is to roast perilla using a roaster at a high temperature and then compress and milk by extracting.

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

Polycyclic aromatic hydrocarbons (PAHs) are known as 200 derivative compounds, their carcinogenicity has been shown. Among these, benzopyrene (3,4-benzopyrene) is found to be particularly carcinogenic. Benzopyrene is a carcinogen and contains not only carbon and hydrogen but also other elements such as nitrogen, sulfur and oxygen. It has low solubility in water and is well soluble in oil. It is also produced by combustion or high temperature pyrolysis. In foods, foods that are produced during the heating process of foods are produced by incomplete combustion of carbohydrates, proteins, fats, etc., which are the main ingredients of foods, at high temperature cooking and processing of foods, especially char-grilled meats. , Benzopyrene is produced 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 pressed oils and coffee.

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

The first is to use a stirrer to stir the sesame seeds during the stir fry process, the physical impact is applied to the sesame by the rotation of the stirrer to break the sesame to form a lot of pieces. These pieces burn easily and generate benzopyrene.

Secondly, the roasting process takes place at high temperatures. Typically, the temperature of roasting sesame seeds 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.

When the perilla oil is produced by roasting perilla in this way, harmful components such as benzopyrene may occur above the reference value, thereby causing a problem of deterioration in quality.

In order to solve this problem, methods for producing raw oil without having been roasted at a high temperature have been proposed, but the conventional production method of raw oil has a problem that it takes a long time to produce raw oil due to a long drying time. In addition, there was a problem that saturated fats or other impurities remain in the produced raw oil in various ways and have to go through a complicated process to remove them, and production yield is also low and cannot be activated.

In addition, the storage step in the freezer can easily remove the saturated fat or impurities generated during the production of raw oil.

1 is a raw oil production process according to an embodiment of the present invention,
2 is a schematic structural diagram of a perilla mix 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 configurations, 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 prescribe the order of each step.

Overall production process for producing wild oil according to an embodiment of the present invention is shown in FIG.

First, the perilla is washed with water to go through the first step of removing foreign matter (step S1).

For example, foreign matter may have entered during perilla storage, or the persimmons of perilla may also be included. These impurities may be washed with water to remove dirt on perilla.

Of course, it is also possible to spray foreign matters on the skin of perilla or mixed in perilla packaging by means of wind or centrifugation, but it is preferable to wash with water to reliably remove fine dust and the like.

Perilla wrapped in perilla shells contains more oil compared to perilla shells, so it is desirable that the perilla itself be low enough to penetrate the water so that the perilla shells can be called. The so called perilla shell has the effect of allowing the sesame and the sesame shell to be separated smoothly in the stripper. The washed perilla is preferably removed to some extent by using a harvesting or harvesting net.

Next, a second step of dehydrating the perilla after the washing process of the first step through a centrifuge is carried out (step S2).

The centrifugal separator for dewatering may consist of a motor that rotates a passing barrel, which may have a myriad of holes through which water escapes.

The principle of dehydration using centrifugation is that if a wet object is rotated at high speed in a centrifuge barrel, the object is forced out of the center of the cylinder by centrifugal force. This is the same as the principle of the dehydrator of the washing machine, and the dehydration method by the centrifugal principle itself is a known technique, and thus a detailed description thereof will be omitted.

However, since it takes too much time to dehydrate the washed perilla as it is only in the net, such as by dehydration using the centrifugal principle, it is possible to proceed with rapid dehydration.

Next, proceed to the third step of the first step of drying the dehydrated perilla through the second step at a temperature of 50 degrees to 60 degrees Celsius in the transfer mixing barrel (step S3).

Although dehydration was carried out in the second step in the second step, the drying process is essentially required to produce perilla oil by milking perilla. In the present embodiment, although a natural drying method was left for several days, in the present embodiment The drying process involves 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 naturally dry like the conventional method.

In detail, the first mixing and drying step (third step) may include transporting and drying the dehydrated perilla through the first conveyor device 110 having a hot air blower therein, and dropping the dried perilla in the vertical direction (step 3-1). And, likewise, after receiving the perilla dropped in the previous step through the second conveyor device 120 having the hot air fan therein, raising it in a diagonal direction and transporting and drying it (step 3-2). .

That is, in step 3-1, the persimmon is placed on the belt of the first conveyor apparatus 110 (also known as the 'first conveyor belt 111') and dried while moving. In the inner center of which the belt of the first conveyor device 110 is rotated for a long time, a heat source (for example, hot air) for drying exists, and when the belt of the first conveyor device 110 moves on the heat source, the perilla placed on it The drying is performed by the heat source below.

