How much can't I buy lotus root starch?

How can I put it? We are from Shaoxing, Zhejiang, not a lotus root producing area, so the price of lotus root will be slightly higher. Lotus root also has different flour yield. Like we often make lotus root starch, a good lotus root starch of 100 kg can produce 9- 10 kg, and a poor lotus root starch of 100 kg can produce 5-7 kg, so the cost is high. In Shaoxing, lotus roots are all brought in from the outside. General lotus root price 130 yuan, lotus root processing fee 15 yuan, and water fee. Regardless of the cost of 100 kg, the average lotus root is 8 kg of lotus root powder, which means that the cost of 150 yuan can produce 8 kg of lotus root. 100 kg lotus root is shredded, washed for at least a few hours, and then processed into pulp, which needs precipitation and rinsing. Lotus root powder should be scraped and dried after rinsing, which is a day's work. That is to say, the cost price of pure lotus root starch is around a kilo in 20 yuan. If it is artificial, people who sell a kilo of lotus root starch in 30 yuan earn a little artificial money. But in the lotus root producing area, the cost will be reduced, but it is basically impossible to buy anything below 30 yuan.
