Description

{Apparatus for removing agricultural chemicals remaining in the roots of medicinal plants}

The present invention relates to a cleaning device, and in detail, to a device for removing pesticide residues of a medicinal root that can effectively remove residual pesticides and harmful substances without damaging the fine roots by applying a microbial fermentation method while washing various medicinal roots represented by ginseng. will be.

In general, when growing most agricultural products, various pesticides or fertilizers are sprayed to prevent pests and promote growth, so some pesticides and fertilizer components remain on the surface of harvested agricultural products, and are contaminated with heavy metals through various routes and come to our table. .

Due to the dangers of heavy metals and pesticides, the government (Ministry of Food and Drug Safety) is pursuing a PLS (Positive List System) system, and plans to actively crack down on residual pesticide components in agricultural products distributed through the transition period.

As a result, pesticide-free and organic cultivation techniques are emerging, but in most farms that cannot be applied immediately, it is difficult to cultivate and harvest crops without using pesticides.Therefore, there is a burden from PLS in many farms, and residual pesticides are present in imported agricultural products. If the standard value is exceeded, the customs clearance itself is not possible and is returned or disposed of, so countermeasures against residual pesticides are required.

Conventionally, such residual pesticides were removed through manual washing, but large restaurants and cafeterias require considerable time and manpower due to the large amount of water to be washed.Some cases where residual pesticides cannot be completely removed during this process. there was.

In particular, unlike fruits and vegetables that have a smooth surface, the roots are not only difficult to clean because they require more detailed cleaning, and in particular, various medicinal herbs represented by ginseng have hydrophilic formation of roots and fine roots to remove residual foreign substances between them. It was not easy, and in the process of rubbing or rubbing them with a brush in a situation where the shape and size are not constant, damage to the fine roots was bound to occur.

Due to the peculiarity of washing the roots of these drugs, various exclusive washing devices are being developed, but the fine roots are still cut due to the contact between the brush and the roots, and the marketability of relatively expensive medicinal materials such as ginseng is greatly degraded, leading to a decline in profits for farmers. .

In addition, in a conventional washing machine, washing water including residual pesticides is discharged to the outside with foreign substances as it is, so it has also become a cause of water pollution.
