3 is a view showing an extraction apparatus of the present invention. Referring to Figure 3, the perforated basket 12 is suspended by the electric hoist 13 to the upper H beam 14 to enter the inside of the extraction tank 11, the electric hoist 13 is an H beam ( While moving horizontally along 14), the perforated basket 12 is vertically moved.

The perforated basket 12 is locked into the extraction tank 11 containing the solvent, the perforated basket 12 contains the raw side. Raw side of July and August, before the flowering plants, using the part except the root, and put about 2 tons into the perforated basket (12). The perforated basket 12 is formed with a plurality of holes, so that the solvent can enter the inside.

The extraction tank 11 is designed on a 10-ton scale, so that the perforated basket 12 loaded with 2 tons of raw materials is immersed in the extraction tank 11 containing 8 tons of solvent. Water is used as the solvent. Since the raw material rises when the perforated basket 12 is contained in the extraction tank 11, it is preferable to provide a lid.

When the raw side of the perforated basket 12 is immersed in the solvent of the extraction tank 11, it is necessary to maintain an appropriate temperature and supply oxygen. To this end, a boiler 17 and an air compressor 16a are provided. After measuring the temperature in the extraction tank 11 by the temperature sensor 15, steam or water is supplied from the boiler 17 to the pipe installed in the extraction tank 11 so as to maintain 30-35 degreeC. In addition, the air contained in the air tank 16b is supplied into the extraction tank 11 to supply oxygen to the solvent. It is preferable to provide the air tank 16b and the air filter 16c for stable oxygen supply.

The fresh side immersed in the extraction tank 11 is maintained at about 30 to 35 degrees Celsius for about 48 hours, and when oxygen is supplied, the color of the water, which is a solvent, changes from light green to cyan and the pigment starts to separate from the plant. At this time, the indican glycoside, which is a raw material of the indigo dye, is hydrolyzed to change into a reading room, and the reading room is changed into indigo which is a pigment by contacting with oxygen.

After 48 hours, the pigments are completely separated from the plants. By-products of the extracted side plants are pulled up by using an electric hoist (13). The extract left in the extraction tank 11 is transferred to the reactor 20 along the transfer pipe 19 by the transfer pump 18. It is preferable to provide a filter so that impurities are not added when passing through the transfer pump 18 or the transfer pipe 19. This process is repeated the same after the extract is transferred to the reactor 20.

Stirring impeller 23 is rotated at 200 ~ 500 rpm, the temperature of the extract maintains about 35 ~ 100 degrees. To this end, the temperature sensor 24 measures the temperature inside the reactor 21, and supplies or cuts heat supplied from the boiler (not shown) to the inside through the inlet pipe 24a.

In addition, oxygen must be supplied inside for the oxidation reaction of the extract. In order to measure the amount of dissolved oxygen in the extract is provided with a dissolved oxygen sensor 25, thereby supplying or blocking oxygen through the inlet pipe (25a).

In addition, an additive is put into the reaction tank 21, and as an additive, slaked lime is used. Slaked lime changes the color by supplying oxygen to the extract. Slaked lime is used to smelt shells or tangerines at 1000 degrees for more than 24 hours, and then naturally oxidize them to prevent air from passing through them with the remaining heat. The slaked lime is stored in the additive tank 28a and then added into the reaction tank 21 along the transfer pipe 28b. In order to maintain the extract PH 11, by measuring the pH inside the reactor 21 through the PH sensor 28, it is determined whether or not the addition of slaked lime.

As an example, 7 to 8 tons of the extract, temperature 20 to 35 degrees Celsius, PH concentration may be calculated by the controller to calculate the calcined lime to determine whether or not to supply. Usually, 7 ~ 8 tons of 50 ~ 55kg of lime is injected. At this time, the optimum concentration of dye can be obtained.

After the addition of slaked lime, when the stirring impeller 23 continues to rotate at about 280 rpm, blue bubbles occur, and at the same time, compressed oxygen is supplied to cause an oxidation reaction.

The extract which is stirred and oxidized with hydrated lime reacts with yellowish brown <yellow red <light green <green <cyan <blue <indigo and becomes an indigo dye. After the reaction, the indigo dye is precipitated for about 1 to 2 hours, the supernatant changes to light brown, and the indigo dye sinks in the reactor 21 together with the lime. At this time, about 300-500KG of indigo dye containing moisture is produced.
