Use 5 kilograms of mung beans (or soybeans) (5 kilograms is used as the standard here, and the amount can be increased or decreased according to the proportion). First, wash the mung beans twice with clean water, then soak them in warm water, and wait for the mung beans to swell. After that, put it in a wooden barrel and cover it with three or four layers of cloth. Sprinkle 11 pounds of water every 5 hours on the first day, 20 pounds of water every 4 hours on the second day, and on the third day when the bean sprouts have grown to about half an inch long, you need to check the temperature in the bucket at any time. Just try it with your hands. If there is a feeling of warmth, you need to sprinkle 40 pounds of water until the bean sprouts grow to 1 inch long. In this way, 5 pounds of mung bean sprouts can produce about 50 pounds of fresh and tender bean sprouts.

It should be noted that mung bean sprouts should be selected with full seeds; the water sprinkled should be clean; the cloth and wooden bucket covered should be scrubbed clean; the bean sprout bucket should be placed in a place with good air circulation, but not allowed to The bean sprouts should be exposed to the sun to prevent them from turning green and getting old; you should always pay attention to the growth of the bean sprouts, do not let the bucket be too cold or too hot, and sprinkle water evenly and timely so that the bean sprouts can grow quickly and well.

The standards here seem to be a bit too high. If you are not planning to sell bean sprouts but are eating them yourself, it would be best to reduce the amount of beans to 50 or 100 grams. The amount of water sprinkled is also reduced proportionally. But the time required is the same! I wish you can eat bean sprouts as soon as possible. . . .

Considering that you may not have a wooden bucket, just find a leaky container (such as a plastic bucket or something), put a straw mat or thick towel at the bottom, pick out the beans and soak them in water, and soak them in hot weather Soak for 6-8 hours, or about 20 hours in cold weather, so that the skin of the beans becomes plump and a little cracked, then put it in a container, cover it with a towel and place it in a dark place. Keep warm in winter and avoid wind in summer.

For other steps, refer to the above method. On cold days, pour warm water and let the water drain off the towel.

When the weather is hot, it is suitable to hatch mung bean sprouts, and when it is cold, it is suitable to hatch soybean sprouts.
