Practice steps:
Step 1, wash all the sweet potatoes.
Step 2, or cut into pieces, add clean water and put them directly into a blender and beat them into powder. (But this is so unreliable that it went on strike after two or three uses.)
Step 3, wipe the sweet potato into silk with a silk-wiping board. (There's nothing I can do about it. The blender is broken, leaving only one soymilk machine.) Add the shredded sweet potato into clear water and put it into the soymilk machine to make pulp.
Step 4, make a filter net with mosquito nets and put it on a plastic drain basket. This is a relatively large plastic basket. ) (This can separate the sweet potato paste from the remaining sweet potato residue)
Step 5: At this time, pour the sweet potato pulp water into the partition net, and when the sweet potato pulp drops almost, add clear water and stir the sweet potato pulp while pouring water. The first filtered sweet potato slurry is poured into the bucket for precipitation. Then wash it for the second time (there will be some sweet potato powder left after the first washing, so wash it again, and don't waste it). The sweet potato water washed out for the second time can be used for beating sweet potatoes.
Step 6, after three hours of precipitation (it doesn't matter if it can be precipitated for a long time in winter, but it can't be precipitated for a long time in summer because it is hot, because the sweet potato pulp will roll in hot weather, which will be very wasteful), and then the sweet potato water is poured out, and the sweet potato powder has been precipitated at this time. This is the sweet potato powder that has been precipitated.
Step 7: Dig out the sweet potato powder from the barrel and put it in a clean container (this is to be taken out for drying, and the container must be clean) and divide it into large pieces.
Step 8: Cover with a mosquito net, clamp it around (this will reduce dust entry) and put it in the sun. Sun until the sweet potato powder is dry and hard. If the weather is fine, it will take about 3 days.
Step 9: Break it into small pieces and continue to dry it. After drying the small pieces, continue to break it and dry it for a few more days as shown in the picture. When the small sweet potato powder is completely dry, it will be fine. (The whole drying time takes about 10 days. In Guangdong, the sun is basically resting for two-thirds of the time in winter, and it will take about 5 days in summer.)
In step 10, the particles of sun-dried sweet potato powder are still a little big. Crush it with a rolling pin, and you can eat it almost at home. Then put it in a bottle and eat it slowly. 1 1 kg of sweet potato only makes about11kg of sweet potato powder, probably because the machine is not delicate enough to waste a lot of sweet potato powder. It is suggested that if you want to make sweet potato powder, you should buy a good machine, so as to avoid waste.
Tips:
There is no small problem. The main thing is to have a good tool and a heart that is not afraid of hard work. The most important thing is a heart that eats food. I still suggest that you make your own sweet potato powder and lotus root powder. Most of the products sold outside are not authentic, and they are all mixed with other powders. You can eat for a whole year after a few days' hard work. In my hometown, if there is fire, sweet potato powder will be mixed with water to make a paste to achieve the effect of removing fire. The effect of drinking it when you are constipated is very significant. And sweet potato powder can be used to make all kinds of dishes and desserts. It can be used in cooking.
