How to make powder of Pueraria Mirifica

Cleaning tuber: select the smooth surface, no mold, no broken kudzu root with water to wash away dirt, sand and other impurities, no need to remove the skin.

Crushing and milling: send the cleaned kudzu root pieces into the crushing machine for crushing. Water must be added when crushing, and the ratio of kudzu and water is 1:3. The aperture of the sieve of the crusher is 2 millimeters.

Separation of slurry and residue: choose a clean pool, with a wide plastic sheet padding, and then the 90-100 mesh wire sieve placed in the pool. In the sieve laid on gauze, the end of the slurry samples on the gauze, injected into the water, fully stirred, so that the starch with the water leakage into the pool, repeatedly adding water until the starch and powder slag separation clean. Conditions can also be separated by centrifuge, centrifuge speed of 1000 revolutions per minute, centrifugation for 10 minutes that is the wet starch.

Sedimentation: the starch slurry will be precipitated for 48 hours after scooping dry starch above the water, remove the starch block.

Drying: the starch blocks can be packaged after drying in the sun. Due to the process of drying in the sun, starch will occur to a certain degree of oxidative decomposition, so it is recommended to dry starch. Drying temperature of about 60 ℃ is appropriate.
