Description

Apparatus for extracting white starch from kudzu and extracting method thereof}

The present invention relates to an apparatus for extracting white arrowroot starch and a method for extracting white arrowroot starch using the same. In particular, since it contains medicinal ingredients including starch and has a lot of fiber like arrowroot (hereinafter referred to as 'arrowroot'), it is crushed or crushed and then compressed. Thus, starch can be easily and quickly extracted in high yield from plants from which sap (juice) can be obtained.

As the number of raw or natural diets using kudzu or fruit has increased, crushers for extracting juice or liquid have been provided so that they can be extracted into juice or liquid for drinking.

However, since it was difficult to supply and crush plants having tightly formed fibers such as kudzu without cutting them to a predetermined size, a crusher capable of crushing them by supplying them without cutting them was devised.

Plants shredded through a crusher are squeezed using a hydraulic machine to obtain fresh juice, and this juice undergoes a precipitation process to remove impurities and starch (starch) contained in the juice to enhance the taste and texture of the drinker. . This precipitation process is a process of separating the sap from the solids by stabilizing the raw juice for a certain period of time in order to take only the sap part.

Figure 2 briefly shows the arrowroot juice extraction process according to the prior art. Referring to Figure 2, the arrowroot juice extraction process is described. After crushing, it is put in a press (2) to extract arrowroot juice using hydraulic pressure. Since starch of about 10% of the starch contained in arrowroot is extracted together with the extracted arrowroot juice, the extracted arrowroot juice is transferred to the settling unit 3 to separate starch and starch-free arrowroot juice. The starch-free arrowroot juice is transferred to a sterilizer (7) and heated to an appropriate temperature to remove germs that may be contained in the raw juice, as well as remove miscellaneous odors, and then mature for a certain period of time to adjust the taste and aroma, and then add additives such as honey After adding an appropriate amount, it is packaged in a pouch or bottle.

On the other hand, the starch separated from the precipitation unit 3 is dried through a dryer 4, powdered in a grinder 5, and then packaged. At this time, since the initial starch separated from the settling unit 3 has a unique black color of kudzu, it does not suit the general consumer's taste, so pour water, rinse and precipitate, and then perform a rinsing process of discarding the upper water several times. When it becomes white starch, it is sent to the dryer (4).

Starch obtained as a by-product in the above-mentioned arrowroot juice extraction process is white arrowroot starch containing useful components of arrowroot, and as consumers' tendency to avoid modified starch has increased, the consumption of white arrowroot starch has increased significantly. It is a trend.

Accordingly, not only in the arrowroot juice extraction process, but also in extracting fresh juice from various healthy plants, the starch obtained as a by-product during the juice extraction process in the prior art is smoothly extracted and the yield is only about 10%. A method for extracting white arrowroot starch in a high yield and convenient way is urgently required.
