It relates to a method of manufacturing perilla oil by a cold pressing milking method, characterized in that.

Hereinafter, the background art will be described with reference to the accompanying drawings.

As is well known, perilla oil is an oil obtained by squeezing the seeds of perilla and is a kind of dry oil, and when perilla seeds are squeezed, about 35-45% of perilla oil can be obtained.

This perilla oil is one of the high-grade oils and contains a lot of unsaturated fatty acids.It contains about 50-60% of alpha-linolenic acid (ALA), an omega-3 fatty acid, and is mainly used for medicinal, flavoring, and food. There are a lot of unsaturated fatty acids, and it quickly spawns in the air column, so it should be prevented from contacting the air during storage.

In addition, in order to increase the extraction efficiency when extracting oil from the perilla seed, a stir-fry method is mainly used.

The stir heat compression method is a method that has been traditionally used when extracting oil from the seeds of plants, and is extracted through the order of washing-stir-combustion-thermal compression milking-natural sedimentation. Stir-fry and milk.

However, in the case of perilla oil, since the smoke point is 202℃, when the oil reaches this temperature during the roasting process, the unsaturated fatty acids are destroyed as the oil is incompletely burned, thereby producing benzopyrene, a primary carcinogen, and that is unsaturated. Fatty acid is reduced, which is inevitable to the human body.

Accordingly, recently, a cold pressed method of extracting oil without a roasting process has been disclosed. When the perilla is cold pressed without heating, the friction heat generated by the perilla itself does not usually exceed 49°C. The method of extraction while maintaining the following is usually called cold pressing, that is, cold pressing, and this method has no production of benzopyrene because the unsaturated fatty acids are not destroyed, and maintains the unique aroma of perilla seeds, and also has a low acid value, which makes perilla oil long-term. It can be stored, so its utilization is high.

However, when cold compressing perilla, the larger the particle size of the perilla must be, the colder the perilla must be cold pressed. The greater the particle size of the perilla during cold pressing at the same pressure, the smaller the amount of perilla oil to be milked.

In addition, in general, it takes too much time to dry the perilla before it is cold pressed before drying, and when drying with hot air, the drying time is shortened, but in addition to the perilla stripper, a separate hot air blower is provided and the perilla stripping operation and There is a problem in that hot air drying must be performed separately.

According to this configuration, perilla is sterilized by washing with magnetized water, and at the same time, it is possible to wash perilla with only magnetized water without detergent. In addition, cloisonne water has a sterilizing effect because it activates water molecules. The perilla toxin is neutralized and has the effect of slowing down deterioration.

The natural drying step (S3) is a step of naturally drying the washed perilla.

As shown in FIG. 4, the perilla peeling and discharging step (S4) includes a hopper 10 for introducing perilla, a supply roller 20 for peeling the shell of the perilla, and a peeling roller 30, and By using a perilla stripper including a hot air blower (40) for transferring the peeled perilla peel to the hot air and a discharge duct (50) for discharging the transferred perilla shell to the outside, the dried perilla peel is peeled off It is discharged to the outside of the perilla peeler. The perilla injected through the hopper 10 passes through the space between the supply roller 20 and the peeling roller 30 and moves downwards to form stripping and flows down to enter the discharge duct 50 and the particles of the discharge duct 50 The perilla kernels are discharged through the outlet 502. At this time, as the stripping is performed, when the perilla shell enters into the discharge duct 50 and falls downward, the hot air blower 40 operates to supply hot air through the exhaust port 40b of the hot air blower 40. The perilla shell moves upward through the passage in the discharge duct 50 and is discharged to the outside through the shell outlet 501.

Next to the skinning roller 30, a plurality of (eg, 2 to 3) different skinning rollers 30 may be installed adjacent to each other and guided to the discharge duct 50 due to the installation of these different skinning rollers 30. It is also possible to configure the perilla to pass through the inclined guide plate so that the peel of the remaining perilla is still unpeeled. According to this configuration, the perilla peel can be completely removed.

The peeling roller 30 has an embossed surface, so it is also possible to facilitate the peeling of the perilla. According to this configuration, the peeling of the perilla is facilitated.

Referring to FIG. 5, the discharge duct 5 has an S-shaped cross-section, but is zigzag, and the angles of the bent parts are configured to form an obtuse angle, so that the hot air supplied when the hot air blower 40 is operated and this hot air It is accompanied by relatively smooth movement of the perilla shell discharged to the outside. However, the discharge duct 5 has an S-shaped cross section but is configured to form a surface having a smooth curve inside without a zigzag section, and is supplied with the hot air supplied during the operation of the hot air blower 40 and the hot air. It is also possible to facilitate the movement of the perilla peel that is discharged.

Here, as shown in FIG. 4, the intake port 40a of the hot air blower 40 is installed to penetrate the rotation shaft 401 so as to pass through the rotation shaft 401, and the fixing block 401a is attached to one end of the rotation shaft 401 exposed outside the intake port 40a. In the installation, a support 403 is installed on one side of the hot air blower 40 to connect the wire 70 between the support 401a and the adjustment handle 60 so that the support 403 penetrates. In addition, by winding the wire 70 using the adjustment handle 60 installed on the outer surface of the main body by installing the coil spring 404 between the support 403 and the fixture 401a, the fixture 401a installed on the rotating shaft 401 And the wire 70 connected between the adjustment handle 60 installed on the outer surface of the main body is pulled, the rotating shaft 401 is rotated so that the fixture 401a comes close to the support 403, whereby the coil spring is compressed and at the same time the intake port As the opening/closing door 402 installed in (40a) is closed, the passage of the intake port (40a) is narrowed, thereby reducing the amount of air flowing into the blower (40), thereby reducing the air pressure discharged to the exhaust port (40b) of the blower (40).
