Method for removing harmful components of cashew nut extract and screw conveyor for size control and wear response for centrifugal separation

摘要

The present invention relates to a method for removing harmful components from a cashew nut endothelial extract, and a screw conveyor capable of adjusting the size for centrifugation therefor and responding to abrasion, and more particularly, of a cashew nut wrapped with an inner shell and an outer shell of the seed. In the process of obtaining a blood extract using either the endothelium and the outer skin, or one of these, Cadenolid, which has a very strong toxicity, is removed to make it usable for edible use. In the process of phase centrifugation, the screw conveyor can be reinforced to be used, and the size (diameter) of the worn screw conveyor is adjusted to respond to abrasion, and a method of removing harmful components from cashew nut extract to ensure stable use while reinforcing for a long time. It relates to a screw conveyor capable of adjusting the size for centrifugation and responding to wear. The present invention includes a first step of obtaining blood by removing both the outer skin and the inner skin of the cashew nut or any one of the blood; After dissolving the obtained outer skin and inner skin or the blood consisting of any one of them in an organic solvent consisting of ethanol, methanol, acetone, or chloroform, it was filtered and put in a hot air dryer and dried for 3 to 24 hours at a temperature of 100 to 400°C. A second step of primarily removing toxicity; The third step of removing toxicity by adding and dissolving the dry skin and the inner skin or the blood consisting of any one of them in an organic solvent such as ethanol, methanol, acetone, chloroform, etc. in a ratio of 1 to 10% (v/w). ; A fourth step of supplying the dissolved outer skin and the inner skin or blood composed of any one of them to the extraction device so that the blood extract is discharged by pressure; A fifth step of evaporating and drying the extracted blood extract at a temperature of 50 to 90°C using a vacuum evaporator after filtering until the solvent is completely removed; A sixth step of diluting the evaporated and dried seed bark extract at a weight ratio of 50 to 2,000 times using water or an organic solvent; A seventh step of evaporating and concentrating the diluted blood extract, diluting by adding three times the amount of distilled water, and then separating antioxidants and anticancer substances using an anion, cation exchange resin, silica or ODS column as a reverse phase column; Including, A hollow is formed in the inner diameter of the cylindrical rotating shaft and the screw blade is formed in a spiral shape on the outer diameter of the space on the right side to rotate in the inner diameter of the bucket to separate the supplied extract into sludge, heavy liquid and hard liquid; The screw blade part forms installation holes at regular intervals, and the size adjustment reinforcing blades in which fixing holes are formed at regular intervals on one side of the screw blade part are combined to adjust the size of fixing bolts and fixing nuts at the installation holes and fixing holes. Device; In the screw conveyor comprising a reinforcing member formed on the size-adjustable reinforcing blade and provided with a locking fixing protrusion formed with a locking fixing groove surrounding the outer diameter tip of the screw blade, The size adjustment reinforcing blade is formed to protrude further to the outer diameter of the screw blade and protrude to the outer diameter along the outer diameter tip and then protrude a reinforcing protrusion to one side so that the bent shape becomes "a" shape so that the wear of the tip is slow to respond. Including, It is formed to have an angle of 45 to 90° and is fixed to the screw blade in the form of a screw, and an inner groove is formed in the inner diameter to be fixed along the outer diameter of the rotating shaft, The reinforcing member protrudes so that the locking protrusion formed with the locking groove surrounding the outer diameter tip of the screw blade is integrally formed in a "" type, and the outer diameter reinforcing rod is formed between the reinforcing protrusion outside the locking protrusion. It is characterized by.
