the fourth step: drying fresh leaves of potato tips
Placing the fresh potato tip leaves subjected to freeze-drying and wall breaking on an iron tray and drying in a drying chamber;
turning over the fresh potato tip leaves in the dryer every half hour to accelerate the drying speed of the fresh potato tip leaves;
and (4) taking out the iron tray when the moisture in the fresh potato tip leaves reaches 1%, so that the moisture in the fresh potato tip leaves is locked at 1%.
Preferably, the ratio of water to salt in the brine is 100: 1, soaking fresh potato tip leaves in saline for 20 minutes.
Preferably, the time for washing the fresh potato tip leaves by the long running water in the water pool is 15 minutes, and the fresh potato tip leaves are turned over once every 5 minutes.
Preferably, the prefreezing treatment freezes fresh leaves of the potato tips to 10-20 ℃ below the freezing point, and the time of the main freeze-drying treatment is four hours.
Preferably, the ultrafine powder agent with the size of 80 meshes is formed after freeze-drying and wall breaking of the fresh leaves of the potato tips, and the weight ratio of the fresh leaves of the potato tips is 20: 1, performing freeze-drying and wall breaking treatment.
Preferably, the fresh potato tip leaves are dried in vacuum and the temperature of the drying chamber is thirty degrees above zero.
The beneficial effects are as follows:
1. according to the sweet potato tip powder rich in amino acids and the preparation method thereof, the fresh sweet potato tip leaves are cleaned, so that soil, yellow leaves and rotten parts are not mixed in the process of preparing the sweet potato tip powder, and the taste and the quality of a final finished product are ensured to be good.
2. The amino acid-rich potato tip powder is prepared by mixing fresh potato tip leaves according to the weight ratio of 20: 1, the sweet potato tip powder rich in amino acids can keep the natural primary color of fresh leaves, the nutrient content can reach 96%, the sweet potato tip powder can be fully and directly absorbed by intestinal tracts of human bodies, and the essence of the sweet potato tips is prevented from being wasted.
