sweet potatoes, sweet potato press, cloth, glass jar, funnel, long chopsticks, bamboo poles, etc.

wash a large number of sweet potatoes, rinse with water several times, so as not to have the sand attached to the skin of the sweet potatoes; rinsed sweet potatoes into the sweet potato machine, sweet potatoes squeezed into the crush.

The crushed sweet potato with a cloth sieve out residue, cloth placed under a large square wooden barrel to load the cloth leaking down the water; sieve well after the barrel will be left to stand for 12 hours, the purpose is to let the sweet potato flour precipitation; 12 hours after the barrel is poured out, add the right amount of clean water, the purpose is to remove impurities, so that the interval of a few hours to do this repeatedly.

Then after 1 day, pour out the water, fish out the sweet potato flour pieces, wrapped in a hemisphere with the previous cloth (as shown in the picture below), to drip out the excess water.

Until the hemispherical sweet potato is not dripping, has been relatively dry from the cloth out of the glass bottle into a powder, it can be used to make vermicelli after drying!

Pour sweet potato flour into the vat, add the right amount of hot water to make a paste, and then use boiling water while stirring. About 18 minutes, the powder paste was transparent and uniform, easy to produce silk that is the powder. Add 0.5% alum in the powder, and then mix with wet starch, kneaded into no lumps, non-sticky, can pull, uniform and delicate soft dough.

Put the seasoned dough into the funnel (set at about 40 cm from the water surface of the water pot), and then evenly pat the dough, so that it becomes a strip from the funnel into the water pot, and meet the heat solidification that is made into vermicelli. The water is boiling but not boiling (the water temperature is maintained at about 97 ℃) to ensure that the vermicelli is not easy to break.

In the hot water pot placed next to a cold water tank, vermicelli molding from the hot water pot with long chopsticks clamped to the cold water tank, vermicelli cooled some fish out, wrapped around a bamboo pole into a bundle and put away.

Finally, the vermicelli will be placed on a long bamboo pole, and the wet vermicelli one by one after the separation of the sun in the sun (so that the vermicelli can dry faster), the sun is big in the case of the sun 3-4 days can be fully dry, you can collect the vermicelli bagged.
