I come from Loudi, Hunan, and there are few handmade sweet potato fans in my hometown at present. Because farmers make vermicelli by hand at home, the destination, sanitary conditions and temperature conditions are basically processed by factories. Now the processing method of vermicelli factory is the same as that of manual vermicelli in the past, except that the machine replaces the previous labor. So fans have the same taste. Moreover, factory processing has more advantages in sanitary conditions.
At present, the good sweet potato fans in Loudi are fifteen or six yuan a catty, and Loudi, Hunan is rich in sweet potato fans. You can measure it. I hope I can help you.