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

That is, in the position where the belt of the first conveyor apparatus 110 moving in the horizontal direction is directed downward, the perilla lying on the belt of the first conveyor apparatus 110 falls in the air below.

At this time, the perilla falling in the vertical direction is seated on the belt of another second conveyor device 120 (aka, 'second conveyor belt 121'), and further drying is made while moving.

That is, a heat source (for example, hot air) for drying perilla is provided in the second conveyor apparatus 120, that is, in the inner center where the belt of the second conveyor apparatus 120 is rotated for a long time, as in the first conveyor apparatus 110 described above. When the belt of the second conveyor device 120 is moved on the heat source, the perilla placed on it is further dried by the heat source below.

In this case, the second conveyor apparatus 120 receives the perilla falling vertically from the belt of the first conveyor apparatus 110 and then transports and lifts it in the diagonal direction.

That is, the belt of the second conveyor apparatus 120 may be configured to rotate in a diagonal direction, wherein the lower part receiving the dropped wild dog is gradually moved upward in the diagonal direction, and further drying is performed during the movement. .

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

In other words, when perilla is mixed by such a drop method, perilla may be mixed, but the perilla grain itself may be changed up and down or left and right, and eventually it may be evenly dried, which may greatly affect the yield of perilla oil. Corresponds to the factor.

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

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

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

Here, the first hot air fan 114 is a device for applying heat for drying the perilla 200 moving on the first conveyor belt, and may be replaced with another heat source capable of applying heat to the perilla wire 200 instead of the hot air fan. Of course.

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

The first roller 112 and the second roller 113 are provided on both sides of the horizontal direction apart from a predetermined distance, and as will be described later, the first conveyor belt 111 moves in combination with the first conveyor belt 111. Perform the function to make it work. Since the coupling structure of the conveyor belt and the roller itself corresponds to a known technique, a detailed description thereof will be omitted.

As described above, the first conveyor belt 111 is coupled to the first roller 112 and the second roller 113 to be configured to move and rotate long.

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

The first conveyor belt 111 is moved in the horizontal direction while the first roller 112 and the second roller 113 are rotated through the rotation operation of the first motor 115 and the second motor 116. Accordingly, the perilla 200 placed on the first conveyor belt 111 is dried by the first hot air fan 114 while moving horizontally (from left to right), and ends of the first conveyor belt 111 (folded downwards). ) Will fall down.

Meanwhile, the second conveyor apparatus 120 includes the second hot air blower 124, the third roller 122, the fourth roller 123, the second conveyor belt 121, the third motor 125, and the fourth motor. And 126.

Here, the second hot air fan 124 is a device for applying heat for drying the perilla 200 moving on the second conveyor belt, and may be replaced with another heat source that can heat the perilla in place of the hot air fan. .

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

The third roller 122 and the fourth roller 123 are located on both sides of the diagonal direction at a predetermined distance apart, and as described later, the second roller belt 121 is moved in combination with the second conveyor belt 121. Perform the function to make it work. Since the coupling structure of the conveyor belt and the roller itself corresponds to a known technique, a detailed description thereof will be omitted.

As described above, the second conveyor belt 121 is coupled to the third roller 122 and the fourth roller 123 to be configured to move and rotate long.

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, the number of the motor can be any number through a structural change.

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

Next, the fourth step of performing a second low temperature drying while cooling the dried perilla mixed in a third step for 10 minutes to 20 minutes with a wind of 7 degrees to 13 degrees Celsius (step S4).

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

In other words, when cooled at a low temperature for 10 to 20 minutes with a wind of 7 degrees to 13 degrees Celsius, which corresponds to a cool dry wind, the water remaining in the perilla is reliably removed, thereby increasing the yield of perilla oil. do.

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

For example, the cold dried perilla in the fourth step is placed in a milking machine consisting of two saoud, upper spoon, bottom plate, cylinder (6.5kg to 8.5kg), and compressed for 15 to 25 minutes at a pressure of 550kgf to 650kgf. You can milk raw oil.

The technique of extracting oil from grains by pressure corresponds to a known technique, and thus a detailed description thereof will be omitted.

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

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

Therefore, when stored in the freezer (2 days to 5 days) at a temperature of minus 3 to 0 degrees Celsius lower than this, impurities such as saturated fats of all kinds appear to be solidified.

Therefore, after passing through the sixth step, by performing a seventh step (step S7) of applying the pressure in the filter press the raw oil is solidified impurities (step S7), the final high-quality raw oil can be produced.

In addition, this invention is not limited to the above-mentioned specific Example, It can implement in a various deformation | transformation and correction within the range which does not deviate from the summary of this invention. It will be apparent that such variations and modifications are included in the present invention as long as they belong to the appended claims.
