The invention belongs to the technical field of drying oligofructose powder, and specifically is a drying process for oligofructose powder with low water activity. A difference value CYZ is obtained by combining temperature, wind speed and power consumption, and a control value TKZ is evaluated according to the time variation trend of the difference value CYZ, so that the operation state of a drying tower can be judged more accurately, and an alarm is given in time to avoid more energy waste. When an abnormality has occurred in the drying tower and an alarm signal appears, an evolution module is established through non-standard working data of the drying tower in historical data, and data with the smallest power consumption value is selected from the evolution model as input data to obtain drying temperature data and wind speed data of the drying tower in an evaluation result. The actual drying temperature data and wind speed data of the drying tower are made consistent with those in the evaluation result through control, so as to reduce energy waste to the greatest extent.

The invention relates to the technical field of dairy product processing, and discloses low-sensitivity infant formula milk powder easy to digest and absorb, which is prepared from organic A2 raw milk, food-grade potassium citrate, galactooligosaccharide syrup, fructo-oligosaccharide powder, magnesium chloride, calcium chloride, organic demineralized whey powder, mixed vegetable oil and 1, 3-dioleic acid-2-palmitic acid triglyceride. The raw materials are added in sequence, micellar calcium is replaced with potassium citrate to loosen the structure, galactooligosaccharide syrup and fructo-oligosaccharide powder are embedded into micelles to construct steric hindrance, and magnesium and calcium ions are competitively combined to realize structural locking, so that the low-sensitivity infant formula milk powder easy to digest and absorb forms loose flocculent precipitate, and the low-sensitivity infant formula milk powder is easy to digest and absorb. The lipid component is utilized to physically shield the whey protein epitope in the homogenizing process, so that the sensitization is reduced, the lysine activity is retained, and the problems of dyspepsia and allergy are solved.
