The common method of making bean sprouts is the most primitive method of making bean sprouts with clear water. The production of bean sprouts only uses mung beans and water, and does not use additives harmful to human health. Clear water produces beans, and a catty of soybeans can produce about three kilograms. 1 catty of mung beans can produce up to 8 kilograms of bean sprouts. It takes 5 to 7 days from soaking beans to bean sprouts.
The length of bean sprouts sold in general vegetable markets is around 10 cm. One kilogram of soybean can produce about 10 kg of bean sprouts, and the yield is stable. In other words, it only takes 100 kg of soybeans to plant 100 kg of soybean sprouts. The wholesale price of a kilo of soybean is not higher than that of 4 yuan, which means that the cost of selling 1000 kilo of bean sprouts a day is less than that of 400 yuan. Soybeans can grow bean sprouts as long as they are wet every day. Generally, as long as there is 1.5 ~ 2 square meters in any corner of the house, you can produce 300 ~ 400 kilograms of bean sprouts at a time. One kilogram of mung bean can produce 10 ~ 12 kilograms of bean sprouts (without additives), and the production cycle of bean sprouts is about 5 ~ 7 days. Take 1 kg soybean as an example: 1 kg bean sprouts can be sold for 3 yuan in the market, while the cost of producing bean sprouts is generally about 2 yuan 1 kg. Of course, the actual situation varies from place to place, and this value is different, which is for reference only. The actual cost and profit of producing bean sprouts shall be subject to reality.
2.5 yuan gave seven kilos of mung beans to one kilo, and 2 yuan sold one kilo, and the profit was 7*2-2.5= 1 1.5 yuan.
